Abstract

To help students develop successful strategies for learning how to learn and communicate complex information in cell biology, we developed a quarter-long cell biology class based on team projects. Each team researches a particular human disease and presents information about the cellular structure or process affected by the disease, the cellular and molecular biology of the disease, and recent research focused on understanding the cellular mechanisms of the disease process. To support effective teamwork and to help students develop collaboration skills useful for their future careers, we provide training in working in small groups. A final poster presentation, held in a public forum, summarizes what students have learned throughout the quarter. Although student satisfaction with the course is similar to that of standard lecture-based classes, a project-based class offers unique benefits to both the student and the instructor.

INTRODUCTION

A major challenge in teaching and learning cell biology is the enormous and continually expanding information base in our discipline. In just the year 2001, the National Libraries of Medicine PubMed database listed 136,775 articles with the word cell in their title or abstract. Nearly 6,300 articles published in 2001 contain the phrase "cell biology" or "cellular biology." This increasing wealth of information makes designing a series of courses that "covers" all aspects of cell biology virtually impossible during the 4-5 yr that an undergraduate student spends at the university. The challenge is even more acute for universities such as the University of Washington, where most students take a single 10-week class in cell biology without any required laboratory section.

Students at the University of Washington can obtain Bachelor of Science degrees in cellular and molecular biology, ecology, evolution, and conservation biology, botany, zoology, neurobiology, microbiology, or biochemistry. Several cell biology courses are offered, including an introductory class (Introduction to Molecular Cell Biology, Biology 355) and two upper-division courses (Cell Biology, Biology 401; Molecular and Cellular Biology of Plants, Botany 428). None of these classes is required for completion of any of the biological sciences majors, but the 400-level cell biology courses are electives for all the degree programs. In addition, many cellular and molecular biology majors choose to take Biology 401 and a two-quarter biochemistry series in lieu of three quarters of biochemistry. (A significant overlap exists between the content of Biology 401 and the third quarter of a year-long biochemistry series, Biochemistry 442.) About 75% of the molecular and cellular biology majors take Biology 401 during their undergraduate education at the University of Washington. Students entering Biology 401 have taken 1 yr of general biology, which includes approximately 15 weeks of instruction in cell biology, genetics, and physiology. Students also must have completed at least two quarters of organic chemistry and either introductory cell biology or an upper-division class in genetics, physiology, or biochemistry. Thus, students enter Biology 401 with considerable experience in traditional, content-driven courses that cover material relevant to cell biology.

Biology 401 is a 5-credit course, representing approximately one-third of an average student's 15-credit-hour-per-quarter course load. The traditional, lecture-based course meets four times each week in three 50-min lectures and one 2-h, teaching assistant (TA)-led discussion section during which students analyze portions of research papers (see http://www.washington.edu/students/icd/S/biology/401mbhille.html). Assessment of student performance is based on writing assignments, exams, and discussion-section participation. This traditional course design emphasizes learning key areas of cell biology content, as well as experimental methodology and analysis. Student evaluations at the end of the class indicate that they are well satisfied with the course (see http://www.google.com/u/washington?q=biol+401&hq=inurl%3Awww.washington.edu%2Fcec).

After several years of teaching a traditional version of the upper-division cell biology course, I became concerned that students were not learning how to learn cell biology. My emphasis on content encouraged them to learn a lot of facts and figures but did not foster a true mastery of the skills that would be important for life after college, much less for graduate school or for professional careers in teaching or biomedical fields. As a result, I designed a new course that replaced essentially all faculty-delivered lectures with student-led team projects on the cellular and molecular biology of specific human diseases. This course redesign has proven to be successful in helping students learn how to navigate the complexity and volume of knowledge in cell biology, as well as to gain insight and appreciation for cell biology research. In addition, because I have much more substantive interactions with my students, the course has renewed my own delight in and commitment to teaching.

LOGISTICS OF THE PROJECT-BASED CELL BIOLOGY COURSE

General Course Format

As shown in the syllabus (see Appendix A), the revised class meets three times per week for 2 h. The 2-h class period is important for providing a sufficiently large block of time for students to make progress on their projects and helps in scheduling team presentations. After experimenting with other daily schedules, I determined that holding class meetings on three consecutive days (e.g., Tuesdays, Wednesdays, and Thursdays) is ideal. This schedule usually eliminates missed class periods because of holidays, and the clustering helps students schedule their work hours and other commitments. This schedule also provides research-active instructors with larger blocks of time to focus on their own research.

The class period is used for occasional lectures, classwide discussions, team meetings, team project presentations, and evaluation reviews. The occasional lectures are given as the need arises to share information with the entire class. For example, I usually give a 20-min sample talk on a novel disease to serve as an example for the second presentation. In addition, I often give an informal lecture on broadly relevant research methods such as immunoblotting and cloning techniques. We also discuss effective writing strategies, slide design, and ways to make an effective poster, using examples from my lab and from previous classes. However, on most days no formal presentation is scheduled. Instead, students are allowed to leave the classroom as necessary to work on computers or in the library. The instructor and a graduate TA are available in the classroom to discuss any issue related to content, experiments, presentation skills, or writing. The instructor and the TA also frequently go to the nearby computer facility to discuss the project as students work. Project presentations occur during the 2nd, 5th, 9th, and 10th weeks of class.

Students are required to purchase an appropriate cell biology textbook, such as Molecular Biology of the Cell ( Alberts et al., 2002 ). The class is also given a list of the key cell biology research and review journals that are likely to be most useful in this class. Each team, in consultation with the instructor, identifies and assigns to the rest of the class appropriate textbook readings concerning their topic. For the second and third presentations, students are given instructor-chosen review articles and primary research articles as foundations on which to base their research and presentations. Students obtain from the library and the Internet additional information that is necessary to complete their projects. In early classes, a course web site was maintained that featured instructor-chosen information resources. However, this practice was discontinued because most of our current students are extremely skillful in doing Internet searches and did not find the class web site particularly useful. In addition, this resource did not promote the student's responsibility for and skill in obtaining and evaluating resources. Thus, instead of providing our own lists of relevant resources, we devote considerable class time to discussion of information literacy issues, including how to evaluate a potential source's reliability, and students are expected to find additional information on their own.

Projects

Four to five students work together as a team to research, prepare, and present both oral and written reports concerning the cell biology of a particular human disease. Depending on student input, the teams either focus on the same disease throughout the quarter or switch midway through the quarter. Student preferences are usually about equal on the matter of maintaining versus switching topics, and they realize the breadth versus depth trade-offs inherent in this decision.

The overall course is divided into four segments. The first three are punctuated with a paper and an oral presentation: the first segment focuses on the organelle or cellular process affected by the disease; the second segment deals with the cellular and molecular biology of the disease; the third segment focuses on recent research, with topics ranging from disease pathology to development of therapies to use of model organisms. The final segment is a poster presentation that allows students to bring all the information together into a coherent whole and serves as an impressively visible metric of how far they have come in their understanding and mastery of complicated information. The logic of this progression from simple to complex mirrors how most researchers, as experienced learners, approach new material. When confronted with a need to learn something completely new, we often begin with textbooks, move into review articles, and finally dig into the primary research.

Team Evaluation

At the beginning of each project segment, students receive an evaluation checklist that also serves as the grading standard for that project (see Appendixes B- D and Table ). Separate grades are given for the oral presentation and the paper. Evaluation of the work is explained in detail in a conference with the team, during which the focus is on what needs to be done to improve the quality of the presentation and paper. During this conference, we also ask questions about how the team is functioning and make suggestions for solving perceived problems with the process. After receiving this feedback (see Appendix A, Section IX, for an example) and that of the rest of the class, teams are usually allowed to rewrite their paper for a new grade.

Individual Evaluation

Full credit is earned by all team members who adequately contribute to the team project. The paper contains information about each student's individual contributions, including which student was the primary author of each section. In addition, the team maintains a project log that details each team meeting, who was in attendance, and what was accomplished (Table ). Finally, each team member completes a confidential evaluation of the contributions of all other team members (Table ). This information is typed up by the instructor to provide individual feedback (see Appendix A, Section X, for examples). By examining individual evaluations, the project log, the paper, and the individual portion of the presentation, the instructor can accurately evaluate whether each team member deserves full participation credit.

Initially, I was concerned about achieving fairness and accuracy in assigning appropriate grades to individuals that reflected both the quality of the group's work and an individual's contribution to that work. However, this system of checks and balances, together with the detailed conference with the team after each class segment, enables a substantive evaluation of student performance that is of potentially higher quality than that possible with traditional written exams. For example, the written documentation about the team process (log, individual evaluations, etc.) flags problems with equality of effort. These problems are discussed in the team conference, and members who did not contribute equally are given a decreased portion of the points earned. For instance, during the conference I may suggest that a particular individual appears to have contributed only 80% as much effort as that of the other team members. Often, the individual and his or her teammates admit the accuracy of the evaluation, and I assign the individual 80% of the total points earned by the team. Alternatively, the team members may explain the individual's contributions more accurately and that person earns full credit. Thus far, none of the end-of-quarter evaluations have revealed a concern by students that someone received a grade that he or she did not earn, which affirms that my assessment of an individual's grade is perceived to be fair and accurate.

Feedback

In the week following a presentation, the instructor meets with each team to review the grading, highlight the positive aspects of the presentation and paper, and point out areas for improvement. Each student receives a written synopsis of this critique, together with a typewritten summary of colleagues' evaluations of their contributions (see Appendix A).

Broadening of Learning and Individual Accountability

The philosophy of this class emphasizes group responsibility in contrast to that of the individual. Because the nature of modern biology also emphasizes group responsibility, as evidenced by the primacy of multiauthored papers, this emphasis is a valid representation of the current status of the cell biology discipline. However, as a way to encourage and evaluate each student's individual mastery of his or her topic as well as the topics of the other teams, one or two take-home exams or individual projects are assigned during the quarter. These exams or projects provide opportunities to promote greater breadth of learning and emphasize the importance of learning from one another. A sample assignment is to prepare a paper that compares and contrasts the molecular mechanisms of each disease presented in class.

Class Size

The size of the class is limited by the number of student presentations that can be effectively given within two class periods. The second and third presentations (cellular and molecular biology of the disease and recent research) require 30-min time slots: 20 min for the talk, 5-8 min for questions, and a few minutes to change to the next team. Consequently, a single class section that meets in 2-h blocks can include as many as 40 students (eight teams of 5 students). A class with more than 40 students would need to be broken into multiple sections, each with 40 or fewer students. The major factor determining the smallest class size for a team-based approach is the need to have a sufficient number of projects so that students are exposed to a breadth and variety of cell biological information. I estimate that a minimum of six projects is required to meet this breadth goal. Thus, the smallest class size that would function well in this team-based framework would be 18 (six teams of 3 students). In my experience, smaller groups do not function as effectively in building teamwork skills. However, if the teamwork aspect of the course is not a priority, the class could contain as few as 6 students, each working independently.

SELECTION OF DISEASES FOR THE PROJECT-BASED CELL BIOLOGY COURSE

Two major criteria drive the choice of a particular disease for inclusion as a topic for learning cell biology. First, a recent research paper concerning a cell biologically relevant aspect of the disease must be available. Consequently, selection of the specific diseases to use in a particular quarter begins with searches for one to three recent research papers that use a variety of experimental approaches relevant to cell biology. The second criterion for choosing a particular disease is to provide a balance of topics so that the class will be introduced to a broad spectrum of cell biological subjects. For example, I typically try to select a spectrum of diseases that, when considered together, represent most major organelles within eukaryotic cells.

Although partial understanding of the underlying pathology of most of the selected diseases is not essential, it is helpful. A balance of "we don't yet know" opportunities along with diseases whose molecular bases have been well deciphered seems to work best for the class as a whole. Appendix E lists the diseases that were chosen during the past 2 yr, along with references to assigned review and research papers.

PROMOTION OF EFFECTIVE TEAMWORK

The Challenge of Change

Probably the most frightening aspect of switching from lecture-based teaching to a project-based class is the challenge of making sure that teams work together effectively. Devoting most class periods to teamwork helps, because scheduling a time at which all team members can meet outside scheduled class periods is frequently impossible. However, simply having time to work together does not ensure that individuals within a team can actually work together effectively. To this end, the initial organizing of teams on the first day of class represents a critical nexus on which the success of the entire class rests. We devote most of the first 2-h class period to dividing students into teams and discussing how to work well in groups. Use of a "guild system," as developed by Dr. James Boggs, has proven extremely effective for promoting effective teamwork and setting the stage for students to learn how to interact cooperatively. Additional suggestions for effective team building in undergraduate biology classes are given by Allen and Duch (1998) .

The Guild Concept

Before establishing teams, we divide the class into groups, or "guilds," on the basis of each student's perception of his or her individual strengths. Four guilds seem to work well in building teams: 1) an administrator guild that organizes team efforts, 2) an artist guild that helps the team think creatively, 3) a communicator guild that facilitates interpersonal interactions among team members, and 4) an expeditor guild that steps in and performs functions as needed. After guilds are established, project teams are formed with individuals who represent each guild. Typically, each team includes only one individual from the administrative guild, but it can have multiple representatives from any of the other guilds.

The First Day of Class

After reviewing the syllabus, grading criteria, adds and drops, and other straightforward logistical issues related to the class, we begin by having each person tell us a positive adjective that describes one of his or her major strengths or "gifts." One way to help students think about this adjective is to ask them to tell us how their friends would describe them. After a few minutes, the instructor asks each student to share this adjective or phrase with the rest of the class.

One by one, each student gives a descriptive adjective, which the instructor writes on the board without comment so that the adjectives are grouped into appropriate sets. For example, "organized" would be written on an unlabeled section of the board reserved for people who will become members of the administrator guild. "Creative" would be written on the area of the board reserved for the artist guild. "Flexible" would be written on an area of the board reserved for the expeditor guild. "Friendly" would be written on an area of the board reserved for the communicator guild. Characteristics appropriate for each guild are listed in Table . The instructor keeps tabs on only the administrator guild types and works to ensure that the number of administrators equals the eventual number of teams. If enough administrators have been found, the instructor asks the student to provide a second adjective and writes that word instead of the one that was first offered. Because everyone has multiple strengths, this shuffling of individuals into other groups is not viewed negatively, especially because the purpose of the grouping has not yet been revealed to the students.

The students move so that they are sitting in groups as listed on the board and work together to select a guild name and motto. The students then discuss the positive contributions that their strengths bring to effective teamwork. Then, so that each individual can recognize the ways in which his or her strengths, if taken too far or used inappropriately, can cause problems for teams, the groups are asked to discuss the negative aspects of the guild. For instance, if someone in the administrator guild is "determined," he or she may drive the others too hard and cause discord in the group.

After the guilds explore their strengths and weaknesses, the whole class reconvenes to discuss the positive and negative contributions of their guild members to effective teamwork. The class examines each guild's perspectives of its roles in team efforts and spends some time talking about the advantages and challenges of working together. Finally, teams are formed with one individual from the administrator guild and the remaining members from each of the other guilds. On the basis of experimenting for 4 yr with larger and smaller team sizes, I settled on having teams with four or five members as being ideal for spreading the work out equally and for buffering personality conflicts.

After introducing themselves to one another and spending time obtaining contact information, the teams are immediately set to work. They select a number from a hat and receive a corresponding folder that contains a story about an individual with the disease that they will be researching for the quarter. References to the identity of the disease have been removed from the story, but students are told that the disease is caused by a single genetic defect. They are asked to work together to devise a hypothesis to explain what cellular structure or process is altered as a result of the mutation.

The Structuring of Team Efforts

The initial three to four class periods are structured so that the teams must work together to complete specific tasks, such as learning how to do BLAST (Basic Local Alignment Search Tool) searches to identify their gene of interest. As the quarter progresses, direction from the instructor is gradually reduced to the point that the team does all planning for upcoming events. Appendix F provides an example of a structured activity that helps the teams learn how to plan and organize their projects.

Guild Meetings

Teams work together for several class periods, then a short guild meeting is called in which guild members can discuss what is working well in their groups, what problems are arising, and which ways they can effect positive change in their team. Such meetings are more important in the early weeks of the class (i.e., just before and after the first presentation) than later in the class. Teams seem to rapidly settle into a clear understanding and appreciation of each person's role and move forward with the tasks at hand. In addition, students learn to take on multiple roles as their talents and interests allow. Thus, the most important gains provided by the guild exercise may be in forming more "balanced" teams and in helping students realize, appreciate, and respect their teammates' abilities and contributions.

VALUE OF THE PROJECT-BASED CELL BIOLOGY CLASS

More than 60% of all students who enter the University of Washington think that what they will learn in their major will be "extremely important" for their success after leaving college. 1 However, when our students are surveyed 5-10 yr after graduation, only slightly more than 25% of the students find that what they learned in their major is "essential" for their current primary activity. 2 In contrast, the perceived importance of skills such as communication, problem solving, leadership, and working together effectively increases. Not surprisingly, students believe that their university training does a good job "teaching them their major" but not as well in helping them gain the skills that they tell us are important for success after college. The unfortunate conclusion is that we are doing a good job teaching our students things that may not matter much in the long run. The desire to make a long-term difference in students' lives and careers was one factor that motivated our developing a project-based cell biology class.

Project-based cell biology moves the students away from a focus on content to a clearly defined focus on communication, leadership, teamwork, and other skills needed for lifelong success, while modeling how scientists in general, and cell biologists in particular, learn new material. Although many students act as if they have been waiting all their lives to be allowed to tackle a problem creatively, others students are less comfortable with such open-ended activities ( Hansen and Stephens, 2000 ). As a consequence, my course evaluation scores remain essentially the same whether I teach a traditional lecture-based cell biology course or a completely project-based course. The student-perceived "effectiveness of the instructor" is usually decreased for the project-based course, probably because I am facilitating their independent learning rather than lecturing.

The most common criticism from students in the project-based course is that they think they did not learn as much as they would have in a lecture-based class. I believe that part of this dissatisfaction is an illusion; students appear to base their perception of the amount that they learned on the number of pages of lecture notes that they accumulate or the number of chapters that they were assigned to read. Student satisfaction with problem-based cell biology increased when I began handing out all the team articles and project papers and asking students to search for connections between their disease, organelle, process, and so forth, and those presented by the other teams ( Appendix G). The amount of information we were "covering" became obvious as their notebooks filled with the presentation notes and papers from each team, as well as the entire complement of review and research articles for all the class projects.

An initial concern of many students confronting a project-based course for the first time stems from the requirement that they work in groups. Some students worry that their grades will suffer or that other team members will not work as hard and they will consequently receive a grade that they do not deserve. The underlying concern appears to be one of fairness. The integrated system of checks and balances (project logs, confidential team member evaluation, etc.) helps assure students that grading will be fair and take into account individual contributions. End-of-quarter evaluations confirm that the students perceive the grading to be fair, which indicates that these initial fears were unfounded. To deal with perceptions that an individual effort would be of higher quality than a group effort, I occasionally allow an individual to turn in a paper that represents his or her exclusive effort. With only one exception thus far, individual efforts are of poorer quality and receive lower grades than those of the corresponding team efforts. Once students see this result, they quickly become converts to the team approach.

In assessing course effectiveness, an initial issue is the student composition in the traditional classes versus that in the project-based class. Because the traditional classes are offered during the academic year and the project-based class is offered in the summer, the two types of classes may serve different populations of students. Comparisons of the summer 2000 class (project based) and the autumn 2000 class (traditional) uncovered two interesting differences: on average, students taking the project-based class had less than half as many transfer credits as those taking the traditional class, and the summer class contained four nonmatriculated students. Nonmatriculated students are rarely included in the academic-year Biology 401 classes because of high demand for the class by matriculated students. Despite these differences, both classes appear to include students with similar academic potential. For example, both classes have similar overall grade point averages (3.1 for the summer 2000 class [project based] and 3.2 for the autumn 2000 class). In addition, both classes have similar graduation rates: 83% of the summer 2000 class (project based) and 85% of the autumn 2000 class had obtained a biology degree by spring 2002. Most students in both classes are molecular and cellular biology majors.

Direct comparisons of student performance following lecture-based versus project-based courses are difficult or impossible because the two courses have different learning objectives and outcomes. However, one measurement of the effectiveness of project-based learning is evaluation of student performance at the beginning and at the end of the quarter. In the summer 2001 class, the average grade for the first project presentation was a "B" and the average paper grade was a "D." By the second project, the average presentation grade improved to a solid and impressive "A," a gain that was maintained in the final presentation, which also was "A"-quality work. The average paper grade on the second project improved to a "B+" and was an "A" for the third project. The rapidly improving and generally high grades in the project-based class demonstrate the ability of students working in teams to meet and often exceed even very high expectations.

Because of the nontraditional focus and format of the project-based cell biology class, one concern is that it may not prepare a student for subsequent traditional biology classes as well as a lecture-based cell biology class does. We do not have access to students' graduate record examinations (GRE) or Medical College Admission Test (MCAT) scores. Consequently, to assess this possibility, we compared the grades of the students taking Biology 401 in summer 2000 (project-based class) with those of the students taking Biology 401 in autumn 2000 (traditional class). The comparison, shown in Table , indicates that students taking the project-based class and those taking the traditional class had similar grades in subsequent biology classes. Thus, taking the project-based class did not adversely affect student performance in subsequent classes.

Table 5

Perhaps as important as the students' improved performance during the quarter and their overall satisfaction with the course (see Appendix H) is that teaching a project-based class energizes me as a teacher and as an individual. I have learned new skills and approaches by watching how my students interact with one another. For example, one team struggled with an unusual team member, to the point that I offered them the option of essentially "voting the person off the island." The team refused and, through their gentle but persistent efforts, was able to develop strategies for interacting with the recalcitrant individual, which enabled this person to contribute in substantial and novel ways to the team's efforts. Seeing such dedication in my students inspires me to greater efforts to teach all my classes in a way that is inclusive and more understanding of different learning styles, personalities, perspectives, strengths, and weaknesses.

Some of my students have been incredibly creative in ways that I would never have had the opportunity to see if I had not relinquished "control" of the class. For example, one team got in touch with a local epidermolysis bullosa (EB) support group and became acquainted with a young man who had this disease. They invited this young man to talk to the class about what it was like to live with EB. I have rarely seen a class as engaged, actually riveted, as when this young man talked about the traumas of being ridiculed when he was in elementary and high school for having to sit out of physical education classes or wear shoes several sizes too large. This engagement translates itself into a wonderful and welcome benefit: I have never heard a single student in my class ask, "Do I need to know this?" or "Is this going to be on the exam?" Life is the exam, and my students tell me that their experiences in our project-based class help prepare them for future academic and personal challenges.

Assessment

Data are taken from anonymous course evaluation forms completed at the end of the summer 2001 quarter. Thirty students responded, but not all questions were answered by all students. For some questions, an individual may have reported more than one answer. In these cases, all of the answers were used. Examples of statements were randomly chosen from answers that contained complete thoughts rather just a "yes" or "no" answer.

I was initially excited at first with the idea of working in a team because I like working with a small group and thought that this would lighten the course work per person.

I did not like the format because I don't like depending on other people's performance for my own grade.

I didn't think it was as valuable as I do now. It concerned me a little about group work time that would be required-how that might work.

Liked it a lot; I enjoy teamwork to combine my ideas.

Initially I was a little worried since sometimes groups can be challenging and frustrating!

Part of me was stoked because there weren't any big tests, but another part of me was pissed because attendance affected my grade.

I liked it and I didn't like it. I liked it because I thought the class would be more interactive & I would learn more; I didn't like it because I didn't want my grade to depend on others' work.

I thought it was a relief!

I thought it would be interesting, but I was a little wary of working in groups because they can be hard to work with.

I liked the concept initially. It sounded great because it was unlike any other class I had taken here.

I was looking forward to it until we got our first presentation grade. At that moment, I wished we didn't work in group.
Now that the class is over, what do you think are advantages and disadvantages of learning and doing projects in teams?
The advantages are that people can compensate and cover for fellow teammates. Also, teams can brainstorm for really creative ideas and sometimes a person can research part of the project that interests him/her the most. The disadvantages are that there might be conflicting working styles and personalities. Furthermore, one would have to be willing to compromise on ideas regarding papers, presentations, etc.

Teamwork forces people to work a little harder so you don't let your team members down. The disadvantage would be, some members may skate by on the work of the more motivated members.

Advantages-you learn more, cover more ground than you could by yourself; something may be uninteresting to one but interesting to another in your team.

Presentation & how to write scientific paper was greate [sic] opportunity. Even the [sic] only one member of the group doesn't work seriously, all group member [sic] get worse.

Advantage: more people = more ideas and more knowledge; Disadvantage: hard to coordinate our schedules for meeting times.

It was a big weight off, since I wasn't responsible for everything. Also, I think the final outcomes were much more creative than I could have done myself.

I'm more apt to ask for and receive criticism of my own work in the context of a team. However, all projects take several times longer to complete. The projects, of course, are usually of better quality.

Advantages: Get more info & do projects faster and better; Disadvantages: some people care more & do a little more work & the teacher can't see that.

Cooperative Learning in Biology WHY Cooperative Learning? Collaborative Groupings "It is the long history of humankind (and animal kind, too), those who learned to collaborate and improvise most effectively have prevailed" Community is a Must! Collaboration is not possible without a community Community fosters a feeling of belonging, trust, and confidence Positive Learning Environments must be developed and maintained to allow cooperative learning.
