Co-Teaching Benefits, Beliefs, and Basics

# data[].attributes.body
Although co-teaching has many benefits, it is hard to accomplish and accomplish well. It will take time and effort to find the right balance between two teachers in one space. There must be mutual respect and understanding before co-teaching can flourish. Once it does, it is great for all involved!

# data[].attributes.attachment_link.readable_text
As more schools move toward inclusion, integrated co-teaching (also known as collaborative team teaching) is becoming more common. However, not all teachers are familiar with co-teaching models, the planning and collaboration it takes, or the different ways it can look in a classroom.

Co-teachers are often general education teachers and special education teachers working together in the general education classroom. You plan lessons together and teach together to support the diverse academic and social-emotional needs of all students - those who have been identified as having a disability and those who haven't.

Studies show that this co-teaching can successfully meet the needs of all learners when the co-teachers:

Have ample time to build a trusting relationship with one another

Have shared planning time

Each have the chance to use their expertise in the classroom

There are six basic models of co-teaching. Read on to learn how each model works, what it looks like in the classroom, and when to use it. You'll also learn about the benefits and challenges of each co-teaching model.

1. Team teaching

In team teaching, both teachers are in the room at the same time but take turns teaching the whole class. Team teaching is sometimes called "tag team teaching." You and your co-teacher are a bit like co-presenters at a conference or the Oscars. You don't necessarily plan who takes which part of the lesson, and when one of you makes a point, the other can jump in and elaborate if needed.

Team teaching can make you feel vulnerable. It asks you to step outside of your comfort zone and allow another teacher to see how you approach a classroom full of students. However, it also gives you the opportunity to learn about and improve your teaching skills by having a partner who can provide feedback and - in some cases - mentorship.

In team teaching, as well as the five other co-teaching models below, a teacher team may be made up of two general education teachers, two special education teachers, or one of each. Or in some cases, it may be a teacher and a paraprofessional working together. Some IEPs specify that a student's teaching team needs to include a general education teacher and a special education teacher.

Here's what you need to know about the team teaching method:

2. Parallel teaching

In parallel teaching, the team splits the class into two groups and each teacher teaches the same information at the same time. Parallel teaching works well to differentiate instruction when the content being taught is particularly challenging. Students can benefit from learning difficult material in a smaller group.

Parallel teaching can be a comfortable way to start co-teaching. You and your co-teacher plan together to make sure you're covering the same material. And since you're teaching your half of the class, you're less likely to feel closely observed by your colleague. Here's a closer look at parallel teaching:

What it looks like in the classroom
The class is divided into two groups, and both teachers teach the same information simultaneously in different sections of the room.

Benefits

Provides both teachers with an active instructional role

Lowers the student-teacher ratio and reduces the load of teaching a large class

Allows for small group instruction, which can be especially helpful for students who learn and think differently

Gives students the chance to ask more questions during lesson time

Provides a chance for students to work in heterogeneous groups (made up of varying abilities instead of groups of students with similar strengths and challenges)

Keeps the academic rigor of a demanding lesson, but splits the responsibility between both teachers

Challenges

Requires both teachers to have strong knowledge of the content so students will learn the same thing

Can be challenging to control for noise, distraction, and space when working in the same classroom

Requires careful timing to make sure both teachers end the lesson at the same time

3. Station teaching

In station teaching, the class is divided into three or more groups and the classroom has multiple learning centers. As the students rotate through the stations, the teachers teach the same material in different ways to each group. For example, fractions may be taught with a fraction line at one and with cubes at another. If there are more stations than teachers, some stations may be student-led and at least one will focus on independent work or practice opportunities.

Both you and your co-teacher are responsible for planning and teaching an in-depth concept that helps meet the overall lesson goal. Learn more about station teaching:

What it looks like in the classroom
Different learning stations are set up in various areas of the classroom, one for each teacher and at least one for independent student work.

Benefits

Provides both teachers with an active instructional role

Allows teachers to use flexible grouping to tailor teaching to each group's needs

Lowers the student-teacher ratio

Resets student focus with each station rotation, increasing engagement

Provides time for students to engage with the content on their own as well as with teachers

Supports a UDL approach to teaching

Allows for more material to be covered in a shorter time frame

Provides a clear teaching responsibility for each adult in the room

Challenges

Requires significant planning for teaching and material preparation

Students may not get to all of the stations if they're not moving at the same pace

May be noisy and distracting for some students

Requires pre-teaching around expectations for independent work time

4. Alternative teaching

In alternative teaching, one teacher instructs most of the class and the other teacher teaches an alternate or modified version of the lesson to a smaller group of students. Alternative teaching is also sometimes described as "big group/small group" teaching.

Small groups are often put together based on students' learning needs. You and your co-teacher will need to find time to look over student data. This will help you figure out which students need support filling in gaps in background knowledge, which students need remediation, or which students could benefit from accelerated learning because they already know the content or have mastered the skills of the large group lesson. Here's more of what you need to know about alternative teaching:

5. One teach, one assist

In the "one teach, one assist" model of co-teaching, one teacher teaches a full group lesson, while the other teacher roams and helps individual students. This is sometimes called "one teach, one support," because the second teacher often provides additional support for learning or behavior management.

This model of co-teaching can be difficult to negotiate because it may leave one teacher feeling more like an assistant. Building a strong relationship with your co-teacher and talking through when it makes sense to swap roles can make it easier. That's key to making sure that both of you have a chance to teach content and to provide support to students one-on-one.

Debriefing after a lesson is also key. Both of you need to know which students needed extra support during the lesson, what that support looked like, and what each student was struggling with. Here's what you need to know about this co-teaching method:

6. One teach, one observe

In a "one teach, one observe" setting, one teacher serves as the primary instructor, while the other is simply observing students' learning and collecting data, which can be useful in:

Determining what instruction takes place next

Seeing which students need additional help

Deciding what co-teaching model may be used next to address any identified needs

Identifying and tracking helpful school services, such as IEP, 504 plan, functional behavioral assessment (FBA), behavior intervention plan (BIP), or response to intervention (RTI)

Making co-teaching work

Co-teaching definitely has benefits, but it can also be challenging to implement. It can be especially hard for new teachers who are paired up with teachers who have more experience, or for co-teachers whose teaching philosophies differ from each other. But there are several steps you can take to help make co-teaching work:

1. Plan who's doing what. No matter which co-teaching model you use, you and your co-teacher need to thoughtfully plan out which responsibilities each of you will have. Planning is vital to your success as a co-teaching team.

2. Agree on expectations. Having a conversation before the year begins about your expectations for students, behavior, homework, bathroom use, etc., can help you work out any differences you may have and come to a consensus for how your shared class will run.It's also essential that both teachers share behavior management equally. Avoiding a "good cop/bad cop" situation can make it easier to maintain a positive classroom culture.

3. Understand the needs of all of your students. It's critical that both you and your co-teacher understand the needs of all of your students, including those who learn and think differently. Knowing how to read an IEP or 504 plan, implement accommodations, and participate in IEP meetings is a shared responsibility.

4. Use signposting. Making sure both of your names appear on the door, on assignments, and in the classroom can also help your students see you as the team you are.

5. Keep setting aside time to collaborate. Planning and reflecting on the lessons you teach together is especially important. Keeping lines of communication open, raising concerns respectfully, and having a supportive and involved administrator can help bridge any gaps.

One of the biggest things when thinking about making co-teaching work is to have clearly define roles and responsibilities in the classroom. When co-teachers are not on the same page, things will go overlooked because one teacher may assume the other teacher is handling it.

Impossible. That was my first thought when I saw the class roster. In one of my ninth grade English classes, 13 of my 27 students had IEPs. Additionally, about one-third of the students had failed the class the previous year. I dreaded the first day of school. But then something wonderful happened: The principal assigned me a co-teacher, a special education expert to serve as another set of hands (and eyes and ears!) during this class every day. I was thrilled.

My co-teacher Sandie was a joy to collaborate with, but our relationship was by no means perfect, especially at the beginning. We often struggled to find planning time. Sometimes we disagreed about how to best help a particular student. However, we nurtured the co-teaching relationship and, in time, found a rhythm that worked for us-and for the students we served.

In the years since I co-taught with Sandie and other teachers, I've coached and consulted with dozens of successful and not-so-successful teams. Co-teaching, when done well, offers benefits for both students and teachers. When not done well, it can be confusing or downright frustrating for all involved. If you are or will be part of a co-teaching partnership, this post will show you some ways to make your partnership work beautifully.

What is Co-Teaching?

In a co-teaching relationship, also known as a "push-in" arrangement, a general education teacher partners with a specialist who may be certified in teaching English Language Learners (ELLs), students with learning disabilities, or some other special population. A co-teaching team works in the general ed classroom; for the majority of the time, students with special needs are not pulled out to receive services in another location.

For instance, a middle school social studies teacher may have an ELL teacher co-teaching with him during one class period because five students in that class are newcomers to the United States and speak only Arabic fluently. A high school teacher may have one or two sections of biology to which many students with IEPs for reading are channeled; a co-teacher who specializes in reading disabilities co-teaches in these classes. A 4th grade teacher may have two students with 504 plans and another three who have specific learning disabilities in her class; she works alongside a special education teacher daily during lessons in the four core academic subject areas.

Co-Teaching Structures

General education teachers working with specialists in a "push-in" model often work in one of the following structures described by Friend and Cook (1996):

One teach, one observe: One teacher delivers instruction while the other observes student learning. Usually the observer collects data on student understanding so that the co-teaching team can better plan future instruction. Sometimes, specific students are watched closely so that the teachers can determine new strategies to use with them.

One teach, one assist: One teacher takes the lead in providing instruction while the other moves around the classroom, assisting struggling students. This help is not limited to students with special needs; the assisting professional is there to serve whomever needs support.

Parallel teaching: The class is divided in two groups and the same material is presented simultaneously by both teachers. The teachers plan the two groups deliberately to maximize the success of all students; this is not simply a "pull-out" or intervention group sitting in the same room.

Station teaching: Both teachers are actively involved in instruction as students are divided into groups and rotate from one station to the next. There may be stations where students work independently or with a paraprofessional in addition to the two stations the co-teachers facilitate.

Alternative teaching: One teacher takes a small group of students and provides them more intensive or specialized instruction that is different than what the large group receives from the other teacher.

Team teaching: Both teachers teach the content at the same time in tandem or "tag team" fashion.

It is important to note that both teachers have equal status and equal responsibility in all six of these arrangements. In the co-teaching relationships that work best, at no time is one teacher seen as subordinate to the other. Both professionals are credentialed professionals, although each may have his or her specific areas of expertise.

How to Make the Most of a Co-Teaching Partnership

Researchers and practitioners have tons of advice about how to co-teach effectively, and as a person who has been "in the trenches" with several different co-teachers, so do I. The advice below sums up the most common recommendations.

1. Respect each other.

Not surprisingly, mutual respect is critical to the co-teaching relationship. You'll have to share ideas openly and do much of your work facing students together, so respecting each other is paramount. Sometimes you'll disagree, and that's to be expected. As co-teacher and ELL specialist Melissa Eddington says, it's fine to disagree with someone's ideas, but don't make the disagreement about the person.

Teachers in co-teaching situations that don't work well often report feeling disrespected. Amy* is an ELL specialist paired with a middle school social studies teacher. When they collaborate, Amy feels her suggestions for tweaking whole-class lessons are not taken seriously by her partner. "She respects me as a professional," Amy says of her co-teacher, "but I think because I'm not experienced in her content, she doesn't see my input as valuable."

Susan*, who is licensed in both secondary science and learning disabilities, works with two physical science teachers and one biology teacher. The physical science teachers welcome her ideas and eagerly adjust their lessons based on her suggestions. They are seeing a steady increase of students mastering the required standards in the classes Susan supports. The biology teacher, however, dismisses many of Susan's ideas and accuses her of "dumbing down" his content. Susan feels disrespected and finds it hard to even be in the room with the biology teacher because he constantly positions himself as "the expert" and places her in a subordinate role.

Words and gestures speak volumes. Take care to show respect for your partner in all you do.

2. Clearly define roles and responsibilities.

Co-teaching works better when the partners agree on who does what, when. Clearly defined roles and responsibilities prevent either partner from feeling the other has overstepped a boundary or shirked responsibilities.

Natalie Marston (2002-2015), an elementary special ed teacher, recommends co-teachers reach agreement on scheduling, classroom procedures and behaviors, classwork and homework policies, grading, and school/home communication together so they present a united front at all times.

Obviously this type of planning requires a great deal of time, ideally before school starts. If extended time is not available prior to the beginning of the school year, then the co-teaching team should expect to put in extra hours before and after school in the first few weeks so things get off to a good start.

My co-teacher Sandie and I did not have advance warning of our assignment. We found out about it on the first teacher workday, leaving us only a few days before the students arrived. For weeks, we both felt like we were playing "catch up and keep up," but found that having lunch together (and some happy hours together) helped us stay in sync.

3. Be flexible.

Innovation is difficult. That's why so many teachers find themselves falling back on comfortable (and even tired) activities and strategies. Co-teaching allows you to gain another person's perspective on how instruction might be improved, how students might be best assessed, what resources to use, and so much more. Sometimes this means one person has to put aside his or her favorite tried-and-true strategy and try something different.

When Susan suggested a tactile, quiz-like method for reviewing the periodic table to her physical science co-teaching partners, they were skeptical about the time and materials it might require. They initially felt it would be more efficient to simply give additional notes to their students and then pair students to quiz each other. However, they agreed to try the review Susan's way. The students loved the activity, and almost every student with special needs passed the chapter test two days later. All three teachers were thrilled and committed to using the activity in future years.

4. Plan together.

The co-teaching relationship brings together two people with wonderfully rich expertise and experiences. Special educators are typically skilled in individualizing curriculum and instruction based on children's needs (Dettmer et al., 2005; Volonino & Zigmond, 2007). General educators, on the other hand, tend to have broad knowledge of the curriculum, standards, and desired outcomes for the larger group. Therefore, when general educators plan lessons, they tend to aim for the masses (Dettmer et al., 2005). Both perspectives are important, and co-teaching teams need ample planning time to work through how to best utilize each one.

Lack of planning time can lead to territorialism. Without time to plan for a good balance of content and individualization, a general ed teacher may become protective of his subject matter, or a specialist may become protective of his students. Emma*, a high school special ed teacher partnered with two geometry teachers, has experienced this. One teacher often asks Emma to pull aside the five or six students with specific disabilities within his class and work only with them. He sometimes says to her, "You worry about your kids. I'll worry about geometry." The principal is now providing an additional hour of planning time for Emma and this teacher. An assistant principal who oversees the math department facilitates the meetings so Emma feels supported and the geometry teacher has another content-area expert to hash things out with.

Keep in mind that planning must include both instruction and assessment. Considering many students with special needs have legal accommodations for assessment (like being provided translation, extended time, or oral reading), it's best to include both partners fully in designing quizzes, tests, papers, and other high-stakes assessment tasks.

How much time is ideal? One study found that co-teachers desired, on average, 15 minutes to an hour each day for planning (Dieker & Murawski, 2003). This figure corresponds to what worked for my co-teacher and me, and it also confirms what I hear from many co-teachers in the field. Strive to find that time any way you can.

5. Don't take yourself too seriously.

Innovation requires failure. Many times, teachers feel they've failed somehow during instruction, and in reality, the students haven't even noticed. We are often our own worst critics. Revisiting or correcting something later in the day (or the next day) doesn't mean you failed earlier. It means you've learned something since. This is the kind of ongoing learning we want to model for our students.

And, as in most situations in life, a little bit of humor goes a long way. Laugh with your co-teacher. Allow students to see both of you laughing with each other and with them when something is surprising, silly, or just doesn't go the way you planned. In the words of Jennifer Wolf who co-teaches with Melissa Eddington, "Take the work seriously, but don't take yourself too seriously."

Eddington adds, "You gotta laugh at each other! Our job is hard, and if you're not laughing and making light of some things, then it's just not going to be a good place to be."

6. Communicate, communicate, communicate.

Planning time is one thing; constant communication is another. Not only should co-teachers frequently plan for what standards will be covered, how material will be taught, and how students will be assessed, they should also regularly communicate in less formal ways.

Co-teaching teams have different methods to create and sustain that communication:

Eddington and Wolf use the Voxer app throughout the school day and on their drives home to send messages back and forth. Voxer works like a walkie-talkie and allows back-and-forth conversation in real time when two people are not physically close to each other. Melissa says, "We're constantly communicating. We're talking about specific students. We're looking at assessments to see what areas are lacking...different things we want to bring to the classroom, things we don't want to do..."

Some other teams I've worked with use texting and emails throughout each day to share updates. Voxer, texts, and emails can all work well, especially if one teacher has urgent information or an urgent question about a particular student.

Teams can use Google Docs or other shared documents to keep track of lesson planning and to share feedback with each other on how lessons went. Collaborative documents can also be used to provide each other with information about targeted students.

In addition to ongoing communication, Ariel Sacks (2014) reminds us to periodically check in with our co-teacher about how we are doing in general. She recommends asking your partner the following:

Are there management items we should clarify, such as when are students allowed to go to the bathroom?

Are we sharing airtime well?

Are we dividing grading in an equitable way?

Would different teaching formats better utilize the two of us in the classroom?

Finally, co-teachers need to present a united front when dealing with parents. Some partners go as far as to create a shared email address from which all communication flows. This may or may not be practical in your situation. At the very least, important parent communication about a student's progress should be drafted by both parties.

For more in-depth information about communicating and collaborating with your co-teacher, see Communicating and Collaborating in Co-Taught Classrooms (Conderman et al., 2009).

7. Seek administrative support.

Sometimes, teachers have been scheduled to co-teach by administrators but didn't have much advance notice. This is what happened with Sandie and me. We were able to find snippets of time during the school day to use for planning and checking in with each other, but we had no common planning period. If you and your partner don't have a common planning time when you can frequently collaborate, ask for it. Go to your principal with a couple of proposals about how this can work without too much disruption to the rest of the schedule.

Sometimes co-teachers may not understand fully why they are being asked to team. If this is the case, ask for a meeting with the principal and any others responsible for the assignment. Ask them why they thought the two of you would be a good fit and what they hope you will accomplish with students.

If you're already in a co-teaching partnership that's not working well, and you've tried to address this with your partner, turn to a trusted administrator next for advice. If you and your co-teacher have not recently been observed, ask the administrator to come sit in on part of a lesson. Tell him or her what you'd like feedback on or what feels like it's not working well. Debrief with the administrator, ideally with your co-teaching partner. When an observer offers data and feedback to both of you, it may feel different for your partner than when you share things from your perspective. (This co-teaching observation form can help.)

It's important not to go to other teachers with your concerns. Respect the collegial relationship you have with your co-teacher and don't do anything that might undermine it. And it should go without saying that you don't want students to perceive any problems within the co-teaching relationship. Be cognizant of your demeanor, tone, and body language. Students are quite perceptive and can easily spot trouble. They are also experts at "good cop/bad cop." Don't let students play you and your partner against each other. If your colleagues or students give you any evidence that they know the co-teaching arrangement is ineffective, head straight for that trusted administrator to support you. ♦

Teachers must have mutual respect for their co-teachers to make it work in the classroom. It is very helpful when teachers are on the same page because it helps increase the success rates of students learning a content area. Special education teachers should be seen as a co-teacher in a classroom to really make the environment work for the students with learning disabilities.

# data[].attributes.attachment_link.readable_text
In Lauren Eisinger and Kara Houppert's co-taught 5th grade classroom, every instructional choice requires a lot of planning.

When Eisinger, a special education teacher at Naples Elementary School in upstate New York, and Houppert, a 5th grade teacher, wanted to start a class book club last year, they knew they would have to think creatively to accommodate reading levels spanning 2nd to 6th grades.

So they did a "book tasting," giving students a choice among several different, appropriately-leveled texts. Once they grouped students, teachers ran the activity like "more of a guided reading," said Houppert, with both of them reading aloud to different groups to support special education students who struggled with fluency and decoding.

"You need to be very flexible, and underneath everything, you need to trust each other," said Eisinger, who co-teaches 1st and 5th grade classes at Naples Elementary. "If you don't have that kind of mindset-that you're both there to do the best that you can for your kids-I think it would be really difficult."

Co-teaching, in which a special educator and a general educator share the responsibility of instructing and assessing students, has long been a standby in inclusion classrooms, which encompass both general education students and those with disabilities.

When done well, co-teaching should enable students with disabilities to receive the general education curriculum and special services that they need in the same setting, said Sara Cook, an assistant professor at the University of Hawaii at Manoa, who researches special education.

But for it to work, teachers need the time, training, and resources to effectively integrate their distinct instructional expertise, said Marilyn Friend, a co-teaching expert and professor emerita of education at the University of North Carolina at Greensboro.

"Co-teaching used to be called a professional marriage, and I'm kind of tired of that metaphor," she said. "It really needs to be more like a business partnership."

Research Is Mixed

Co-teachers should have parity in the classroom, Friend said. And in Eisinger and Houppert's 5th grade class, they co-sign all emails to parents; both of their names and pictures are displayed in the classroom.

But even though they're equals, co-teachers shouldn't perform the same roles, Friend said. While general educators are the experts in the curriculum and content, special educators devise and implement a plan for addressing students' individualized education programs.

It's difficult to determine how many students are in co-taught classrooms nationally or how popular co-teaching is in comparison with other inclusion models.

The federal government collects data on special education students' instructional environment: In 2015, a little more than 60 percent of students spent 80 percent or more of their day in a general education classroom. But there's no information included on how students are receiving services, Friend said.

Still, she said, there's evidence that co-teaching is becoming more popular. "A lot of states with high populations are really actively encouraging this as a service model," said Friend, citing Texas, which revised its co-teaching guidance this year, and California, which has scaled up its co-teaching efforts over the past several years.

Findings on co-teaching's effect on student outcomes are mixed, said the University of Hawaii's Cook. (The Center for Exceptional Children's 2018 practice recommendations for co-teaching, which Cook co-authored, suggests that educators proceed with caution.)

"It is hard to determine, from current research, what may make some co-taught classrooms more effective than others as co-teaching is not always clearly described in studies," Cook said. The strategies and interventions used aren't always explained, she said.

"Research should look at what's happening in the co-taught classroom," Cook said. "Are teachers using evidenced-based practices in the classroom to meet the individual needs of students?"

Time: The Key Component

The Naples school system, where Eisinger teaches, doesn't yet have comprehensive results regarding whether co-teaching has raised student achievement, said Katie Piedici, the director of pupil-personnel services in the nearly 700-student district. But the model has helped the district put more students in the least-restrictive environment, she said.

To meet student needs in their classes, Eisinger, Houppert, and 1st grade teacher Brittany Ritz use different strategies from day to day and lesson to lesson.

In the 1st grade classroom, for example, one teacher sometimes leads whole-group instruction while the other provides support, or students will break into teacher-led math and reading groups.

"I have some kids right now who struggle with just knowing that they have five fingers on each hand," said Ritz. Still, she's able to keep the pacing of the general curriculum consistent, she said, as Eisinger can work with students who need modifications to master foundational skills.

To do this kind of collaboration, all three teachers said, they need time-to plan together, to debrief lessons, to talk about how they want the classroom to run.

Eisinger shares one 40-minute planning period a week each with Houppert and Ritz, a scheduling triumph she attributes to her school leaders intentionally making time for co-teachers to work together.

The district has communicated the expectation to building leaders that co-teachers need this time, Piedici said. Pairs also have a half day they can take during the year to catch up on planning, and new co-teaching partners undergo summer professional development.

It's important that school systems have a plan for how to prepare, schedule, and set norms for co-teachers, said Friend. "It doesn't matter how good the teachers are: If there's not an administrator really actively supporting [co-teaching], it's really difficult to implement and sustain."

District-sponsored training was Ritz's main introduction to co-teaching-she doesn't remember her general education preservice program covering the model in any detail.

Some general education programs offer courses that address co-teaching, like Syracuse University, which requires all elementary teacher-candidates to get dual certification in special education. But many programs at the middle and high school levels don't cover the method, Friend said. "It varies wildly."

The Naples district sent Ritz and two other co-teachers to a conference, and she also attended workshops in the district. She learned how to use different co-teaching methods-parallel teaching, team teaching, small-group instruction. "Before then, I really had no idea what those even meant or would look like," said Ritz, who has taught for eight years at the school.

As the sole classroom teacher, "You don't really need to communicate to someone else what you're doing or how you're thinking," Ritz said. "You just do it." Looping in a co-teacher on all her plans was a hard adjustment to make at first, she said, and something she still struggles with occasionally.

During especially busy weeks, co-planning periods can get taken up by other tasks-like prepping for parent-teacher conferences, Houppert said. In those instances, she and Eisinger rely on the professional relationship that they've built. It's important, said Houppert, that she knows Eisinger will be able to jump right into a math lesson with just a two-minute briefing about what they're doing that day.

"It takes a lot of communication, and realistically, it does take a lot of trust in one another," Houppert said.

In Lauren Eisinger and Kara Houppert's co-taught 5th grade classroom, every instructional choice requires a lot of planning. When Eisinger, a special education teacher at Naples Elementary School in upstate New York, and Houppert, a 5th grade teacher, wanted to start a class book club last year, they knew they would have to think creatively to accommodate reading levels spanning 2nd to 6th grades.

Co-teaching can be done with the use of stations or team teaching. In station teaching, the teacher would have their own subject area to teach while students rotated between the teachers. In team teaching, the teachers would still have their own subject area to teach within a lecture but they would do it together at the same time in front of the class.

Having two teachers in the room co-teaching can be beneficial by using the model where one teaches and the other observes or assists. For example, one teacher would address the class while the other observes the class for evidence of learning or they assist individuals as needed during instruction.
