In summary, a literature review is a key process in research, as it allows for understanding the current state of knowledge on a topic, identifying gaps, and justifying new studies. Additionally, it helps select the best strategies and methodological approaches based on previous evidence.

A literature review follows a systematic process to ensure that the information is analyzed effectively and efficiently. This structured approach helps researchers locate relevant sources, refine their research focus, and build a strong theoretical foundation for their study. The process includes the following steps:

1. Determine the search focus

A specific topic must be defined, avoiding it being too broad or too narrow. For example, investigating "metacognition in Chinese immigrant children" might be too restrictive, so it is recommended to start with more general terms and adjust them based on the obtained results.

2. Decide what to include and exclude

Once the topic has been defined, selection criteria must be established. This ensures that only studies relevant to researchers on the topic are considered. Researchers may decide to include studies with characteristics such as age, educational level, the study contexts public schools, private institutions, rural schools or the range of publication dates such as studies from the last 10 years. In this way the search will filter and find hundreds of results, applying these criteria helps to filter out extraneous studies and make the review process more feasible.

3. Translate the topic into key terms

Effective database searches require identifying keywords related to the research topic. These terms should be broad enough to retrieve sufficient results but specific enough to remain relevant. For example, in a study about metacognition in immigrant children, relevant keywords could include "metacognition," "bilingual education," "cognitive development," and "immigrant students." Using synonyms and alternative phrasing (e.g., "self-regulated learning" instead of "metacognition") can improve search results.

4. Conduct the database search

Researchers can search for sources in electronic databases like ERIC, PsycINFO, and JSTOR, which provide access to peer-reviewed academic articles. Searching manually through reference lists in existing research papers can also uncover additional relevant sources. Keeping track of sources, using citation management tools like Zotero or Mendeley, helps organize findings efficiently.

5. Analyze and select the results

After collecting the sources, as researchers, we must review the abstracts and references of the articles to determine their relevance. If an initial search yields few results, it may be necessary to check the search terms or use alternative keywords. Additionally, we can categorize the sources based on their topics, methodologies, or findings to facilitate the synthesis of information in the literature review.

According to the chapter, a literature review can serve different purposes, including:

A literature review serves multiple purposes in academic and professional research. It allows researchers to build upon existing knowledge, justify new studies, and refine their methodologies.

1. Discover what works
One of the main goals of a literature review is to identify effective practices or strategies within a specific field. As the text mentions, educators often look for innovative teaching methods in workshops, online sources, or peer discussions. However, reviewing academic literature ensures that these practices are backed by empirical evidence, helping professionals make informed decisions based on proven methodologies. For example, a teacher considering project-based learning can review studies that analyze its impact on student engagement and academic performance.

2. Investigate a topic, problem, or question of interest
Conducting a literature review enables a deeper understanding of a subject of academic or professional relevance. For instance, a teacher aiming to enhance their instructional approach may explore research on cooperative learning, flipped classrooms, or gamification to evaluate their effectiveness in different educational settings. By analyzing previous studies, researchers can compare outcomes and identify best practices for their own contexts.

3. Identify new areas of study
Reviewing existing literature can reveal research gaps that need further exploration. The text highlights that while numerous studies discuss learning strategies broadly, there may be limited research on their specific impact on state competency exams. Recognizing such gaps helps scholars propose new investigations that contribute valuable insights to the field. Additionally, identifying under-researched populations, such as students with special educational needs, can guide researchers toward more inclusive and diverse studies.

4. Justify a study or provide background information
In academic research, particularly in theses and dissertations, a literature review plays a crucial role in establishing the significance of a study. By analyzing previous work, researchers can justify why their study is necessary and how it builds upon existing knowledge. For example, if multiple studies suggest that early bilingual education enhances cognitive development but lack longitudinal data, a researcher could justify a new study that tracks students’ progress over several years.

5. Analyze research methodology
A literature review does not only examine past research findings but also evaluates how those studies were conducted. This allows researchers to identify methodological strengths and weaknesses, which can inform the design of new research. For example, if most studies on student motivation use quantitative surveys, a researcher might consider a qualitative approach, such as interviews, to gain deeper insights into students' personal experiences. By understanding different research methodologies, scholars can select the most appropriate approach for their own studies.

A literature review is a process of collection, analysis and synthesis of information from various sources of study, research and academic texts on a particular topic. Its purpose is to provide a clear and substantiated view of existing knowledge in a field of study. According to the text, this process provides insight into what has been previously researched and what areas need further exploration. It also helps to justify new research by analyzing gaps in research on the topic. In addition, a literature review critically evaluates sources, comparing different viewpoints and methodologies. This process is essential not only to contextualize a study, but also to guide the methodology.
