In the realm of K12 education, research, evaluation, and educational inequality are intertwined concepts that play crucial roles in shaping the educational landscape. Research serves as the foundation for understanding educational issues, while evaluation helps to determine the effectiveness of educational initiatives. Together, they can be powerful tools in combating educational inequality.

The Distinctive Roles of Research and Evaluation
Research in K12 education is about exploring new knowledge, theories, and practices. It involves systematic investigations to answer questions like why some students perform better than others or what teaching methods are most effective. For example, research might delve into the impact of different curriculum designs on student learning outcomes. According to ERIC (Education Resources Information Center), educational research can provide insights into various factors affecting education, such as socioeconomic status and family background. On the other hand, evaluation is more about assessing the worth, effectiveness, or quality of an educational program, policy, or practice. It helps educators determine whether a particular intervention is achieving its intended goals.

How Research and Evaluation Connect
Research and evaluation are closely related. Research findings often inform the development of evaluation criteria. For instance, if research shows that student engagement is a key factor in academic success, then evaluation measures can be designed to assess the level of student engagement in a classroom. In addition, evaluation results can guide further research. If an evaluation reveals unexpected outcomes of an educational program, it can spark new research questions. As stated by The Handbook of Educational Evaluation, this cycle of research and evaluation is essential for continuous improvement in education.
Both research and evaluation are essential in the fight against educational inequality. Research can identify the root causes of inequality, such as disparities in access to resources or differences in teaching quality across schools. Evaluation can then be used to test interventions aimed at reducing these inequalities. By working together, research and evaluation can help educators develop more effective strategies to ensure that all students, regardless of their background, have equal opportunities to succeed in education.
