WestEd's research draws on various methods and sources to address key education and human development issues. From experimental to case studies, our research is rigorous and practical. We pride ourselves on our track record connecting evidence-based research to policy and practice.
In addition to the following four areas of WestEd research, check out the research-focused issue of our R&D Alert newsletter (Vol. 9, No. 2, published in 2008), which begins with a Q&A on the growing importance of education research and includes articles describing examples of WestEd-led research.
Experimental Studies
When we want to know the impact of an intervention, we conduct randomized controlled trials, also known as experimental studies.
Our researchers create a random sample from a population of interest, randomly assign subjects to treatment and control conditions, and minimize biases that might influence the validity of the results. Our statisticians and educators then analyze the data that will be useful to the field.
Quasi-Experimental Studies
When a randomized experimental design is not feasible or ethical, we conduct a quasi-experimental study to estimate the impact of an intervention.
Employing methods such as interrupted time-series and regression-discontinuity designs, our statisticians collect and analyze the data, and interpret the results. We present the findings to key audiences, including policymakers, to improve outcomes locally and nationwide.
Case Studies
When we need a holistic understanding of a program or policy, WestEd prepares a case study to answer the questions being asked and that is appropriate for the context.
Our researchers identify patterns and themes in the data, conduct cross comparison analyses, and use multiple sources of evidence such as documentation, questionnaires, interviews, and observation to sharpen the understanding of what is – or is not – working and why.
Survey Research
When we want to collect large amounts of information about people's knowledge, experiences, and attitudes, we conduct a survey.
Our researchers develop valid survey instruments, administer the surveys (via mail, telephone, or online), and collect, process, and analyze the data. WestEd disseminates the results, influencing both policy and practice.
