Study Notes
Experimental Designs in Educational Research
- Experimental designs are used to establish cause-and-effect relationships between variables in educational research.
- They involve manipulating an independent variable and measuring its effect on a dependent variable.
Limitations of Research Designs
- Correlational research designs cannot determine cause and effect, as they only identify relationships between variables.
Quasi-Experimental Designs
- Quasi-experimental designs differ from experimental designs in that they lack random assignment of participants to treatment or control groups.
Sampling in Educational Research
- The best method to ensure a representative sample of the population of interest is through random sampling.
Evaluating Research Studies
- Three key elements of research studies that help determine which studies are worthy of consideration are: the research question, the methodology, and the interpretation of results.
Volunteer Bias
- Volunteer bias occurs when participants self-select into a study, potentially leading to an unrepresentative sample.
Scientific Research on Classroom Practices
- The primary purpose of scientific research on classroom practices is to inform instructional decisions and improve student learning outcomes.
Observational Measures
- Observational measures in educational research involve watching or viewing the behavior of individuals to collect data.
Quality of Research Articles
- The quality of research articles is determined by factors such as the study's methodology, data analysis, and the significance of the findings.
Educational Psychology
- Educational psychology is driven by the desire to understand how people learn and how to improve educational outcomes.
