A researcher designs an experiment to test how variables interact to influence how well children learn spelling words. The main purpose of the study was: Options: (a) Explanation (b) Influence (c) Description (d) Prediction ✅ Correct Option: (a) Explanation Explanation: Explanation in research focuses on identifying cause-and-effect relationships between variables. In this study, the researcher examines how different variables interact to affect spelling learning, which clearly aims to explain why and how learning outcomes occur. Experimental research is particularly suited for explanation because it allows control and manipulation of variables. The purpose is not merely to describe performance or predict results, but to understand the mechanisms influencing learning. Explanation helps improve teaching strategies by identifying effective instructional factors. Thus, the primary purpose of the study is explanation. 10 PPSC-Oriented Facts: 1. Explanation identifies causes. 2. Experiments test relationships. 3. Variables interact in learning. 4. Explanation improves instruction. 5. Control is key in experiments. 6. Teaching strategies depend on explanation. 7. Learning outcomes need analysis. 8. Explanation differs from description. 9. Scientific research seeks causes. 10. Educational improvement relies on explanation.
