Educational Experimental Research

Instructions

Please develop a true experiment and label the primary components related to experimental research. Be sure that your experiment has a manipulation and a control. Be sure to pay special attention to the steps in the process and potential challenges as discussed in the text. Also, discuss the possible threats to internal and external validity, explaining how you might attempt to account for any (or all) that might apply to your study. Be sure to define/explain the threats that apply to your study. In summary, please do the following:1) Develop an experiment (Education Related)2) Label all the primary components, using proper terminology3) Name and describe the threats to internal and external validity4) Share how you might attempt to account for each of these threats as it pertains to your study

Answer

1. Develop an experiment (Education Related)The research experiment would seek to analyze and compare the mean achievement scores in physics subject using enriched demonstration and lectures as educational approaches. In this experiment, data collection will involve the use of physics achievement test to determine the mean achievement scores between the two groups of students (experimental group subjected to enriched demonstration while control group subjected to lectures). Data analysis will involve the use of Analysis of Covariance (ANCOVA) to test the major hypothesis. This analysis will seek to answer if there is a significant difference between mean student achievements between the groups subjected to the two treatments. The control group will involve the students subjected to lecture...
