Abstract

This research is research into the development of an inquiry-based learning model instrument which aims to obtain a suitable instrument for assessing learning tools. This research method uses ADDIE (Analysis, Design, Development, Implementation, Evaluation). In the initial stage of the research, data analysis was carried out regarding the needs of the model to be developed so that an instrument for assessing learning tools could be designed and continued with implementing it, then evaluating it to obtain the final results as to whether the development of an instrument for assessing learning tools was suitable for use. Furthermore, the learning tool assessment instrument obtained is used as a measuring tool to collect data on the aspects studied so as to produce learning tools that have high validity and reliable criteria for the lesson plans, worksheets, videos and PPTs that have been assessed. The test results obtained from the data at the feasibility test stage of the learning device assessment instrument were through a validity test using the Aiken's Value formula and a reliability test calculating the Cronbach's Alpha value in the learning device validation questionnaire assessment instrument. Testing the validity of the learning tool validation questionnaire assessment instrument obtained an average CVI (Content Value Index) value of 0.839 with high validity criteria and a reliability test by calculating Cronbach's Alpha value of 0.740 with reliable criteria. Testing the validity of the learning device assessment instrument, the average CVI value for the learning device assessment instrument was 0.808 with high validity criteria. The general conclusion obtained by the results of the validity test and reliability test has shown that the validation of the assessment of learning tool instruments in the development of inquiry-based models is stated to have high validity and reliable or trustworthy criteria used as a measuring tool for collecting data on the aspects studied.
