Pengembangan Model Pdeode-Web Dalam Blended Learning Pada Materi Sistem Pencernaan Untuk Meningkatkan Keterampilan Berpikir Kritis Siswa Kelas XI SMA
This study aims to determine the quality of the PDEODE-WEB model in blended learning on the digestive system material developed in terms of validity and practicality, as well as to see the effect of the PDEODE-WEB model in blended learning on digestive system material on critical thinking skills of high school students.
This research consists of two stages, namely the first stage of model development using Research & Development through the 4D approach in the FKIP UR Masters Program, the second stage of the experiment at SMAN 4 Pekanbaru. The model validation stage involved 4 subjects (1 media expert, 1 material expert and 2 pedagogic experts). Feasibility assessment by experts using a validation sheet. The practicality test phase involved 5 master students of Riau University majoring in biology and the limited trial involved 34 students. Assessment of the practicality of the model uses a questionnaire response. Data analysis used descriptive analysis assisted by Microsoft Office Excel 2010. The experimental stage was to see the effect of the PDEODE-WEB model in Blended Learning that was developed on students' critical thinking skills. The experimental stage involved class XI IPA5 as the experimental class and class XI IPA2 as the control class. Assessment of critical thinking skills which consists of 5 indicators, namely providing simple explanations, building basic skills, concluding, building advanced skills and managing strategies and tactics using pretest and posttest. Data analysis using the help of IBM SPSS Statistics 25 software. The results of the model development research show that the quality of the content validation is very suitable (3.66) and the quality of the construct validation is very good (4.25), while the quality of simulation is good ( 81,47) and practicality testing is very practical (88,75). This means that the PDEODE-WEB model is valid with a significant value
