A Development of E-Learning Chemistry Based on Project Based Learning on Buffer Solution Using Then Flipped Classroom Approach in Class XI SMA/MA

Abstract

Abstract—This development research aims to produce a development product in the form of E learning based on Project Based Learning (PPA) with a valid Flipped Classroom approach in SMA / MA. This study uses a 4-D model development research design which includes defining, designing, developing and distributing. The product validity test was carried out by collecting data from three validators (high school chemistry teachers) using an instrument in the form of a validation questionnaire. Based on the qualitative descriptive analysis using the formula "Aiken, the results for construct validation are 0.86 and content validation is 0.86. Based on the results and discussion, it is concluded that E-learning based on Project Based Learning (PPA) with the Flipped Classroom approach in SMA / MA that is valid is categorized as valid.

Validity and Practicality of Colloid E-Learning Content Based on Individual Rotation Guided Inquiry for Senior High School

“…http://www.jhice.ppj.unp.ac.id/ Asda, Viola et al [24,25,26]. This validation test was carried out by 4 chemistry teachers based on expert opinions (judgment opinions) with a minimum number of 2 validators [27]. This evaluation data is processed according to the Aiken's V formula.…”

“…This test was carried out by 3 chemistry teachers and 10 students. The elearning that is made must also have high learning flexibility (can be used repeatedly) for student Guided Inquiry for Senior High School ISSN : 2809-6916 JHICE Journal needs in the learning process [27]. The results of the practicality test can be seen in Figure 9.…”
