Abstract

Acid-base is one of the important materials in chemistry learning. Based on preliminary analysis, it is known that students have not properly understood the concept of acid-base. This study aims to develop an acid-base e-module, analyze its validity, practicality, and effectiveness on critical thinking skills. This research method is development research with the Plomp development model. The e-module was validated by 5 valitadors. The practicality test was conducted on 28 students and 3 teachers. The effectiveness of the e-module is seen from the increase in critical thinking test score from 57 students. Validity and practicality were analyzed using Aiken's V, while effectiveness was analyzed with N-Gain. The results showed that the developed e-module had a validity value of 0.89 with a valid category; a practicality value of 0.87 by students and 0.97 by teachers with a practical category. The effectiveness results show that the e-module has an effect on students' critical thinking skills, as evidenced by the N-Gain score of the experimental class of 0,7 with a fairly effective category while the N-Gain score of the control class is 0,4 with a less effective category. Thus, the developed e-module is declared valid, practical, and effective.

Abstract

This research aims to analyze the validity, practicality and effectiveness of the salt hydrolysis module based on problem based learning integrated with TPACK on students numeracy literacy skills. The development model used is the 4-D model. The module developed was validated by two lecturers and three chemistry teachers. The practicality testing of the module was carried out by three chemistry teachers and 32 SMA students. Testing the effectiveness of the module was carried out using a pre-experimental method with a non-equivalent control group design. The validity test was analyzed using the Aiken's V formula where content and construct validity were obtained respectively 0.91 and 0.92 with the valid category. The practicality test was analyzed using the Aiken's V formula where the practicality scores for teachers and students were obtained respectively 0.94 and 0.86 in the practical category. The module effectiveness test was analyzed using N-Gain where an N-Gain value of 0.76 was obtained in the high category. Based on the results of data analysis, it can be concluded that the salt hydrolysis module based on problem based learning integrated with TPACK developed is valid, practical and effective to improve the numeracy literacy skills of Phase F SMA students.

Abstract

design stages, this research only focuses on the development stage, namely the validity and practicality tests. The research instruments used were validation questionnaires and practicality questionnaires for teachers and students. The validity test was carried out by 5 expert teams and the practicality test was carried out on two chemistry teachers and 34 phase F students. The results of construct and content validity tests were obtained at 0.89 and 0.93 with valid categories. The results of the module's practicality test conducted by teachers and students amounted to 92.92% and 87.45% with a very practical category. The results showed that a valid and practical PBL-based reaction rate module integrated with SSI was produced for phase F students.
