Abstract

The Development of Students’ Discovery Learning Worksheet Based on Android in Buffer Solution. The objectives of this research were to develop and determine the feasibility of Android-based learning media and to describe its characteristics, teachers’ and students’ responses to the student worksheets discovery learning based on Android in buffer solution. This research used Borg and Gall research design and development which only focused on the first five stage. The data were analyzed using descriptive statistics analysis. The expert validation showed that the average percentage on content suitability aspect, construction and readability were 89,44%, 92,85% and 92,94% and considered as very high criteria consecutively. The teachers’ responses on suitability, construction and readability aspects were 92,59%, 93,96% and 94,51% and considered as very high criteria respectively. Therefore,students’ responses on readability and attractiveness were 96,03% and 98,05% and considered as very high criteria. Based on these results, the student worksheets based on Android generated by this research is valid and worthy as sources of learning.Keywords: learning media, discovery learning model, student worksheets, android, buffer solution.

Abstract

The purpose of this research was to describe the effectiveness of a problem solving learning model on electrolyte and non electrolyte solution material. The method used was a quasi-experiment with the matching only pretest-posttest control group design. The population on this research was all of the students from Senior High School Al-Azhar 3 Bandar Lampung in grade X IPA. The research sample was determined by purposive sampling technique, in order to obtain class X IPA 4 as the experimental class and X IPA 3 as the control class. The data analysis technique used is the difference test of two means using the t-test. The results showed that the n-gain mean of science process skills in the experimental class (0.67) was in the medium category; There is a significant difference in the average posttest score of science process skills between the experimental class and the control class. Thus, it can be concluded that the problem solving learning model on electrolyte and non-electrolyte solution material is effective for increasing students' science process skills. Keywords: electrolyte and non-electrolyte solutions, science process skills, problem solving learning models.
