Abstract

This research aims to (1) develop valid questions to measure Higher Order Thinking Skills (HOTS) for chemical teacher candidates on ionic equilibrium in solution topic (2) evaluate chemical teacher candidates’ HOTS on ionic equilibrium in solution topic. Research is a development research type formative research that consist of analyzing, designing, evaluating, and revising. All data are analyzed using descriptive technique. Subject in this research are chemical teacher candidates of University of Riau Chemical Education Study Program. The results of this research are: (1) four of valid HOTS open-ended questions on ionic equilibrium in solution topic. (2) value of chemical teacher candidates’ HOTS on ionic equilibrium in solution topic is 33.18 which put in medium category.

Abstract

This study was conducted in an effort to improve learning outcomes and learning motivation. The population in this study were students of Chemistry Education, University of Riau. The Samples of this research is fifth semester students. Class experiments using problem-based e-learning model, while the control class using classical learning. To test research hypothesis on difference learning motivation and improved learning outcomes using independent sample T-test SPSS-20. To Test research hypothesis on Correlations between students motivation in learning and learning outcomes using Correlations SPSS-20. The result showed that : 1) there was a significant difference in motivation and learning outcomes of students who are taught using a problem-based e-learning model, than students who are taught using classical learning; 2) there was no correlation learning motivation and learning outcomes of students who are taught by classical learning; 3) there was correlation between motivation to learn the results of student learning is taught by Problem-Based E-Learning Model.

Abstract

Research on the development of comic-based student activity worksheets (LKPD) with a 4C approach (Critical Thinking, Collaboration, Creativity and Communication) on chemical equilibrium material for high school is an innovation in the development of teaching materials in order to achieve the demands of 21st century learning that facilitates and inspire students to be able to think critically, communicatively, creatively, innovatively, and collaboratively. The study was designed using research and development design (R & D) with a 4-D development model. The validation sheet and user response questionnaire are research instruments designed and then analyzed and produce data in the form of assessment and suggestions by the validator team, teacher respondents and students. Feasibility aspects of content, language, presentation, graphics, and characteristics of comics with a 4C approach with an overall percentage score of 93% by the material validator. The results of the percentage of users by teachers are 95% and the percentage of students is 88% with very good criteria. Based on the data analysis, it can be concluded that student activities worksheets based on comics with a 4C approach that produced is valid and can be used on Senior High School on chemical equilibrium material.Keywords:Chemical equilibrium; student activities sheet based comics with 4C approach; 4-D development model
