Abstract

Abstract : This study aims to develop Solubility and Solubility Constant Product (Ksp) module based on problem solving for Senior High School Students in 11th Grade Curriculum 2013 which is valid and practical. This type of research is research and development (R&D) which covering Define, Design, Develop, and Disseminate. The object of this research is module based on problem solving. The data collection instrument used are a validation sheet that given to three expert validators and user response questionnaire that given to three chemistry teachers and 20 Senior High School Students. Data analysis technique is by calculating the percentage score of validation and user response. The average score of the assessment by the validator team, i.e. self-instructional, self-contained, stand alone, adaptive, user friendly, IDEAL Problem Solving, pedagogic, and gradability aspects are 95,83%, 95,83%, 87,5%, 95,83%, 95%, 98,33%, 93,33%, dan 96,43%. Thus, the mean overall score of the solubility and Ksp module based on problem solving is 94,762% with ‘Valid’ category. The teacher’s average response to the module score os 91,667% with the croteria can be used without revision. The percentage of average score of student’s responses to developed module is 94% with the croteria can be used well. Based on the data analysis, it can be concluded that the module based on problem solving is valid and can be used well on subject of solubility and Ksp.Key Word : Module, Problem Solving, Solubility and Solubility Constant Product (Ksp).

Abstract: This is a classroom action research. This research is an attempt to improve student learning activities in chemistry on class XI IPA 5 of SMAN 9 Pekanbaru by applying cooperative model of Student Teams Achievement Division (STAD). Improved student learning activity is the activity of asking questions, submit answers or opinions, working on exersices and group discussion, quiz too. There were 36 students of XI IPA 5 SMAN 9 Pekanbaru involved in research that did in four cycles of learning. Each cycle consisted of one meetings through four stages of implementation: planning, action, observation, and reflection. Data collection techniques using observation and test. The result of action showed that activity percentage of students increased and reached the success indicator. Activity of student percentage in first cycle 55,20% with criteria enough, second cycle 62,15% with criteria good, three cycle 66,14% with criteria good and fourth cycle 73,43% with criteria good. The percentage of learning outcomes also increased and reached the success indicator. The average percentage in 1st, 2nd, 3rd, and 4th followed by 79,79&, 84,03%, 82,83%, and 99,03%. Based on the result obtained, it can be concluded that application cooperative model of STAD can to increase the activity and student learning outcomes.Keyword : Cooperative Model of STAD, Student Activities, Learning Outcomes Student
