Improvement of Model Student Learning Through The Content of Solutions Guided Discovery Buffer

Abstract

Difficulties in learning chemistry for this still dwell on the difficulty in delivering of material that is abstract and microscopical. Lack of student understanding of abstract concepts of chemistry led to higher student outcomes on algorithmic aspects rather than its conceptual aspect. The study was to observe at student learning and trying to improve learning results in the subject matter of the buffer solution that it includes abstract concepts and contextually closely connected with algorithmic. The subject is a 21 pupils in class XI IPA 1 SMA Muhammadiyah Banjarmasin. This study aims to determine the increase (1) the activities of teacher, (2) the activity of students, (3) learning outcomes, and (4) the students' responses. The study design was a Class Action Research (CAR) and the study finished after reaching classical completeness in the second cycle to the research stages of planning, action, observation and reflection. The research instrument is a test and non-test. Data were analyzed by using quantitative descriptive analysis. The results showed that an increase in the sector (1) the teacher's activities is 7.68%, (2) the activity of students is 11.08%, (3) cognitive achievement of students is 33.33%, 11.00% process skills, psychomotor learning outcomes is 11.20%, affective learning outcomes by 30.01%, and (4) the response of students in the learning process guided discovery aided macromedia flash showed positive results with the percentage of 80.95%. The other findings are students easier in solving algorithmic problems than students completing the conceptual thus corroborates previous studies. Keywords:learning
