Abstract

Abstract: The implementation of problem based learning to increase student’s learning outcomes is explained. This research aimed to determine the implementation of problem based learning to improve the student outcomes in senior high school (SHS) in studying chemistry. This research is conducted in SMKN 2 Palembang which the subject of research is students in tenth grade. The populations are class X TKJ 3, while the subjects were 34 students. The research is conducted by teaching students with problem based learning model followed by evaluation test in the end of each cyle to obtain learning outcomes. The results showed that the average value of Evaluation-Test for first cycle is 67,21 with the second cycle is 83,14.. The students total average of the achievement showed that the percent affectivity of problem based learning implementation showed there is significant differences between teaching by using problem based learning. So, we obtained that teaching chemistry subject by using problem based learning model is quite effective. Keywords: problem based learning, learning outcomes, elemental chemistry, classroom action research.

Abstract: The Implementation of Problem Based Learning Model to Increase Student Learning Outcomes of Chemistry Subject in Tenth Grade of SMKN 2 Palembang. This Research aimed to determine the implementation of Problem Based Learning model to improve the student learning outcomes using Problem Based Learning (PBL) model. Research was done by two cycle and every cycle conducted two meetings with including planning stage, implementation, observation, and reflection. This research is conducted in SMKN 2 Palembang which the subject of research si students in X classs. The Populations is class X TKR 2, the subjects were 34 students. The instrument used observation sheet and the learning outcomes test. The result showed that of students learning outcomes is increased with the students average value of evaluation test for first cycle si 74 with the clasical percentage value is 70.59% and students average value of evaluation test for second cycle is 80 and the classical percentage value is 80. Depend on the result of the research showed that the implementation of Problem Based Learning model showed there is significant differences by using PBL. So, we can obtained that the teaching chemistry by using PBL is quite effective.Keywords: problem based learning, learning model, learning outcomes

Abstract

Abstract: This class action research aims to improve the learning outcomes of chemistry on students Grade X Geomatics 1 SMK Negeri 2 Palembang by implementing the Problem Based Learning model. This dtudy is conducted in two cycles, each cycle consist of two meetings. The data are obtained from using the observation sheet and students’ learning outcomes test which is given every meeting. The improvement of students’ learning outcomes can be observed from the average number of students’ learning outcomes before treatment (T0) in the amount of 68,97 with 38,23% learning completeness. The improvement happens on cycle I (T1) becomes 74,93 with the mastery 52,94% and on cycle II (T2) it increased to 85,79 with 88,23 % learning completeness. The application of Problem Based Learning model can improve learning outcomes. Keywords: class action research, problem based learning model, students’ learning outcomes of chemistry

Abstract

Abstract: Implementation of Guided Discovery Learning to Improve Chemistry Learning Outcomes of class X TBSM 1 at SMK Negeri 2 Palembang. The study is aimed to enhance the learning outcomes of chemistry on students class X TBSM 1 by implementing the Guided Discovery learning model. This study is conducted in two cycles; each cycle consists of two meetings. The data are obtained from using the observation sheet and an instrument of students’ learning outcomes test which is given every meeting. The enhancement of students’ learning outcomes can be observed from the average number of students’ learning outcomes before treatment (T0) in the amount of 62,86 with the mastery learning in the amount of 41,67%. The enhancement happens on cycle I (T1) becomes 68,72 with the mastery learning in the amount of 44,44% and on cycle II (T2) enhances into 87,45% with the mastery learning in the amount of 86,11%. Based on the result it is concluded that students’ learning outcomes achieve the mastery learning classically through the implementation of guided discovery learning model and students’ activities which happen to be enhancing as well.  Keywords: class treatment study, guided discovery model, students’ learning outcomes of chemistry.

Abstract

Abstract: The Increase Of Study Chemistry Through Implementation of Cooperative Learning Model Type STAD in Class X TITL 4 SMKN 2 Palembang. Classroom Action Research (PTK) aims to know the improvements studied chemistry students using a learning model of Student Teams Achievement division (STAD). The research was conducted in the class X SMK Negeri 2 Palembang and the object at students of class X TITL 4, amounting to 34 students. The research which is implemented in two cycles. The data obtained from each cycle later in the analysis to know of any amprovement in the learning process and as a corrections to proceed to the next cycle. Data obtained using sheets of observation and instrument test student learning outcomes. Improved student learning outcomes can be seen from using class average and percent students classical. In the first cycle the average score of students is 66.72 with the percentage of students classical is 41.18%. in the second cycle, there is an increase score in student learning by 78.74 with the percentage classical student to 84.84% Keywords: classroom action research,  learning  model  of  stad,  student  learning outcomes.
