This study aims to determine the differences in learning outcomes and critical thinking ability of students who are taught by the model of Problem Based Learning using the media handout and power point. The population in this study were all students of class XI SMA Negeri 1 Berastagi. Sampling was done by random sampling. Then hypothesis testing is conducted using a two-party test of Independent Sample T-Test. To test the hypothesis I obtained results sig. 0,018 (sig. < 0,5) which means there is a significant difference in students' learning outcomes who are taught by the model of Problem Based Learning using the media handout compared learning outcomes of students who are taught by the model of Problem Based Learning using media power point on the material buffer solution. To test the hypothesis II result sig. 0,001 (sig. <0,5) which means there is a significant difference in students' critical thinking ability who are taught by the model of Problem Based Learning using the media handout than students' critical thinking ability who are taught by the model of Problem Based Learning using media power point on the material buffer solution.Keywords: Problem Based Learning, Handouts, Buffer Solution.

This study aims to determine learning outcomes using the Student Team Achievement Divisions (STAD) model assisted with macromedia flash compared to Discovery Learning assisted with macromedia flash on the reaction rate material. The study population was all students of class XI MIPA MAN 3 Medan. The sampling technique in this study is simple random sampling. The selected sample is Class XI MIPA 1 as an experimental class I which is treated with a Student Team Achievement Divisions (STAD) model assisted by macromedia flash and Class XI MIPA 3 as an experimental class II which is treated with a Discovery Learning model assisted by macromedia flash. This study uses test instruments that have been tested and are valid. Student learning outcomes data are first tested for normality and homogeneity, where the results obtained by both groups of samples are homogeneous and normally distributed. Hypothesis testing uses the Independent Sample T-Test, with the results of the research obtained a significance value of 0.047. Thus, there are significant differences in student learning outcomes taught using the Student Team Achievement Divisions (STAD) model with Discovery Learning assisted by macromedia flash with a result of 14% using the STAD model better than Discovery Learning.Keywords: Learning Outcomes, Student Collaboration, Student Team Achievement Divisions (STAD), Discovery Learning, Reaction Rate

The partners that are targeted by this service program are the Study Center Resource Centers (PSBG) Study Centers and Creative Parks located in Tebing tinggi city of North Sumatra Province. Based on observations and interviews with the PSBG administrators there are 5 problems faced by partners, including: (1) The teacher's ability to make teaching aids and catalogs is very low; (2) The use of IT contained in the CBD is very rare; (3) RPPs made by teachers have not included various learning models; and (4) The teacher has not been able to make a monthly PSBG magazine. Based on these problems, a number of solutions were offered, including: (1) training and mentoring to create learning media and their catalogs; (2) training and mentoring for making IT-based media; (3) training and mentoring to prepare lesson plans with various learning models; and (4) training and mentoring for the creation of the PSBG monthly magazine. Specific targets and outputs that will be produced are: (1) Catalog of learning media; (2) A collection of IT-based learning media; (3) Book collection of assessment rubrics. The method of implementing the service program will be carried out in a gradual, continuous and comprehensive manner carried out through clinical supervision methods in an effort to develop the capabilities and skills of managing and empowering the sustainability of the CBC.Keywords: Revitalization, Cluster Learning Center, Based on IT
