Abstract

Socialization and training of the use of learning media based on learning management system (LMS) with moodle for junior high school teachers at Methodist 8 Medan aims to improve teachers' knowledge and skills in integrating Information Technology and Communication (ICT) into interactive, interesting and fun online learning. Moodle is a software application produced for dynamic learning activities based on technology, internet and websites. The methods that used for implementing this Community Partnership Program are socialization and training which begin with preliminary observations, analysis of learning problems and the needs of teachers and students. The next stage is the preparation of activities both from the partners and the team. The third and fourth stages are socialization and training on the use of learning media based on LMS by using the Moodle features. The result of this partnership program is that teaching materials such as power point presentation, learning videos, assignments and quizzes/student worksheets have been created and uploaded by utilizing the features in Moodle.

Abstract

The measure  of success in education is not only assesed on the cognitive side, but also on the character side. Every students must have characters that adheres to the noble values of Indonesia. This  research aims to know applied Problem Based Learning (PBL) model assisted by computer simulation with the increase of students character. This research used quasi experiment methode. The subject of this research involved three groups with each experimental group-1 that applying PBL assisted by computer simulation, the experimental group-2 applying PBL and the control group applying conventional models. The instrument of this study was a obeservation sheets and a questionnairies that measured student’s character.  The character aspects that measured in this research were self-convidence, curiosity, planned, initiative, integrity, perseverance, problem solving, and teamwork. The character’s data analyzed with gain Test (N-gain). The increase percentage of N-gain of student’s character in experiment group 1 and experiment group 2 were 34% and 32%  and respectively in medium category, but in control group, the increase was 12% , in the low category. The highest percentage increase in character of the experimental group 1 and experiment group 2 is the curiosity and the highest percentage increase in character of the control grou percentage increase in character of the is perseverance. Based on the results of the test, the application of pbl assisted by computer simulation is effective in improving student characters.

Abstract

This study aims to find out how the improvement of PPP and concept comprehension on students who are taught using guided inquiry learning model with conventional learning, whether the improvement of the KPS and the conceptual understanding of students using guided inquiry is better than conventional, whether the guided inquiry learning model influences the PPP and the students' understanding of the physics learning process and how the relationship between the students' KPS and the students' understanding of the concept. This research is a quasi experimental research with pretest-posttest experimental design group design design. The population is class X SMK Negeri 1 Stabat with a sample of two classes selected by random sampling. Data retrieval uses an instrument test of process science skills and concept comprehension. The results of the research for the increase of PPP of the two classes obtained pretest 42,13 and 42,86, while postes 79,66 and 55,06. The results of the research to increase the understanding of the concept of the two classes obtained pretes 40.83 and 33.33, while postes 79.00 and 58.83. The average yield of PPP increase using guided inquiry learning model is 0.64 and uses conventional learning 0.25. The mean improvement in conceptual understanding using guided inquiry learning model was obtained 0.68 and using conventional learning 0.38. The result of pearson correlation (r) is obtained> 0.05 ie 0.37.

Abstract

The purpose of this study was to determine the increase of students' critical thinking skills in learning by using Student Worksheets (LKS) assisted by computer simulations. The worksheet used was problem based and contained questions that explore critical thinking skills. This type of research was a quasi experimental of two groups pretest-posttest design. The population of this study was all students of class X Semester I of SMA Negeri 9 Medan, which consisted of seven classes with the number of students was 243 students. The participants of this study consisted of 2 classes which used cluster random sampling technique. The first class was class of X MIA 2, 36 students, as an experimental which was treated by using student worksheets problem-based assisted by computer simulation. The second class was class X MIA 3, 32 students, as a control class which was treated by conventional learning using. The instrument used was a critical thinking test of 10 questions in the form of problem-based description. Based on the results of different tests, this study obtained significant differences on students 'critical thinking skills by using problem-based worksheets assisted by computer simulations. In other words the implementation of learning by using problem-based student worksheets was better in increasing students' critical thinking skills than conventional learning. Percentage increase in N-gain of critical thinking experimental class 64% and control class 43%, respectively - medium category.

Abstract

Project based learning model (PjBL) is a model that is designed to train students to make plans and produce products that can solve problems in the surrounding environment. The PjBL model has five phases, there are (1) finding ideas, (2) designing the project, (3) compiling the project, (4) implementing the project, and (5) evaluating the project. The purpose of this study is to determine students ‘critical thinking skills and improve student’s critical thinking skills in learning physics through the PjBL model. The design in this study used one group pre-test post-test design on 60 students in Senior High School State of 12 Medan (SMA Negeri 12 Medan) at academic year 2019/2020. The instrument of students’ critical thinking skills uses 7 essay tests using indicators by Ennis, namely: (1) elementary clarification, (2) basic support, (3) inferring, (4) advanced clarification, and (5) strategy and tactic. Analysis of the data used is N-gain. The results of this study are students’ critical thinking skills in the medium category. And the improvement of students’ critical thinking skills is also in the medium category
