Abstract

The research aims to find out whether the science process skills of students who are taught with inquiry training model better than direct instruction learning, to know whether the science process skills of students who have the ability to think critically above the average is better than students who have the ability to think critically below average, to find out whether there is an interaction between the learning model between the learning model and the critical thinking ability in improving the students' science process skills. This research is a quasi experimental research with two group pretest-posttest design design. The study population is all students of class XI SMA Negeri 1 Pintupohan semester II academic year 2016/2017. Sample in this research is taken by cluster random class, that is as much as 2 class which amount 60 people. Class X-1 as an experimental class taught with inquiry training model consists of 30 students, while X-2 class as control class is taught by direct instruction learning consist of 30 students. The instrument of this research consists of two types of science process skill instruments consisting of 10 questions in the form of test essay, and students' critical thinking ability instrument consists of 5 questions in the form of test essay. The resulting data, analyzed by using two path Anava and H0 accepted means there is no interaction between instructional model inquiry training and direct instruction learning with students 'critical thinking skills to improve students' science process skills.

Abstract

This study aims to determine: the effectiveness of the development of problem based learning model based on Batak culture implemented in learning tools developed, improvement of problem solving skills of physics that dibelajarkan with model based learning based on batak culture. Type of research is development (development of research) by using model of development of Thiagaraian, Semmel and Semmel that is 4-D model (four D Model). The sample in the study is one class X of all classes of MIA X present in the research site. The instrument used is a problem-solving test. Data in the study were analyzed using N-gani. The results showed that: the effectiveness of learning tools through the model based learning based on Batak culture in improving the ability of problem solving physics has been able to be said to be effective for use in learning, there is improvement of problem solving problems of physics students using learning tools based on culture based Batak on measurement material

Abstract

This study aims to describe the validity, practicality and effectiveness through Batak culture based cooperative learning models and to know the improvement of generic science skills and student’s teamwork by applying learning tools through Batak culture based cooperative learning models. This research is a Research and Development (R & D) using the 4-D model that includes define, design, develop, and disseminate.  This research was conducted at the school of SMA Negeri 1 Tambangan with a population of 21 students in class X MIA I. Instruments and techniques of data collection using learning device validation sheets, namely validation sheets of lesson plan (RPP), validation sheets for student worksheets (LKS), validation sheets for generic science skills instruments and student’s teamwork, sheets of learning practicality assessment, learning effectiveness sheets, learning activity instruments, instruments generic science skills and student’s teamwork questionnaires. Improved generic science skills and  student’s teamwork using analysis with N-gain test. The results showed that the learning materials through Batak culture based cooperative learning models had met the criteria of valid, practical and effective. Students generic science skills increase to the medium category and there is an increase in student’s teamwork with the medium category
