DEVELOPMENT OF TEAM BASED LEARNING- PBL TOOLS WITH THE ASSISTANCE OF WHATSAPP AND FACEBOOK MESSENGER

The Covid 19 pandemic has a major impact on all sectors of life including in the world of education. The implementation of PJJ (Distance Learning) requires new innovations in the development of learning devices so that learning continues to run well even though learning activities are carried out at home. The development model used in this research is the 4D Development model. The result of this study is that the learning device is said to be "valid" through a construct validity test. The resulting learning device is said to be practical based on the average percentage of learning implementation during 3 meetings by 95% and the percentage of teacher and learners' response results related to the use of learning devices in the online learning process by 98%-100% and 82%-86% on indicators. Concluded learning devices are developed quality and can be used as a new reference in the learning process. Keywords: Team Based Learning, Problem Based Learning (PBL), Learning Tools

DEVELOPMENT OF DISCOVERY LEARNING-ORIENTED PHYSICS E-MODULES FOR STUDENTS OF CLASS X MIPA CHAPTER WORK AND ENERGY

The purpose of this research is to develop teaching materials in the form of a Discovery Learning-oriented physics learning module that is valid and practical for students of class X SMA science program. This type of research uses Research and Development (R&D). The research subjects of class X MIPA 5 were 39 people. The research procedure used by the 4-D model is definition, design, development and dissemination. The research instrument is a questionnaire of initial analysis, validity, and practicality. Furthermore, the data were analyzed to see the validity and practicality of the E-module. E-module validation is assessed from the aspect of ease of use, time required, easy to interpret, and has the same equivalence. The results showed that the E-physics module was categorized as very valid with a percentage of 91.96%. Furthermore, the practicality of the E-module is assessed from the aspect of ease of use, time required, easy to interpret, and has the same equivalence with a percentage of 92.77%. Keywords: Discovery Learning, E-module physics

ANALYSIS OF GREENHOUSE EFFECT CONCEPT MASTERING ON PHYSICS EDUCATION STUDENTS FOR THE 2016 UNIVERSITY OF JEMBER

The greenhouse effect is the process by which radiation from a planet's atmosphere warms a planet's surface to a temperature higher than what it would be if there were no atmosphere. Catherine Gautier (2006) in a class shows that students are often unaware of their misunderstanding of their representations when compared to scientific representations. One of the factors that can influence misconceptions in students is an error in interpreting the meaning conveyed. This study aims to test the mastery of the concept of the greenhouse effect on students. The sample used in this study was 50 students of Physics Education class of 2016 at the University of Jember who were taking their fourth semester. Methods The research is carried out with quantitative methods. The method of collecting data is a questionnaire obtained from open questions (in the form of essays) posed to students of Physics Education class 2016 at the University of Jember, totaling 10 questions. Based on the results of data analysis, it can be concluded that there are students who have misconceptions about the greenhouse effect.

ENTREPRENEURSHIP-ORIENTED PROJECT-BASED LEARNING TO IMPROVE STUDENTS' ENTREPRENEURSHIP ATTITUDES

Science learning has potential in the nation's development efforts in terms of process. Applicative science materials can be used to develop the entrepreneurial spirit of students. However, the lack of student awareness in the application of science science has resulted in science education being only seen as science learning materials for junior high schools. Students lack the ability to have a scientific attitude that affects their entrepreneurial abilities. The purpose of this study is to determine the entrepreneurial ability of students by applying the PjBL learning model. This research is a quasi-experimental study with one group pretest-posttest design. The research population is the students of Science Education, Tidar University. Sampling by random method. The instrument used is a student entrepreneur response questionnaire. Data collection techniques through questionnaires. The results showed that the students' pretest results in the very low category were the highest at 43%. However, the posttest results showed progress with the highest percentage, namely the high category with a percentage of 38%. Thus, project-based learning (PjBL) has a good effect on students' interest in entrepreneurship

VALIDATION ANALYSIS OF CONTEXTUAL-BASED COMIC LEARNING MEDIA DEVELOPMENT ON TORQUE CONCEPT MATERIALS IN SMA

Lack of student interest in studying physics because in addition to lessons that are considered difficult, learning media are also still less attractive so that learning media are needed that can make students interested in a pleasant learning atmosphere that is supported by learning that connects material with applications that occur in everyday life such as contextual based physics comics. The purpose of this research is to produce a product in the form of contextual-based comic media on torsional concept material in high school. The analytical technique used is descriptive qualitative analysis to be able to describe the validation of the questionnaire from the validators of material experts and media experts. This study uses Research and Development (R&D) research with a 4-D model consisting of define, design, development, and dissemination stages. The research is limited due to time constraints so that it only reaches the development stage. The results of the study obtained a material validity value of 4.05 or 81% which was included in the very feasible category and the media validity value of 4.5 or 90% which was included in the very feasible category. From the results of the study, it can be concluded that the development of contextual-based comic learning media on torsional concept material in high school is very feasible to be used as a learning resource. Keywords: Validation, learning media, comic, and contextual

ANDROID-BASED LEARNING MEDIA DEVELOPMENT FOR CHAPTER 2D AND 3D ANIMATION

The Students of 2D and 3D Animation subjects class XI Multimedia SMK Negeri 1 Sijunjung have difficulty in understanding learning materials. Absence of learning media that support learners' learning outcomes in 2D and 3D Animation subjects makes it difficult for learners to understand the subject matter. This research aims to develop a valid and practical android-based learning medium on the subjects of 2D and 3D Animation. The research method used Research and Development (R&D) with ADDIE (Analyze-Design-Development-Implement-Evaluate) model. The results of the study are: (1) media validation results obtained with an average of 0.77 with the category "valid" (2) material validation results obtained with an average of 0.85 with the category "valid" (3) the practicality of teachers obtained with a percentage of 89% with the category "very practical" (4) the practical results of learners obtained with a percentage of 94% with the category "very pragmatic.

ASSURE MODEL WITH ICT-ENVIRONMENTAL SCIENTIFIC APPROACH TO IMPROVE CRITICAL THINKING ABILITY

This research is compiling and describing, among others; 1) The background of the development of the Assure model, 2) the main concept of the Assure model, 3) the concept of the Assure model with a scientific approach, ICT-Environment, 4) How to integrate the Assure model with a scientific approach, ICT-environment into the lesson plans. 5) the concept of critical thinking, 6) Description of the application of the Assure model with a scientific approach, ICT-environment to improve critical thinking skills in chemistry learning. Using the literature study methodology. The research finding is that the Assure model can be integrated with a scientific approach and then combined with Information Communication and Technology (ICT) which uses concrete examples from the environment to improve critical thinking skills in chemistry learning. In conclusion, the application of the Assure Model using a scientific approach -ICT - environment will provide effective learning for students to explore chemistry more broadly so as to increase critical thinking power.
