This study aimed to determine the validation of Andro-web comics on Work and Energy topic. To achieve the objective, this study was designed referring to ADDIE model, i.e, Analysis, Design, Development or Production, Implementation or Deliver, and Evaluations. The Andro-web comics could be accessed using a digital comic application, Webtoon. It is downloadable in Play store or App store. The Andro-web comics is compatible with all devices including mobile devices (phone, tablet, iPod, PDA, and smartphone) and PC/Mac. Based on the expert judgment, the Andro-web comics is suitable for learning. The Instructional-Based Andro-Web Comics is alternative instructional materials for teachers to attract students’ attention and help them studying easily and practically as it provides an interesting illustration with simple language. It could also be used wherever and whenever without teacher’s guidance. Both teachers and students could communicate on the comment column which is available in the application without time and place limitation.

This research aims to determine the validity of comic-based module andro-web on the subject of an ideal gas and increased capacity problem-solving physics students after using comic-based module andro-web on the subject an ideal gas. The research uses the design nieveen model of development. In the assessment phase, the module then tried out on 30 grade XI science 2 Jenggawah Senior High School. The instruments of product quality are an instrument validation and instrument increased capacity problem solving of physics students about pre-test and post-test completed by using 5 indicators problem-solving. The average score validation comic-based module andro-web by validator 81,7 % with valid category. The score validation by user validator obtained score 93,3 % with a very valid category. Besides, increased capacity problem-solving physics students a score was obtained for 47,3 % in by test n-gain medium category. Thus, it was stated that comic-based module andro-web can be used in teaching material XI science class and will raise the ability problem-solving physics students on the subject of an ideal gas.

Abstract

The application of problem based learning in the classroom often experiences obstacles, primarily to teach high-level thinking skills, such as critical thinking skills. To overcome these obstacles, in this study we tried the use of peer tutors to guide their friends in a collaborative group when solving problems. This study aims to describe the impact of peer tutoring in problem-based learning on the critical thinking skills of high school physics students. This type of research is a quasi-experimental study with a pretest-posttest control group design. The sample of this research is class X MIPA 3 and X MIPA 4 SMAN 4 Jember. One class was given treatment using problem-based learning accompanied by peer tutoring, while one other class only used problem-based learning. Data about critical thinking skills were obtained from the posttest at the end of learning which was then analyzed using the Independent Sample T-test on SPSS 23. The statistical test results stated that there were differences between the average values of the experimental class and the control class. Thus, it is concluded that peer tutoring in the problem-based learning model has a significant effect on critical thinking skills. The essential aspect of thinking skills with the highest value lies in interpreting skills.

This research describes the subject of elasticity using the Project Based Learning (PjBL) model with the STEM approach to improve students activeness. This research implemented for XI MIPA 5 class at 2 Jember Senior High School in the 2019/2020 academic year during August until September 2019. Data were collected through observation and interviews. This data were analyzed descriptively. The results showed that the Project Based Learning model with the STEM (Sains, Technology, Engineering, and Mathematics) approach could increase of students activeness for XI MIPA 5 class at 2 Jember Senior High School of elasticity material.
