Development of Physics Teaching Media Using Speed Sensors as Speed Analysis in Realtime Based on Arduino to Remind Students' Problem Solving Abilities
Get PDFLearning about motion material such as straight-motion changes irregularly requires learning aids to analyze more deeply about speed. The problem that often occurs in learning motion material is that this material is only conveyed in the form of theory, has not touched the psychomotor domain from theory to practice. The concept of initial velocity and final velocity on the Irregularly Changing Straight Motion concept will be challenging to understand when dealing with applicable problems. Therefore we need learning aids to understand more integrally between theory and practice in analyzing speed by using a speed sensor (speed sensor). The speed sensor is used as an analysis of the real rate or travel time of Arduino-based objects. This study aims to develop physics teaching media using speed sensors as a realtime analysis based on Arduino. This research is a research & development (R&D) research using the Addie development model. The development stage of teaching aids consists of four stages, namely the analysis phase to analyze the needs of students and the components needed based on needs analysis, the design stage as a design stage based on needs analysis, the development stage is the stage of validating tools that have been designed by Ahlia Media and designing based on input by media experts..The results showed that the developed media produced expert validation values or the feasibility of the media with a category suitable for use in learning. The trial results show the learning media can increase the ability of problem solving by 2.2%

Data analysis results show that the ability of multi-representation in solving physics problems on Newton's law material about the force of gravity in the high category. The number of mathematical representations of 100%, image representation of 10%, then in the medium type only uses a mathematical description of 100% and in the low category using a mathematical representation of 100% and a verbal representation of 40%
Regression of Science Process Skills On Critical Thinking Skills In Two Junior High Schools In Jambi City
Get PDFThis study aims to look at the effect of science process skills on Jambi City Junior High School students' critical thinking ability on the density and reflection of the material in the mirror. This research method used was mixed method, while the design used was sequential explanatory. The study was conducted at Adhyaksa 1 Junior High School in Jambi City and Al-Jauharen Islamic junior high school in Jambi. The sampling technique used was cluster sampling, so that the sample of this study amounted to 58 students. The data collection instrument consisted of an observation sheet of science process skills, a test of critical thinking skills, and an interview. Data were analyzed using descriptive statistics and inferential statistics. Based on the results of the linear regression test that has been carried out, the t value is greater than the t table, it can be said that there is a significant influence between science process skills and critical thinking skills on the density material and the reflection on the mirror. Students who have low process skills will tend to have low critical thinking skills. Low science process skills and students' thinking abilities lead to low student learning outcomes
School Physics Assistance Learning using the TAI (Team Assisted Individualization) Model: Analysis of Student Evaluation Capabilities
Get PDFThe ability of prospective teacher students obtained in lectures needs to be developed to be applied in learning in schools. One of them is by applying the TAI learning model. The application of the TAI (Team AssistedIndividualization) learning model is implemented to analyze the student's evaluation ability in the implementation of school assistance and and to add to the experience of students in the real field. This effort was carried out with four stages of TAI namely Teams, Placement Tests, Student Creative, and Teaching Group. At each stage of the TAI model, students provide a description and analysis in the form of activity reports and presentations. The research conducted is a description of collaborating with experimental research, one-shot case study research on students of physics level 5 and data collection techniques with observation and interviews.The results showed that students had the highest ability to evaluate the ability to provide solutions to the obstacles found in partner schools and the lowest ability to find a settlement procedure that was suitable for the scope of the implementation of school assistance
Problem-Based Learning Approach with Supported Interactive Multimedia in Physics Learning: Its Effects on Critical Thinking Abilty
Get PDFIn this research, interactive multimedia on dynamic electricity concepts was developed and tested. The purpose of this research was to analyze the feasibility and the effectiveness of interactive multimedia through a problem-based learning approach to students’ critical thinking ability. The research and development (R & D) had three stages: preliminary study, development, and field testing. The field testing was a quasi-experiment with a pretest and posttest control group design. The research subjects consisted of four lecturers as expert validators, two teachers and two groups of 72 students in a senior high school in Batang Regency, Central Java. Data were gathered by using questionnaires, observation, interviews, and written test. The results of the Normalized-gain test were 61.79 for the experiment group and 49.91 for the control group. This shows that there were differences in the increase of students' critical thinking ability between the control group and the experiment group.Therefore, it can be concluded that the application of interactive multimedia could improve students' critical thinking ability
Vocational High School Students’ Habits of Mind In Physics Material Through Discovery Learning Models
Get PDFThe Habits of Mind of SMK students must be classified as high, therefore researchers conducted research on investigating the thinking habits of SMK students by using the help of learning models based on problem solving in their own way (Discovery Learning).
