"Fundamentals of Physics" by Halliday, Resnick, and Walker is in its 10th edition (published 2013). This edition describes the basic physics of the same topics as HRK. However, it goes into less detail, omits some of the interesting calculations, and has fewer challenging problems. Although this is a good book, it is not written to train students to the same level of problem-solving ability as HRK. So HRK is recommended for those interested in improving their problem-solving ability to the level of the USAPhO or similar olympiad physics competitions.

Experimenting is a basic skill that science students must have. Experimental activities are generally carried out in the laboratory. But by using a smartphone, many experiments can be done outside the laboratory. This research is an example of an experiment using a smartphone that can be carried out outside the laboratory. This study aims to measure the coefficient of marbles restitution through a simple experiment assisted by a smartphone. Marbles are dropped from a certain height, the Phyphox application on a smartphone will record experimental data through a sound sensor. Experimental data recorded through a smartphone is used to analyze the coefficient of restitution and mechanical energy of marble during a collision with the floor. The experimental results show that smartphones can be used to determine the coefficient of restitution and mechanical energy as an experimental tool. We hope that this experiment will be an alternative method for lecturers or physics teachers to demonstrate bouncing objects to determine the coefficient of restitution and mechanical energy loss.
The aims of this study were to produce learning media based on Yu Gi Oh Physics Smart Card (YOPSA) in order to increase students' interest learning in static fluid material of grade X Vocational High School of 1 Semarang as well as to find out the enhancement of the interest in learning physics of the students who take the part in YOPSA learning media. This study was a Research and Development (R&D) with a 4-D model (define, design, develop, and disseminate). The results of this research showed that the developed product of Yu Gi Oh Physics-based Smart Card (YOPSA) learning media was suitable to according to the assessment by the expert lecturers and physics, and the average results from students score is 3.77 (very good). Otherwise, the Yu Gi Oh Physics Smart Card (YOPSA) learning media was able to increase students' interest in learning physics with gain value 0.40 (medium).
Hypercontent module as one of Technological Pedagogical Content Knowledge (TPACK) learning device contains collaboration between technology, pedagogy, and material content equipped with Quick Response Code (QR Code) as a learning navigation tool that is open source for learning, so it is expected to improve students' creative thinking skills in information processing as new knowledge through technological literacy. This study aims to analyze the effectiveness of the hypercontent module to improve creative thinking skills of prospective physics teachers. The hypercontent module contains various learning resources such as presentation, text, video, images, and exersice that can be accessed via QR Code reader. This research is a pre-experimental research with one group pretest postest design. The research subject is 16 students in Department of Physics Education Muhammadiyah University of Makassar. The data were collected through tests of creative thinking skills with indicators of thinking fluency, flexibility, elaboration, and originality. The results of data collection were analysed with descriptive analysis and N-gain test. This research shows that the hypercontent module is effective to improve the creative thinking skills of prospective physics teachers. This can be seen from the increase in the score of students' creative thinking skills from 64.51 to 72.64 after implementing the hypercontent module.
Energy and environmental conservation problems are increasing every day. The use of electricity began to experience shortages by about 1.6 billion people. The use of fuel oil (BBM) in road transportation requires a larger number along with the number of means of transportation. On the other hand, there is an inefficient use of energy for some equipment used by humans. Gasoline and electric vehicles generally use inefficient internal combustion engines. About 25% of the combustion results are used for vehicle operations, and 40% is lost to waste heat that is wasted. Waste heat is also wasted on household appliances. Global warming and environmental pollution due to the use of inefficient energy are also increasing. Research by experts on thermoelectrics shows good results in overcoming inefficient use of energy and can provide solutions to energy problems and environmental conservation. Its use is flexible, because it does not require complicated mechanical structures, and is also environmentally friendly. This paper provides a review that reviews the use of thermoelectric in various equipment that produces waste heat energy that has not been utilized optimally.
Discrepancy Evaluation Models(DEM) of Information Technology-based Project Assignment Programs in learning Physics are conducted to see whether there are gaps so that the effectiveness of the program can be continued or not. The evaluation technique is carried out by conducting interviews with supporting lecturers, observing lecture processes, and questionnaires to supporting lecturers and students. The results showed that (1) Information technology-based Project assignment program in learning Physics was carried out well with a score of 3.70. (2) The program can be done by giving students assignments by making applied physics products that can be utilized in everyday life, then presented to see the truth of the physical concept and the clarity of the product made, then students upload the video to YouTube to see the market response. (3) Information technology-based project assignment programs in physics learning provide a clear picture of how physics works in the community. The integration of Economics of Science, entrepreneurship, Nature of Science can better provide a clear picture of how Physics works in society. Thus this program can be continued by revising several existing stages.
This research aimed to identify thinking patterns of natural sciences teacher candidate students in understanding physics phenomena. Results of thinking patterns could be used to determine approriate learning models and materials for students' thinking capacity. In this research, thinking patterns were analyzed using Phenomenological Primitive (P-Prims) perspective. A random sampling technique with purposive sampling was used. The sample consisted of undergraduate students majoring in natural sciences education of Tidar University. The research method used in this research was qualitative, accompanied with The Investigation of Lived Experience with Cognitive Psychology type. Data were collected using tests and interviews. The research results show that in explaining unfamiliar physics phenomena which had never been taught before, students used 1) inductive thinking pattern, by calling back their existing, relevant knowledge and 2) deductive thinking pattern, by using synthesized general premises. 2ff7e9595c
