Abstract

Physics is a subject that consists of concepts related to real life. Empirical phenomena can be observed directly through experimental activities. However, this experimental method is still not optimally applied by teachers in learning. Problems that can be an obstacle in carrying out experiments in schools include difficulties in collecting and analyzing data on some Physics materials, not all schools have adequate practicum tools, and it is difficult to carry out experimental activities in online learning conditions. Based on this, a mixed-methods research was carried out to find a solution to this problem. Qualitative research consisting of literature review about real experimental methods, virtual experimental methods, and the use of video analysis software in physics learning was conducted to obtained innovation on experimental methods. Furthermore, quantitative research was conducted to determine the difference of student’s conceptual understanding before and after being given the intervention. Based on the results of the literature review, it is concluded that the experimental method innovation that can be carried out is the mixed experimental method by combining real and virtual experimental activities. One example of technology that can be used in this method is video analysis software. The results of data analysis showed that there was a difference in concept understanding between before and after given the mixed experimental method. Therefore, the innovation of the learning method can improve students' understanding of concepts in learning Physics.

Abstract

Penanggulangan pemanasan global merupakan salah satu tantangan yang sedang dihadapi dunia saat ini. Beberapa bencana yang disebabkan oleh pemanasan global diantaranya adalah badai, angin ribut, hujan deras, serta perubahan musim tanam. Salah satu upaya yang dapat dilakukan untuk mengatasi permasalahan ini yaitu dengan melakukan strategi geoengineering. Geoengineering adalah suatu upaya untuk memanipulasi iklim bumi guna melawan efek pemanasan global. Akan tetapi, dalam melakukan manipulasi perlu ditinjau etika, kebaikan, keburukan, hingga estetikanya. Artikel ini menyajikan tentang pandangan aksiologi terhadap geoengineering sebagai usaha mengatasi pemanasan global. Kajian dilakukan menggunakan pendekatan kualitatif melalui studi literatur seperti penelaahan terhadap buku-buku, literaturliteratur, dan artikel ilmiah terkait. Beberapa Lembaga terkemuka di dunia telah dan akan meneliti geoengineering dan mencari manfaat potensial dari ilmu ini. Namun, jika konsep manipulasi iklim ini disalahgunakan seperti dijadikan senjata perang dan teknologi untuk menghancurkan suatu wilayah, maka geoengineering dikatakan sudah melanggar etika sains. Oleh karena itu, kajian aksiologi terhadap strategi geoengineering menjadi penting untuk dilakukan.

Abstract

Physics education graduates will produce quality teacher candidates. However, physics education students have difficulty understanding basic electronics lectures. Multiple representation-based lectures are needed to improve students' cognitive understanding and skills. This representative multiple is adapted to student learning styles. The problem comes from the lack of references that explain the learning styles of prospective physics teacher students with multiple representative integrated basic electronics lectures. The problem formulation that arises is how students' learning styles are presented and how basic electronics lectures are represented. The method used is mixed methods with a data triangulation design. Quantitative data comes from questionnaires of 50 students and qualitative data comes from interviews with lecturers teaching basic electronics courses. This research was conducted at a university in West Sumatra. The research results show that student understanding is still low and research needs to be carried out regarding the development of basic electronics programs based on multiple representations to improve students' cognitive understanding

Abstract

Mental models and problem solving skills need to be developed in learning. However, previous study show that students’ mental model and problem-solving skills are not optimal. The solution is to develop an Argumentation Based on Three Levels of Representation (AB3LR) model. This research aims to determine the components, validity, and practicality of the AB3LR model. The method of this study is Design and Development Research (DDR). The instruments used consisted of validation sheets and student response questionnaires. The model was validated by five experts and applied to 19 students taking Statistical Physics courses. The data obtained was analyzed using the Content Validity Ratio (CVR) and Percentage Calculation Method (PCM). The AB3LR model consists of seven stages, namely identifying problems or phenomena, collecting data or information, assimilation and accommodation, presenting tentative arguments, implementing solutions, analyzing and synthesizing the results of discussions, and evaluation. The validation result is 0.99 with a valid category. The AB3LR model is also practical to use with the average percentage is 86.12%. 78.90% and 63.2% students strongly agree that AB3LR model can promote mental models and problem-solving skills. The conclusion of the study is the AB3LR model is valid and practical for use in learning.
