Abstract

Force diagrams or some say free body diagrams (FBDs), as physics representations, are usually employed to teach and learn physics concepts such as force. Physics education studies indicate that the use of FBDs can support or hinder students’ performance in solving physics problems. This study aims to investigate the type of representations drawn by students and the patterns of students’ answers while solving force problems. By involving 230 preservice physics teachers, questions about the application of Newton’s laws were administered to students to elicit the patterns of students’ diagrams and answers. Results were analysed into three categories: complete, incomplete, and inappropriate force diagrams. In addition, some students did not draw diagrams in solving the problems. Based on students’ answers, the percentage of students drawing incomplete diagrams (54% for horizontal problems and 42% for inclined problems) is higher than drawing complete diagrams (18% for horizontal problems and 35% for inclined problems). The percentage of students who drew inappropriate diagrams in solving horizontal and inclined problems is 20% and 10%, respectively. A few students (8% and 13%) did not draw diagrams for both questions. Students who drew complete diagrams tended to obtain the correct final answer. Some students who drew incomplete diagrams were not able to find the correct answers and even finish the problem. However, some students who drew incomplete diagrams could successfully solve the problem. The group of students who drew diagrams in the inappropriate category tended to demonstrate incorrect and unfinished answers. This study suggests that instructors should not only focus on the correctness of the diagrams but also focus on the completeness of diagrams drawn by students while solving the problems.

Abstract

Diagram gaya merupakan salah satu dari representasi visual yang dipelajari oleh siswa jenjang menengah atas maupun perguruan tinggi. Diagram gaya dilibatkan dalam penyelesaian soal sehingga cara menggunakan diagram gaya menjadi sesuatu yang perlu dikuasai oleh siswa. Hal ini menjadi tujuan dalam penelitian ini untuk mengetahui profil kemampuan representasi diagram gaya siswa SMA di kota Pontianak. Penelitian ini dilaksanakan secara survei dan melibatkan 205 siswa dari tiga sekolah negeri yang berbeda di kota Pontianak. Siswa diuji menggunakan tes representasi diagram gaya yang terdiri dari 8 butir soal dimana masing-masing konteks diujikan dua jenis situasi diantaranya situasi diam dan situasi percepatan konstan. Data dianalisis secara kuantitatif deskriptif. Hasil penelitian menunjukkan bahwa skor rata-rata kemampuan representasi diagram gaya siswa sebesar 48.78 untuk kategori menengah (intermediate). Kemudian, skor rata-rata siswa yang berhasil menyelesaikan soal untuk konteks bidang horizontal sebesar 57.32, konteks bidang miring sebesar 69.51, konteks objek menggantung sebesar 36.83, dan konteks sistem Atwood sebesar 31.46. Hal ini mengindikasikan bahwa sebagian siswa mengalami kesulitan dalam memvisualisasikan permasalahan kedalam diagram gaya dan menjadi perhatian bagi pendidik untuk memberikan pembelajaran kepada siswa tentang representasi ini.Kata Kunci: Profil; Representasi Visual; Diagram GayaAnalysis of Force Diagram Representation Ability in High School Students in Pontianak CityABSTRACTForce diagrams are one of the visual representations studied by high school and college students. Force diagrams are involved in solving problems so how to use force diagrams is something that students need to master. This is the aim of this research to determine the profile of style diagram representation abilities of high school students in the city of Pontianak. This research was carried out by survey and involved 205 students from three different state schools in the city of Pontianak. Students were tested using a force diagram representation test which consisted of 8 questions where in each context two types of situations were tested, including a stationary situation and a constant acceleration situation. The data was analyzed quantitatively descriptively. The results showed that the average score of students' style diagram representation ability was 48.78 for the intermediate category. Then, the average score of students who completed the questions for the horizontal plane context was 57.32, the inclined plane context was 69.51, the hanging object context was 36.83, and the Atwood system context was 31.46. This indicates that some students have difficulty visualizing problems in force diagrams and it is a concern for educators to provide lessons to students about this representation.

Abstract

Solving problems on Newton's law material is not enough just to memorize the formula, students must have the ability to use multiple representations because the concept of Newton's law is very complex, students must be able to analyze the forces acting on blocks according to the idea to make it easier to solve problems. This research aims to describe students' abilities and answer patterns in solving Newton's law of force on an inclined plane using multiple representations. This research used qualitative methods involving 34 students in class XI MIPA SMA Negeri 1 Sungai Raya for the 2023/2024 academic year. Data collection was carried out by giving multi-representation tests in the form of description tests and interviews. From the results of multi-representation tests and interviews, it was found that almost all students were able to write style names completely, and a few errors were found in writing style names. In describing force diagrams, it was found that all students could describe normal force and gravity force, but it was found that some students could not describe pushing force, friction force, and rope tension force.  Then, the ability of students to solve mathematical equations, overall very few students can solve mathematical equations completely and precisely.

Abstract

This study aims to analyze the suitability of physics assessments designed by science teachers at the junior high school level by paying attention to good assessment criteria. This type of research is descriptive-qualitative, involving three teachers in junior high school.  The data collection technique is in the form of assessment archive documentation. The assessment analyzed was divided into three documents, namely motion and force, simple aircraft and static electricity. Data analysis techniques are in the form of data reduction, data presentation and conclusion drawn. The design of an assessment needs to pay attention to several aspects in it, namely the suitability of learning objectives to learning outcomes, the suitability of the competencies given, the use of language, the assessment rubric and the answer key in the assessment. Based on the results of the analysis, the assessment designed has included learning objectives, competencies, and achievement indicators. However, some aspects still need improvement, such as the use of operational verbs (KKO) in learning objectives, language consistency, and the completeness of the assessment rubric and answer key. These results show that the assessment has not fully met the optimal criteria to support learning evaluation.

Abstract

The inadequate capacity of students to recognize and resolve difficulties, particularly with intricate concepts, has emerged as a significant concern in physics education. This project aims to develop a two-tier diagnostic assessment that utilizes augmented reality (AR) flashcards to identify students' challenges in problem-solving. This media-assisted assessment aims to visually represent concepts interactively while examining students' comprehension and the origins of their challenges. The study methodology employs the ADDIE development paradigm, encompassing analysis, design, development, implementation, and evaluation. Validation is performed by subject matter and media specialists, subsequently followed by trials with secondary education students. The study equipment comprises validation sheets, answer questionnaires, and diagnostic examinations supplemented by augmented reality flashcards. The study demonstrates that the two-tier diagnostic test augmented with AR flashcards effectively identifies students' challenges, particularly in grasping concepts and problem-solving processes, as indicated by a Cronbach's alpha reliability coefficient of 0.89. This media-assisted assessment enhances student engagement, as evidenced by survey findings indicating that students perceive it as easier to comprehend physics concepts through the instrument. This research is anticipated to motivate educators and institutions to create more creative AR-based learning media for evaluations and interactive learning
