Review and Comparison of Four-Tier Multiple Choice and Five-Tier Multiple Choice Diagnostic Tests to Identify Mastery of Physics Concepts

Misconceptions of a concept in a lesson will have an influence in understanding the next concept. Having misconceptions that exist in learning can understand the nature of the misconceptions and consequently can help student learning progress. Therefore, a diagnostic test for misconceptions is needed, including the newest four-tier multiple choice and five-tier multiple choice. This research is a literature review that provides information systematically using the PRISMA method which often occurs in students' misconceptions in high school physics subjects. The data for this research are 60 selected articles from 2017-2021. The purpose of this study is to reveal the use of four-tier multiple choice and five-tier multiple choice diagnostic tests in physics and also provide a comparison of each instrument with the strengths and weaknesses of the four-tier multiple choice and five-tier multiple choice diagnostic tests. Furthermore, the use of multiple choice four levels (83.33%) and multiple choice five levels (16.67). %). In the use of the four-tier multiple choice physical material diagnostic test, which are often used in identifying misconceptions, are optical devices (12%) and energy businesses (10%). And the use of an additional five-tier multiple choice instrument diagnostic test that is often used is to present an overview or conclusion at the fifth level. However, each type of four-tier multiple choice and five-tier multiple choice tests has its own advantages and disadvantages in assessing students' conceptions

Should we teach free-body diagrams before or after Newton’s Laws?

There are two interesting lesson sequences for teaching force and motion in high-school physics. These are teaching free-body diagrams before Newton’s laws (FbN) and teaching Newton’s laws before free-body diagrams (NbF). Both sequences were found in physics textbooks. Different authors adopted the sequence that they believe it would affect student understanding better. However, some physics experts did not agree with this. It is therefore interesting to know if we should teach with the FbN or NbF sequence. This motivates us to study the effect of such lesson sequences on student understanding of force and motion. The sample group was grade-10 students from two physics courses in 2020. One course was taught with the FbN sequence (29 students) and the other with the NbF sequence (34 students). Their understanding was evaluated by using an assessment test which consisted of three parts including (1) Newtonian concept, (2) problem solving, and (3) free-body diagrams. The result shows that for the Newtonian concept part, the average scores are 11% for the FbN and 13% for the NbF sequence. The average scores of the problem-solving part are 13% and 9% and those of the free-body diagram part are 41% and 48% for the FbN and NbF sequences, respectively. The scores of all parts between the two sequences were not significantly different. In addition, student difficulties found in all parts were similar. However, a larger number of students who could provide the equation of motion (F = ma) in the problem-solving part was found in the FbN sequence. We might conclude that teaching free-body diagrams before or after Newton’s laws did not affect student understanding in the topic of force and motion. Detail of student difficulties in both sequences will be further discussed.

The Improvement of Physics Teachers’ Competence in Developing an Interactive Recitation Programs to Remediate Students’ Misconception

During learning from home, the teacher is very limited in giving feedback on assignments. Consequently, students’ understanding of physics concepts is still low and experiencing misconceptions. Therefore, teachers should able to develop an interactive recitation program completed by corrective feedback that could remediate students’ misconceptions. The research objective is to improve the competence of physics teachers at Sijunjung Regency through mentoring in developing an interactive recitation program. This sort of research is quasi-experimental with one-group pretest-posttest design. The research data was obtained from the pretest and posttest about understanding of the interactive recitation programs. The results showed that there was an increase in the knowledge of high school physics teachers in understanding the interactive recitation program with a percentage of 32.4%, and the provision of mentoring activities have a significant effect on increasing the competence of physics teachers in developing interactive recitation programs.

Emerging Online Science Teaching Practices: Insights from High School Physics Teaching Cases in South Korea during COVID-19 Pandemic

By analyzing cases in South Korea, this study examined high school physics teachers’ online teaching practices during the first semester of school lockdown due to COVID-19. A total of eight physics teachers participated in this study. Data sources included observations of online classes, interviews with the teachers, and lesson materials. Data analysis was informed by social practice theory and literature on online learning. As a result, teachers’ practices were distinguished based on teaching emphases including content explanation, participatory learning, and independent first-hand experience. Through the application of various technological tools, teaching practices varied in terms of the degree of interactions and student self-directedness. Three essential practices of physics teaching, defined as those preserved from on-site teaching, were identified. Those features reflected the nature of schooling and the subject matter. The teachers were found to have professional development opportunities through online teaching experiences. Implications for professional development and further research topics are suggested.

Demonstrating Tangential Velocity by a Self-Coded Robot

Tangential velocity is a concept that is often taught as a part of rotation, and is the linear velocity an object has as it turns about a fixed axis. The main goal of this research project was to examine this concept and demonstrate it on a self-coded robot. The robot was designed with two rotating motors with two wings of different lengths to be attached on top, and the motors were connected to a circuit board and coded using the programming language C to rotate with equal and constant angular velocities upon initiation. The main hypothesis is that the length of rotating wings is directly proportional to the tangential velocity of the wings. The project provides a new way of demonstrating tangential velocity in a high school physics class.

Attitudes towards physics. A study with high school students from the Colombian context

Science education should promote the development of competent students in science and develop their interest in science; however, although the role and relevance of science within society is evident; the interest towards it is not conscious, being the negative attitudes of the students the main problem in the teaching of physics, which translates into a deficient knowledge and lack of scientific vocation. This report aims to diagnose the attitudes of students in high school physics courses. The study was developed through a non-experimental, descriptive research design, obtained from the application of a Likert scale that evaluates attitudes towards physics, adapted and validated to the context of students in an educational institution in Colombia. The results indicate that the attitudes of the students are slightly favorable, which is an empirical precedent to continue with the studies on attitudes towards physic. This should be considered to enhance the learning processes in these students, especially for those who have their first approach to physical concepts and give importance to attitudes when teaching.
