This study aimed to develop Predict-Observe-Explain (POE) strategy with refutation text based on Newton's Law. The research design used was 4D (Define, Design, Develop, and Disseminate). The participants consisted of 31 students (15 male students and 16 female students) with an age range of 15-16 years selected from the tenth grade of a public high school in Sukabumi, Indonesia. The instruments used were lesson plan validation sheets and a questionnaire containing 20 statements (11 positive and nine negative statements) with a Likert scale. The scores for positive statements move sequentially from four to one, while the scores for negative statements move sequentially from one to four. The analysis used in this study was the Rasch analysis. As a result, the lesson plan's codes for indicators have an unrevised assessment, while the Language, Concept, Strategy, Objective, and Time codes must be revised. The student responses indicated that all students did not agree with all negative statements, except for S26, S07, S28, and S01. Meanwhile, all students agreed to all positive statements given. Thus, it can be concluded that the POE strategy assisted by rebuttal text can better help students to understand Newton's Law material.

This article aims to find out the resources activated by students in solving Newton’s laws in terms of gender. This research is a quantitative descriptive study with two open test instruments. This research was conducted on 10th-grade students at SMK N 1 Muaro Jambi with 11 female students and 11 male students. The facts obtained in this study indicate that students’ thinking about Newton’s law is still lacking during the learning process. Based on the analysis results of the level of understanding of student concepts, female students understand better than male students. Overall, students fail to summon relevant knowledge when facing problems in the form of phenomena. In addition, they failed to use the knowledge they gained to answer questions. Students’ abilities are activated when they understand a phenomenon influenced by students’ original ideas from their personal experiences.

Creativity is important in facing a challenging future life. Therefore, current learning is focused on not only values but also soft skills such as student creativity. Few teachers provide opportunities for students to develop their creativity in the classroom. This creativity can be developed and trained through various learning strategies. Probem-based learning was chosen in this study as a means to increase students' creativity through two learning methods, experiment and demonstration.  This study seeks to determine the effect of experimental and demonstration methods with problem-based learning model on student creativity on Newton's law material.  The subjects included 72 tenth-grade science students in Surakarta, Central Java.  They were selected using the purposed random sampling technique where out of 8 tenth-grade science students in SMA Al Islam, Surakarta, 2 classes that met the research category were selected.  This experimental study collected the data using pretest and posttest for cognitive data and questionnaire using a Likert scale for student creativity data. Data were analyzed descriptively through independent sample t-test. The results showed that both methods through problem-based learning model had a significant effect on the level of student creativity. From the characteristics of the methods and the number of students in the high creativity category, experimental method is superior to be applied. It is implied that teachers can use the experimental method with problem-based learning model in Newton's law to develop student creativity soft skills.

Physics learning barriers have been studied quite a lot, one of which is epistemological learning barriers. This study aims to determine the epistemological learning barriers and what the percentage of epistemological learning barriers on Newton’s law material about motion in one of the engineering class at one of the vocational high school in Indonesia. Therefore, the researchers reported the results of research related to epistemological learning barriers. This research was qualitative descriptive research. The subjects of this research were 65 students with an age range of 14-15 years. The data was collected using tests and interviews, then analyzed using data reduction, data presentation, and conclusions. The data validity was determined using technical triangulation. The results of this research indicated that high epistemological barriers were found in two indicators, namely the incorrect calculation and the difficulty to determine the right calculation units on the Newton’s First, Second, and Third Laws with the percentages of 88.75%, 6.87%, and 98.45% respectively. The average percentage epistemological learning barriers on the Newton’s First Law was 61.7% within the moderate category and the average percentages of epistemological learning barriers on Newton’s Second and Third Laws were 70.61% and 76.50% within the high categories. Based on these results, it can be concluded that students had difficulty calculating and determining Newton’s Laws’ unit of calculation. It indicated that the students experience epistemological learning barriers with a high category.

Newton’S Law

Newton's law of cooling is shown to underestimate the heat flux between a spherical body (droplet) and a homogeneous gas after this body is suddenly immersed into the gas. This problem is rectified by replacing the gas thermal conductivity by the effective thermal conductivity. The latter reduces to the gas thermal conductivity in the limit of t→∞, but can be substantially higher in the limit of t→0. In the case of fuel droplet heating in a medium duty truck Diesel engine the gas thermal conductivity may need to be increased by more than 100 percent at the initial stage of calculations to account for transient effects during the process of droplet heating.
