Abstract

This study aims to develop an objective test of conceptual knowledge of physics on Mechanical Waves material in high school that meets good test qualification standards, covering aspects of validity, reliability, level of difficulty, discriminating power and effectiveness of distractors. This type of research is research development or Research and Development (R&D), with the ADDIE model. The population of this study were all students of SMA Negeri 2 Percut Sei Tuan with the subject of all students of class XI MIA SMA Negeri 2 Percut Sei Tuan. The instrument used in this study was a multiple-choice test of 50 items to measure conceptual knowledge. The results showed that the content validity by experts of the objective test of conceptual knowledge of physics on Mechanical Waves material in high school was very good. Judging from the empirical validity of the broad field test, 37 valid items and 13 invalid items were obtained. The reliability of the test is 0.91. The level of difficulty obtained 7 easy questions, 27 moderate questions, and 4 difficult questions. The discriminatory power obtained 30 items very good, 5 items good, 2 items enough, and 1 item not good. Based on the effectiveness of the distractors, 20 distractors were found to be inefficient or the distractors were not functioning. This conceptual knowledge test can be used as a standard test to measure students' conceptual knowledge on the Mechanical Wave material in high school.

Abstract

This study was conducted to determine the effect of the Inquiry Training Model on students' critical thinking skills. This research design uses two group pretest-posttest technique. All of Student Class X in SMA Negeri 1 Stabat was the population of this research. Then two classes were selected as samples of the study, one class as an experimental class is taught using the Inquiry Training learning model while the other class as a control is taught using a conventional learning model. The research data collection instrument was in the form of 5 validated essay tests which would later be analyzed using the t test. The results of the study indicate that the inquiry training learning model has a significant impact on increasing students' critical thinking skills compared to students learning with conventional models on momentum and impulse material.Keywords: Inquiry Training, Critical Thinking Skill, Momentum and Impulse

This study aims to determine the level of students' critical thinking skills in distance learning physics subjects using aspects of critical thinking skills according to Ennis. The method used is descriptive with a quantitative approach. The population in this study was all SMA/MA Tanjungbalai City. The research sample was taken by purposive sampling as many as 150 students of class X from 5 sample schools SMA/MA Tanjungbalai City. The research instrument is a test of critical thinking skills and a questionnaire. The critical thinking ability of SMA/MA students in Tanjungbalai City in the subject of straight-motion physics in distance learning is still low overall. The average test of students' critical thinking skills is 55,73 in the low category. With the average achievement of each aspect, namely 61,83 in the aspect of Elementary Clarification, 56,37 in the aspect of Basic Support, 53,60 in the aspect of Interference, 56,17 in the aspect of Advance Clarification, 50,67 in the aspect of Strategy and Tactics. Student responses to distance learning show that all respondents of SMA/MA Tanjungbalai On the aspect of access to the use of distance learning, students gave an average response of 70%, indicating that students still find it difficult to use the distance learning method applied. Understanding the material shows that learning occurs when 78% of students better understand the material in face-to-face learning, and 52% of students understand physical lessons through distance learning. The aspect of implementing distance learning shows that students' responses to the effectiveness of distance learning are weak, with an average response of 65%

Abstract

This study aims to look at the science process skills of students using guided inquiry learning models assisted by the PhET media on the science process skills (SPS) of light subject matter, students in class XI, second semester, of SMA Negeri 9 Medan Academic Years 2018/2019. The population is all students of class XI semester II. With the cluster random sampling technique, the class XI IPA 1 was selected as the experimental class and XI IPA 2 as the control class. Before the study was conducted, the average pretest value of the experimental class was 38.43 and the control class was 38.31. In testing the normality and homogeneity of the two classes, it is obtained that the data of both classes are normally distributed and homogeneous. Furthermore, in the experimental class guided inquiry learning was carried out using PhET media and conventional learning was carried out in other classes. After learning is given then in the two classes conducted posttest with the average results of the experimental class 83.33 and the control class 70.60. From the results of hypothesis testing, there was an increase in students' SPS due to the influence of the PhET guided inquiry learning model on student’s SPS the of light wave principal.Keywords: Learning Models, guided Inquiry, PhET media, Science Process Skills (SPS)

Abstract

This study aims to determine the relationship between effective communication and student learning outcomes in Physics class XI MIA SMA Al Fityan Medan T.A 2020/2021. The research method used is descriptive quantitative with the type of research used is correlational research. To obtain the necessary data, in this study the researchers used a data collection tool in the form of a questionnaire. For effective communication variables, an average score of 74 is in the medium category, while student learning outcomes in Physics class XI MIA SMA Al Fityan Medan get an average score of 87 and are in the medium category. In this study, the correlation coefficient between effective communication and student learning outcomes in Physics class XI MIA SMA Al Fityan Medan was obtained rcount = 0.515 with rtable = 0.162 at the significance level = 0.05, thus rcount > rtable or rcount value is more greater than rtable, then effective communication has a positive relationship with student learning outcomes in Physics subjects. The coefficient of determination (KD) of effective communication is 26.6%. Based on the data analysis and discussion conducted, it can be concluded that the hypothesis which states "there is a positive and significant relationship between effective communication and student learning outcomes in Physics class XI MIA SMA Al Fityan Medan T.A 2020/2021" can be accepted.Keywords: Effective Communication, Student Learning Outcomes, SMA Al Fityan Medan
