The Development of Thermal Expansion Practicum Sets to Improve Science Process Skills of High-School Students
Get PDFThis study aims to develop thermal length expansion practicum sets that are expected to improve high-school science process skills (SPS) in expansion material on metal rods. This research was conducted at SMAN 2 Bekasi in class XI by comparing the control and the experimental class. This study uses the ADDIE approach to analyze, design, develop, implement, and evaluate the thermal expansion length practicum sets. The feasibility test of this practicum sets was carried out in two ways: conducting experiments and validating tests from experts. The experimental results for the linear expansion coefficient of an iron bar are 3.09%, the brass is 5.81%, and the aluminum is 7.39% from the reference value. All of the experimental data still below the error acceptance level which is below 10%. The validation results give 85.5% from media experts and 86.1% from material experts. The trials on users obtained 93.9% of teachers and 85.4% of students. The N-gain in control and experiment class then compared to see the increase in SPS in each category. There was an increase in the experimental class SPS value 7.3% higher than the control class, where the SPS value in the experimental class increased by 47.8%. Therefore, it can conclude that the thermal expansion practicum sets is feasible to use and can improve the science process skills of high school students
The Character Education Through Analogy Learning Implementation on Vector Concepts
Get PDFThe problem of this study is the acts of the criminal increase in North Sumatra, so it needs the characters' building begin from school. Besides, the teacher of physics should be able to instill character values through analogy learning about the concept of physics. This study aims to determine the results of physical knowledge and student responses after applying analogy learning to instill character values. The subjects of this study were X-IPA 1 students of SMA Negeri 1 Rantau Utara. This research is descriptive qualitative with two stages, namely the preparation stage (referring to the development that uses the 4-D model namely Defines, Design, Develop, and Disseminate) and the implementation stage. While the instruments used in this study are observation sheets on the implementation of RPP, student response questionnaires, and tests of knowledge competency results. The conclusions of this study are there is an increase in the results of students' physics knowledge competencies and a positive response to the implementation of analogy learning in instilling character education through the concepts of physics taught
The Technology Pedagogy Knowledge (TPK) Teacher Using Worksheet 3D Pageflip Professional for Promoting Argumentation Skills High-Schools Students in Physics Learning
Get PDFThe demands of 21st-century skills highlighted the importance of cooperation between teachers and students to achieve the expected skill. The Pedagogical knowledge of teachers in teaching and technology into things that need to be developed. The pedagogic ability of teachers in the use of technology can be a potential to develop students' abilities argument. This study aims to develop students' ability argumentation through pedagogical knowledge of teachers in using technology. The technology used is the result of the development of student worksheets 3D PageFlip Impulse and Momentum topics. The purpose of this study to look at the ability of students through the application of scientific argumentation (Technological Pedagogic Knowledge) TPK teachers in the classroom. This research is descriptive research. The data collection capability student argumentation performed by administering a written test. The subjects were students of class X at SMAN 1 Yogyakarta Prambanan. Rate scientific argumentation ability of students refers to Toulmin Argumentation Pattern (TAP). The results showed that the complexity of argumentation ability of students still at low level. These results suggest that the ability of the student arguments need to be improved
The Development of High Order Thinking Skills (HOTS) Assessment Instrument for Temperature and Heat Learning
Get PDFAbstract
The aim of this research is to develop the High Order Thinking Skills (HOTS) test instrument. The instrument was presented into a valid and reliable questionary to get information of the XI grade student's HOTS on temperature and heat. The research was done at Universitas Negeri Jakarta. The instrument has been trialed to 41 respondences on April 2018 at SMAN 1 Kabupaten Tangerang. The research was adapted from ADDIE approach which consists of Analyze, Design, Develop, Implement and Evaluate. The instrument consisted of 15 essays which the coefficient of reliability was 0.568, the difficulties and discrimination average were 0.817 and 0.363. Therefore the test instrument is proper to measure the student's HOTS.
 
The Development of Experimental Sets for Measuring Linear Thermal Expansion Coefficient of Metal Using Digital Video-Based Single Slit Diffraction Method
Get PDFThe development of an apparatus for the measurement of linear thermal expansion coefficient of metal by a single diffraction method has been developed. The development was made based on several ideas from previous researchers, as well as to overcome several limitations which yields insignificant results. The development includes the redesign of the primary holder module, the temperature measurement module (using a thermocouple sensor connected to the PC), and the measurement approach of the diffraction pattern distance by means of digital video analysis techniques using Tracker software. The development of the modules as well as the measurement approach that has been done yields very good experimental results. The measured linear thermal expansion coefficient of aluminum has a high level of accuracy and precision. The result is (23.100 ± 0.2186)×10-6/°C, and compared from a reference, i.e., 23.000 × 10-6/°C, the relative error of is 0.95% and the relative standard deviation is 0.43%
The Development of Authentic Assessment Instrument to Measure Science Process Skill and Achievement based on Students' Performance
Get PDFThis study aims to develop an authentic assessment instrument based on students' performance. It can build the science process skill and measure the cognitive aspects of student’s achievement. The procedure of research & development method is adapted from Borg and Gall’s model, consisting collecting information, planning, early product development, preliminary field testing, first product revision, field testing, second product revision, and dissemination. The initial field testing was executed to 15 participants, and the field testing to 31 participants in MAN III Yogyakarta use the One – Shot Case Study model. The results of the study as follows: (1) instruments according to the experts' judgment, physics teachers and peers, in general, was valid, (2) instruments at the preliminary field test and main field test was reliable, and (3) instruments could build skills and measure cognitive achievement’s aspect of the scientific process skills of the senior high-school students for heat and temperature topic
The Effectiveness of Applying STEM Approach to Self-Efficacy and Student Learning Outcomes for Teaching Newton's Law
Get PDFThis research aimed to determine the effectiveness of STEM learning approaches to self efficacy and student learning outcomes in Newton Law material. The design of this research is Quasi-Experiment with One Group Pretest-Posttest Design. The data obtained in this study are self efficacy data and student learning outcomes. Self efficacy result data was obtained through self efficacy scale is given before and after learning using STEM approach. While the data of student learning outcomes obtained through the question of the form of plural choices and essays given to students before and after learning using the STEM approach. Based on the research above, the average value of N-gain in self efficacy and students’ learning outcomes before and after being taught through learning using STEM approach. The average gain of n-gain in self efficacy and students' learning outcomes have increased with moderate category The result showed that STEM learning approach was effective to improve self efficacy and student’s learning outcomes
