The Effectiveness of Web-Based Assessment on Student’s Understanding of Concepts on Equilibrium and Rotation Dynamics
Get PDFThis study aims to determine the effectiveness of using a web-based assessment on students’ conceptual understanding of equilibrium and rotation dynamics. The method of collecting data using a quasi-experimental design with an experimental procedure is One-Group-Pretest-Posttest Design. The data analysis technique used descriptive statistical calculations in pretest, posttest, and N-gain scores. Besides, using different test paired sample t-test, effect size, and g-factor. The results other the pair results ed-sample t test showed-test the use of web-based assessment had a very large effect on students’ mastery of concepts as indicated by the difference in the pretest and posttest scores. With the g-factor, there is the effectiveness of learning using a web-based assessment, and there is an increase in scores due to treatment, and students’ initial ability does not influence it. With a correlation test for pretest and N-gain scores and a correlation test for pretest and posttest scores, web-based assessment effectively facilitates all students

This research is a quasi-experimental type with a pretest-posttest control group design. The research sample was taken using a cluster sampling technique. The sample consisted of the experimental class (PGMI A) composed of 41 students using the Inquiry-Interactive Demonstration model. The control class (PGMI B) was composed of 41 students using conventional learning models lecture and assignment methods. The data collection technique used was a test through quizizz, google form, observation, and documentation. The data analysis technique used descriptive statistics which were, preceded by a normality test. Hypothesis testing using the T-test. The results showed that the pretest-posttest mean score increased, namely the pre-test 68.49 and the post-test 85.27 with Tcount 11.95 > Ttable 2.023. Then the results of the sig value. 0.000 < 0.05 means that using the Inquiry-Interactive Demonstration model has a significant effect on students' critical thinking abilities on the topic of waves and sound
Learning Ohm's Law through Electric Puzzle Media
Get PDFElectrical circuit components or electronic circuits can be connected with series and parallel circuits. The arrangement of the circuit can affect the desired lamp characteristics. This study aims to measure the magnitude of resistance in an electrical circuit, analyze the flame of a series and parallel resistance, explore the relationship between voltage (V) with current (I) in series and parallel circuits. The method research used quantitative methods based on the problem-solving laboratory. The laboratory equipment used consists of a battery, incandescent lamps, resistors, stacking and zinc puzzles, multimeters, jumper cables. The laboratory equipment assembled and measured the intensity of the light produced using the physics toolbox application on a handphone. The data has obtained, then presented in a table and calculated using a formula, and analyzed the uncertainty in its measurement. The result showed the intensity of light in a series of different magnitude, the power of the light was more significant in lamp one, and in lamp two, the power was smaller. The intensity of the light in the parallel circuit was the same magnitude. Still, the value of the light intensity in the parallel circuit was smaller than the intensity in the lamps arranged in series. The relationship between voltage (V) and current (I) in both series and parallel circuits was comparable and directly proportional. Thus, the developed series of electric puzzles can adequately explain Ohm’s law. Ohm’s law learning with electric puzzles can be used in school and learned by students quickly
An Investigation of Physics Teachers’ Multiple Representation Ability on Newton’s Law Concept
Get PDFThe ability of the teacher to represent a concept using various types of representation is a critical competency. Teachers who have limited multiple representation abilities will not be able to provide a holistic and appropriate learning experience because students have different abilities in constructing their knowledge. This study aims to determine the multiple representation ability of Physics teacher by using instruments to test multiple representations on the topic of Newton’s law consisting of text representations, images, pictorial diagrams, tables, graphs, and mathematical equations. The subjects in this study were 30 high school Physics teachers in North Maluku who were determined based on the purposive sampling technique. Data on multiple teacher representation abilities were analyzed using descriptive statistics. The results of the data analysis showed that the multi-representation ability of high school physics teachers in Newton’s law concept was in the medium category (55.7%) with the highest achievement occurring in the type of mathematical representation and the lowest in the pictorial diagram representation types for both female and male teachers. Besides, based on data implemented using SPSS 2.0, it can be concluded that there are no significant differences with the ability of teacher’s multi-representation based on gender and teacher’s teaching experience

The results of the validation test of the National Examination test instrument by material experts showed that the National Examination test instrument that had been developed had very good quality (91.25%) when viewed in terms of material. Besides, the results of the validation test of the National Examination test instrument by media experts showed that the National Examination test instruments that had been developed had very good quality (87.5%) when viewed in terms of media. In the first stage of the empirical test, the first reliability test device was quite good, while the second test device showed sufficient reliability. Besides that, the two test kits showed that all items were declared valid. The results of the Person fit for the test respondent of the first test device, and the second test device showed that there were no respondents who were inconsistent, careless, lucky, or cheating. In the second stage of the empirical test, the first test device showed quite good reliability, while the second test device showed sufficient reliability. Besides that, both the test kits show that all items are declared valid. The results of the Person fit for the test respondent of the first test device, and the second test device showed that there were no respondents who were inconsistent, careless, lucky, or cheating. In the third empirical test, the first test device showed good reliability, while the test device showed sufficient reliability.
