This research was conducted to determine the feasibility of the instrument diagram representation test and the effectiveness of Multimedia Learning Modules (MLMs) integrated local wisdom in physics learning activities. The study design used a pretest-posttest control group design. The research instrument consisted of tests and non tests. The test instrument was in the form of five items arranged according to the diagram representation indicators, namely drawing diagrams and their components and performing mathematical calculations according to the diagram explanation. Non-test instrument is a questionnaire study of test instruments. The validation of the test instrument was carried out using Aiken's V. Data analysis techniques used the General Linear Model (GLM) with a significance level of 0.05 to test the effectiveness of integrated local wisdom MLMs in improving student diagram representation. The results showed that the overall item items were declared valid with Aiken's V score in the range of 0.88 to 0.92 and the integrated local wisdom MLMs were effectively used in physics learning activities to improve student diagram representation based on Mean Difference (MD) values of -54,449.

A simple diffraction experiment was designed using banana stem as natural grating. Coherent beams of lasers with wavelengths of 632.8 nm and 532 nm that pass through banana stem produce periodic diffraction patterns on a screen. The diffraction experiments were able to measure the distances between the slit of the banana stem, i.e.

This research aims to develop and find out the effectiveness of Multimedia Learning Modules (MLMs) in improving students' (diagram and physical) representations of physics. This research design used is a pretest-posttest control group design. The research subjects are 10th-grade MIPA students in Samarinda City, East Kalimantan and Batang Regency, Central Java. The research instrument consists of ability tests of representations (diagram and physical) of physics. The data analysis technique used is the General Linear Model (GLM) with a significance level of 0.05 and a standard scale. The results of the research are that MLMs that are implemented properly and effectively are used in high school physics learning activities to improve students' physics (diagram and physical) ability based on Mean Difference values.

This paper develops learning tools in the form of lesson implementation plans (RPP), modules, and assessment sheets. RPP has been developed with a model of guided inquiry as a means of learning activities. The modules are developed in the form of Multimedia Learning Modules (MLMs) which can attract the interest and motivation of students. The assessment sheet developed is an assessment of mathematical and verbal abilities. The results of the validation of the products developed show that the criteria are very feasible to be used in learning activities.

This study aims to determine the application of multimedia learning modules assisted by tracker virtual laboratory (virlab) to train the verbal representation of students in class XI. This study uses observation and documentation methods to collect data. Observation instruments in the form of assessment sheets used to assess the level of representation students by using 2 classes where each class is filled by different educators. The first class is class XI IPA 1 (modelling class) and the second class is class XI IPA 2 (implementation class). The ability of verbal representations of students is assessed based on indicators on the assessment sheet. The results of the analysis show that verbal representation skills based on indicators clearly explain the problem, the ability to express opinions in sentence form, and describe definitions and terms of a concept in the implementation class obtain results that are better than the modelling classes. Whereas, the fourth indicator is explaining the results of the graph in the form of verbal representations in the modelling class obtained results that are better than the implementation class. These results indicate that application of multimedia learning modules assisted by tracker virlab application can be used to train verbal representation skills.
