This study aims to determine the effectiveness of of physics-based learning lesson study with multirepresentation on Basic Physics course I. The subjects of the study are the first level students as much as 42 people divided into 2 classes, namely experimental and control class. The data completion instrument is a skill test consisting of 5 items about the essay. Data analysis is descriptive analysis to see the picture of result learn student process skill by using absorption criterion, learning efficiency, and mastery learning at presenter and postest. The data analysis showed that the average absorption rate of the class was 9.28% with the less favorable category in pretest experimental class at posttest 17.78% less good and 9,30% with less good category for control class at pretest and 17,18% With less good category, while the quality of less effective learning with 0% percentage in the experimental class and 0% for the control class in the category of less effective, student's 0% complete student completeness and incomplete start in pretest experimental class and 4.76% unfinished postest, and 0% at pretest with unfinished category, 14.29% also incomplete for postest control class, and 0% completeness of subject matter and unfinished acceptance in experiment class and 0% unfinished in control class Pretest and postest Thus, it can be concluded by using the programming language used for learning English on Basic Physics course I on the mater I collision and momentum.

This research aimed to design wave visualization based VBA on microsoft excel as a valid physics learning media for senior high school students of class XI. This research used Research and Development method with ADDIE type. The steps of the design of learning media of this wave visualization include Analysis, Design, Development, Implementation, and Evaluation. However, in this research the researchers only implement up to the development step, then conducted media validation using assessment instruments. The instrument used is validation sheets of the wave visualization learning media. assessment is done on three aspects, namely design aspect, learning content aspect, and pedagogic aspect assessed by validator. Validator consists of team experts and users. Expert validator is a lecturer of Physics Education University of Riau, while the user is a teachers from senior high school on pekanbaru. The validation score obtained for the design aspect of the experts and users is 3.62. The validation score on aspects of learning content from the experts and users is 3.60 and the validation score obtained on the pedagogic aspect of the experts and users is 3.73. The validation results of wave visualization based VBA on excel is in the category very high for all aspects assessed, thus this media can be valid and feasible to be used as a valid physics learning media of students class XI in senior high school.
