Abstract:
Learning management systems (LMS) have become a key component of teaching and learning in schools. However, the evaluation of student acceptance rates on its implementation so far has not been widely reported. Therefore, this study aims to evaluate the acceptance rate of LMS among students in terms of gender and grade level. The level of student acceptance of the LMS in administration through an online survey using Google forms. A total of 141 students who took physics subjects from class XI and XII, one of the vocational high schools were involved. Acceptance of the LMS uses a 21-item LMSAS (Learning Management System Acceptability Scale) developed by Sezer and Yilmaz in 2019. The LMSAS uses a 5-point Likert scale, from 1 (Strongly Disagree) to 5 (Strongly Agree). LMS acceptance components include Performance Expectancy (PE), Effort Expectancy (EE), Facilitating Condition (FC), and Social Influence (SI). Wright map and Logit Value of Person (LVP) were used to assess LMS acceptance among students. The analysis results show that student acceptance of the LMS is distributed chiefly at a good level of acceptance. As many as 84% of students received the LMS. Based on gender, 65% of male students are quite accepting of the LMS. Based on class, class XII students are more dominant (35.5%) receiving LMS. Thus, most students in public vocational high schools welcome the LMS well.

Abstract:
Parabolic motion is the typical phenomenon in classical mechanics. The students are able to understand the concept by reading the data in the parabolic function. However, there is limited material for visual impaired students to study the parabolic motion data. One of the solutions to overcome this problem is the parabolic motion experiment development using sonification method. Research has been carried out to analyze the accuracy of the frequency produced by the speakers in data conversion assisted by Arduino Uno. The research also analyzes the effect of elevation angle variations on the resulting frequency changes. The data collection process is carried out by analyzing the percentage of accuracy using the average technique of the data recorded by the Phyphox application. The data analysis of the Phyphox application is compared with the data obtained from the Tracker application. From the results of data analysis obtained the percentage value of the velocity for the angle 30o, 45o, and 70o were 99.92%, 99.67%, and 98.42%, respectively. Therefore, it can be said that the preliminary sonification study is feasible to be used in physics experiments on parabolic motion learning, especially for visual impaired students. The final plotting result of this research shows that the frequency versus time at each angle produces a graph in the parabolic form. While the effect of angle variations on frequency changes is that the larger the angle, the slower it will reach the peak frequency.
