Abstract

Learning media is one of the keys to successful learning in the classroom by improving learning activities to be more effective and efficient. Now the development of learning media is increasingly advanced thanks to advances in information technology. One of the information technology-based learning media that is currently widely used is Virtual Reality. The utilization of Virtual Reality learning media is very appropriate to use in classroom learning that needs to present real examples so that students can understand the material, so as to improve the quality of learning. The purpose of this study is to analyze how to improve the quality of learning based on Virtual Reality technology at Santa Ursula Senior High School Jakarta. The method used is descriptive quantitative research method with data collection techniques in the form of questionnaires, interviews, observations, and documentation studies. The results showed that the use of Virtual Reality can improve the quality of learning in several subjects. The use of Virtual Reality has a positive impact on learning activities, such as learning to be more varied, fun, and interesting. In addition, students' interest in learning in class also increases, because they want to be actively involved in the learning process. However, the use of Virtual Reality at Santa Ursula Senior High School Jakarta is still not optimal. This is because there are still many teachers who are not mature in preparing the use of Virtual Reality media in learning, so the use of Virtual Reality has not been evenly distributed in all classes.

Abstract

Diagnostic tests are strategies used in differentiated learning to adjust the course of learning based on students' existing learning needs. There are several types of diagnostic tests, including the three-tier diagnostic test. Explaining a three-tier diagnostic test instrument that is suitable for use in studying differentiated excretory systems is the aim of this research. The research method is research & development with 4D as a development model. 33 students of class The instrument developed consisted of 20 questions which were then tested for content and empirical validity. Based on the results of validity testing, an average of 92% was obtained, which shows that the instrument is very valid. Empirical validity testing obtained 13 valid questions and 7 invalid questions. In addition, a value of 0.732 was obtained from the reliability testing results, which shows that the instrument developed is reliable. Based on the results of testing the level of difficulty of the questions, it was found that there were 3 easy questions, 10 medium ones, and 7 difficult ones, and from the results of testing the differentiating power of the questions it was found that the questions were not good because they had a negative value of 1, bad had 3, fair and good each had 7, respectively. and very well collected 2. Based on content and empirical validity testing, the results showed that only 13 questions could be used in the differentiated excretion learning system, while the other 7 questions could not be used.
