Abstract

This research aim to produce a Multimedia Virtual Laboratory on the Reaction Rate Material to train Science Process Skills on the sub-materials of factors that affect reaction rates. The research method used is Research and Development (R&D). The results of the content validation was 91.67%, construct validation was 97.23%, validation related to presentation was 97.23%, validation related to language was 95.84% with very valid criteria. The results of the student response questionnaire stated that the average percentage of responses was 91.25% which could be categorized very practice. The results of the pre-test and post-test scores based on the t-test obtained the value of Sig. (2-tailed) 0.00 < 0.05, as well as the N-Gain analysis score of 0.93 > 0.7 with a high category so that it can be said that the Multimedia Virtual Laboratory developed is effectively used to train students' science process skills.

Abstract

This study aims to find out the impact of Discovery Learning model combined with Student Teams Achievement Division (STAD) method on students' learning motivation in the one of inclusion class at SMAN 10 Surabaya. This study used a Collaborative Classroom Action Research (CCAR) approach with the Kurt Lewin model. This model contain of four stages, among them are: plan, action, observation, and reflection. The subjects on this research were 36 learners, including 4 learners with special needs. The results be seen that in cycle I, the implementation of Discovery Learning had not fully increased students' learning motivation. However, after improvements were made in cycle II by integrating the STAD method, there was a very significant improvement in motivation indicators, especially in the aspect of tenacity in facing difficulties. The mode score of learning motivation increased from 2 to 3 on this indicator, indicating a high learning motivation category. In addition, cognitive learning outcomes also improved, with 69.4% of students achieving learning completeness according to school criteria. Therefore, in summary that the Discovery Learning strategy combined with the Student Teams Achievement Division (STAD) method is effective to improve the motivation and learning outcomes of inclusion class students.
