Abstract

This study is a development research, which aims at developing learning tools using Schoology to enhance learning motivation of students on chemical equilibrium subject which is valid, practical and effective to be applied. The development model used in this study referred to Hannafin & Peck’s development model which consisted  of need assessment, design, development and implementation. The learning tools using Schoology which had been developed; then, it was validated by two experts. After the validation, the tryout of the learning tools using Schoology was conducted at SMA Negeri 1 Polewali Mandar in grade XI MIPA 4 with the total of 30 students. The result of the study reveals that the learning tools using Schoology development which had been validated shows the mean score of 3.40 which is in valid criteria. The learning tools using Schoology is stated as practical and effective because the practical test which related to: (1) the implementation of learning tools using Schoology is in M = 1.85 in the category of (1.5 ≤ M ≤ 2.0) meaning that the aspect and criteria observed in the implementation of learning tools using Schoology is in entirely implemented category, (2) teachers gave a very positive response on the learning tools using Schoology by 100%, and (3) the students gave a very positive response on the learning tools using Schoology by 85.49%. The learning tools has met effective criteria with the following result: (1) the enhancement of learning motivation of students is from 72.89% to 84.28%, (2) the learning activity of students with the mean score 91.33 is in very active category, and (3) the learning result of students has met effective criteria (≥80%) with the mean percentage of 85.60% which overall is stated as it has met the minimal completeness criteria of the subject.

Abstract

This study is a quasi-experimental research (quasi-experimental), which is aims to determine the effect of Uno card media in the cooperative learning model type STAD toward the student’s achievement of class XI MIPA SMA Negeri 1 Polewali Mandar. The study design used is " pretest posttest-only control group design". These study population were all the students of class XI MIPA SMA Negeri 1 Polewali Mandar which is consists of five classes. The sampling technique used is simple random sampling so that the sample are a class XI MIPA 5 as an experimental class and class XI MIPA 3 as control class with the number of students each 26 peoples. The independent variable in this study is the Uno card media in cooperative learning model STAD and the dependent variable is the student’s achievement. Achievement’s data were analyzed using descriptive statistics and inferential statistics. The analysis showed the average value of student’s achievement on the experimental class at pretest and posttest respectively, are 45.38 and 92.04 with an average of N-Gain 0.860 and the control classes, namely 25.50 and 82.00 with an average of N-Gain 0.774.The results of the hypothesis testing using the Mann-Whitney test values obtained Zhitung = 2.059 and the significance level of α = 0.05 was obtained Ztabel = 1.64. Therefore, Zhitung>Ztabel, so H1 is accepted and H0 is rejected. It shows that there are effect of Uno card media in the cooperative learning model type STAD toward student’s achievement of class XI MIPA SMA Negeri 1 Polewali Mandar on the subject matter of hydrocarbons.
