Abstract

Lecturers are still lacking in developing electronic statistics course tests through Virtual Learning Unesa (Vinesa), which causes student learning outcomes to decline. The aim of this study was to test the feasibility and effectiveness of electronic central tendency material tests. Data analysis uses quantitative descriptive and t tests. The research subjects were 1 material expert, 1 media expert, 1 language expert, and 28 students. Data collection uses tests, observations, interviews, and questionnaires. The ADDIE model is used in this development research. The feasibility results of material validation, learning media, language, individual and small group trials are each in the very feasible category; the effectiveness results show that the control class (0.45) is in the low category and the experimental class (0.6) is in the sufficient category; and the test results t on sig. (2 tailed) = 0.000 < 0.05. Conclusion The development of electronic tests with central tendency material is suitable for use in tests and is effective in improving students' reasoning abilities. The implication of this research is the development of electronic test products that can be monitored for their level of feasibility, with the aim of improving student reasoning in statistics courses.

Abstract

There are still many educators who develop tests without going through the stages of item analysis, so the quality of the test items is unknown. This has an impact on the accuracy of the item measurement results. This study aims to analyze the empirical quality of the question items in the final examination of the graphic media development course. The research method used was a descriptive method with a quantitative approach. The data collection technique was the analysis of the answer sheets of student work on the final examinations. The population was made up of students with a total of 90 students. The data were analyzed using the Microsoft Excel 2010 application to determine the level of difficulty, discriminating power, distractor effectiveness, validity, and reliability. The empirical quality research results from a total of 25 multiple-choice items for the item difficulty index. Then, for the effectiveness of the distractor, there were 15 (60%) effective items and 10 (40%) ineffective items. Meanwhile, for the validity of the items, there were 24 (96%) items in the valid category and only 1 (4%) item in the invalid category. The reliability of the test using Cronbach's alpha was in the very high category, namely 0.812. Thus, it can be concluded that the semester final examination for graphic media development courses is appropriate to be used as a tool to measure student competency.

Abstract

The problem in this study is the low utilization of digital literacy and learning independence by students, which has an impact on the learning outcomes of statistics courses that are below standard. This study aims to analyze the influence of digital literacy on statistical learning outcomes, the influence of learning independence on statistics learning outcomes, and the influence of digital literacy and learning independence simultaneously on statistical learning outcomes. This type of research is ex-post facto with research subjects of 90 students in the Department of Educational Technology. The data collection technique used questionnaires to measure the variables of digital literacy and learning independence, while learning outcome data was obtained from statistics course scores. Data analysis was carried out using multiple linear regression with analysis prerequisite tests including normality, linearity, multicollinearity, and heteroscedasticity tests. The results showed that digital literacy had a significant effect on statistical learning outcomes with a significance value of 0.00 < 0.05 and a contribution of 73.5% (R²), learning independence also had a significant effect on statistical learning outcomes with a significance value of 0.00 < 0.05 and a contribution of 48.6% (R²), and simultaneously digital literacy and learning independence had a significant effect on statistical learning outcomes with a significance value of 0.00 < 0.05 and contribution of 75.7% (R²). The conclusion of this study is that digital literacy and learning independence have a significant effect both partially and simultaneously on student learning outcomes. The implications of this study show the importance of strengthening digital literacy and learning independence in an effort to improve students' academic achievement, especially in statistics courses.

Abstract

The study aims to develop and validate open-ended mathematics questions, where measuring students' abilities at the field test stage is part of the final validation process to show that the instrument is functional. The development model with Tessmer's formative evaluation approach includes self-evaluation, expert review, one-to-one, small group, and field tests. The participants included one lecturer, two mathematics teachers, and students from grade IX. Individual trials involved three students, small group trials 12 students, and field trials 40 students. The data obtained came from quantitative and qualitative data. The instruments used included observation sheets, interviews, questionnaires, and tests. Analysis for quantitative data was carried out using the SPSS application. The findings of the study indicate that (1) this study produces a mathematics question product with an open-ended approach of 5 descriptive questions. Content validity (90.33%), construct validity (94.25%), and language validity (92.25%). High validity is caused by the formulation of questions that explicitly ask students to provide various ways, which directly target indicators of fluency and flexibility in creative thinking. In addition, the validity of each question item in the small group, namely r count > r table (0.576), with a reliability value of 0.931. (2) Open-ended math questions that are valid and reliable, so that they are used to measure students' creative skills in problem solving. Based on the results of the field test (20% of students are very creative, 30% creative, 10% quite creative, 5% not creative, and 5% very not creative), this proves that the instrument developed is able to differentiate the level of student ability. This study concludes that the development of math questions with an open-ended approach is feasible to be applied to measure creative thinking skills in solving math problems related to the two-dimensional plane geometry topic.      Keywords: creative skills, feasibility of mathematical problems, open-ended approach, two-dimensional plane geometry topic.
