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

This research problem focuses on the low learning outcomes of students in the Human Reproductive System material, which the lack of variation in learning strategies and low student independence in learning can cause. This study aims to explore the effect of Blended Problem-Based Learning (PBL) assisted by educator blogs on biology learning outcomes on the topic of the Human Reproductive System and student learning independence. With a 2x2 quasi-experimental research design involving 144 grade XI students, the method of determining the control and experimental classes is by randomly drawing 2 classes by taking a roll of the control and experimental classes. The first is the control class, namely learning with the Expository Method, and the second is the experimental class, namely learning with Blended Problem-based learning Assisted by Educator Blogs. The determination of the sample in this study was carried out using a non-probability sampling technique. The technique used in this sample is saturated sampling. Data were collected through pre-and post-tests and analyzed using Two-Way ANOVA in SPSS 27. The results showed that Blended PBL significantly improved biology learning outcomes, especially in students with high learning independence. This study introduces a practical digital approach combining PBL with educators' online resources, providing insights into technology-based learning strategies that can improve students' academic outcomes according to their level of independence.
