Abstract

This research aims to analyze the implementation of the STAD (Student Teams Achievement Division) learning model in improving student learning outcomes in Catholic Religious Education at St. Yoseph Middle School, Medan. The study was conducted at St. Yoseph Middle School using a qualitative approach. A total of 10 informants, consisting of teachers, students, and educational staff, were selected as primary data sources. Data were collected through direct observation, in-depth interviews with informants, and documentation of learning activities. The findings indicate that the application of the STAD model enhances student motivation, active participation in group discussions, and their understanding of Catholic religious teaching material. Interaction and collaboration within groups encourage students to express their opinions more confidently and assist each other in comprehending the material. However, challenges such as differing levels of understanding among group members can be addressed through teacher guidance. This research demonstrates that the STAD learning model is effective in creating an interactive learning environment and improving students' learning outcomes in Catholic Religious Education.

Abstract

This study aims to analyze the response of the Indonesian capital market to the announcement of Unusual Market Activity (UMA) issued by the Indonesia Stock Exchange (IDX) by examining abnormal return and trading volume activity (TVA) of listed stocks during the 2023–2024 period. The research employs a quantitative approach using an event study methodology, with an observation window of 11 days consisting of five days before the announcement, one day on the announcement date, and five days after the UMA announcement. The research sample was determined using purposive sampling, resulting in 168 UMA announcement events that met the research criteria. Data were analyzed using normality tests, followed by the Wilcoxon Signed Rank Test due to non-normal data distribution. The findings reveal a significant difference in abnormal return before and after the UMA announcement in both 2023 and 2024, indicating that UMA announcements contain information that is responded to by the market through stock price adjustments. However, the analysis of trading volume activity shows no significant difference before and after the UMA announcement in both periods. These results provide empirical evidence that UMA announcements exert an asymmetric impact on market reactions and support the notion that the Indonesian capital market exhibits characteristics consistent with semi-strong form market efficiency
