Ista Maharsi

Technology advances have profoundly impacted the practice of language classrooms and remarkably encourage teachers to incorporate classroom instructions that accommodate technology, pedagogy, and content. Consequently, teachers from varied education levels have tried adjusting and incorporating technology. The aim of this research is double-fold. First, it aims to investigate how secondary in-service preparation using TPACK in students' Digital Storytelling (DST) projects. Second, it explores how they perceive TPACK as implemented in Digital Storytelling projects. Two in-service teachers participated in this study. Data were collected from teachers' self-assessment reports with 75-item TPACK questions, classroom observations, interviews, and teaching artifacts. The survey data were analyzed descriptively, while the interview and observation data and teaching artifacts were analyzed using Braun and Clark's thematic analysis (2006). This study has three findings. First, teachers believe that enacting the TPACK framework in DST projects is challenging. Teachers must refine their understanding and practice integrating technologies, pedagogies, and content into doable instructions. Secondly, to develop self-efficacy beliefs about technology integration teachers require skills updates through professional development. Thirdly, DST can promote teachers and students to enhance their cognitive and affective engagement and creativity through collaborative projects. Suggestions for future research are provided.

Anxiety is a psychological condition frequently experienced by vocational high school students due to academic pressure, practical training demands, and uncertainty about future careers. This study aims to (1) classify the anxiety levels of vocational students based on their personal narratives shared via WhatsApp conversations and (2) compare the performance of two kernel types in the Multi-class Support Vector Machine (SVM) classification model. A total of 4,257 chat entries were collected from Grade X students in Gianyar, Bali. After preprocessing, 1,476 narrative texts were selected and labeled into five anxiety levels using the DASS-42 scale: Normal, Mild, Moderate, Severe, and Very Severe. The classification model utilized TF-IDF for feature extraction and applied both Radial Basis Function (RBF) and Sigmoid kernels. The evaluation showed that the Sigmoid kernel achieved the highest accuracy (81.42%) and macro-average F1-score (0.7914), demonstrating superior performance, especially in recognizing minority classes. Furthermore, the model successfully identified 11.6% of students with Severe anxiety and 9.1% with Very Severe anxiety, suggesting its potential use in early psychological screening. These findings indicate that Multi-class SVM is effective for anxiety classification based on life story narratives and offers practical value in school-based mental health monitoring.

A Data Science Approach to Classifying Educational Feasibility Across Indonesia: Unsupervised Learning on 2023–2024 Primary School Data

I Gede Aris Gunadi Gunadi

This research is intended to map the conditions and quality of education in provinces in Indonesia. This mapping process is carried out by analyzing the clustering method. Based on elementary school education published by the Indonesian Ministry of Education (Kemendibudristek) 2023-2024. Based on these data, clusters are carried out using the K-means clustering algorithm. The best clustering process was obtained for the number of clusters 3, with a DBI value of 1.02. Further analysis was also carried out based on graphical visual analysis to profile each cluster. To compare the results of the cluster analysis, the education eligibility index of each province was also calculated. The ranking of provinces is carried out based on the value of the education eligibility index. Based on the cluster results, 3 clusters with different characteristics were obtained. Cluster (0) is a cluster with provincial members with secondary education quality. This cluster has the most members, 18 provinces, and the distribution is very heterogeneous. In this cluster, there are provinces whose education quality approaches the good education cluster (cluster (2)), but there are also those that resemble the low education cluster (cluster (1)). Cluster (1) has provincial members that are associated with low education quality. This cluster has 4 provincial members. Finally, Cluster (2) consists of provinces that have good or superior education quality, totaling 17 provinces. This cluster's distribution level is not as heterogeneous as cluster 1. Differences in profiles and characteristics were found in each cluster. This shows that the government should not provide uniform treatment for all regions. Based on cluster analysis in the short term, it is not possible to standardize the same education for all regions.
