Abstract

Abstract: This study investigates the relationship between students’ collaborative skills and their achievement in chemistry learning, particularly on the topic of acid–base concepts. Collaborative ability plays an essential role in supporting effective learning and knowledge construction, especially in cooperative classroom settings. The research involved 255 eleventh-grade students who completed both a collaborative skills questionnaire and a chemistry achievement test. The collaborative skills instrument consisted of 23 items covering 11 dimensions, while the achievement test assessed students’ understanding of acid–base concepts. Data were analyzed using Spearman’s correlation after confirming normality and identifying a non-linear relationship. The results revealed a positive and significant correlation between collaborative skills and learning achievement (r = 0.501; p < 0.001), with a determination coefficient of 25.1%. These findings indicate that students with stronger collaborative skills tend to achieve higher levels of conceptual mastery in chemistry. Overall, the study emphasizes the importance of developing collaboration competencies to enhance academic performance in science learning.

Abstract

Problem-solving in chemistry is a multifaceted process influenced by both cognitive and social factors, including students’ interpersonal communication skills. This study aimed to examine the relationship between students’ interpersonal communication skills and their problem-solving ability in chemistry learning. A quantitative correlational design was employed, involving 157 eleventh-grade students from SMA Labschool Jakarta, Cibubur, and Cirendeu. Students’ problem-solving ability was measured using a multiple-choice multiple-answer (MCMA) test, while their interpersonal communication skills were assessed using the Interpersonal Communication Competence Scale (ICCS). The results showed a significant but weak positive correlation (r = 0.294) between the two variables, indicating that students with stronger interpersonal communication skills tend to perform better in solving chemistry problems. Although the contribution of interpersonal communication was relatively small, it suggests that social interaction and communicative engagement play a meaningful role in supporting cognitive performance. These findings underscore the importance of fostering interpersonal communication within chemistry education to enhance students’ problem-solving outcomes.

Abstract

The attrition rate of students in higher education is a worldwide issue that profoundly affects both individuals and institutions. Students who fail to complete their studies often encounter economic and social difficulties, while educational institutions suffer a deterioration in reputation and operational efficacy. This paper proposes the creation of a prediction model utilizing the XGBoost algorithm to assess students' academic progress and dropout risk. The model incorporates several elements, such as academic, demographic, and socio-economic, to yield comprehensive insights into students' educational trends. This research utilizes the Predict Students' Dropout and Academic Success dataset, comprising 4,424 data points and 36 attributes. The data underwent normalization via StandardScaler and was divided into five scenarios for training and testing, ranging from a 50:50 to a 90:10 split. The evaluation of the model was conducted utilizing accuracy, precision, recall, and F1-Score criteria. The findings indicate that the model attains peak performance in the 80:20 scenario, exhibiting 88% precision and an 81% F1-Score, signifying an ideal equilibrium between predictive accuracy and risk identification capability. This study demonstrates that XGBoost can serve as a dependable predictive instrument to aid decision-making in the education sector. These findings establish a foundation for formulating targeted interventions aimed at enhancing student retention. Subsequent study may investigate the use of real-time data and sophisticated models to enhance predictive accuracy.
