This study employed knowledge discovery in databases (KDD) to extract and discover knowledge from the Benue State Polytechnic (Benpoly) admission database and used a structural causal model (SCM) ontological framework to represent the admission process in the Nigerian polytechnic education system. The SCM ontology identified important causal relations in features needed to model the admission process and was validated using the conditional independence test (CIT) criteria. The SCM ontology was further employed to identify and constrain input features causing bias in the local interpretable model-agnostic explanations (LIME) framework applied to machine learning (ML) black-box predictions. The ablation process produced more stable LIME explanations devoid of fairness bias compared to LIME without ablation, with higher prediction accuracy (91% vs. 89%) and F1 scores (95% vs. 94%). The study also compared the performance of different ML models, including Gaussian Naïve Bayes, Decision Trees, and Logistic Regression, before and after ablation. The limitation is that the SCM ontology is qualitative and context-specific, so the fair-LIME framework can only be extrapolated to similar contexts. Future work could compare other explanation frameworks like Shapley on the same dataset. Overall, this study demonstrates a novel approach to enforcing fairness in ML explanations by integrating qualitative SCM ontologies with quantitative ML/LIME methods.

Listening skills are very influential on learning success. Successful learning can run well if students are able to capture messages or information related to the teaching material presented by educators or from reading material. Listening as a learning process is carried out in an integrated manner and receives the same attention as other language skills. However, in reality, most of the listening lessons delivered by educators in elementary schools in particular are still often ignored. In the learning process, educators use learning media, namely less innovative learning media in the form of pictures contained in theme books. Educators still use theme books and worksheets as learning resources and media without any other learning media that can attract students' attention. However, the use of this learning media does not attract students' attention and interest in learning because learning seems boring for students. As a result, many students lack concentration in learning and students are less active in the learning process. Therefore, the author uses the Discovery learning method, which is expected to foster concentration and attract students' attention so that students' listening skills can improve as expected.

This study uses the Classroom Action Research approach which is carried out in two cycles. Each cycle consists of stages of planning, implementation, observation, and reflection to evaluate and improve the learning process. The results of the study showed that the application of the discovery learning model assisted by animated videos succeeded in improving student learning outcomes. In the first cycle, only 23.33% of students achieved complete learning, but in the second cycle, the percentage of students who completed increased to 86.66%. This increase occurs because students are starting to be more active in group discussions and more confident in expressing opinions. The use of animated videos also helps students understand the material in a more visual and fun way. This research makes an important contribution to the development of technology-based learning methods, especially in biology learning. These findings suggest that animated videos in learning can improve student engagement and their learning outcomes. This study suggests that further research be conducted to explore the application of this model to other subjects or at higher levels of education, in order to identify its broader benefits in educational contexts.
