A Machine Learning Ensemble Approach for Predicting Factors Affecting STEM Students’ Future Intention to Enroll in Chemistry-Related Courses

Abstract

The need for chemistry-related professionals has been evident with the rise of global issues such as the pandemic and global warming. Studies have indicated how an increase in the amount of professionals should start within the classroom setting, enhancing the interest and motivation of students to pursue higher education in the related field. This study aimed to evaluate and predict factors affecting STEM students’ future intention to enroll in chemistry-related courses. Through the use of machine learning algorithms such as a random forest classifier and an artificial neural network, a total of 40,782 datasets were analyzed. Results showed that attitude toward chemistry and perceived behavioral control represent the most influential factors, followed by autonomy and affective behavior. This demonstrated that students’ interest, application in real life, and the development of knowledge and skills are key indicators that would lead to a positive future intention for pursuing the course in higher education. This is the first study that has analyzed students’ future intentions using a machine learning algorithm ensemble. The methodology and results may be applied and extended among other human factor studies worldwide. Lastly, the presented discussion and analysis may be considered by other universities for their education strategies across different countries.

Determination of loyalty among high school students to retain in the same university for higher education: An integration of Self-Determination Theory and Extended Theory of Planned Behavior

“…Upon checking the respondents using SPSS 25, no missing data were seen. In addition, normality test using Shapiro-Wilks presented a quotient within the range of ±1.96 which indicates that the data is normally distributed [51]. In addition, the analysis using Harman's Single Factor Test for Common…”

“…In contrast, the latter category entails substantial correlation among basic learners, mandating their generation to be predicated upon the prior category, which necessitates the continuous generation of the former. A representative method in this vein is the Boosting Cluster Algorithm (BCA) (Islam et al, 2022;Ong, 2022).…”

Determining Ergonomic Appraisal Factors Affecting the Learning Motivation and Academic Performance of Students during Online Classes

“…The learning of students and teaching delivery was changed in the Philippines. Ong [8] indicated the differences in private universities wherein technology was available for most students such as the internet, system and usage, and even the capability of learning. For public schools, modular learning using worksheets was delivered by faculty members from house to house.…”
