Abstract
Calculus plays a significant role in succeeding in various fields. In line with this, the researchers should identify the relationship between a factor that drives success in the mentioned subject, self-belief, and Calculus performance. This study aimed to determine the level of sources of self-efficacy presented by Albert Bandura, specifically mastery experience, vicarious experience, social persuasion, and physiological state, in the context of students' calculus performance. The relationship between the four sources and the academic performance of the learners in the mentioned subject was also determined. The study was conducted from October 2023 to February 2024 at Cavite State University–Carmona. The participants were one hundred twenty-seven students from the programs BS Computer Engineering, BS Computer Science, and BSE-Mathematics who qualified for the limitations of this study. Descriptive and correlational research designs were utilized to attain the study's objectives. In addition, the researchers adapted and modified a mathematics self-efficacy questionnaire. Both Spearman's rho and Pearson's r were used to determine if there was a correlation between mastery experience, vicarious experience, social persuasion, and physiological state, and Calculus performance. The results showed that students have low confidence or belief in their ability to perform well in Calculus when mastery experiences, vicarious experiences, social or verbal persuasions, and physiological or emotional states are taken into consideration. In addition, it was found that there is a significant negative relationship between the first three mentioned sources of self-efficacy and Calculus performance. On the other hand, the physiological state has a significant positive relationship.
