The integration of STEM education has been promoted to improve the quality of education in the 21st century, with its usage leading to emphasis on the factors influencing the intentions of preservice teachers. Therefore, this study aims to determine the factors influencing preservice teachers’ intentions, as well as the effects of gender and age on the implementation of STEM education. The Theory of Planned Behavior (TPB) was adopted to predict the relationship between knowledge, social influence, attitude, perceived usefulness, control, and behavioral intention (BI) of using STEM education among preservice secondary school teachers. A total of 30 item questionnaires on behavioral intentions were distributed to 201 respondents, with data being analyzed using the Structural Equation Model (SEM). The results showed that perceived usefulness had a positive significance, and a relationship with the attitudes of preservice teachers toward STEM education. Habit had a positive significance in influencing teachers’ behavioral intentions and implementation. Subjective norms did not have a significant correlation with BI and implementation. These results are recommended for providing solutions to analytical problems, and to successfully improve future learning through an educational approach.

This study aimed to examine the potential of micro-lectures as effective technology-based learning media in mathematics. It proposed a hypothesis that using micro-lectures affects learning satisfaction and achievement in mathematics. Data were collected using a questionnaire developed from the acceptance model theory (TAM) and the extended Expectation Confirmation Model (ECM). Respondents comprised 233 students from six classes that used micro-lectures to learn mathematics for one semester at a public junior high school. The data were analyzed quantitatively using structural equation modeling assisted by SMART PLS 3.0 software. The results showed that perceived usefulness was the most significant factor in the learning achievement. Student attitude towards micro-lectures was the strongest positive factor in learning satisfaction. Furthermore, the proposed model explained 76.9% and 77.3% of the factors related to learning and satisfaction in using micro-lectures, respectively. It implies that micro-lectures affect learning satisfaction and achievement in mathematics. These results indicate that using micro-lectures in mathematics lessons increases learning satisfaction and achievement. They could assist schools, teachers, and local education ministries in planning, evaluating, and implementing micro-lectures in teaching and learning activities to improve education quality.
