How Micro-Lectures Improve Learning Satisfaction and Achievement: A Combination of ECM and Extension of TAM Models

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