The purpose of this study was to develop and validate an online contextualized test for assessing students' understanding of epistemic knowledge of science. In addition, how students' understanding of epistemic knowledge of science interacts with learner factors, including time spent on science learning, interest, self-efficacy, and gender, was also explored. The participants were 489 senior high school students (244 males and 245 females) from eight different schools in Taiwan. Based on the result of an extensive literature review, we first identified six factors of epistemic knowledge of science, such as status of scientific knowledge, the nature of scientific enterprise, measurement in science, and so on. An online test was then created for assessing students' understanding of the epistemic knowledge of science. Also, a learner-factor survey was developed by adopting previous PISA survey items to measure the abovementioned learner factors. The results of this study show that: (1) by factor analysis, the six factors of epistemic knowledge of science could be grouped into two dimensions which reflect the nature of scientific knowledge and knowing in science, respectively; (2) there was a gender difference in the participants' understanding of the epistemic knowledge of science; and (3) students' interest in science learning and the time spent on science learning were positively correlated to their understanding of the epistemic knowledge of science.

This research explores the relationships between self-directed learning readiness and transformative learning theory (TLT) reflected by the Constructivist Internet-based Learning Environment Scale (CILES). A questionnaire survey about adult learner's perceptions of Internet-based learning was administered to adults enrolled in classes in community colleges in Taiwan. A total of 593 valid questionnaires were used for the structural equation modeling analysis. The findings confirmed a second-order hierarchical factor relationship of TLT (technical, dialectical and emancipatory learning interests) from CILES. Moreover, the three domains of learning interests of transformative learning were proved to have a developmental relationship, moderated by the readiness of self-directed learning for adult learners in Internet-based learning.

The present study intends to explore the role of collectivism and group potency at group level in predicting individual Internet self-efficacy (ISE) and individual e-learning outcomes for people aged over 45. Group learning has been widely discussed in the research into online formats. However, less study has been carried out about how collectivism and collective group potency affect individual learning decisions, especially using the technique of Hierarchical Linear Modeling (HLM) for cross-level analysis, which provides the solution of case dependency between group members. This study examines the mediation effects of ISE between peer support and e-learning outcomes. It also explores the contextual effects of group potency, and the moderation effects of collectivism and group potency at an individual level. The results show that ISE fully mediates the relationship between peer support and learners' persistence in e-learning, and partially mediates learners' perceived learning and satisfaction. It is noteworthy that the findings do not support direct group-level contextual effects of group potency. Instead, the results suggest that group potency moderates ISE-perceived learning and ISE-satisfaction relationships. On the other hand, collectivism also moderates the relationship between peer support and ISE. This study highlights the group-level effects of group potency, and suggests that adult educators design and deliver e-learning courses with an emphasis on facilitating group processes.
