The influence of Bloom's two-sigma…

Background: With the rapid proliferation of online education, it is incumbent upon teachers to find ways to provide online students with science laboratory experiences. Existing research on online labs focuses heavily on computer-supported inquiry learning environments, such as virtual laboratories and remote laboratories. There are limited…

The main objective of this intervention study was to investigate the effect of three teaching approaches, namely the traditional teaching method (TTM), a teacher-based demonstration experiment (TBDE) and a student hands-on experiment (SHE), on students' academic performance. A total number of 324 senior five students studying chemistry as one of…

Motivation, belonging, and inclusion are all critical factors for student success but can be difficult to support in asynchronous online courses. Active learning and required group work have been shown to increase student motivation in in-person and synchronous online courses, but little is known about their impact in online asynchronous settings.…

This study aimed to examine the effect of four types of assessment on overall student success in an online college-level climate change course. Quizzes, midterms, lab assignments, and a capstone project as well as knowledge check questions were used to assess different aspects of student learning, consistent with Bloom's taxonomy hierarchy.…
