The initial learning experience is a critical opportunity to support conceptual understanding of abstract STEM concepts. Although hands-on activities and physical three-dimensional models are beneficial, they are seldom utilized and are replaced increasingly by digital simulations and laboratory exercises presented on touchscreen tablet computers.…

This study explored the impact of oxidation-reduction reaction problem difficulty on university students' cognitive load using event-related potentials (ERPs). Forty-eight balanced low and high difficulty problems were designed. Fifteen undergraduate students majoring in chemistry (8 females and 7 males) participated in the study. Results…

Flipped teaching (FT) is an instructional approach centered around students, displacing traditional lectures from the classroom to make room for active learning. Retrieval practice can enhance content recall. This study investigated the effectiveness of lecture-style teaching (TT), FT, and a combination of retrieval practice with FT (FTR) in a…

Neuroscience findings offer promising ways to enhance performance in educational settings. Adolescents often experience sleep deprivation, impacting memory processes crucial for learning. The synaptic homeostasis hypothesis (SHY) posits that non-rapid eye movement (NREM) sleep, particularly slow wave activity (0.5-4 Hz), downscales synapses…

Peer-led team learning is a socially mediated pedagogy where trained peer leaders, students who have completed a course, return to lead students in groups within a targeted course. The effect of peer-led team learning to improve student success in chemistry has been extensively documented but it is unclear if it is just as effective at…

Despite the challenges posed by expository instruction materials, including unfamiliar text structure and abstracted and isolated representation of the contents, they constitute a primary means of studying scientific concepts in higher education. Conversely, utilizing narratives to present the to-be-learned content was conjectured to mitigate some…
