The present study investigated the interplay of cognitive cues and social cues in instructional videos on students’ knowledge acquisition and sense of social presence. 312 preservice teachers took part in the study. Out of these, 238 participants were randomly assigned to one of three experimental groups receiving an asynchronous online video lecture on three research methods topics, featuring either static slides with voiceover (minimal signaling), dynamic slides with voiceover (moderate signaling), or dynamic slides with additional instructor signaling (maximum signaling). 74 participants served as a control group and completed pre- and posttests without attending the course. Perceived difficulty, invested effort, motivation, and notetaking were included as covariates. Dynamic slides did not improve knowledge acquisition compared to static slides. However, instructor signaling enhanced knowledge acquisition when perceived difficulty was high. Furthermore, instructor signaling significantly increased perceptions of social presence for two of the three investigated topics, highlighting the importance of social cues.

Spirituality and art have been recognized by educators as crucial factors affecting students’ learning outcomes. By taking these two factors into account, this study proposed the project-based STREAM (Science, Technology, Religion, Engineering, Art, and Mathematics) approach to improving students’ learning achievement, 21st-century competencies, computational thinking, and project outcomes in a science course in response to several challenges encountered by conventional STEM education in addressing global issues. A quasi-experimental design was employed, involving 79 participants distributed across three groups: a project-based STEM approach, a project-based STEAM approach, and a project-based STREAM approach. The experimental results showed that students who learned with the STREAM and STEAM approaches performed significantly better on learning achievement, complex problem-solving, creativity, and project quality than those who learned with the STEM approach. Students who learned with the STREAM approach had higher meta-cognition and communication than those who learned with the STEAM and STEM approaches. However, there was no significant difference between students who learned with the STREAM, STEAM, and STEM approaches in the collaboration aspect. Students who learned with the STREAM and STEM approaches had significantly better computational thinking than those who learned with the STEAM approach. Additionally, the integration of the religious aspect cultivated a heightened sense of care for their peers and the environment, as well as respect for differing opinions. The findings could be a valuable reference and provide recommendations for teachers, instructors, and researchers to develop the STREAM curriculum.

With the advancement of technology and the internet, individuals offload their cognitive demands onto the internet to access information and supplement their cognitive capacity. However, heavy reliance on the internet often produces undesirable consequences such as poor metacognitive judgments and memory retention. This study investigated whether these negative effects can be mitigated by making learners more cognitively mindful of their search activities. A total of 104 undergraduate students were randomly assigned to two conditions. In the thinking-before-googling condition, participants had to first generate or guess answers to three brainstorming questions about modern pentathlon, a topic unfamiliar to most college students, before searching to find answers to 15 more specific problems on it. In the googling-only condition, participants were instead shown a keyword slide and immediately started searching the internet for the same 15 problems. The thinking-before-googling group demonstrated significantly higher pre-search curiosity and recall performance compared to the googling-only group. However, no significant group differences emerged in cognitive self-esteem and the estimation of performance and study time. Both groups expressed significantly higher interest in the topic after the search compared to before. Curiosity is discussed as the potential psychological mechanism underlying the benefits of the thinking-before-googling group.

Artificial intelligence (AI) has ushered in an era where Computational Thinking (CT) emerges as a crucial skill. This interconnected, data-driven landscape necessitates deeper CT skills, enabling students to effectively navigate both the opportunities and challenges presented by AI. The flipped classroom model has gained widespread acceptance in CT education owing to its adaptability, interactivity, and personalization. However conventional implementations of the flipped classroom model still face significant limitations such as insufficient student autonomy in learning processes and a need for enhanced quality of classroom interactions. Addressing these, our study introduces a synergy of flipped classrooms with AI, termed the Flipped Classroom with AI Learning Companion teaching model (FC-AIC). This model aims to enhance high school students CT, self-efficacy, and motivational levels compared to traditional flipped classrooms (FC). Our quasi-experimental research involved 60 first-year high school students from central China, divided into control (FC) and experimental (FCAIC) groups over eight weeks. Students completed a questionnaire to self-appraise their CT, self-efficacy, and motivation at pre-intervention and post-intervention stages. Results indicate that FC-AIC significantly boosts student self-perceptions of their own CT skills, specifically in problem-solving and creativity, and improves perceived self-efficacy and intrinsic motivation without notably impacting perceived extrinsic motivation. This investigation highlights how integrating flipped classrooms with AI technologies can synergistically enhance educational paradigms offering new insights about practical innovations for intelligent educational frameworks.
