Instructor-generated videos have become a popular way to engage students with material before a class, yet this is a relatively unexplored area of research. There is support for the use of videos in which instructors tutor students, but few studies have been conducted within the context of a classroom. In this study, conducted in a large-enrollment college physiology course, we used a randomized crossover design to compare the impact of two types of instructor-generated videos that students watched as part of their preclass assignments. We compared videos featuring only an instructor (instructor-only videos) with videos featuring an instructor tutoring a student (instructor–tutee videos). We analyzed student survey responses and weekly physiology quiz scores and found that students preferred, enjoyed, and valued the instructor-only videos significantly more than the instructor–tutee videos. In contrast to prior literature, students with a grade point average (GPA) below the median (3.49) performed significantly better on physiology quizzes after watching instructor-only videos compared with instructor–tutee videos. Students with a GPA at or above the median performed equivalently on physiology quizzes after watching instructor-only or instructor–tutee videos. We present this study as an example of bringing cognitive science studies into the context of a real physiology classroom.

Research has noted the effectiveness of online tools (e.g., discussion boards) for supporting help seeking among class members. However, help seeking is not necessarily warranted via online learning tools because some factors (e.g., low Internet self-efficacy) may influence students' intention to use them. This study aims to identify the determinants of students' use of a webbased help-seeking tool called EchoLu. For this purpose, a structural model was developed based on technology acceptance model and tested using a structural equation modelling approach.According to the data analysis results, general Internet self-efficacy, information-search selfefficacy, web-based learning self-efficacy, and EchoLu-specific self-efficacy play a significant role in students' intentions to use online help-seeking tools. Contrary to the previous research, no statistically significant relationship was found between general Internet self-efficacy and EchoLu-specific self-efficacy, and between web-based learning self-efficacy and perceived usefulness. Implications of the findings for guiding practitioners in supporting effective help-seeking are presented. Limitations of the study and future research prospects are discussed as well.

In laboratory study environments, dialogue-videos, or videos of a tutor and a tutee solving problems together, have been shown to more effectively improve student learning than monologue-videos, or videos of tutors solving problems alone. Yet, few studies have replicated these findings in the context of authentic university classrooms. Here, we investigate the impact of dialogue-videos, and more specifically the effect of errors made by tutees in dialogue-videos, on student learning in the context of an undergraduate biology course. To understand why, we investigated students’ effort spent on watching videos, perceived influence of dialogue-videos, and worksheet completion rates. We found that higher-performing students perceived that they used the dialogue-videos to review content. We also found that higher-performing, but not lower-performing, students learned better from dialogue videos where tutees made errors. We also discuss the complexities of replicating laboratory studies in the classroom and implications of our findings. Implications for practice or policy: Tutee errors can be intentionally included in dialogue-videos to promote student learning. When students lack the necessary prior knowledge, monologue-videos may be more effective in presenting the course content. When using dialogue-videos, instructors can encourage students to collaborate to resolve any confusion in time to maximise the benefit of dialogue-videos in teaching and learning.
