Educational videos are increasingly used to let students prepare lesson material at home prior to in-class activities in flipped classrooms. The main challenge of this teaching strategy is to stimulate students to watch these videos attentively before going to class. This paper describes the use of questions that pop-up within relatively long…

Studies have shown the potential of explainer videos. An alternative is a written explanation, as found in science textbooks. Prior research suggests that instructional explanations sometimes lead to the belief that a topic has been fully understood, even though that is, not the case. This 'illusion of understanding' may be affected by the medium…

The German National Education Standards (NES) for biology were introduced in 2005. The content part of the NES emphasizes fostering conceptual knowledge. However, there are hardly any indications of what such an instructional implementation could look like. We introduce a theoretical framework of an instructional approach to foster students'…

Metacognitive ability is enormously important for improving students' learning performance. However, overconfidence bias may hinder students' metacognition abilities. Therefore, in this study, we conducted an intervention to reduce or debias overconfidence among students using the KAAR (knowledge, awareness, action, and reflection) model. Ninety…

This study tests the influence of a video-based, analysis-of-practice professional development (PD) program on upper-elementary teachers' science content knowledge, pedagogical content knowledge, and teaching practice and on their students' achievement. Using a cluster-randomized experimental design, the study compares the outcomes for teachers in…

A flipped classroom is one where students are first introduced to content outside of the classroom. This frees up class time for more active learning strategies and has been shown to enhance student learning in high school and college classrooms. However, many studies in General Chemistry, a college gateway science course, were conducted in small…

Lecture capture technology is fairly new and has gained interest among higher institutions, faculty and students alike. Live-lecture (LL) is captured in real-time and this recording, LC, is made available for students to access for later use, whether it be for review purpose or to replace a missed class. Student performance was compared between…

The purpose of this study was to investigate whether the flipped (revised) learning had effect on student learning outcome. Lage et al (2000) describes the flipped classroom as " Inverting the classroom means that events that have traditionally take place inside the classroom now take place outside the class and vice versa" (p.32). The…

"Flipped classroom" teaching methodology is a type of blended learning in which the traditional class setting is inverted. Lecture is shifted outside of class, while the classroom time is employed to solve problems or doing practical works through the discussion/peer collaboration of students and instructors. This relatively new…

We report the student response to a two-year transformation of a one-semester organic chemistry course for nonchemistry majors. The transformed course adopted a peer led team learning approach and incorporated case studies. Student attitudes toward the course transformation were assessed throughout the semester, and adjustments to the methods were…

Organic Chemistry is recognized as a course that presents many difficulties and conceptual challenges for students. To combat the high failure rates and poor student attitudes associated with this challenging course, we implemented a "flipped" model for the first-semester, large-enrollment, Organic Chemistry course. In this flipped…

The study investigated the effects of developed electronic instructional medium (video DVD instructional package) on students' achievement in Biology. It was guided by two research questions and two hypotheses, using a quasi-experimental, pretest-postest control group design. The sample comprised of 180 senior secondary, year two students from six…

We present the effect of video demonstrations on student performance in an online Astronomy course. We find that students who watched the videos performed better on related exam questions compared to those who did not watch the videos. We also find that students in the online course performed as well as students in a nearly identical face-to-face…

This study investigated the use of multimedia materials to enhance student learning in a large, introductory biology course. Two sections of this course were taught by the same instructor in the same semester. In one section, video podcasts or "vodcasts" were created which combined custom animation and video segments with music and…

Two experiments examined the effects of a multimedia technology referred to as "Time Compressed Animated Delivery" (TCAD), on student learning in a junior-level reproductive physiology course. In experiment 1, participating students received one of two presentations of the same instructional material: TCAD and a lecture captured on video. At the…
