This paper presents a new approach for content analysis and semantic summarization of instructional videos of blackboard presentations. We first use low-level image processing techniques to segment frames into board content regions, regions occluded by instructors, and irrelevant areas, then measure the number of chalk pixels in the content areas of each frame. Using the number of chalk pixels ...

Many Australian tertiary institutions provide support for academic staff in the design and development of online teaching and learning resources, often employing a centralised unit staffed with educational and instructional designers, multimedia and online developers, audio/video producers and graphic artists. It is not unusual for these units to have evolved from print-based distance education...

This article identifies resources to be included in a website designed to facilitate the integration of instructional games in K-12 settings. Guidelines and supporting components are based on a survey of K-12 educators who are integrating games, an analysis of existing instructional game websites, and summaries of literature on the use of educational software in K-12 settings and teacher techno...

The tool created here is an instructional video that demonstrates how to create models of the heavy and light chains of an antibody using pipe cleaners, and how the process of V, D, and J gene recombination functions, using the model as a visual aide. The video was created by undergraduate students, with the intended audience being other undergraduates. This type of direct peer teaching aids in...

This paper describes a computer-based training method in which novice learners view video clips of authentic performance situations and annotate the video clips by describing critical incidents that they observe in the video clips and noting the time code where the incident occurs. Experts’ observations about the same video clips are offered to learners as expert-model feedback. Learners work t...

1 corresponding author: Chun-Hong Huang Abstract— In e-learning, video is widely used in many course domains. We address the problem of the lecture recording and the organization of visual information through user’s interaction at different steps. Our work focuses on the following three important areas: (1) synchronization method of the material contents and (2) interactions between material an...

The study is based on the use of a flexible learning framework to help students improve information processes underlying strategy instruction in EFL listening. By exploiting the online videotext self-dictation-generation (video-SDG) learning activity implemented on the YouTube caption manager platform, the learning cycle was emphasized to promote metacognitive listening development. Two theorie...

In this paper, we propose a visual saliency algorithm for automatically finding the topic transition points in an educational video. First, we propose a method for assigning a saliency score to each word extracted from an educational video. We design several mid-level features that are indicative of visual saliency. The optimal feature combination strategy is learnt from a Rank-SVM to obtain an...

The study examines the effectiveness of using computer games for after-school remedial mastery learning. We incorporated instructional materials related to “area of a circle” into the popular Monopoly game to enhance the performance of sixth-grade students learning mathematics. The program requires that students enter the answers to avoid the shortcomings of multiple-choice questions. Throughou...

Introduction Today's distance education systems include resources for individual study (intrapersonal dialogue) such as self-instruction texts, Webbased instructional systems, video recordings, etc., and resources for interpersonal dialogue such as tutorials, telephone counselling, synchronous and asynchronous conferencing, and email. Given this diversity, we analyzed some aspects of Open Unive...
