As the large lecture course continues to be a component of many college programs, the potential of online technology to enhance such courses remains a question for researchers. To what extent can such technology result in saving financial resources and teaching time? How do students attending lectures respond to online course components? Does such technology have a noticeable impact on student performance and remote learning? In a study conducted at the University of California (UC), Berkeley, authors Diane Harley, Jonathan Henke, and Michael W. Maher compared traditional and technology-enhanced versions, including video lectures streamed over the internet, of an undergraduate chemistry course over a two-year span. In their findings, the authors indicate significant potential savings of money and teaching time after the second year as well as positive student attitudes towards the technology. Although the technology-enhanced version of the course did not result in any noticeable differences in student performance, the authors conclude that the benefits of online technology for large lectures remain substantial, particularly in providing stressed students with flexibility in their use of time and space, including viewing lectures remotely while preparing for exams. With respect to fully realizing significant institutional cost-savings, however, more faculty members would need to share and reuse course materials than is currently the case.

We present two studies documenting the effectiveness of the use of a computer simulation with Tutorials in Introductory Physics1 in a transformed college physics course.2 An interactive computer simulation, entitled the Circuit Construction Kit (CCK),3,4 was introduced to investigate its possible impact on students' conceptual understanding. The first study compared students using either CCK or real laboratory equipment to complete two Tutorials on DC circuits. The second study investigated the impact of the simulation's explicit representation for visualizing current flow by removing this feature for a subset of students. In the first study, students using CCK with Tutorials performed slightly better on measures of conceptual understanding compared to real equipment, as measured by exam performance soon after the intervention. In the second study, students using CCK with and without the explicit visualization of current performed similarly to students using real equipment, though on some specific questions we note significant variation in student performance. We discuss the implications of adding (or removing) such representations within computer simulations. Complete listing and access info »

We present studies documenting the effectiveness of using a computer simulation, specifically the Circuit Construction Kit (CCK) developed as part of the Physics Education Technology Project (PhET) [1, 2], in two environments: an interactive college lecture and an inquiry-based laboratory. In the first study conducted in lecture, we compared students viewing CCK to viewing a traditional demonstration during Peer Instruction [3]. Students viewing CCK had a 47% larger relative gain (11% absolute gain) on measures of conceptual understanding compared to traditional demonstrations. These results led us to study the impact of the simulation's explicit representation for visualizing current flow in a laboratory environment, where we removed this feature for a subset of students. Students using CCK with or without the explicit visualization of current performed similarly to each other on common exam questions. Although the majority of students in both groups favored the use of CCK over real circuit equipment, the students who used CCK without the explicit current model favored the simulation more than the other group Complete listing and access info »

The Berkeley Internet Broadcasting System (BIBS) is a lecture webcasting system developed and operated by the Berkeley Multimedia Research Center. The system offers live remote viewing and on-demand replay of course lectures using streaming audio and video over the Internet. During the Fall 2000 semester 14 classes were webcast, including several large lower division classes, with a total enrollment of over 4,000 students. Lectures were played over 15,000 times per month during the semester. The primary use of the webcasts is to study for examinations. Students report they watch BIBS lectures because they did not understand material presented in lecture, because they wanted to review what the instructor said about selected topics, because they missed a lecture, and/or because they had difficulty understanding the speaker (e.g., non-native English speakers). Analysis of various survey data suggests that more than 50% of the students enrolled in some large classes view lectures and that as many as 75% of the lectures are played by members of the Berkeley community. Faculty attitudes vary about the virtues of lecture webcasting. Some question the use of this technology while others believe it is a valuable aid to education. Further study is required to accurately assess the pedagogical impact that lecture webcasts have on student learning. Complete listing and access info »

This paper presents a case study of the development of the South African project Free High School Science Texts (FHSST), an initiative to develop a free high school science text for all teachers and learners in South Africa. The goals of the case study were two-fold: to examine and analyze the practices associated with the successes and challenges encountered by FHSST; and to encourage a participatory, analytical process that will assist other open education projects in thinking about and sharing their practices, processes, and strategies. Beyond its implications for South African education, the FHSST project can serve as a model for peer production of open content, offering insights into planning and decision making around 1) recruiting volunteers; 2) sustaining their participation; 3) using technology to create effective workflow; 4) conducting hackathons; and 5) facilitating teacher trials. Findings from this study offers insights into overall approaches and goals that may prove instrumental across open education projects, serving as a reference for development of assessment tools and resources that may assist open education projects in tracking, sharing, and advancing their learnings and success.
