Efficient learning from web resources can depend on accurately assessing the quality of each resource. We present a methodology for developing computational models of quality that can assist users in assessing web resources. The methodology consists of four steps: 1) a meta-analysis of previous studies to decompose quality into high-level dimensions and low-level indicators, 2) an expert study to identify the key low-level indicators of quality in the target domain, 3) human annotation to provide a collection of example resources where the presence or absence of quality indicators has been tagged, and 4) training of a machine learning model to …
Self-Directed Learning In Problem-Based Learning Versus Traditional Lecture-Based Learning: A Meta-Analysis, Heather Leary
Self-Directed Learning In Problem-Based Learning Versus Traditional Lecture-Based Learning: A Meta-Analysis, Heather Leary
Heather Leary, Ph.D.
Problem-based learning is a student-centered, inquiry-based approach that builds problem-solving skills. Reviews of problem-based learning, as compared to traditional lecture-based learning, report modest positive gains in cognitive outcomes. Many metaanalyses have been conducted to analyze the effectiveness of problem-based learning, but none have examined self-directed learning in the context of problem-based learning. The purpose of this study was to conduct a meta-analysis across all disciplines examining the extent to which problem-based learning engenders self-directed learning compared to a lecture-based approach. This study used a random effects model meta-analysis using 75 outcomes from 38 studies. Results indicated a statistically significant, z(74) …

Beyond Research: Opencourseware In The Institutional Repository, Heather Leary, Brett Shelton, Marion Jensen
Beyond Research: Opencourseware In The Institutional Repository, Heather Leary, Brett Shelton, Marion Jensen
Heather Leary, Ph.D.
Presentation given at the 2009 LITA National Forum in Salt Lake City, Utah on archiving OpenCourseWare in the Institutional Repository. The main function of OpenCourseWare is to provide open access to collections of educational materials used in formal courses. The main function of an Institutional Repository is to collect, preserve, and disseminate intellectual output of an institution. Since OCW is a significant portion of the intellectual output of a university, archiving OCW in an institutions repository seems a perfect marriage of means and opportunity.

The New Science of Learning: Cognition, Computers and Collaboration in Education deftly explores the multiple relationships found among these critical elements in students’ increasingly complex and multi-paced educational experience. Starting with instructors’ insights into the cognitive effects of digital media—a diverse range of viewpoints with little consensus—this cutting-edge resource acknowledges the double-edged potential inherent in computer-based education and its role in shaping students’ thinking capabilities.

While much progress has been made on the technical design and development of digital libraries, much less is known about how and why education digital library content and associated tools can support and enhance the activities of educators in their professional work. This article elaborates a conceptual framework that characterizes teachers' practices when using online learning resources (called 'teaching as design'), and a professional development model aimed at increasing teachers' capacity for designing learning activities in the context of authentic practice. Findings from two workshop implementations showed positive impacts on teachers' knowledge, attitudes, and subsequent behaviours using online learning resources. …
Developoing A Review Rubric For Learning Resources In Digital Libraries, Heather Leary, Sarah Giersch, Andrew Walker, Mimi Recker
Developoing A Review Rubric For Learning Resources In Digital Libraries, Heather Leary, Sarah Giersch, Andrew Walker, Mimi Recker
Heather Leary, Ph.D.
Over the past 10-15 years, educational digital libraries (DLs) have acquired online learning resources of varying levels of granularity (e.g., from images to entire lessons) and of varying sources of authorship (e.g., grant-funded subject matter experts; K12 teachers; graduate students). The challenge is to balance collecting and providing access to online learning resources while maintaining a level of resource quality that distinguishes DLs from internet search engines. In response, many educational DL builders have established review rubrics.
Re-Framing Information Literacy: Problem-Based Learning As Informed Learning, Wendy Holliday, Anne Diekema, Heather Leary
Re-Framing Information Literacy: Problem-Based Learning As Informed Learning, Wendy Holliday, Anne Diekema, Heather Leary

This study explores an online information literacy module that uses problem-based learning (PBL). The goal was to enable students to experience information literacy in a richer way, by moving away from a focus on locating information sources to one of information use in the construction of knowledge. A content analysis of the research journals and reflection papers of students (N = 15) in a distance education school library media administration endorsement program suggests that PBL was an effective approach for some students, but not others. Some students were motivated by working on authentic problems, and at least half the …

The National Science Foundation (nsf.gov) has funded a large initiative to catalog collections of high-quality online resources into the National Science Digital Library (nsdl.org). The mission of the NSDL is to help improve education for all teachers and students. The purpose of this module is to help you find high-quality online resources, learn strategies for incorporating them into a free software tool called the Instructional Architect, and use these projects in an instructional situation. In this module, you will learn to access online resources and to use tools to help solve instructional or learning problems or issues that you currently …

Assessing the quality of online educational resources in a cost effective manner is a critical issue for educational digital libraries. This study reports on the approach for extending the Open Educational Resource Assessments (OPERA) algorithm from assessing vetted to peer-produced content. This article reports details of changes to the algorithm, comparisons between human raters and the algorithm, and the extent the algorithm can automate the review process.

Expert Versus Novice Tutors: Impacts On Student Outcomes In Problem-Based Learning, Heather Leary, Andrew Walker, M. Fitt, Brett Shelton
Expert Versus Novice Tutors: Impacts On Student Outcomes In Problem-Based Learning, Heather Leary, Andrew Walker, M. Fitt, Brett Shelton
Heather Leary, Ph.D.
The tutor is an essential part of problem based learning (PBL). However, tutor characteristics and role are inconsistent. Meta-analysis was used to investigate both the role and training of PBL tutors as moderators of student learning. Weighted effect sizes were calculated on student outcomes with a modest favorable overall effect size for PBL; a vote count shows favorable results as well. Results indicate a mixture of peers and instructors do best when compared to peers and instructors alone. Tutor training appears to make a difference by itself, but when considered with tutor background, tutor training does not appear to moderate …
