    CAL evaluation: Future directions

    Formal, experimental methods have proved increasingly difficult to implement, and lack the capacity to generate detailed results when evaluating the impact of CAL on teaching and learning. The rigid nature of experimental design restricts the scope of investigations and the conditions in which studies can be conducted It has also consistently failed to account for all influences on learning. In innovative CAL environments, practical and theoretical development depends on the ability fully to investigate the wide range of such influences. Over the past five years, a customizable evaluation framework has been developed specifically for CAL research. The conceptual approach is defined as Situated Evaluation of CAL (SECAL), and the primary focus is on quality of learning outcomes. Two important principles underpin this development. First, the widely accepted need to evaluate in authentic contexts includes examination of the combined effects of CAL with other resources and influential aspects of the learning environment. Secondly, evaluation design is based on a critical approach and qualitative, case‐based research. Positive outcomes from applications of SECAL include the easy satisfaction of practical and situation‐specific requirements and the relatively low cost of evaluation studies. Although there is little scope to produce generalizable results in the short term, the difficulty of doing so in experimental studies suggests that this objective is difficult to achieve in educational research. A more realistic, longer‐term aim is the development of grounded theory based on common findings from individual cases

    Facilitating Classroom Economics Experiments with an Emerging Technology: The Case of Clickers

    The authors discuss how they used the audience response system (ARS) to facilitate pit market trading in an applied microeconomics class and report the efficacy of the approach. Using the ARS to facilitate active learning by engaging students in economics experiments has pedagogical advantages over both the labor-intensive approach of pencil-and-paper and the capital-intensive route of relying on networked or on-line computer labs which oftentimes preclude or restrict face-to-face student interactions. Thus, the new method of conducting experiments represents an added advantage on top of such conventional functions as taking attendance and administering quizzes of this increasingly popular classroom technology.Teaching/Communication/Extension/Profession,

    AN ANALYSIS OF ONLINE EXAMINATIONS IN COLLEGE COURSES

    This research evaluates the use of online examinations in college courses from both instructor and student perspectives. Instructional software was developed at Kansas State University to administer online homework assignments and examinations. Survey data were collected from two classes to measure the level of student support for online examinations. The determinants of the level of student support for online testing were identified and quantified using logistic regression analysis.Teaching/Communication/Extension/Profession,

    Making Large Classes Small(er): Assessing the Effectiveness Of a Hybrid Teaching Technology

    This paper examines learning outcomes in a one-semester introductory microeconomics course where contact time with the instructor was reduced by two-thirds and students were expected to view pre-recorded lectures on-line and come to class prepared to engage in discussion. Students were pre-and post-tested using the Test of Understanding in College Economics (TUCE - 4). Learning outcomes as measured by the change in test scores are found to be as good as or better than calibrating data for groups assessed using the TUCE - 4. In addition to being a more enjoyable course for the instructor, the course design can be part of a more self-directed curriculum that uses available resources more efficiently to achieve similar learning objectives to a lecture-based introductory course.active learning, assessment, computer-assisted instruction, introductory microeconomics
