This study evaluated three tutorial modules, equivalent in content but different in mode of presentation, for introducing elementary statistics concepts. In a single session, fifty-seven college students participated in one of four randomly assigned conditions: paper-and-pencil, basic computerized, computerized multimedia, or control group. Participants completed a demographic questionnaire, a survey of attitudes toward math and computers, the Personal Need for Structure (PNS) scale, a basic math proficiency test, an evaluation of assigned module, and a post test statistical comprehension test. The results suggested that participant evaluations of the modules were comparably positive. Although participants in the modules performed significantly better on the statistical comprehension posttest than those in the control group, there were no significant differences between the modules. The basic computerized module took significantly less time to complete than the other modules. Computer-mediated instructional applications are readily employed as teaching tools for a range of academic subjects including animal behavior [1], business administration, computer science [3], literature [4], psychology [5, 6], social science [7], and social work [8]. Among the ancillary benefits of instructional software are to present topics comprehensively, provide practice sessions outside the classroom, and remediate academic skills [9]. Computer-assisted interactive 411 Ó 2000, Baywood Publishing Co., Inc.instructional applications also promote "active learning" by providing options to navigate the sequence of the topics, explore and review the material, control the pace of presentation, and request immediate feedback [10]. In addition, computerized interactive applications reinforce higher-order conceptual and critical thinking by engaging students in inquiry and problem solving [4,11,12]. Lastly, computer-mediated instructional applications assist to confidentially track student activity, collect and store responses, and assess performance, thus offering instructors more time to interact with students [13,14].The scientific literature provides abundant empirical evidence to support the effectiveness of computer-based instruction. Meta-analysis found that computerassisted instruction displayed strong effect sizes, ranging from .25 to 1.05 [15,16]. Research also suggested that effect sizes for computer-mediated educational applications were equivalent or better than conventional teaching methods (e.g., classroom instruction) for improving student academic performance [2,16]. Many of the research findings were based on instructional software limited to basic elements of text, graphics, and linear navigation. Recent developments in computer technology, such as computer-mediated multimedia, can provide new opportunities for teaching and learning.
