Comparative and non comparative evaluation in educational technology
The document summarizes two studies that evaluated educational technology: The first was a comparative study that examined student learning and perceptions in a horticulture course delivered either via live instruction or web-based instruction. Surveys found that while both groups improved their quiz scores, the increase was greater for students who received live instruction. The second was a non-comparative study that investigated how learning styles, computer skills, and prior online course experience influenced knowledge gain for adults in an online special education course. The study found that identifying individual differences like learning styles and computer abilities can help optimize online course design and address diverse student needs.
Comparative and non comparative evaluation in educational technology
- 1. Comparative and non-comparative evaluation in educational technology Comparative study: Title: A COMPARISON OF THE PERFORMANCE AND PERCEPTIONS OF STUDENTS RECEIVING LIVE VERSUS WEB-BASED HORTICULTURAL INSTRUCTION Author: IGINO TEOLIS, B.Sc.(Agr.), M.Sc. Purpose of the study: examine whether the level of student learning in horticulture was equivalent in both web-based and traditional live instruction and to compare perceptions of students towards different modes of instruction. Instrument:surveys, A pre-course survey was distributed within the first week of the course.All students were asked to complete a similar survey (post-course survey) during the last class of the semester or after completing the final exam. Evidence:Both web-based and traditional course students had greater percentages of correct quiz answers in the post-course survey than in the pre-course survey. The increase in quiz score was greater for the traditional course students than for the web-based students. Non-Comparative study: Title:IMPACTS OF LEARNING STYLES AND COMPUTER SKILLS ON ADULT STUDENTS LEARNING ONLINE Author: Salih RAKAP Purpose of the study:investigated the influences of learning styles/preferences, prior computer skills and experience withonline courses on adult learners knowledge acquisition in a web-based special education course.
- 2. Instrument:The VARK learning preference questionnaire was selected to evaluate learning preference of adult students because it is very easy and quick to complete and available online. Evidence:The findings of current research further support the necessity of identifying individual differences (e.g., learning styles and computer skills) of online course participants in order to optimize instructional design and strategies, maximize learning opportunities for students enrolling in online programs and courses, and address their diverse needs for learning.
