Correlation, ANOVA and MANCOVA were utilized to test the hypothesis that questions exploiting industry examples would increase discussion interaction volume and exam scores more than using theoretical problems. Demographic factors (age, gender), semester timing, and prior ability were tested for moderation\/mediation impact. Instructional method, professor, course content, assessment rubrics, and learning context were controlled. The treatment consisted of enhancing all discussion and examination questions from the materials and assessments to approximate authentic industry scenarios. A statistically significant model was validated, using exam question types as a factor, and a count of online discussion interactions (as a covariate), to measure problem-based learning effect on exam score.<\/p>","DOI":"10.4018\/jicte.2011040106","type":"journal-article","created":{"date-parts":[[2011,10,19]],"date-time":"2011-10-19T12:27:00Z","timestamp":1319027220000},"page":"57-68","source":"Crossref","is-referenced-by-count":5,"title":["E-Learning Effectiveness in a Quantitative Course"],"prefix":"10.4018","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4333-4399","authenticated-orcid":true,"given":"Kenneth David","family":"Strang","sequence":"first","affiliation":[{"name":"APPC Market Research, USA; State University of New York, USA; University of Technology, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"issue":"4","key":"jicte.2011040106-0","first-page":"163","article-title":"An assessment of web-based homework in the teaching of college algebra.","volume":"14","author":"M.Affouf","year":"2007","journal-title":"The International Journal for Technology in Mathematics Education"},{"key":"jicte.2011040106-1","author":"D.Ausubel","year":"1963","journal-title":"The psychology of meaningful verbal learning"},{"key":"jicte.2011040106-2","doi-asserted-by":"publisher","DOI":"10.1002\/acp.1513"},{"key":"jicte.2011040106-3","author":"R.
