Using an Online, Self-Diagnostic Test for Introductory General Chemistry at an Open University

Abstract

A simple, online, self-diagnostic tool has been developed to allow students to independently and quickly measure their potential of success in a first-year general chemistry course. The online tool employs well-established performance predictors in areas such as student educational background, conceptual basics, critical thinking, mathematical skills, and problem-solving skills. This particular self-diagnostic test shows a strong correlation coefficient between the test score and the overall final grade in the course. Careful observation of correlations between sections of the diagnostic test and various components of the course suggest further refinements to the instrument and the advice we give students.

On the development and assessment of a computer-based learning and assessment environment for the transition from lower to upper secondary chemistry education

“…They do not feel worry or concern when working with tests operated by computers or online testing platforms. Kennepohl et al (2010) have documented high levels of predictive power for online self-diagnostic assessment with regard to later success in examinations. Ryan (2013) even suggested the development of self-assessment multiple choice questions for the promotion of chemistry learning.…”

Effect of a Concurrent Enrollment Preparatory Course on Student Achievement and Persistence in General Chemistry

“…Though many placement methods using mathematical and chemical principles have been developed, − the complex array of predictive success factors in general chemistry , have led to expected inaccuracies in placement . Students identified as needing preparatory courses often perform as well as students who are not .…”

Testing in the Time of COVID-19: A Sudden Transition to Unproctored Online Exams

“…We have used no-stake online tests for several years as a precourse diagnostic 13 to obtain performance data to support interventions persuading students to adopt metacognitive learning strategies, 14 and online practice tests are now delivered via an online homework system in some courses. 15 Frequent, low-stake quizzes are also delivered online by many instructors.…”
