While online and face-to-face (F2F) courses have been compared in numerous studies, there has been a lack of focus on online chemistry courses. This study was conducted to compare the success of students instructed in an online or F2F general chemistry course for non-majors. One hundred forty six exam questions were categorized according to…

It is a common complaint among teachers that students forget what they have learned soon after taking a test. The phenomenon is seen in both secondary and undergraduate chemistry courses. This study examines the length of time after a test that students in three different chemistry courses (undergraduate nursing, nonscience majors, and high school…

Determining students' knowledge structure is important for assessing what a learner knows about a domain of knowledge. Traditional assessment methods are not always appropriate for exploring students' knowledge structure and changes during the learning period. This study investigates how the existing knowledge structure of the learners interacts…

This study examined the cognitive development of students enrolled in three levels of freshman chemistry courses and focused on changes in spatial ability over time. Results indicate that performance on general Piagetian-type tasks, including spatial visualization, can be refined through educational intervention. Concludes that students appear…
