Govindarajoo, Geeta; Lee, June Y.; Emenike, Mary Elizabeth – Journal of Chemical Education, 2021
Digital badges are credentials earned via a digital presentation to demonstrate the mastery of a technique. They have been utilized in General Chemistry laboratory courses as an assessment tool and to document students' development of a skill. A digital badge assignment was developed for thin layer chromatography (TLC) and integrated into a…

Bongers, Amanda; Beauvoir, Berthorie; Streja, Nicholas; Northof, Georg; Flynn, Alison B. – Chemistry Education Research and Practice, 2020
In chemistry, novices and experts use mental models to simulate and reason about sub-microscopic processes. Animations are thus important tools for learning in chemistry to convey reaction dynamics and molecular motion. While there are many animations available and studies showing the benefit of learning from animations, there are also limitations…

Cosio, Mario N.; Williamson, Vickie M. – Journal of Science Education and Technology, 2019
The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date…

Casselman, Brock L.; Atwood, Charles H. – Journal of Chemical Education, 2017
In a first-semester general chemistry course, metacognitive training was implemented as part of an online homework system. Students completed weekly quizzes and multiple practice tests to regularly assess their abilities on the chemistry principles. Before taking these assessments, students predicted their score, receiving feedback after…

Kim, Beaumie; Pathak, Suneeta A.; Jacobson, Michael J.; Zhang, Baohui; Gobert, Janice D. – Journal of Science Education and Technology, 2015
Model-based reasoning has been introduced as an authentic way of learning science, and many researchers have developed technological tools for learning with models. This paper describes how a model-based tool, "BioLogica"™, was used to facilitate genetics learning in secondary 3-level biology in Singapore. The research team co-designed…

Golick, Douglas A.; Heng-Moss, Tiffany M.; Steckelberg, Allen L.; Brooks, David. W.; Higley, Leon G.; Fowler, David – Journal of Science Education and Technology, 2013
The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture…

Revell, Kevin D. – Journal of Chemical Education, 2014
Three emerging technologies were used in a large introductory chemistry class: a tablet PC, a lecture capture and replay software program, and an online homework program. At the end of the semester, student usage of the lecture replay and online homework systems was compared to course performance as measured by course grade and by a standardized…

Donovan, William – Journal of Computers in Mathematics and Science Teaching, 2008
This paper reports the findings of a study of student attitudes and student improvement in conceptual understanding using conceptests with an electronic response system in lecture courses. Students and instructors valued the feedback and interaction that the response system afforded. For a majority of the chemistry topics studied, student…

Milkent, Marlene M.; Roth, Wolff-Michael – Journal of Research in Science Teaching, 1989
Investigated were the effects of interactive computer-generated homework on unit tests, a final examination, and a comprehensive test given near the end of a Physical Science I course. The results indicated that the use of the homework reduced the effectiveness of the American College Test scores as a predictor of course achievement. (YP)
