Automated, Web-Based, Second-Chance Homework, Randall W. Hall, Leslie G. Butler, Saundra Y. Mcguire, Sean P. Mcglynn, Gary L. Lyon, Ron L. Reese, Patrick A. Limbach

Randall W. Hall

Procedures and programs for Web-based homework administration were developed and tested. The special feature of the protocol is the option of a "second chance". When a student gives a wrong answer in the weekly homework assignment, a second version of the same question is posed to that student within 48 hours. Both the original and the second versions of the homework are Web-based and automatically graded. More than 90% of the students used the second chance at least once during the semester. More than 60% used this feature for every homework assignment. The second-chance option motivates students to study the ...

The Effect Of Restructuring Student Writing In The General Chemistry Laboratory On Student Understanding Of Chemistry And On Students' Approach To The Laboratory Course , James Andrew Rudd Ii

Retrospective Theses and Dissertations

Many students encounter difficulties engaging with laboratory-based instruction, and reviews of research have indicated that the value of such instruction is not clearly evident. Traditional forms of writing associated with laboratory activities are commonly in a style used by professional scientists to communicate developed explanations. Students probably lack the interpretative skills of a professional, and writing in this style may not support students in learning how to develop scientific explanations. The Science Writing Heuristic (SWH) is an inquiry-based approach to laboratory instruction designed in part to promote student ability in developing such explanations. However, there is not a convincing body ...


Grading The General Chemistry Laboratory: A Constructivist Approach., Barbara Stewart Jan 2001

Grading The General Chemistry Laboratory: A Constructivist Approach., Barbara Stewart

Electronic Theses and Dissertations

Constructivist theories of learning posit that instructors cannot transfer their knowledge to students; students must actively construct their own understanding. The Inter-Chem-Net project uses technology and instrumentation to provide an individualized experience within the large general laboratory course, effectively establishing a constructivist methodology. A grading rubric was developed to communicate course expectations and provide an easy and reliable method of evaluating student work in the general chemistry laboratory. The grading rubric separates the learning outcomes into a checklist of skills associated with each particular grade. This checklist provides detailed feedback for individualized choices of experiments, a key component of the ...
