Badeau, Ryan C. – ProQuest LLC, 2017
This thesis explores two case studies into the use of short answers and self-explanation to improve student learning in physics. The first set of experiments focuses on the role of short answer questions in the context of computer-based instruction. Through a series of six experiments, we compare and evaluate the performance of computer-assessed…

Liu, Min; Bera, Stephan – Educational Technology Research and Development, 2005
In this study, we examined the use of cognitive tools provided in a problem-based hypermedia learning environment for sixth graders. Purposes were to understand how the built-in tools were used, and if tool use was associated with different problem-solving stages. Results showed that tools supporting cognitive processing and sharing cognitive load…

Chen, Gwo-Dong; Liu, Chen-Chung; Ou, Kuo-Liang; Lin, Ming-Song – Innovations in Education and Training International, 2001
Describes how to design a Web portfolio system that teachers can use in learning assessment. Evaluation of the Web portfolio system by students indicates that the applied technologies help students control their learning processes through developing portfolios. Students also believe Web portfolios serve as an effective communication channel and…
