Validity of Web-based Peer Assessment through Networked Workshop Instruction:

The study examined the reliability and validity of web-based peer assessment through a case study on networked workshop instruction, an instructional method that emphasizes presentation, discussion, peer feedback, and knowledge construction. In workshop instruction, peer assessment was used to evaluate students ’ performance. Twenty four computer science graduate students enrolled in a course “Web and Database Integration ” and were assigned to nine teams. Each team was instructed to design a web-based system capable of performing certain functions. Functioning similar to how researchers and scientists would in a workshop, participants orally presented design concepts and web-based peer assessment was conducted to increase critical feedback during design. Three design products and qualitative comments from teachers were presented to demonstrate the students ’ high quality performances. Statistical analyses confirmed the reliability and validity of web-based peer assessment in networked workshop instruction
