The importance of providing students with feedback on their learning is well documented. However, providing feedback to individual students is often impossible and time consuming. To address the need for a more efficient and effective approach to giving individualized feedback to students, a Wiley PLUS web-based homework (WBH) system that provides automated grading to individual students was piloted in a physics class for this study. Thus, this paper presents results on the effects of the use of Wiley PLUS web-based automated grading homework system in a first year introductory Engineering Physics course. The study investigated how the Wiley PLUS web-based homework system impacted on the students' paper based tutorial mock test, mid-term-test and Final Integrated Summative Assessment (FISA) performance. The study was informed by Laurilland's educational media conversational framework for teaching and learning supporting the 'interactive activity' learning process using Web-based homework as an adaptive medium. Both quantitative and qualitative methods of collecting data were used in this study. A comparison between students' performance on the Wiley PLUS online web-based homework, paper based written tutorial mock test, mid-term test and FISA was done to evaluate if there was a correlation in students' performances. Additionally, during the final class of the semester, Chemical Engineering Extended Curriculum Program students who enrolled for the introductory Physics course responded to a survey and participated in focus group interviews to gauge their perceptions and experiences on the use of the Wiley PLUS web-based system. Quantitative data was analysed using descriptive statistics and inferential statistics, while qualitative data was analysed using an inductive strategy. Results indicated that the Wiley PLUS WBH system enhanced students' learning and collaboration among learners. There was a strong positive correlation between students' WBH marks and marks students' obtained in the tutorial mock test, mid-term test and the FISA. [ABSTRACT FROM AUTHOR]
