My research: Screencasting feedback in online learning



Problem: Written feedback in online learning is often not personalized. The distant nature of online learning makes it difficult for students to develop rapport with their instructors. Attrition rates in online learning courses are higher than on ground.
Purpose: To determine whether screencasting feedback in online learning influenced students’ grades and course attrition.

Research questions:
1. To what extent, if any, does screencasting as a form of instructor feedback influence online students’ course grades (discussion posts, tests, final)?
2. To what extent, if any, does screencasting as a form of instructor feedback influence online course attrition?
Sample
Two sections of an undergraduate C++ online course taught by the same professor during separate times.The instructor was experienced in online learning. Kaltura was used as the screencasting software. A total of 59 Computer Information Systems online students. 28 participants in the experimental group. 31 participants in the control group.
Methods & Instruments
Quasi-experimental quantitative study. Multiple Regression to determine the correlation between course performance and attrition in both the control and experimental groups. The statistical assumptions were checked using histograms P-P plots.
Results for Research Question 1
Significance of 0.972,which indicates a failure to reject the null hypothesis. There was insufficient evidence to support the existence of a significant difference between screencasting feedback and online students’ grades, which were operationalized by calculating the overall average.
Results for Research Question 2
Significance of 0.898, which indicates a failure to reject the null hypothesis. There was insufficient evidence to support there being a significant difference between screencasting feedback in an online course and course attrition.
Implications
Screencasting had no significant influence over traditional feedback. This research failed to make a connection between screencasting and course grades or attrition.
Recommendations for future research
Further research on the potential solutions to the problem of course attrition in online learning. Future research will a larger sample size and the same type of LMS. Gathering qualitative data. Other academic levels, such as high school as a comparison.
