Two tests of validity were conducted with undergraduate education students on a method of online peer assessment called post and vote. Validity was determined by calculating a Pearson product-moment correlation and corresponding coefficient of determination that compared the average grade assigned by the pre-service teachers with the grade assigned independently by the course instructor. Results of both studies showed that post and vote Web-based peer assessment was valid with these groups, and generalizable to undergraduate classes engaged in similar tasks.

Pedagogical research on Web-based learning and instruction has not kept pace with the proliferation of Web-based courses offered by colleges and universities. Consequently, we encourage the application of the “Seven Principles of Good Practice in Undergraduate Education” (American Association of Higher Education, 1987) to guide the design and implementation of Web-based courses. We offer concrete suggestions on how instructors can apply each principle to maximize the potential of Web-based technologies and promote positive learning outcomes in the virtual classroom.

<p><em>The use of Virtual Globes and Pictometry continues to expand and develop in undergraduate spatial science education. Spatial science undergraduates measured the area of 30 rectangles on the earth’s surface and compared them to Pictometry hyperspectral imagery measurements within a web-based interface and the Google Earth interface compared to ArcGIS Explorer, Map Developers and ArcMap using the ArcMap 10.5.2 interface. An analysis of variance of the absolute mean area errors (p-value of 0.009271) concluded the accuracy of the five area measurements were statistically different at the 95% confidence interval. A Tukey pair-wise test found that the Pictometry and Google Earth methods were more accurate than the ArcGIS Explorer, Map Developers and ArcMap methods. The lowest standard deviation of errors (72.6 sq. ft.) for Pictometry was the most accurate and precise method for on-screen area measurement, followed by Google Earth (SD = 205.0 sq. ft.). The high variation of area measurement error from ArcMap, Map Developers, and ArcGIS Explorer made them less reliable as an alternative to field measurements with ArcMap the worst (SD = 915.1 sq. ft.). The results indicate that Pictometry and Google Earth could both be used to accurately estimate area using on-screen measurements compared to in situ area measurement assessments. </em></p>
