Effectiveness Of Training On Algorithms Versus Notation For Indirect Addressing Comprehension , Robert Dee Franks

Retrospective Theses and Dissertations

This study compared two units of instruction for overcoming difficulties of beginning programmers in understanding and implementing strategies of indirect addressing. One of the units emphasized the algorithms in which indirection was used, whereas the other unit emphasized indirect notation. Both instructional units were delivered by computer to two introduction to Pascal programming classes. Students in each class were randomly divided so that each student used one or the other of the two units;These units were used prior to and were supplementary to three lectures covering indirect notation. The effectiveness of the units were determined by two posttests. One ...

Estimating Course Difficulty , Daniel James Mundfrom

Retrospective Theses and Dissertations

The difficulty level of college courses has been identified as a value which varies across courses. A sample of fifty (50) introductory-level college courses was selected and four different measures of course difficulty, (1) perceived difficulty, (2) perceived amount of work, (3) average grade awarded, and (4) average ACT composite of enrolled students, were calculated for each course. The difficulty estimates were examined for consistency for each measure individually, over time, and in comparison with the others. Correlation analysis, multiple regression, factor analysis, hierarchical cluster analysis, and analysis of variance procedures were used. The four measures were combined into one ...
