Training Reduces The Drawing Detriments Associated With Categorical Perception, Larissa F. Arnold Jan 2018

Training Reduces The Drawing Detriments Associated With Categorical Perception, Larissa F. Arnold

Graduate Theses and Dissertations

Previous research suggests that categorical perception may interfere with a novice artist’s ability to accurately draw simple shapes. Specifically, when asked to draw two shapes of slightly different sizes, participants tend to exaggerate the categorical difference between the two and draw the small shape too small. Similarly, participants tend to draw oblique angles more oblique than they should be when they are close to perpendicular or overlapping. The current set of experiments investigated whether these categorical errors could predict participants’ drawing ability on a more complex drawing task. A simple linear regression revealed that categorical errors in angle could ...

Iowa Agricultural Educators' Current Grading Practices And Perceptions Of Standards-Based Grading, Jenny Ann Lichty Jan 2014

Iowa Agricultural Educators' Current Grading Practices And Perceptions Of Standards-Based Grading, Jenny Ann Lichty

Graduate Theses and Dissertations

Research on grading reveals that grading practices have not changed much since they were first introduced. However, educators are now learning about a newer grading approach that evaluates student performance based on clearly defined learning standards. Standards-based grading (SBG) looks to more accurately communicate student knowledge by assessing and reporting each student's mastery based on clearly defined learning standards. While still rather new, research on standards-based grading is limited and very little has been conducted at the secondary level. Even less research has been conducted on SBG and grading practices of career and technical education teachers.

The purpose of ...
