Criterion Analysis: a Factorial Study of School Grades

Bryant, Norman Dale January 1951 (has links)
It is the purpose of this paper to present a technique for analyzing grades and other criteria, and by so doing, arrive at the factors which will explain the variance of the criteria. This technique is not new; however, it has received very little use. The technique is simply that of factor analyzing a matrix of intercorrelations of variables which include the grades and related measures necessary to define the factors. The selection of the related variables is the crucial problem.

A study of factors affecting the efficiency of maturity separation of peas by sodium chloride brine flotation

Chavasit, Visith 20 December 1984 (has links)
The problem in green pea grading system by using brine flotation is loss of some less mature peas (generally regarded as higher in quality and price) in the sinker fraction (lower quality). Green peas were sampled from the production line as follows: (1) blanched but ungraded peas, (2) floater fraction, and (3) sinker fraction. Peas from the floater and sinker fractions were tested using the standard brine flotation test (United States Standards for Grades of Frozen Peas, 1959). Using sodium chloride salt brine as the separation medium, the blanched but ungraded peas were used to test the effect on percent floaters caused by: (1) change in brine concentration, (2) change in brine temperature, (3) change in pea temperature. Again, the blanched but ungraded peas were used to test the effect of underskin air on percent floaters, using sucrose syrup as the separation medium. The relationships between change in percent floater peas and maturity of the floater and sinker fractions were determined by using Alcohol Insoluble Solids (AIS) analysis as the maturity reference method. The nature of problem was identified, when a high percent (44.9%) U.S. Fancy grade floaters was found in the sinker fraction from the factory. The study showed that the percentage of floaters was significantly (p=0.05) influenced by brine concentration, brine temperature, pea temperature, and retention of air under the skin of the peas. Regression analysis of the data for the first three factors indicated that rate of change in percent floaters was greatest with brine concentration, and least with pea temperature. The change in maturity of floater and sinker fractions as determined by AIS analysis showed a close positive relationship between the change in percent floaters produced by change in the treatment conditions. Again, AIS results showed that residual underskin air in the intact blanched peas significantly affected the accurate separation by a false increase in buoyancy of borderline maturity peas (AIS was in between floater's and sinker's) in the flotation process. The underskin air factor was the least important factor affecting percent floaters when compared with the other factors of brine concentration, brine temperature, and pea temperature. / Graduation date: 1985

Development of CAD Platform Independent Software for Automatic Grading of Technical Drawings

Ingale, Sanchit Sanjay 15 September 2017 (has links)
Spatial visualization is the ability of an individual to visualize an object mentally and understand its spatial orientation. It plays an important role in engineering. There have been multiple works that show that spatial visualization skills can be improved with the right training. Creating technical drawings requires mental manipulation and visual thinking. Strong spatial visualization abilities are required for such a mental process. To train students in this process and to improve their spatial skills, Professor Diana Bairaktarova conducted a class in spatial visualization for freshmen in engineering at Virginia Polytechnic Institute and State University. The class consisted of 169 students from different engineering disciplines. One of the major pedagogical techniques used in the class was to give students three assignments on drawing sectional views of mechanical objects with a pre-defined cutting plane. All three assignments had the same six mechanical objects to assess their improvement through the class. Students were not given feedback after completion of each assignment. They were asked to do the first assignment at the beginning of the course, the second assignment during the middle of the semester and the final assignment towards the end of the semester. The students were given instructions on how to draw the 2D sectional views. The assignments were then graded by the teaching assistants for the class and the improvement of the students through the semester was recorded. Assignments were graded manually by two different raters using a pre-defined grading rubric. An inter-rater reliability was established between the graders. There were drawbacks to this process. It was extremely time consuming since there were more than 500 assignments to be graded by the teaching assistants. Also, to establish inter-rater reliability, the assignments had to be graded twice. The process would have been more efficient if there was a software that could automate the grading process. Also, this would eliminate the need to establish an inter-rater reliability. This research aims at developing a software for automatic grading of the technical drawings. The software gives students' feedback on the drawings describing their mistakes. This would give a more complete learning experience as the students would get a better understanding of the internal details of the object with the help of the feedback they are getting. In addition, the software is independent of the CAD platform used to create the drawings. The instructor can also upload a batch of images that can be processed by the software at once. The grading rubric that was used for manual grading can be implemented in the software. The software uses Image processing and Computer Vision toolboxes in MATLAB which enables the comparison between the submitted technical drawing and the source (solution) drawing. The software is currently developed for simple geometries with less complicated features as it is being employed in a course where students are new to CAD environment. Students can also use this software as an interactive learning tool as they create 3D models and sectional views of mechanical objects. The proposed software reduces the amount of effort put in by faculty on grading the assignments. It also gives students feedback on the drawings, making it an interactive tool which improves the learning experience. This software can be a powerful pedagogical tool to improve spatial visualization skills. / Master of Science
