The Effect of Roughness Elements on the Magnus Characteristics of Rotating Spherical Projectiles

Description: Thirty trials of each of three roughness conditions were examined. The first condition consisted of a baseball pitched so that two of the roughness elements opposed the flow. The second condition consisted of a pitched baseball with four of the roughness elements opposing the flow. The third consisted of a pitched uniformly rough sphere. The conclusions were that roughness elements increase horizontal flight deviations when a baseball rotates about a vertical axis; roughness elements on the sur… more

A Comparison of Two Methods of Training Naive Users in the Use of a Microcomputer System

Description: The problem addressed in this study is the need for efficient and economic methods to train naive college students to operate microcomputers as a necessary step in their acquisition of computer proficiency. Two methods of training were compared. These were training by live demonstration and training by videotape. These methods were considered economically viable because each could be presented in a classroom and neither required a one-to-one student-to-computer or student-to-tutor ratio. Four … more

Errors in Looping and Assignment by Novice Assembly Language Programmers

Description: The problem with which this investigation is concerned is an analysis of errors in looping and assignment made by novice assembly language computer programmers. This analysis is made after subjects write three computer programs. The verbal definition of the problem for each program specifies, without naming, either a for, while, or repeat looping structure. The purposes of the study are the following; to determine whether using the appropriate looping structure is related to writing a correct p… more

The Use of Learning Theory in the Application of Artificial Intelligence to Computer-Assisted Instruction of Physics

Description: It was the purpose of this research, to develop and test an artificially intelligent, learner-based, computer-assisted physics tutor. The resulting expert system is named ARPHY, an acronym for ARtificially intelligent PHYsics tutor. The research was conducted in two phases. In the first phase of the research, the system was constructed using Ausubel's advance organizer as a guiding learning theory. The content of accelerated motion was encoded into this organizer after sub-classification accord… more

The Use of Computers in the Administration of Non-Public Schools

Description: The purposes of this study were (1) to identify the uses of computers in non-public school administration and (2) to determine what factors affect the usage of computers in non-public school administration. An eight per cent (1525 schools) sampling of all nonpublic secondary and elementary in the United States was sent questionnaires. Eight hundred and seventy two (57 per cent) were returned. Some major findings of this study were that 36 per cent of all non-public schools use computers for adm… more
