Silencing Ivan Illich \u3cem\u3eRevisited\u3c/em\u3e: A Foucauldian Analysis of Intellectual Exclusion
No full textOriginally published in 1993, Silencing Ivan Illich fell out of print when the original publisher went out of business in 1995. The author, David Gabbard, states that the book was pivotal in the evolution of his understanding of schools. Delving into Foucault’s work to forge a methodology, he wanted to understand the discursive (symbolic) forces and relations of power and knowledge responsible for the marginalization of Ivan Illich from educational discourse. In short, Illich was “silenced” for having committed the heretical act of denying the benevolence of state-enforced, compulsory schooling. In Silencing Ivan Illich Revisited, Gabbard revisits the text as a means of opening the question of what schools should be. Inspired by Slavoj Zizek’s call for a Positive Universal Project, the book provides an alternative vision of what our species ought to be doing in the name of collective learning.https://scholarworks.boisestate.edu/fac_books/1525/thumbnail.jp

Effects of statically performed toe touch stretches on torque production of the hamstring and quadriceps muscle groups
No full textTypescript (photocopy).Stretching used as part of a warm up routine for later performance has become not only popular but also recommended by physical educators. Warm up stretches are thought to enhance performance and reduce the incidence of soft tissue injuries occurring in the subsequent performance. However almost no evidence exists as to the effect of these stretches upon the torque production of these muscles in a later performance. It was the purpose of this study to investigate the effects of warm up stretches upon torque production. Between the pre- and post-test conditions on the treatment day, subjects (n=24) performed three 30s static toe touches interspersed with equal rest intervals. On the control day subjects spent the equivalent period of time in a relatively inactive state. They were allowed to stand and walk, but instructed to refrain from stretching. On two consecutive days at approximately the same time, subjects were tested for maximum torque production at four movement speeds (0, 60, 150, & 240 ��/s) using a Cybex II isokinetic exercise device. Five minutes of no load cycling preceded each pre-test. Each test consisted of four maximum knee extension/flexion cycles. All torque and position recordings were made at a chart paper speed of 25mm/s. Peak torque and the amount of time required to attain peak torque were digitized from the chart recordings using a Neumonics digitizer. Torque at 45�� were also obtained from the strips. For each subject 0�� was determined at full extension prior to the pre-test. Means values obtained from the two middle cycles for all variables were used for analysis. Hamstring/quadriceps ratios (H/Q) were computed for peak torques and torques at 45��. Peak torques for both the hamstring and quadriceps muscles were found to reduce as the speed of movement increased, but H/Q values were unaffected by speed. None were effected by stretch. Torques measured at 45�� and their ratio were also unaffected by stretch, but the ratios were speed dependent. No evidence was found to suggest that stretch when used as part of a warm up routine provided any facilitory or inhibitory affect upon torque production in a subsequent performance
Contextual interference effect in motor skill learning : examination of attention demands
No full textVitaMajor subject: KinesiologyThe contextual interference (Cl) effect refers to the important differences observed between high Cl (e.g., random schedule) and low Cl (e.g., blocked schedule) practice in motor skill learning, in which acquisition performance suffers but retention performance is facilitated by high Cl practice. Explanations based on forgetting and elaborative processing both intimate that the additional cognitive activity required during high Cl practice contributes to the emergence of this effect. The purpose of the present study was to investigate the attention demands associated with the two practice conditions by using a dual-task method. The primary task was to learn three key-pressing patterns with three segmental timing requirements for each pattern in either random or blocked practice schedule. In Experiment 1, an auditory stimulus (i.e., high or low tone) was presented unpredictably during the practice trials. Subjects were required to concentrate on the primary task during the acquisition while also monitoring the number of the high tones. The acquisition, which consisted of three blocks of 18 trials on the timing task, was followed by 10-min and 24-hour delayed retention tests. Results showed the typical Cl effect with retention performance being facilitated by the random practice, even though acquisition performance was superior for the blocked practice. Random practice subjects produced more errors on the secondary task, indicating that greater attentional demands were required during random practice. However, a cautious interpretation of these data was necessary because degraded primary task performance was observed for the dual-task condition, compared with the control condition. Experiment 2 attempted to eliminate this problem, but failed to replicate the findings on the secondary task performance. Using a discrete reaction time (RT) probe task in Experiment 3, the findings from Experiment 1 were replicated, as well as eliminating the primary task problem observed in Experiment 1. The data from Experiment 3 are consistent with the predictions from the elaboration view. In Experiment 4, a modified practice condition was employed to directly test the forgetting hypothesis. The results provide support for the contribution of a reconstructive process to random practice. These data are discussed with respect to the contribution of forgetting and elaboration explanations for the Cl effect
A Taxonomy of Usability Characteristics in Virtual Environments
No full textDespite intense and wide-spread research in both virtual environments (VEs) and usability, the exciting new technology of VEs has not yet been closely coupled with the important characteristic of usability --- a necessary coupling if VEs are to reach their full potential. Although numerous methods exist for usability evaluation of interactive computer applications, these methods have well-known limitations, especially for evaluating VEs. Thus, there is a great need to develop usability evaluation methods and criteria specifically for VEs. Our goal is to increase awareness of the need for usability engineering of VEs and to lay a scientific foundation for developing high-impact methods for usability engineering of VEs.
The first step in our multi-year research plan has been accomplished, yielding a comprehensive multi-dimensional taxonomy of usability characteristics specifically for VEs. This taxonomy was developed by collecting and synthesizing information from literature, conferences, World Wide Web (WWW) searches, investigative research visits to top VE facilities, and interviews of VE researchers and developers.
The taxonomy consists of four main areas of usability issues: Users and User Tasks in VEs, The Virtual Model, VE User Interface Input Mechanisms, and VE User Interface Presentation Components. Each of these issues is progressively disclosed and presented at various levels of detail, including specific usability suggestions and context-driven discussion that include a number of references. The taxonomy is a thorough classification, enumeration, and discussion of usability issues in VEs that can be used by VE researchers and developers for usability assessment or simply design.

Do Accuracy Requirements Change Bimanual and Unimanual Control Strategies?
No full textBimanual coordination and unimanual aiming are two of the most studied areas in motor learning and control research. However, these areas of study have been combined in only a few experiments. By manipulating the location and the size of targets in Lissajous displays, we combined bimanual coordination tasks with Fitts��� aiming tasks to form bimanual aiming in three experiments.
Experiments 1 and 2 were designed primarily to determine the degree to which the accuracy requirement influences the bimanual control processes when the Index of Difficulty (ID) was systematically increased between trials (Experiment 1) and within trials (Experiment 2) and to determine if the control strategies used to perform bimanual aiming are similar to those used in unimanual aiming. The results indicated that, as ID increased, the end-effectors��� motion gradually switched from cyclical to discrete motion for both unimanual and bimanual aiming tasks. However, the transition in control strategy occurred at a lower ID for the bimanual than the unimanual aiming task. In terms of bimanual coordination, increasing the accuracy requirement/ID reduced relative phase bias between the two limbs, whereas the stability of the coupling remained similar across IDs.
Two tasks (A, B) were designed in Experiment 3 to provide performers opportunities to choose between different manual control strategies. Task A was designed so that the participants could complete the task using either unimanual or bimanual control, whereas Task B was designed so that participants could complete the task using simple or less stable bimanual coordination patterns. The purpose was to determine which control strategy the participants would choose to complete the two tasks and determine the degree to which the accuracy requirement influences the control strategy chosen. The results indicated that for both Tasks A and B at the low ID condition (ID = 2) participants preferred to use a 90�� bimanual coordination pattern that is continuous, but may be more difficult from the bimanual coordination standpoint. At the high ID condition (ID = 4), the participants consistently chose to switch between more stable unimanual left and right movements in Task A and to perform a discrete 90�� bimanual coordination pattern in Task B
