Skill Evaluation of Majors in Physical Education
Skill tests for majors in physical education are essential to the evaluation of the abilities of the prospective teacher in physical education. Such a testing program would indicate to some extent the effectiveness of the instructional program skills. There appears to be a scarcity of research in skill testing for physical education majors. It was felt by the author that a means of evaluating the skill ability of majors in physical education at South Dakota State was needed in order to determine their level of proficiency and to also give them a better understanding of the values of attaining a prescribed level of skill competency. This study attempted to devise a battery of skill tests for the evaluation of skill ability of majors in physical education at South Dakota State University in selected physical activities. The activities which were included were as follows: golf, tennis, and tumbling. If the author found that no test was available in the area to be evaluated, the construction of a test was required
Teaching Minimum Based Competency Test Skills to Secondary-Aged Learning Disabled Students Through The Use of Precision Teaching
This project investigated whether a precision teaching method used with learning disabled high school students (grades 9-12) could give them the skills needed to pass a minimum based competency test in the area of local, state and national government. The specific objective of this project was to determine if the use of precision teaching enabled the students to retain the facts needed to pass a competency test required for graduation. A multiple-baseline design across behaviors was used to show the effect of precision teaching in mastering the needed facts. The data from each baseline improved and surpassed the set criteria when the intervention was introduced. The Cache School District requires mastery level test score of 70% or higher for each competency test. The pretest scores of the students in this study ranged from 40% to 58%. When all three interventions were completed, the students\u27 test scores ranged from 92% to 100%, thus meeting and surpassing the school district\u27s mastery level
The negative Bogoliubov dispersion in exciton-polariton condensates
Bogoliubov's theory states that self-interaction effects in Bose-Einstein
condensates produce a characteristic linear dispersion at low momenta. One of
the curious features of Bogoliubov's theory is that the new quasiparticles in
the system are linear combinations of creation and destruction operators of the
bosons. In exciton-polariton condensates, this gives the possibility of
directly observing the negative branch of the Bogoliubov dispersion in the
photoluminescence (PL) emission. Here we theoretically examine the PL spectra
of exciton-polariton condensates taking into account of reservoir effects. At
sufficiently high excitation densities, the negative dispersion becomes
visible. We also discuss the possibility for relaxation oscillations to occur
under conditions of strong reservoir coupling. This is found to give a
secondary mechanism for making the negative branch visible
