Undergraduates' personal and social problems and their appropriateness for discussion with a counsellor in a Nigerian university

An instrument, Student Survey Questionnaire, assessed the appropriateness of students' social and personal problems for discussion with a counsellor. It was hypothesized that there would be no significant relationship between the social and personal problems of students and the appropriateness of the problems for discussion with a counsellor. It was tested using a 2×5 chi square contingency table of non-admission or admission of problems against five appropriateness levels. The result showed a significant relationship: the more problems the students admit the more they want to discuss them. Most of the students who admitted they have personal and social problems saw these problems as appropriate for discussion with a counsellor.     

A review of tennis racket performance parameters

The application of advanced engineering to tennis racket design has influenced the nature of the sport. As a result, the International Tennis Federation has established rules to limit performance, with the aim of protecting the nature of the game. This paper illustrates how changes to the racket affect the player-racket system. The review integrates engineering and biomechanical issues related to tennis racket performance, covering the biomechanical characteristics of tennis strokes, tennis racket performance, the effect of racket parameters on ball rebound and biomechanical interactions. Racket properties influence the rebound of the ball. Ball rebound speed increases with frame stiffness and as string tension decreases. Reducing inter-string contacting forces increases rebound topspin. Historical trends and predictive modelling indicate swingweights of around 0.030–0.035 kg/m² are best for high ball speed and accuracy. To fully understand the effect of their design changes, engineers should use impact conditions in their experiments, or models, which reflect those of actual tennis strokes. Sports engineers, therefore, benefit from working closely with biomechanists to ensure realistic impact conditions.     

Students’ communicative behavior adaptability in CSCL environments

By the proliferation of online courses, the social dimension of computer supported collaborative learning (CSCL) is becoming more important than before. Research shows that communicative behavior adaptation to the computer medium is a critical issue in CSCL social relationship development. Two dominant theories in the CSCL field, social information processing theory and adaptive structuration theory, argue that individuals do not simply receive the technology passively but they adapt their behavior to increase benefits from the technology. This paper develops an instrument in order to operationalize the notion of individual’s communicative behavior adaptability in CSCL. Through an exploratory factor analysis performed on a small sample of post graduate students of an online degree in an Australian university, three factors have been unveiled: (1) individual perception of self-representation, (2) individual perception of compatibility, and (3) individual perception of the use of computer technology. Identification of these factors is expected to facilitate understanding of individuals’ social behaviors in CSCL environment, which in turn will guide the design of CSCL systems. In addition, the paper examines the relationships between the extracted factors and four environmental factors: learner’s characteristics, course characteristics, instructor characteristics, and technology characteristics. The results show that none of these characteristics strongly affect perception of self-representation or perception of the use of computer technology. On the other hand, a strong relationship was found between perception of compatibility and learner’s and course characteristics. The reliability as well as validity of the study is examined and findings are discussed. These findings will provide further insights into the design process of CSCL systems.

Winning the Battle,Losing the War: Bilingual Teachers and Post-Proposition 227

The implementation of Proposition 227 has created chaos, uncertainty, and a hostile environment for bilingual education teachers. This study describes the experiences of 20 bilingual education teachers in Southern California. In in-depth interviews, teachers speak out about the challenges, frustrations, fears, and the increasing animosity they face on a daily basis, and how they resist and contest the language enforcer role in various ways. Out of the chaos that has been created by Proposition 227, these bilingual teachers have emerged as the language civil rights activists of the new millennium.     

EXPERIMENTAL RESEARCH IN TELEVISION PRODUCTION TECHNIQUES AND PRESENTATION STRATEGIES: CURRENT DIRECTIONS

This paper, first delivered at the 1979 Conference, reviews 25 years of experimental research into production and presentation variables. A number of suggestions are made for continuing research in specific areas and a bibliography of 45 references is appended.
