The development and preliminary assessment of a set of video‐taped informative speech models

Guidelines are specified in this article for developing video‐taped informative speech models. Faculty members rated selected video‐taped informative speeches on nine variables and two months later rated nine of the same speeches again. The faculty judges were reliable on their ratings for eight of the nine variables rated during the two sessions. Five of the nine speeches were identified as being representative of one of three significantly different levels of excellence.     

Variability and Sampling Inspection in the NOCSAE Standards for Football Helmets

Abstract

Because of increasing numbers of serious sports-related injuries at all levels of participation, the National Operating Committee on Standards for Athletic Equipment (NOCSAE) was formed. Among their activities aimed at improving the safety of sports participation was the development of standards for impact resistance in both new and refinished football helmets. These standards include not only recommendations as to safe levels of resistance to impact but recommendations as to the number of helmets to be tested from each group of helmets undergoing a refinishing process.

In this study the various sources of variability in the testing procedure are examined. These sources include helmet-to-helmet variability, testing variability, and basic measurement error. A careful examination of this variability in the context of the NOCSAE-recommended testing procedures for recertifying helmets reveals an inadequacy in the NOCSAE standard, in that the probability of returning unsafe helmets to the playing field is unacceptably high.     

Constructive readings of interactive episodes: examining ethics in physical education from a social constructionist perspective

In this paper we illustrate how ways of thinking about ethics are tied up with sport and physical education practice and introduce an alternative approach that can help to develop ethical pedagogies. We begin by locating socio-moral education in physical education within historical and contemporary pedagogical scholarship. Our argument is that the work of today's physical educators is still shaped by claims that were made about school sport in the nineteenth century and that sport scholars have long had difficulties proving these claims empirically. Rather than search for data that can confirm or refute claims of moral learning, we examine how incidents related to moral behaviour occur during physical education lessons. To do this we draw on data from an ethnographic investigation of a school in North Western Switzerland. Specifically, we present three episodes of interaction in three different physical education lessons. To make sense of these episodes, we introduce a social constructionist perspective. The main assumptions of this perspective are: (1) meanings are created through dialogue and consensus and are context-relative; (2) interactions between people are joint accomplishments; and (3) contexts affect how people interact with one another. Equipped with a constructionist framework, we then inspect the interactive episodes more closely. We include brief discussions of how constructionist understandings might inform ethics pedagogies in the future, suggesting that practitioners should be cautious of universal understandings of ethics, consider pupils as members of communities that are held together by shared practices, provide space for pupils to position themselves differently during lessons and, finally, account for contextual factors when evaluating pupils’ actions.     

A Practical Introduction to Authoring for Computer-Assisted Instruction. Part I—IPS

IPS is a sophisticated courseware authoring tool. This paper presents an overview of the language, its structure and mode of operation. Some illustrative examples of its use are given and the results of some initial investigations of its potential as a tool for computer-assisted instruction in an open-learning environment are briefly described.     

Student ratings and various instructional variables from a within-instructor perspective

The relationship between class size, instructional method, course level, reason for enrollment, and student ratings of instruction was assessed from a within-instructor perspective. Two hundred fifty-four pairs of courses taught by the same instructor were correspondingly identified and subjected to a stepwise multiple regression procedure. Only class size was found to be a significant predictor of ratings once individual differences between instructors were controlled, hence underlining the importance of (1) taking cognizance of the size of the course when using student ratings of instructors as a measure of teaching effectiveness, and (2) controlling for systematic variation due to instructor idiosyncracies in instructional research.     

DEVELOPING CREATIVE PROBLEM SOLVING IN CIVIL ENGINEERING

The development of creative problem solving in a civil engineering degree course since the late 1960s is outlined. It is shown that prior to the Finniston Report, Middlesex Polytechnic had begun to educate civil engineers to meet an ever changing world.

The results of a psychological testing programme confirm that it is possible to increase the creative ability of students during a civil engineering degree course. An attempt is made to predict the performance of students on examinations and current lines of research are indicated.
