Real-time simulation in computer-assisted instruction

Large scale computer-assisted instruction systems generally impose severe constraints upon the demands that individual users may make. Nevertheless, it is possible to overcome these problems and a program is described which teaches students how to fly a specific maneuver through real-time simulation of the flight of a student-controlled airplane. This is achieved in spite of the fact that the student is flying his plane through the use of a manually controlled analog input device. Both computational and educational implications are discussed.Contractual support for this work was provided in part by the Life Sciences Program Air Force Office of Scientific Research, Contract number F44620-70-C-0105.

Toward a Multidimensional Perspective on Teacher-Coach Role Conflict

Research grounded in role theory and occupational socialization theory point to the potential consequences of occupying the roles of physical education teacher and athletic coach concurrently. Specifically, time constraints and inconsistencies in role requirements, organization, rewards, and modes of accountability in teaching and coaching create challenges and may force some teacher/coaches to choose one role as primary to the detriment of the other role. However, most of this research has diminished or altogether neglected the impact of individual identity and social context on the experience of role conflict. The purpose of this paper is to review research related to role conflict in the dual role of teacher/coaches and to propose a conceptual model for viewing teacher/coaches role conflict from a multidimensional perspective. Finally, a case is made for a revitalization of teacher/coaches role conflict research in physical education.     

DEVELOPMENTAL MATHEMATICS: AN EX POST FACTO STUDY

Virginia Western Community College (VWCC) conducted a two‐year follow‐up of its developmental mathematics students. The students left a statistical path that led to some important implications about the efficiency of VWCC's program and that identified some variables and relationships that other developmental educators may want to investigate. Some major findings were: (1) Blacks and males enrolled in and failed developmental mathematics at significantly higher rates than whites and females. (2) Female instructors exhibited significantly higher pass rates than male instructors, and there appeared to be an interaction between the sex of the instructors and the sex of the students. (3) The developmental program effectively prepared its graduates for all of the college level mathematics courses except business mathematics. (4) The pass rates of the developmental teachers varied significantly, but there was no correlation between their pass rates and the college level success rates of their graduates.     

Gender differences in South African men and women's access to and evaluation of informal sources of sexual and reproductive health (SRH) information

While much research has documented unsatisfactory sexual and reproductive health (SRH) awareness among young people in South Africa, understanding of gender differences in access to and evaluation of SRH information is limited. This paper concerned itself with men and women's informal sources and content of SRH, and gendered divergences around accessibility, evaluation, and impact of such information. Fifty sexual history narrative interviews and twenty-five narrative interviews with women were conducted with participants purposively sampled from a range of ages, cultural and racial backgrounds, and in urban and rural sites across five provinces in South Africa. Data were analysed using thematic analysis. While young women were more likely to learn about SRH information from family members, they also reported greater regulation concerning their sexuality. This could enhance stigma surrounding women's sexuality and hinder open communication. Men predominantly learned about sex through pornography and peers, which was reported to encourage sexual prowess to the neglect of practising safer sex. Lack of adequate SRH instruction for young people as revealed through the narratives had significant and often negative implications for men and women's early safer sex behaviours. In response to these insights, recommendations are offered to strengthen informal sources of SRH awareness.     

A critique of neo-Hahnian outdoor education theory. Part one: Challenges to the concept of “character building”

Abstract

Within the diverse and sometimes amorphous outdoor education literature, “neo-Hahnian” (NH) approaches to adventure education are exceptional for their persistence, seeming coherence, and wide acceptance. NH approaches assume that adventure experiences “build character”, or, in modern terminology, “develop persons”, “actualise selves”, or have certain therapeutic effects associated with personal traits. In social psychological terms NH thought is “dispositional”, in that it favours explanations of behaviour in terms of consistent personal traits. In this paper I critically review NH OAE in an historical context, and draw on Ross' and Nisbett's (1991) seminal review of dispositional social psychology to argue that OAE programs do not build character, but may provide situations that elicit certain behaviours. For OAE research and theory, belief in the possibility of “character building” must be seen as a source of bias, not as a foundation. The conceptual analysis I develop provides not only a basis for critique, but also offers a way forward for OAE.     

Exploring transitions into the undergraduate university world using a student-centred framework

ABSTRACT

This paper presents a small-scale qualitative study, which addressed stories of ‘becoming an undergraduate student’. The work took place in one university in the South West of England and involved 4 researchers, 4 co-researchers (undergraduate students) and 12 students from a Faculty of Arts and Humanities. Stories of ‘becoming student’ were perceived and experienced by the researchers as containing complex histories, intertwined with problematic systemic processes, which combined to create challenging, political and diverse realities for students. There was a consensus amongst the researchers that institutional practices did not work to uncover these lived experiences, nor aim to understand them. The study aimed to gain further insight into what becoming a student entails, how ‘student’ is positioned by the academy and to consider how future practices could make transitions into the student world more visible, shared and understood. The work highlights how processes and experiences of becoming an undergraduate student are wide, varied and complex but there are common matters of concern; issues of resources, the importance of student networks and the impact of external perceptions. The authors suggest that if these aspects of the student world were made more visible and understood, Higher Education (H.E) may be better prepared to support positive student transition, success and overall experience.     

Perceived Benefits of Anatomy Coursework Prior to Medical and Dental School

Student struggles in gross anatomy coursework at the professional level can result in hours of remediation along with a need to allot time and other resources by both the student and the faculty. Since this course typically occurs in the first semester of the first year, programs can turn to admissions data to try to determine which of these students may struggle. This study looked at two years of medical (n = 280) and dental (n = 78) students to determine if there is a relationship between pre-admissions anatomy coursework and performance in gross anatomy at the professional school level. Students provided data regarding their past anatomy coursework and final grades in professional school gross anatomy courses were obtained. In addition, students responded to questions regarding their feelings of preparation and how they valued the prior anatomy coursework as it related to the professional course. Statistical analysis showed no difference in final course grade between students with and without prior anatomy in either program. Counter to the numerical data, 96.6% of the students in the study recommended an anatomy course prior to pursuing a health science degree. The primary reasons given for this recommendation were the benefits of repeated content exposure, knowledge of the anatomy terminology, and decreased stress regarding the course. The results from this study suggest that the benefits of prior anatomy may be seen more in the students’ stress and quality of life rather in the numerical performance of course grades.     

Broadening out and opening up technology assessment: Approaches to enhance international development,co-ordination and democratisation

Technology assessment (TA) has a strong history of helping to identify priorities and improve environmental sustainability, cost-effectiveness and wider benefits in the technology policies and innovation strategies of nation-states. At international levels, TA has the potential to enhance the roles of science, technology and innovation towards achieving the Millennium Development Goals, effectively implementing the UN Framework on Climate Change and fostering general global transitions to ‘green economies’. However, when effectively recommending single ostensibly ‘best’ technologies or strategies, TA practices can serve unjustifiably to ‘close down’ debate, failing adequately to address technical uncertainties and social ambiguities, reducing scope for democratic accountability and co-ordination across scales and contexts. This paper investigates ways in which contrasting processes ‘broadening out’ and ‘opening up’ TA can enhance both rigour and democratic accountability in technology policy, as well as facilitating social relevance and international cooperation. These methods allow TA to illuminate options, uncertainties and ambiguities and so inform wider political debates about how the contending questions, values and knowledges of different social interests often favour contrasting innovation pathways. In this way TA can foster both technical robustness and social legitimacy in subsequent policy-making. Drawing on three empirical case studies (at local, national and international levels), the paper discusses detailed cases and methods, where recent TA exercises have contributed to this ‘broadening out’ and ‘opening up’. It ends by exploring wider implications and challenges for national and international technology assessment processes that focus on global sustainable development challenges.     

Discourses on bad children and bad schools

First, discourse is discussed as concerning the subtler lineaments of knowledge production in notions about difference and difficulty. The unhelpful influences that these notions have had on the development of special education research and practice are discussed. The importance of the scholar-practitioner in undoing some of these understandings is further developed. Second, the point is stressed that politics and political questions are intertwined with empirical questions and that a discourse of objectivity propagates and fosters a belief that the supposed paraphernalia of science (measurement, experiment, prediction) can be employed without cost. Third, the point is made that the individual discourse is rooted in the theoretical context of special education--with unhelpful consequences for the way that difficulty continues to be construed as rooted in individuals, whether those individuals be children or schools.
