Extending the Discourse on Developmental Appropriateness: A Developmental Perspective

This article makes the argument that the present discourse on developmental appropriateness needs to be expanded. Four points are made: First, the present discourse assumes a consensus about child development that is more apparent than real; second, it is premised on a suspect notion of broad, universal stages; third, it ignores an important alternative perspective to the dominant individualist perspective on learning and development; and fourth, it ignores an important alternative perspective to the dominant view of the relationship between learning and development. Critiques are made and alternative perspectives presented.     

Student performance in off-campus programs

The quality of degree programs offered off-campus, particularly on military bases, has become an issue affecting many institutions of higher education. This study asked the question: Do students in off-campus programs perform as well as students in on-campus programs? As a basis for comparison, only courses taught on- and off-campus by the same instructor were chosen. Six courses, taught 37 times, by ten instructors, met these criteria. The subjects included the 649 undergraduate students from Southern Illinois University-Carbondale who received letter grades in these courses between 1975 and 1977. As a measure of performance, the grades of on- and off-campus students were compared by means of at-test. The mean grade of off-campus students (3.34) was not significantly different (at the .01 level) from that of on-campus students (3.29). As a control, faculty were interviewed to determine the equivalence in content and rigor of courses they taught in both settings. Faculty generally responded that their on- and off-campus courses were equivalent in content and rigor, supporting the use of grades as a measure of student performance. These results indicate that not only do faculty maintain their standards while teaching off-campus, but that the academic performance of off-campus students equals that of on-campus students.     

What can evidence-use in practice learn from evidence-use in policy?

Abstract

Background: This paper approaches evidence-informed practice from the perspective of evidence-informed policy-making. Using the findings of a recent study of evidence-use by educational policy-makers to raise questions about evidence-use by educational practitioners, it seeks to explore what such a study might tell us about how to understand and improve evidence-use by educational practitioners.

Purpose: The paper aims, therefore, to identify potential connections, shared insights and common issues between evidence-use in policy and evidence-use in practice. It does this by focusing on two specific areas: the nature of the evidence (i.e. what evidence is used) and the nature of the use (i.e. how evidence is used). The paper outlines what was found about each of these aspects of evidence-use in policy, and then considers what questions and issues these findings might raise for evidence-use in educational practice.

Sample: The empirical study on which this paper is based was an in-depth study of the use of evidence within educational policy development in Australia. It focused on the development of three specific education policies within one Australian state education department and involved interviews with 25 policy-makers who were actively involved in the development of these policies.

Design and methods: The policy-based study involved the following data collection processes: (i) in-depth semi-structured interviews with 25 policy-makers who were involved in the development of the selected policies; (ii) documentary analysis of policy documents, background research reports and other relevant papers relating to the selected policies; (iii) unstructured observation (where possible) of meetings and events connected with the development of the selected policies; and (iv) feedback from 40 wider policy staff who took part in a verification workshop to discuss the project’s emerging findings.

Findings: Drawing on the findings from the original policy study, two areas of potential connection to evidence-use in practice are explored. First, in relation to ‘varieties of evidence and uses’, the negotiation of diverse evidence types and the potential for using evidence in multiple and varied ways appear to be features of evidence-use that are common to educational policy-makers as well as educational practitioners. Secondly, in relation to ‘narrowness of evidence sources’, there is potential for both policy-makers and practitioners to use a narrow (rather than broad) selection of evidence, due to a tendency to work with certain evidence types as a starting point (e.g. performance data) and a tendency to draw on certain evidence sources more frequently (e.g. well-known, familiar research sources).

Conclusions: This paper emphasises: (i) the need for more integrated (or joined-up) understandings of evidence-use across contexts of practice and contexts of policy; (ii) the importance of continued efforts to understand and represent evidence-use more effectively within educational practices; and (iii) the value of paying careful attention to the quality and qualities of evidence-use within and across the different settings of educational practice and policy.     

The Web and the Unassailable Voice

In most existing art museum Web pages, the values of the museum dominate the values of the Web. Therefore, museum Web pages often electronically duplicate familiar museum products – floor plans, collection catalogues, event calendars – rather than transforming the idea of the museum by adapting the values of the Web.This paper will seek to show how art museums and technologists can come to understand each other and use their differences productively by:1. Orienting museum Web sites towards projects that can only be done on the Web and not on paper.2. Using the Web to overcome the many limitations to understanding imposed by the physical art museum.3. Using the interactive potentials of the Web to change the one-way flow of information from art museum to visitor to a two-way flow which also moves from visitor to museum.4. Infusing the orientation towards constant change into the art museum so that the Web helps the art museum to reinvent itself.     

The effects of carbohydrate supplementation on immune responses to a soccer-specific exercise protocol

The aim of this study was to determine the effect of carbohydrate (CHO) versus placebo (PLA) beverage consumption on the immune and plasma cortisol responses to a soccer-specific exercise protocol in 8 university team soccer players. In a randomized, counterbalanced design, the players received carbohydrate or placebo beverages before, during and after two 90 min soccer-specific exercise bouts (3 days apart) designed to mimic the activities performed and the distance covered in a typical soccer match. Blood and saliva samples were collected before, during and after the exercise protocol. Plasma lactate concentration increased to approximately 4 mmol x l(-1) at 45 and 90 min of exercise in both treatments (P<0.01). Plasma glucose concentration was significantly lower after 90 min of exercise with ingestion of the placebo than the carbohydrate (PLA: 4.57+/-0.12 mmol x l(-1); CHO: 5.49+/-0.11 mmol x l(-1); P<0.01). The pattern of change in plasma cortisol, circulating lymphocyte count and saliva immunoglobulin A secretion did not differ between the carbohydrate and placebo trials. Blood neutrophil counts were 14% higher 1 h after the placebo trial than the carbohydrate trial (PLA: 4.8+/-0.5x10(9) cells x l(-1); CHO: 4.2+/-0.5x10(9) cells x l(-1); P = 0.06), but the treatment had no effect on the degranulation response of blood neutrophils stimulated by bacterial lipopolysaccharide. We conclude that, although previous studies have shown that carbohydrate feeding is effective in attenuating immune responses to prolonged continuous strenuous exercise, the same cannot be said for a soccer-specific intermittent exercise protocol. When overall exercise intensity is moderate, and changes in plasma glucose, cortisol and immune variables are relatively small, it would appear that carbohydrate ingestion has only a minimal influence on the immune response to exercise.     

The effect of ball-carrying technique and experience on sprinting in rugby union

There are several ways of carrying the ball in rugby union, which could influence the speed at which a player can run. We assessed 52 rugby players (34 males, 18 females) during a maximum sprint over 30 m without the ball, with the ball under one arm, and with the ball in both hands. Timing gates were used to measure time over the initial 10 m and the last 20 m. It has previously been reported (Grant et al., 2003) that running with the ball produces a slower sprinting speed than running without the ball. We hypothesized that the decrease in speed caused by carrying the ball would become less marked with the experience of the player. The male and female players were each divided into two groups: a "beginner" group that consisted of players in their first or second season and an "experienced" group that was composed of players who had played for more than two seasons. A 2 x 3 mixed-model analysis of variance was used to identify differences (P < 0.01) between the beginner and experienced groups in the three sprinting conditions. The times for the males for the first 10 m sprints without the ball, with the ball under one arm, and with the ball in both hands were 1.87 +/- 0.08 s, 1.87 +/- 0.08 s, and 1.91 +/- 0.1 s for the beginners, and 1.87 +/- 0.1, 1.88 +/- 0.1 and 1.88 +/- 0.12 for the more experienced players respectively. The times for the females for the first 10 m without the ball, with the ball under one arm, and with the ball in both hands were 2.13 +/- 0.16 s, 2.19 +/- 0.17 s, and 2.20 +/- 0.16 s for the beginners, and 2.03 +/- 0.12 s, 2.03 +/- 0.09 s, and 2.04 +/- 0.1 s for the more experienced players respectively. For the last 20 m of the 30-m sprint, there were differences between the different sprint conditions (P < 0.001) but no differences that were attributable to experience (P = 0.297). The times for the males over the last 20 m without the ball, with the ball under one arm, and with the ball in both hands were 2.58 +/- 0.19 s, 2.61 +/- 0.12 s, and 2.65 +/- 0.12 s for the beginners, and 2.59 +/- 0.12, 2.62 +/- 0.23, and 2.65 +/- 0.18 s for the more experienced players respectively. The times for the females over the last 20 m without the ball, with the ball under one arm, and with the ball in both hands were 3.25 +/- 0.38 s, 3.35 +/- 0.42 s, and 3.40 +/- 0.46 s for the beginners, and 3.04 +/- 0.32 s, 3.06 +/- 0.22 s, and 3.13 +/- 0.27 s for the more experienced players respectively. No gender-specific differences were detected. The results of this study suggest that practising sprints while carrying a ball benefits the early phase of sprinting while carrying the ball.     

Stressed and Losing Sleep: Sleep Duration and Perceived Stress Among Affluent Adolescent Females

This study examined the relationship between stress and sleep duration for adolescent females from affluent backgrounds. Participants were 218 students attending two independent single-sex secondary schools. Ordinary Least Squares (OLS) regression models (cross-sectional and longitudinal) were run to examine the association between stress and sleep duration and to determine whether any associations lasted from the beginning to the end of the academic year. In the cross-sectional models, the relationship between perceived stress and sleep duration was reciprocal and negative. Findings from the longitudinal analyses suggested that perceived stress had lingering negative effects on sleep. Implications for future research and practice are discussed.
