Institutional Contexts and International Performances in Schooling: comparing patterns and trends over time in international surveys

15 European countries were classified into four types in an international comparative study. The country profiles are based on indicators of the key concepts' funding, governance and choice. This research attempts to answer the question of how the quality of schooling of these types of education systems progressed as from 1995 and what explanations an expert panel of educationalists and researchers can provide for the outcomes. We observe significant differences between the performance trends of the four types of education systems. Also, comparisons between the different years show relatively high and significant correlations, especially between the original sample of countries in 1995 and future performances in TIMSS and PISA measurements.     

The influence of a 6.5% carbohydrate-electrolyte solution on performance of prolonged intermittent high-intensity running at 30°C

Nine male student games players consumed either flavoured water (0.1 g carbohydrate, Na⁺ 6 mmol · l^?1), a solution containing 6.5% carbohydrate-electrolytes (6.5 g carbohydrate, Na⁺ 21 mmol · l^?1) or a taste placebo (Na⁺ 2 mmol · l^?1) during an intermittent shuttle test performed on three separate occasions at an ambient temperature of 30°C (dry bulb). The test involved five 15-min sets of repeated cycles of walking and variable speed running, each separated by a 4-min rest (part A of the test), followed by 60 s run/60 s rest until exhaustion (part B of the test). The participants drank 6.5 ml · kg^?1 of fluid as a bolus just before exercise and thereafter 4.5 ml · kg^?1 during every exercise set and rest period (19 min). There was a trial order effect. The total distance completed by the participants was greater in trial 3 (8441 ± 873 m) than in trial 1 (6839 ± 512, P < 0.05). This represented a 19% improvement in exercise capacity. However, the trials were performed in a random counterbalanced order and the participants completed 8634 ± 653 m, 7786 ± 741 m and 7099 ± 647 m in the flavoured water (FW), placebo (P) and carbohydrate-electrolyte (CE) trials, respectively (P = 0.08). Sprint performance was not different between the trials but was impaired over time (FW vs P vs CE: set 1, 2.41 ± 0.02 vs 2.39 ± 0.03 vs 2.39 ± 0.03 s; end set, 2.46 ± 0.03 vs 2.47 ± 0.03 vs 2.47 ± 0.02 s; main

effect time, P < 0.01). The rate of rise in rectal temperature was greater in the carbohydrate-electrolyte trial (rise in rectal temperature/duration of trial, °C · h^?1; FW vs CE, P < 0.05; P vs CE, N.S.). Blood glucose concentrations were higher in the carbohydrate-electrolyte than in the other two trials (FW vs P vs CE: rest, 4.4 ± 0.1 vs 4.3 ± 0.1 vs 4.2 ± 0.1 mmol · l^?1; end of exercise, 5.4 ± 0.3 vs 6.4 ± 0.6 vs 7.2 ± 0.5 mmol · l^?1; main effect trial, P < 0.05; main effect time, P < 0.01). Plasma free fatty acid concentrations at the end of exercise were lower in the carbohydrate-electrolyte trial than in the other two trials (FW vs P vs CE: 0.57 ± 0.08 vs 0.53 ± 0.11 vs 0.29 ± 0.04 mmol · l^?1; interaction, P < 0.01). The correlation between the rate of rise in rectal temperature (°C · h^?1) and the distance completed was ?0.91, ?0.92 and ?0.96 in the flavoured water, placebo and carbohydrate-electrolyte conditions, respectively (P < 0.01). Heart rate, blood pressure, plasma ammonia, blood lactate, plasma volume and rate of perceived exertion were not different between the three fluid trials. Although drinking the carbohydrate-electrolyte solution induced greater metabolic changes than the flavoured water and placebo solutions, it is unlikely that in these unacclimated males carbohydrate availability was a limiting factor in the performance of intermittent running in hot environmental conditions.     

PROGRAMS OF STUDY AS A BASIS FOR SELECTION, PLACEMENT AND GUIDANCE OF COLLEGE STUDENTS

Studies of collegiate success and attrition are generally conducted at the all-college level. The definition of academic programs that are homogeneous in the abilities and interests of their students and the grading standards of their faculties may lead to more accurate prediction of success and more effective control of attrition.
Homogeneous curricular groups were defined via Ward's hierarchical grouping analysis applied to curricular means on high school percentile rank, four ACT subscores, first semester GPA, and 16 Kuder scores. Programs so defined differed on scientific-verbal and competitive level dimensions. Prediction of grades was more accurate within programs than colleges. Drop and transfer rates were correlated with discriminant scores.
The programs are discussed as promising units within which differential selection and placement strategies might reduce attrition.     

A Comprehensive Approach to Human Relations Training for Teachers

This article develops a comprehensive approach to human relations training (HRT) for teachers based on knowledge of student diversity and application of communication skills. The author treats HRT as more than just training in communication skills and develops a model that integrates the two major components of HRT. He also develops specific goals, skills, and attitudes capable of being fitted into a teaching paradigm.     

THE INFLUENCE OF TEST TITLE ON TEST RESPONSE

This study was designed to determine the extent to which responses to test items of the type frequently found in personality inventories would be influenced by the title associated with the test. The basic hypothesis was that subjects respond to the test title by developing a particular response set which will be reflected in the individual responses. An instrument was constructed and administered to eight treatment groups. Each administration differed primarily in the title each group's tests bore. The dependent variables were measures of the tendency to lie, respond defensively, answer carefully, and complete questions. Subjects tended to lie and respond more defensively to titled tests than to a test having no title and administered under nonthreatening conditions. All other comparisons were not statistically significant.     

INTERACTIVE EFFECTS OF CREATIVITY AND IQ ON NINTH-GRADE ACHIEVEMENT

The interactive effects of IQ and creativity upon ninth-grade achievement were examined, with special focus upon the IQ threshold concept of Torrance He hypothesized that achievement is predicted better by IQ than by creativity below the IQ threshold, while IQ validity decreases as creativity validity increases above the threshold. This implies an IQ X Creativity interactive effect on achievement. If an IQ threshold exists, regression weights for IQ X Creativity interactive predictors should be statistically significant when included in multiple regression equations. Three creativity factor scores were estimated and were each multiplied by IQ to define three moderated or interactive predictor variables. A slight though statistically significant increase in validity resulted by adding the moderated variables to IQ and the three factor scores in multiple regression equations. Thus, there was weak support for the existence of an IQ threshold, but the regression of achievement on creativity decreased rather than increased with higher IQ.     

Wellbeing and Education: Issues of Culture and Authority

The idea that education should equip people to lead flourishing lives and help others to do so is now becoming salient in policy-making circles. Philosophy of education can help here by clarifying what flourishing consists in. This essay examines one aspect of this. It rejects the view that wellbeing goods are derivable from human nature, as in the theories of Howard Gardner and Edmond Holmes. It locates them, rather, as cultural products, but not culturally-relative ones, drawing attention to the proliferating forms they have taken over the past three or four centuries. It looks to aesthetics and art criticism as a guide to a philosophical treatment of wellbeing goods more generally. It also takes off from aesthetics and art criticism in seeking to identify reliable authorities on the flourishing life. On this, it rejects elitist conceptions in favour of a more democratic model, emphasising its importance in education for citizenship.     

From Constructionism to Deconstructionism: Anticipating Trends in Educational Styles

This paper reviews various issues concerned with the design of computer-based learning (CBL) systems and the educational philosophies from which they are derived. It considers them from the point of view of four themes of contemporary thinking: rational, pragmatic, critical and radical. In particular, the paper considers the current enthusiasm for constructionist learning and teaching methods and how these may evolve in the light of recent research. It is seen that many of the current trends in CBL system design can be related to post-modern ideas about the role of technology in society.
