English renewed: Visions of English among teachers of 1966

This article examines the way in which curriculum renewal in English teaching in the late 1960s was brought about largely through the democratic process of teacher participation. It describes the role that the newly formed National Association for the Teaching of English (NATE) played in creating the process in conjunction with American colleagues from the National Council of Teachers of English (NCTE) at the 1966 Dartmouth Conference. The author, who participated in this event, describes the values debated at this conference which underpinned reform and which were subsequently tested out and implemented in England by practitioners in schools, supported by NATE local branches. He asks the reader to consider the ways in which this process of reform differs from the ways in which processes of curriculum change are currently structured.     

Filling a curriculum gap in chemistry

In most science courses at secondary level, the teaching methods used are not tailored to present different approaches to meet the individual differences in pupils’ learning styles or motivation. Much in the detailed objectives, and blow‐by‐blow worksheet approach, will appeal to the conscientious pupil but may turn off the more creative and curious pupil.

Mini‐projects (problem solving at the bench) were used as a vehicle to motivate the curious pupils. Correlations of factors such as convergence/divergence, field‐dependence/field‐independence and motivational traits with ‘success’ in mini‐projects are set out in this paper. The evidence indicates that those who do best in practical problem solving of the mini‐project type are the curious, field‐independent and divergent pupils. However, all categories of pupils were stimulated to varying degrees by the projects.

The process of conceptual change in force and motion during computer‐supported physics instruction

The process of students' conceptual change was investigated during a computer‐supported physics unit in a Grade 10 science class. Computer simulation programs were developed to confront students' alternative conceptions in mechanics. A conceptual test was administered as a pre‐, post‐, and delayed posttest to determine students' conceptual change. Students worked collaboratively in pairs on the programs carrying out predict–observe–explain tasks according to worksheets. While the pairs worked on the tasks, their conversational interactions were recorded. A range of other data was collected at various junctures during instruction. At each juncture, the data for each of 12 students were analyzed to provide a conceptual snapshot at that juncture. All the conceptual snapshots together provided a delineation of the students' conceptual development. It was found that many students vacillated between alternative and scientific conceptions from one context to another during instruction, i.e., their conceptual change was context dependent and unstable. The few students who achieved context independent and stable conceptual change appeared to be able to perceive the commonalities and accept the generality of scientific conceptions across contexts. These findings led to a pattern of conceptual change which has implications for instructional practices. The article concludes with consequent implications for classsrooms. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 859–882, 1999     

Interpretations of graphs by university biology students and practicing scientists: Toward a social practice view of scientific representation practices

Using graphs is a key social practice of professional science. As part of a research program that investigates the development of graphing practices from elementary school to professional science activities, this study was designed to investigate similarities and differences in graph‐related interpretations between scientists and college students engaged in collective graph interpretation. Forty‐five students in a second‐year university ecology course and four scientists participated in the study. Guided by domain‐ specific concerns, scientists' graph‐related activities were characterized by a large number of experience‐based, domain‐specific interpretive resources and practices. Students' group based activities were characterized by the lack of linguistic distinctions (between scientific terms) which led to ambiguities in group negotiations; there was also a lack of knowledge about specific organism populations which helped field ecologists construct meaning. Many students learned to provide correct answers to specific graphing questions but did not come to make linguistic distinctions or increase their knowledge of specific populations. In the absence of concerns other than to do well in the course, students did not appear to develop any general interpretive skills for graphs, but learned instead to apply the professor's interpretation. This is problematic because, as we have demonstrated, there are widely differing viable interpretations of the graph. Suggestions for changes in learning environments for graphing that should alleviate this problem are made. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 1020–1043, 1999     

Action Learning: More Than Just A Task Force

Action learning, as it is often implemented in the U.S., differs little from a typical cross-functional task force. Those characteristics of action learning that originated with Reginald Revan's work and that have such potential to change both organizations and participants are often absent in the Americanized version of action learning. Outlined here are the principles that underlie Revan's work as well as an explanation of why they are so critical to both individual development and organizational problem resolution. These principles are then contrasted with a case study of a Fortune 500 company which implemented the more Americanized version. The benefits of that implementation are explored as well as a discussion of the learning difficulties the teams experienced.     

The impact of chronic carbohydrate manipulation on mucosal immunity in elite endurance athletes

Carbohydrate (CHO) availability could alter mucosal immune responses to exercise. This study compared the effect of three dietary approaches to CHO availability on resting and post-exercise s-IgA levels. Elite race walkers (n = 26) adhered to a high CHO diet (HCHO), periodised CHO availability (PCHO) or a low CHO/high fat diet (LCHF) for 3 weeks while completing an intensified training program. HCHO and PCHO groups consumed 8.0–8.5 g.kg^?1 CHO daily, with timing of ingestion manipulated to alter CHO availability around key training sessions. The LCHF diet comprised 80% fat and restricted CHO to < 50 g.day^?1. A race walk test protocol (19 km females, 25 km males) was completed at baseline, after adaptation, and following CHO restoration. On each occasion, saliva samples were obtained pre- and post-exercise to quantify s-IgA levels. Resting s-IgA secretion rate substantially increased ~ two-fold post-intervention in all groups (HCHO: 2.2 ± 2.2, PCHO: 2.8 ± 3.2, LCHF: 1.6 ± 1.6; fold-change± 95% confidence limits), however, no substantial differences between dietary treatments were evident. Post-exercise, substantial 20–130% increases in s-IgA concentration and 43–64% reductions in flow rate occurred in all dietary treatments, with trivial differences evident between groups. It appears that high volume training overrides any effect of manipulating CHO availability on mucosal immunity in elite athletes.     

Associations between prolonged sedentary time and breaks in sedentary time with cardiometabolic risk in 10–14-year-old children: The HAPPY study

This study examines the association between prolonged sedentary time and breaks in sedentary time with cardiometabolic risk in 10–14-year-old children. This cross-sectional design study analysed accelerometry-determined sedentary behaviour and physical activity collected over 7 days from 111 (66 girls) UK schoolchildren. Objective outcome measures included waist circumference, fasting lipids, fasting glucose, blood pressure, and cardiorespiratory fitness. Logistic regression was used for the main data analysis. After adjustment for confounders, the odds of having hypertriglyceridaemia (P = 0.03) and an increased clustered cardiometabolic risk score (P = 0.05) were significantly higher in children who engaged in more prolonged sedentary bouts per day. The number of breaks in sedentary time per day was not associated with any cardiometabolic risk factor, but longer mean duration of daily breaks in sedentary time were associated with a lower odds of having abdominal adiposity (P = 0.04) and elevated diastolic blood pressure (P = 0.01). These associations may be mediated by engagement in light activity. This study provides evidence that avoiding periods of prolonged uninterrupted sedentary time may be important for reducing cardiometabolic disease risk in children.
