A subtraction experiment with six and seven year old children

This paper gives an account of an experiment involving 176 children of 6 and 7 years and their difficulties with subtraction problems. By using two screening questions, four levels of attainment were established and two teaching programmes were then devised to help the children forward to their next level. The results show that it is possible to assess a level of understanding in subtraction quickly and accurately and that, through the teaching programmes, pre-requisite skills needed to establish a sound foundation for subtraction can be taught. The experiment indicates, however, that an attempt to symbolise too soon is a danger to be avoided.     

Efforts to control by children and adults with the type A coronary-prone behavior pattern.

Glass and his colleagues have suggested that the type A coronary-prone behavior pattern, which is characterized by competitiveness, aggressiveness, and impatience, is a response style aimed at maintaining and asserting control over poentially uncontrollable events. The present investigation examined the initial reactions of type A and type B boys and men to uncontrollable events. Children and adults pressed a button to earn nickels on one of the following schedules of reinforcement: a variable ratio of 7 or a fixed ratio of 7. The variable ratio schedule was assumed to appear less controllable than the fixed ratio schedule. The task was either of high or low salience (prominence). Results replicated previous research that type A's initially respond to highly salient uncontrollable events with more vigorous efforts to assert control than type B's. More importantly, the findings provided the first evidence that (1) the initial response to loss of control of type A and type B boys parallels that of their adult counterparts; and (2) the boys' response to the salience of the task is similar to that of their adult counterparts. Implications of the children's responses to uncontrollable events for the maintenance of type A behavior into adulthood and for the etiology of heart disease are discussed.     

On-line professionals

Psychotherapy and counselling services are now available on-line, and expanding rapidly. Yet there appears almost no ethical analysis of this on-line mode of delivery of such professional services. In this paper I present such an analysis by considering the limitations on-line contact imposes on the nature of the professional–client relationship. The analysis proceeds via the contrast between the face-to-face case and the on-line case. At the core of the problem must be the recognition that on-line interaction imposes a physical barrier largely permitting only those disclosures of self we choose to make available, and greatly restricting the range of involuntary features and behaviours. I show why this is problematic, first, for the development of a close professional–client relationship, with particular emphasis on such failures as diagnosis and monitoring of the patient. Second I describe the importance of the development of professional character, and of how the on-line environment fails to provide a context for such character traits to emerge and develop.     

Theorising teaching and learning: pre-service teachers’ theoretical awareness of learning

We examine pre-service teachers’ theoretical learning during one five-week training module, and their educators’ learning about better lecture design to foster student learning. The study is iterative: interventions (one per group) were implemented sequentially in student groups A–C, the results of the previous intervention serving as the baseline for the design developed for the next. These learning study participants, 79 students from year three of a teacher training programme, studied the variation theory (VT) of learning. Three lesson cycles were completed, each comprising four steps: (1) a pre-test, (2) a 15-min intervention discussing VT, (3) a post-test and (4) a delayed post-test conducted eight weeks later. The results indicated learning differences between groups; qualitative analysis identified three categories of student answers, i.e. emergent, premature and unaware, regarding their theoretical understanding. Group C had more students with emergent knowledge (36%) than did groups A (20%) or B (17%) at post-testing.     

Positioning in groups: a new development in systemic consultation

This article describes a new approach, employing a combination of Positioning Theory and Semantic Polarities, that educational psychologists can use to develop and facilitate change in organisations and groups. Resistance to change can be seen as reflecting a lack of the language that the members of an organisation need to participate effectively in the new discourses that are associated with change. Positioning Theory can be used to develop this new language of participation, which can then be used by all in the organisation or group to agree how development can happen and what their contribution to this would be.     

Adolescents’ sleep and adjustment: Reciprocal effects

Reciprocal relations between sleep and adjustment were investigated. Participants included 246 adolescents (M = 15.80 years; 67.5% White, 32.5% Black/African American; 53% female, 47% male) at Time 1 (data collected 2012–2013), 227 at Time 2 (M = 16.78 years) and 215 at Time 3 (M = 17.70 years). Sleep–wake variables were measured with self-reports (sleepiness) and actigraphy (average sleep minutes and efficiency, variability in sleep minutes and efficiency). Adolescents reported on depression and anxiety symptoms, and parents reported on externalizing problems. Greater variability in sleep duration and efficiency as well as sleepiness predicted adjustment problems (range of R²: 36%–60%). Reciprocal relations were supported mostly for sleepiness (range of R²: 16%–32%). Results help understand bidirectional relations between sleep and adjustment.
