Summation of responding to CSs and an excitatory test context

The influence of test-trial delay of CS onset in obtaining response summation of an excitatory CS and an independently conditioned context was investigated. Water-deprived rats were given tone-shock and click-shock pairings in the training context and unsignaled footshocks in the test context. Durations of lick suppression in response to the tone (Test 1) and the click (Test 2) were then assessed in the test context. Licking was more suppressed when CS onset occurred early in the test session (e.g., 0 sec) than when it occurred later in the test session (e.g., 300 sec). The results from control groups that had received shock in an irrelevant context rather than the test context indicated that this effect was due to fear of the test context rather than diffuse, nonassociative fear. With onset of the clicks early in the test session on the second test day, response summation of the test context with the clicks was observed. This suggests that appreciable spontaneous recovery had occurred from any test-context extinction that took place on the first test day. We conclude that early onset of the CS on the test trial favors response summation of CSs and test context.     

Progression Towards Functions: Students’ Performance on Three Tasks About Variables from Grades 7 to 12

Identifying and expressing relations between quantities is a key aspect of understanding and using functions. We are aiming to understand the development of functions understanding throughout school years in Israel. A survey instrument was developed with teachers and given to 20 high and average achieving students from each of years 7–11 and to 10 high achieving students from year 12, a total of 110 students. Our analytical approach is to identify qualitatively what students appeared to do and whether their approaches led to complete solutions. We look for progress in understanding variables and relations between them, and we found that there does not appear to be a strong link between curriculum and informal understandings of variables and covariation, but there are other strengths.     

Developing educational goals: insights from a Peer Assisted Teaching Scheme

The rapid changes facing higher education are placing increased focus on the quality of the student experience, achieving learning outcomes, and employability expectations. As a result, academics in teaching roles are increasingly measured on performance via student evaluations amplifying attention on professional development initiatives for academics. One such initiative is the Peer Assisted Teaching Scheme currently in practice across many Australian universities. The critical component of the scheme is the establishment of teaching goals that provide focus and direction for the peer partnership. This study addresses two questions: (1) Around which aspects do academics set their goals for teaching improvement? and (2) How do academics’ goals align with the SMART goal-setting framework that is prescribed in the scheme? Findings from five Australian universities showed that goals align with a variety of educational areas yet many were underdeveloped, or misaligned with the proposed strategy. The implications of this are discussed and a framework for setting education goals for teaching improvement is developed.     

A Study of Teacher Assessment at Key Stage 1

This paper is based on semi‐structured interviews with 59 Year 2 teachers across 45 schools in one LEA. It documents their practice of and attitudes to teacher assessment and it proposes a developmental model which describes and explains their approaches. The assessment of process skills is analysed and the effects of assessment on children's learning and teachers’ practice are discussed. The manageability of teacher assessment is also examined. The findings are linked with previous and subsequent studies on teacher assessment and suggestions for further research, based on these outcomes, are offered.     

What the kids will like

For the British teacher interested in children and books, the year's best buy has been a monthly review sheet produced by two Sheffield teachers; 60p for twelve issues, post paid, promptly delivered. CLE invited Jane Powell and Steve Bowles to describe their project; and we publish extracts to illustrate the practical nature of their reviews.     

Contribution of conditioned opioid analgesia to the shock-induced associative US-preexposure deficit

The modulatory effect of conditioned opioid analgesia on learning in the US-preexposure paradigm was examined in three experiments using water-deprived rats. In Experiment 1, it was found that tailflick latencies increased immediately after the rats were exposed to a context in which footshock had previously been administered. Prolonged nonreinforced exposure to the context attenuated this analgesia. Experiment 2 tested the possibility that the effectiveness of CS-US pairings in an excitatory context might be reduced by a conditioned analgesic response that lessens the perceived intensity of the US. Administration of the opiate antagonist naloxone prior to CS-US pairings in the excitatory context reduced the US-preexposure deficit—that is, the retarded response to the CS—but did not eliminate it, suggesting that part of the observed deficit resulted from conditioned activation of the endogenous opioid system. In Experiment 3, it was found that exposure to the excitatory context immediately prior to a CS-US pairing in an associatively neutral context resulted in a conditioned response deficit, indicating that the analgesia elicited by the excitatory context was sufficient to reduce US effectiveness. In combination with other recent reports, these results suggest that the associative deficit resulting from preexposure to a shock US may, in certain instances, represent the sum of several different associative processes.     

Transforming the school workforce: perspectives on school reform in England

This paper describes the experience of change management observed as part of an evaluation of the Transforming School Workforce Pathfinder Project commissioned by the UK Government for the English education system. The 32 Pilot Schools made interventions in organisational practice in ways that required them to think differently about work. Changes in the number, type and deployment of the school workforce combined with thinking about the nature of work have challenged existing practices. In particular, a focus on change management teams drawn from the whole school workforce, supported by an external school workforce advisor, has required schools to examine the nature of decision-making and participation. We intend to draw on evidence from eight case study schools and through this examine the implications for how change is understood and practiced. We critically engage with the government’s preference for a particular model of change to bring about organisational improvement, and we reveal a pluralistic and dynamic field both within practice and theorising.

The association between maltreatment and obesity among preschool children

OBJECTIVE: To determine whether child maltreatment is associated with obesity in preschool children. METHODS: Data were obtained from the Fragile Families and Child Wellbeing Study, a birth cohort study of 4898 children born between 1998 and 2000 in 20 large US cities. At 3 years of age, 2412 of these children had their height and weight measured, and mothers answered items on the Parent-Child Conflict Tactics Scales about three types of child maltreatment--neglect, corporal punishment, and psychological aggression. The frequency of each type of maltreatment behavior in the prior year was analyzed using categories--ever/never for neglect and quintiles for the other two types of maltreatment. Child obesity was defined as measured body mass index (kg/m(2)) > or =95th percentile. RESULTS: Eighteen percent of the children were obese, and the prevalence of any episode of neglect, corporal punishment, and psychological aggression was 11%, 84%, and 93%, respectively. The odds of obesity were increased in children who had experienced neglect (odds ratio 1.56, 95% confidence interval, 1.14-2.14), after controlling for the income and number of children in the household, the mothers' race/ethnicity, education, marital status, body mass index, prenatal smoking, and age, and the children's sex and birth weight. Neither the frequency of corporal punishment nor psychological aggression was associated with an increased risk of obesity. CONCLUSIONS: In a sample of preschool children from 20 large US cities, maternal self-report of neglectful behavior was associated with an increased risk of childhood obesity, after controlling for birth weight, maternal obesity, and multiple socioeconomic factors.
