A new approach to an old problem

Applying theories of cognition and affect that predict emotional responses to a stimulus on the basis of prior affect toward specific cues included in that stimulus, a study was conducted assessing individuals' fear and enjoyment reactions to horror films. Prior fear of specific cues included in each film was a significant predictor of overall fear reactions, after controlling for prior exposure to the film, fear of specific cues not included in the film, and manifest anxiety. Prior liking of specific cues included in each film did not emerge as a significant predictor of overall enjoyment. The contributions of gender and of level of forewarning about the film's content were also assessed.     

The hypothesis testing knowledge blend

The creation of several forms of knowledge that would enable organizations to ask and say the right things during complex diagnoses is proposed. Based on the concept of knowledge combustion, the hypothesis testing knowledge blend (HTKB) is the cognitive equivalent of petrol for the combustion engine. The HTKB requires the creation of a knowledge hybrid that uses existing technologies to ask and say the right things. In addition to timing mechanisms and problem space maps, two forms of declarative knowledge (directions and explanations) are integrated to create the HTKB. These directions and explanations would be obtained directly from the video recordings of diagnosticians conducting teleconsultations. By providing these profound dialogues during the conduct of complex diagnoses, the HTKB should increase the knowledge capital of organizations. Formal analyses are beginning to validate the conceptual structure (blue print) presented in this paper, and the results will be provided in the future.     

Training skilful teachers

The Teacher Education Project was a research and development project, funded by the Department of Education and Science, which analyzed over 1000 lessons given by novice and experienced teachers in secondary schools. There were 23 research studies which focused principally on class management and control, questioning and explaining, and the teaching of mixed-ability groups. In the case studies of student teachers, effective class managers were seen to have good personal relationships with their students, be well prepared and organized and be able to ask questions skilfully and explain clearly. Most disorder in students' lessons consisted of excessive noise and there were few serious disruptions. Teachers were asked to keep a log of questions they asked and a number of strategies were elicited from their self-reports. Experimental work on explaining showed that the most successful explainers made more varied cognitive demands on pupils, used more framing and focusing statements, and more visual aids. The project produced sets of workbooks which were rated “helpful” or “very helpful” by 90% of users, as well as sets of slides on class management and group work.     

The influence of activity-based elementary science programs on classroom practices: A quantitative synthesis

The results of 11 studies of classroom practices used with the activity-based elementary science programs, ESS, SCIS, and SAPA, were combined quantitatively. All studies included control groups and employed techniques for coding lesson events. A composite category system was developed for combining study results. It was found that teachers using activity-based programs spent about 10% more time on student activity and 10% less time on talk than teachers using traditional methods. More direction giving, more higher level questions, and less lecturing were also reported. Teachers trained in program use spent less time giving directions, more time on activities, and less time on talk than untrained teachers using the programs. On the average, researchers coded slightly less student talk and slightly less student-initiated talk in activity-based classrooms.     

A new approach to assessing the technological complexity of different categories of R&D (with examples from Singapore)

This paper attempts to develop a set of generic questions the answers to which allow any given R&D activity to be correctly classified in one or another conventional R&D box—basic, applied, development, etc. Such systematic pigeon-holing allows latecomer countries to gauge the distance of their R&D activity from the world frontier, and how policies may be designed to overcome the hurdle that divides applied research and developmental research.     

Toddlers’ Self-Recognition and Progression From Goal- to Emotion-Based Helping: A Longitudinal Study

Research has typically used cross-sectional designs to draw conclusions on the development of helping. This study aimed to examine the development of instrumental and empathic helping behaviors as they emerge, and assess how self-recognition might moderate this progression. Seventy-two children (14- to 25-months at T1) were assessed over four monthly sessions. Participants’ individual response patterns showed instrumental helping to be a necessary precursor to empathic helping for 55.77%–67.92% of children who helped during the study. Self-recognition emerged before empathic but not instrumental helping, yet did not directly influence helping behavior.
