'Greyish Rectangles': Creating the television heritage

In the early months of 1947, as it sought to save power during an acute fuel crisis, Clement Attlee's Labour government suspended the publication of all British periodicals for a period of two weeks. This would have been a bold step for any government, let alone one which had as uncomfortable a relationship with the press as Attlee's did, and, at the time, the press was not slow to suggest that the suspension was motivated as much by political factors as it was by a desire to conserve fuel. This article examines the implementation and nature of the suspension, exploring the tensions it generated and asking whether the government's actions can be described—as they were by some contemporary observers—as a deliberate act of suppression.     

Academic and Social Integration in the Basic Communication Course: Predictors of Students' Out-of-Class Communication and Academic Learning

This study reports an investigation designed to determine the generalizability of source credibility scales for immediate superiors across organizational contexts. Four meaningful and statistically independent dimensions for the measurement of the source credibility of immediate superiors in an organizational setting are reported.     

Effects of manipulating relative and absolute motion information during observational learning of an aiming task

In the visual perception perspective of observational learning, the manipulation of relative and absolute motion information in visual demonstrations optimally directs learners’ search towards appropriate task solutions. We assessed the effect of emphasizing transformational information and removal of structural information using point-light kinematic displays in approximating the model’s relative motion patterns. Participants viewed computer-simulated point-light demonstrations or normal video demonstrations before and intermittently throughout 100 acquisition trials with knowledge of results on an underarm modified-dart aiming task. On the next day, all participants performed 20 retention trials without demonstrations. The kinematics of spatial and temporal coordination and control variables were examined relative to the model’s action, as well as performance scores. The results indicated that approximation of the model’s spatial and temporal coordination and control patterns was achieved after observation of either type of demonstrations. No differences were found in movement outcomes. In a second experiment, the effects of manipulating absolute motion information by slowmotion demonstrations were examined relative to real-time demonstrations. Real-time demonstrations led to a closer approximation to the model’s spatial and temporal coordination patterns and better outcome scores, contradicting predictions that slow-motion displays convey intact relative motion information. We speculate that the effect of visual demonstration speed on action perception and reproduction is a function of task constraints ‐ that is, novelty or familiarity of relative motion of demonstrated activities.     

Using Explanatory Item Response Models to Analyze Group Differences in Science Achievement

Correlational evidence suggests that high school GPA is better than admission test scores in predicting first-year college GPA, although test scores have incremental predictive validity. The usefulness of a selection variable in making admission decisions depends in part on its predictive validity, but also on institutions’ selectivity and definition of success. Analyses of data from 192 institutions suggest that high school GPA is more useful than admission test scores in situations involving low selectivity in admissions and minimal to average academic performance in college. In contrast, test scores are more useful than high school GPA in situations involving high selectivity and high academic performance. In nearly all contexts, test scores have incremental usefulness beyond high school GPA. Moreover, high school GPA by test score interactions are important in predicting academic success.     

Social control as a factor in science curriculum change

The contemporary school science curriculum may be regarded as the end‐product of a smooth evolutionary process or as the outcome of a series of decisions made by powerful individuals. The latter view is taken here and an attempt is made to interpret those decisions in terms of the vested interests of the decision makers. Attention is drawn to the need to scrutinize all proposals for science curriculum reform for underlying socio‐political motivation.     

Convergent and Divergent Thinking,Test-Anxiety,and Curiosity

Interrelationships between two motivational variables, test-anxiety and curiosity, and two cognitive variables, convergent and divergent thinking were tested using the measures of convergent and divergent thinking of J. P. Guilford and two self-report true-false scales of test-anxiety and curiosity. Ss were 212 undergraduates, 175 female and thirty-seven male. Based on findings and implications from earlier research, negative relationships of convergent and divergent thinking with test-anxiety, and positive relationships with curiosity were predicted. All correlations for the total group were found to be significant at the .05 level, those with anxiety higher than those with curiosity. Thus, there was support for the view that test-anxiety is negatively related and curiosity positively related to both convergent and divergent thinking. The results were discussed in terms of previous research, and educational implications.     

The end of innocence: critical approaches to Open and Distance Learning

In this article Elin Maher of the University of New Brunswick, Canada, notes that the proliferation of delivery media suggests the need to consider whether and how the medium affects student learning. This paper presents a case study which examines student perceptions of factors affecting learning, and discusses differences in perceptions between classes taught using two different delivery media.     

Responding to expressed needs

In this article, John Cowan (Open University in Scotland), Carlos Alonzo‐Blanqueto (University of Merida, Yucatan) and Derek Fordyce (Heriot‐Watt University) describe their efforts to offer learners genuine openness as regards course content. They draw on three examples from diverse situations to illustrate their use of the ‘sideline tutor’, an arrangement by which learners can directly influence the choice of what they are about to learn and what the teacher teaches’.
