Look At That! Video Chat and Joint Visual Attention Development Among Babies and Toddlers

Although many relatives use video chat to keep in touch with toddlers, key features of adult–toddler interaction like joint visual attention (JVA) may be compromised in this context. In this study, 25 families with a child between 6 and 24 months were observed using video chat at home with geographically separated grandparents. We define two types of screen‐mediated JVA (across‐ and within‐screen) and report age‐related increases in the babies’ across‐screen JVA initiations, and that family JVA usage was positively related to babies’ overall attention during video calls. Babies today are immersed in a digital world where formative relationships are often mediated by a screen. Implications for both infant social development and developmental research are discussed.     

Hearing Truth from Power? Organisation Theory,School Effectiveness and School Improvement

School effectiveness and school improvement researchers have increasingly looked towards establishing some kind of synergy between their respective fields. However, most recent attempts to create such links have not sufficiently addressed their different perspectives on organisational development and change. School effectiveness research has tended to view organisational development in terms of structural change, while the school improvement field has conversely placed an emphasis upon the cultural dimensions of organisational change. This has resulted in a methodological and theoretical divide that has proved difficult to resolve. This article argues that by incorporating the concept of 'power' into the analysis the two fields can be brought together more successfully. The article suggests that this 'third dimension' provides a bridge between structural and cultural analysis. It also highlights some important research questions that arise out of this tripartite relationship. The article concludes by suggesting that an analysis of power may provide the long awaited conceptual and theoretical fusion sought by both fields.     

International Council for Educational Media Conference Notice 1988

Abstract

The article looks at the production and use of divergent and convergent media and the associated delivery systems. It considers the pros and cons of the systems for various types of learner and concludes that although multimedia is the direction, the choice of multimedia must rest with the analyst.     

Learning Styles and Strategies of Postgraduate Students

Research by Pask has suggested that matching and mismatching teaching strategies with learners'preferred learning strategies may have considerable effects of learning. The study reported here sought to explore the extent to which a group of experienced and successful learners, such as postgraduate students, might be expected to be versatile learners, in the sense of being able to learn equally well from holist and serialist learning materials. Eighty-three postgraduate students completed two questionnaires designed to assess learning styles. Twenty-six students also took two tests designed to assess their competence in learning from materials designed to suit holist and serialist learning strategies. Only two out of 26 students scored equally well on the tests of holist and serialist competence. The study also examines the extent to which holist and serialist competence may be predicted by relatively'quick and easy'questionnaire instruments. In 19 out of 23 cases such competence could be predicted from responses to a number of items from one of the questionnaires. Implications for further research are discussed.     

Do Football Teams Have Clusters of Wins,Draws and Defeats?

The issue of whether football teams have good or bad patches during the course of a season is of concern to many supporters. This interest can be harnessed to make the classroom teaching of probability more relevant. In this article, the unfamiliar runs test for multiple outcomes is used to test for possible clustering in wins, draws and defeats in a short series of consecutive matches.     

Amount of solution drunk is a factor in the establishment of taste aversion

Experiment I demonstrated that the strength of a rat’s aversion to saccharin is a direct function of the amount of saccharin it consumed prior to poisoning. Using Kalat and Rozin’s (1973) procedure, Experiment II showed that results consistent with a “learned-safety” theory of taste aversion appear to depend on whether rats drink most saccharin on their first or second exposure to the solution prior to poisoning. Experiment III demonstrated that when animals drank equal amounts of saccharin solution on each of two exposures prior to poisoning, evidence strongly confirming the “learned-safety” theory was obtained. These experiments together demonstrate the importance of amount of solution drunk in the determination of taste aversion.     

Evaluating a bedside tool for neuroanatomical localization with extended‐matching questions

Neuroanatomical localization (NL) is a key skill in neurology, but learners often have difficulty with it. This study aims to evaluate a concise NL tool (NLT) developed to help teach and learn NL. To evaluate the NLT, an extended‐matching questions (EMQ) test to assess NL was designed and validated. The EMQ was validated with fourth‐year medical students and internal medicine and neurology residents. The NLT's usability was evaluated with third‐ and fourth‐year students, and the effectiveness was evaluated with an experimental study of second‐year students, using the EMQ as the outcome measure. Students were taught how to use both the NLT and textbook algorithms (control) to perform NL, then randomized into either group, and only allowed to use their assigned tool to complete the EMQ. Primary outcome was the difference in mean EMQ scores expressed as a percentage of total score. For EMQ validation, students (n = 56) scored lower than residents (n = 50) (76.7% ± 1.7 vs. 83.0% ± 1.6; mean ± standard error of mean, P < 0.009). The EMQ demonstrated good reliability (Cronbach's α 0.85) and generalizability (G‐coefficient 0.85). Third‐ (n = 77) and fourth‐year (n = 42) students found the NLT user‐friendly and helpful in their learning of NL. In the experimental study, scores were significantly higher for NLT group (n = 94) than for controls (n = 101) (42.5 vs. 37.0%, P = 0.014); the effect size (Cohen's d) was 0.36. The EMQ is validated to reliably assess NL and is generalizable, feasible, practical, and of low cost. The concise and user‐friendly NLT for NL was effective in aiding medical student performance of NL. Anat Sci Educ 11: 262–269. © 2017 American Association of Anatomists.
