Unkindest Cuts? Some effects of picture editing on recall of television news information

Research into picture effects on encoding of verbal material has paid little attention to the effects of picture changes. In this experiment, it was found that adults’ recall of the spoken text in a TV news item was impaired by mid‐sentence picture editing. In contrast, both 11‐12 year old and 14‐15 year old children's recall was enhanced by rapid cutting, so long as the accompanying pictures were relevant to the verbal text. Both adults’ and younger children's recall was better with some of the experimentally‐manipulated material than it was with the original broadcast version of the news item. However, 14‐15 year olds performed best with the original version.

It is suggested that viewers are differentially sensitive to unintended production effects and that their processing of verbal information can be disrupted by inappropriately‐timed picture cuts. Research on picture‐text relationships in audio‐visual material needs to take account of picture‐timing, as well as picture content, and television editing procedures may need to be tailored more specifically to suit the intended audience.     

Images in mirrors: Recollections,alternative explanations and modes of cognitive functioning

Students' conceptions of how objects are seen directly, and in mirrors, were explored in an analysis of their written and drawn responses to common visual phenomena depicted in cartoons with brief text. Students in Grades K-10 (n=214) completed a questionnaire and some were interviewed. Evidence was sought to support an hypothesis for increasingly sophisticated responses related to the concepts of sight, light, reflection and image. The developmental model used in this analysis was the updated SOLO Taxonomy (Biggs & Collis, 1991; Collis & Biggs 1991). It appears from the results that different modes of functioning can interfere to produce factually incorrect recollections of experience particularly in the age group 7 to 13 years approximately. Also, this is associated with the common spurious conception that mirrors have a lateral inversion property. Explanations involving light were extremely rare and its role related to the production of an image ‘in the mirror’ but not to the perception of an image in the eyes.

Learning productivity: a case analysis of the 'e-BOSNO' course for manager teams

Action learning in a workplace context, focused on projects relating to real business needs, is the basis of the management seminars offered by the BOSNO (in Dutch, ‘BedrijfsOpleiding voor Samenwerkende Nederlandse Ondernemingen’[Company training for Dutch companies working in cooperation with each other]) consortium in The Netherlands. In the seminars, managers from participating companies work in teams on multiple‐step problem analysis and solution strategies, supported by workplace coaches. The teams also interact with each other so that peer learning is stimulated. To extend the BOSNO management seminar model in both depth and flexibility, a new approach called e‐BOSNO was designed in which a web‐based learning support environment played a critical role. This paper describes the e‐BOSNO design process and gives results from the first cycle of e‐BOSNO. The results showed the participants to be much more active and interactive than in previous e‐BOSNO seminars, even though there were fewer face‐to‐face meetings. Workplace‐oriented learning occurred and was shared in a way which makes it available for reuse in subsequent e‐BOSNO seminars.     

Document clustering using nonnegative matrix factorization

A methodology for automatically identifying and clustering semantic features or topics in a heterogeneous text collection is presented. Textual data is encoded using a low rank nonnegative matrix factorization algorithm to retain natural data nonnegativity, thereby eliminating the need to use subtractive basis vector and encoding calculations present in other techniques such as principal component analysis for semantic feature abstraction. Existing techniques for nonnegative matrix factorization are reviewed and a new hybrid technique for nonnegative matrix factorization is proposed. Performance evaluations of the proposed method are conducted on a few benchmark text collections used in standard topic detection studies.     

A social constructivist assessment process model: how the research literature shows us this could be best practice

Although assessment is acknowledged as vitally important in its effect on students’ approaches to learning, there is much criticism of assessment practice. This paper argues that if a social constructivist approach is applied to the assessment process many of the problems could be overcome. It describes what a social constructivist approach to assessment would look like and gives practical examples, from the research literature, of ways it could be implemented.     

Visual processing during mathematical problem solving

This study investigated, in the context of mathematical problem solving by secondary school students, the nature of the visual schemata which Johnson (1987) hypothesises mediate between logical propositional structures and rich specific visual images. Four groups of grade 10 students were studied, representing all combinations of high and low operational ability in mathematics (equivalent to Johnson's logical propositional structures) and high and low vividness of visual imagery (corresponding to Johnson's rich images). The results suggested first, that success at problem solving was related to logical operational ability, but not to vividness of visual imagery. Second, a variety of visually based strategies were used during problem solving which differed in their level of generality and abstraction, and use of these strategies appeared related to either logical operational ability or vividness of visual imagery, depending on their level of abstraction. The results supported Presmeg's (1992b) continuum of abstraction of image schemata.Throughout the paper, the first High or Low denotes logical operational ability, and the second, vividness of visual imagery.     

A scholarly approach to solving the feedback dilemma in practice

It is clear from the literature that feedback is potentially the most powerful and potent part of the assessment cycle when it comes to improving further student learning. However, for some time, there has been a growing amount of research evidence that much feedback practice does not fulfil this potential to influence future student learning because it fails in a host of different ways. This dilemma of the disjuncture between theory and practice has been increasingly highlighted by the UK National Student Survey results. This paper uses a model of the assessment process cycle to frame understandings drawn from the literature, and argues that the problem with much current practice resides largely in a failure to effectively engage students with feedback. The paper goes on to explore how best to effectively engage students with assessment feedback, with evidenced examples of feedback strategies that have successfully overcome this problem.     

Reducing Bullying: Application of Social Cognitive Theory

Social cognitive theory (SCT) is an important heuristic for understanding the complexity of bullying behaviors and the social nature of involvement in bullying. Bullying has been heralded as a social relationship problem, and the interplay between the individual and his or her social environment supports this conceptualization. SCT has been used to help guide the development of an individualized intervention for bully perpetrators, which will be described in this article. Intervening directly with those who bully others helps understand individual variation in bullying, as well as teaches bully perpetrators alternative, prosocial ways of interacting with others. Students who bully others exhibit a complex array of psychological, cognitive, and social characteristics. In this article, we argue that to truly reduce bullying, interventions must address these psychological, cognitive, and social contributing factors. Only when interventions target these constructs will individuals be able to transform their bullying behaviors into prosocial interactions.
