Dynamics of the frame in visual composition

The position of an object within a visual composition produces an effect on the observer. Does an observer see the object as strong and active if it is in the center of the picture, in one corner, “floating” off-center? Does the framing of the object or the field surrounding it give an object more meaning? Forty-four college students rated six framed, black-andwhite, single-object pictures. The 264 observations were subjected to principal axis factoring, resulting in four dimensions: activity, potency, evaluative, and verticality.     

Equity in access? The number of the books available in grade 1, 3 and 5 classroom libraries

Learning Environments Research - In this study, we examined students’ access to text, defined as the number of texts freely available to children in their classrooms. From 60 elementary...     

The effect of nonreinforced stimulus exposure on the strength of a conditioned taste aversion as a function of retention interval: Do latent inhibition and extinction involve a shared process?

Two experiments examined the effects of nonreinforced flavor exposure on the strength of a conditioned taste aversion. Rats were conditioned by pairing maple flavor with LiC1. Prior to or subsequent to this pairing, some animals received nonreinforced exposure to either maple or saccharin. In separate subjects, preference for maple was tested 1 or 21 days after the last training episode. In the first experiment, the nonreinforced stimulus exposure occurred before conditioning (latent inhibition, or LI, procedure); in the second experiment, the nonreinforced exposure occurred after conditioning (extinction, or EXT, training). In both experiments, nonreinforced exposure to maple or saccharin reduced the magnitude of a conditioned maple aversion when testing occurred soon after conditioning. When testing was delayed, however, the attenuation due to nonreinforced saccharin exposure dissipated, both with the LI procedure and with EXT. In contrast, the nonreinforced exposure to maple was found to attenuate conditioned reactions at both short and long retention intervals. The release from generalized LI and spontaneous recovery following generalized EXT training are discussed in terms of retrieval processing. The possibility that the same mechanism may underlie LI and EXT is considered.     

Preschool Teacher Uses of Video Technologies

This project was undertaken for the purpose of identifying media design and presentation features that facilitate the acceptance and use of video materials by preschool teachers who teach children with special needs. Information about teachers' awareness of, their preferences for and their uses of video materials and equipment was gathered from interviews, questionnaires and classroom observations. Teachers previewed a sampling of Sesame Street video segments and indicated the segments they thought were useful. The following design features figured prominently in the teachers' selections: segment length, production format, musical lyrics, curriculum relevance, content emphasis, interactivity, perceived interest to children, meaningfulness and simplicity of explanations. The results of a prototype videodisc tryout indicate that the teachers had no difficulty integrating video segments into their teaching routines.     

The Consequences of Teacher Praise and Criticism

A ‘visiting teacher’ gave her lesson, then asked children for evaluations of (i) how they regarded her, (ii) how they thought she regarded each of them and (iii) how they regarded themselves, so as to provide baseline measures for the study. On her next visit she formed three treatment groups by giving out her own evaluations of each child on individual cards, praising the behaviour of one third of the class, criticising another third while the remaining third received no feedback cards. The same measures were then taken a second time. From the results, children did not appear to process praise or criticism as mirror opposites. In particular, criticism appeared to be deflected into negative ratings of the teacher rather than of the self. Results are considered in terms of a selective gating hypothesis and wider implications are discussed.     

Primary humanities – a perspective from Northern Ireland

ABSTRACT

The word ‘humanities’ does not appear in the current Northern Ireland Curriculum (NIC). Geography and history are taught within an Area of Learning called ‘The World Around Us’ which also contains science and technology. The curriculum has a strong emphasis on an integrated, ‘connected learning’ way of teaching and learning. Religious Education is a separate subject that stands alongside, rather than within, the NIC, and the curriculum also includes a new Area of Learning – ‘Personal Development and Mutual Understanding’. The distinctive content and modes of teaching which the humanities subjects tend to encourage ought to be seen as particularly important in Northern Ireland – a part of the UK which has endured a complicated past and remains to a large extent segregated, both socially and educationally. This complicated past means that there is often wariness and reluctance on the part of teachers towards tackling controversial personal and social issues in the primary school.     

Development of the instrument of question-answer process (IQAP) and its application in examining salient characteristics between pre- and in-service teachers in senior high school chemistry class

The purpose of this study is to examine the salient characteristics of the ‘Question-Answer Process’ (QAP) in senior high school chemistry class between pre- and in-service teachers. We first developed the ‘Instrument of Question-Answer Process’ (IQAP), and then, applied it to compare salient characteristics of QAP between pre- and in-service teachers. Data collection consists of classroom observation and structured-interview. Participants are seven pre-service and seven in-service chemistry teachers. The results are: (a) Both pre-and in-service teachers ask most of the questions and students ask few questions; (b) Pre-service teachers ask more lower cognitive level questions, while in-service teachers ask more higher cognitive level questions; (c) Pre-service teachers tend to ask non-volunteer students while in-service teachers tend to ask volunteer students to respond; (d) Pre-service teachers tend to be ‘no feedback or ignore’ after students provide answers and both pre- and in-service teachers seldom guide students to reflect on answers; and (e) The frequency of authority of ‘student’ in pre-service teachers’ class is much higher than those in in-service teachers’ class, while the frequency of authority of ‘teacher and student’ is much lower than those of in-service teachers’ class.
