Can Animals See Colours

Scientists think that many-perhaps most-ammals can not see colors. The world is black and white to them. To find out if dogs could, see colors, scientist gave dogs food every time they played a certain piece of music. The dogs got ready to eat only when they heard this piece of music. They did not get ready to eat when they heard other pieces of music.

Psychophysiological and behavioral evidence for varying forms and functions of nonsocial behavior in preschoolers

Four-year-old children showing low levels of social behavior in a laboratory play session with unfamiliar peers were classified as reticent (unoccupied or onlooking behaviors) or solitary-passive (solitary constructive or exploratory play). Compared with a group of more social children, the children in both low-social groups were rated high on maternal reports of shyness and displayed a pattern of right frontal EEG asymmetry. However, only the reticent group was elevated on measures indicative of a fearful temperament, both concurrently and retrospectively. A subset of children in the solitary-passive group showed increasing levels of reticent behavior over the course of the visit, suggesting that for some children solitary-passive behaviors provide a means for coping with feelings of unease.     

Silences of ethical practice: dilemmas for researchers using social media

Social media, such as social network sites and blogs, are increasingly being used as core or ancillary components of educational research, from recruitment to observation and interaction with researchers. However, this article reveals complex ethical dilemmas surrounding consent, traceability, working with children, and illicit activity that we have faced as education researchers for which there is little specific guidance in the literature. We believe that ethical research committees cannot, and should not, be relied upon as our ethical compass as they also struggle to deal with emerging technologies and their implications. Consequently, we call for researchers to report on the ethical dilemmas in their practice to serve as a guide for those who follow. We also recommend considering research ethics as an ongoing dialogical process in which the researcher, participants, and ethics committee work together in identifying potential problems as well as finding ways forward.     

Promoting staff support in schools: Solution Circles

The Solution Circle (SC) approach is a flexible tool which encourages participants to maintain a positive, creative approach to problem-solving. This project focussed on the introduction of this approach to staff in a primary and a secondary school. The rationale was to implement a problem-solving/discussion tool that would allow staff to utilise expertise present within the school before looking to outside agencies for support. In both schools staff participants reported positively about the process, highlighting its potential use to promote the inclusion of pupils with a wide range of needs.     

Conversation and Conflict: Supporting Authentic Dialogue in the Classroom

This paper presents an exploratory study of MSW students who self‐identified as having political/religious world views differing from what they perceived to be dominant at their school. A goal was to learn about conditions that fostered or inhibited authentic speech for those students. A secondary goal was to learn how students dealt with their political views differing from political positions taken by the profession. Eleven student volunteers participated in structured interviews. Qualitative analysis of these allowed the construction of themes concerning both how faculty may discourage and how faculty support expression of minority views.     

Emotionally Intense Science Activities

Science activities that evoke positive emotional responses make a difference to students’ emotional experience of science. In this study, we explored 8th Grade students’ discrete emotions expressed during science activities in a unit on Energy. Multiple data sources including classroom videos, interviews and emotion diaries completed at the end of each lesson were analysed to identify individual student's emotions. Results from two representative students are presented as case studies. Using a theoretical perspective drawn from theories of emotions founded in sociology, two assertions emerged. First, during the demonstration activity, students experienced the emotions of wonder and surprise; second, during a laboratory activity, students experienced the intense positive emotions of happiness/joy. Characteristics of these activities that contributed to students’ positive experiences are highlighted. The study found that choosing activities that evoked strong positive emotional experiences, focused students’ attention on the phenomenon they were learning, and the activities were recalled positively. Furthermore, such positive experiences may contribute to students’ interest and engagement in science and longer term memorability. Finally, implications for science teachers and pre-service teacher education are suggested.
