Comparison of student learning about diffusion and osmosis in constructivist and traditional classrooms

Student learning about diffusion and osmosis was measured at three different universities using a newly developed instrument [Odom and Barrow (1995) Journal of Research in Science Teaching, 32, 45-61] which tests the underlying knowledge of students in addition to their ability to answer factual questions correctly. Instructors at two of the universities taught utilizing the very common large lecture/small laboratory approach. The instructor at the third university taught using a small discussion/laboratory approach which was informed by constructivist theory. Results of pre- and post-testing indicate that students learned about and understood diffusion and osmosis most deeply in the small discussion/ laboratory course. Reasons why this may be are discussed and suggestions are presented to help improve student learning in other settings.     

The pedagogic signature of special needs education

The goal of the following study is to identify a pedagogic signature, according to LS Shulman, for working with students who have special educational needs. Special educational needs are defined as significant limitations in personal development and learning which require particular educational measures beyond regular education. The development of a pedagogic signature should create an identity and provide guidance, particularly for teachers who are working in the context of inclusive schools with no prior knowledge or training in this regard. The study is carried out against the background of the structural uncertainty of the teaching profession and takes into consideration existing normative, theoretical and empirical approaches in education. Existing research regarding demands is largely theoretical, while empirical research is rudimentary. The present study used a multi-method approach to identify demands for working with students with special educational needs. Experts in the areas of learning disabilities and emotional/behavioural disorders completed an instrument from the field of industrial and organisational psychology, quantifying and weighting professional demands on teachers according to their importance. The results were added and validated through group discussions, creating a demand profile. By combining the results with the dimensions of a signature pedagogy, according to Shulman, it is apparent that surface structure and deep structure play a minor role in the perceptions of special needs teachers. The central importance of the implicit structure is characteristic of the pedagogic signature. This importance is represented by the target group’s emphasis on demands such as having an appreciative leadership or authenticity. An even greater emphasis is placed on the aspect of attitude – this is having a humanistic ethos. The demand profile and the resulting consequences for the practice of teaching will be considered with a view towards current problems and questions in research and practice, and particularly with regard to inclusion.     

The Compass Rose Effectiveness Model

The effectiveness model focuses the institution on mission achievement through assessment and improvement planning. Eleven mission criteria, measured by key performance indicators, are aligned with the accountability interest of internal and external stakeholders. A Web-based performance assessment application supports the model, documenting the impact of strategic planning on continuous improvement.     

Comparison of sadness, anger, and fear facial expressions when toddlers look at their mothers

Research suggests that sadness expressions may be more beneficial to children than other emotions when eliciting support from caregivers. It is unclear, however, when children develop the ability to regulate their displays of distress. The current study addressed this question. Distress facial expressions (e.g., fear, anger, and sadness) were examined in 24-month-old toddlers throughout 4 episodes as well as specifically during looks to their mothers. Consistent with hypotheses and the literature, toddlers expressed sadness more frequently and with more intensity than target emotions only during looks to their mothers. These findings indicate that toddlers as young as 24 months of age are using particular emotional displays to elicit support from the social environment.     

Children exposed to obscene phone calls: what they remember and tell

OBJECTIVE: This case study examined children's reports from an obscene phone call (i.e., a verbal sexual abuse). We investigated which type of information the children reported, the completeness and accuracy of the children's statements, and whether there were systematic patterns in terms of memory distortions and omissions. METHOD: The completeness and the accuracy of the children's statements were examined by matching 64 children's statements given during police interviews with a detailed documentation of each phone call, made by the perpetrator during the actual phone calls. RESULTS: All children remembered the phone call per se, but they were found to omit almost all of the sexual and sensitive information (perpetrator's questions and statements) and about 70% of the neutral information given by the perpetrator. However, the children were accurate in the information they did report. CONCLUSIONS: The fact that the children did remember more of the neutral information suggests that they actually remembered the sexual information as well, but that they chose not to report it. Results indicate that children who have been sexually abused may remember more than they report in an initial interview. One possible underlying reason is that children experience shame or embarrassment.
