Peer supervision is a method which enables the counselors to be involved in a continuous learning process throughout their professional career and not only when they are in training. It is a personal way of learning in which a pair or a small group of colleagues gives supervision to one another. In this article some advantages, potential pitfalls and conditions or ``guidelines' that should be followed to ensure the most effective peer supervision experience are discussed. An effective evaluation can greatly improve the process of peer supervision and can successfully minimise potential obstacles and pitfalls. Hence, in the second part of the article we describe the internal evaluation of the peer supervision process and illustrate it with some results of final evaluations from four peer supervision processes. 相似文献

The purpose of the investigation was to determine the meanings attached by students to the different kinds of molecular structure representations used in chemistry teaching. The students (n = 124) were from primary (aged 13-14 years) and secondary (aged 17-18 years) schools and a university (aged 21-25 years). A computerised 'Chemical Visualisation Test' was developed and applied. The research indicates that students' appreciation of three-dimensional molecular structures differs according to the kind of representation used. The best results were achieved with the use of concrete, and pseudo-concrete types of representations (e.g. three-dimensional models, their photographs, computer-generated models). However, the use of more abstract types (e.g. schematic representations, stereochemical formula) was less effective. A correlation between students' results on the Chemical Visualisation Test and their educational level, spatial visualisation, and spatial relations skills was shown statistically, but no statistically significant gender differences were observed. 相似文献

Historic parchment is a complex biological material, and due to various methods of production or inks used, unknown environmental histories of objects and heterogeneous nature of animal skin, it represents a particular analytical challenge. Due to the number of variables it is likely that patterns in degradation of these historic objects can only be revealed by surveying the material properties of a significant number of real objects. In this work, a sacrificial collection of ca. 100 historic parchments (fifteenth to twentieth century) was characterized using a range of techniques available to conservation practitioners that can usefully be used to reliably and rapidly characterize parchment. We focused on micro-destructive methods, such as shrinkage temperature (Ts), as the most widely used indicator of parchment degradation. Lipid content, roughness, and ink pH were additionally measured, while a limited number of samples containing iron gall ink were also examined using scanning electron microscopy (SEM) and SEM-EDX, to explore the distribution of ink components. Even in the absence of detailed environmental histories, it is possible to acknowledge the significance of the effect of iron gall ink and its acidity, and of lipids on parchment degradation, as measured using Ts. This research reports valuable reference data, while the collection remains accessible for further research. 相似文献

Previous studies suggest that parental involvement in children’s mathematics education is more established for parents who feel competent in mathematics. This qualitative study aimed to gain an in-depth insight into the experiences of parental involvement of two different groups of parents: those who are mathematicians and those who are not. Data were collected through narrative interviews with parents. A thematic analysis of the data revealed findings within two distinct but interrelated themes: parents’ mathematical experiences and parental involvement in their children’s mathematics education. The findings indicated that the two groups of participating parents differ in their own experiences of mathematics as well as in their parental involvement. The main difference in parental involvement was indicated in the area of children’s school mathematics, since mathematician parents, compared to non-mathematician parents, according to their narratives almost never get involved in their children’s mathematics homework. In addition, the data revealed a large gap in the coverage and content of the mathematical activities that parents in both groups provided to their children. 相似文献

Social skills of students with special needs play a very important role in their successful integration into inclusive learning environments. The aim of present empirical research was to establish whether students with learning disabilities (LD) attending grades 7–9 of regular primary school in Slovenia experience difficulties in social skills compared to their peers without LD. The following measuring instruments were used: the Questionnaire about Interpersonal Difficulties for Adolescents, the Social Anxiety Scale for Adolescents and the Self-Concept Scale. The basic research findings indicated statistically significant structural differences between the students with LD and their peers. The two groups differ in terms of difficulties in social interaction. Students with LD experience more difficulties. Statistically significant differences between the groups also appeared in tension and inhibition in social contact and social anxiety, as well as in the area of self-concept: students with LD are more anxious and reserved in social contacts. 相似文献
