Sex is considered to be one of the most significant factors influencing attitudes towards science. However, the so-called brain type approach from cognitive science suggests that the difference in motivation to learn science does not primarily differentiate the girls from the boys, but rather the so-called systemisers from the empathizers. The present study investigates this hypothesis by using structural equation modelling on a sex-stratified sample of 500 male and female students of secondary II level. The results show, that the motivation to learn science is directly influenced by the systemizing quotient SQ, but not by sex. The impact of sex on the motivation to learn science, measured by five key concepts, only works indirectly, namely through the influence of sex on the SQ. The empathizing quotient (EQ) has no impact on the motivation to learn science. The SQ explains between 13 and 23 percent of the variation of the five key constructs. In female students, the impact of the SQ is very similar for all key concepts. In male students, it is highest for self-efficacy and lowest for assessment anxiety. The motivation to learn science is significantly larger for male students in all involved SMQ key concepts, but the difference is small. The interpretation of these findings and conclusions for science teaching and further research are discussed.  相似文献

The reasoning patterns used by a sample of Western Australian secondary school students aged 13‐16 were investigated with regard to the following reasoning modes: proportional reasoning, controlling variables, probabilistic reasoning, correlational reasoning, and combinatorial reasoning.

There was a wide range in students’ reasoning abilities at all year levels. Large percentages of students did not use formal operational reasoning patterns when they attempted to solve problems assessing their ability to use each of the five reasoning modes. Commonly used, but incorrect reasoning patterns were identified for each reasoning mode.

The students’ ability to use formal reasoning patterns was found to be an important factor in determining student achievement in lower secondary science, in their selection of year 11 science subjects, and their achievement in these subjects.

The results of the study indicate that it is important for teachers to be aware of the reasoning patterns of their students and the cognitive demands of course content, so that they can optimally match the content and their teaching strategies with the abilities of their students. Further research is needed to establish the nature of instruction which might best facilitate cognitive growth.  相似文献

Dealing with socio-scientific issues in science classes enables students to participate productively in controversial discussions concerning ethical topics, such as sustainable development. In this respect, well-structured decision-making processes are essential for elaborate reasoning. To foster decision-making competence, a computer-based programme was developed that trains secondary school students (grades 11–13) in decision-making strategies. The main research question is: does training students to use these strategies foster decision-making competence? In addition, the influence of meta-decision aids was examined. Students conducted a task analysis to select an appropriate strategy prior to the decision-making process. Hence, the second research question is: does combining decision-making training with a task analysis enhance decision-making competence at a higher rate? To answer these questions, 386 students were tested in a pre-post-follow-up control-group design that included two training groups (decision-making strategies/decision-making strategies combined with a task analysis) and a control group (decision-making with additional ecological information instead of strategic training). An open-ended questionnaire was used to assess decision-making competence in situations related to sustainable development. The decision-making training led to a significant improvement in the post-test and the follow-up, which was administered three months after the training. Long-term effects on the quality of the students' decisions were evident for both training groups. Gains in competence when reflecting upon the decision-making processes of others were found, to a lesser extent, in the training group that received the additional meta-decision training. In conclusion, training in decision-making strategies is a promising approach to deal with socio-scientific issues related to sustainable development.  相似文献

This study focused on exploring students’ and supervisors’ perceptions of ethical problems in doctoral supervision in the natural sciences. Fifteen supervisors and doctoral students in one research community in the natural sciences were interviewed about their practices and experiences in the doctoral process and supervision. We explored to what extent doctoral students and supervisors experienced similar or different ethical challenges in the supervisory relationship and analyzed how the experiences of ethical dilemmas in supervision could be understood in light of the structure and practices of natural science research groups. The data were analyzed by theory-driven content analysis. Five ethical principles, namely non-maleficence, beneficence, autonomy, fidelity and justice, were used as a framework for identifying ethical issues. The results show that one major question that appears to underpin many of the emerging ethical issues is that the supervisors and students have different expectations of the supervisory role. The second important observation is that doctoral students primarily described their own experiences, whereas the supervisors described their activities as embedded in a system and elaborated on the causes and consequences at a system level.  相似文献

One way for teachers to develop their professional knowledge, which also focuses on specific science content and the ways students learn, is through being involved in researching their own practice. The aim of this study was to examine how science teachers changed (or not) their professional knowledge of teaching after inquiring into their own teaching in learning studies. The data used in this article consisted of interviews and video-recorded lessons from the six teachers before the project (PCK pre-test) and after the project (PCK post-test), allowing an analysis of if and if then how the teachers changed their teaching practice. Hence, this study responds to the urgent call to focus direct attention on the practice of science teaching. When looking at the individual teachers, it was possible to discern similarities in the ways they have changed their teaching in lesson 2 compared to lesson 1, changes that can be described as: changes in how the object of learning was defined and focused, changes in how the examples that were presented to the students were chosen and changes in how the lessons were structured which in turn influenced the meaning of the concepts that were dealt with. As such, issues for enhancing teachers’ professional learning were unpacked in ways that began to demonstrate, and offer insights into, the extent of their PCK development over time.  相似文献

Respect means consideration of actions and requests of others and confirmation of values of others. School is a social institution where students are equipped with knowledge and skills, as well as fundamental character attributes. Respect among students, teachers, administrators, parents, and other staff at schools is of importance. In this study, the focus group method, including 12 principals and 10 teachers at state primary schools, was employed to explore respect in principal–teacher relations. According to the findings, the participants generally developed professional respect understanding. The teachers presented different definitions of respect associated with hierarchical relations. The participants’ respect behaviors were commonly observed in positive communication and self-improvement. The principals displayed respect for teachers through some guarding behaviors, and the teachers displayed profession-related respect behaviors. The common respect expectations of the participants were as follows: self-improvement, establishment of positive social relations, and unbiased behavior. While the school principals expected obedience and complete fulfillment of assigned tasks from teachers, the teachers expected civility, justice, and guarding administration from principals. The participants regarded improper appearance, behaviors contradictory to rules of good manners and bad habits as disrespectfulness. The school principals regarded abuse of goodwill and false excuses by teachers as disrespectfulness; whereas the teachers regarded oral or behavioral insults by school principals and intervention in their private life as disrespectfulness.  相似文献

ABSTRACT

A great deal of information and many services can now be accessed digitally. In order to make use of such services, however, it is necessary to have some form of Internet access. A lack of involvement in digital society may produce new forms of social exclusion. Older adults are particularly at risk of Internet-related social exclusion, since they tend to use the Internet less than younger adults. Little is known, however, about whether this lower level of Internet use among older people is in fact accompanied by a sense of social exclusion. In order to investigate the subjective sense of digital social exclusion resulting from a lack of Internet usage, we conducted a secondary analysis of a representative, cross-sectional telephone survey of 1,037 adults aged 65 years and over and living in Switzerland. We found that 33% of “onliners” reported that they would feel socially excluded were they to stop using the Internet, compared with 14% of “onliners” who felt socially excluded on account of their lack of Internet use. Our analyses show that onliners’ attitudes toward Internet use and the variety of online applications available were related to their sense of social exclusion. By contrast, offliners’ attitudes toward Internet use and their feelings of loneliness in general were predictors for their sense of social exclusion as a result of not using the Internet. The results of the study as well as its implications for research and practice are discussed.  相似文献

The purpose of this article was to describe a Finnish research project concerning communicative spontaneity in pupils with autism spectrum disorder (ASD). ASD is a behavioural syndrome which is neurobiological in origin and which involves atypical developmental dysfunctions in the brain. The essential features are persistent impairment in reciprocal social communication and social interaction, and restricted, repetitive patterns of behaviour, interest, and activities. However, an important part of flexible interaction is functional communication between partners, and spontaneity is a critical aspect of functional communication. Communicative spontaneity can be assessed by examining the relationship between environmental antecedents or cues (prompts) and communicative acts. In this study spontaneity is viewed along a continuum, it is, all communicative acts are considered to have some degree of spontaneity and all communication is environmentally prompted or cued. In this research a model of supportive prompts for spontaneity was applied in practice. The model in question is Carter and Hotchkis’s four-level antecedent model. The study explored the supportive prompts ethnomethodologically. In the study described six video recordings (each about 30?min) from authentic classroom situations were categorised with the four-level antecedent model. These videos are unusual in Finnish context in that they involve only the teacher and her six pupils with ASD; no helpers are present in the classroom. This study indicated that the four-level antecedent model is a powerful means of analysing the dimensions of spontaneous communication, but the sensitivity of the model can be increased. The authors’ suggestion is that the modification of the model may be accomplished by adding new categories (such as non-acting or prompt-seeking behaviour) or editing current categories. The modified four-level antecedent model is more applicable to help teachers develop spontaneity in the communication of pupils with ASD.  相似文献

This article describes a national school improvement project involving five compulsory schools for hard‐of‐hearing pupils, located in different parts of Sweden. Using action research, the teachers tried to change the communication patterns among the pupils by changing their own classroom practices, In this process the teachers tested and used different tools, such as writing, shadowing and facilitating each other, over a three‐year period. The purpose of this article is to examine how tools used in action research can be used to promote learning in relation to the concept of the zone of proximal development. The theoretical framework of the study is based on action research, as a collaborative way of creating knowledge, and on sociocultural learning theories. The basic assumption is that teachers, by using different tools, also challenge each other’s learning. The results show the importance of internalising tools that become owned by individuals or communities of practise. To be able to assume an active role in the zone of proximal development, and to produce knowledge collaboratively, a meaning‐making process was needed. It was found that this could be realised if the participants had an awareness of how to function as a critical friend among colleagues. Furthermore, the results revealed that, by using different tools, different voices can be heard. Three categories of voices were identified.  相似文献
