Modern biotechnology will have a large impact on society and requires informed decision‐making and critical attitudes toward biotechnology among the public. This study aims to explore these attitudes in secondary education. For this purpose, a questionnaire was constructed according to the general tripartite theory of attitudes. A total of 574 Dutch secondary school students completed the questionnaire. Based on principal component analyses, several distinct and independent cognitive, affective, and behavioural factors were found, demonstrating that attitudes towards biotechnology are a multi‐component concept. In a cluster analysis on these factors, we found four interpretable clusters representing different groups of students. The four groups are labelled “confident supporter” (22%), “not sure” (42%), “concerned sceptic” (18%), and “not for me” (17%). These results indicate that there is a diverse appraisal of modern biotechnology among secondary school students. Suggestions for educational interventions are made. 相似文献

Empirical investigations on students’ conceptions of cell biology indicate major misunderstandings of scientific concepts even after thorough teaching. Therefore, the main aim of our research project was to investigate students’ difficulties in learning this topic and to study the impact of learning activities on students’ conceptions. Using the Model of Educational Reconstruction, a four‐phase design was carried out. Firstly, there was the clarification of science subject matter. Secondly, students’ conceptions were investigated, and finally, the learning activities were designed. An evaluation of these learning activities was carried out using five teaching experiments, each with three 9th grade students (15–16 years, Grammar school). Interpretation of students’ “pathways of thinking” and their conceptual change during instruction was framed theoretically by experiential realism. Theoretical framework, methods and outcomes of the study may contribute to a deeper understanding of students’ ways of thinking in the field of cell biology and reveal the process of conceptual development by using well planned learning activities. 相似文献

In this paper, we employ quantitative and qualitative content analysis to investigate the nature of humanistic value content
in the Chinese language arts curriculum and whether or not this varies across old and new versions of the textbooks. Our findings
illustrate the various dimensions of humanistic value content in the Chinese language arts curriculum and suggest that there
is as much variation across different versions of the new textbooks as there is between old and new versions of the curriculum. 相似文献

AbstractConceptual modeling of bibliographic data, including the FR models and the consolidated IFLA LRM, has provided an opportunity to shift focus to entities and relationships and to support hierarchical work-based exploration of bibliographic information. This paper reports on a study examining the complexity of a work's bibliographic family data and user interactions with data visualizations, compared to traditional displays. Findings suggest that the FRBR-based visual bibliographic information system supports work families of different complexities more equally than a traditional system. Differences between the two systems also show that the FRBR-based system was more effective especially for related-works and author-related tasks. 相似文献

The aim of the article is to present and discuss a study in which Finnish, English and Swedish pupils’ understanding of citizenship education with regard to: (a) political literacy; and (b) attitudes and values was explored. The study was a cross‐national, multiple case study and data were collected through 18 focus group dialogues with 15‐year‐old pupils. Results showed that English pupils were much more well‐informed about rights and responsibilities than their Nordic counterparts and also more skilled rhetorically, but appeared less accustomed to open and confident relationships with adults than the Swedish pupils. Finnish pupils did not seem to be encouraged to talk; instead they kept their thoughts and feelings to themselves. One conclusion, among others, was that the study illuminates conditions for the development of a so‐called key competence – i.e., ‘interpersonal, intercultural, social and civic competence’. 相似文献

Collective efficacy can be defined as a group's shared confidence that they will successfully achieve their goal. We examined which behaviours and events are perceived as sources of collective efficacy beliefs in a volleyball context. In study 1, volleyball coaches from the highest volleyball leagues (n = 33) in Belgium indicated the most important sources of collective efficacy. This list was then adapted based on the literature and on feedback given by an expert focus group, resulting in a 40-item questionnaire. In Study 2, coaches and players from all levels of volleyball in Belgium (n = 2365) rated each of these sources on their predictive value for collective efficacy. A principal component analysis revealed that the 40 sources could be divided into eight internally consistent factors. Positive supportive communication (e.g., enthusiasm after making a point) was identified as the factor most predictive for positive collective efficacy beliefs. The factor referring to the negative emotional reactions of players (e.g., discouraging body language) was the most predictive for negative collective efficacy beliefs. These findings offer a starting point for the design of continuous measurements of collective efficacy through observation. 相似文献

Introduction:
We present our work of monitoring 202 different patients with markedly elevated serum index for lipemia whereby serum samples were clear. We tried to clarify the cause of occurrence of these indices which were detected in the years 2006–2010 on Siemens Dimension analyzers.Materials and methods:
In samples with unusual lipemia index we measured the concentration of lipids (total cholesterol, triglycerides, HDL and LDL cholesterol, Lp(a), ApoA1, ApoB), total proteins and checked for possible interferents (rheumatoid factor, immunoglobulins). We performed serum protein and immuno- electrophoresis. We investigated the repeatability of unusual lipemia indices during the day and after different time periods and we compared them on four different analyzers (RXL Max, Vista, Hitachi 911 and former Olympus AU640).Results:
In 87% of 202 samples we found a monoclonal or biclonal peak in serum protein electrophoresis. Different types of paraproteins were confirmed with immunofixation electrophoresis. In the remaining 13%, polyclonal elevated concentrations of immunoglobulins were measured. Other parameters had no influence on appearing of these indices. The repeatability of indices was good during the first day of measurements (P values > 0.05) and markedly lower in the next days or after 3 and 12 months (P values < 0.05). The indices were elevated only on Dimension analyzers, but not on Hitachi and former Olympus analysers.Conclusion:
A markedly elevated lipemia index in a clear serum sample measured on Siemens analyzers Dimension indicates a high possibility for the presence of a paraprotein in the sample. 相似文献49.

ABSTRACTResearch indicates that children with hearing impairment are at higher risk regarding their social participation in school compared to their hearing peers. The purpose of this study was to investigate the social participation of 7th Grade students with hearing impairment in inclusive classrooms. Data from 62 7th Grade students across three classrooms and teachers were collected via paper-and-pencil questionnaires and from regular and special needs teachers via interviews. Results from the single case studies in three classrooms indicate that students with hearing impairment feel less socially integrated and less accepted by their peers. They do, however, interact more with other students with special needs and most students with hearing impairment have friends in their class. Teachers evaluated social integration, acceptance, interaction and friendships of their students with hearing impairment as average or as above average. The teachers’ evaluations only partly correspond to the self-perceptions of the students. Factors that either promote or hinder participation on an institutional, teacher, teaching and student level were exposed, which may have important practice and policy implications. 相似文献

We examined the effectiveness of video-based decision training in national youth handball teams. Extending previous research, we tested in Study 1 whether a three-dimensional (3D) video training group would outperform a two-dimensional (2D) group. In Study 2, a 3D training group was compared to a control group and a group trained with a traditional tactic board. In both studies, training duration was 6 weeks. Performance was measured in a pre- to post-retention design. The tests consisted of a decision-making task measuring quality of decisions (first and best option) and decision time (time for first and best option). The results of Study 1 showed learning effects and revealed that the 3D video group made faster first-option choices than the 2D group, but differences in the quality of options were not pronounced. The results of Study 2 revealed learning effects for both training groups compared to the control group, and faster choices in the 3D group compared to both other groups. Together, the results show that 3D video training is the most useful tool for improving choices in handball, but only in reference to decision time and not decision quality. We discuss the usefulness of a 3D video tool for training of decision-making skills outside the laboratory or gym. 相似文献
