The aim of this paper is to investigate in a systematic and comparative way previous results of independent studies on the treatment of genes and gene function in high school textbooks from six different countries. We analyze how the conceptual variation within the scientific domain of Genetics regarding gene function models and gene concepts is transformed via the didactic transposition into school science textbooks. The results indicate that a common textbook discourse on genes and their function exist in textbooks from the different countries. The structure of science as represented by conceptual variation and the use of multiple models was present in all the textbooks. However, the existence of conceptual variation and multiple models is implicit in these textbooks, i.e., the phenomenon of conceptual variation and multiple models are not addressed explicitly, nor its consequences and, thus, it ends up introducing conceptual incoherence about the gene concept and its function within the textbooks. We conclude that within the found textbook-discourse ontological aspects of the academic disciplines of genetics and molecular biology were retained, but without their epistemological underpinnings; these are lost in the didactic transposition. These results are of interest since students might have problems reconstructing the correct scientific understanding from the transformed school science knowledge as depicted within the high school textbooks. Implications for textbook writing as well as teaching are discussed in the paper. 相似文献

Textbook analysis is seen as a major element for studying environmental education addressing pupils, image analysis being rather relevant when studying textbooks written in 11 languages. We analysed 25 textbooks from 14 countries addressed to 14–16-year-old pupils, focusing on: (1) local and foreign/global images; (2) urban/rural and nature images; (3) negative impact, human management, and the beauty of nature; and (4) men and women in images with negative and positive impact. We distinguished some trends between Western (WEc) and Eastern (EEc) European countries and non-European countries (NEc). In contrast to textbooks from EEc and NEc, which tend to show the beauty of nature with little human influence, WEc textbooks tend to exhibit more images of urban/rural landscape, of human negative impact and of human management, expressing an anthropocentric view of the environment. Men are usually more present in textbook images than women. However, some images exhibiting more women than men could be found in textbooks from WEc and EEc, but never in NEc. In negative impact pictures, men are more often present than women but NEc women are never present in such images. Women are more frequent than men in positive impact images. Results suggest that textbooks from EEc and NEc should give more emphasis to human management and urban/rural images, whereas those from WEc should give more attention to the beauty of nature. A balance in the presence of men and women in images should be a matter of greater concern by all textbooks’ authors and publishers. 相似文献

The relationships between reasoning and school achievement were studied taking into account the multilevel nature (school- and class-levels) of the data. We gathered data from 51 classes at seven schools in metropolitan and Eastern Finland (N = 769, 395 males, 15-year-old students). To study scientific reasoning, we used a modified version of Science Reasoning Tasks, tapping control-of-variable schemata. Analyses were conducted by MLwiN2.10 multilevel modelling. The present results showed that the intra-class correlation coefficient (ICC) of schools for scientific reasoning is 7% and that the corresponding ICC of classes is 10%. Whereas the first finding confirms earlier PISA results, the second finding provides new insights into class variation within schools. In practice, class composition seems to be an efficient solution to meeting the differing needs of individual students. 相似文献

The purpose of the present study was to examine whether mother-child communication patterns vary as a function of the type of the task. Groups of learning disabled (LD=30) and normally achieving boys (NLD=30) were videotaped interacting with their mothers in two different tasks. The children were matched for age (8 to 11 year-olds) and for parent’s SES. The results indicated that the teaching task differentiated the groups more than did the story task. Academic character of the teaching task increased mothers’ task involvement in both groups. Mothers of the LD group showed, however, significantly more dominance and expressed less emotionality while teaching their child. Mothers’ interaction partly followed from their children’s behaviour on this task. The children with LD did not cooperate with their mothers and were not emotionally involved in the teaching task as highly as were the normally achieving children. Corresponding features of interaction were not found for the LD group in the story task. Consistency of children’s communication across the tasks was significant in the LD group. The normally achieving boys were more responsive to changes in task conditions showing different behavior as a function of task. 相似文献

The authors voice teachers' perceptions of their interpersonal experiences with students in both positive and problematic relationships. Interview data from 28 teachers were examined by coding utterances on teacher and student interactions. Results indicate that teachers defined the quality of the relationship mostly by the level of communion (friendly vs. hostile), instead of by the level of agency (in control vs. powerless). Analyses of mentioned teacher and student behavior show a friendly interactional pattern for positive relationships and a hostile pattern for problematic ones. In teachers' perceptions, positive and problematic relationships also differed in context where encounters take place and topic of talk. Contrary to interactions in problematic relationships, encounters in positive relationships were mostly situated outside the classroom context and conversations during these encounters covered a wide range of topics. Implications for teacher education programs are discussed. 相似文献

The study examined the predictive value of adolescents’ personality trait ratings by different groups of informants in explaining academic achievement [grade point average (GPA)] while controlling for students’ sex and their mothers’ education. The Inventory of Child/Adolescent Individual Differences was employed as a measure of students’ personality traits at the end of elementary schooling (mean age = 14.7 years) and two years later when the participants attended secondary schools. The trait ratings were obtained through self‐, maternal and peer reports at both measurement occasions. They explained substantial portions of unique variance in the students’ GPA concurrently, and over time. Ratings by each of the three groups of informants had an incremental validity over one another in predicting school grades. Among personality variables, conscientiousness and low extraversion were consistently predictive of GPA. 相似文献

This study investigated whether mathematics education based on a multi-tiered response to intervention (RTI) model can support students' arithmetic competence in primary schools in Sweden. The intent was to identify and support students at risk of failure. In this study, 113 students participated in the intervention, and 30 students participated in the control group. Both groups were followed from Grade 1 to the end of Grade 2 and compared. During the first semester in Grade 1, all students were taught basic addition and subtraction with explicit instructions in Tier 1. Those who did not respond to Tier 1 after one semester were provided support within Tier 2 during the second semester. The same was repeated in grade 2 and the students that did not respond to Tier 2 were supported within Tier 3. At the end of Grade 2, students in the intervention group performed significantly higher on the basic arithmetic competence in the number range 1–9 than the control group. No significant difference was found in a test measuring basic arithmetic competence in the number range 10–19. This study shows that using multi-tiered RTI might be sufficient to identify and support students at risk in early arithmetic competence. 相似文献

Children's outdoor play is declining, despite clear links between play, learning and development. Alternative learning initiatives which provide children with a diversity of play opportunities, including the chance to play outdoors, are therefore needed. One such programme, Forest School, is increasing in popularity in the UK and internationally, yet little is understood about its impact on children's learning, or how alternative approaches are informing learning in mainstream settings. This novel study examined primary school children's experiences of engaging in a Forest School programme in relation to this intersection between formal and informal approaches to learning. It explored how children interpret their experiences when faced with a fusion of learning environments and critically evaluates the benefits children realise, when asked to reflect on their learning engagement in both classroom and outdoor settings. Interviews were conducted with 33 children from two mainstream primary schools in England who had recently completed a 6-week Forest School programme. A rigorous phenomenological thematic analysis revealed three inter-related themes: a break from routine; learning through play; collaboration and teamwork. The findings suggest that the blending of Forest School with mainstream settings contributes to children's social, cognitive, emotional and physical skill development through experiential learning using play. These findings are significant because they not only emphasise the values of social constructivist play-pedagogy which underpin Forest School practice, but also highlight the need for primary schools to consider learning outside of the classroom as an effective pedagogy. 相似文献
