The purposes of the study were to analyse the promotion of scientific literacy through practical research activities and to identify children's conceptions about scientists and how they do science. Elementary school children were engaged in two scientific experiments in a marine biology research laboratory. A total of 136 students answered a questionnaire about their previous habits towards science and carried out the following actions: (1) a guided visit to the laboratory, (2) a brief presentation of the research theme, (3) the development of two experiments, and (4) a questionnaire about the experiments and science conceptions. The research methods included observation, document analysis, and content analysis of the answers to the questionnaires. Additionally, each visit was video recorded in order to design learning materials. The results revealed that most of the pupils were able to follow every stage of experimentation. However, some of them misinterpreted results and conclusions. One implication of the study is that this type of outdoor activity is extremely important to promote meaningful science learning in children, but more care should be taken in practical science activities so that children can overcome some common difficulties when performing scientific inquiry.  相似文献

Abstract

Finland's Ministry of Education sponsored the development of an environmental education (EE) course for practicing educators of teachers. One to 3 persons from each teacher training unit at various universities and training schools attended a tutor training session, during which a course for other teacher trainers was developed. The course focused on personal development and curriculum development. Tutors used distance education with some locally arranged contact teaching to teach the course. Tutors also led local study groups. Teacher trainers who attended the course learned and applied new teaching practices and produced new model lessons. They also reflected on their personal environmental philosophy and gained in environmental knowledge. Preliminary evaluation of the program indicated that high-quality learning experiences occurred. This 2-step distance education model could be used for large-scale implementation of EE for in-service teacher training.  相似文献

A study was performed to describe and analyze the conceptions about teaching and learning science held by different samples of teachers in Spain. The responses of 265 teachers (107 prospective teachers and 158 active teachers) to items from the Inventory of Scientific and Pedagogical Beliefs (Porlán, 1989) were subjected to multifactorial analysis. The results showed various tendencies in how the teaching/learning process is viewed, ranging from a predominant view based on the transmission-reception of knowledge to a minority constructivist view. There was a greater diversity of viewpoints among the in-service teachers than among the prospective teachers. In both samples, the most representative tendency was learning as appropriation of meanings, followed by a technical view of teaching among the prospective teachers and a more traditional view among the in-service teachers. Finally, some implications for teacher education are discussed.  相似文献

The main objective of this paper is to show to what extent and why students with the same academic aptitude but different social backgrounds have different odds of entering university. For our analysis, we separated primary and secondary factors of social origin in the formation of educational inequalities. The results show that the primary and secondary factors have approximately the same influence on the transition to university. Czech schools do not affect the process of forming educational aspirations and transition to university, and merely ‘classify’ children according to their social origin. This situation emerged during the socialist era and has remained unchanged after the fall of communism (in 1989). However, the mechanism of the social origin effect has changed – while cultural capital with a ‘direct’ impact had a major role to play during the socialist era, at present there is a rather ‘indirect’ influence through economic capital.  相似文献

This paper analyses the changes found in students’ involvement in homework throughout the four grade levels of compulsory secondary education in Spain (ages 12–15). It also analyses the relationship between the changes in students’ involvement in homework throughout schooling and motivational and emotional variables related to homework. Findings indicated that: (a) the amount of homework completed and homework time management diminished slightly throughout the grade levels researched; however, this result is clearer in terms of the amount of homework completed; (b) prior academic achievement is significantly related to the variables associated with students’ involvement in homework; (c) the motivational and affective variables researched explained statistically significant variance related to two of the three dependent variables associated with involvement in homework; and (d) the association between the motivational and affective variables and involvement in homework is lower.  相似文献

Research on masculinity has become an important area of gender and education that includes a wide range of empirical concerns and theoretical approaches. This article identifies a number of studies that are asking questions about the conceptual usefulness of masculinity within educational contexts. The first section explores how educational researchers are beginning to suggest alternative ways that hegemonic masculinity may be configured. The second section draws upon work that interrogates the disconnection of gender from sex. Such work considers the importance of understanding schooling worlds through an untethering of gender categories from physical bodies. The third section suggests the possibility of a post-masculinity position by exploring research that questions the viability of masculinity as a conceptual frame to understand gender. In conclusion, the paper argues that such developments can be used heuristically to inform the critical reflexiveness of future research in the area.  相似文献

In a series of related experiments, we studied associative phenomena in snails (Helix aspersa), using the conditioning procedure of tentacle lowering. Experiments 1A and 1B demonstrated a basic conditioning effect in which the pairing of an odor (apple) as the conditioned stimulus (CS) with the opportunity to feed on carrot as the unconditioned stimulus (US) made snails exhibit increased levels of tentacle lowering in the presence of the CS. Experiments 2 and 3 showed that the magnitude of the conditioning was reduced when snails were exposed to the CS prior to the conditioning trial (a latent inhibition effect). Experiment 4 examined the effects produced by pairing a compound CS (apple—pear) with food presentations and demonstrated the existence of an overshadowing effect between the two odors. Experiment 5 revealed that pairing one CS with another previously conditioned stimulus increased tentacle lowering to the new CS (a second-order conditioning effect). Finally, Experiment 6 showed that pairing two odors prior to conditioning of one of them promoted an increase in tentacle lowering in response to the other (a sensory preconditioning effect). The results are discussed in terms of an associative analysis of conditioning and its implications for the study of cognition in invertebrates.  相似文献

The goal of our research was to study different forms of organization of pretend play on children's cognitive performance in a mixed-age environment. We studied two forms of management of the playing process: (a) teacher-directed play with simultaneous involvement of all children in the classroom, where the teacher plays the dominant role in the education process directing children's activity, and (b) child-directed play in various small groups. Twenty-six observations were performed on 51 children in two mixed-age classrooms. The mean age of the children was 4.6 years, with age span from 3 to 6 years. Data were collected regarding children's affective and cognitive behavior according to generally accepted taxonomies: Bloom for the cognitive domain, and Krathwohl for affective domain. We found a significant increase in cognitive manifestations during direction of the playing process in groups compared with frontal management of the lesson (113.1 ± 12.1 vs. 45.7 ± 10.3, mean ± SEM, p < 0.0001), which is related with better employment of the powerful education engine of the free-play children.  相似文献

Movement is key to human physical and mental maturation, hence the importance of non-delayed psychomotor development. Psychomotor development occurs much later in children with Down Syndrome (DS) as compared with typically developing children. The objective of this research is to assess the effectiveness of an intervention programme aimed at the psychomotor development of preadolescents with DS (Experimental Group = 5, Control Group = 5), focusing on body schema and spatio-temporal structure. Results show a significant increase in body awareness as well as in concepts of space and quantity. Nevertheless, it is necessary to consolidate these motor abilities in a personalized and more prolonged way in order to minimize psychomotor developmental delays.  相似文献

The goal of this study was to determine the effect of setting a delay between reading a text and answering comprehension questions on when-to-search and what-to-search decisions in a task-oriented reading environment. Fifty-five eighth-grade students were randomly divided into two groups. One group read one text, answered comprehension questions regarding the text with the text available, and subsequently repeated the procedure with a second text (immediate condition). The other group read both texts first and then answered, with the texts available, the questions for the first text and then for the second text (delayed condition). In both conditions, the readers’ actions during the task were recorded. The results demonstrated that the students in the delayed condition made more search decisions. In addition, moderated mediation analyses indicated that setting a delay had a positive indirect effect on performance via increased searching only for the students with average and high comprehension skills. Moreover, decisions regarding what information to search for depended exclusively on comprehension skill. Instructional implications are discussed.  相似文献
