The purpose of this study is to identify how upper secondary school French students (Grade 10–12) interpret chemical transformation with regards to the changes within molecules and atoms, and in terms of intramolecular and/or intermolecular bond breaking. In order to identify and describe the students’ assimilated knowledge, four questions were asked to 930 students using a written questionnaire submitted a long time after the related teaching took place. There is much research into student learning in the concept areas discussed here (atoms and molecules, chemical change, chemical bonding), as reviewed in the paper. The present study presents data from an educational system where limited work has been reported in the international literature. The French system has its own unique curriculum, and is taught in the national language (where much of the existing research has concerned learning in Anglophile systems). The research reported here found that French secondary students experienced many similar difficulties in understanding these key scientific concepts to those that have been reported elsewhere, showing the cross‐cultural nature of the key educational issues. For example, many have difficulties in understanding the changes undergone by atoms and molecules in the course of a chemical reaction; many are not able to justify explicitly the breaking of inter‐molecular bonds and to interpret the breaking of intramolecular bonds in terms of reorganization of atoms, the target level of understanding in the curriculum from the end of Grade 9. However, it is also suggested that some of the specific characteristics identified here are linked to the ordering and language used in the French curriculum, and such cultural idiosyncrasies may offer useful insights into both problematic and valuable aspects of science pedagogy. 相似文献

Children’s stereotypes about scientists have been postulated to affect student science identity and interest in science. Findings from prior studies using “Draw a Scientist Test” methods suggest that students see scientists as largely white, often unattractive, men; one consequence may be that girls and minority students feel a science career is “not like me”. However, a major shortcoming in prior research is that scholars have asked children to draw only scientists, thus making interpretations of earlier research findings ambiguous. We added other professionals to compare how 616 drawings of teachers, scientists, and veterinarians by 206 elementary school children varied by student gender, ethnicity, and grade. Students made clear distinctions: drawing teachers as most attractive and largely female, and scientists as most often male and least attractive. Aspects of the drawings suggest that scientists do have an “image problem” among children. However, large sex differences in the drawings and often‐unrecognizable gender figures in boys’ pictures lead us to question use of the “Draw a Scientist Test” as a projective test among young children. 相似文献

We have developed a teaching‐learning sequence (TLS) on friction based on a preliminary study involving three dimensions: an analysis of didactic research on the topic, an overview of usual approaches, and a critical analysis of the subject, considered also in its historical development. We found that mostly the usual presentations do not take into account the complexity of friction as it emerges from scientific research, may reinforce some inaccurate students’ conceptions, and favour a limited vision of friction phenomena. The TLS we propose begins by considering a wide range of friction phenomena to favour an initial motivation and a broader view of the topic and then develops a path of interrelated observations, experiments, and theoretical aspects. It proposes the use of structural models, involving visual representations and stimulating intuition, aimed at helping students build mental models of friction mechanisms. To facilitate the reproducibility in school contexts, the sequence is designed as an open source structure, with a core of contents, conceptual correlations and methodological choices, and a cloud of elements that can be re‐designed by teachers. The sequence has been tested in teacher education and in upper secondary school, and has shown positive results in overcoming student difficulties and stimulating richer reasoning based on the structural models we suggested. The proposed path has modified the teachers’ view of the topic, producing a motivation to change their traditional presentations. The open structure of the sequence has facilitated its implementation by teachers in school in coherence with the rationale of the proposal. 相似文献

Graduate teaching assistants (GTAs) are gaining increasing responsibility for the instruction of undergraduate science students, yet little is known about their beliefs about science pedagogy or subsequent classroom practices. This study looked at six GTAs who were primary instructors in an introductory biology laboratory course. Teaching assistants taught a lesson about the potential social, health, and environmental impacts of genetically modified crops. Through classroom observations and in‐depth interviews, the researchers examined how instructors chose to frame their lessons and what GTAs perceived as important for students to know about this particular socioscientific issue (SSI). Results showed a disconnect between the relatively mature conceptualizations of effective SSI instruction that emerged during interviews and classroom practice. 相似文献

Science, technology, engineering, and mathematics (STEM) fields, important in today’s world, are underrepresented by students with disabilities. Students with visual impairments, although cognitively similar to sighted peers, face challenges as STEM subjects are often taught using visuals. They need alternative forms of access such as enlarged or audio‐converted text, tactile graphics, and involvement in hands‐on science. This project focused on increasing teacher awareness of and providing funds for the purchase of supplemental adaptive resources, supplies, and equipment. We examined attitude and instructional changes across the year of the programme in 15 science and mathematics teachers educating students with visual impairments. Positive changes were noted from pretest to posttest in student and teacher perspectives, and in teacher attitudes towards students with disabilities in STEM classes. Teachers also provided insights into their challenges and successes through a reflective narrative. Several adolescent students resisted accommodations to avoid appearing conspicuous to peers. Teachers implemented three strategies to address this: providing the adaptations to all students in the class; convincing the student of the need for adaptation; and involving the class in understanding and accepting the student’s impairment. A variety of teacher‐created adaptations for various science and mathematics labs are reported. Another finding was many adaptations provided for the student with visual impairment benefitted the entire class. This study supports the claim that given knowledgeable, supportive teachers, and with appropriate accommodations such as tactile or auditory materials, students with visual impairments can be as successful and engaged as other students in science and mathematics. 相似文献

This paper examines the use and role of the term ‘hypothesis’ in science teacher education as described by teacher students. Data were collected through focus group interviews conducted at seven occasions with 32 students from six well‐known Swedish universities. The theoretical framework is a sociocultural and pragmatist perspective on language and learning, introducing the notion of pivot terms to operationalise language use as a habit and mediated action. We describe three different customs of using the term ‘hypothesis’ within four cultural institutions that can be said to constitute science teacher education in Sweden. Students were found to habitually use the term hypothesis as meaning a guess about an outcome. This is contrasted to the function of this term in scientific research as a tentative explanation. We also found differences in how this term was used between the pure science courses given by the science departments of universities and science education courses taken only by teacher students. Findings also included further support for school students hypothesis fear reported in an earlier study. It is discussed how these findings can obstruct learning and teaching about the nature of scientific inquiry. Constructivist theories of learning are suggested as a possible origin of these problems. The findings are also related to curricular reform and development. 相似文献

In the Least Economically Developed Countries (LEDCs), School Based Teacher Development (SBTD) is sometimes advocated as a potential mechanism for improving the classroom practices experienced by millions of children in a complete school system, as quickly as possible. Robust evidence is required for approaches to be implemented with some confidence by Government development agencies, such as the UK Department for International Development (DFID). SBTD has a long history stemming from ideas of school-based curriculum development, which underlay the ideas on teacher-as-researcher, and is typically advocated in the developed world based on a view of the teacher as a professional. How might such notions play out, and to what effect, in LEDC contexts? This article examines the issues at stake in introducing SBTD in LEDCs, by examining: the nature of the evidence for various forms of teacher development, the nature of SBTD in particular and the evidence for its effectiveness. The latter issues will be illustrated through examination of English in Action (EIA, www.eiabd.com), a large-scale SBTD programme for primary and secondary English language (EL) teachers serving government schools across Bangladesh. 相似文献

This paper presents the initial findings of a long-term study to examine whether the introduction of compulsory school science for pupils in UK schools in 1991 is effective in raising the general level of scientific literacy. The use of the term 'scientific literacy' in the literature is considered and a definition of the term as it is applied in this study is offered. The scientific literacy level of two groups of initial teacher training studentswith contrasting experiences of school sciencewas compared. Students completed a simple science test that had been originally written for 11-year-old children. The average test score of students who had experienced compulsory school science from the ages of 11 to 16 was found to be significantly higher (p = 0.014) than that of students for whom school science was optional at secondary level. The study also highlights specific areas of conceptual difficulty in basic science experienced by almost all of the students tested. Test questions relating to the circulatory system, light and sound produced very low scores from almost all students, regardless of their science background. The paper considers the implications of these findings for science teachers and policymakers in both the primary and secondary sectors. 相似文献

While Western educators caution against contrived collegiality in the midst of enthusiasm for peer coaching as a form of teacher development, Hong Kong educators are struggling to detach discussion and observation of classroom teaching from staff appraisal. The challenges for this task are twofold: to secure a niche for peer coaching in the practice of staff development, and to ward off contrived collegiality in the course. Using an action research paradigm, the present project attempted to meet these challenges in two schools. As a joint work between various parties, the present project had to negotiate its way cautiously to achieve genuine collaboration and avoid imposition from the administrators and outsiders to the front-line teachers. During the course, innovative strategies were taken to cope with various difficulties, including time constraints, teachers' psychological pressure, and the possibility of contrived collegiality and implementation partnership. The evaluation of the project showed that the teachers generally accepted peer coaching and found it helpful to their professional development. The experience in the two schools indicated that true collaboration might emerge from organizationally induced collegiality under certain conditions. 相似文献

Background: In the last decade, much research attention has been paid to notions of leadership and the professional identity of school. It is widely agreed that school principals play a very important role in school improvement; international reports point to ‘school leadership’ as a key factor in education quality, and recent studies suggest that the leadership identity of principals is critical for achieving effective leadership in schools worldwide.Purpose: The purpose of this study was to conduct a thematic exploration of the literature relating to school principals and leadership identity.Design and methods: A scoping review was carried out. Two major databases were searched for papers published on this topic in the last decade. Once we had established an overview of research on this subject, we conducted a thematic analysis to identify the topical focus of research.Results: We found that the literature reflected an increasing and intensified interest in the topic of school leadership as the decade progressed. Furthermore, a range of emerging subtopics was identified. These included the relationship between school culture and professional identity in school principals; the influence of ethical and personal factors on the professional development of principals; the dilemmas of balancing education policies and personal experiences; and the relationships between gender identity, racial identity, professional experience/career, training and leadership identity.Conclusions: Several key issues emerged from the studies included in this review, such as the importance of external and internal influences in the construction of the professional identity of school principals. Some of the research suggested that school leaders felt the need to develop a new professional identity. Overall, the study indicates that school leadership and its relationship with school improvement should remain an important focus for educational research investigation. 相似文献
