Today, science is a major part of western culture. Discussions about the need for members of the public to access and understand scientific information are therefore well established, citing the importance of such information to responsible citizenship, democracy, socially accountable scientific research and public funding (National Research Council [2009] Learning science in informal environments: People, places, and pursuits. National Academies Press). In recent years there has been an increased interest in investigating not just what visitors to informal environments have learnt after a visit, but also how visitors interact and engage with exhibits during the visit (Davidsson & Jakobsson [2012] Understanding interactions at science centers and museums: Approaching sociocultural perspectives. Rotterdam: Sense Publishers). Within the field of school visits to science museums, however, interactions between students and museum educators (MEs) remain relatively unexplored. In our study of such school visits, we are mainly interested in the interactions that take place between three agents—the students, the museum educator and the physical setting of the exhibit. Using moment-to-moment fine grain analysis of multiple interactions allowed us to identify recurring patterns between students and the museum educators around exhibits, and to examine the MEs’ mediational role during the interactions, and the practices they employ to engage students with exhibits. Our study revealed that most interactions between MEs and students consist of technical explanations of how to operate the exhibits. The interactions that do move past this stage often include two main practices, which the MEs use to promote students’ engagement with the exhibits: physical instruction and engaging the students emotionally. Understanding what is actually happening in the learning process that occurs during students’ interactions with exhibits can help museum educators and exhibit designers improve the experiences of students on school visits. 相似文献

Although widely touted as important, there is little evidence regarding the influence of teaching experience on elementary teachers' science subject matter knowledge (SMK). To better understand this phenomenon, we administered an assessment of science topics taught in the fifth and sixth grades to 169 preservice teachers, 231 fifth-grade teachers, and 208 sixth-grade teachers. We then compared the mean scores of teachers at different stages in the career cycle using one-way and two-way ANOVA and explored the relationship between SMK scores and years of teaching experience using regression analysis. Findings indicate that (i) being assigned to a specific grade level had an impact on teachers' SMK for topics included in the grade level, (ii) teachers' SMK scores were lower later in their careers for both science topics they had never taught and for science topics they were responsible for teaching, and (iii) results differed for fifth and sixth grades. This study adds to the existing literature through the examination of a large sample of elementary teachers, with teachers of varying years of experience, while focusing on the science topics these teachers are responsible for teaching. The results of this study provide strong evidence that (i) years of experience teaching specific science topics is associated with the development of teachers' knowledge of these topics, and (ii) teaching experience, what teachers do in the context of their everyday practice, can be an effective means of self-directed learning for teachers. There is also evidence that this influence is not uniform across years of teaching experience or science topics taught. These findings raise important implications about future research into the mechanism of SMK development through teaching experience and teacher grade-level assignments. 相似文献

A comprehensive review of the literature was conducted to identify current practice on teaching science to students with intellectual disability (ID) and/or Autism Spectrum Disorder (ASD) in relation to two review questions—students' science outcomes and students' and teachers' experiences of the interventions. Six databases related to education, psychology, and science were systematically searched. A detailed protocol can be viewed on PROSPERO (registration number: CRD42017057323). Thirty studies were identified that reported on science interventions and 20 on student/teacher experiences of the interventions. The majority of the studies targeted science vocabulary and concepts. Other targets included inquiry skills and comprehension skills. The majority of the interventions used components of systematic instruction (n = 23). Five studies focused on self-directed learning and two on comprehension-based instruction. Students and teachers reported positive experiences of the interventions. The findings suggest that components of systematic instruction in particular might be effective in teaching science content to students with ID and/or ASD. Further research is needed to explore the effectiveness of identified interventions on teaching more complex science skills and with students with severe disabilities. Some limitations related to the search strategy are highlighted. 相似文献

This research examines factors influencing elementary science teacher learning as they participate in professional development with and enactment of educative curricula in comparison with learning following limited professional development and enactment of traditional curricula. Using a randomized cluster design (125 teachers and 2,694 students in 4th—5th grades) that met the What Works Clearinghouse standards without reservations, teacher learning was conceptualized using four outcomes. Data were analyzed using standard single-level multiple regression models and possible mediation models for the teacher outcomes were considered using piecewise multiple regression and path analytic approaches. Treatment group teachers experienced greater increases in content knowledge, views of science inquiry, beliefs about reform-based teaching, and teaching self-efficacy than comparison group teachers. The findings indicate that what teachers learn from the combination of professional development and teaching with educative curriculum varies according to what their knowledge and beliefs are on entering the experience. Surprisingly, high entry-level self-efficacy was associated not only with lower learning gains for the teachers, but also for their students. Finally, teachers' space science learning and that of their students are implicated as mediators of the positive effect of the professional development and educative curriculum enactment on teacher beliefs about reform science teaching. This work refines and extends a theoretical framework of teachers' participatory relationship with curricula. 相似文献

The important role of self-efficacy (SE) in students' motivation, engagement, persistence, and academic achievements has been reconfirmed by ample research, both in general and for STEM disciplines. As most studies focused on traditional school systems, additional research is needed on how science SE develops in different educational environments, which was the goal of this study. Data were collected from 1979 students in Grades 5–9 from 19 traditional, Waldorf, and democratic schools in Israel. Students completed a questionnaire that assessed their science self-efficacy (SSE), general and academic self-efficacy (GASE), and the sources of their SSE: teachers', parents', and peers' social persuasions, vicarious experiences and mastery experiences. Results revealed that SSE and GASE differed in their levels and in the way they changed with grade. These differences, and variations in the roles of the various sources of SSE, appeared to be influenced by the schools' cultures and curricula. Quantitative results are accompanied by verbal illustrative examples from interviews with students and teachers. 相似文献

The need for science communication programs is matched with the need for program evaluation. This case study is an evaluation of the “Decoding Science” program (DSP) [Rodgers et al. (2018). Science Communication, 40(1), 3–32], a science communication training program, and examines key experiential-learning themes [Kolb, D. A. (1984). Experiential learning: Experience as the source of learning and development. Englewood Cliffs, NJ: Prentice-Hall]. Specifically, we discuss the program's emphasis on learning that science communication is a process that (a) is continual, (b) involves conflict resolution, (c) requires adaptation to the world, (d) requires environmental interaction, and leads to (e) knowledge creation. Additionally, we discuss our analysis of student feedback. Results suggest that the DSP successfully utilizes experiential learning to facilitate the learning of science communication techniques and that future evaluations can lead to the development and improvement of science communication training programs. 相似文献

Gendered patterns in mathematics and science interest emerge in early childhood, develop over time, and ultimately reflect advanced course selection in secondary education. During the crucial time adolescents become aware of their strengths and interests and specialize accordingly, they get the opportunity to participate in out-of-school learning programs such as mathematics and science competitions. This raises the question whether mathematics and science competitions contribute to gender equity by equally promoting female and male interests. In this article, we present a systematic review on gender differences and the mechanisms explaining success and failure in mathematics and science competitions. On an international level, we found large gender differences regarding participation in all Olympiads with the exception of the biology Olympiad. In fairs and national Olympiads, overall participation rates were not gendered as such, but females preferred biology topics whereas males preferred physics related topics. Male and female achievement in fairs was comparable, but males clearly outperformed female participants at the Olympiads, with the smallest differences in the biology Olympiad. Variables and theoretical frameworks explaining participation and achievement and the role of gender in mathematics and science competitions are discussed. We suggest that gender stereotypes, through their influence on self-concept and interest, play an important role in the mechanisms resulting in low female participation rates in and beyond mathematics and science competitions (especially in physics and chemistry). The mechanisms we found explaining female representation during a national selection competition might be considered as reflecting those in female mathematics or science careers and could thus serve as food for thought on countering the gender gap in mathematics and science. 相似文献

This article investigated how mathematic anxiety (MA) of Korean middle school students could be reduced by comparing analytically their cognitive neuroscience and questionnaire results. We developed a three-hour Complex Treatment Program (CTP) on quadratic functions for the study. In the summer of 2016, we collected data of the pre and post MA questionnaires by Mathematics Anxiety Scale for Students (MASS), the percent of correct answers (PCA) and reaction time (RT) by E-prime program, and also brain-imaging data of the event related potentials (ERP) by Electroencephalograph (EEG) using computer-based functional F-G model. The result indicated the CTP to be effective with the group with higher math anxiety and the group with higher achievement respectively. The MASS result was verified with the better performance of PCA on type G, which was measured by E-prime program. Some interesting patterns were revealed on brain-imaging data by EEG, indicating more brain activities with the MA groups. 相似文献
