Studying children's knowledge base of one-sided levers as force amplifiers     

Miriam Leuchter  Britta Naber 《科学教学研究杂志》2019,56(1):91-112

Attention to core concepts in science and engineering in early education has grown recently, and understanding levers as force amplifiers can be recognized as one of these. Previous studies focused on two-sided levers and do not provide sufficient information about children's knowledge of levers as force amplifiers, nor about their learning and its support from an education perspective. It is important to consider load distance and force distance separately, as may be done in one-sided levers, to understand children's knowledge of levers as “simple machines” thoroughly. Moreover, children's zone of proximal development and the possibilities to foster their knowledge should be explored to understand important features of teaching. We thus directed two studies with 6- to 7-year-old children. In study 1, we conducted a paper-and-pencil test in the context of wheelbarrows (N = 370; age M = 6.62). We investigated whether it is possible to empirically separate the features load, load distance, and force distance as well as to determine their level of difficulty. Our study showed that children's concepts of the three aspects load, load distance, and force distance are fragmented, with children finding it continuously more difficult to judge load, load distance, and force distance correctly. In study 2, we developed a 20-min intervention with a controlled 2 × 2 pre-post follow-up design for exploring the zone of proximal development of 304 6- to 7-year-old children in the domain of one-sided levers as force amplifiers, focusing on force distance and load distance. We implemented a structured learning environment that encouraged the children to manipulate wheelbarrows and supported them with pictures and/or verbal prompts. 6- to 7-year-old children had a higher learning gain when they were exposed to scaffolds that combined pictures and verbal prompts in the posttest as well as in the follow-up test four weeks later compared to the control group.  相似文献   

An examination of the interactions between museum educators and students on a school visit to science museum     

Neta Shaby  Orit Ben-Zvi Assaraf  Tali Tal 《科学教学研究杂志》2019,56(2):211-239

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   

Test-Based Learning: Inconsistent Effects Between Higher- and Lower-Level Test Questions     

Julian Roelle  Detlev Roelle  Kirsten Berthold 《Journal of Experimental Education》2019,87(2):299-313

Providing test questions after an initial study phase is a common instructional technique. In theory, questions that require higher-level (deep) processing should be more beneficial than those that require lower-level (shallow) processing. However, empirical evidence on the matter is inconsistent. To shed light on two potential reasons for these inconsistencies, we conducted an experiment (N = 81) to analyze the role of (a) the share of information to which test questions direct learners and (b) the learning activities performed in the initial study phase with respect to the effects between higher- and lower-level test questions. We found that both the share of focused information and the initial learning activities moderated the effects between higher- and lower-level test questions.  相似文献   

Teaching primary mathematics with challenging tasks: How should lessons be structured?     

James Russo  Sarah Hopkins 《The Journal of educational research》2019,112(1):98-109

Engaging students in a challenging (cognitively demanding) task and launching a mathematics lesson with a task before instruction are two characteristics of a reform-oriented approach to mathematics instruction often considered together. The authors systematically contrasted teaching with challenging tasks using a task-first lesson structure with that of a discussion-first lesson structure to three composite classes of first- and second-grade students (n = 73). Subsequent assessments of mathematical performance revealed that the discussion-first lesson structure was somewhat more efficacious in improving fluency performance but both structures similarly improved problem-solving performance. The findings suggest there is more than one way of incorporating challenging tasks into mathematics lessons to produce sizeable learning gains.  相似文献   

Students' self-efficacy for science in different school systems     

Bat-Shahar Dorfman  David Fortus 《科学教学研究杂志》2019,56(8):1037-1059

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   

Experientially learning how to communicate science effectively: A case study on decoding science     

Monique L. R. Luisi  Shelly Rodgers  Jack C. Schultz 《科学教学研究杂志》2019,56(8):1135-1152

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   

Learning while playing: Children's Forest School experiences in the UK   总被引：1，自引：0，他引：1  

Janine K. Coates  Helena Pimlott-Wilson 《British Educational Research Journal》2019,45(1):21-40

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   

Examining the ethical environment in higher education     

Mary Richardson  Mary Healy 《British Educational Research Journal》2019,45(6):1089-1104

Higher Education Institutions (HEIs) across the world have found themselves faced with new challenges on issues of ethics. Much of this has been centred on issues of assessment: plagiarism, buying essays, sharing/lending of previously passed work and the stealing of marked/returned work of others. Institutions still treat academic misconduct as largely a behavioural difficulty rather than an issue of ethics (or education), suggesting that academia places a far greater emphasis on combating new forms of dishonesty than it does on encouraging ethical habits and a healthy ethical environment. To date, the majority of research in this area has examined these forms of academic misconduct from the point of view of the student and/or the university, with the perspective of academics receiving very limited attention. Our hypothesis is that academics are perhaps best placed to provide the education needed to create and sustain an ethical environment, and we argue that being ‘ethically aware’ is a critical factor in the development of academic competence for all parties. This study adds to existing research in three ways: firstly, by highlighting the importance of an overall framework for an ethical environment within HEIs; secondly, by suggesting an ecological model of key parties (the university, students and academics) with responsibility for this environment in assessment; and thirdly, by including new evidence (generated by a survey of academics) to extend our understanding of their views on these issues.  相似文献   

The interplay between self-determined motivation,self-regulated cognitive strategies,and prior achievement in predicting academic performance     

Sara Manganelli  Elisa Cavicchiolo  Luca Mallia  Valeria Biasi  Fabio Lucidi  Fabio Alivernini 《教育心理学》2019,39(4):470-488

The present study examined the interplay between self-determined motivation and the use of cognitive strategies in predicting university students’ academic performance while taking into account the effect of prior achievement. A theory based model was tested using structural equation modeling on a sample of 764 Italian university students. Results showed that prior achievement influenced students’ academic performance and their motivation and use of cognitive strategies. Critical thinking was the only cognitive strategy which proved to have a significant impact on students’ academic performance. Autonomous motivation had an indirect positive impact on academic performance through its influence on the critical thinking strategy. Controlled motivation had a direct negative impact on academic performance. On the whole, our findings suggest that autonomously motivated students tend to achieve better academic performance by using critical thinking, while students who are driven by controlled motivation have lower academic performance.  相似文献
