Connecting the public to concepts in science, technology, engineering, and mathematics (STEM) is an essential for technological advancement and inspiring future scientists, impacting both the communicator and the audience's understanding of scientific topics. Without proper communication of scientific knowledge, acceptance and implementation of new technologies can be hindered. Additionally, increasing public awareness about current scientific issues through STEM engagement permits more informed policy and consumer choices, especially in the field of food science where many new food technologies are met with initial resistance by the consuming public. Here, we describe an event that introduced topics in food science to the nonexpert public, including K‐8th grade participants and their adult caregivers in an informal learning environment. This program consists of six activities that collectively introduce three areas in food science: food chemistry, food microbiology, and process engineering. Protocols are provided for each activity including a materials list (with the option to scale up or down according to event duration, event space allowances, and number of participants), learning objectives and discussion points that are adaptable to different age groups, event spaces, or budgets. Each activity has a participatory component to ensure both audience member and instructor engagement. A program designed for food science communication empowers young scientific minds to better understand complex scientific topics and could inspire them to envision a possible career in STEM fields, with the additional benefit of providing graduate students an exciting medium through which they may practice their science communication skills, potentially benefiting not only their personal academic and professional skills but also broader societal needs.  相似文献

This study examined the nature of science (NOS) views of lower elementary grade level students, including their views of scientists. Participants were 23 third‐grade African American students from two Midwest urban settings. A multiple instrument approach using an open‐ended questionnaire, semi‐structured interviews, a modified version of the traditional Draw‐A‐Scientist Test (DAST), and a simple photo eliciting activity, was employed. The study sought to capture not only the students' views of science and scientists, but also their views of themselves as users and producers of science. The findings suggest that the young African American children in this study hold very distinct and often unique views of what science is and how it operates. Included are traditional stereotypical views of scientists consistent with previous research. Additionally, participants expressed excitement and self‐efficacy in describing their own relationship with science, in and outside of their formal classrooms. Implications for teaching and learning NOS as it relates to young children and children of color are discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 49: 1–37, 2012  相似文献

This study examined elementary and middle school students' images of science and scientists, with an analysis of how those images may be influenced by science textbooks currently in use in Taiwan. A modified Chambers' Draw-a-Scientist Test (DAST) was administered to a total 289 students from grades 1, 3, 5 and 8. Results showed that upper-grade students drew more indicators (i.e., lab coats, eyeglasses, facial features, research and knowledge symbols, and relevant captions) than did lower-grade students. An analysis of individual drawings revealed an increase in sophistication and complexity according to progressively higher grade levels. It was found that students very often drew images strikingly similar to what their science textbook presented. It implicated that our current science textbooks indeed have some degree of influence on students' image of science and scientists.  相似文献

In this paper, we support the validity of drawing from science studies to reshape science education. While true educational reform must involve alternative curricular structures, we stress that we do not propose here either a comprehensive curricular framework or a report on a pilot classroom project, as our research perspective comes from science studies rather than from education. Instead this paper is intended to encourage educators to draw from methodologies used in science studies to further their goals in education research and in classroom teaching. First, we examine theoretical connections and divergences between science studies and theories of education. Secondly, we discuss the benefits of teaching science as a social process and offer some suggestions that can be introduced by classroom teachers into pre-existing science curricula.  相似文献

ABSTRACT

This cross-sectional study explored students’ conceptions of science learning via drawing analysis. A total of 906 Taiwanese students in 4th, 6th, 8th, 10th, and 12th grade were asked to use drawing to illustrate how they conceptualise science learning. Students’ drawings were analysed using a coding checklist to determine the presence or absence of specified attributes. Data analysis showed that the majority of students pictured science learning as school-based, involving certain types of experiment or teacher lecturing. In addition, notable cross-sectional differences were found in the ‘Activity’ and ‘Emotions and attitudes’ categories in students’ drawings. Three major findings were made: (1) lower grade level students conceptualised science learning with a didactic approach, while higher graders might possess a quantitative view of science learning (i.e. how much is learned, not how well it is learned), (2) students’ positive and negative emotions and attitudes toward science learning reversed around middle school, and (3) female students expressed significantly more positive emotions and attitudes than their male counterparts. In conclusion, higher graders’ unfruitful conceptions of science learning warrant educators’ attention. Moreover, further investigation of girls’ more positive emotions and attitudes found in this study is needed.  相似文献

Science laboratory learning has been lauded for decades for its role in fostering positive student attitudes about science and developing students’ interest in science and ability to use equipment. An expanding body of research has demonstrated the significant influence of laboratory environment on student learning. Further research has demonstrated differences in student perceptions based on giftedness. To explore the relationship between giftedness and students’ perceptions of their learning environment, we examined students’ perceptions of their laboratory learning environment in biology courses, including courses designated for high-achieving versus regular-achieving students. In addition, to explore the relationship between students’ perceptions and the extent of their experience with laboratory learning in a particular discipline, we examined students’ perceptions of their laboratory learning environment in first-year biology courses versus elective biology courses that require first-year biology as a prerequisite. We found that students in high-achieving courses had a more favourable perception of all aspects of their learning environment when compared with students in regular courses. In addition, student perceptions of their laboratory appeared to be influenced by the extent of their experience in learning science. Perceptions were consistent amongst regular- and high-achieving students regardless of grade level. In addition, perceptions of students in first year and beyond were consistent regardless of grade level. These findings have critical applications in curriculum development as well as in the classroom. Teachers can use student perceptions of their learning environment to emphasize critical pedagogical approaches and modify other areas that enable enhancement of the science laboratory learning environment.  相似文献

ABSTRACT

In this study, we reviewed 76 journal articles on employing drawing assessment as a research tool in science education. Findings from the systematic review suggest four justifications for using drawing as a type of research tool, including assessment via drawing as (a) an alternative method considering young participants’ verbal or writing abilities, and affective or economic reasons, (b) a unique method that can reveal aspects not easily measured by other methods, (c) a major method that reflects characteristics of science subjects, and (d) a formative assessment to diagnose students’ ideas to benefit their learning. Furthermore, five research trends of studies using drawing as assessment tools are identified, including: (a) students’ conceptions of scientists from the Draw-a-Scientist-Test (DAST) and evolving studies, (b) students’ understanding or mental models of science concepts, (c) participants’ conceptions of science learning or teaching, (d) students’ inquiry abilities and modelling skills via drawing, and (e) technology to support drawing. For each trend, we synthesised and commented on the current findings. A framework conceptualising phases and issues when designing research and instruments employing drawing assessments is proposed. The review provides insights into the design and future direction of research employing drawing assessments in science education.  相似文献

Throughout the United States, various summer science programs for precollege students are conducted with an aim toward increasing the involvement of young people in science. Most of these programs are perceived as successful by teachers and scientists because they involve students in hands-on science activities, improve their scientific skills and confidence, and allow them the opportunity to use science to answer questions and solve problems. The work described here involves a detailed assessment of a summer National Science Foundation (NSF) Young Scholars Program, which was carried out over 2 summers. Student participants were entering 9th and 10th grade. The data used for this assessment included journals kept by teaching assistants, questionnaires administered to the participants and parents, and interviews with the participants. Analysis revealed that students perceived program success differently from teachers and program organizers. Their perception of the success of a program is directly related to whether or not their individual research project met its goals, regardless of other project activities. Designing projects that have a high likelihood of success from this perspective can be complex, but this work identified six variables that must be incorporated appropriately into the design of a project to ensure its success: (1) extent of project structure and who structures the project, faculty or student; (2) project relevance; (3) project flexibility; (4) project background research; (5) tangible results; and (6) project introduction.  相似文献

It has been observed that many young children like making marks on paper and that they enjoy the activity. It is also known that children’s drawings are vehicles for expression and communication. Therefore, it would be logical and reasonable for teachers to incorporate children’s drawings into building science concepts. To demonstrate how drawings are utilized to help a child to acquire a science concept, the article first presents a vignette of an interaction between an adult and a 5-year-old boy, focusing on the science concept of the physical characteristics of a spider. It is then followed by several analytical explanations of how drawings build children’s understandings. Not only are the introduced strategies useful for one-on-one interactive communication, but also applicable to a small group of young children. The article ends with the specifics of how these strategies were applied to a group of four children in their acquisition of the science concept of the water cycle.  相似文献

This study investigated high school students’ conceptions of technology-assisted science learning via drawing analysis, and explored how students with different degrees of computer experience and science learning self-efficacy may show different conceptions via their drawings. The participants included 335 senior high school students in Taiwan (179 male and 156 female). All of them were asked by guiding questions to make two drawings to represent their conceptions of technology-assisted science learning in actual and ideal contexts, respectively. Their background information including computer experience and science learning self-efficacy were obtained using self-reported questionnaires. Through drawing analysis, seven categories of conceptions of technology-assisted science learning were identified, including types of technology, location of learning, types of learning activities, content of learning, participants of learning activities, affordance of learning technology, and effects of learning technology. The results further revealed that the students’ conceptions of actual and ideal technology-assisted science learning significantly differed in some sub-categories of all categories except the category of participants of learning activities. Moreover, students’ computer experience and science learning self-efficacy may link to different conceptions of technology-assisted science learning. Future research and directions are also discussed.

The use of unifying themes that span the various branches of science is recommended to enhance curricular coherence in science instruction. Conceptions of spatial scale are one such unifying theme. This research explored the accuracy of spatial scale conceptions of science phenomena across a spectrum of 215 participants: fifth grade, seventh grade, ninth grade, twelfth grade, and doctoral students in science. Conceptions spanning sizes from one nanometer to one billion meters were investigated through use of written assessments and individual interviews. Results showed that accuracy of conceptions at small scale were not symmetrical with respect to conceptions at large scale. Large scale accuracy tended to decline in a smooth, uniform fashion as the scale increased, whereas small scale accuracy displayed a discontinuity at the microscopic level. To conceptually interact with scales far removed from human scale, experts used strategies of mentally jumping to a new scale‐world. Experts tended not to transition smoothly between the differently scaled worlds but rather to make a discontinuous leap, maintaining abstract linkages between the worlds via mathematics. Implications of these findings for curriculum development and classroom instruction are discussed. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 1061–1085, 2006  相似文献

Current studies reveal that meta-level variables are very important in learning; however, little research has been devoted to the role of metaconceptual and meta-affective variables on student achievement. With the aim of filling this gap in the literature, the present study investigated the relationship between metavariables (metaconceptual awareness, metaconceptual regulation, affective awareness, and affective regulation) and science achievement with the mediating effect of science self-efficacy through structural equation modeling. A total of 576 eighth grade students participated in the study. Results indicated that science self-efficacy partially mediated the relationship that metaconceptual regulation and affective regulation have with science achievement. In other words, students who monitor and evaluate their existing conceptions and follow, control, and adapt their emotions are likely to have high science self-efficacy and then high science achievement. In addition, metaconceptual awareness, metaconceptual regulation, and affective regulation positively predicted science self-efficacy, which was itself a positive predictor of science achievement. The findings imply that metavariables are essential components of science achievement via self-efficacy.  相似文献

One of the issues identified in a recent study of science teaching and learning in Fiji's primary and secondary schools was the problems faced by students in coping with scientific terminology, and in expressing ideas in their own words (Muralidhar, 1989). In this paper, some examples from the study are used to illustrate the extent of the problem and to discuss the implications for teaching and learning science. It is argued that the quality of communication is an important factor in promoting the understanding of science, especially when the main sources of information for the majority of students are the textbook and the teacher. Specializations: Science teacher education, curriculum in action, problem solving, curriculum evaluation, naturalistic research.  相似文献

In response to Crockett's analysis of the relation of science and the instruction of students with learning disabilities, we discuss reasons why teaching in special education is infrequently affected by science and research, and we propose a model of naturalistic decision making and make recommendations for bridging the gap between research and practice based on that model. By building an extensive experiential base in using effective practices, we propose that teachers can become experts at the craft of applying research-based methods. Bringing science into the classroom by basing craft on research in this way represents one promising alternative for improving outcomes for students with and without learning disabilities.  相似文献

In consideration of the potential of drawing and writing as assessment and learning tools, we explored how early primary students used these modes to communicate their science understandings. The context for this study was a curricular unit that incorporated multiple modes of representation in both the presentation of information and production of student understanding with a focus on the structure and function of carnivorous plants (CPs). Two science teacher educators and two first-grade teachers in the United States co-planned and co-taught a multimodal science unit on CP structure and function that included multiple representations of Venus flytraps (VFTs): physical specimens, photographs, videos, text, and discussions. Pre- and post-assessment student drawings and writings were statistically compared to note significant changes, and pre- and post-assessment writings were qualitatively analysed to note themes in student ideas. Results indicate that students increased their knowledge of VFT structure and function and synthesised information from multiple modes. While students included more structures of the VFT in their drawings, they were better able to describe the functions of structures in their writings. These results suggest the benefits for student learning and assessment of having early primary students represent their science understandings in multiple modes.  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

Religious beliefs in science classrooms   总被引：3，自引：0，他引：3  
The question of the relationship between science and religion assumes importance for many secondary school students of science, especially but not exclusively for those in Christian schools. Science as presented in many school classrooms is not as objective and value free as it might seem on first examination, nor does it represent adequately the range of beliefs about science held by students and teachers. This paper reports part of a larger research study into beliefs about science and religion held by students, teachers and clergy in a Lutheran secondary school. Results indicate that participants in the study was the relationship between science and religious belief in ways unforeseen and unappreciated by traditional school science programs. The stories of selected participants are told and they frame a discussion of implications of the study for science teaching.  相似文献

This study explores the impact of a cryogenics‐based enrichment programme, which involves demonstrations that use liquid nitrogen, on attitudes towards science and the learning of science concepts. The findings presented in this paper are based on a sample of 214 fifth‐grade students from two schools in Singapore who had their enrichment lesson in a subzero‐temperature science centre. Overall, the students viewed science as more enjoyable and acquired more interest in wanting to pursue science careers after experiencing the cryogenics‐based enrichment programme, but no remarkable and conclusive change was detected in their perceptions of the social implications of science. Significant knowledge gains were also detected among the participants. The programme did not have any differential impact on students of either gender and from two learning streams, both cognitively and affectively.  相似文献

Abstract

The purpose of this study is to investigate students’ mental models of the marine environment and to further examine how these models are related to their perceptions of marine problems. One hundred twenty-eight ninth grade students from a large harbor city in southern Taiwan completed a survey including a drawing activity and a set of two-tier questions. Using a four-factor rubric to analyze student drawings, we found that students’ mental models of the marine environment are generally partial and unconnected. In particular, the human component was often missing in the drawing. Students showed a strong awareness of marine problems; however, their awareness is focused on waste pollution. Moreover, correlation analysis showed that students’ mental models are associated with the scope of the perceived problems.  相似文献

This article focuses on the impact of a professional play that we developed in order to introduce elementary learners of an urban school to the research of a scientist working at a local university. The play was written in a way that might increase student understandings of the nature of science, scientific inquiry, the identity of scientists, and the work that scientists do. We collected pre-and post-play questionnaire responses and drawings of scientists from third and fourth grade students who attended the play. We also interviewed five of the ten teachers whose students attended the play. Findings indicated that most of these teachers felt strongly that their students had learned about scientific inquiry, the identity of scientists, and the work that scientists do as a result of attending the play. However, less than half of the student questionnaires and drawings of scientists indicated such growth as a result of the play. That being said, numerous students were able to tell us what they learned from the play and many questionnaire responses and drawings indicated such learning. Implications for partnerships between schools and university faculty from various disciplines in order to develop potentially impactful plays that portray authentic scientific research are discussed.  相似文献
