Background and purpose : This study details the use of a conceptual framework to analyze prospective teachers’ images of scientists to reveal their context-specific conceptions of scientists. The conceptual framework consists of context-specific conceptions related to positive, stereotypical and negative images of scientists as detailed in the literature on the images, role and work of scientists. Sample, design and method : One hundred and ninety-six drawings of scientists, generated by prospective teachers, were analyzed using the Draw-A-Scientist-Test Checklist (DAST-C), a binary linear regression and the conceptual framework. Results : The results of the binary linear regression analysis revealed a statistically significant difference for two DAST-C elements: ethnicity differences with regard to drawing a scientist who was Caucasian and gender differences for indications of danger. Analysis using the conceptual framework helped to categorize the same drawings into positive, stereotypical, negative and composite images of a scientist. Conclusions : The conceptual framework revealed that drawings were focused on the physical appearance of the scientist, and to a lesser extent on the equipment, location and science-related practices that provided the context of a scientist’s role and work. Implications for teacher educators include the need to understand that there is a need to provide tools, like the conceptual framework used in this study, to help prospective teachers to confront and engage with their multidimensional perspectives of scientists in light of the current trends on perceiving and valuing scientists. In addition, teacher educators need to use the conceptual framework, which yields qualitative perspectives about drawings, together with the DAST-C, which yields quantitative measure for drawings, to help prospective teachers to gain a holistic outlook on their drawings of scientists. 相似文献

This study examined children''s drawings to explain children''s conceptual understanding of plant structure and function. The study explored whether the children''s drawings accurately reflect their conceptual understanding about plants in a manner that can be interpreted by others. Drawing, survey, interview, and observational data were collected from 182 students in grades K and 1 in rural southeastern United States. Results demonstrated the children held a wide range of conceptions concerning plant structure and function. These young children held very simple ideas about plants with respect to both their structure and function. Consistent with the drawings, the interviews presented similar findings. 相似文献

Drawings are often used to obtain an idea of children's conceptions. Doing so takes for granted an unambiguous relation between conceptions and their representations in drawings. This study was undertaken to gain knowledge of the relation between children's conceptions and their representation of these conceptions in drawings. A theory of contextualization was the basis for finding out how children related their contextualization of conceptions in conceptual frameworks to their contextualization of drawings in pictorial convention. Eighteen children were interviewed in a semi‐structured method while they were drawing the Earth. Audio‐recorded interviews, drawings, and notes were analysed to find the cognitive and cultural intentions behind the drawings. Also, even children who demonstrated alternative conceptions of the Earth in the interviews still followed cultural conventions in their drawings. Thus, these alternative conceptions could not be deduced from the drawings. The results indicate that children's drawings can be used to grasp children's conceptions only by considering the meaning the children themselves give to their own drawings. 相似文献

Exploratory factor analysis was used to identify models underlying drawings of the greenhouse effect made by over 200 entering university freshmen. Initial content analysis allowed deconstruction of drawings into salient features, with grouping of these features via factor analysis. A resulting 4-factor solution explains 62% of the data variance, suggesting that 4 archetype models of the greenhouse effect dominate thinking within this population. Factor scores, indicating the extent to which each student's drawing aligned with representative models, were compared to performance on conceptual understanding and attitudes measures, demographics, and non-cognitive features of drawings. Student drawings were also compared to drawings made by scientists to ascertain the extent to which models reflect more sophisticated and accurate models. Results indicate that student and scientist drawings share some similarities, most notably the presence of some features of the most sophisticated non-scientific model held among the study population. Prior knowledge, prior attitudes, gender, and non-cognitive components are also predictive of an individual student's model. This work presents a new technique for analyzing drawings, with general implications for the use of drawings in investigating student conceptions. 相似文献

A total of 1098 students, from second graders to university chemistry students, drew representations of highly magnified views of air at 1.0 atmosphere of pressure and at 0.5 atmosphere of pressure. The drawings were classified and the authors inferred from them a relatively limited number of preconceptions of the nature of gases. Several major trends occurred in the frequencies of these inferred preconceptions held at different grade levels. The majority of the drawings that were not in fairly close agreement with atomic theory seemed to reflect one or more of the following misconceptions: (a) air is a continuous (nonparticulate) substance, (b) gas behavior is similar to liquid behavior, and (c) there is relatively little space between gas particles. The number of drawings that gave evidence of particulate views ranged from 8% for Grades 2–4 to 85% for university chemistry students. However, 33% of the university students' drawings showed highly packed particles, and only 37% showed particles in an approximately correct geometrical distribution. The authors suggest a technique for promoting conceptual change among students who possess alternative views of the nature of gases. 相似文献

This study described the conceptual understandings of 50 early childhood (Pre‐K‐3) preservice teachers about standards‐based lunar concepts before and after inquiry‐based instruction utilizing educational technology. The instructional intervention integrated the planetarium software Starry Night Backyard™ with instruction on moon phases from Physics by Inquiry by McDermott (1996). Data sources included drawings, interviews, and a lunar shapes card sort. Videotapes of participants' interviews were used along with the drawings and card sorting responses during data analysis. The various data were analyzed via a constant comparative method in order to produce profiles of each participant's pre‐ and postinstruction conceptual understandings of moon phases. Results indicated that before instruction none of the participants understood the cause of moon phases, and none were able to draw both scientific moon shapes and sequences. After the instruction with technology integration, most participants (82%) held a scientific understanding of the cause of moon phases and were able to draw scientific shapes and sequences (80%). The results of this study demonstrate that a well‐designed computer simulation used within a conceptual change model of instruction can be very effective in promoting scientific understandings. © 2007 Wiley Periodicals, Inc.

With the emergence of the new technologies, twenty-first-century learning involves the application of new media in educational environments. Digital storytelling (DST) is a method that blends traditional storytelling with new technologies. This study was designed to compare the conceptual understanding of preschool students in DST classrooms with children in traditional storytelling classrooms. A pre-test, post-test control group design was used. Data were collected from 149 preschool children using pre- and post-test surveys and students’ drawings. The findings indicate that DST improved the preschoolers’ conceptual understanding of the course content more than traditional storytelling. 相似文献

This study investigated the effect of non-traditional guided inquiry instruction on middle school students’ conceptual understandings
of lunar concepts. Multiple data sources were used to describe participants’ conceptions of lunar phases and their cause,
including drawings, interviews, and a lunar shapes card sort. The data were analyzed via a constant comparative method to
produce profiles of each participant’s conceptual understandings and nonparametric tests also were used. Results revealed
very positive performance for observable moon phases and patterns of change, as well as the cause of moon phases. Results
indicated that significantly more participants shifted from drawing nonscientific shapes on the pretest to drawing scientific
shapes on the post-test. Results for the drawings of moon phase sequences were similar in that significantly more participants
shifted from drawing alternative waxing and waning sequences on the pretest to drawing scientific sequences on the post-test.
Also, significantly more participants shifted from alternative understanding of the cause of the moon phases on the pretest
to scientific understanding on the post-test. Implications of these findings and recommendations for further research are
provided. 相似文献

The present paper was part of a larger project, which investigated the process of knowledge acquisition in Christian religion. The concept of God in particular is a core construct in any religion and it has been involved in a number of changes in the history of religions. Some of those changes were observed in the children's constructions of the house that God lives in. Among children's drawings we found changes which imply, in terms of Thagard (1992) not only belief revision, but also a conceptual change. However, hierarchy reinterpretation, in which the concept of God changes from the part of the cosmos to the creator (ontologically different from the creatures) we did not observe among the primary school children. The development of the different hierarchies we constructed on the basis of children's drawings seems to follow the developmental changes, which took place in the history of Greek religions. Finally, there were some implications for Religious Education. 相似文献

Distinctiveness effects in children's (5-, 7-, and 11-year-olds) false memory illusions were examined using visual materials. In Experiment 1, developmental trends (increasing false memories with age) were obtained using Deese-Roediger-McDermott lists presented as words and color photographs but not line drawings. In Experiment 2, when items were photographed with heterogeneous colored backgrounds, developmental trends were eliminated relative to words and homogeneous backgrounds. Experiments 3 and 4 examined whether the conceptual nature of the background mattered and presented items in neutral (color only), theme-congruent, or theme-incongruent contexts. The results showed that the nature of the context did not matter, only whether the backgrounds were homogeneous or heterogeneous. Apparently, children use distinctive perceptual, but not conceptual, features to attenuate false memory illusions. 相似文献
