In this paper, we describe the Scientific Habits of Mind Survey (SHOMS) developed to explore public, science teachers’, and scientists’ understanding of habits of mind (HoM). The instrument contained 59 items, and captures the seven SHOM identified by Gauld. The SHOM was validated by administration to two cohorts of pre-service science teachers: primary science teachers with little science background or interest (n?=?145), and secondary school science teachers (who also were science graduates) with stronger science knowledge (n?=?145). Face validity was confirmed by the use of a panel of experts and a pilot study employing participants similar in demographics to the intended sample. To confirm convergent and discriminant validity, confirmatory factor analysis and evaluation of the reliability were calculated. Statistical data and other data gathered from interviews suggest that the SHOMS will prove to be a useful tool for educators and researchers who wish to investigate HoM for a variety of participants. 相似文献

This study examines the epistemic beliefs about justification employed by physics undergraduate and graduate students and faculty in the context of solving a standard classical physics problem and a frontier physics problem. Data were collected by a think-aloud problem solving session followed by a semi-structured interview conducted with 50 participants, 10 participants at freshmen, seniors, masters, PhD, and faculty levels. Seven modes of justification were identified and used for exploring the relationships between each justification mode and problem context, and expertise level. The data showed that justification modes were not mutually exclusive and many respondents combined different modes in their responses in both problem contexts. Success on solving the standard classical physics problem was not related to any of the justification modes and was independent of expertise level. The strength of the association across the problem contexts for the authoritative, rational, and empirical justification modes fell in the medium range and for the modeling justification mode fell in the large range of practical significance. Expertise level was not related with the empirical and religious justification modes. The strength of the association between the expertise level and the authoritative, rational, experiential, and relativistic justification modes fell in the medium range, and the modeling justification mode fell in the large range of practical significance. The results provide support for the importance of context for the epistemic beliefs about justification and are discussed in terms of the implications for teaching and learning science. 相似文献

Course instructors across a wide range of disciplines have implemented computer-based learning resources such as online discussion boards. While the benefits of implementing an online discussion board in teaching have been well-documented, investigation into the social aspects of online learning environments is still needed in order to develop a deeper understanding of how group dynamics affect the overall learning experience. Accordingly, this action research project was designed to explore the perceptions of graduate students concerning the use of an online discussion board, focusing on whether the character of the interactions evidenced in the content of the discussion was reflected in the participants’ views of their experiences. The messages posted to the discussion forum were examined via discourse analysis, while the perceptions of the participants were interrogated through self-administered interviews. The results revealed that while positive group dynamics appeared to be prevalent in the discussion, the perceptions of the individual class members did not always agree with this view. In light of the findings, the researcher outlines some possible solutions for creating an online environment that is conducive to learning for members of a discussion forum with disparate levels of experience, as well as some suggestions for further research. 相似文献

The main objective of this qualitative research study is to demonstrate Norwegian and Turkish novice teachers’ reflections on bumpy moments and which strategies they use to cope with the challenges they have faced in practice. The participants of the present study are novice teachers (n = 17) with a maximum of five years’ teaching experience. The logbook and interview were the main data collection tools used to reflect novice teachers’ challenging moments. The data were recorded and transcribed separately in the two countries, and then the categories across the data were identified and the codes compared. The results mainly indicate that the novice teachers in both contexts are learning from their bumpy moments and using their problem-solving skills, based on either their repertoire gained during school practicum or their own strategies developed over time to find solutions to their challenging experiences. 相似文献

This paper reports on the use of a constructivist-based pedagogy to enhance understanding of some features of solution chemistry.
Pre-service science teacher trainees' prior knowledge about the dissolution of salts and sugar in water were elicited by the
use of a simple diagnostic tool. The test revealed widespread alternative conceptions. These evaluation data were used to
produce two segments of ‘conceptual change text’: concise summaries that present alternative and scientific conceptualizations
for the concepts under study. The texts were administered to 21 pre-service elementary trainee teachers whose understandings
of number of conceptions were subsequently re-evaluated employing a pre-test post-test approach in which their answers and
reasons for their answers were solicited. The findings suggest that these pre-service elementary trainees' alternative conceptions
are changed to become more in accord with the scientific view, with more participants providing correct answers along with
correct reasons than before the intervention. This work suggests that the use of conceptual change text may provide a simple
and cost and resource-effective way to aid conceptual understanding for the dissolution of ionic solids in water including
the effect of solute surface on the dissolution process. 相似文献

As discussed by John Rawls, in a well-ordered society, a public political culture’s wide educational role bears the primary responsibility for developing reasonable individuals for the stability of a politically liberal society. Rawlsian scholars have also focused on the stability and enhancement of developed liberal democratic societies by means of those societies’ education systems. In this sense, one thing that is common to Rawlsian scholars’ and Rawls’s own understanding of the role of education appears to be a concern over the stability of a politically liberal society since it is highly dependent on the character of its citizens. Also, it is usually believed that a politically liberal account of education can be implemented in a developed politically liberal society. In contrast, this study discusses the possibility of implementing a politically liberal account of education in a developing liberal society that may become a developed liberal democracy under an overlapping consensus. 相似文献

This study reports on student teachers' views of portfolios as a learning tool when they are combined with a weekly test conducted at the end of each lesson to help student teachers self‐evaluate. Student teachers' written reflections during the process provided data for the study. Analysis of the data showed that a majority of student teachers initially felt that compiling a portfolio would be time‐consuming and an extra burden added to their already busy schedule. However, later on they all found that the process was a useful learning experience. Moreover, the portfolio process – especially combining self‐reflection with weekly tests – encouraged students to study regularly, increased retention and made learning more enjoyable. Suggestions for the successful portfolio implementation include the following: guiding students both at the beginning of and during the process, providing continuous and prompt feedback during the process and making self‐reflection – especially guided by reflection prompts – an essential part of the process. 相似文献

Taking a test generally improves the retention of the material tested. This is a phenomenon commonly referred to as testing effect. The present research investigated whether two-tier diagnostic tests promoted student teachers’ conceptual understanding of variables in conducting scientific experiments, which is a scientific process skill. In this study, 97 preservice science teachers were divided into three groups. All three groups took a physics laboratory course during the fall term in which they learned about variables in the course. Each group was engaged in a different learning activity after the physics laboratory course: taking a two-tier diagnostic test, taking a multiple choice test, or studying a lecture summary. The narratives of the participants before and after the learning activities were transcribed into a format of flow maps to assess their conceptual understanding of variables. The results revealed that the two-tier diagnostic test is an effective tool in promoting conceptual understanding of complex concepts about variables in conducting scientific experiments. 相似文献
