Systems thinking is an important skill in science and engineering education. Our study objectives were (1) to create the basis for a systems thinking language common to both science education and engineering education, and (2) to apply this language to assess science and engineering teachers’ systems thinking. We administered two assignments to teacher teams: first, modelling the same adapted scientific text, and second, modelling a synthesis of peer-reviewed articles in science and engineering education, with teams selecting a topic from a list and summarising them. We assessed those models using a rubric for systems thinking we had developed based on our literature review of this topic. We found high interrater reliability and validated the rubric’s theoretical construct for the system aspects of function, structure and behaviour. We found differences in scores between the assignments in favour of the second assignment, for two attributes of systems thinking: ‘expected outcome/intended purpose’ and ‘main object and its sub-objects’. We explain the first attribute difference as stemming from the modellers’ domain expertise as science or engineering teachers, rather than as scientists or engineers, and the second attribute difference – from the larger amount of information available for modelling the articles synthesis assignment. The theoretical contribution of this study lies in the definition of the systems thinking construct as a first step in establishing a common language for the science education and engineering education communities. The study's methodological contribution lies in the rubric we developed and validated, which can be used for assessing the systems thinking of teachers and potentially also of undergraduate students. 相似文献

This paper outlines research undertaken during a study visit to The Gambia (2008) and our thinking about the value of this, and other such visits for education students. The qualitative methodology made use of interviews and reflective journals. We argue that such visits may have the power to transform peoples’ values and, drawing on literature on identity and positioning, we tentatively suggest some possible explanations for such transformative processes. This kind of experience is thought to be of considerable potential benefit to beginning teachers and the paper indicates some of these benefits, with illustrations drawn from interview data. 相似文献

In an effort to identify policies that foster an institutional “culture of teaching,” or encourage use of effective pedagogies,
this study uses data from 5,612 faculty members at 45 institutions to examine connections between institutional policies and
faculty members’ perceptions and practices related to teaching and learning. A series of multi-level models suggests that
academic policy variables have small and generally insignificant relationships to such faculty perceptions or practices. Instead,
conventional institutional characteristics, such as selectivity and Carnegie classification, appear to be more influential
factors. 相似文献

This paper explores the function of the visual syntax of images in Greek primary school textbooks. By using a model for the formal analysis of the visual material, which will allow us to disclose the mechanisms through which meanings are manifested, our aim is to investigate the discursive transition relating to the view of nature and the human-nature relationship between two series of natural science textbooks. The model is applied to a total of 635 pictures; 434 coming from the old series of textbooks introduced in the early 1980s and 201 from the new introduced in 2006. The results show that a) no differences in the codes of the visual representation of nature or human-nature relationship were recorded between the two series of textbooks, b) the environmental rhetoric mediated by the pictorial material of the textbooks appears closer to its lay counterpart than to scientific rhetoric, c) both series of textbooks favor a viewer-picture relation which diverges from the epistemological (subject/object) ideas of the romantic worldview and comes closer to the baroque one that depicts the world as non-linear and disconnected, while gives more freedom to the viewer to proceed to subjective interpretations. Thus, we assert that the baroque approach adopted by both series of textbooks does not aim at the initiation of students to the highly conventionalized ways of expression, and ultimately to the formalized and scientific rhetoric. On the contrary, within a constructionist context, the textbooks’ visual mode allows students to equally share power with a quite familiar world. 相似文献

The present article describes the rationale, development and initial evaluation of a framework for enquiry that enabled a team of educational psychologists from four local education authorities to co-research the concept of 'noticing and adjusting' in relation to children's literacy progress. The work is based on reflective practice where psychologists and teachers considered the usefulness of the framework in developing interactive assessment and teaching approaches in the classroom. The collaborative work helped us to focus on teacher practice and innovative thinking rather than child, teacher or resource/environmental deficits. 相似文献

This study examined changes in middle school teachers’ beliefs about inquiry, implementation of inquiry practices, and self-efficacy to teach science through inquiry after participating in a year-long professional development program. The professional development model design was based on Bandura’s (1986) social cognitive theory of learning and literature on effective professional development. Using the Electronic Quality of Inquiry Protocol (EQUIP) before and after the program (Marshall, Smart & Horton, 2010), teachers’ quality of inquiry instruction significantly increased across all 4 EQUIP factors. To assess teachers’ inquiry teaching efficacy, the Teaching Science as Inquiry (TSI; Dira-Smolleck, 2004) instrument was administered 3 times to the teacher participants. Changes between time points of TSI administration were examined for personal self-efficacy and outcome expectancy across 5 essential features of classroom inquiry. Findings for the personal self-efficacy scale showed statistically significant gains from pre-Institute to 1-year follow-up for all 5 inquiry features. Teachers’ outcome expectancy beliefs significantly increased across the program for 3 of the 5 essential features of inquiry. The results indicate the effectiveness of the professional development model at increasing the participants’ inquiry efficacy as well as the quality of their inquiry instruction. Our study provides evidence to support the need to include collaborative practice-teaching and reflection opportunities within professional development models that aim to increase teachers’ use of inquiry-based instructional strategies. 相似文献

A porous silicon (PSi) based microarray has been integrated with a microfluidic system, as a proof of concept device for the optical monitoring of selective label-free DNA-DNA interaction. A 4 × 4 square matrix of PSi one dimensional photonic crystals, each one of 200 μm diameter and spaced by 600 μm, has been sealed by a polydimethylsiloxane (PDMS) channels circuit. The PSi optical microarray elements have been functionalized by DNA single strands after sealing: the microfluidic circuit allows to reduce significantly the biologicals and chemicals consumption, and also the incubation time with respect to a not integrated device. Theoretical calculations, based on finite element method, taking into account molecular interactions, are in good agreement with the experimental results, and the developed numerical model can be used for device optimization. The functionalization process and the interaction between DNA probe and target has been monitored by spectroscopic reflectometry for each PSi element in the microchannels. 相似文献
