This paper describes a newly adapted instrument for measuring novice-to-expert-like perceptions about biology: the Colorado Learning Attitudes about Science Survey for Biology (CLASS-Bio). Consisting of 31 Likert-scale statements, CLASS-Bio probes a range of perceptions that vary between experts and novices, including enjoyment of the discipline, propensity to make connections to the real world, recognition of conceptual connections underlying knowledge, and problem-solving strategies. CLASS-Bio has been tested for response validity with both undergraduate students and experts (biology PhDs), allowing student responses to be directly compared with a consensus expert response. Use of CLASS-Bio to date suggests that introductory biology courses have the same challenges as introductory physics and chemistry courses: namely, students shift toward more novice-like perceptions following instruction. However, students in upper-division biology courses do not show the same novice-like shifts. CLASS-Bio can also be paired with other assessments to: 1) examine how student perceptions impact learning and conceptual understanding of biology, and 2) assess and evaluate how pedagogical techniques help students develop both expertise in problem solving and an expert-like appreciation of the nature of biology. 相似文献

First‐year architecture students are expected to utilise visuospatial abilities to generate/construct, retain, rotate and manipulate space mentally and physically through physical and digital representations. This study of 57 female and 23 male participants was conducted to investigate first‐year architecture students’ visuospatial abilities by means of the Beck Depression Inventory, Logical Reasoning Test and Judgment of Line Orientation (JLO) test. Participants’ sexes, cognitive development level, depression scale scores, university entrance exam results, vision disorders, physical competences, art training prior to university and error types were the study’s main parameters. The results showed that academic scores of the participants both to enrol in the program and complete the first‐year studio did not correlate with their JLO scores. Nondepressed participants performed better in JLO. Error analyses demonstrated that there is a concentration on certain items according to the test stimulus line positions, especially in females. Those who reported limited physical and visual competency made more mistakes in the same items. The study concludes that sex, depression, and individual differences in physical and visual competency, and art training, are significant variables for visuospatial performance. Judging visuospatial parameters through spatial design exercises is different from having proper methods and instruments to assess the achievements of the students regarding those abilities in architectural design education. It is important to map students’ visuospatial abilities individually from a developmental perspective. There is a strong need to develop 4D psychometric instrument to assess visuospatial abilities. 相似文献

Recent European research has revealed growth in the number of administrators and professionals across different sections of universities—a long established trend in US universities. We build on this research by investigating the factors associated with variation in the proportion of administrators across 761 Higher Education Institutions (HEIs) in 11 European countries. We argue that the enactment of expanded and diversified missions of HE is one of the main factors nurturing universities’ profesional and administrative bodies. Our findings support such an assertion; regardless of geographical and institutional differences, HEIs with high levels of “entrepreneurialism” (e.g. in service provision and external engagement) are characterized by a larger proportion of administrative staff. However, we find no empirical support for arguments citing structural pressures and demands on HEIs due to higher student enrolments, budget cuts or deregulation as engines driving such change. Instead, our results point towards, as argued by neo-institutionalists, the diffusion of formal organization as a model of institutional identity and purpose, which is especially prevalent at high levels of external connectedness. 相似文献

This study had two purposes: to explore the components of the pedagogical content knowledge (PCK) of an experienced elementary science teacher and to reveal the presumed interactions among these components. A naturalistic inquiry was conducted as a single case study in which in-depth qualitative data were gathered through semi-structured interview questions. After the theory-based and data-driven analysis of the qualitative data, the verbal communication was quantitated into numerical data for the enumerative analysis. The results revealed that the teacher’s knowledge of students’ understanding and difficulties, knowledge of the elementary science curriculum and knowledge of instructional strategies and representations were found to be mostly intersected PCK components, whereas orientations towards teaching science and knowledge of assessment in science had limited connections to the other components. Further discussions and context-based suggestions are given regarding professional development programmes. 相似文献

This study presents an exploration of the belief changes of prospective teachers (PTs) through social co-constructivist teaching. The future presumed in-class teaching orientations of the PTs were also estimated by metaphor analysis. A case study was conducted to monitor the belief changes of the PTs and estimate their probable in-class practices. The participants were six PTs involved in a certification in education programme. The data were gathered from the following different sources; interviews, written reflections and metaphor explanations. The data that were analysed interpretatively and specific parts of the analysed data were subjected to quantification. The PTs held considerably conventional and idealistic teaching beliefs prior to the implementations. The PTs improved their reasoning and enlarged their conceptualisations regarding teaching and learning after the implementations. Five types of teaching belief typologies displaying inherently sophisticated nature of the beliefs were extracted. Some of the PTs appeared to have promise in terms of implementing more learner-centred teaching; however, others preserved their traditional teaching practical orientations. It was considered that changes in teaching beliefs may have motivational and attitudinal dimensions. Finally, capturing the metaphors of the PTs regarding teaching and learning appeared to provide more realistic insights into the estimated in-class practical orientations. 相似文献

We have designed, developed, and validated a 17-question Meiosis Concept Inventory (Meiosis CI) to diagnose student misconceptions on meiosis, which is a fundamental concept in genetics. We targeted large introductory biology and genetics courses and used published methodology for question development, which included the validation of questions by student interviews (n = 28), in-class testing of the questions by students (n = 193), and expert (n = 8) consensus on the correct answers. Our item analysis showed that the questions’ difficulty and discrimination indices were in agreement with published recommended standards and discriminated effectively between high- and low-scoring students. We foresee other institutions using the Meiosis CI as both a diagnostic tool and an instrument to assess teaching effectiveness and student progress, and invite instructors to visit http://q4b.biology.ubc.ca for more information. 相似文献

This is among the first longitudinal studies to report student attitudes across 4 yr of a university program. We found that the attitudes of students in biology become significantly more expert-like from the first year to the fourth year of the program, that is, there was a significant positive shift in students’ overall percent favorable scores from 64.5 to 72%, as opposed to the expert response, which averaged 90%. There was a significant positive shift for the real world connection category (78–85%), the enjoyment (personal interest) category (74–82%), and the conceptual connections/memorization category (66–74%). Moreover, there was a significant correlation between students’ overall percent favorable scores and performance (cumulative grade point average) at the end, but not at the beginning, of the fourth year, with high-performing students having significantly more expert-like attitudes than low-performing students. The correlation between percent favorable score and performance was the strongest for the problem solving: synthesis and application category, in which the highest-performing students finished their fourth year with 90% favorable compared with 35% favorable for the lowest-performing students. A comparison of these results with previously reported results and their implications for teaching are discussed. 相似文献

Interest in student conception of experimentation inspired the development of a fully validated 14-question inventory on experimental design in biology (BEDCI) by following established best practices in concept inventory (CI) design. This CI can be used to diagnose specific examples of non–expert-like thinking in students and to evaluate the success of teaching strategies that target conceptual changes. We used BEDCI to diagnose non–expert-like student thinking in experimental design at the pre- and posttest stage in five courses (total n = 580 students) at a large research university in western Canada. Calculated difficulty and discrimination metrics indicated that BEDCI questions are able to effectively capture learning changes at the undergraduate level. A high correlation (r = 0.84) between responses by students in similar courses and at the same stage of their academic career, also suggests that the test is reliable. Students showed significant positive learning changes by the posttest stage, but some non–expert-like responses were widespread and persistent. BEDCI is a reliable and valid diagnostic tool that can be used in a variety of life sciences disciplines. 相似文献

A vehicle system driven by two independent DC motors is presented here, one of which is used for the right wheel and the other is used for the left wheel. An adaptive compensator using Takagi-Sugeno fuzzy systems is proposed to control the vehicle system. The compensator includes an adaptive model identifier and adaptive controller. An online method is used to adjust the parameters of the identifier model to match the behavior model of the vehicle system. Then, the parameters of the identifier model are employed in a standard parallel-distributed compensator to provide asymptotically stable equilibrium for the closed-loop vehicle drive system, in which the velocity and direction angle of the vehicle are controlled. Results demonstrate that the proposed controller structure is robust to load changes and follows different trajectories very well. 相似文献
