Research in Food Science Education: Measuring Gains in Critical Thinking in Food Science and Human Nutrition Courses: The Cornell Critical Thinking Test,Problem‐Based Learning Activities,and Student Journal Entries     

Wayne T. Iwaoka  Yong Li  Walter Y. Rhee 《Journal of Food Science Education》2010,9(3):68-75

Abstract: The Cornell Critical Thinking Test (CCTT) is one of the many multiple‐choice tests with validated questions that have been reported to measure general critical thinking (CT) ability. One of the IFT Education Standards for undergraduate degrees in Food Science is the emphasis on the development of critical thinking. While this skill is easy to list as a student‐learning objective, measuring gains in CT is relatively difficult. If the majority of the class time is spent discussing and solving ill‐defined problems, then will students become actively and meaningfully involved in their own learning and will there be any gains in CT skills? To measure gains using this format, the CCTT was administered as a pre‐ and posttest to Food Science and Human Nutrition students in an Experimental Foods class taught every fall over an 8 y period (2001–2008). Statistical analysis indicated that in 2 of the years (2002 and 2004), there were significant gains (P values 0.036 and 0.045, respectively) in CT scores. Furthermore, in both years, there were significant gains in the same 2 aspects of CT (deduction and assumption) and not in the other aspects. However, we suggest that completing several take‐home exams with many open‐ended questions, writing detailed laboratory reports, and documenting unsolicited student reflections in journal entries that comment on apparent gains in CT skills may be a better indication of actual gains in CT skills compared to the actual CCTT test scores.  相似文献

Coherent Knowledge Structures of Physics Represented as Concept Networks in Teacher Education     

Ismo T. Koponen  Maija Pehkonen 《Science & Education》2010,19(3):259-282

A characteristic feature of scientific knowledge is the high degree of coherence and connectedness of its conceptual structure. This notion is also behind the widely accepted instructional method of representing the concepts as networks. We suggest here that notions of explanatory coherence and deductive coherence naturally connect the structure of knowledge to the processes which are important in constructing the concept networks. Of these processes, experimental method and modelling are shown to be closely connected with explanatory and deductive coherence, respectively. From this viewpoint, we compare here how experts and novices represent their physics knowledge in the form of concept networks, and show that significant differences between experts’ and novices’ quality of knowledge become directly reflected in the structure of the networks. The results also show how concept networks make visible both the structure of knowledge and the methodological procedures, which support its formation.  相似文献

Approaches to teaching in mainstream and separate postsecondary classrooms     

Marschark M  Richardson JT  Sapere P  Sarchet T 《American annals of the deaf》2010,155(4):481-487

The study examined attitudes toward teaching reported by university instructors who normally teach hearing students (with the occasional deaf or hard of hearing student) and by instructors who normally teach deaf and hard of hearing students at the same institution. Overall, a view of instruction as information transmission was associated with a teacher-focused approach to instruction, whereas viewing instruction as a means of promoting conceptual change was associated with a student-focused approach. Instructors in mainstream classrooms were more oriented toward information transmission than conceptual change, whereas instructors experienced in separate classrooms for deaf and hard of hearing students reported seeking to promote conceptual change in students and adopting more student-focused approaches to teaching. These results are consistent with previous findings concerning instructors' approaches to teaching and deaf and hard of hearing students' approaches to learning, and may help explain recent findings regarding student outcomes in separate versus mainstream secondary classrooms.  相似文献   

Curriculum design for inquiry: Preservice elementary teachers' mobilization and adaptation of science curriculum materials     

Cory T. Forbes  Elizabeth A. Davis 《科学教学研究杂志》2010,47(7):820-839

Curriculum materials are crucial tools with which teachers engage students in science as inquiry. In order to use curriculum materials effectively, however, teachers must develop a robust capacity for pedagogical design, or the ability to mobilize a variety of personal and curricular resources to promote student learning. The purpose of this study was to develop a better understanding of the ways in which preservice elementary teachers mobilize and adapt existing science curriculum materials to plan inquiry‐oriented science lessons. Using quantitative methods, we investigated preservice teachers' curriculum design decision‐making and how their decisions influenced the inquiry orientations of their planned science lessons. Findings indicate that preservice elementary teachers were able to accurately assess how inquiry‐based existing curriculum materials are and to adapt them to make them more inquiry‐based. However, the inquiry orientations of their planned lessons were in large part determined by how inquiry‐oriented curriculum materials they used to plan their lessons were to begin with. These findings have important implications for the design of teacher education experiences that foster preservice elementary teachers' pedagogical design capacities for inquiry, as well as the development of inquiry‐based science curriculum materials that support preservice and beginning elementary teachers to engage in effective science teaching practice. © 2009 Wiley Periodicals, Inc.

Supply issues for science academics in Australia: now and in the future     

Daniel Edwards  T. Fred Smith 《Higher Education》2010,60(1):19-32

Australia, like the rest of the developed world, is in the midst of dealing with notable issues related to the age structure of its academic workforce. These issues are widespread and have been articulated in the Australian context most comprehensively by Hugo (2008). This paper investigates issues with demographic change and other key factors related to the desirability of a science or mathematics academic career within Australian universities. It draws on the findings of a research project undertaken in 2008 for the Department of Education, Employment and Workplace Relations. The findings show that while demographic issues are not as dire for science academics compared to the entire sector, issues relating to tenure, workload and retaining young science academics in Australia are a threat to the long-term sustainability of science faculties in Australian universities.  相似文献   

Bases of competence: an instrument for self and institutional assessment     

Iris Berdrow  Frederick T. Evers 《Assessment & Evaluation in Higher Education》2010,35(4):419-434

The Bases of Competence model provides a general framework for learner‐centred skill development and programme‐focused outcomes assessment. Based on previous research, the Bases of Competence model describes 17 skills and four base competencies important to graduates to achieve high performance in the workplace. Taking this work from research to relevant educational application as a tool for student self‐assessment and institutional outcomes assessment is the focus of this paper. Results from a multi‐year, multi‐course assessment initiative indicate that students rate themselves stronger in the foundation base competencies of Communicating and Managing Self, and weaker in more complex competencies of Managing People and Tasks and Mobilising Innovation and Change. Comparisons of skill confidence within each base competence as well as between year, student level, gender and beginning versus end of semester are presented as well. These results are discussed and suggestions made for programme design.  相似文献   

A multifaceted approach to teacher induction   总被引：1，自引：0，他引：1  

Dana L. Bickmore  Steven T. Bickmore 《Teaching and Teacher Education》2010

The purpose of this study was to determine the implementation and effectiveness of the components of two middle school induction programs through the perceptions of three participant groups – new teachers, mentor teachers, and principals. Effectiveness was defined as a systematic processes embedded in a healthy school climate that met new teachers' personal and professional needs. Data indicated that each element of the induction program – principal and new teacher interaction; mentor teachers; collaborative structures; professional development; and new teacher orientation – met different needs of the new teacher. This multifaceted approach appeared to effectively support new teachers.  相似文献
