We have developed and validated a tool for assessing understanding of a selection of fundamental concepts and basic knowledge in undergraduate introductory molecular and cell biology, focusing on areas in which students often have misconceptions. This multiple-choice Introductory Molecular and Cell Biology Assessment (IMCA) instrument is designed for use as a pre- and posttest to measure student learning gains. To develop the assessment, we first worked with faculty to create a set of learning goals that targeted important concepts in the field and seemed likely to be emphasized by most instructors teaching these subjects. We interviewed students using open-ended questions to identify commonly held misconceptions, formulated multiple-choice questions that included these ideas as distracters, and reinterviewed students to establish validity of the instrument. The assessment was then evaluated by 25 biology experts and modified based on their suggestions. The complete revised assessment was administered to more than 1300 students at three institutions. Analysis of statistical parameters including item difficulty, item discrimination, and reliability provides evidence that the IMCA is a valid and reliable instrument with several potential uses in gauging student learning of key concepts in molecular and cell biology. 相似文献

Abstract The aim of this study was to compare optimization and correction procedures for the determination of peak power output during friction-loaded cycle ergometry. Ten male and 10 female sports students each performed five 10-s sprints from a stationary start on a Monark 864 basket-loaded ergometer. Resistive loads of 5.0, 6.5, 8.0, 9.5, and 11.0% body weight were administered in a counterbalanced order, with a recovery period of 10 min between sprints. Peak power was greater and occurred earlier, with less work having been done before the attainment of peak power, when the data were corrected to account for the inertial and frictional characteristics of the ergometer. Corrected peak power was independent of resistive load (P > 0.05), whereas uncorrected peak power varied as a quadratic function of load (P < 0.001). For males and females, optimized peak power (971 ± 122 and 668 ± 37 W) was lower (P < 0.01) than either the highest (1074 ± 111 and 754 ± 56 W respectively) or the mean (1007 ± 125 and 701 ± 45 W respectively) of the five values for corrected peak power. Optimized and mean corrected peak power were highly correlated both in males (r = 0.97, P < 0.001) and females (r = 0.96, P < 0.001). The difference between optimized and mean corrected peak power was 37 ± 30 W in males and 33 ± 14 W in females, of which approximately 15 W was due to the correction for frictional losses. We conclude that corrected peak power is independent of resistive load in males and females. 相似文献

Abstract This article reports on the first two phases of a multiphase science education development project in predominantly Māori
kura (school communities) in the central region of the North Island of Aotearoa New Zealand. The development project in its
entirety employs an action research methodology and by so doing endeavors to support the improvement of science education
delivery in accordance with school community aspirations. The full project (a) establishes the current situation in Year 1–8
science education in the communities; (b) identifies developmental aspirations for stakeholders within the communities and
identifies potential contributors and constraints to these aspirations; (c) implements mechanisms for achieving identified
aspirations; and finally; (d) evaluates the effectiveness of such mechanisms. In its focus on the first two phases, this article
incorporates the analytical lenses of Kaupapa Māori Theory and Bronfenbrenner’s bio-ecological model. It concludes by outlining
some priorities to consider for science education development based on the outcomes of our preliminary discussions.

The application of performance based criteria in the allocation of resources and the targeting of substantial research funds to topics of national priority are two major features of the new research funding climate in Australian higher education. Successful competition for such funds will depend on universities developing and implementing appropriate research management plans and on the overall research performance of their academic staff. This paper reports the views of academic staff from one Australian university on such issues as the determinants of research performance and the importance of individual autonomy in the selection of research topics. One of the main findings is that research activity is highly variable and influenced by a number of factors including, personal characteristics; differences in research styles, methods and strategies both within and between disciplines; and dependence on funding. The findings show that academics firmly believe in freedom of inquiry in the choice of research topic. 相似文献

As supervisors who advocate the transformational potential of research both to generate theory and practical and emancipatory outcomes, we practice participatory action learning and action research (PALAR). This paper offers an illustrative case of how supervision practices based on action learning can foster emancipatory and lifelong learning within a university context that is becoming ever more focused on throughput of students, rather than on the quality of their learning. Conference attendance offers an excellent opportunity for postgraduate students to develop as researchers and lifelong learners, yet anxiety often prevents them from making the most of the learning experience. We explain how we encouraged the development of capabilities in students through a PALAR support programme that assisted postgraduate students prepare for a conference to make overall participation, presenting a paper and subsequent publication a true learning experience. We generated and analysed data from the written reflections of 11 postgraduate students who participated in the programme. The findings suggest that action learning, specifically PALAR, can be used to enable a rich learning experience for postgraduate students attending conferences through fostering relationships, building trust, a supportive environment, collaboration, communication and competence among them. Postgraduate students who experienced our PALAR support programme developed not only skills, knowledge, confidence and deeper appreciation of learning opportunities through conferences, but also understanding of the principles of PALAR that apply not just to the conference context but across all aspects of learning and research and life at large. 相似文献

The use of the interactive whiteboard for creative teaching and learning in literacy and mathematics: a case study 总被引:2,自引:0,他引:2

This paper considers the ways in which the interactive whiteboard may support and enhance pedagogic practice through whole‐class teaching within literacy and numeracy. Data collected from observations of whole‐class lessons, alongside individual interviews and focus group discussions with class teachers and Initial Teacher Education students, has provided opportunities to consider the potential of such technology to facilitate a more creative approach to whole‐class teaching. The data suggests that, in the first instance, the special features of information and communications technology such as interactivity, ‘provisionality,’ speed, capacity and range enhance the delivery and pace of the session. This research seems to indicate that it is the skill and the professional knowledge of the teacher who mediates the interaction, and facilitates the development of pupils' creative responses at the interface of technology, which is critical to the enhancement of the whole‐class teaching and learning processes. 相似文献

In the context of neoliberal and neoconservative educational reforms, student voice work is faced with a number of potential difficulties in creating the conditions, skills and dispositions necessary for student empowerment. One of the key challenges is evaluating whether student voice initiatives are effective, relevant and transformative. Through a systematic literature review of contemporary student voice literature from the past 10 years, the article proposes an evaluative framework to measure the extent to which student voice contributes to socially transformative educational practices in primary and secondary schools This framework suggests that transformative voice work should be dialogic, intergenerational, collective and inclusive, and transgressive. It argues that the interaction of these four themes forms a set of principles or building blocks which collectively underpin transformative student voice work. The purpose of such an evaluative framework is not to provide a normative benchmarking tool, but rather, to serve as a reflective dialogical tool that could guide teachers and students towards genuine transformation of institutional structures and individual practices as well as informing policy makers, practitioners and researchers. 相似文献

The purpose of this study was to explore the role of counselors in providing validation for men of color in community colleges. Through protocol writing, 13 counselors from seven community colleges responded to open-ended questions asking them to reflect and describe strategies they employed when advising and counseling men of color. Thematic analysis using a combination of detailed, selective, and wholistic reading approaches, as described by van Manen (1990), was employed to identify themes reflecting different forms of validation. Findings from this study demonstrate the critical role of community college counselors as validating agents in affirming men of color as being capable of college success, helping them build confidence, affirming them as individuals, and providing opportunities for academic and personal development. Implications for practice are discussed. 相似文献
