Learning about circuitry by connecting a battery, light bulb, and wires is a common activity in many science classrooms. In this paper, we expand students’ learning about circuitry with electronic textiles, which use conductive thread instead of wires and sewable LEDs instead of lightbulbs, by integrating programming sensor inputs and light outputs and examining how the two domains interact. We implemented an electronic textiles unit with 23 high school students ages 16–17 years who learned how to craft and code circuits with the LilyPad Arduino, an electronic textile construction kit. Our analyses not only confirm significant increases in students’ understanding of functional circuits but also showcase students’ ability in designing and remixing program code for controlling circuits. In our discussion, we address opportunities and challenges of introducing codeable circuit design for integrating maker activities that include engineering and computing into classrooms.  相似文献

Effects of Web-based Support for the Construction of Competence Maps     

Angela Stoof  Rob L. Martens  Jeroen J. G. van Merriënboer 《Instructional Science》2006,34(3):189-211

Educationalists experience difficulties with the construction of competence maps that describe final attainment levels of educational programs. Web-based support was developed with three supportive aids: A construction kit, a phenomenarium, and an information bank. Each supportive aid was expected to improve perceived process and product quality as well as learning. In a full factorial experiment, 266 educational science students constructed a competence map, whether or not supported by different combinations of the three supportive aids. The availability of the construction kit and the phenomenarium had positive effects on perceived process quality and learning. Furthermore, if there was no phenomenarium with example materials, the absence of the construction kit greatly diminished experienced support (i.e., one aspect of process quality); if a phenomenarium was present, the availability of the construction kit had relatively little effect on perceived support. In general, this study indicates that well-designed Web-based support helps to construct competence maps. in final form: 2 February 2006  相似文献   

Radical Artists & Art Students versus Management & Bureaucracy during the 1970s     

John A. Walker 《The International Journal of Art & Design Education》2001,20(2):230-237

This paper is an account of the impact of Conceptual art and art theory upon art students, studio tutors and managers during the 1970s in certain British art schools. The impact on students resulted in a shift away from the making of physical artefacts to the production of writings and magazines. It also problematised ‘the visual’ and encouraged critiques of art and the art education system. Some tutors responsible for art theory courses were dismissed and some students became politicised and attacked those in charge of art schools and polytechnics. Managers disciplined the students and, in some instances, failed and expelled them. William Furlong and Bruce McLean were two London based artists who responded to the ever‐increasing bureaucracy of art colleges by mounting a parodic performance.  相似文献   

Sustainable assessment for lifelong learning     

Tham T.H. Nguyen  Melanie Walker 《Assessment & Evaluation in Higher Education》2016,41(1):97-111

This paper explores the alignment of assessment practices in universities and lifelong learning as a key process and outcome for expansive student development. It outlines Boud’s approach to assessment, operationalises this to analyse practices in two contrasting national contexts: the sociology departments of the Midlands University in the UK and Nam Du University in Vietnam, and reframes this framework as a guide to improving practices and better-supporting lifelong learning. The paper thus contributes to recent debates about sustainable assessment and how to change assessment to better support students for lifelong learning in different countries. The findings suggest that although more elements were found at Midlands University than Nam Du University, assessment in both cases was an imperfect realisation of this framework. Nonetheless, the paper argues that the framework can offer guidance for changes to align assessment practices with lifelong learning, but to do this it should be adapted to the education context and also expanded to include explicit social commitments to others for expansive lifelong learning.  相似文献

Jurisprudential and Ethical Perspectives on "The Best Interests of Children"     

Keith Walker 《Interchange》1998,29(3):287-308

Justifications of policies must be clearly warranted if educational leaders are to continue to maintain integrity and to sustain the trust of those served. Educators are called upon to mediate many private and public interests, including those pertaining to personal, organizational, professional, and societal values. This work of mediating conflicting values often relates to guarding and/or advocating the interests of children. Leaders must understand what they mean when evoking the potent phrase in the best interests of children. More importantly, they must avoid the temptations of sophistic misuses of the best interests of children notion. What is meant when we say we are deciding in the best interests of children? Each of the political, psychological, pedagogical, philosophical, jurisprudential, and ethical grounds undergirding the concept of the best interests of the child contributes content and meaning to the phrase. While each of these perspectives merits consideration, this article is delimited to an exploration of three interpretations from the field of jurisprudence and four interpretations from the field of ethics.  相似文献

Blood Pressure,Fitness, and Lipid Profiles of Rural Women in the Wellness for Women Project     

Patricia A Hageman  Carol H Pullen  Susan Noble Walker  Linda S Boeckner 《Cardiopulmonary Physical Therapy Journal》2010,21(3):27-34

Purpose: This study examined whether rural women, who had a high prevalence of prehypertension and hypertension upon enrollment in a wellness program, would also have a high prevalence of other cardiovascular disease risk factors such as low fitness and/or dyslipidemia. Methods: Data were analyzed from 225 rural women, ages 50-69, enrolled in a healthy eating and activity clinical trial. Cardiovascular health histories, fitness measures, blood pressure, and fasting blood serum samples were collected following standardized protocols at rural research offices. Chi-square and MANOVA were performed to examine differences in health characteristics, lipids, and fitness across blood pressure categories. Results: Fitness indicators of estimated VO_2max, 1-mile walk time, and resting heart rate differed between the blood pressure groups, with those in the prehypertensive and hypertensive groups having less desirable profiles than those in the normotensive group. Triglyceride levels of 150 mg/dL or greater, were observed in 36%, 32%, and 16.7% of women who had hypertensive, prehypertensive, and normal blood pressures, respectively. Conclusions: The need for routine blood pressure screenings by practitioners is reinforced by finding that rural women screened via PAR-Q and/or physician clearance had a high prevalence of prehypertensive and hypertensive blood pressures, in addition to low fitness and nonoptimal triglycerides. Practitioners need to provide counselling based on results and refer to other providers as appropriate.Key Words: blood pressure, lipids, fitness, rural women  相似文献
