The concepts of randomness and variation are pervasive in science. The purpose of this study was to document how post-secondary life science students explain randomness and variation, infer relationships between their explanations, and ability to describe and identify appropriate and inappropriate variation, and determine if students can identify sources of variation. An instrument designed to test statistical concepts was administered to 282 college students from three universities, ranging from introductory non-science majors to science graduate students. Students readily distinguished between causes of variation. A naïve no-pattern concept of randomness persisted from first-year non-science majors to senior-level science majors, contributing to incorrect responses on the variation instrument. Students’ expressions of randomness were better predictors of performance on the variation instrument than their expressions of variation. It is argued that inclusion of everyday language uses of randomness in instruction can bridge the gap between vernacular and scientific uses of this term. 相似文献

A goal of most environmental education is to motivate students toward environmentally friendly behaviour change. This article describes a study that elucidates how such motivation can be fostered in the classroom. It compared students’ development of environmental motivation in a conventional post-secondary environmental biology course and a similar course guided by self-determination theory (SDT). Students in the SDT-guided course experienced less amotivation after the course than students in the comparison section. This article presents a preliminary empirical examination of the utility of SDT in a formal environmental education setting. 相似文献

Discussions about the what, the when and the how of teaching and learning in schools deal in German-speaking countries with the term Lehrplan, while English-speaking countries discuss similar topics with the term curriculum. Yet, these two terms are not just exchangeable terms in two different languages, but imply also two different styles of reasoning or two different modes of thinking. By the examples of a Lehrplan designed by Georg Kerschensteiner for the Munich school in 1899 and two different Lehrpläne for the elementary school in the Swiss canton of Zurich, one from 1905, the other just currently being implemented, the paper discusses the question, what is being studied, when the notion of Lehrplan defines the research focus. Against this backdrop the paper askes in a concluding chapter, what can be gained by guiding research by the Anglo-Saxon notion and tradition of curriculum history and if and how comparative research is possible, regarding the tight coupling of language and concepts. 相似文献

Component content management (CCM) enables organizations to create, manage, and deliver content as small components rather than entire documents. As CCM methodologies, processes, and technologies are increasingly adopted, CCM is reshaping technical communication (TC), the roles of technical communicators, and the skills they need for career success. This article reviews scholarly and trade publications that describe changes in roles and needed skills in CCM environments and identifies implications of these changes for TC education. 相似文献

This article lays out some of the key issues driving organizations' increasing interest in enterprise content management (ECM). It then problematizes both the rhetoric that technology developers are using to sell ECM technologies to business leaders and the assumptions on which business leaders are basing critical technology implementation decisions. Finally, it argues why technical communicators must take action—through direct participation in the ECM discourse—to shift the rhetoric that is structuring the ECM debate and thus shaping the potential of the field of technical communication. 相似文献

One of the most intriguing results concerning chronopsychological effects at school is the worse school performance in evening‐oriented adolescents. The study intends to correlate affective state with chronotype. Therefore, we carried out a field study in adolescents in a natural setting (in school) and assessed their actual affective state during the very first lesson at school (8:00 a.m.). A total of 97 pupils (60 boys and 37 girls; mean age 13.14 ± SD 1.84; range 10–17 years) from class Grades 5, 6, 8, 9, and 10 participated in this study. We used the Composite Scale of Morningness (CSM) to assess morningness and the Adjective Checklist for Children (EWL40‐KJ) to assess mood. Morningness was positively associated with relaxation, good mood, and activation, and negatively related to bad mood, anger, and deactivation. No significant relationship was found related to excitation, aggression, anxiety, and depressiveness. Concerning the two general dimensions, CSM scores were positively related to positive mood and negatively to negative mood. 相似文献

There is a perception in British universities and art colleges that art students are not very good at writing, that they don't want to write, and furthermore, that writing gets in the way of the real business of making art. These perceptions are reinforced in much of the literature that has been produced about, and in support of, undergraduate art education in the last few decades. This paper will examine the tensions, both historical and contemporary, between academic practices (such as the academic essay, the dissertation) and fine art studio practices. This translative gap both produces, and perpetuates, a set of binaries: visual/textual, art/literature, words/images, Studio/Art History, making/writing. The net result of which is a resistance to writing from many Art students in Higher Education. I will outline subject specific multidisciplinary strategies used with undergraduate and postgraduate students to harness, and develop, this resistance as both transformational and inventive. 相似文献

Ecosystem modeling is a critically important tool for environmental scientists, yet is rarely taught in undergraduate and graduate classrooms. To address this gap, we developed a teaching module that exposes students to a suite of modeling skills and tools (including computer programming, numerical simulation modeling, and distributed computing) that students apply to study how lakes around the globe are experiencing the effects of climate change. In the module, students develop hypotheses about the effects of different climate scenarios on lakes and then test their hypotheses using hundreds of model simulations. We taught the module in a 4-hour workshop and found that participation in the module significantly increased both undergraduate and graduate students’ understanding about climate change effects on lakes. Moreover, participation in the module also significantly increased students’ perceived experience level in using different software, technologies, and modeling tools. By embedding modeling in an environmental science context, non-computer science students were able to successfully use and master technologies that they had previously never been exposed to. Overall, our findings suggest that modeling is a powerful tool for catalyzing student learning on the effects of climate change. 相似文献

PurposeThe present study aimed to examine the link between physical activity (PA) and life satisfaction in a large international study of adolescents. We also aimed to test whether overweight and underweight perceptions act as mediators and whether age and sex acted as moderators.MethodsFor this purpose, we analyzed data from the Health Behavior in School-aged Children study, which comprises 727,865 observations from 44 nations at 4 measurement occasions.ResultsMultilevel analyses revealed a positive link between PA and life satisfaction. In addition, underweight and overweight perceptions mediated the effect of PA on life satisfaction. We further found that age and sex acted as moderators. In older adolescents, stronger effects were found in the links between PA and life satisfaction, PA and overweight perception, and both weight perceptions and life satisfaction. In addition, in female adolescents, the link between overweight perception and life satisfaction was stronger. Conversely, the links between PA and both weight perceptions were stronger for boys.ConclusionThe results suggest that weight perception explains part of the relationship between PA and life satisfaction in adolescents and that these effects vary as a function of age and sex. 相似文献
