Understanding the influences upon curriculum formation is an ongoing challenge for adult educators. This discussion describes one approach to curriculum analysis—the aspirational myth—based on the notion that instructors and learners co‐construct an idealized identity representing the end point of learning. The aspirational myth is described with reference to an empirical case study of a training programme, and implications for teaching and research discussed. 相似文献

Abstract This study examined the use of ARCS-based, motivational mass e-mail messages designed to improve the motivation and retention of students enrolled in an online, entry-level, undergraduate computer applications course. Data from the Course Interest Survey, based on Keller's ARCS model, were gathered and analyzed for two online groups (one treatment and one control) and compared with a face-to-face class for differences in attention, relevance, confidence, satisfaction, and overall motivation. Based on the analysis, this article argues that simple, cost-effective, and easy-to-design mass e-mail messages show potential for addressing some of the motivational needs and retention concerns of online students. 相似文献

A variety of causes are responsible for a lack in promoting movement in German nursing homes. In this regard, research on resources holds the promise of a lasting capacity to act and should therefore be understood as a paradigm of gerontology of sports. The purpose of this paper is to make a contribution to theoretically and conceptually based approaches for operationalizing resources that promote motor abilities. Methodologically, different instruments are demonstrated that are able to assess the theoretical constructs “movement acitivity” and “influencing factors” as a basis for the subsequent analysis. Finally, a model that identifies resources is presented. It focuses on different personal and environmental factors as well as their interdependencies influencing the movement activity. The model analyzes resources and barriers to everyday movements. In this way, fundamental theoretical points of reference for research activity are shown. 相似文献

Students in introductory biology courses frequently have misconceptions regarding natural selection. In this paper, we describe six activities that biology instructors can use to teach undergraduate students in introductory biology courses how natural selection causes evolution. These activities begin with a lesson introducing students to natural selection and also include discussions on sexual selection, molecular evolution, evolution of complex traits, and the evolution of behavior. The set of six topics gives students the opportunity to see how natural selection operates in a variety of contexts. Pre- and postinstruction testing showed students’ understanding of natural selection increased substantially after completing this series of learning activities. Testing throughout this unit showed steadily increasing student understanding, and surveys indicated students enjoyed the activities. 相似文献

Many students do not recognize that individual organisms within populations vary, and this may make it difficult for them to recognize the essential role variation plays in natural selection. Also, many students have weak scientific reasoning skills, and this makes it difficult for them to recognize misconceptions they might have. This paper describes a 2-h laboratory for college students that introduces them to genetic diversity and gives them practice using hypothetico-deductive reasoning. In brief, the lab presents students with DNA sequences from Africans, Europeans, and Asians, and asks students to determine whether people from each continent qualify as distinct "races." Comparison of the DNA sequences shows that people on each continent are not more similar to one another than to people on other continents, and therefore do not qualify as distinct races. Ninety-four percent of our students reported that the laboratory was interesting, and 79% reported that it was a valuable learning experience. We developed and used a survey to measure the extent to which students recognized variation and its significance within populations and showed that the lab increased student awareness of variation. We also showed that the lab improved the ability of students to construct hypothetico-deductive arguments. 相似文献

Previous research has suggested that adding active learning to traditional college science lectures substantially improves student learning. However, this research predominantly studied courses taught by science education researchers, who are likely to have exceptional teaching expertise. The present study investigated introductory biology courses randomly selected from a list of prominent colleges and universities to include instructors representing a broader population. We examined the relationship between active learning and student learning in the subject area of natural selection. We found no association between student learning gains and the use of active-learning instruction. Although active learning has the potential to substantially improve student learning, this research suggests that active learning, as used by typical college biology instructors, is not associated with greater learning gains. We contend that most instructors lack the rich and nuanced understanding of teaching and learning that science education researchers have developed. Therefore, active learning as designed and implemented by typical college biology instructors may superficially resemble active learning used by education researchers, but lacks the constructivist elements necessary for improving learning. 相似文献

We present a multiple-choice test, the Montana State University Formal Reasoning Test (FORT), to assess college students' scientific reasoning ability. The test defines scientific reasoning to be equivalent to formal operational reasoning. It contains 20 questions divided evenly among five types of problems: control of variables, hypothesis testing, correlational reasoning, proportional reasoning, and probability. The test development process included the drafting and psychometric analysis of 23 instruments related to formal operational reasoning. These instruments were administered to almost 10,000 students enrolled in introductory science courses at American universities. Questions with high discrimination were identified and assembled into an instrument that was intended to measure the reasoning ability of students across the entire spectrum of abilities in college science courses. We present four types of validity evidence for the FORT. (a) The test has a one-dimensional psychometric structure consistent with its design. (b) Test scores in an introductory biology course had an empirical reliability of 0.82. (c) Student interviews confirmed responses to the FORT were accurate indications of student thinking. (d) A regression analysis of student learning in an introductory biology course showed that scores on the FORT predicted how well students learned one of the most challenging concepts in biology, natural selection. 相似文献
