One of the challenges for analysing science classroom discourse is a better understanding of intercontextual relationships in the learning process. In this paper, we used orientations from ethnography in education to organise and propose an analytical metaphor called the hourglass approach. It involves three phases of analysis that correspond to the parts of the hourglass. The first phase involves obtaining a continuous cross section of classroom history and the intersections between sociocultural contexts and the science learning contexts, throughout this track record. The second phase involves discourse analysis of few selected events is the vertex of the hourglass. Finally, in the third phase, the analysis of interactions is focused on intercontextual relationships for the interpretation of science learning opportunities. We illustrate this approach based on interactions during science lessons in a first-grade class. In particular, we discuss, in greater detail, how a meaningful intercontextual element in the participants’ group (i.e. the gender norm), intermingled with the engagement of students in practices from the conceptual, epistemic and social domains of scientific knowledge.
As a result of suggestions from the American Library Association (ALA) the Division of Library and Information Science (DLIS) program at St. John's University implemented an end-of-program electronic portfolio (ePortfolio) requirement. The purpose of this ePortfolio is to provide information on student proficiency in the eight ALA core competencies to our external accrediting agency—the ALA Committee on Accreditation (CoA). This article will discuss how a Library and Information Studies (LIS) faculty member and a New Media and Communications Specialist worked together in developing the ePortfolio as an assessment tool for ALA reaccreditation within an online LIS program. 相似文献
Nowadays, universities tend to promote more learner-centred learning, creating a more interactive and motivational environment for students and teachers. This paper describes an expanded framework to help chemical educators to construct a quiz for solution of chemical exercises in their courses. The novelty of this contribution is that the proposed tool combines a flashcards-based method with knowledge pills. The framework has three levels: definition of problem for a teacher; the quiz; use of the quiz for the student. The tool could provide predefined or automatically generated exercises of chemicals. Students could practise where and whenever they like via the Internet. Theirs answers would be registered automatically by the tool and if the students have doubts about any of the questions, they can see a knowledge pill with a teacher explanation about the solution of the exercise. Moreover, they would be able to check their scores from the tests. Once the flashcards were designed and produced, the opinions of other lecturers and students about them were considered. Both groups considered that the tool could be useful to improve the students’ learning process. For future work, this design will be used with the students and its effectiveness will be analysed. 相似文献
This article identifies how clicker use can support or augment existing principles of good teaching across different disciplines in higher education. While many of these principles will be familiar to instructors, the link between student response system (SRS) use and existing pedagogical methods is still often unclear, even for scholars who are well read in the literature. Functioning as a resource for both novices and instructors who have already incorporated clickers into their courses, this article synthesizes existing literature and offers empirical data from five courses in three disciplines to show how SRSs can be used to support contemporary pedagogical goals. The authors discuss five exemplary practices, providing sample clicker questions along the way, to show how clickers can be used to facilitate active learning in large courses. 相似文献
ResumenSe contrasta la hipótesis de un posible efecto de facilitación mediante la representación previa de unas premisas sobre la competencia lógica de niños de nueve años. Los resultados no permiten confirmar la incidencia de ese efecto cuando la tarea exigida está por encima de la competencia lógica actual de los sujetos. 相似文献
ResumenEn general, se ha mantenido que los niños en edad preescolar recuerdan mejor en tareas de aprendizaje incidental que en las de aprendizaje intencional. En este estudio se ha reexaminado esta cuestión y se ha visto que no existe tal diferencia. Niños de 3 a 5 reconocieron de modo semejante una serie de objetos y dibujos, tanto si se les había advertido previamente que debían recordar como si no. El estudio ha demostrado asimismo, y en concordancia con otros trabajos, que el recuerdo no es independiente del nivel de conocimiento ni de la edad del niño. En virtud de estos resultados se hace una interpretación de la memoria infantil acorde con la teoría de los niveles de procesamiento. 相似文献
Relations were examined between epistemic profiles, metacognition, problem solving, and achievement in the context of learning
in an educational psychology course. Two hundred thirty-one university students completed self-report inventories reflecting
their epistemic profiles and use of metacognitive strategies, and were epistemically profiled as rational, empirical, or both
rational and empirical in their approaches to knowing. From the larger sample, 78 students participated in a problem-solving
session using a think aloud protocol. Results demonstrated that for self-reported metacognitive strategies, students profiled
as both rational and empirical had the highest frequency of metacognitive strategy use compared to students profiled as empirical.
Similarly, during problem solving, students profiled as both rational and empirical had the highest frequency of regulation
of cognition compared to students profiled as empirical or rational. Finally, students profiled as both rational and empirical
attained higher levels of problem-solving achievement compared to students profiled as empirical. 相似文献
