Simon suggested that design, defined broadly, is concerned with any kind of deliberate problem solving, whether it be in fields traditionally associated with design, like architecture and engineering, or fields involving the design of instruction. Since instructional design is a kind ol'skillcd professional behavior, the education of other skilled professionals is examined and suggestions are made for analogous instructional techniques in any field. The question of how instructional designers should be educated is related to the larger question of how to teach people to design in general. 相似文献

The question of how to teach energy has been renewed by recent studies focusing on the learning and teaching progressions for this concept. In this context, one question has been, for the most part, overlooked: how should energy be defined throughout schooling? This paper addresses this question in three steps. We first identify and discuss two main approaches in physics concerning the definition of energy, one claiming there is no satisfactory definition and taking conservation as a fundamental property, and the other based on Rankine’s definition of energy as the capacity of a system to produce changes. We then present a study concerning how energy is actually defined throughout schooling in the case of France by analyzing national programs, physics textbooks, and the answers of teachers to a questionnaire. This study brings to light a consistency problem in the way energy is defined across school years: in primary school, an adapted version of Rankine’s definition is introduced and conservation is ignored; in high school, conservation is introduced and Rankine’s definition is ignored. Finally, we address this consistency problem by discussing possible teaching progressions. We argue in favor of the use of Rankine’s definition throughout schooling: at primary school, it is a possible substitute to students’ erroneous conceptions; at secondary school, it might help students become aware of the unifying role of energy and thereby overcome the compartmentalization problem. 相似文献

ABSTRACT Many educational policymakers consider attendance as a tool to induce learning. Researchers also agree that attendance has a positive effect on learning; however, there are few empirical studies that measure the nature and significance of that effect. The authors analyzed the effect of class attendance on academic performance and evaluated the existence and importance of a minimum attendance requirement. Using student data from a sample of public primary schools in Chile, and considering for endogeneity and sample selection bias, they found two important results. First, attendance had a relevant and statistically significant effect on educational performance. Second, the existence of a threshold was identified, but educational performance did not continue to decrease after a certain number of absences, which seems to contradict policies that have a minimum attendance requirement. 相似文献
