Standard 9 of the National Science Teachers Association Standards for Science Teacher Preparation is designed to ensure that science teacher preparation programs provide preservice science teachers with the knowledge and
skills to understand and successfully engage students in a safe and ethical manner. This standard contains four components
describing science teachers’ legal and ethical responsibilities, appropriate use of instructional materials (chemicals in
particular), emergency procedures and safety equipment, and guidelines for proper use of living organisms in the classroom.
In this article, we describe the requirements of Standard 9 and provide guidance on assessments that can be used to present
evidence for preservice teachers’ competence in each of the four components. 相似文献

Currently, instructional design theorists are generating new enhancements of traditional design models on both macro and micro levels. This paper summarizes the anticipated changes in instructional design models that will result from today's theoretical activity. It addresses issues such as linearity in the design process, enhanced roles of analysis and evaluation, and the new emphasis on learner control and transfer of training. These model enhancements are being influenced by new interpretations of general systems theory and cognitive learning theory, constructivism, chaos theory, and situated cognition. Predicted model changes also reflect the impact of the new technologies, designer decision-making research, and the performance technology and total quality management movements. These and other intellectual forces are likely to produce diverse models for future designers. 相似文献

Maple Syrup Urine Disease is an autosomal recessive disorder caused by a deficiency in the activity of the branched-chain
α-ketoacid dehydrogenase complex. This rare disorder represents one of the causes of acute neonatal illness which results
in devastating disturbances of neurological development. On investigation of 1750 infants with neurological impairment for
inborn errors of amino acid metabolism, 4 neonates with classical maple syrup urine disease were detected. These otherwise
normal neonates presented in the first week after birth with seizures, lethargy and refusal of feeds, hypoglycemia and metabolic
acidosis. The plasma and urine concentrations of the branched-chain amino acids were increased and there was ketoaciduria.
Two of these neonates expired before specific treatment could be instituted. Routine biochemical screening of neonates with
acute illness could unearth many cases of this rare inherited metabolic disease. 相似文献

Rats exposed for 60 sec to a flashing light stimulus following one-trial fear conditioning showed enhanced retention performance relative to controls not exposed to the flashing light. The results of a second experiment demonstrated a time-dependent gradient of the enhancement effect. In view of additional data indicating that the flashing light is not aversive, these results suggest that the presentation of an exteroceptive stimulus can influence memory processing. 相似文献

Hannah Arendt’s work is gaining increasing recognition in educational administration. But less has been written about her as an educator, colleague, and provocateur. Here, I explore the lasting impressions that Arendt had on former students, colleagues, and friends. This exploration is conducted through the lens of Arendtian narrative inquiry. For Arendt, narrative is fundamental to understanding lived experience, not least because stories provide us with a deeper understanding of an individual. She maintains, however, that it is the spectator, not the actor, who is better able to assess the ‘who’ of a person. Because each spectator has a particular viewpoint, I include diverse recollections that gathered together, create a silhouette of the ‘who’ of Hannah Arendt. I use the term ‘silhouette,’ purposefully, since this is not an in-depth portrait. Rather, it is an impressionistic account of the lasting effects she made on others. These lasting impressions serve to reaffirm Arendt’s belief in the value of storytelling as a powerful means of understanding. 相似文献

This is a report of a developmental research study that aimed to construct and validate an instructional design (ID) model
that incorporates the theory and practice of multiple intelligences (MI). The study consisted of three phases. In phase one,
the theoretical foundations of multiple Intelligences and ID were examined to guide the development of such model. In phase
two the model components were determined and an initial model was constructed. In phase three, the model was reviewed and
validated by experts in the field of ID through a three-round Delphi study. The result was a revised and validated Multiple
Intelligences Design Model. This paper presents the decision-making processes and procedures used in model development, and
provides a framework for the internal validation of ID models using expert review procedures. 相似文献
