Using Performance-Based Assessments to Prepare Safe Science Teachers

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   

Maple syrup urine disease: An uncommon cause for neonatal metabolic distress     

Rita Christopher  S. V. Suresh Babu  L. Nirmala  G. R. Rangaswamy  C. P. Narayan  K. Taranath Shetty 《Indian journal of clinical biochemistry : IJCB》1999,14(2):198-206

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

Presentation of a flashing light following one-trial fear conditioning enhances retention     

Rita Y. Emmerson  Terry L. DeVietti 《Learning & behavior》1982,10(3):325-329

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   

Lasting impressions: Hannah Arendt’s educational legacy     

Rita A. Gardiner 《Journal of educational administration and history》2016,48(4):309-323

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

ID model construction and validation: a multiple intelligences case     

Monica W. Tracey  Rita C. Richey 《Educational technology research and development : ETR & D》2007,55(4):369-390

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   

Fighting to Educate Our Own: Teachers of Color,Relational Accountability,and the Struggle for Racial Justice     

Rita Kohli  Marcos Pizarro 《Equity & Excellence in Education》2016,49(1):72-84

Abstract

Research demonstrates that many teachers of Color enter schools committed to challenging injustice, yet often face barriers to accomplishing this goal. This article presents emergent themes from a qualitative study with 218 self-identified, racial justice-oriented teachers of Color. Using Wilson's (2008 Wilson, S. (2008). Research is ceremony: Indigenous research methods. Halifax, Canada: Fernwood. [Google Scholar]) indigenous cultural framework of relationality and relational accountability to analyze our data, we introduce the concept of community-oriented teachers of Color to describe the accountability these teachers have towards students of Color and their communities. We found that despite their connections, insights, and successes with students, hierarchies of ontology (ways of being) and epistemology (ways of knowing) within schools that promote individualism served to isolate and marginalize community-oriented teachers of Color and, thus, limited their ability to advance racial justice.  相似文献   

Using online tools in participatory research with adolescents to promote civic engagement and environmental mobilization: the WaterCircle (WC) project     

Rita Ruivo Marques  Carla Malafaia  Joaquim L. Faria  Isabel Menezes 《Environmental Education Research》2020,26(7):1043-1059

Abstract

The WaterCircle (WC) project was implemented in a school, with young adolescents, to address environmental problems. Framed in a participatory research (PR) approach, this school-and-community based intervention includes the use of online tools through which environmental problems in the community are discussed within and by a group of students. Using a quasi-experimental design, with intervention and control groups, the present study involved 361 young adolescents, in grades 7 to 9, from a public school in the northern region of Portugal. Mixed methods were used for data collection and analysis, namely based on questionnaires administered in the pre- and post-test moments, as well as on students’ discourses produced in the classroom during planned activities. Statistically significant changes on self-efficacy were found for the experimental group, suggesting that the intervention program has the potential to raise young people’s empowerment regarding environmental issues. The WC program seems to foster students’ awareness of the socio-political dimensions of environmental problems, since they were able to identify different actors in the community who should be involved in the proposed solutions. Longer-term intervention is required to foster the impact of the PR on the students’ experience.  相似文献   

Exploring marine biodiversity through inquiry with primary school students: a successful journey?     

Luísa Jesus-Leibovitz  Ana Margarida Baioa  Rita Borges 《Education 3-13》2017,45(4):437-449

In this work, we present a marine ecology inquiry-based activity, implemented with 164 primary school students. The main goal was to evaluate the activity's impact on students’ understanding about biodiversity and scientific procedures. We also aimed to analyse the potential use of personal meaning maps (PMMs) to assess the impact of the activity on students’ ideas about the topics explored. The results revealed that fieldwork and the exploration of real data were the aspects most emphasised by all intervenient. Finally, the PMMs proved to be a good tool to evaluate the impact of activities developed outside classroom, with primary school levels.  相似文献
