Introducing technology education: Using teachers' questions as a platform for professional development     

Dr Sarah J. Stein  Cambell J. McRobbie  Ian S. Ginns 《Research in Science Education》1999,29(4):501-514

This paper explores the issues and concems identified by a small group of teachers implementing technology ideas using the national document,A Statement on Technology for Australian Schools (Curriculum Corporation, 1994a), represented in four key questions they posed as a result of reflection upon their existing ideas and practices, early in the study. These same issues and concerns framed their later experiences as the study progressed. The case study of one of the teachers is used, to illustrate how the teachers implemented technology education working from their own perspectives and tackling issues and concerns that made sense to them. By reviewing the teachers' own questions about technology implementation, it is becoming, clear that what may be important for professional development in technology education is related to the questions that the teachers themselves are asking about their own, beliefs and practices.  相似文献

Imitation jumps in ski jumping: Technical execution and relationship to performance level

ABSTRACT

Imitation jumps are frequently used in training for ski jumping. Yet, the dynamics of these jumps differ considerably. Thus, the relevance of imitation jumps for ski jumping performance is not elucidated. The aim of this study was to investigate the relationship between the technical execution of imitation jumps and ski jumping performance level. We compared the imitation jumps of 11 ski jumpers of different performance levels using a Spearman correlation transform of time traces of the kinetics (measured using force cells and motion capture) of imitation jumps. The kinetic aspects that were related to performance centred on the moment arm of ground reaction force to the centre of mass before the onset of the push-off, angular momentum early in push-off, thigh angle during the main period of push-off and vertical velocity towards the end of push-off. We propose that the thigh angle may be a key element allowing high development of linear momentum while preparing for appropriate aerodynamic position. Furthermore, the findings suggest that the kinetic development prior to (and during) push-off is more important than the kinematic end state at take-off.  相似文献   

Effects of prior social experience on agonistic responding by Siamese fighting fish (Betta splendens)     

Nancy Woodard Cain  Reid Anderson  Lori Stein  Cynthia Jessen 《Learning & behavior》1980,8(3):491-496

The role of prior social experience in maleBetta agonistic behavior was investigated in two experiments. Fish were either paired with an opponent until dominance was established naturally (Experiment 1) or given prior combat experience with a known aggressive or nonaggressive opponent (Experiment 2). The effects of prior social experience were then observed both in additional paired encounters and in some noncombat agonistic situations. The paired-encounter data indicate thatBetta attack aggressive opponents more than nonaggressive ones and rarely attack opponents once they have submitted. In contrast to attacking, these fish do not show a significant decrease in displays once their opponent has submitted, nor do they display differentially to aggressive and nonaggressive opponents. The noncombat agonistic-situation data indicate that prior social experience affects both the preference of fish for viewing other conspecifics and the waning of display behaviors. These results suggest that submissive and nonaggressive behaviors can inhibit attacks but not displays byBetta, and they emphasize the necessity of controlling for prior social experience when studying aggressive behavior.  相似文献   

Demonstrator influence on observer diet preference: Effects of simple exposure and the presence of a demonstrator     

Bennett G. Galef  Deborah J. Kennett  Moni Stein 《Learning & behavior》1985,13(1):25-30

Previous studies in our laboratory have demonstrated that a naive rat (an observer), after interacting briefly with a previously fed conspecific (a demonstrator), will exhibit an enhanced preference for the diet its demonstrator had been fed. The present studies were undertaken to determine whether demonstrator-induced alterations in observer diet preference were the result of simple exposure of observers to diet-identifying cues emitted by demonstrators during the period of demonstrator-observer interaction. Our results indicated that observer experience of diet-related cues in the stimulus context provided by the presence of a demonstrator was sufficient to enhance observer preference for a diet, whereas simple exposure to that diet was not. We concluded that demonstrator influence on observer diet preferences was not the consequence of simple exposure of observers to demonstrator-emitted cues reflecting demonstrators’ diet.  相似文献   

Impact of federal intervention on higher education     

Dr. Ronald H. Stein 《Research in higher education》1979,10(1):71-82

One of the most serious crises currently facing institutions of higher education is federal intervention. The level which this crisis has reached is attested to by the fact that the presidents of three leading universities (Yale, Harvard, and Cornell) have in the past two years presented major reports addressed exclusively to this concern.The purpose of this article is to assess the impact of recent federal legislation and regulations on higher education. The author articulates the precepts posited in defense of such federal intervention, some of which are: financial contributions, social injustice, moral responsibility, student unrest, etc. The general costs of complying with federal laws and regulations are enumerated. In addition, the article considers the impact of a number of recent federal laws and regulations, including: Health Professions Educational Assistance Act of 1976; Copyright Law of 1976; Affirmative Action and Equal Opportunity; and Section 504 of the Rehabilitation Act of 1973. The author explores the steps that have recently been undertaken to reduce costs of complying with federal regulations and suggests additional solutions to this problem. The article concludes with a prognosis for what higher education can anticipate from the federal government and how higher education best protects its interests.Presented at the Annual Forum of the Association for Institutional Research, Houston, Texas, May 1978.  相似文献   

Sleep disturbances in adolescents with symptoms of attention-deficit/hyperactivity disorder     

Stein D  Pat-Horenczyk R  Blank S  Dagan Y  Barak Y  Gumpel TP 《Journal of learning disabilities》2002,35(3):268-275

We evaluated 32 nonmedicated male adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD) in childhood, 35 male adolescents similarly diagnosed who were receiving methylphenidate (MPH), and 77 control boys. Both ADHD groups completed self-report questionnaires assessing sleep disturbances; weekday and holiday sleep duration; and symptoms of ADHD, anxiety, and depression. Parents and teachers rated the severity of the participants' ADHD. The control group completed self-report questionnaires assessing sleep disturbances. We found that nonmedicated participants and controls did not differ in the severity of sleep disturbance. In contrast, the medicated participants demonstrated a significantly greater severity of sleep disturbance compared with the nonmedicated participants and reported elevated levels of symptoms of ADHD, anxiety, and depression. Specific analyses showed that depressive symptoms contributed significantly to the degree of sleep disturbance when controlling for ADHD diagnosis and MPH treatment. These findings suggest that among adolescents with ADHD symptoms, the severity of symptoms of depression may contribute to the degree of sleep disturbance in addition to the effect of their primary disorder and MPH treatment.  相似文献   

A model for using a concept inventory as a tool for students' assessment and faculty professional development

This essay describes how the use of a concept inventory has enhanced professional development and curriculum reform efforts of a faculty teaching community. The Host Pathogen Interactions (HPI) teaching team is composed of research and teaching faculty with expertise in HPI who share the goal of improving the learning experience of students in nine linked undergraduate microbiology courses. To support evidence-based curriculum reform, we administered our HPI Concept Inventory as a pre- and postsurvey to approximately 400 students each year since 2006. The resulting data include student scores as well as their open-ended explanations for distractor choices. The data have enabled us to address curriculum reform goals of 1) reconciling student learning with our expectations, 2) correlating student learning with background variables, 3) understanding student learning across institutions, 4) measuring the effect of teaching techniques on student learning, and 5) demonstrating how our courses collectively form a learning progression. The analysis of the concept inventory data has anchored and deepened the team's discussions of student learning. Reading and discussing students' responses revealed the gap between our understanding and the students' understanding. We provide evidence to support the concept inventory as a tool for assessing student understanding of HPI concepts and faculty development.  相似文献   

Re-thinking America's Teacher Education Programs     

Les Stein  Alex Stein 《Clearing house (Menasha, Wis.)》2016,89(6):191-196

More than ever before, our nation needs teachers who are not only motivated to teach but who are also properly educated, trained, and prepared for the many challenges that are facing our nation's K-12 public schools. The education departments and schools at our colleges and universities cannot continue to do business as usual—they need to adjust their teacher preparation programs to effectively support the changing times, and to provide our future teachers with a realistic and rigorous education. There is little or no disagreement among educators, social scientists, or anyone else for that matter, that great schools are the product of great teachers. It makes sense, therefore, to create a world-class teacher education and training program.  相似文献   

ADHD,parent perspectives and parent–teacher relationships: grounds for conflict          下载免费PDF全文

Ruth Gwernan‐Jones  Darren A. Moore  Ruth Garside  Michelle Richardson  Jo Thompson‐Coon  Morwenna Rogers  Paul Cooper  Ken Stein  Tamsin Ford 《British Journal of Special Education》2015,42(3):279-300

Educational policy and the school effectiveness movement often involve rhetoric about the benefit of parent involvement in schools, but high‐quality relationships between parents and teachers are not always straightforwardly achieved, and this may be particularly true in the case of parents of children presenting with academic problems and/or social, emotional and behavioural difficulties. A systematic review of qualitative research was conducted to explore the school‐related experiences of parents of pupils diagnosed with attention deficit hyperactivity disorder (ADHD). Six studies reported in seven papers met the inclusion criteria. High‐quality parent–teacher relationships were found to be the exception, with mothers feeling silenced and criticised. Findings show commonalities with wider research about parents, but identify additional grounds for conflict resulting from parental blame for pupils' disruptive behaviour, and the ambivalent nature of the concept of ADHD.  相似文献
