Teachers’ Discussions Of Students’ Thinking: Meeting The Challenge Of Attending To Students’ Thinking     

Michelle?T.?ChamberlinEmail author 《Journal of Mathematics Teacher Education》2005,8(2):141-170

The purpose of this article is to describe findings from a study of teachers’ social interaction during discussions about students’ thinking. The goal of the discussions was for the teachers to interpret their students’ thinking as revealed from work on non-routine, thought-revealing mathematical tasks, known as model-eliciting activities. The research reported in this article focuses on instances during the discussions when the teachers engaged in what the researcher termed ‘mini-inquiries’, occasions during which the teachers inquired into why their students thought about the associated model-eliciting activities as they did or when the teachers inquired into the underlying mathematical complexities associated with the model-eliciting activities. During these mini-inquiries, the teachers typically engaged in one of four types of interaction patterns that enabled them to meet some of the challenges of attending to students’ thinking that are described in United States reform documents.  相似文献   

Purification and relationship with gastric disease of a 130 kDa (CagA) protein of<Emphasis Type="Italic">Helicobacter pylori</Emphasis>

Objective: The aims of this research were to purify and identify the 130 kDa (CagA) protein ofH. pylori clinical isolate HP97002 and evaluate the relationships between the purified 130 kDa (CagA) protein and gastric diseases. Methods: The procedure for isolating the protein included 6 mol/L guanidine extract, size exclusion chromatography and elusion from gel. Sera of 68 patients with gastric diseases (44 with chronic gastritis, 15 with atrophic gastritis, 7 with peptic ulcer disease, 2 with gastric cancer) were obtained, and the serological response to CagA was studied by Western-blot using the purified protein. Results: The purified protein was 130 kDa and preserved good antigenicity and revealed basic isoelectric point about of 8.1. Among 68 sera, 43 sera could recognize the purified protein associated with chronic gastritis 47.7% (21/44), atrophic gastritis 86.7% (13/15), peptic ulcer disease 100% (7/7), gastric cancer 100% (2/2). Compared with each other, the difference was significant (χ²=13.327,P=0.004), and 130 kDa (CagA) protein was associated with severe gastric diseases (r _s=0.442,P=0.001). Conclusion: The 130 kDa (CagA) protein was associated with severe gastric diseases. Project supported by the China Medical Board (96-628) and Zhejiang Province Hygiene Bureau (2000 A055)  相似文献   

Human causality judgments and response rates on DRL and DRH schedules of reinforcement     

Reed P 《Learning & behavior》2003,31(2):205-211

The effect of various relationships between a response (an investment made in the context of a game) and an outcome (a return on the investment) on judgments of the causal effectiveness of the response was examined. In Experiment 1, response rates and causal judgments were higher for a differential-reinforcement-of-high-rate (DRH) schedule relative to a variable-ratio (VR) schedule with the same probability of outcome following a response. Response rates were also higher for a DRH than for a variable-interval schedule matched for reinforcement rate. In Experiment 2, response rates and causal judgments were lower for a differential-reinforcement-of-low-rate schedule relative to a VR schedule with the same probability of outcome following a response. These results corroborate the view that schedules are a determinant of both response rates and causal judgments, and that few current theories of causal judgment explicitly predict this pattern of results.  相似文献   

Development of auditory event-related potentials in young children and relations to word-level reading abilities at age 8 years     

Espy KA  Molfese DL  Molfese VJ  Modglin A 《Annals of dyslexia》2004,54(1):9-38

A relationship between brain responses at birth and later emerging language and reading skills have been shown, but questions remain whether changes in brain responses after birth continue to predict the mastery of language-related skills such as reading development. To determine whether developmental changes in the brain-based perceptual skills are systematically related to differences in word-level reading proficiency at age 8 years, brain event-related potentials (ERPs) to speech and nonspeech stimuli were recorded annually at the ages of 1 through 8 years in a sample of 109 typically developing children. Two measures of word-level reading (one that requires decoding of real words and one of pseudowords) were administered at age 8 years. Growth curve analysis, using the hierarchical linear models, related reading performance (average versus low) to the longitudinal maturation in the ERP waveform peak and latencies. Maturational changes (e.g., slope, acceleration, and cubic growth) in N1 amplitude from ages 1 to 4 were related to proficiency in decoding pseudoword stimuli only, with children who were less proficient in decoding pseudowords evidencing more steeply negative declines in amplitude with age, particularly at the frontal and parietal recording sites in response to both speech and nonspeech stimuli. In contrast, proficiency in decoding real words was related to developmental changes in N2 amplitudes from ages 4 to 8 only at the parietal recording site, and only in response to nonspeech stimuli. The early development of biologically based differences in the perception and processing of auditory information contributes to later group differences in reading proficiencies at school age.  相似文献   

Teachers' learning to facilitate high‐level student thinking: Impact of a video‐based professional development          下载免费PDF全文

Attaining the vision for science teaching and learning emphasized in the Framework for K‐12 Science Education and the next generation science standards (NGSS) will require major shifts in teaching practices in many science classrooms. As NGSS‐inspired cognitively demanding tasks begin to appear in more and more science classrooms, facilitating students' engagement in high‐level thinking as they work on these tasks will become an increasingly important instructional challenge to address. This study reports findings from a video‐based professional development effort (i.e., professional development [PD] that use video‐clips of instruction as the main artifact of practice to support teacher learning) to support teachers' learning to select cognitively demanding tasks and to support students' learning during the enactment of these tasks in ways that are aligned with the NGSS vision. Particularly, we focused on the NGSS's charge to get students to make sense of and deeply think about scientific ideas as students try to explain phenomena. Analyses of teachers' pre‐ and post‐PD instruction indicate that PD‐participants began to adopt instructional practices associated with facilitating these kinds of student thinking in their own classrooms. The study has implications for the design of video‐based professional development for science teachers who are learning to facilitate the NGSS vision in science classrooms.  相似文献   

What Can Clients Tell Us about Seeking Counselling and Their Experience of It?     

Robert?J.?MantheiEmail author 《International journal for the advancement of counseling》2005,27(4):541-555

Research on counselling is often unknown to or ignored by counsellors. Research that explores counselling from the client’s perspective is even less familiar to most counsellors, perhaps because there is far less of it compared to the quantity of research investigating the process from the counsellor’s point of view. Nevertheless, research presenting the client’s perspective can be a useful guide to both counsellors and their clients. With this aim in mind, this article summarises some of the research that has been conducted from the client’s point of view and suggests implications for counselling practice.  相似文献   

Formation des Enseignants et Petites Communautes Europeennes: finalités culturelles spécifiques?     

Jacques‐Andre Tschoumy 《欧洲师范教育杂志》1989,12(1):5-11

A parity of prestige is fundamental to tomorrow's multi‐cultural, multilingual Europe. It is an obligation for all educational systems, whether large or small, sovereign or second‐tier, autonomous or struggling for independence.

This mini‐tour of Europe's small communities is dedicated to the promotion of this parity, and it takes teacher education as its entry‐point. A real first’ for the European Journal of Teacher Education, this introduction is dedicated to the examination of teacher‐education policies in those communities which history has marginalised in territory, in population or in legal status. Do they have specific characteristics? Are there ways in which they are interdependent?

This survey presents five case studies, most of them located in the centre of Europe (Luxembourg, Liechtenstein, Andorra, Ticino, the Orisons). But Europe offers many instances: Malta, Cyprus, Friesland, the German communities in Belgium and Denmark, Monaco, San Marino, Scotland, Ireland, the Basque countries, Catalonia, the south Tirol, the Swiss Jura, the Welsh, Bretons, Alsatians, Corsicans, etc.

Multi‐cultural Europe is theirs too, and this study invokes others which may contribute to the evolution of our simple, closed, national technosystems into European ecosystems which will be both complex and open.  相似文献   

Gender Differences in Child Aggression: Relations With Gender‐Differentiated Parenting and Parents’ Gender‐Role Stereotypes          下载免费PDF全文

This longitudinal study examines the association between child gender and child aggression via parents’ physical control, moderated by parents’ gender‐role stereotypes in a sample of 299 two‐parent families with a 3‐year‐old child in the Netherlands. Fathers with strong stereotypical gender‐role attitudes and mothers were observed to use more physical control strategies with boys than with girls, whereas fathers with strong counterstereotypical attitudes toward gender roles used more physical control with girls than with boys. Moreover, when fathers had strong attitudes toward gender roles (stereotypical or counterstereotypical), their differential treatment of boys and girls completely accounted for the gender differences in children's aggressive behavior a year later. Mothers’ gender‐differentiated parenting practices were unrelated to gender differences in child aggression.  相似文献   

Students’ Perceptions of Mental Health Counseling in the United Arab Emirates (UAE)     

Jesse?A.?BrinsonEmail author  Fatima?Salem?Saeed?Al-amri 《International journal for the advancement of counseling》2005,27(4):495-512

Counseling services in the United Arab Emirates (UAE) have focused on counseling in the elementary and secondary schools. To date, the idea of the private practitioner of mental health counseling has been virtually nonexistent. However, education officials at the University of the United Arab Emirates (UAE) have been exploring the option of following the international trends of preparing students for mental health counseling services, with special emphasis in marriage and family. A counselor education degree would allow individuals to operate private practices to address various concerns that impact individuals within the society at large. No instruments that measure perceptions of counseling from an international perspective were found for the purposes of this study. Therefore, it was necessary for the authors to devise and test a new tool. Surveys were completed by a sample of 141 undergraduate students regarding their perceptions of the importance of counseling in UAE society and the role of the counselor in society and other general questions regarding perceptions of counseling. With this initial effort, psychometric properties of the ‘Perceptions about Counseling Survey’ appeared promising. Results revealed that students had a favorable view toward the role of the counselor in UAE society. Results further revealed that students perceived the counseling profession as favorable. Given that the participants were predominately female, the results were analyzed from the social and cultural perspective of women in Arab society and the social psychological theory of ‘attitude’ is considered as a contextual backdrop.  相似文献   

Relationships between different instructional approaches and students' Classical Chinese reading comprehension and motivation     

Kit‐ling Lau 《Journal of Research in Reading》2019,42(3-4):523-540

Previous studies comparing teacher‐centred (TC) and learner‐centred (LC) instruction have presented a mixed picture of the effectiveness of these two instructional approaches. By examining the effectiveness of different types of instruction on students' Classical Chinese (CC) reading comprehension and motivation, this study aims to contribute to instructional research by elucidating the positive and negative aspects of TC and LC instruction when they are applied in the context of teaching CC reading. A total of 454 Secondary 4 students between the ages of 15 and 17 years agreed to participate in this study on a voluntary basis. They completed a CC reading comprehension test and a questionnaire that measured their CC reading motivation and perceived CC reading instruction. Relationships between students' perceived CC reading instruction, reading motivation and reading comprehension were examined by correlation and path analyses. The findings of the correlation analyses indicated that traditional TC instruction positively and significantly correlated with students' CC reading performance and extrinsic motivation. Motivating tasks, one type of LC instruction, positively and significantly correlated with all types of motivation but did not significantly correlate with CC reading performance. In the path analysis, TC instruction exhibited a significant positive effect on reading comprehension, whereas motivating tasks continued to exhibit a significant positive effect on intrinsic motivation after the effect of the examined schools' achievement level was controlled for. The findings highlight the essential role of teachers in instructing students who are weak in particular subjects. Instead of viewing TC and LC instruction as two contradictory approaches, the findings indicate that a combined approach of TC and LC instruction can more effectively facilitate students' learning in a difficult school subject.  相似文献
