Opportunities for learning given to prospective mathematics teachers: between ritual and explorative instruction     

Einat Heyd-Metzuyanim  Michal Tabach  Talli Nachlieli 《Journal of Mathematics Teacher Education》2016,19(6):547-574

The mathematics education field, including prospective teacher education program, has seen a continuous effort to change teaching practices to be more cognitively demanding, conceptually oriented and student centred. Our goal in this study was to examine how certain underlying assumptions about mathematical learning, as reflected in a skilled instructor’s discourse, align with opportunities to learn. The data included a set of fully transcribed 11 lessons from an introductory algebra course. The method of analysis was built upon the communicational (commognitive) framework and included discerning between the instructor’s mathematizing and identifying talk. This framework was extended to quantify the instructor’s identifying talk over the whole set of lessons. Our findings showed that at the surface level, the instruction in the class seemed to align with “explorative” goals. On a deeper level, however, it was more aligned with “ritual” goals that are concerned with producing narratives about people, not about mathematics.  相似文献   

Academic self-efficacy,sense of coherence,hope and tiredness among college students with learning disabilities

Abstract

Some resilient students with LD succeed ‘against the odds’ and reach college. The goals of the study are to explore their resources and barriers during their studies. The relationships between academic self-efficacy (ASE) and personal resources (sense of coherence (SOC) and hope) among college students with learning disabilities (LD) will be examined. The sample consisted of 438 college students divided into two subgroups: 149 students with LD and 289 Non-LD students. Results indicated that college students with LD reported lower levels of ASE, as well as lower levels of hope subscales and SOC. Persistent challenges of early learning distress experienced by those students during school periods continue to be prevalent during their college years. The ASE was predicted by the personal resources, and the risk factor (tiredness lost its significance). The importance of personal resources (SOC and hope subscales) was further emphasised by the mediation model (PROCESS). They mediated the relationships between LD and ASE. These outcomes call for empowering interventional programmes in order to promote hopeful thinking and personal coherence.  相似文献   

The microfluidic system for studies of carcinoma and normal cells interactions after photodynamic therapy (PDT) procedures     

Jedrych E  Chudy M  Dybko A  Brzozka Z 《Biomicrofluidics》2011,5(4):41101-411016

This study reports on the use of a microsystem for evaluation of photodynamic therapy (PDT) procedures on the "mixed" (carcinoma-normal) cultures. Balb/3T3 (normal mouse embryo) and A549 (human lung carcinoma) cells were tested in separated and "mixed" cultures. Interactions and migration of cells cultured together were observed. The PDT procedures were examined in the hybrid (PDMS/glass) microsystem which contains cell culture microchambers integrated with network of microchannels. We investigated that the number of dead cells after PDT procedures is dependent on the kind of cell culture. Moreover, the influence of the carcinoma cells on the viability of normal cells in the "mixed" culture was observed.  相似文献

Novice mathematics teachers create themselves     

Orna Schatz Oppenheimer  Nurit Dvir 《Teacher Development》2018,22(2):210-228

This study presents a qualitative research based on three narratives written by novice mathematics teachers. We examine their unique professional world during their first year of work. The methodology of narrative framework, on which this article is based, helps to gain better understanding of the need for novice mathematics teachers to have pedagogical knowledge. Findings reveal three themes of pedagogical knowledge: the attitude of novice teachers toward students with difficulties in mathematics; parents’ expectations of and involvement with novice mathematics teachers; teacher–student relations. The implications of the findings show that novice mathematics teachers are required to have not only content knowledge of mathematics but also, and above all, pedagogical knowledge. The implications of this study enable reassessment of emphases required in training mathematics teachers, as well as the assistance and support they need, especially as they launch their careers.  相似文献   

Reductive thinking in computer science   总被引：1，自引：1，他引：0  

Michal Armoni  Judith Gal-Ezer  Orit Hazzan 《Computer Science Education》2013,23(4):281-301

This paper discusses the role of reduction in computer science and describes a study on undergraduate students' perception of the concept of reduction. Specifically, based on an analysis of students' answers to questions addressing different computer science topics, we present several findings regarding the ways in which undergraduate students conceive of and apply reduction. These findings can be interpreted within the framework of the tension that exists between the following two factors: The need to think in terms of high levels of abstraction, on one hand, and the fact that reduction introduces a new approach to be used in problem-solving situations, on the other. In addition the paper suggests several teaching applications.  相似文献   

High school computer science education paves the way for higher education: the Israeli case     

Michal Armoni 《Computer Science Education》2013,23(2-3):101-122

The gap between enrollments in higher education computing programs and the high-tech industry’s demands is widely reported, and is especially prominent for women. Increasing the availability of computer science education in high school is one of the strategies suggested in order to address this gap. We look at the connection between exposure to computer science in high school and pursuing computing in higher education. We also examine the gender gap, in the context of high school computer science education. We show that in Israel, students who took the high-level computer science matriculation exam were more likely to pursue computing in higher education. Regarding the issue of gender, we will show that, in general, in Israel the difference between males and females who take computer science in high school is relatively small, and a larger, though still not very large difference exists only for the highest exam level. In addition, exposing females to high-level computer science in high school has more relative impact on pursuing higher education in computing.  相似文献   

Exposure to Violence Across the Social Ecosystem and the Development of Aggression: A Test of Ecological Theory in the Israeli–Palestinian Conflict     

Paul Boxer  L. Rowell Huesmann  Eric F. Dubow  Simha F. Landau  Shira Dvir Gvirsman  Khalil Shikaki  Jeremy Ginges 《Child development》2013,84(1):163-177

Bronfenbrenner’s (1979) ecological model proposes that events in higher order social ecosystems should influence human development through their impact on events in lower order social ecosystems. This proposition was tested with respect to ecological violence and the development of children’s aggression via analyses of 3 waves of data (1 wave yearly for 3 years) from 3 age cohorts (starting ages: 8, 11, and 14) representing three populations in the Middle East: Palestinians (N = 600), Israeli Jews (N = 451), and Israeli Arabs (N = 450). Results supported a hypothesized model in which ethnopolitical violence increases community, family, and school violence and children’s aggression. Findings are discussed with respect to ecological and observational learning perspectives on the development of aggressive behavior.  相似文献   

Exploring young children’s self-efficacy beliefs related to mathematical and nonmathematical tasks performed in kindergarten: abused and neglected children and their peers     

Dina Tirosh  Pessia Tsamir  Esther Levenson  Michal Tabach  Ruthi Barkai 《Educational Studies in Mathematics》2013,83(2):309-322

This article reports on young children’s self-efficacy beliefs and their corresponding performance of mathematical and nonmathematical tasks typically encountered in kindergarten. Participants included 132 kindergarten children aged 5–6 years old. Among the participants, 69 children were identified by the social welfare department as being abused and/or neglected. Individual interviews were conducted where children were asked to assess their self-efficacy regarding sorting tasks, mathematics tasks, and reciting the alphabet. Children were then requested to perform each of the tasks. Results revealed that no significant differences were found between the abused and neglected children and their peers regarding their self-efficacy beliefs and performances for any of the tasks. For some of the tasks, children were able to correctly assess their performance, while for other tasks, children overestimated their performance. Possible reasons for these outcomes are discussed.  相似文献
