Math anxiety impedes performance in simple arithmetic tasks. Anxiety constrains working memory capacity and particularly the attentional functions of the central executive. The experiment reported here explored how interactivity mitigated the impact of math anxiety on the performance of elementary school students with simple additions. It manipulated two independent variables. The first was the length of the additions—involving either 7 or 11 number tokens (the value of the tokens ranged from 1 to 20). The other was the level of interactivity: in the low interactivity condition participants could not touch or point to the number tokens that configured the sums, and in a high interactivity condition participants could manipulate the tokens as they saw fit in deriving their answer. The length of the addition had an impact on accuracy, with longer sums leading to poorer performance. However, overall, performance in the high interactivity condition was superior, in terms of accuracy, absolute calculation error and efficiency, than performance in the low interactivity condition. Mathematics anxiety significantly predicted performance in the low interactivity condition, but not in the high interactivity condition. These results suggest that working memory resources are augmented through interactivity with the physical problem presentation, defusing the impact of anxiety on performance. 相似文献

The relationship between language and executive function (EF) and their development in children have been the focus of recent debate and are of theoretical and clinical importance. Exploration of these functions in children with a peripheral hearing loss has the potential to be informative from both perspectives. This study compared the EF and language skills of 8- to 12-year-old children with cochlear implants (n = 22) and nonimplanted deaf children (n = 25) with those of age-matched hearing controls (n = 22). Implanted and nonimplanted deaf children performed below the level of hearing children on tests assessing oral receptive language, as well as on a number of EF tests, but no significant differences emerged between the implanted and nonimplanted deaf groups. Language ability was significantly positively associated with EF in both hearing and deaf children. Possible interpretations of these findings are suggested and the theoretical and clinical implications considered. 相似文献

The extent to which cognitive development and abilities are dependent on language remains controversial. In this study, the analogical reasoning skills of deaf and hard of hearing children are explored. Two groups of children (deaf and hard of hearing children with either cochlear implants or hearing aids and hearing children) completed tests of verbal and spatial analogical reasoning. Their vocabulary and grammar skills were also assessed to provide a measure of language attainment. Results indicated significant differences between the deaf and hard of hearing children (regardless of type of hearing device) and their hearing peers on vocabulary, grammar, and verbal reasoning tests. Regression analyses revealed that in the group of deaf and hard of hearing children, but not in the hearing group, the language measures were significant predictors of verbal analogical reasoning, when age and spatial analogical reasoning ability were controlled for. The implications of these findings are discussed. 相似文献

This paper shows the planning, the teaching activities and the evaluation of the learning and teaching process implemented in the Chemical Process Design course at the University of Cantabria, Spain. Educational methods to address the knowledge, skills and attitudes that students who complete the course are expected to acquire are proposed and discussed. Undergraduate and graduate engineers' perceptions of the methodology used are evaluated by means of a questionnaire. Results of the teaching activities and the strengths and weaknesses of the proposed case study are discussed in relation to the course characteristics. The findings of the empirical evaluation shows that the excessive time students had to dedicate to the case study project and dealing with limited information are the most negative aspects obtained, whereas an increase in the students' self-confidence and the practical application of the methodology are the most positive aspects. Finally, improvements are discussed in order to extend the application of the methodology to other courses offered as part of the chemical engineering degree. 相似文献

University graduate-level programs are striving to address needs for community college leaders. One way they are doing this is by strengthening their graduate programs with relevant community college courses. Increasingly, however, community college presidents are being invited to join universities in professorial roles. These new graduate faculty leaders are bringing valuable transferable skills and experiences, but they are also experiencing transitional challenges. Studies have been conducted about other university executive administrators transitioning to university professor roles, but no studies have been conducted about community college presidents making this transition. This article represents an initial effort to explore a distinct class of leaders within academe—community college presidents-turned-professor. The findings of this exploratory study of 12 former community college presidents who transitioned to graduate university professors are reported along with stories, lessons learned, and advice for successfully crossing over from the community college sector to the university one. 相似文献

AbstractThis study examines the temporal effect of different trainings designed to favour the development of false belief understanding. A sample of 78 pre-school children aged between three years, five months and three years, 11 months was divided into three training conditions. After three training sessions, they were immediately evaluated in post-test 1 and again a month and a half later in post-test 2. The results showed that the efficiency of the training conditions depended both on the type of linguistic communication and on the use of deceptive objects. Also, the effect of the training was maintained for at least a month and a half after post-test 1 and it was transferred from the trained task to other false belief tasks. The results are commented according to the possibility of using language-based trainings to foster children’s theory of mind understanding in educational contexts. 相似文献

This paper studies the influence of poultice type and application techniques on the desalination efficiency of two limestone substrates having similar porosities (22–25%) but different pore size distributions: microporous Bateig Novelda and macro porous Tosca Rocafort stones. Three poultice types are compared: pure sepiolite (fine porous), sepiolite and aggregate (medium porous), and pure cellulose powder (coarse porous). Four application techniques are studied: (i) direct application on the stone, (ii) pre-wetting before poultice application, (iii) Japanese paper before application, and (iv) pre-wetting?+?Japanese paper before application. Samples were taken from poultices on the one hand, and from substrates at different depths on the other hand. Their content in soluble salts was estimated by ionic conductivity measurements. After three application runs, the best result for both substrates is achieved with the combined application of coarse- and fine-porous poultices (FPs) (desalination depth: 4.5/6?cm for macro/micro-porous substrates). The FP is also able to extract salts properly, but the desalination depth achieved is less important (3?cm). A direct poultice application without pre-wetting nor Japanese paper is to be preferred for both stone types. 相似文献

This article discusses how student disengagement is conceptualized by English-speaking youth attending English urban public schools in Montreal, Quebec. School dropout is theorized as being a culminating event in a process of school disengagement (Rumberger, 2011). Using 2 qualitative methods (maps and interviews) in a grounded theory approach (Charmaz, 2014), a theory of disengagement is presented and supported by existing literature in student engagement and school dropout. Student disengagement is framed from a socio-ecological perspective (Lawson &; Lawson, 2013) in a move away from its predominant conceptualization as an individual trait. In doing so, we highlight some issues of urban education in Montreal, addressing such themes as inequity, low-income status, experiences of failure and the pass/fail paradigm, the elementary/secondary school transition, normativity, and, finally, the public/private distinction in schooling. 相似文献

Educational Psychology makes a significant contribution to the development of skills to research the effectivity of teacher practices in class. However, there is little agreement on what educational psychology concepts are most relevant for teacher training. This paper reports on trainee teachers’ self-perceived mastery of, and attributed importance to, the syllabus content of the Learning & Development module taken as part of the BA Primary Education programme at a university in Barcelona (Spain). Data were collected through a questionnaire answered by all the participants (N = 561) and a focused interview conducted with a representative sample (n = 24). Results showed that students attributed greater importance to syllabus topics related to socio-emotional development and teaching roles in the classroom. Theoretical topics, such as conceptual frameworks for development and learning, were less rated. Students reported deficient mastery of the syllabus topics and significant gaps between attributed importance and self-perceived mastery of contents were confirmed. Implications of our study results for teaching psychology to primary school pre-service teachers are discussed. 相似文献

The power of analysis of covariance (ANCOVA) and 2 types of randomized block designs were compared as a function of the correlation between the concomitant variable and the outcome measure, the number of groups, the number of participants, and nominal power. ANCOVA had a small but consistent advantage over a randomized block design with 1 participant in each Block × Treatment combination (RB1). At correlations of .3 or greater, ANCOVA was superior to a randomized block design with n participants per Block × Treatment combination (RBn), with increasing differences as the correlation increased. RBn was superior to the other 2 designs only when the correlation was .2 or less. At those levels, however, the randomized group analysis of variance ignoring the concomitant variable was equally powerful. The findings held regardless of sample size, number of groups, or nominal power. 相似文献
