A Generative-Predicational Model is proposed and applied to the generation of meanings of simple mathematical word-problems. The model suggests that a fundamental property of cognition is a generative process that takes arguments and that produces results, such as events, answers and inferences. This fundamental property, called predication, generates a task-environment i.e., a problem and its corresponding problem-space i.e., its solution. More precisely, a task-environment is a predication consisting of a written mathematical problem and a writer's life experience. A problem-space is a predication consisting of a leamer's problem solving schema and of the meaning that the learmer generates for the text.The case with which relations can be established between a task-environment and a problem-space depends on the problem's coherence and complexity and the leamer's experiences and thought processes. Faceted definitions of task-environment and problem-space are used to analyze talk-aloud protocols of fifty Israeli sixth-graders tested with thirty word-problems. The empirical results support the proposed model. 相似文献

Perception of suprasegmental features of speech by children with cochlear implants and children with hearing AIDS 总被引：1，自引：0，他引：1
This study assessed perception of suprasegmental features of speech by 30 prelingual children with sensorineural hearing loss. Ten children had cochlear implants (CIs), and 20 children wore hearing aids (HA): 10 with severe hearing loss and 10 with profound hearing loss. Perception of intonation, syllable stress, word emphasis, and word pattern was assessed. Results revealed that the two HA groups significantly outperformed the CI group in perceiving both intonation and stress. Within each group, word pattern was perceived best, and then intonation and emphasis, with syllable stress perceived poorest. No significant correlation emerged between age at implantation and perception of the various suprasegmental features, possibly due to participants' relatively late age at implantation. Results indicated that CI use did not show an advantage over HA use in the perception of suprasegmental features of speech. Future research should continue to explore variables that might improve this perception. 相似文献

This study examined the emotional costs and well-being of postsecondary students with learning disabilities (LD) and attention deficit hyperactivity disorder (ADHD) who faced a sudden shift to emergency remote teaching (ERT) during the COVID-19 pandemic. The study was conducted with 237 postsecondary students in Israel from June to July 2020. With regard to online learning, the LD/ADHD subjects reported significantly higher levels of stress, anxiety, and depression and lower well-being than their neurotypical counterparts. However, no significant differences were found in emotional costs and well-being when the same students had experienced online learning prior to the pandemic. These findings have practical implications for policymakers in academia with regard to the emotional toll of online learning among students with LD/ADHD and their specific needs when facing ERT during the COVID-19 pandemic as well as the contribution of previous online learning when facing ERT. 相似文献

The process of transition from a novice's state to that of an expert, in the constrained domain of decimals, is described in terms of explicit, intermediate, and transitional rules which are consistent, yet erroneous. These rules can be traced to former rules already established in earlier knowledge domains. Empirical data from children at grades 6, 7, 8 and 9 will demonstrate the evolution of an expert's knowledge through an elaborated learning path. 相似文献

Some ideas have dramatically more impact than others – they may overturn existing paradigms or launch new areas of scientific inquiry. Where do such high impact ideas come from? Are some search processes significantly more likely to lead to breakthrough idea generation than others? In this research, we compare “high impact” papers from the social sciences with random-but-matched articles published in the same journals in the same years. We find that search scope, search depth, and atypical connections between different research domains significantly increase a paper's impact, even when controlling for the experience and prior publishing success of the author(s). 相似文献

The introduction of computers into education raises questions such as: are computers in education effective? If they are, in what sense? What are the most effective strategies for using computers in education? How should teachers be encouraged to use them?
To answer these questions a large-scale experiment (Project Comptown) was carried out in Israel, to test ways and means under real rather than laboratory conditions. This project is a research-oriented educational intervention, applying massive computerisation of schools and their 'close environment' to two localities in Israel (Arad and Ashkelon). Our starting point was the premise that computerisation of education is an inevitable process. Consequently, turning the computer into a 'cultural tool' in schools becomes a major challenge, aiming to narrow the gap between 'school culture' and 'real-world culture'. The main objectives for Project Comptown are: [1] To create a computer culture in schools; [2] To use the computer's potential for innovative teaching and learning, both inside and outside schools. To achieve these, we identified a number of principles which we considered pre-conditions for an 'appropriate' computer strategy in schools. 相似文献

One-to-one (1X1) laptop initiatives become prevalent in schools aiming to enhance active learning and assist students in developing twenty-first-century skills. This paper reports a qualitative investigation of all 7th graders and their 15 teachers in a junior high-school in Northern Israel gradually implementing 1X1 model. The research was conducted during a second year of 1X1 implementation at the school level, which was a first year of teaching and learning with laptops for all study participants. The study triangulates non-participant lessons’ observations and semi-structured interviews with 15 teachers. The data were collected twice: at the beginning and toward the end of the 2011–2012 academic year – in total, 30 observations and 30 interviews were conducted. The results were examined through phenomenological research techniques and discussed in terms of the technological, pedagogical and content knowledge (TPACK) and “digital wisdom” approaches. The teachers showed significant increase of technological knowledge. However, only moderate connections between technology and pedagogy as well as between technology and content were found. Some of the teachers functioned as moderators, scaffolding students and supporting their individual or collaborative learning. However, many teachers struggled with effective management of 1X1 classroom. Neither conjunction of teacher TPACK nor facilitation of student digital skills was observed. The paper suggests an overlap of the TPACK framework and the digital wisdom approach and provides implications for curriculum developers and educational policy-makers. 相似文献

In this study, our aim was to understand how environmental education has been implemented in Israeli elementary schools. We selected ten schools that had implemented Education for Sustainability programs and analyzed their mission statements and curriculum documents. We observed each school’s activities and interviewed teachers. Our analysis shows ambiguity with respect to the rationales and the theoretical foundations of the programs. It also shows much didactic teaching of content, a strong focus on behavioral outcomes, especially with respect to reducing resource consumption and to increasing the levels of recycling, as well as some degree of working with the community. The unclear status of environmental education in Israel, in terms of its structure within the education system, prevents it from having sufficient resources for teacher education and curriculum development. It is suggested that this lack of clarity is the main cause of the ambiguity and for the use of the traditional pedagogies we found in our analysis. 相似文献
