Alphabetic orthographies vary in the (in)consistency of the relations between spelling and sound patterns. In transparent orthographies, like Italian, the pronunciation can be predicted from the spelling, in contrast to opaque orthographies such as English, where spelling–sound correspondences are often inconsistent. The pronunciation of English vowel letters is in particular very ambiguous. In this paper, we provide a cross-linguistic investigation of orthographic transparency at the word-initial letter–phoneme level, resulting in ranked metrics for the seven languages investigated- Dutch, English, French, German, Hungarian, Italian, and Portuguese, expressed as entropy values. We focus on the contributions of vowels and consonants towards the overall orthographic transparency and provide evidence that deviations from consistent word-initial 1:1 mappings between letters and phonemes influence reaction times in naming tasks. Implications for theories of visual word recognition and speech production will be discussed. 相似文献

Purpose: The purpose of this study is to investigate the impact of interpersonal communication on the adoption of agri-environmental measures (AEM) by organic farmers in Germany.
Methodology: The study used the logit model to predict the probability of adoption behaviour, and Social Network Analysis (SNA) was conducted to analyse the question of whether validating information about organic farming provided by interpersonal information sources is associated with communication frequency.
Findings: Our findings demonstrate that being an early adopter of organic farming practices and frequent contact with young and highly educated farmers increases the probability of adoption of other AEM. However, contact frequency in interpersonal networks was found not to be a significant determinant for explaining adoption decisions. Frequently communicating farmers in the network are more likely to attribute higher levels of importance to organic farming information received from formal actors than to information received from informal actors.
Practical Implications: If young and highly educated farmers, who can be considered as informal opinion leaders, are approached by the extension services, then an effective diffusion of information on AEM can be expected. To support the AEM adoption, a platform should be provided by state agencies that would enable organic farmers to understand the environmental benefits achieved over the time.
Originality/value: This study contributes to the scientific discussion on the role of interpersonal communication on AEM adoption. A new aspect is our consideration of organic farmers adopting additional AEM. Moreover, we highlight organic farmers' validation of the importance of formal and informal information sources on organic farming. 相似文献

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country. 相似文献

The present multimethod longitudinal study aimed at investigating development and stability of implicit memory during infancy and early childhood. A total of 134 children were followed longitudinally from 3 months to 3 years of life assessing different age‐appropriate measures of implicit memory. Results from structural equation modeling give further evidence that implicit memory is stable from 9 months of life on, with earlier performance predicting later performance. Second, it was found that implicit memory is present from early on, and no age‐related improvements are found from 3 months on. Results are discussed with respect to the basic brain structures implicit memory builds on, as well as methodological issues. 相似文献

While principal goal-setting has been shown to be an important leadership practice, there is little research examining principals’ goal-setting and goal-achievement. This research examined novice principals’ school improvement goals and factors affecting their achievement. Goals from 460 principals enrolled in a national induction programme were categorised revealing a strong emphasis on instructional and student-centred leadership. After 18 months, 258 of those principals, and their mentors, rated their achievement. Principals also rated five potential achievement predictors. Goal achievement tended to be high, with commitment, effort, learning and support serving as positive predictors of success. In contrast to what goal-setting theory suggests, goal challenge was a negative predictor of achievement. The analysis of two contrasting cases revealed possible explanations for this negative relationship. These included novice principals’ ability, self-efficacy and attributional processes. This study highlights the role of self-efficacy in the process of goal-setting and pursuit. It emphasises that consideration needs to be given to how novice principals’ self-efficacy can be developed and sustained. Implications for practice in the area of educational leadership and leadership development are discussed. 相似文献

Patterns of literacy learning in German primary schools over the summer and the influence of home literacy practices 下载免费PDF全文
下载免费PDF全文 The ‘summer learning effect’ (SLE) is described as a stall or drop in achievement over summer, especially in schools serving poor or ‘minority’ communities. There has been little research in Europe on the effect, and research internationally has primarily focused on the effect in reading, with minimal focus on writing. This paper describes the extent and nature of the SLE in reading comprehension and writing in second grade classrooms in Germany. The SLE was evident in both subject areas with all students experiencing lower progress rates over summer. In reading, students attending the high‐income school progressed significantly more over summer than their low‐income peers, while there was no significant difference in writing progress over summer. Literacy logbooks over summer and interviews with a subset of students provided information on how home literacy practices influenced the effect. 相似文献
