This article focuses on elementary school teachers’ preferences for mathematically based (MB) and practically based (PB) explanations.
Using the context of even and odd numbers, it explores the types of explanations teachers generate on their own as well as
the types of explanations they prefer after reviewing various explanations. It also investigates the basis for these preferences.
Results show that teacher-generated explanations include more MB explanations than PB explanations. However, many still choose
to use mostly PB explanations in their classrooms, believing that these explanations will be most convincing to their students.
The implications for teacher education are discussed. 相似文献

This work describes the genesis, articulation and consolidation from 2007 of a social network of b-learning (blended learning) in the UA (University of Alicante) (Spain), with the institutional backing of the Office of the Vice President for Education Technology and Innovation, and the momentum and advice of professor Angel Fidalgo (UNESCO (United Nations Educational, Scientific and Cultural Organization) chair for University of Management and Policy). The social network currently has more than 25 teachers, working on different work linkages with the university, implementing or intending to apply the teaching methodologyb-learning during the course 2007-2008 in a variety of courses and degrees. To do so, several resource centers (blogs, wikis, Wimba Create (before CourseGenie), etc.), and digital platforms (Virtual Campus of the UA, Moodle, etc.) are used. 相似文献

The language development of two deaf girls and four deaf boys in Sign Language of the Netherlands (SLN) and spoken Dutch was investigated longitudinally. At the start, the mean age of the children was 3;5. All data were collected in video-recorded semistructured conversations between individual children and deaf and hearing adults. We investigated the lexical richness and syntactic complexity of the children's utterances in SLN and spoken Dutch, as well as language dominance and interactional participation. Richness and complexity increase over time, as well as children's participation. An important outcome is that syntactic complexity is higher in utterances with both sign and speech. SLN does not have higher outcomes on richness or complexity, but is dominant in terms of frequency of use. 相似文献

Money is everywhere in science. Yet historians have only rarely placed the money trail at the center of their analyses. The essays in this Focus section demonstrate that following the money offers a historiographical path for investigating a number of key issues across disciplinary boundaries in the nineteenth and twentieth centuries. Drawing on cases and materials relating to a number of scientific fields, including electrical engineering, aeronautics, agriculture, and paleontology, the essays examine the continuous role of money in industrial and military patronage, personal connections and networks, and spatial and geographical dimensions of science, as well as in relation to state funding and ownership. Together, the contributions demonstrate how following the money offers a way of overcoming hyperprofessionalism in the history of science. 相似文献

Outcomes and findings from an evidence‐based approach to targeting primary school students’ developmental reading comprehension levels for effective learning are described. Nineteen schools participated in a literacy assessment project designed to monitor and improve the reading comprehension achievement levels of their students. The project integrated a developmental approach to learning and teaching, information derived from standardised reading comprehension assessments, and professional development for teachers. Reading comprehension achievement across the schools increased at a higher rate than typically expected. Teacher discourse about teaching and learning changed from discrete skill and resource focused, to developmentally focused. The centrality of a professional learning team approach to change for the student, teacher and school is discussed. 相似文献

The purpose of this study was to investigate whether using different focus affects electromyographic (EMG) amplitude and contraction duration during bench press performed at explosive and controlled speeds. Eighteen young male individuals were familiarized with the procedure and performed the one-maximum repetition (1RM) test in the first session. In the second session, participants performed the bench press exercise at 50% of the 1RM with 3 different attentional focuses (regular focus on moving the load vs contracting the pectoralis vs contracting the triceps) at 2 speed conditions (controlled vs maximal speed). During the controlled speed condition, focusing on using either the pectoralis or the triceps muscles increased pectoralis normalized EMG (nEMG) by 6% (95% CI 3–8%; p = 0.0001) and 4% nEMG (95% CI 1–7%; p = 0.0096), respectively, compared with the regular focus condition. Triceps activity was increased by 4% nEMG (95% CI 0–7%; p = 0.0308) at the controlled speed condition during the triceps focus. During the explosive speed condition, the use of different focuses had no effect. The different attentional focus resulted in comparable contraction duration for the measured muscles when the exercise was performed explosively. Using internal focus to increase EMG amplitude seems to function only during conditions of controlled speed. 相似文献

ABSTRACTThis study focuses on how postepisodic conflict avoidance is related to the emotional and behavioral reactions to a partner's destructive conflict behavior. The first hypothesis predicted that a partner's destructive behavior is positively related to postepisodic conflict avoidance when an individual becomes emotionally flooded and withdraws during an argument. Conversely, a partner's destructive behavior was expected to be negatively related to postepisodic conflict avoidance when an individual becomes emotionally flooded and reciprocates the destructive behavior during an argument. A path analysis of the accounts of 182 undergraduate participants about a recent conflict episode supported the second hypothesis but not the first. However, results indicate other positive paths between a partner's destructive behavior and postepisodic conflict avoidance. Limitations and future research directions are discussed. This study extends the anger avoidance model and also advances understanding of destructive communication processes. 相似文献

Objective:
This paper presents the methods and results of a study designed to produce the third edition of the “Basic List of Veterinary Medical Serials,” which was established by the Veterinary Medical Libraries Section in 1976 and last updated in 1986.Methods:
A set of 238 titles were evaluated using a decision matrix in order to systematically assign points for both objective and subjective criteria and determine an overall score for each journal. Criteria included: coverage in four major indexes, scholarly impact rank as tracked in two sources, identification as a recommended journal in preparing for specialty board examinations, and a veterinary librarian survey rating.Results:
Of the 238 titles considered, a minimum scoring threshold determined the 123 (52%) journals that constituted the final list. The 36 subject categories represented on the list include general and specialty disciplines in veterinary medicine. A ranked list of journals and a list by subject category were produced.Conclusion:
Serials appearing on the third edition of the “Basic List of Veterinary Medical Serials” met expanded objective measures of quality and impact as well as subjective perceptions of value by both librarians and veterinary practitioners.Highlights
- The 123 journals on the “Basic List of Veterinary Medical Serials” include 117 journals with a decision matrix score of 15 points or higher, with an additional 6 journals included for more complete subject representation.
- Subject categories with the greatest number of journals are internal medicine, food animal medicine, and research.
- Updates for the third edition of the “Basic List” include 59 new titles and 13 new subject categories.
Implications
- The third edition of the “Basic List” provides a useful collection development and assessment tool for veterinary libraries, as well as general libraries with a need to develop a core collection of veterinary resources.
- The decision matrix approach, using standard quantitative and focused qualitative measures, provides a useful methodology for creating core lists in other disciplines.
