To be successful, an instructional video presentation needs to be effective, valued, liked and efficient, and educationalists and designers should strive (explicitly and implicitly) to satisfy these criteria. In the interests of optimum teaching effect, a didactical distinction is recommended between video presentations that have to ‘instruct’, ‘explain’, ‘tell’ and ‘let encounter’. A schema or frame of reference is proposed, the use of which (it is claimed) can help to optimise communication between video producer, teacher and instructional designer  相似文献

The language competence and reading comprehension of 406 7‐year‐old children are examined in the research discussed in this article. The children were tested using comparative tests as part of an international project conducted in 14 countries and sponsored by the IEA and the High Scope Research Foundation in Ypsilanti, USA. The discussion here relates only to a part of this wider research and focuses upon the aims and contents of Polish language teaching in grades I—III of the Polish primary school.  相似文献

Undergraduate students who major in science make diverse career choices. Two such career choices are medical technologists and science teachers. One possible reason for science majors selecting different career choices might be attributed to varied personality dimensions. The purpose of this study was to identify a set of personality attributes that distinguish practicing medical technologists from practicing science teachers. The subjects of this study consisted of 83 medical technologists and 57 science teachers. Eysenck Personality (EPI) was utilized to investigate the personality attributes of subjects in terms of Eysenck's personality variable of Extroversion-Introversion and Neuroticism-Stability. Vocational Preference Inventory was utilized to investigate the vocational personality profile of subjects in terms of Holland's classification of occupations and work environment. Data with EPI revealed that there was no significant difference between medical technologists and science teachers with respect to Eysenck's personality variable of extroversion. However, there was found a significant difference between the two groups with respect to Eysenck's personality variable of neuroticism. Data with VPI revealed that there was no significant difference between medical technologists and science teachers with respect to Eysenck's personality variable of extroversion. Both the groups were characterized by the personality profile of IAS (Intellectual-Artistic-Social). This profile was different from that required earlier in literature.  相似文献

The teachers' role in the integration of science and technology studies within the recent educational reform in Israeli junior high schools was addressed within a case study. Eight science teachers and three technology teachers participated in in‐service training courses and received individual tutoring. Data were obtained through school visits, interviews with management, teachers, and tutors. Pupils' performance on a science‐technology project was assessed by an achievement test and a questionnaire. Science teachers preferred to extend their content knowledge and didactic skills in science. Technology teachers lacked basic scientific knowledge. A realistic aim is to expose the science teacher to the field of technology, and the technology teacher to the realm of science, to the extent that will enable him or her to cooperate with the teacher in the parallel domain, rather than train a teacher to teach both. © 1999 John Wiley & Sons, Inc.

The research investigated the association between school engagement and adult education and occupation outcomes, within the context of a 1985 Australian longitudinal national cohort study of the factors affecting children's long‐term health and well‐being. School engagement may be more modifiable than other factors related to academic success, such as academic attainment, which is influenced by family background. A School Engagement Index was constructed using questionnaire items on school enjoyment and boredom. Related school engagement items included learner self‐concept, motivation to learn, sense of belonging, participation in school or extra‐mural activities, and enjoyment of physical activity. In 2004–2006, participants (aged 26 to 30 years) reported their highest level of education achieved and current occupation. Potential covariates included age, sex, markers of socio‐economic status in childhood, personality and school‐level variables (i.e., number of students, single sex versus co‐education; government, private or independent). Logistic regression was used to estimate the odds of achieving post‐compulsory school education and achieving higher status occupations. Findings revealed that each unit of school engagement was independently associated with a 10% higher odds (OR 1.10 95% CI 1.01,1.21) of achieving a post‐compulsory school education. Maternal education, self‐concept as a learner, motivation to learn, all also significantly predicted achieving post‐compulsory school education. School engagement was found to mediate the association between the personality characteristic of agreeableness and education outcomes. Higher school engagement was also independently associated with achieving higher status occupations 20 years later (OR 1.11 95% CI 1.03, 1.20). Importantly, this was independent of a host of background factors.  相似文献

Disoriented, punitive, and caregiving/role‐confused attachment behaviors are associated with psychopathology in childhood, but have not been assessed in adolescence. A total of 120 low‐income late adolescents (aged 18–23 years) and parents were assessed in a conflict‐resolution paradigm. Their interactions were coded with the Goal‐Corrected Partnership in Adolescence Coding Scales. Confirmatory factor analysis demonstrated that the three disorganized constructs (punitive, caregiving, and disoriented interaction) were best represented as distinct factors and were separable from a fourth factor for collaboration. The four factors were then assessed in relation to measures of attachment disorganization, partner abuse, and psychopathology. Results indicate that forms of disorganized behavior first described in early childhood can also be reliably assessed in adolescence and are associated with maladaptive outcomes across multiple domains.  相似文献

This four‐wave prospective longitudinal study evaluated stability of language in 324 children from early childhood to adolescence. Structural equation modeling supported loadings of multiple age‐appropriate multisource measures of child language on single‐factor core language skills at 20 months and 4, 10, and 14 years. Large stability coefficients (standardized indirect effect = .46) were obtained between language latent variables from early childhood to adolescence even when accounting for child nonverbal intelligence and social competence and maternal verbal intelligence, education, speech, and social desirability. Stability coefficients were similar for girls and boys. Stability of core language skill was stronger from 4 to 10 to 14 years than from 20 months to 4 years, so early intervention to improve lagging language is recommended.  相似文献

Lean six sigma is a management methodology that firms can employ to achieve substantial improvement in supply chain performance. However, few pedagogical exercises facilitate students’ use of a comprehensive set of lean six sigma principles within a supply chain context. We describe the Airplane Supply Chain Simulation that helps students understand how lean six sigma concepts may be leveraged to improve supply chain performance. The basis of this simulation is a four‐tier supply chain, consisting of suppliers (two tiers), a manufacturer, and a customer, that produces three models of paper airplanes to meet randomly distributed customer demand. In the first of three successive runs, a highly structured simulation is executed in which supply chain roles are well defined, material flows are convoluted, and a “push” production strategy is followed. The first simulation as the “current state” and, for the second and third simulation runs, challenge competing student teams to leverage lean six sigma concepts to develop a “future state” that enables the fulfillment of all customer orders at the lowest cost. Results based on statistical analyses of survey response data from 194 MBA students show that the Airplane Supply Chain Simulation is an effective participative, team‐based learning tool.  相似文献

A formal model of the scientific communication process is presented using the IDEF0 notation. The model provides a roadmap for policy discussions and further research. In comparison to earlier models it is more detailed and hierarchical, and includes more modelling constructs. It includes the whole communication value chain, from initial research to the assimilation of research results to everyday practice. Although the model treats both informal and formal communication, as well as the publishing of data, its focus is on modelling the publishing and indexing of traditional peer‐reviewed journal articles, and finding and retrieving them. New developments enabled by the Internet, such as open access journals and e‐print repositories, are also included.  相似文献

The programme of the Département de la Formation Internationale at Ecole Nationale des Ponts et Chausées (ENPC) was created in 1981 to address the ever‐increasing international role of today's engineer in the scientific, economic and social spheres. Each year, 75 ENPC students spend at least 3 months abroad, mainly in Europe. ENPC has double degree programmes in engineering studies with three European partners in Germany and Spain: TU Munich and TU Berlin; Universidad Politécnica de Madrid. Twenty per cent of the student curriculum is devoted to language study; the students are required to study English plus one of the following languages: German, Spanish, Italian, Russian, Japanese or Chinese. French courses for foreign students are also provided. Language teaching aims to provide students not only with the linguistic skills necessary for communication, but also to make them more sensitive to other cultures as well as their own.  相似文献
