The Teaching and Learning International Survey (TALIS) is a large-scale and authoritative international study of teachers. It is conducted by the Organization for Economic Cooperation and Development (OECD) to collect and compare information about teachers and principals in different countries in such key areas as the training and professional development of teachers, performance appraisals, school management and educational goals and practices, job satisfaction, and confidence in one’s professional abilities.  相似文献

The aim of this study was to describe women''s experience of pregnancy. The setting was the Alternative Birth Center at Sahlgrenska University Hospital in Göteborg, Sweden, from 1996 to 1997. Anonymous diaries were written by 12 women and analyzed using a hermeneutical/phenomenological approach. The essential structure and interpretation of women''s experience of pregnancy can be expressed as “transition to the unknown,” which includes three themes: (1) meeting one''s life situation, (2) meeting something inevitable, and (3) preparing for the unknown.The essential structure and interpretation of women''s experience of pregnancy can be expressed as “transition to the unknown” …  相似文献

AIMS: The objective was to describe experiences of sexual abuse occurring before 19 years of age among men and women in León, Nicaragua and to explore the possible association to later sexual risk behavior. METHOD: A sub-sample of literate urban men and women 25-44 years of age was selected from a representative sample of households in León. After an invitation to a public health event, 154 men (53% of the invited) and 213 women (66% of those invited) participated in giving written answers to an anonymous questionnaire. RESULTS: Twenty percent of men and 26% of women reported that they had experienced sexual abuse. Women had been victims of attempted or completed rape twice as often as men, 15% as compared to 7%. Thirty-three percent of the abuse towards boys and 66% of the abuse towards girls was committed by family members. Women who had experienced attempted or completed rape were more likely to later have had a higher number of sexual partners compared to non-abused or moderately abused women. CONCLUSIONS: Sexual abuse of children and adolescents of both sexes is common in Nicaragua. The results underscore the urgent need to address this serious problem more openly, and to make more resources available for the prevention of sexual abuse and for support to victims.  相似文献

This paper describes a collaboration between an urban antipoverty agency, Action for Boston Community Development (ABCD), and a private higher education institution, Lesley College. This collaboration is providing a bachelor's degree program for adults associated with human service agencies. The introductory course, which is the focus of this paper, served to validate the students' experiential learning, helped them gain needed skills, and empowered them to make positive changes in both their perceptions and behaviors. Within a remarkable short period, the individuals in this group made significant changes in their lives. The program described can serve as a model in creating nontraditional partnerships to address the needs of underserved adult populations.  相似文献

Within the field of formative research, there is debate as to whether researchers should collaborate with producers or serve as independent evaluators. The Children's Television Workshop (CTW) produces educational programs through a collaborative process of development that has come to be known as the “CTW Model”. Under the CTW Model, producers, content specialists, and researchers work together throughout the life of a project, from its initial conceptualization through its final production. This paper illustrates the value of the CTW Model via an in‐depth case study of the development and production of a single repeated format within Square One TV, an educational television series about mathematics. In particular, we focus on the multifaceted role played by formative research at all stages of production.  相似文献

Text comprehension requires readers to mentally simulate the described situation by reactivating previously acquired sensory and motor information from (episodic) memory. Drawing upon research demonstrating gender differences, favouring girls, in tasks involving episodic memory retrieval, the present study explores whether gender differences exist in mental simulation in children (Grades 4 to 6). In Experiment 1, 99 children performed a sentence–picture verification task measuring mental simulation at sentence level. In Experiment 2, 97 children completed a lexical decision task in which imageability of words was manipulated to measure mental simulation at word level. Only for girls we found faster reaction times for matching versus mismatching sentence–picture pairs (Experiment 1) and high‐imageability versus low‐imageability words (Experiment 2). The results suggest that girls construct more coherent and vivid mental simulations than boys and rely more heavily on these representations. The results emphasize the importance of including gender into reading comprehension research.

Abstract

This exploratory study aimed to describe the impact of the ‘Science in Family project’, as a transformative learning model for science teachers trying to improve student’s attitudes toward STEM subjects. This study took place in a public elementary school in Monterrey, Mexico, which has been developing this project for more than thirteen years with students from 4th, 5th and 6th grade. We used participant observation and interviews with four families whose children are students of this elementary school, and with one family whose sons were students of this school some years ago. Results showed that there is a relationship between positive attitudes towards science in students who were exposed to transformative learning models of teaching. Two of the participants took steps to follow science related careers. This study helps to illuminate the extent to which teacher education models influence students’ attitudes and how positive attitudes to science are influenced by the use of learning by doing projects.  相似文献

Our objective was to test the factorial validity of the different versions (TSES-24, TSES-12, and TSES-11) of the Teacher's Sense of Efficacy Scale in Spanish preservice teachers'. The participants were 358 preservice teachers. The confirmatory factor analysis showed inadequate fit indexes for both TSES-24 and TSES-12 but adequate fit indexes for TSES-11, which was invariant across gender. The reliability analysis showed appropriate values. The global factor for teachers' sense of efficacy and the three factors that constitute it positively predicted intrinsic motivation and life satisfaction. The global factor for sense of efficacy and the classroom management and student engagement factor negatively predicted amotivation. The results support the use of the TSES-11 three-factor model, rather than TSES-24 or TSES-12, for Spanish preservice teachers.  相似文献
