This paper outlines the design of a physics textbook that addresses issues of gender-inclusive physics teaching, STS and constructivism.
Difficulties of addressing these issues in a textbook for normal classes, which has to compete with other textbooks on the
market will be discussed.
Specializations: constructivist approaches in science education research and practice.
Specializations: gender issues in science instruction.
Specializations: primary education, integrated science.
Specializations: STS, phenomenological oriented physics instruction.
Specializations: peace education within science education. 相似文献

INTRODUCTION The world population of buffaloes(Bubalus bubalis)has been estimated at over172million head,more than97%(167.6million)of which are in Asia and the Pacific region,mainly in India(97.7million)and Pakistan(25.5million)(FAO,2004).About98%of buffaloes in the region are raised by small farmers owning less than two hectares of land and less than five buffaloes(Mudgal,1992).In general,the water buffalo is regarded as more productive,healthier and more useful than the cow,especiall… 相似文献

The interrelationship among language components is the main conceptual framework for this study which examined the written language performance of Jamaican children with severe to profound hearing loss. Twelve subjects aged 15 to 16 years completed text level tasks in writing, reading and sign language. Hearing children aged 13 to 14 years completed writing and reading tasks. Multilevel analyses were undertaken. Differences and parity in performances were observed within and between groups at the word, sentence and text levels. Deaf children's ability to express complex ideas in sign language in the Jamaican education system indicated a need for nontraditional approaches in the teaching of written language. Suggestions are outlined for developing an instructional model to enhance written language using a bilingual approach. 相似文献

A cowse‐integrated programme of library instruction has been developed for the School of Civil Engineering at the Queensland University of Technology, Australia; library instruction being one of the means selected to improve the research efforts of fourth year project students. The programme has been developed through consultation between the Civil Engineering Research Project Coordinator and the Civil Engineering Reference Librarian. Its aims are derived from those established for the fourth year research projects. Attention is focussed on the nature of the programme and the impact of instruction on fourth year research project students. Students who had received extended library instruction were compared with students from the previous year. Evidence suggests that the instruction has improved the information seeking behaviour of the students and their literature reviews. 相似文献

In this study, the reading comprehension of deaf children and adolescents in the Netherlands is examined along with their
word identification. The reading comprehension of 464 deaf students and the word identification of 504 deaf students between
6 and 20 years of age was examined. The results show the reading comprehension scores of deaf children to be far below the
scores of hearing children. On average, the deaf subjects scored at a level equivalent to a hearing child in the first grade.
The word identification scores of the deaf children, however, were almost equivalent to the scores of hearing children. Although
reading comprehension and word identification appear to be related, this relation does not completely explain the comprehension
difficulties encountered by deaf children. Additional factors are required to explain deaf children’s difficulties with reading
comprehension. 相似文献

A previous meta-analysis indicated that eight instructional factors--Questioning, Sequencing and Segmentation, Skill Modeling, Organization and Explicit Practice, Small-Group Setting, Indirect Teacher Activities (e.g., homework), Technology, and Scaffolding-captured the majority of successful intervention programs for adolescents with learning disabilities (LD). Most important was the Organization/Explicit factor, which contributed significant variance (16%) to effect size. This factor included two important instructional components: advance organization and explicit practice. In this article, we convert these findings into practical guidelines to direct instructional practice. 相似文献

This article reports on the experiences of two lecturers working at the University of Tasmania required to teach outdoor and sustainability education (O&SE) courses online. Using an (auto)ethonographic case-study approach, the lecturers were interviewed with a view to exploring their perceptions, challenges, ethical dilemmas, tensions, opportunities and experiences in this space. A number of themes emerged, including commitment to quality teaching and learning, the role of experience, and experiential learning, in the online space, the challenge of fostering a connection to place, difficulties faced when trying to develop a learning community, and the role of professional learning and support in terms of pedagogy and technology in the online space. These themes, and their implications for teaching and learning in higher education both generally, and specifically in O&SE, are discussed in light of what is a mounting body of literature exploring the move to online delivery in higher education. 相似文献
