关于中国安全科学技术一级学科建设的研究

我国"安全科学"从确立发展至今,经历了劳动保护科学及其体系创建和发展阶段,安全科学技术一级学科确立、以经济发展为目标、安全科学重点建设和发展安全生产科学科技阶段以及当前的以人为本、安全发展的安全科学发展和完善等3个阶段。安全科学技术应与环境科学、管理科学、生态科学、信息科学、社会科学和伦理科学等学科交叉综合,以拓展安全科学的内涵,推动安全科学的发展。     

Understanding the Language Demands on Science Students from an Integrated Science and Language Perspective

This case study of a science lesson, on the topic thermal expansion, examines the language demands on students from an integrated science and language perspective. The data were generated during a sequence of 9 lessons on the topic of ‘States of Matter’ in a Grade 7 classroom (12–13 years old students). We identify the language demands by comparing students' writings with the scientific account of expansion that the teacher intended the students to learn. The comparison involved both content analysis and lexicogrammatical (LG) analysis. The framework of Systemic Functional Linguistics was adopted for the LG analysis. Our analysis reveals differences in the meaning and the way LG resources were employed between the students' writings and the scientific account. From these differences, we found the notion of condition-of-use for LG resources to be a significant aspect of the language that students need to appropriate in order to employ the language of school science appropriately. This notion potentially provides a means by which teachers could concurrently address the conceptual and representational demands of science learning. Finally, we reflect on how the complementary use of content analysis and LG analysis provides a way for integrating the science and language perspectives in order to understand the demands of learning science through language.

Science in the Trenches: An Exploration of Four Pre-service Teachers' First Attempts at Teaching Science in the Classroom

This paper explores four students' attempts at teaching science in the real world classroom during their initial student teaching practicum, including their struggles and successes. When pre-service teachers enter their initial practicum experience they are confronted with differing teaching philosophies of their own, their university professors, and their school mentors (Sullivan, Mousley & Gervasioni, 2000; John, 2001; Fu and Shelton, 2002). Within this situation, preservice teachers struggle to find their own niche of teaching science and learn to reflect as both learner and teacher (Kelly, 2000). Our goal as science teacher educators is to help pre-service teachers have an easy transfer from personal university experiences to teaching science in the real classroom environment while maintaining the integrity of newly learned teaching strategies (Segall, 2001). This work adds to and helps guide science teacher educators in identifying difficulties pre-service teachers' experiences in the transition from methods courses to practice.
