高级统计学的教学实践与思考

基于教学实践和调查问卷对研究生高级统计学的各个教学环节进行了探讨和分析.区别于本科生的统计学教育,在研究生的统计教学中,不仅要介绍统计方法,而且还要通过更加有效的手段加强研究生对统计分析方法的整体认识和应用能力.教学实践和对调查问卷的统计分析结果表明:将传统的解释性教学和演示性教学与现代的具有建构主义特征的发现学习相结合将有助于培养研究生的学习能力和科研能力.     

Reflective Pathways: Analysis of an Urban Science Teaching Field Experience on Noyce Scholar‐Science Education Awardees' Decisions to Teach Science in a High‐Need New York City School

Awardees of the National Science Foundation's Noyce Scholars funds are required to teach science in high‐need urban or rural school districts upon graduation. The purpose of this research was to analyze the reflective considerations that distinguish preservice Noyce Scholar science education majors committed to teaching in high‐need New York City (NYC) schools from those committed to high‐need rural careers. Essays designed to expose their (n = 22) considerations of teaching in NYC written before, immediately after, and two weeks following a one‐week cultural and science teaching internship experience were coded to reveal distinguishing reflective thought patterns. The results showed that those (16/22) whose final essay showed commitment to NYC teaching viewed themselves positively as NYC teachers and that increases in positive self‐perceptions were paralleled by increases in affinity toward living in NYC and NYC schools. Those not inclined to NYC teaching (6/22) expressed increasingly negative views of themselves as NYC teachers, NYC life, and urban education generally. The research provides insights into what Noyce Scholar undergraduates in science education think about when considering a teaching career in urban school districts.
