中学化学教师对虚拟仿真实验室的认可度与应用意愿度调查

分析了虚拟仿真实验室应用于化学实验教育的特点,并通过问卷和访谈调查了中学化学教师对虚拟仿真实验室的认可度与应用意愿度。调查结果显示：绝大多数中学化学教师对虚拟仿真实验室有一定的了解,非常认可其辅助教学、激发实验兴趣、提高实验探究性设计能力的功能;中学化学教师将虚拟仿真实验室应用在未来教学中以及参加相关培训提高虚拟仿真实验教学技能的意愿度也较高;但由于虚拟仿真实验室的建设未能跟进,导致教师使用软件教学的能力不足,而当前一些虚拟仿真软件存在的质量问题也导致中学化学教师对其提高实验动手能力和培养科学严谨性的认可度较低。建议学校完善虚拟仿真实验室的建设工作并加强虚拟仿真实验教学技能培训,虚拟仿真实验室软件开发公司也应与中学化学教师合作提高虚拟仿真实验的设计质量。

专家-熟手-新手教师在化学试题命制中的差异研究——以一道工艺流程题的命制为例

专家、熟手和新手教师基于相同文献命制高中化学工艺流程题,通过试题要素分析、实测结果对比和显著性差异检验,研究专家、熟手和新手教师在化学命题上的差异及差异表现,为提升教师的命题水平提供有益的参考。     

试论新型化学实验评价指标体系的建立

随着教育民主化改革的不断发展,原有的化学实验评价方法已不能适应教育民主的需要。本文提出一种新型化学实验评价指标体系,该体系包括学生自我评价与教师评价 2部分,在教师评价中又采用A、B题“起评分”不同的方式让学生有更多的选择机会。整个评价体系反映了教育民主与一切为了学生发展的教育理念。     

发现化学之美感悟科学魅力

本文指出化学教学的关键,在于引导学生发现化学之美,感悟科学魅力,激发学生的学习兴趣及创造潜能。全文阐述了化学的外在美、揭示了化学的内在美———化学学科思想 (科学之美 )、崇尚化学家的人生之美及化学教师的人格之美。作者认为：化学教师的人格之美源自“以学生发展为本”的教育理念和对学生及化学教育事业的挚爱。本文旨在倡导广大教师更新教育观念,增强自身素质,升华崇高人格,真正实现化学教学中“教师快乐教学,学生享受学习”。     

基于新课程的四川省普通高中化学教师培训需求的调查

以问卷的形式调查了四川省普通高中化学教师的培训需求。结果表明，其培训需求既有共性，即课程标准、微课制作、教学研究方法等；也有差异性，即教学行为、教学设计、评价方式等。因此，建议构建培训方案时，在充分考虑共性和差异性的基础上，选择培训内容，确定培训形式，安排具体的培训时间、频率，以达到增强培训针对性和有效性的目的。     

基于教学反思的化学教师职前教育与专业发展

通过化学职前教师系列"反思性实践"课程，研究师范生教学反思的内容以及基于教学反思促进教师专业发展的有效途径，研究发现对个人教学实践、同课异构、课堂教学点评进行持续的反思，师范生的反思水平呈螺旋式上升，能从反思中发现自己的问题，并能找到原因和改进的策略，对问题或现象背后的原因进行综合分析。     

Implementation and outcomes of inquiry-based learning in mathematics content courses for pre-service teachers

This mixed-methods study describes classroom characteristics and student outcomes from university mathematics courses that are based in mathematics departments, targeted to future pre-tertiary teachers, and taught with inquiry-based learning (IBL) approaches. The study focused on three two-term sequences taught at two research universities, separately targeting elementary and secondary pre-service teachers. Classroom observation established that the courses were taught with student-centred methods that were comparable to those used in IBL courses for students in mathematics-intensive fields at the same institutions. To measure pre-service teachers' gains in mathematical knowledge for teaching, we administered the Learning Mathematics for Teaching (LMT) instrument developed by Hill, Ball and Schilling for in-service teacher professional development. Results from the LMT show that pre-service teachers made significant score gains from beginning to end of their course, while data from interviews and from surveys of learning gains show that pre-service teachers viewed their gains as relevant to their future teaching work. Measured changes on pre-/post-surveys of attitudes and beliefs were generally supportive of learning mathematics but modest in magnitude. The study is distinctive in applying the LMT to document pre-service teachers' growth in mathematical knowledge for teaching. The study also suggests IBL is an approach well suited to mathematics departments seeking to strengthen their pre-service teacher preparation offerings in ways consistent with research-based recommendations.     

Enhancing elementary-school mathematics teachers' efficacy beliefs: a qualitative action research

Individuals and societies that can use mathematics effectively in this period of rapid changes will have a voice on increasing the opportunities and potentials which can shape their future. This has brought affective characteristics, such as self-efficacy, that affect mathematics achievement into focus of the research. Teacher efficacy refers to the extent to which a teacher feels capable to help students learn, influence students’ performance and commitment, and thus plays a crucial role in developing the student in all aspects. In this study, we used two sources of efficacy beliefs, mastery experiences and physiological and emotional states, in an interesting and challenging seven month workshop, as tools to foster teacher efficacy for six elementary-school teachers who were frustrated and wanted to leave their job. Our aim was to study the nature of these teachers’ efficacy in order to change it. In this qualitative action research, we used open interviews, non-participant observations and field notes. Results show that these teachers became efficacious, their students’ achievements and motivation were enhanced, and the school climate was changed. Qualitative inquiry of this construct sheds light on efficacy beliefs of mathematics teachers. Nurturing teacher efficacy has borne much fruit in the field of mathematics in school.
