小学数学有效课堂教学设计

课堂教学设计的好坏直接决定着课堂教学的效果。只有课前的精心预设,才有可能在课堂上实现精彩的生成。但多数小学数学教师的课堂教学设计仍停留在传统意义上＂课本知识＂的设计层面,缺乏对课程资源、学习情境、学习方式、教师角色、学习群体等多种因素的综合考虑。为此,作为数学教师,只有认真钻研教材,做好＂教学设计＂,才能真正改进课堂教学,有效地提高教师专业水平。     

Classroom practices of cooperating teachers and their relationship to collaboration quality and time: perceptions of student teachers

This study examined the complexities of the collaborative relationship between student teachers and cooperating teachers in secondary mathematics from the perspectives of the student teachers. Four cohorts of student teachers (N = 170) in secondary mathematics were surveyed using a questionnaire that measured their perceptions of two dimensions of their student teaching experience: collaboration with their cooperating teachers and the classroom practices of their cooperating teachers. Although analysis of the responses revealed that student teachers were generally satisfied with the amount and quality of the collaboration, two important results were revealed. First, about half of the respondents reported spending less than an hour collaborating weekly with their cooperating teacher in various contexts. Second, certain classroom practices of the cooperating teachers were found to be significantly associated with whether they spent more or less than an hour collaborating with their student teachers, and were significantly correlated in most cases. This explicit linkage suggests that the classroom practices of cooperating teachers may extend to the mentoring approach they take when working with student teachers. Suggestions for teacher education programs and cooperating teacher support are shared.     

Learning by Exploration in Mathematics Courses: a programme for student teachers

In order to adapt teacher education to new demands in mathematics classrooms, it is necessary to change the courses in mathematics at the university. Teachers’ beliefs about mathematics, learning and teaching has great impact on their teaching. At the University of Göteborg, a co‐operative project has been conducted in order to design a programme based on problem solving in courses taken by prospective Comprehensive School teachers (grade 4‐‐9). The main purpose of the project has been to make student teachers more reflective about mathematics as such, about learning and teaching. Another purpose of the project has been to use a teaching method in a university course‐‐a method which could be applied in a school classroom. The student teachers have worked co‐operatively in small groups of 3‐4 students and the educators role has been that of a facilitator. A preliminary evaluation indicates that student teachers have developed an insight into the complexity of learning and teaching, even though there are variations in this respect. However they still have difficulties in applying the method to teaching mathematics at school.     

Examining the supervision of mathematics student teachers through analysis of conference communications

Student teaching is often a capstone experience in the preparation of mathematics teachers. Thus, it is essential to better understand key aspects of the experience. We conducted a qualitative study of post-lesson conferences led by supervisors (classroom cooperating teachers and a university supervisor) working with mathematics student teachers. Analysis of conference communications revealed differences in the types and content of communications in conferences led by the cooperating teachers and by the university supervisor. Cooperating teachers tended toward evaluative supervision that lacked a focus on the mathematics of the lessons while the university supervisor tended toward educative supervision, guiding student teachers to reflect on and learn from their own classroom experiences including the mathematics of their lessons. Differences are discussed, and suggestions concerning the supervision of student teachers are made along with recommendations for further research.     

Secondary mathematics cooperating teachers’ perceptions of the purpose of student teaching

This article reports on the results of a survey of 45 secondary mathematics cooperating teachers’ perceptions of the primary purposes of student teaching and their roles in accomplishing those purposes. The most common purposes were interacting with an experienced, practising teacher, having a real classroom experience, and experiencing and learning about classroom management. The most common roles were providing the space for experience, modeling, facilitating reflection, and sharing knowledge. The findings provided insights into the cooperating teachers’ perceptions about both what should be learned through student teaching and how it should be learned. These findings paint a picture of cooperating teachers who do not see themselves as teacher educators—teachers of student teachers. Implications for mathematics teacher educators are discussed.     

Relationships between mathematical knowledge for teaching and teaching practice: the case of proof

Teachers of mathematics orchestrate opportunities for interactions between learners and subject matter. Therefore, mathematics teachers need rich, multidimensional content knowledge for teaching mathematics, which incorporates knowledge of the subject matter, students, and teaching. Studying this mathematical knowledge for teaching (MKT) necessitates more than a unidirectional assessment. In this study, the mathematical knowledge for teaching reasoning and proving of two secondary mathematics teachers was investigated through classroom observations and clinical assessments. Results indicate that using MKT as a frame for examining classroom practice, in addition to assessing the MKT a teacher possesses in a clinical setting, provides an in-depth and innovative method for investigating MKT. The comparison of the two cases also identifies student positioning as a key mediating factor between MKT and opportunities to learn. Implications for using MKT as a lens for examining practice in teacher education are discussed.     

数学课堂教学本真性评价之省思

在现实的数学课堂教学评价实践中,教学被异化为评价而不是为了数学课堂教学本身。数学课堂教学评价不能只重"评"的形式而忽视"价"的本质,本真的数学课堂教学评价的价值在于促进学生和教师经由数学教学活动获得发展,它应当是为了数学课堂教学,而不是为了评价本身。本真的数学课堂教学评价不仅基于对数学课堂作为教学基本形式所具有一般课堂性质的正确理解,而且要基于对数学课堂作为数学学科教学实践活动所具有特殊课堂性质的深刻领会。应当重视在数学课堂教学中数学活动这个特殊学科背景意蕴下构建数学课堂教学评价的本真内涵。     

Enhancing the Practicum Experience for Pre-service Chemistry Teachers Through Collaborative CoRe Design with Mentor Teachers

This paper reports findings from an ongoing study exploring how the Content Representation (CoRe) design can be used as a tool to help chemistry student teachers begin acquiring the professional knowledge required to become expert chemistry teachers. Phase 2 of the study, reported in this paper, investigated how collaboration with school-based mentors (associate teachers) on teaching practice (practicum) might impact on this process and student teachers’ development of their pedagogical content knowledge (PCK). The collaboration involved identifying and discussing pedagogical issues related to a practicum-teaching topic using a student teacher’s draft CoRe as a starting point and ongoing focus for the professional dialogue. Practicum offered an opportunity for aspects of student teachers’ PCK, as embodied in their draft CoRes, to be explored and expanded upon in classroom programmes with the support and input of associate teachers. The findings were influenced by different contextual factors; however, the student teachers found their CoRes to be very useful frameworks for engaging in focussed professional dialogue with their teaching mentors. They valued the expertise, currency of knowledge and mentoring of their associates and reported positively about the contribution this support made to their PCK development via the CoRe design process and the transformation of the CoRe into classroom teaching.
