Developing Mathematical Thinking: Changing Teachers’ Knowledge and Instruction
نویسندگان
چکیده
In the present research, we evaluated the effectiveness of a multi-year professional development program in mathematics for elementary teachers. Each year the program focused on a different domain of mathematics. We found the program increased teachers’ knowledge of (a) number and operations, (b) measurement and geometry, and (c) probability and statistics. We also examined the relation between mathematical knowledge and teaching practices. Across the three domains neither pretest nor posttest mathematical knowledge were related to classroom teaching practices. However, change in knowledge was positively related to six different dimensions of teaching practice for number and operations, and for measurement and geometry; and was positively related to four or six dimensions for probability and statistics. That is, those teachers with greater changes in knowledge demonstrated more effective instruction.

متن کاملTeachers’ metacognitive knowledge and the instruction of higher order thinking
The purpose of the present study was to investigate teachers’ declarative metacognitive knowledge of higher order thinking skills. This was a qualitative study conducted within the educational setting of in-service science teachers’ courses. The main finding is that teachers’ intuitive (i.e., pre-instructional) knowledge of metacognition of thinking skills is unsatisfactory for the purpose of t...

Research on the effect of implicit and explicit instruction on developing learners’ explicit knowledge by the use of measures of explicit knowledge abounds in the literature. However, measuring learners’ implicit knowledge employing fine-grained measures has rarely been the concern of researchers in the field. Therefore, the present study is an attempt to scrutinize the effectiveness of implici...
