Abstract
In this article I described the means of identifying teaching behaviors that have cognitive and affective learning effects on students who are taking a course in mathematics. This study was conducted on 50 mathematics teachers who were teaching in the eighth grade. I obtained the data on teaching behaviors through direct systematic observation. Multiple regression was used as the method of analysis. For the cognitive domain, the results showed that effective teaching behaviors are: (a) high-level questions put to a large group of students; (b) probing, followed by a correct student response; (c) teacher waiting after asking a question; (d) successful redirecting; and (e) all forms of positive acknowledgement. Effective teaching behaviors in the affective domain are: (a) all forms of teacher lecture/explanations; (b) probing, followed by correct student response; and (c) all forms of positive acknowledgement. More teaching behaviors have a positive effect on mathematical knowledge than have a positive effect on students’ attitude toward mathematics.
