Abstract: | Research, aimed at constructing an instrument for measuring instructional climate, was conducted in 121 Dutch schools for senior general secondary education. The instrument comprised scales for students, teachers, heads of department and principals. All scales proved to be sufficiently reliable and valid. The results show that the following variables are significantly related to students' results in mathematics: students' enjoyment of mathematics; students' attitude towards high grades; students' enjoyment of learning; appreciation of how teachers prepare students for tests; students' appreciation of the teacher as a person; students' appreciation of teaching abilities; an orderly instructional climate in the classroom; frequent monitoring of student results; emphasizing achievement by teachers; and the principals' emphasis on a task oriented climate. |
