In December of 1986 and January of 1987, questionnaires on teaching practices in science and mathematics were sent to elementary school principals in Indiana. The first questionnaire, completed by 301 administrators, concerned manipulative use of materials in science and mathematics. The second questionnaire, completed by 317 administrators, contained questions dealing with problem-solving instruction and use of computers in science and mathematics. Results of the study include findings that: (1) manipulatives were used to teach science more frequently in grades 3-5 than in grades K-2; (2) manipulatives were used to teach mathematics more frequently in grades K-2 than in grades 3-5; (3) problem-solving was given greater emphasis in grades 3-5 than in grades K-2 in science and mathematics; (4) computers were used for science and mathematics instruction more in grades 3-5 than in grades K-2, and (5) drill and practice was the most common application of the computer to science and mathematics instruction. Tables are provided in the text; copies of the questionnaires are included in the appendix. (Author/TW)
