The Effects of Instruction in Estimation on the Problem Solving Performance of Second Grade Students. A Research Project Report.
Sikes, Lenell D.
A pretest-posttest control group design was used in a classroom experiment designed to determine whether the problem-solving performance of second grade students would be affected by systematic instruction in estimation. Participants were 36 students in two groups who were given daily lessons in measurement. The experimental group received a daily lesson in measurement mathematics that included estimation activities. The control group received daily mathematics lessons on measurement that included other types of measurement activities. Findings revealed a significant difference at the .05 level in the mean score differences between groups. It is concluded that second grade students benefit from measurement estimation lessons and activities. This type of instruction should be considered by teachers as a means of teaching estimation skills to second grade students. Appendices provide the pre- and posttest measures, 28 lesson plans for experimental and control groups, and statistical calculations. A total of 46 references are cited. (RH)
