Abstracts of 28 research reports are provided. The reports were prepared by investigators for presentation at the 54th annual meeting of the National Council of Teachers of Mathematics. A broad range of topics related to mathematics education are covered. Three reports concern the effects of differing presentations of mathematics, four are related to attitudes of teachers or students, and three to interactions of personality variables with mathematics learning. Three papers concern problem solving, three deal with logic, and two concern the division algorithm. Other papers concern readability of achievement tests, learning of fractions, measurement, cultural differences in mathematics learning, uses of computer graphics, comparison of calculus courses in high school and college, effectiveness of a remediation program, the use of homework, and field testing of a teacher education program.
