This publication is a compilation of abstracts and critical comments for 12 published investigations in mathematics education. Information for each study includes: purpose; rationale; research design and procedures; findings; and interpretations. For each study also, abstractor's comments provide a brief critique. The 12 studies are: (1) "Mathematical Problem-Solving Performance of Eighth-Grade Programmers and Nonprogrammers"; (2) "Three Decade Comparison of Elementary Teachers' Mathematics Courses and Understandings"; (3) "Students' Miscomprehension of Relational Statements in Arithmetic Word Problems"; (4) "Sex Differences in Learning Mathematics: Longitudinal Study with Item and Error Analysis"; (5) "Effects of CAI with Fixed and Adaptive Feedback on Children's Mathematics Anxiety and Achievement"; (6) "Structuring and Adjusting Content for Students: A Study of Live and Simulated Tutoring of Addition"; (7) "Usefulness of Tables for Solving Word Problems"; (8) "Early Developments in Children's Use of Counting to Solve Quantitative Problems"; (9) "Mathematics Classrooms in Japan, Taiwan, and the United States"; (10) "Calculators and Instruction in Problem Solving in Grade 7"; (11) "Integers as Transformations"; and (12) "Learning Mathematics from Examples and by Doing". Also provided are lists of mathematics education research studies reported in journals as indexed by "Current Index to Journals in Education" and "Resources in Education" for July through September of 1987.
