This issue of "Investigations in Mathematics Education" contains: (1) a review of E. Fischbein's book "The Intuitive Sources of Probabilistic Thinking in Children;" (2) nine abstracts of research studies in mathematics education; (3) a list (by EJ number) of mathematics education research studies reported in the January to March 1984 issues of "Current Index to Journals in Education" (CIJE); and (4) a list (by ED number) of mathematics education research studies reported in the January to March 1984 issues of "Resources in Education" (RIE). The studies abstracted focus on: the influence of different styles of textbook use on instructional validity of standardized tests; directional effect in transformational tasks; a comparison of scaling and correlational analysis of perceptions of mathematics objectives; attitudinal differences between students in general mathematics and algebra classes; homework assignments, mathematical ability, and achievement in calculus; engaged student behavior within classroom activities during mathematics classes; the acquisition of addition and subtraction concepts in grades 1 through 3; an evaluation of a process-oriented instructional program in mathematical problem-solving in grades 5 and 7; and mathematics anxiety, instructional method, and achievement in a survey course in college mathematics.
