A discussion is presented concerning variables associated with children's representation of certain addition and subtraction problems. Problem components are classified as physical, pictorial, sensual, verbal-spoken, verbal-written, symbolic, or internal. Problems are discussed as abstract (symbolic) or nonsymbolic. Three problem components are…

This bulletin presents research findings about the interpersonal relationships between science and mathematics teachers and their students. This research is based on studies that used the Questionnaire on Teacher Interaction which gathers data on students' and teachers' perceptions of interpersonal teacher behavior. A reproducible copy of the…

The application of a linear learning model, which combines learning theory with a structural analysis of the exercises given to students, to an elementary mathematics curriculum is examined. Elementary arithmetic items taken by about 100 second-grade students on 26 weekly tests form the data base. Weekly predictions of group performance on…

Five newsletters examine a variety of topics dealing with learning disabilities. Topics include the following: ways to help learning disabled (LD) seniors plan for higher education, transitional college programs, the changing role of neurologists in the field of LD, the place of math in the education of LD students, instructional reasons for LD…

Following a brief historical review of the mechanism of mathematical modeling, examples are included that associate a mathematical model with given data (changes in sea level) and that model a real-life situation (process of parallel parking). Also provided is the rationale for the curricular implementation of mathematical modeling. (JJK)

Presented are student activities that involve two standard problems from geometry and calculus--the volume of a box and the bank shot on a pool table. Problem solving is emphasized as a method of inquiry and application with descriptions of the results using graphical, numerical, and physical models. (JJK)

These nine articles reflect the diversity of activities taking place in adult education and adult literacy in the Boston area. An introduction briefly describes each article; notes on the authors follow. In "A Different Third 'R'--Radical Math," Marilyn Frankenstein describes a mathematics course that, through content and method, both…
