This study is within the framework of the United Nations sustainable development goals related to equitable quality education. The total score on the 2015 Trends in International Mathematics and Science Study that indicated eighth-grade girls in Jordan significantly outperformed boys is hiding many details related to the quality of mathematics…

The U.S. educational system is undergoing rapid and substantial changes with many states grappling with the adoption of the Common Core State Standards in Mathematics (CCSSM). Important research questions remain unanswered regarding the potential efficacy of the CCSSM to improve student math performance compared with students around the globe.…

The relationship between content readability measures and mathematics test item difficulty was measured. An attempt was made to use readability to predict item difficulty. Results from the study are noted as somewhat discouraging, with only about 11 percent of the item difficulty variance explained by the selected readability measures. (MP)

A program utilizing minicalculators in a mathematics class at the eighth grade level is described. The recommendation is made that the utilization of calculators not exceed one experience per week. (MN)

Almost two-thirds of the eighth graders and preservice elementary teachers tested said that gardens with the same perimeter had the same area. Suggestions for teaching area are given. (MNS)

This study looked at student difficulties with fractions by focusing on understanding of part/whole relationships. The sample consisted of two sixth-grade and two eighth-grade classes. A lack of substantial improvement from sixth to eighth grade on many fraction tasks was noted and viewed as cause for concern. (MP)

Students in seven grade six and eight grade eight classes were involved in this study in which the effect of two versions of the "Mastermind" game on logical reasoning were compared. No differential effects on test performance were found, nor did playing the games promote improved formal reasoning skills. (MNS)

Current practices in teaching about distributivity of multiplication over addition and subtraction are reviewed. Then a study is described in which two inventories were administered to 83 eighth-grade students; scores were low. Suggestions for teaching distributivity are presented. (MNS)

Textbook-worksheet, traditional laboratory, and problem-solving treatments produced no significant differences in achievement by gender or treatment and no difference in perception by gender, but did produce a significant difference in perception by treatment in (n=268) students, grades 7-8.
