Sixty (35 girls) ninth graders were assessed on measures of algebraic reasoning and usage of visual and symbolic representations (with a prompt for visual use) to solve equations and inequalities. The study grouped visual representations into two categories: arithmetic-visual, which entailed the use of real-world objects to represent specific…

Direct linkLuz, Yael; Yerushalmy, Michal – Journal for Research in Mathematics Education, 2023
We report on an innovative design of algorithmic analysis that supports automatic online assessment of students' exploration of geometry propositions in a dynamic geometry environment. We hypothesized that difficulties with and misuse of terms or logic in conjectures are rooted in the early exploration stages of inquiry. We developed a generic…

Anika Alam; A. Brooks Bowden – Society for Research on Educational Effectiveness, 2024
Background: The importance of high school completion for jobs and postsecondary opportunities is well- documented. Combined with federal laws where high school graduation rate is a core performance indicator, school systems and states face pressure to actively monitor and assess high school completion. This proposal employs machine learning…

Gaslin, William L. – 1974
This paper reports the results of a ten-week study investigating the use of electronic calculators to perform basic operations with rational numbers in ninth-grade mathematics classes. In all, six classes and 101 students were involved. A short literature review is given and three treatments are described. Dependent variables were five mastery…

Carifio, James – 1975
The present study devised a computerized assignment-by-preference algorithm for a ninth-grade exploratory curriculum. The problem addressed was one of maximally mapping all students into 8 of 12 vocational programs in terms of their preferences for studying each of the programs and the assignment restrictions established by the school. To minimize…

Higher order cognitive development and success in the study of high school mathematics and science require an understanding of rational number concepts and facility with proportional reasoning and computation. Proportional reasoning is an essential schema for developing formal operational thought. This study involving 16 ninth-grade students was…
