This research examined the range of reading fluency and comprehension scores of 1,149 students in five diverse elementary schools, including a gifted and talented magnet school. Results revealed a range in reading comprehension across all schools of 9.2 grade levels in Grade 3, 11.3 in Grade 4, and 11.6 in Grade 5. A similar wide range of oral reading fluency scores was found across all elementary schools, as students scored from below the 10th percentile to above the 90th percentile. These results demonstrate the wide range of reading achievement in diverse populations of students, including gifted students, and the need for teachers to differentiate both reading content and instruction to enable all students to make continuous progress in reading.

The goal of Project M2 was to develop and field-test challenging geometry and measurement units for K-2 students. The units were developed using recommendations from gifted, mathematics, and early childhood education. This article reports on achievement results for students in Grade 1 at 12 diverse sites in four states using the Iowa Tests of Basic Skills (ITBS) mathematics concepts subtest and an open-response assessment. Using HLM, as expected there were no statistical differences between the experimental (n = 186) and comparison (n = 174) groups on the ITBS (91% of the items focused on number). Statistically significant differences (p < .001) favoring the experimental group were found on the open-response assessment with a large effect size (d = 1.88). Thus the experimental group exhibited a deeper understanding of geometry and measurement concepts on the open-response assessment while performing as well on a traditional measure that covered all Grade 1 mathematics.

The purpose of this study was to determine whether relationships existed between teachers' implementation of two specific discourse-related instructional practices and students' mathematics achievement in geometry and measurement as part of a research study on the effectiveness of an advanced mathematics curriculum for kindergarten and Grades 1 and 2. The mathematics units incorporated the following instructional practices: engaging students in verbal communication in mathematics and encouraging the use of appropriate mathematical vocabulary. Hierarchical linear modeling was used to determine the relationships between teachers' use of the instructional practices and the students' mathematics achievement. Results indicated that significant, positive relationships existed; the teachers' implementation scores for the verbal communication and encouraging mathematical language instructional practices were predictors of student mathematics achievement as measured by students' percentage gain scores on the Open-Response Assessments. Implications of these findings for mathematics instruction are discussed.

This study compared the characteristics of second graders' mathematical writing between an intervention and comparison group. Two six-week Project M2 units were implemented with students in the intervention group. The units position students to communicate in ways similar to mathematicians, including engaging in verbal discourse where they themselves make sense of the mathematics through discussion and debate, writing about their reasoning on an ongoing basis, and utilizing mathematical vocabulary while communicating in any medium. Students in the comparison group learned from the regular school curriculum. Students in both the intervention and comparison groups conveyed high and low levels of content knowledge as indicated in archived data from an open-response end-of-the-year assessment. A multivariate analysis of variance indicated several differences favoring the intervention group. Both the high-and low-level intervention subgroups outperformed the comparison group in their ability to (a) provide reasoning, (b) attempt to use formal mathematical vocabulary, and (c) correctly use formal mathematical vocabulary in their writing.The low-level intervention subgroup also outperformed the respective comparison subgroup in their use of (a) complete sentences and (b) linking words. There were no differences between groups in their attempt at writing and attempts at and usage of informal mathematical vocabulary.
