Providing opportunities for students to demonstrate their mathematical thinking can be challenging. This paper reports on a case study conducted with a teacher and her class of Grade 3/4 students which investigated this phenomenon. Following collection of baseline data that showed her students were not demonstrating evidence of mathematical…

Preparing students for entry into kindergarten is a key priority within the educational sector. Research has shown that students with lower levels of cognitive and socio-emotional competencies are less prepared for kindergarten entry and consequently perform more poorly on assessments in later grades (Duncan et al., 2007; Ensey Hoever, 2014;…

In this study, we investigated one student as she engaged in the exploration of a graph theory problem, the Graceful Tree Conjecture. The study took place in a classroom in the Midwestern United States which contained eighteen students. We report on a descriptive case study of one student, Heidi, as she works her way through different classes of…

We analyzed the effects of a game-based, supplemental fraction curriculum on fourth and fifth grade students' fraction knowledge, engagement, and STEM interest. Students with and without disabilities with intersecting identities (e.g., race, disability status, gender) comprised the sample. Results indicate significant differences in fraction…

Identifying components of teaching that make a difference in children's learning is an ongoing challenge in our field. Focusing on teaching that is responsive to children's fraction thinking, we decomposed responsiveness into the instructional practices of questioning to support and extend children's thinking, noticing children's thinking, and…

This paper proposes structural modification of the Clarke and Hollingsworth (2002) Interconnected Model of Teacher Professional Growth (IMTPG) based on results from doctoral research that studied the changes in mathematical knowledge and beliefs of two Year 5/6 teachers as they implemented a four-week, innovative curriculum unit. These inclusions…

This paper presents primary school teachers' perceptions associated with their engagement in a project aimed at building Year 3 and Year 4 students' number fact and computational fluency. Throughout the project, teachers were provided with classroom ideas and suggestions for engaging students in number fact practice and for generating student…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program designed to develop upper-elementary students' vocabulary skills in order to improve reading comprehension. The study used a true, group-randomized, experimental design, which randomly assigned 46 4th grade classrooms (n=1324 students) from 12 districts…

This paper advocates the use of the Dynamic Approach (DA) to promote Student Self-Assessment (SSA) for formative purposes. DA is based on the assumption that professional development should be differentiated to meet teachers' needs, while engaging them into guided critical reflection. A sample of 45 teachers was randomly allocated into two groups:…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program to improve elementary students' vocabulary skills and reading comprehension. The study used a multi-site cluster randomized, experimental design, which randomly assigned 92 4th grade classrooms (n=2558 students) from two cohorts to a treatment or control…

This paper reports on results of a targeted and extended (two school terms) program for building Grade 3 and Grade 4 students' facility with number facts and application for mental computation. As part of a larger project, this paper reports results from two schools. Results indicated strong gains in number fact recall and mental computation for…

Inquiry science instruction is especially challenging in elementary grades where teachers are constrained by crowded curricula and time. Professional development (PD) may provide an opportunity to support elementary teacher development of inquiry science instruction. The study examines the inquiry practice of two teachers who participated in an…

We present main effects of treatment and moderating effects of student background on science and engineering outcomes for grades 3-5 children participating in an engineering intervention. Data is from a large-scale randomized-controlled trial of two matched pairs (intervention and comparison) of engineering units. The intervention curriculum…

The effects of morphological instruction on reading and writing outcomes was investigated with 4th and 5th grade classrooms. Growing research supports the incorporation of morphologically-based instruction for vocabulary, reading, and spelling outcomes. However, little work has investigated writing outcomes. Classrooms were assigned to implement…
