There is growing recognition that mathematical modeling can be a lever for equity in elementary mathematics classrooms. This study focuses on the impact of a professional development program focused on culturally responsive mathematical modeling on 8 kindergarten through 2nd grade teachers' practices in modeling lessons. We use a project developed…

There is an educational expectation that children's natural drawing will develop into proficient mathematical representations and formal diagrams, yet there is little research available to guide the assessment and development of children's mathematical drawing skills. The aim of this paper is to explore how Year 2 children (approx. 7 years) chose…

This study reports on an early career Year 2 teacher's reflections of enacting specifically structured resource materials and her practice change when participating in a mathematics professional learning project. A qualitative case study was designed to examine the reflections of a teacher's pre-service and in-service teaching experiences. Data…

In this investigation we propose new machine learning methods for automated scoring models that predict the vocabulary acquisition in science and social studies of second grade English language learners, based upon free-form spoken responses. We evaluate performance on an existing dataset and use transfer learning from a large pre-trained language…

In this year-long randomized control trial (RCT), we evaluated the effectiveness of a year-long, intensive, and structured virtual professional development (VPD) accompanying science-integrated English-as-second-language (ESL) instructional intervention on 187 second grade English learners' English language and literacy development in suburban…

This is a report of a professional development project. The purpose of the project was to provide professional development to teachers in vocabulary instructional strategies and to examine vocabulary acquisition of English language learners. The participants were 8 second grade ELL students and 6 second grade teachers. The eight second grade…

There is an ongoing debate over the psychophysical functions that best fit human data from numerical estimation tasks. To test whether one psychophysical function could account for data across diverse tasks, we examined 40 kindergartners, 38 first graders, 40 second graders and 40 adults' estimates using two fully crossed 2 × 2 designs, crossing…

Literacy coaching has become a prevalent mode of PD and a significant expenditure in many school districts--fulfilling components of high-quality PD, as it is job-embedded, ongoing, focused on student learning, and providing opportunities for practice and feedback on instruction. The field, however, abounds with reports of teacher resistance to…

This paper introduces a revised model for the development of basic computation skills. The model draws on four key phases, which have proven to be important for the development of calculation strategies and stresses the use of gestures and the verbalisation of concrete and mental images. This seems to be of crucial importance for children with…

This paper details how a 7-month reading-focused professional development initiative, centered on the assessment-to-instruction cycle, supported teachers' growth by combining small group sessions with related individualized literacy coaching. Analysis of participants' experiences revealed the significance of differentiated professional learning in…

Using an experimental research design, this project investigated the effects of teacher read-alouds when students did, and did not, have access to companion texts. Based on Connectionist theory, the researchers hypothesized that students in the Companion Text group would outperform students in the Listen Only group on the three examined variables:…

This paper presents the results of a study of the structural development of young students' drawings of arrays, and in particular, the significance of using lines instead of drawing individual squares. Students' array drawings were classified on basis of numerical properties, and perceived structural similarities that reflected the spatial…

Perhaps the greatest challenge facing educators of today is to create and sustain high-quality educational environments for low-income students and students of color. The Boston Pilot Schools Network, a network of eleven small, innovative schools within the Boston Public Schools, can be a model for other schools and districts as to how to create…

One mathematics lesson was planned by two Grade 2 teachers together. Their separate teaching of it was videotaped, and each teacher was interviewed before and after her lesson. The "same" lesson resulted in different sets of worthwhile learning outcomes. In this research report, the notion of situated cognition is used as a tool for analysis of…

This paper explores the Counting development of Australian children participating in the Early Numeracy Research Project (ENRP) who were identified as low-attaining using an individually administered assessment interview and a research informed framework of growth-points. The progress of Grade 1 and Grade 2 children who participated in an…
