Effective curricular support systems must include resources supporting high-fidelity activity implementation. We examined the frequency of pre-kindergarten teachers' online demonstration video viewing and its association with fidelity of implementation of a math and science curriculum. We found a range in frequency of video viewing and a positive…

Research Findings: Although interest in preschool science is growing, there are few observational measures of science teaching capable of advancing research or supporting professional growth among teachers. To address this gap, the current article presents the development and validation of the Preschool Science Observation Measure (PSOM), which…

We examined the effects of teacher supports in enhancing teachers' open-ended questioning in pre-k activities. The blended teacher supports included online video demonstrations of questioning techniques and companion workshop activities. Twenty-five teachers received the blended supports while the control group did not. The data consisted of…

Development of two-digit place value understanding in the elementary grades has been the subject of some study; however, research at the pre-kindergarten (Pre-K) level is limited. This two-part paper begins by providing an overview of two-digit place value instruction in Pre-K and describes the component parts of a research-based math curriculum,…

Research suggests the importance of professional development for teachers of at-risk children, and while educational technologies can be harnessed to help support teaching practice in innovative ways, such programs are often limited in scale. "My Teaching Partner (MTP)" was designed to deliver a targeted program of professional…

Research Findings: This study examined the impact of MyTeachingPartner-Math/Science, a system of math and science curricula and professional development, on the quality of teachers' interactions with children in their classrooms. Schools were randomly assigned to 1 of 2 intervention conditions (Basic: curricula providing within-activity, embedded…

The "MTP-Math/Science" curricula specifically target the teaching and learning of children at risk of early school failure, a population for whom achievement gaps in mathematics and science are visible even in Pre-K years. "MTP-Math" is based on Focal Areas defined by the National Council of Teachers of Mathematics (NCTM)…
