In this study we extend our prior exploration focused on the extent to which middle school teachers appropriately identified proportional situations and whether there were relationships between attributes of the teachers and their ability to identify proportional situations. For this study, we analyzed both a larger dataset (n = 32) and two…

Over the past several years, research teams have developed observational instruments to measure the quality of teachers' instructional practices. Instruments such as Framework for Teaching (FFT) and the Classroom Assessment Scoring System (CLASS) assess general teaching practices, including student-teacher interactions, behavior management, and…

Two investigations of fifth graders' strategies for locating whole numbers on number lines revealed patterns in students' coordination of numeric and linear units. In Study 1, we investigated the effects of context on students' placements of three numbers on an open number line. For one group ("n"?=?24), the line was presented in a…

Since the late 1990s, there has been consensus among educational researchers that argumentation should play a central role in science education. Although there has been extensive relevant research, it is not clear enough how oral argumentation spontaneously occurs in science teaching. This is particularly important with regard to the empirical…

This study examined how evidence of students' mathematical understanding was influenced by elementary schoolteachers' enactment of instructional practices emphasized during a mathematics professional development program. Videos and field notes were collected during lessons for two teachers from the program and two matched comparison teachers.…

Unlike most research, which has primarily examined the players' interest in or attitude toward game-based learning through questionnaires, the purpose of this empirical study is to explore students' engagement patterns by qualitative observation and sequential analysis to visualize and better understand their game-based learning process. We…

The purpose of this study was to examine adolescent's hostile attributions of mother's intent and emotional self-expectancies as contributors to expression of emotion between mothers and adolescents. Data were collected from 268 10- to 12-year-olds (133 girls, 135 boys) and their mothers. Each dyad was observed in a conversational activity that…

In school, deaf and hard of hearing students (d/hh) are often exposed to American Sign Language (ASL) while also developing literacy skills in English. ASL does not have a written form, but is a fully accessible language to the d/hh through which it is possible to mediate understanding, draw on prior experiences, and engage critical thinking and…

Teacher-educators and policy-makers recognize that ongoing training and support for high quality implementation of curricula can be a vital component of systems that ensure the value of education experiences, particularly for students at-risk of school failure (Meisels, 2007; Pew Charitable Trusts, 2007; Pianta, 2005). In particular, there is…

Teams of educators conducted lesson study independently, supported by a resource kit that included mathematical tasks, curriculum materials, lesson videos and plans, and research articles, as well as protocols to support lesson study. The mathematical resources focused on linear measurement interpretation of fractions. This report examines the…
