With the 2015 change in science standards to align more closely with the Next Generation Science Standards, as the district STEM coach, I saw a need for professional development that addressed the lack of understanding and skill needed to teach the Science and Engineering Practices, specifically the practice of Scientific Augmentation. This…

This longitudinal case study explores how students' epistemic uncertainty in argumentation can be adapted as a resource to develop knowledge in a fifth-grade classroom. Major data sources include 12 videotaped whole-class discussions focused on group presentation of arguments to obtain peers' critiques across two course units, the ecosystem and…

A core tenet of the model of domain learning is that learning is shaped by cognitive and motivational forces. In writing, these catalysts include learners' knowledge, motivation, strategic behaviors, and skills. This study tested this proposition at two time points (Fall and Spring) with 179 fifth-grade students (52% were girls), examining if…

We assessed the influence of genre-specific discourse knowledge and writing goals on the persuasive writing of 4th and 6th grade students with and without learning disabilities (LD). Students were first interviewed about their knowledge of persuasion and persuasive writing. They then wrote a persuasive essay about a controversial topic after…

In this quasi-experimental study, 608 fourth-, fifth-, and sixth-grade students explored 5 historical investigations. In the experimental condition, teachers used a cognitive apprenticeship model to teach students historical reading and writing strategies. Comparison teachers used the same materials to deliver a business-as-usual form of…

Making sense of fractions is critical for building the mathematical competence of upper elementary students with and at-risk for a mathematics learning disability. The primary aim of this study was to investigate the effectiveness of teaching students with and at-risk for learning disabilities an intervention in which they learned to construct…

This study developed an analytic framework consisting of four patterns of talk and writing that can support students' engagement in construction and critique: "Talk only," "writing only," "use of talk and writing in sequence," and "use of talk and writing simultaneously." This study aimed to examine how each…

Teaching argumentation with appropriate activities and strategies would support a wide range of goals in science education. Though science labs have been suggested and employed for argumentation activities, such educational expenditures are likely to be beyond the means of most schools in under-resourced areas. Due to the lack of appropriate…

This study examined whether discourse and topic knowledge separately predicted the overall quality and the inclusion of basic genre elements in 5th grade students' stories, persuasive papers, and informational text once the other type of knowledge as well as topic interest, spelling, handwriting fluency, length of text, and gender were controlled.…

The purpose of this study was to determine what students know about the process of writing and the characteristics of stories, persuasive arguments, and informational reports. Participants were 50 grade 5 students. Students responded to questions about writing process and the three different types of writing, and showed a nuanced but relatively…
