We present lessons learned from an ongoing attempt to conceptualize, develop, and refine a way for teachers to gather formative assessment evidence about classroom argumentation as it happens. The system--named DiALoG (Diagnosing Argumentation Levels of Groups)--includes a digital scoring tool that allows teachers to assess oral classroom…

The various types of interactions that students carry out when engaged in scientific argumentation function together to move forward developing ideas and support sensemaking. As such, incorporating argumentation in classroom instruction holds promise for supporting students in developing and acting with an epistemic agency, being positioned, and…

Abstract For students to meaningfully engage in science practices, substantive changes need to occur to deeply entrenched instructional approaches, particularly those related to classroom discourse. Because teachers are critical in establishing how students are permitted to interact in the classroom, it is imperative to examine their role in…

At the 2015 "NARST: A Worldwide Organization for Improving Science Teaching and Learning Through Research" Annual International Conference, a group of scholars held an extended pre-conference workshop to discuss key challenges and future directions faced by argumentation researchers around the world. This wide-ranging group of…

Science teachers need support in developing pedagogical content knowledge (PCK) around science practices such as argumentation. Educative curriculum materials (ECMs) have great potential as a tool to support teachers' PCK development, particularly for in-service teachers. In this chapter, we describe an intervention in which we developed and…

Argumentation, a key epistemic practice in science, engages students in socially constructing knowledge claims using evidence. However, teachers need support in integrating argumentation into classroom instruction. We examined teachers' enactments of an educative science curriculum and their curricular decision making for argumentation. Ten middle…

Despite the recent emphasis on science practices, little work has focused on teachers' knowledge of these key learning goals. The development of high quality assessments for teachers' pedagogical content knowledge (PCK) of science practices, such as argumentation, is important to better assess the needs of teachers and to develop supportive…

In this article, we describe the development process for designing multimedia educative curriculum materials (MECMs) focused on supporting teachers in argumentation. We also describe results from a study with 46 teachers. We were interested in whether teachers' backgrounds or characteristics of the MECMs impacted MECM use. Overall, 89% of the…

Ensuring all students have opportunities to engage in scientific argumentation is a key goal for K-12 students. While research has shown that teachers' beliefs about argumentation can impact their classroom instruction and that students in low socioeconomic status (SES) schools are less likely to experience challenging science learning, there is…

Reform initiatives around the world are reconceptualising science education by stressing student engagement in science practices. Yet, science practices are language-intensive, requiring students to have strong receptive and productive language proficiencies. It is critical to address these rigorous language demands to ensure equitable learning…

Recent reform efforts in science education include a focus on science practices. Teachers require support in integrating these practices into instruction. Multimedia educative curriculum materials (MECMs), digital materials explicitly designed to support teacher learning, offer one potential resource for this critical need. Consequently, the…

Science education research, reform documents and standards include scientific argumentation as a key learning goal for students. The role of the teacher is essential for implementing argumentation in part because their beliefs about argumentation can impact whether and how this science practice is integrated into their classroom. In this study, we…

Despite being identified as an essential scientific practice, argumentation is rarely integrated into instruction. This could be influenced by teachers' pedagogical design capacity (PDC), which considers teaching as a design activity influenced by both instructional resources (such as tools and professional development (PD)) and teacher resources…

Recent education reform efforts have included an increasing push for school science to better mirror authentic scientific endeavor, including a focus on science practices. However, despite expectations that all students engage in these language-rich practices, little prior research has focused on how such opportunities will be created for…

The authors of this article, all of whom have been a part of this effort to assess argumentation in literacy-rich science curriculum, have struggled with our attempts to build 3 argument-related assessments--understanding, critiquing, and constructing arguments about scientific phenomena in both oral and written modes. Loosely affiliated with the…
