Disciplinary Content Knowledge

Bioinformatics—a rapidly developing discipline that integrates mathematical and computational techniques with biological knowledge for applications in medicine, the environment, and other important aspects of life—is an example of an emerging field that illustrates the need for a greater focus on STEM integration in K12 education. Studies on teaching bioinformatics in high school reveal difficulties that arise from a lack of curricular resources and teacher knowledge to effectively integrate disciplinary content. In this study, we investigated challenges teachers experienced in teaching a problem-based bioinformatics unit after participating in professional development (PD) activities that were carefully constructed using research-based effective PD characteristics.

The Socioscientific Issues Teaching and Learning (SSI-TL) framework is a guide for developing an instructional approach to learning experiences focused on socioscientific issues (SSI). Despite the potential benefits of SSI learning, teachers often struggle to implement this approach in their classrooms, and one of the most prominent reasons for this struggle is science teacher concerns and hesitation associated with incorporating social dimensions of the issues into their instruction. The purpose of this article is to provide science teacher educators with tools to help teachers better manage the integration of the social dimensions of SSI in issues-based teaching.

Problem solving is a central focus of mathematics teaching and learning. If teachers are expected to support students' problem-solving development, then it reasons that teachers should also be able to solve problems aligned to grade level content standards. The purpose of this validation study is twofold: (1) to present evidence supporting the use of the Problem Solving Measures Grades 3–5 with preservice teachers (PSTs), and (2) to examine PSTs' abilities to solve problems aligned to grades 3–5 academic content standards.

Teachers face challenges when building the concept of substance with students because tensions of meanings emerge from students’ daily life and canonical ideas developed in classrooms. A powerful tool to address learning, pedagogical, and research challenges is the conceptual profile theory. According to this theory, people employ various ways of conceptualizing the world to signify experiences. Conceptual profiles are models of the heterogeneity of modes of thinking and speaking about a given scientific concept which are used in a variety of contexts. To better understand the heterogeneity of thinking/speaking about substance, the present study aimed to answer: (1) What are the zones that constitute the conceptual profile of substance?; and (2) What ways of thinking and speaking about substance do teachers and students exhibit when engaged in a classroom formative assessment activity?

In this paper, we share the design and impact of a set of two-hour online mathematics professional development modules adapted from face-to-face video-based materials.

Researchers have typically identified and characterized teachers’ knowledge bases (e.g., pedagogical content knowledge and subject matter knowledge) in an effort to improve enacted instructional strategies. As shown by the Refined Consensus Model (RCM), understanding teacher learning, beliefs, and practices is predicated on the interconnections of such knowledge bases. However, lesson planning (defined as the transformation of subject matter knowledge to enacted pedagogical content knowledge) remains underexplored despite its central position in the RCM. We aim to address this gap by developing a conceptual framework known as Pedagogical Chemistry Sensemaking (PedChemSense).
