Purpose The authors are developing a model for rural science teacher professional development, building teacher expertise and collaboration and creating high-quality science lessons: technology-mediated lesson study (TMLS). Design/methodology/approach TMLS provided the means for geographically distributed teachers to collaborate, develop, implement and improve lessons. TMLS uses technology to capture lesson implementation and collaborate on lesson iterations. Findings This paper describes the seven steps of the TMLS process with examples, showing how teachers develop their content and pedagogical knowledge while building relationships. Originality/value The TMLS approach provides an innovative option for teachers to collaborate across distances and form strong, lasting relationships with others. 

This paper examines how practicing teachers approach and evaluate students’ critical thinking processes in science, using the implementation of an online, inquiry-based investigation in middle school classrooms as the context for teachers’ observations. Feedback and ratings from three samples of science teachers were analysed to determine how they valued and evaluated component processes of students’ critical thinking and how such processes were related to their instructional approaches and student outcomes. Drawing from an integrated view of teacher practice, results suggested that practicing science teachers readily observed and valued critical thinking processes that aligned to goal intentions focused on domain content and successful student thinking. These processes often manifested as components of effective scientific reasoning—for example, gathering evidence, analysing data, evaluating ideas, and developing strong arguments. However, teachers also expressed avoidance intentions related to student confusion and uncertainty before and after inquiry-based investigations designed for critical thinking. These findings highlight a potential disconnect between the benefits of productive student struggle for critical thinking as endorsed in the research on learning and science education and the meaning that teachers ascribe to such struggle as they seek to align their instructional practices to classroom challenges. 

Abstract Museums are local‐to‐global organizations operating in a digitized, distributed, and diverse 21st century world. Museums leaders face significant challenges in achieving broader relevance, meaningful engagement, and equitable outreach. This article examines the transformative potential of digitized collections to increase public engagement and enhance authentic educational efforts of museums, with specific emphasis on visual media as a key resource to achieve these outcomes. Using digitized collections to broaden learning opportunities and support a wide range of users will require museum leaders to engage in strategic digitization efforts—supplementing research images, making conscious decisions about meeting educational needs when setting digitization policies, and investing in meaningful outreach with digitized collections. Educational opportunities are contextualized with brief case studies of authentic investigations for middle school learners using digitized objects from a natural history museum. Three lessons learned during development and evaluation are described and implications for museum leaders are discussed.
