This article presents a framework for understanding historical perspective taking (HPT), the effort to use historical material to explore the internal states of past people. It addresses gaps in HPT research by (a) linking HPT to theories and research from the social science disciplines on perspective taking and the self and (b) proposing a way to…

We question widely accepted practices of publishing articles that present quantified analyses of qualitative data. First, articles are often published that provide only very brief excerpts of the qualitative data themselves to illustrate the coding scheme, tacitly or explicitly treating the coding results as data. Second, articles are often…

We investigated what a cognitive framework for measuring classroom teaching could reveal about (a) the impact of a professional development (PD) program on teaching practices and (b) the relationship between teaching practices and student science learning. To conduct this study, we leveraged a collaboration between two entirely independent…

How do children begin to make the transition from seeing the natural world to scientifically observing the natural world? This study explored how differences in parent conversational strategies and disciplinary knowledge impact children's experience observing biological phenomena during shared informal learning. A total of 79 parent-child pairs…

Recent science educational policy reform efforts call for a shift toward practice-focused instruction in kindergarten-Grade 12 science education. We argue that this focus on engaging students in epistemic practices of science opens up new possibilities for the design of learning environments that support the stabilization of learners'…

How does deep conceptual change occur when students play well-designed educational games? To answer this question, we present a case study in the form of a microgenetic analysis of a student's processes of knowledge construction as he played a conceptually-integrated digital game (SURGE Next) designed to support learning about Newtonian mechanics.…

This article reports on a study in which activity theory was used to design, implement, and analyze a 10-week curriculum unit about how honeybees collect nectar with a particular focus on complex systems concepts. Students (n = 42) in a multi-year kindergarten and 1st-grade classroom participated in this study as part of their 10 regular classroom…

Responsive teaching occurs when teachers take up and "respond" to their students' ideas during instruction (J. L. Pierson, 2008). Although responsive teaching is gaining recognition as an effective strategy for encouraging student learning, few methods of analysis are capable of characterizing the different ways in which teachers take up…

This case study examines the role of playful talk in negotiating the "how" of collaborative group work in a 6th-grade science classroom. Here we develop and test a Vygotsky-derived hypothesis that postulates playful talk as a mechanism for identity exploration and group status negotiation. Our findings indicate that students utilized the…

We present a new method for analyzing a student's learning over time for a specific skill: analysis of the graph of the student's moment-by-moment learning over time. Moment-by-moment learning is calculated using a data-mined model that assesses the probability that a student learned a skill or concept at a specific time during learning (Baker,…

New high-frequency, automated data collection and analysis algorithms could offer new insights into complex learning processes, especially for tasks in which students have opportunities to generate unique open-ended artifacts such as computer programs. These approaches should be particularly useful because the need for scalable project-based and…

We present a method for assessing science inquiry performance, specifically for the inquiry skill of designing and conducting experiments, using educational data mining on students' log data from online microworlds in the Inq-ITS system (Inquiry Intelligent Tutoring System; www.inq-its.org). In our approach, we use a 2-step process: First we use…

This study investigates the ongoing debate in the conceptual change literature between unitary and elemental perspectives on students' knowledge structure coherence. More specifically, the current study explores two potential explanations for the conflicting results reported by Ioannides and Vosniadou (2002)and diSessa, Gillespie, and Esterly…

There is a growing national recognition that teachers and teaching are at the heart of successful educational reform. However, few tools exist for measuring classroom instruction. The primary purpose of this article is to describe methods we developed to measure and study teaching, specifically while teachers were using a multimedia intervention…
