This article introduces an interview-based instrument that was created for the purposes of characterizing the visions of high-quality mathematics instruction of teachers, principals, mathematics coaches, and district leaders and tracking changes in those visions over time. The instrument models trajectories of perceptions of high-quality instruction along what have been identified in the literature as critical dimensions of mathematics classroom practice.

A key aspect of supporting teachers’ learning on a large scale concerns mathematics leaders’ practices in designing for and leading high-quality professional development. We report on a retrospective analysis of an initial design experiment aimed at supporting the learning of three math leaders who were charged with supporting the learning of middle-grades mathematics teachers across a large US school district.

The scarcity of efficient and user-friendly authoring tools has long been acknowledged as a limiting factor in the widespread development and deployment of intelligent tutoring systems (ITSs). Creating an effective authoring tool for domain experts poses two significant challenges: it must facilitate the creation of curricular content by domain experts who are typically neither ITS experts nor software engineers, and it must support the creation or modification of ITS-specific pedagogical strategies without exposing the complexity of the ITS itself to the domain expert.

Real-time formative assessment of student learning has become the subject of increasing attention. Students’ textual responses to short answer questions offer a rich source of data for formative assessment. However, automatically analyzing textual constructed responses poses significant computational challenges, and the difficulty of generating accurate assessments is exacerbated by the disfluencies that occur prominently in elementary students’ writing. With robust text analytics, there is the potential to accurately analyze students’ text responses and predict students’ future success.

Mining learner generated sketches holds significant potential for acquiring deep insight into learners’ mental models. Drawing has been shown to benefit both learning outcomes and engagement, and learners’ sketches offer a rich source of diagnostic information. Unfortunately, interpreting learners’ sketches—even sketches comprised of semantically grounded symbols—poses significant computational challenges.

This paper explores how robotics can be used as a new educational tool in a Montessori early education classroom. It presents a case study of one early educator’s experience of designing and implementing a robotics curriculum integrated with a social science unit in her mixed-age classroom. This teacher had no prior experience using robotics in the classroom beyond a three-day professional development workshop. The case study was constructed by collecting data from surveys, interviews, and a personal blog written by the teacher documenting her experience.

This paper employs meta-analysis to determine the influence of computer-based scaffolding characteristics and study and test scorequality on cognitive outcomes in science, technology, engineering, and mathematics education at the secondary, college, graduate, and adult levels.

Argumentation is central to instruction centered on socio-scientific issues (Sadler & Donnelly in International Journal of Science Education, 28(12), 1463–1488, 2006. doi:10.1080/09500690600708717). Teachers can play a big role in helping students engage in argumentation and solve authentic scientific problems. To do so, they need to learn one-to-one scaffolding—dynamic support to help students accomplish tasks that they could not complete unaided.
