Authoring tools for Intelligent Tutoring System (ITS) have been shown to decrease the amount of time that it takes to develop an ITS. However, most of these tools currently do not extend to collaborative ITSs. In this paper, we illustrate an extension to the Cognitive Tutor Authoring Tools (CTAT) to allow for development of collaborative ITSs that…

The links between the mathematical and cognitive models that interact during problem solving are explored with the purpose of developing a reference framework for designing problem-posing tasks. When the process of solving is a successful one, a solver successively changes his/her cognitive stances related to the problem via transformations that…

Children with learning disabilities can be as sharp as their peers; however, they may find it challenging to write, read, reason out information, spell things correctly, or process information. Due to this, it is critical for students to understand the ways of learning that suit them the best. They may not be aware of the different ways they can…

We explore whether the use of assistive technology allows teachers and children to negotiate shared understandings for learning science and language. We understand our afterschool sessions as critical encounters. Artifacts used in the encounters enabled transcending of the tensions and became drivers for learning. In the studied 13 encounters,…

With the goal of achieving bilingualism and biculturalism, dual language education (DL) has a social justice orientation. As the program option with the best track record of closing the achievement gap between Latinx and White students, DL programs can potentially create environments in which learners can develop knowledge of science, technology,…

Since the foundation of the Khan Academy (2006), a great deal of attention has been generated to the term "flipped classrooms" (also known as "reverse" or "backwards" classrooms), which is a (new) pedagogical movement that reverses the traditional paradigm of class lecture and homework. This approach subordinates…

"Thinking like a lawyer" is traditionally associated with rational-analytical problem solving and an adversarial approach to conflict. These features have been correlated with problems of psychological, or emotional, distress amongst lawyers and law students. These problems provide a strong argument for incorporating a consideration of…

A major area of concern in academia is that of student retention at the university, college, and departmental levels. As academics, there is a considerable amount that we can do to improve student retention, and reduce the attrition rates in our departments. One way to solve this is to take an innovative approach in the classroom to enhance the…

The article reports the results of a longitudinal research study conducted in three mathematics classes in Czech schools with 62 pupils aged 12-18 years. The pupils were exposed to the use of selected heuristic strategies in mathematical problem solving for a period of 16 months. This was done through solving problems where the solution was the…

In this study, we investigated teachers' teaching practices and their underlying beliefs regarding context-based tasks to find a possible explanation for students' difficulties with these tasks. The research started by surveying 27 Junior High School teachers from seven schools in Indonesia through a written questionnaire. Then, to further examine…

Problem solving is often challenging for students because they do not understand the problem-solving process (PSP). This study presents a three-stage, context-based, problem-solving, learning activity that involves watching detective films, constructing a context-simulation activity, and introducing a project design to enable students to construct…

The aim of this study was to investigate the pre-service teachers' perceptions into learning primary school science using the method of Problem Based Learning (PBL). This learning strategy has been introduced into the B.Ed. programme at the University of Trinidad and Tobago for pre-service teachers who are expected to implement it in their…

A teaching experiment-using Mathematica to investigate the convergence of sequence of functions visually as a sequence of objects (graphs) converging onto a fixed object (the graph of the limit function)-is here used to analyze how the approach can support the dynamic blending of visual and symbolic representations that has the potential to lead…

Surface-enhanced Raman scattering (SERS) studies of art represent an attractive way to introduce undergraduate students to concepts in nanoscience, vibrational spectroscopy, and instrumental analysis. Here, we present an undergraduate analytical or physical chemistry laboratory wherein a combination of normal Raman and SERS spectroscopy is used to…

In this article, we analyze a first grade classroom episode and individual interviews with students who participated in that classroom event to provide evidence of the variety of understandings about variable and variable notation held by first grade children approximately six years of age. Our findings illustrate that given the opportunity,…
