One promising approach for connecting undergraduate content coursework to secondary teaching is using teacher-created representations of practice. Using these representations effectively requires seeing teachers' use of mathematical knowledge in and for teaching (MKT). We argue that Rowland's (2013) Knowledge Quartet for MKT, in particular, the…

Purpose: The paper aims to present a new two stage local causal learning algorithm -- HEISA. In the first stage, the algorithm discoveries the subset of features that better explains a target variable. During the second stage, computes the causal effect, using partial correlation, of each feature of the selected subset. Using this new algorithm,…

Students learn many concepts in the introductory statistics course, but even our most successful students end up with rigid, ritualized knowledge that does not transfer easily to new situations. In this article we describe our attempt to apply theories and findings from learning science to the design of a statistics course that aims to help…

In the resolution of problems in chemical kinetics and catalysis the mathematical models relate the independent variable that is usually time, with the dependent variable which is normally the concentration of a reactant. They conform to linear models, whose parameters such as the ordering to origin and the slope are kinetic parameters, applying…

The assessment of program functionality can generally be accomplished with straight-forward unit tests. However, assessing the design quality of a program is a much more difficult and nuanced problem. Design quality is an important consideration since it affects the readability and maintainability of programs. Assessing design quality and giving…

This contribution addresses the challenges brought on by the pandemic and argues that a forced acceleration in online teaching and assessment practices can become a sustainable model for the post-COVID-19 world. Technology is a great asset that provides learning opportunities for the whole community and the education sector should seek to adopt an…

Studies consistently show benefits of teacher-student race/ethnicity matching, with some suggestion that these effects are driven by role modeling. We explore this hypothesis by examining effects on the educational outcomes of Black and Hispanic students for exposure to same-race/ethnicity professional staff (e.g., administrators, counselors),…

Wlodarsky and Walters' study explored the reflective practices of college faculty, as they defined reflection and discussed processes, which they used to facilitate reflection on their professional development. A qualitative coding strategy was used, then an analytic concept mapping procedure described by Novak and Gowen (1984) was employed.…

We propose a novel model for learning environments to target the characteristics of digital natives and to improve informal learning practices, i.e. the exploration, discovery and self-monitoring of learning content and the reflection on learning activities. The Mobile Playful Learning Environment (MPLE) model is defined as consisting of seven…

Over 60 years of research reveal that informants who observe youth in clinically relevant contexts (e.g., home, school)--typically parents, teachers, and youth clients themselves--often hold discrepant views about that client's needs for mental health services (i.e., "informant discrepancies"). The last 10 years of research reveal that…

Cognitive diagnostic models can uncover students' mastery of multiple fine-grained skill attributes or problem-solving processes. A number of studies have applied cognitive diagnostic models to detect students' knowledge mastery in mathematics and language testing. However, few studies focus on cognitive diagnostic assessment in K-12 science…

Representations have been widely applied to teaching and learning in Western classrooms and recently in several Asian countries. More and more Asian schools are calling for the application of this approach in teaching science. However, little has been known about how the construction of representations could enable teachers to make changes in…

This study demonstrates a leadership professional development (PD) with a goal to build a coalition for attracting and retaining a diverse STEM teaching workforce in K-12 schools. In 2019, 111 participants of 21 teams from across the US participated in the leadership PD. Each team was comprised of 5-6 teachers and administrators representing their…

The purpose of this qualitative study was to investigate the inequities that exist for Latinas in obtaining leadership positions within education, and how Latina leaders respond to said inequities within urban Mid-Atlantic school districts. The findings of this study may help advise district leaders on what improvements and enhancements to make in…

Purpose: The purpose of this paper is to explore the merits of lesson study (LS) as a research approach for research in (science) education. A lesson was developed to introduce students to model-based reasoning: a higher order thinking skill that is seen as one of the major reasoning strategies in science. Design/methodology/approach: Participants…
