The current study examined teacher classroom responses to the Classroom Strategies Coaching (CSC) Model in 14 high-poverty elementary schools. Coaches used observational data to identify practice needs, goals, and monitor progress regarding instructional and behavioral management strategies. The sample included 53 teachers that received the CSC…

The evidence continuum is a five-domain model for building evidence through needs assessment, program theory, process evaluation, outcomes and impact evaluation, and optimization studies. In this conceptual article, the first two domains of the evidence continuum are used to design a learner centered course on advanced research methods, and…

Understanding fraction magnitudes is foundational for later math achievement. To represent a fraction "x/y," children are often taught to use "partitioning": break the whole into "y" parts, and shade in "x" parts. Past research has shown that partitioning on number lines supports children's fraction…

Understanding fraction magnitudes is foundational for later math achievement. To represent a fraction x/y, children are often taught to use "partitioning": Break the whole into y parts and shade in x parts. Past research has shown that partitioning on number lines supports children's fraction magnitude knowledge more than partitioning on…

This paper explores the role of exemplarity in education through a conceptualisation of two different dimensions of exemplarity in educational practice. (1) Pedagogical exemplarity, which relates to the pedagogical and ethical dimension of educational practice. In other words, this dimension explores the educational moments when…

A flexible and modular peptide modeling set was designed using freely available software tools. The set consists of space-filling models of all 20 naturally occurring amino acid side chains and a modular kit for constructing peptides employing C-alpha carbons and amide bond groups. Connectors that allow free rotation about phi and psi angles on…

The guiding question of this article is to what extent, if any, Chikuro Hiroike's (1866-1938) tenets about so-called ortholinons (as moral exemplars), in his general system of moralogy, illuminate problems typically attributed to moral-exemplar methodology and help with their amelioration. I begin with a brief rehearsal of the method of using…

This paper reports a systematic literature review of the balance model, an often-used aid to teach linear equations. The purpose of the review was to report "why" such a model is used, "what" types of models are used, and "when" they are used. In total, 34 peer-reviewed journal articles were analyzed, resulting in a…

This paper presents the results of a literature review focusing on the use and potential of Fermi problems (FPs) in the STEM disciplines. We identify different usages and roles given to FPs in each of the STEM disciplines and highlight their potential to promote modeling of real phenomena and situations as well as learning about the estimation of…

Single-type, 8-fold-grooved, commercially accessible interlocking disks (ILDs) have been used for modeling of complex polyhedral and reticular topologies with relevance to inorganic and hybrid materials. The assembly of complex topologies relies on the preparation of secondary building units (SBUs), which exhibit different connectivity than that…

Bourdieu's career long endeavour was to devise both theoretical and methodological tools that could apprehend and explain the social world and its mechanisms of cultural (re)production and related forms of domination. Amongst the several key concepts developed by Bourdieu, habitus has gained prominence as both a research lens and a research…

This paper investigated the integration of a Lesson Study Model (LSM) into distance STEM education during the COVID-19 pandemic. The study focused on six dimensions: (1) STEM education in distance learning, (2) Lesson Study (LS), (3) lesson planning processes, (4) challenges of lesson planning, (5) evaluation and assessment methods, and (6)…

Research using the Anthropological Theory of the Didactic suggests different models of how student learning may evolve in the progression of undergraduate mathematics coursework: from elementary courses in Calculus to more advanced courses in Analysis. An ideal model suggests that the theory-driven learning in the latter serves as a natural…

In the research reported in this paper, using a modified version of the interconnected model of teacher professional growth (IMTPG) proposed by Clarke and Hollingsworth (Teaching Teacher Educ 18:947-967, 2002), we aimed to understand the learning dynamics in a lesson study of a group of five teachers of grades 5-6, during their work around…

A central goal of introductory physics for the life sciences (IPLS) is to prepare students to use physics to model and analyze biological situations, a skill of increasing importance for their future studies and careers. Here we report our findings on life science students' ability to carry out a sophisticated biological modeling task at the end…
