This project seeks to understand the emergence of mathematical meanings mediated by learners' interactions with multiple artifacts. Extending our prior work which took an enactivist approach and revealed the dynamics of embodied interactions fundamental to understanding fraction division, we now employ a semiotic lens to illuminate how learners…

This paper examines two activities in a weeklong Professional Development (PD) focused on implementing mathematical play in kindergarten classrooms. Though the weekly activities all had different goals, the two focal activities (Pattern Blocks and Create-a-Monster) were designed specifically to be both playful and mathematically engaging for the…

This paper presents Big Ideas of Measurement as a framework of students' thinking about measurement. Drawing from research-based evidence, the framework is a collection of key concepts that students must develop for a robust understanding of measurement and, as such, are key aspects of students' thinking teachers should learn to notice. In a case…

Immersive spatial diagrams (three-dimensional diagrams rendered with immersive stereoscopic displays) offer learners the opportunity to extend practices of diagramming in school geometry into a human-scale, spatial context. Learners can use two or more hands to inscribe simultaneously with digital spatial painting tools, a spatial analog of the…

To promote scientific literacy in school science, students need to learn key concepts in science, along with the nature of scientific knowledge and how it is generated. Ideally, this learning mirrors authentic scientific inquiry through student engagement in three key epistemic practices: flexibility and creativity, knowledge construction, and…

Procrastination is one of the issues affecting more than half of the student population and is known to impact them negatively. It is also one of the major reasons for failure and dropout. Therefore, several studies have been conducted in this domain to understand when and why students procrastinate. The existing studies use self-reported…

As K-12 educators work toward targeted, small group instruction together with college and career readiness skills, many implement collaborative learning experiences within their classrooms. Collaborative learning can help students develop deeper understandings of content while building critical life-long skills, and using a design for learning…

Emerging literature has highlighted the importance of discerning general and strategic organizational context (OC) factors (e.g., leadership and climate) and their interaction effect on individual implementation behaviors (e.g., attitudes toward evidence-based practices; EBPs) in youth mental healthcare. This study aimed to examine how leadership…

In this paper duality between real world phenomenon and mathematics will be discussed. This duality exists for many years which considerably remarked in the history of mathematics curriculum. One of the good potential for filling the gap between real world phenomenon and mathematical ideas would be modelling tasks which require performing the…

This practitioner paper explores the positive impact playwork could have for Australian OSHC (Outside School Hours Care) environments and in turn, educators and children. Through a discussion of four theoretical perspectives pertaining to physical space from a playworkers perspective, the authors show how developing a conceptual understanding of…

This study aimed to translate, adapt linguistically and culturally, and validate the Portuguese version of the Children's Assessment of Participation and Enjoyment/Preferences for Activities of Children (CAPE/PAC). CAPE/PAC is a tool that measures the participation of children and youth with and without disabilities in leisure activities,…

Organic chemistry is notorious for being difficult to learn. Herein we describe a two-pronged approach to engage students in the ability to afford successful knowledge building. We have drawn on focus group interviews with students to show that the approach is appreciated by the students. The two prongs comprise peer learning in small groups and…

The activity presented here is about an approximate or order-of-magnitude approach to information technology on the nano level, dealing in particular with the genetic code. Based on "There's Plenty of Room at the Bottom", the famous and visionary paper by Richard Feynman, the activity provides insight into a core concept of nanoscience…

The COVID-19 pandemic has significantly affected teaching processes worldwide, particularly in laboratory-intensive courses. To adapt, online experiments have been implemented globally. In response, educators at the Department of Chemistry, Chulalongkorn University, developed a Lab@Home chemistry experiment for their general chemistry lab course…

The aim of this study was to explore how landmark-based STEAM projects can be created to run cross-country math trails utilizing augmented reality and 3D printing technologies. A study was conducted involving 42 prospective teachers at a teacher education institution. We organized a series of lectures in a spatial geometry course and explored…
