Gross anatomy courses utilize cadaver dissection to teach identification, topography, and spatial relationships of organs. The deconstructive nature of dissection, however, focuses students' attention on the "big picture", followed by a discovery of details. This approach may be useful for many, however some students may prefer to…

Manipulative-based instructional sequences have proven to be successful with students with disabilities. However, instruction must not only support the acquisition of conceptual and procedural knowledge but also build on students' strengths. This article describes how teachers can use manipulative-based instructional sequences to support the…

The COVID-19 pandemic affected a large range of in-person education activities in Colombia. This created great limitations in academic performance for students with reduced access to communication technologies and deepened the educational gaps in the country. This was particularly true for sciences such as biochemistry. In Colombia, molecular…

To understand the ways that manipulatives might support changes in students' reasoning about algebraic generalizations, a constructivist teaching experiment was conducted with two sixth-grade students. The students interpreted numerical situations with units of one and could construct units of units in mental activity. Initially, the students'…

Making connections between children's existing means of expression (play, art, and movement) and the intricacies of print is a necessary and time-honored approach to writing instruction in the early years of school, yet, after kindergarten, one that is easily overlooked. In this article, we examine an approach to writing instruction for…

Kindergartners' math skills predict later academic outcomes. However, we know little about kindergarten mathematics instruction. Using data from 182 classroom observations in a large urban district, we explore time spent on mathematics and math content coverage. We also examine two underinvestigated aspects of kindergarten math instruction: (1)…

The diversity of scientific methods has received widespread attention and recognition in recent years. Brandon's Matrix illustrated four categories of scientific methods, which was applied to establish the analytical framework of this study. This paper adopted content analysis to investigate how the diversity of scientific methods is represented…

Many approaches to teaching Newman projections and conformational manipulation rely on lecturing using only two-dimensional representations. While molecular models are recognized as useful learning tools, students are often left to figure out how to use them during the initial learning process. The availability of basic online molecular models…

Despite the many benefits of play, within primary school, play is often reduced to lunch breaks, particularly as children move to higher grades. Loose parts play affords children opportunities to develop imagination and 21st-century skills (collaboration, communication, creativity and critical thinking). As part of a larger project, two Year 4…

This study investigates the integration of computational thinking (CT) into early elementary literacy, focusing on kindergarten to second grade students, using multiple representations to understand their ideas of CT. Through clinical task-based interviews with 12 students, we found that concrete manipulatives, pictorial/graphical representations,…
