Single-type, 6-fold symmetrically grooved, and commercially accessible interlocking disks (ILDs) have been used for modeling of sp[superscript 2] hybridized carbon-based nanoarchitectures and complex polyhedral and reticular material models. In the case of the carbon-based nanoarchitectures, we showcase that the primary ILDs can be directly used…

In this paper a "non-elementary system" is defined as a system consisting of elementary (i.e., indivisible) constituents. Such systems are a common feature of the standard model of particle physics: for example, according to the standard model, a proton (non-elementary particle) consists of two up quarks and one down quark (elementary…

The document presents a set of categories for the analysis of the conceptualization of the congruence of polygons--a central theme in school mathematics--and details the application of the analytical tools used, derived from Grounded Theory, in this construction. This set of categories is called 'Interpretive Model of the Conceptualization of…

We use number sense in our daily lives to make decisions about quantities. This number sense is connected to our mental number line, in which we draw on our understanding of physical number lines. We often use number lines in the elementary grades for counting and to represent mathematical operations, such as addition and subtraction. Such tasks…

This article highlights how the Mathematics Teaching Practice of "facilitating meaningful mathematical discourse" (NCTM 2014, p. 10) was used to support a class of eighth-grade students as they engaged in recognizing patterns in which inputs are related to an output. As Carpenter, Franke, and Levi (2003) recommended, the authors chose…

This study aims to analyze the views of children whose spatial concept development is supported by activities conducted with educational cartoons compared to traditional methods. In this context, preschool children's views on the activities, their memory retention of them, and the levels of awareness caused by the activities were investigated.…

This paper introduces quantum materials and the notion of using models to aid the comprehension of complex ideas. It describes a hands-on activity, collaboratively developed by scientists and artists, that promotes an understanding of how experts take advantage of analogical thinking and model building to develop important frameworks. Quantum…

Difficulties in understanding evolution are often rooted in early childhood, arising from naïve assumptions and cognitive biases. However, literature reviews mainly focus on school and university students' understanding of evolution, with only limited comprehensive reviews on children in early childhood aged up to 7 years. This systematic review…

The achievement of a proper conceptual change is a challenge for students since there are some constraint-based interactions including different ontological categories with the well-known dichotomy of matter or process. To mitigate this state of affairs, more instructional sequences with pedagogical approaches are needed because many students,…

This research, which was conducted in order to reveal the cognitive structures of high school students regarding the concept of energy through the word association test, was designed in a survey model. Word association test was used as a data collection tool. After the necessary information was given to the students, they were given three minutes…

This study aimed to examine the applicability of citizenship education - one of the main objectives of social studies education- in early childhood, considering the opinions of preschool teachers. The study used a case study design, involving a sample group of twenty-four preschool teachers. The data were gathered using semi structured interview…

Coeditors of a special issue of the "American Annals of the Deaf" on mathematics instruction in deaf education, the authors provide a context for the five featured articles. First, the authors establish the importance of mathematics. They then give a historical account of previously related "stepping-stones." Beginning at 1990,…

Enzymes are widely applied in different industries, like pharmaceutical, food, biofuel, and waste valorization. However, the enzyme operating conditions are very limited. So, in most industrial processes, enzymes are not efficient, due to the use of harsh conditions, like organic solvents, extreme pH, and temperature. Immobilization arises as a…

Recent voices in creativity research emphasize the vital role that processes of active engagement and interaction play. These distributed, interactivity-based, and ecological accounts critique the reduction of creativity to mental mechanisms and eschew the methodological individualism that underlies this view. Instead, they elevate socio-material…

The study examines how students in Grade 9 handle conceptual knowledge through the concept of continuity and change in the context of large-scale assessment. The research questions address: (1) what strategies the students use when they use the two parts of the concept concomitantly; and (2) any gender-related differences regarding these…
