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…

Every branch of science needs visitors' attention during the poster presentation session at conferences, symposiums, seminars, etc. In particular, participants in the chemistry and biochemistry conference need more visual tools to explain their research work in detail. Presence of smartphones and the ability of 2D barcodes will allow chemical…

This paper uses evidence-centered assessment design (ECD) to structure and analyze a laboratory activity where students collect and represent titration curve data to determine acid strength in terms of molarity and dissociation constant. Following principles of multidimensional learning, the activity prompts students to demonstrate knowledge of…

In this paper, we propose an elementary proof of Niven's Theorem in which the tangent function will have a primary role.

In statistical inference, importance of sampling is recognized as one of its key concepts, which has allowed its incorporation internationally in different curricular guidelines and specifically in the Chilean curriculum, since the first notions of sampling are introduced in 7th Grade. This paper presents an analysis of the responses to an…

The aim of the study is to teach the concept of function using cryptology and to investigate whether it provides support to students who have difficulty integrating this topic into everyday life. The study's research group consisted of 50 elementary school teachers in the department of mathematics education at a public college in Ankara. Since the…

We developed new teaching materials, electrical resistors and capacitors, using carbon nanotube (CNT) paper and carbon fibre (CF) paper to foster students' creative thinking, thereby deepening and extending learning. Using a CNT-paper electrical resistor, it is possible to elucidate the dependence of the resistance value on the length and width.…

Perception of change and continuity and perception of time and chronology are among the skills expected to be acquired by students through the Social Studies course curriculum (SSCEC). These skills are included in the SSCEC, which was updated in both 2005 and 2018. It is aimed to attainment, develop and transfer these skills to students by making…

In science learning, the experiment is an essential activity to facilitate students to discover and develop knowledge as well as to enhance scientific process skills and self-confidence. This study aims to create a simple experimental apparatus related to the principle of fluid continuity that can be made and conducted by the teacher and student…

In this paper, differences in the implementation of a number activity called the snake game are studied. Nine Swedish preschool teachers worked in collaboration with a research team, enacting the same activity with their groups of 5-year-old children over a 3-month period. Variation theory forms the basis for the analysis of 67 videorecorded…
