Textbooks play an important part in teaching and learning mathematics. However, textbook research on spatial ability has so far received little attention. In this study, we investigated whether school mathematics textbooks provide enough opportunities for primary students to learn three-dimensional shapes and help them acquire spatial ability.…

Reasoning about organic chemistry reaction mechanisms requires engagement with multiple concepts and necessitates balancing the relative influence of different chemical properties. A goal of organic chemistry instruction is to support students with engaging in this type of reasoning. In this study, we describe our use of case comparison problems…

The concept of sustainability includes many different definitions and diversified perspectives with its ecological, economic, social, and cultural dimensions. However, building positive attitudes towards sustainability is important to fulfill broad and comprehensive sustainability goals. The present study aimed to determine the meanings that…

An increasing number of studies have explored the process of how subjects solve problems through remote association. Most research has investigated the relationship between an individual's response to semantic search during the think-aloud operation and the individual's reply performance. Few studies, however, have examined the process of…

In this paper we present the results of a survey of research studies on the learning of multivariable calculus in a wide geographic spectrum. The goal of this study is to describe what research results tell us about students' learning of calculus of two-variable functions, and how they inform its teaching. In spite of the diversity of cultures and…

This article aims to investigate the teaching of chance in the context of tactile models (TM) from the perspective of the Theory of Register of Semiotic Representations. In this qualitative research, we sought to identify the different types of semiotic registers and transformations (treatment and conversion), in the solutions of the tasks of the…

This research focuses on students' higher-order cognitive skill (HOCS)-oriented learning to construct effective hierarchical thinking abilities in their chemical particulate nature of matter. For in-depth knowledge and profound understanding, this research deals with students' positive developments towards HOCS with a special guidance to Marzanos'…

In this study, the researchers (i) determined the perception levels of candidate teachers about Specific Learning Difficulties (SLD) using Online Photovoice (OPV) methodology, (ii) shared the research results with relevant researchers and practitioners in order to contribute to increase the knowledge level of candidate teachers about SLD, and…

Rapidly occurring advancements in molecular genetics, such as recent developments in epigenetics, are challenging traditional genetics as it is taught at schools. For example, the adoption of epigenetics--which provides molecular mechanisms for the environment to directly alter phenotypic variation--would mean that pivotal tenets in genetics…

According to National Council of Teachers of Mathematics (NCTM), students must develop a conceptual understanding of place value by second grade to understand that mathematics processes are more than a set of procedural steps. Yet, students with learning disabilities in mathematics typically struggle to understand place value in a deeper,…

Evolution is an essential underlying concept in biology. Previous research demonstrates that many obstacles exist that prevent successful teaching and learning about evolution. This research study used the theoretical framework of cultural border crossing and its underlying cognitive explanation, collateral learning, to design an intervention for…

The aim of this study is to obtain information about students' definitions, mistakes, misconceptions, and van Hiele geometry thinking levels by using the definitions of 4th grade students for geometric shapes of rectangle, square, isosceles triangle, equilateral triangle, and scalene triangle. The study was carried out with 156 primary school 4th…

For food research, control, and production, valid and trustworthy analytical data are important. Our practical chemical food safety course for engineers therefore uses real-life studies for the ease of understanding the concept and the needed requirements for high analytical quality in relation to enabling correct evaluation of chemical food…

Cartoons are undoubtedly the TV programmes children most prefer watching. This study uses cartoons -- which have significant effects on children's learning -- for concept teaching. Within the scope of the study, four cartoons were developed for teaching position-related concepts (in-out, in front of-behind, under-above) pre-school teachers noted…

Using a randomized controlled trial, we examined the effect of a fractions intervention for students experiencing mathematical difficulties in Grade 5. Students who were eligible for the study (n = 205) were randomly assigned to intervention and comparison conditions, blocked by teacher. The intervention used systematic, explicit instruction and…
