The aim in the current study is to examine the conceptualizations of zero in arithmetic operations among students with learning disabilities (LD) and no learning disabilities (N-LD). The similarities and differences in the understandings of students with LD and N-LD of zero in arithmetical operations will be discussed. The study is a multiple case…

This study examined the change in the two groups of senior primary school students' understanding of particulate nature of matter (PNM) before and after each group involved in related instructions, namely inquiry instruction with multiple representations (IIMR) and regular instruction (RI). Data were collected through a two-tier questionnaire, and…

This study aimed to examine the effectiveness of the semantic concept map method in teaching the family concepts of life studies lessons to students with Autism Spectrum Disorder. A multiple probe model with probe phase between subjects, one of the single-subject research methods, was used. The subjects of the study are 10-year-old three boys…

The aim of the study is to improve students' nature of science understandings while integrating nature of science aspects into appropriate science-technology-engineering-mathematics (STEM) activities. In this study, four STEM-based contextualized nature of science activities are developed during the 4 weeks study. The sample of this study consists…

This study aims to investigate the effect of guided inquiry-based learning approach on conceptual change and durability of sixth-grade middle school students regarding density concept.

Process Oriented Guided Inquiry Learning (POGIL®) as a collaborative inquiry method has been widely used in teaching chemistry to high school and college students. This paper presents the impact of POGIL on 65 middle school students' understanding about nature of matter. It is a quasi-experimental non-equivalent control group design study in which…

Concrete manipulatives and dynamic geometry software (DGS) are both commonly used for geometry education in elementary and middle schools. This study sets out to understand which of the two approaches was better in improving the conceptual understanding of quadrilaterals for fifth graders. A pre-/post-test design was conducted in which the same…
