The paper presents findings from a study that examined, through the lens of the Image Having layer of the Pirie-Kieren model, the qualitative characteristics of the images that different children formed when engaging with eight, novel partitive quotient tasks. The Image Having layer is the first point of abstraction within the Pirie-Kieren model.…

The intention of the study was to examine the effects of a fraction intervention in a whole-class environment. The intervention aimed to enhance students' conceptual fraction knowledge, with a major focus on fraction magnitude understanding. This study included 120 fifth-grade students in standard classroom settings. Utilizing a cluster randomized…

Background: The present study delves into the debate surrounding the effectiveness of homework, focusing specifically on the use of online homework in teaching decimal numbers to 5th and 6th grade primary school students. It highlights the challenges students face in representing and identifying decimal numbers, a concept that is often difficult…

This dissertation examines students' social-emotional experience with knowledge building pedagogy from the lenses of grit and growth mindset. The goal of this dissertation is to understand how interest, perseverance of effort and growth mindset oriented feedback engage students social emotionally in knowledge building to sustain and deepen their…

This research investigated the impact of a professional development program on enhancing fifth-grade environmental science teacher efficacy through place-based education (PBE) practices--the Meaningful Watershed Educational Experiences (MWEE) Professional Development Training aimed to promote teacher engagement and increase pedagogical content…

This paper presents findings from a study that examined the strategies that children, who had only been taught the part-whole fraction sub-construct at school, used for finding the fraction associated with solving varied partitive quotient problems. A qualitative, microgenetic research design was used involving nine year 5 (aged 9-10) children…

Instructional time spent on elementary social studies is often marginalized due to the emphasis placed on other content areas. Therefore, social studies teachers must employ meaningful instructional strategies that will engage students while promoting content acquisition. This quasi-experimental study responds to this challenge by guiding a sample…

In the research reported in this paper, using a modified version of the interconnected model of teacher professional growth (IMTPG) proposed by Clarke and Hollingsworth (Teaching Teacher Educ 18:947-967, 2002), we aimed to understand the learning dynamics in a lesson study of a group of five teachers of grades 5-6, during their work around…

Attending to the whole unit that a number refers to in a mathematical problem situation and showing flexibility in coordinating different units are foundational for mathematical understanding. In this study, we explored teachers' attention to and flexibility with referent units in situations involving fractions and fraction multiplication. Using…

Sustainability consciousness is an outcome of Education for Sustainable Development, which was launched by UNESCO in 2014 to create a society with sustainable living behavior. The purpose of this research is to analyze the impact of the RADEC learning model oriented ESD on students' sustainability consciousness. This research involved 150…

This paper investigates in-service intermediate phase mathematics teachers' metacognitive awareness based on their engagement in a professional development intervention in two rural and one township school in South Africa. Professional teacher development interventions should be structured and collaborative as teachers tend to revert to…

We present the evolving fraction conceptions of two elementary school children with mathematics learning disabilities (MLD). We use qualitative analyses to capture the mathematical knowledge and experiences of each child and show how teaching was used to support advancement of their fractional reasoning. Results illustrate two viable pathways of…

The use of open problem-solving tasks in mathematics education challenges teachers' beliefs, knowledge and practices. This article examines the practices of two primary teachers and their 3rd to 5th grade classes during a three-year in-service teacher training project aiming to increase mathematical problem-solving in class. Three lesson videos…

A learning format gaining attention that encourages language acquisition in science is the use of dynamic models as instructional tools. This grounded theory investigates the impact of the dynamic food chain model as an alternative lesson for teaching food chains. The researchers examined the impact of a paper-based activity and a dynamic model…

This study explores the dimensionality of mathematical knowledge needed by elementary school teachers. Specifically, we focus on the construct of Mathematical Knowledge for Teaching to investigate whether common mathematical content knowledge (the generic mathematical knowledge that is held by an educated adult), specialized content knowledge (the…
