Background/purpose: This study aimed to identify the impact of teaching science based on John Zahorek's model on the acquisition of scientific concepts among seventh-grade female students. Materials/methods. It was based on the quasi-experimental method. The study participants, comprising 58 seventh-grade students, were intentionally selected from…

Mathematical modeling tasks can engage students in ways in which they see themselves as mathematicians capable of using mathematics to solve real-world and complex problems. As mathematics teacher educators and researchers, the authors collaborated with two 5th-grade teachers, Liz and Anna (pseudonyms), focusing on equitable practices that foster…

The importance of introducing students to mechanistic reasoning (MR) early in their schooling is emphasised in research. The goal of this case study was to contribute with knowledge on how early primary students' (9-10 year-olds) MR in chemistry is expressed and developed in a classroom practice framed by model-based inquiry. The study focuses on…

Developmental Education in Mathematics (DEM) according to Zankov's model, or "Russian mathematics", has been in use in Norway since 2009 in an increasing number of schools (about 100 elementary schools in 2024). There has been relatively little research into the implementation of this teaching method in a Norwegian context. In this…

In the digital age, enhancing digital literacy among prospective primary school teachers is crucial for effective education. The purpose of this study is to evaluate how well RADEC's digital learning paradigm improves digital literacy skills compared to traditional training. The study involved 100 students from two institutions and used a…

This paper considers the teachings of spatial thinking in two Danish school interventions with children, ages 10-13 (2018-2021), by turning Lefebvre's spatial triad into a research-based exercise. Based on children's responses, this paper concludes that, first, by allowing children to include their own spatial experiences, they can resonate with…

This study aimed to explore what kinds of epistemological messages were conveyed through teacher discourse in modeling-based and traditional elementary science classrooms and how teachers framed the two classrooms distinctively through these messages. Data came from two sixth-grade teachers' science classrooms--one characterized as a…

Geometry and spatial reasoning form the foundations of learning in mathematics. However, geometry is a subject often ignored by curriculum writers and teachers until high school, leading to students lacking in critical skills in geometric reasoning. As the United States moves into a new curriculum epoch, heralding the commencement of the national…

Learning to plan modeling-based investigations (MBIs) presents significant challenges for pre-service elementary teachers. Although they understand disciplinary core ideas and modeling practices, they address both as competing learning goals and, as novices, they have not experienced how to structure MBIs for their future students. In the context…

This report characterizes forms of dialogic support that a sixth-grade teacher generated during whole-class and small-group conversations to help students develop a practice of statistical modeling. During four weeks of instruction, students constructed and revised models to account for variability and uncertainty across a variety of random…

Typically, vocabulary instruction is associated as part of reading instruction. However, vocabulary instruction is also a necessary component of mathematics instruction. In fact, state and national standards (e.g., Common Core State Standards) require elementary students to communicate about mathematics to provide clear explanations, construct…

The study aimed to (1) investigate the components and indicators of active learning instruction competency among elementary school teachers, (2) examine the current state, desired state, and necessary requirements of active learning instruction competency among elementary school teachers, and (3) develop an educational supervision model based on…

This study investigated the effects of 3D model building activities with block codes on students' spatial thinking and computational thinking skills. The study group consists of 5th grade students in a secondary school in the Central Anatolia region of Turkey. For the study, a pretestposttest control group was utilized within the experimental…

The paper reports how a teacher and her students use drawings as a resource for observations and how such observations are connected to different epistemic practices in science lessons. Interactional data in a 1st grade classroom were analyzed based on Ethnography in Education. Results show that the use of drawings materialized children's…

Students are indeed weak when it comes to understanding fractions and decimals. In line with the national curriculum, whole numbers and fractions are taught first before students start to learn decimals. By the time the students approach decimals, they should have acquired sufficient knowledge of whole numbers but limited knowledge of fractions.…
