Recently, the importance of statistical literacy has been stressed, and three central concepts in statistical literacy are the measures of central tendency: mean, median, and mode. This study explores aspects of statistical literacy expressed by 12-13-year-old students, focusing on mean, median, and mode. Their responses were analysed using a…

When learning about fractions, teaching usually follows certain topics -- e.g. part of the whole, fraction equivalence, and size comparison. Not yet answered is whether students' conceptual and procedural knowledge of fractions is coherent between those topics. To answer this question, we performed a latent profile analysis of data from N = 1005…

Adopting a pretest-posttest experimental design with repeated measures, this study examined the effects of three types of game-based learning supports in the form of modeling on knowledge development that contributed to successful math problem solving and students' perceived game flow. Forty-one sixth-grade students participated in the study and…

Mathematical creativity is considered beneficial for learning mathematics. However, research studies that provide empirical evidence of students' mathematical creativity in regular mathematics classrooms are relatively scarce. This study explores the idea of mini-creativity (mini-c), which is defined as the creative processes involved in the…

Employing Bernstein's (1990, 2000) concepts of recontextualisation and pedagogic discourse, this case study aims to identify types of discourse and forms of knowledge in primary history lessons, and to explain the observations through teachers' thinking. Two Finnish primary teachers were observed for nine or ten consecutive history lessons and…

This study is an exploration of how U.S. middle school students interacted with different topics in world history, and how their specific understandings of topics were connected to both sociocultural and instructional contexts. I observed two world history classrooms in a Midwestern Catholic school for 10 months and conducted task-based group…

This research with middle school students from Kentucky (KY) and Nevada (NV) provides a snapshot of students' spatial-scientific understandings as we explored how well students understand lunar-related content, both spatially and scientifically, after receiving instruction with similar curricular Earth-Space content. Utilizing a lens of spatial…

Energy is a central concept across the sciences and an important goal of science education is to support all students so that they develop a full understanding of the energy concept. However, given the abstract and complex nature of the energy concept, only a few students develop an understanding so that they can use energy ideas to make sense of…

UNESCO has identified education for sustainable development (ESD) as a key factor in the achievement of sustainable development goals (SDGs). Education is important in developing awareness of how to preserve natural ecosystems and promote the uptake of renewable energy sources. Ecology education in primary school aims to give students a scientific…

This is a qualitative case study framed by a sociosemiotic theoretical framework to explore science and language instruction with three Emergent Bilinguals (EBs) in sixth grade. The study details the modeling and explanatory processes used by EBs to mediate science learning through evidence-based argumentation. A thematic analysis of students'…

Physical and virtual labs have unique capabilities that can influence how students learn from them. The purpose of this study was to examine the effect of physical and virtual manipulatives on students' learning of heat and temperature and to examine the influence of various combinations of physical and virtual manipulatives. A total of 205…

This study introduces inferentialism and, particularly, the "Game of Giving and Asking for Reasons" (GoGAR), as a new theoretical perspective for investigating qualities of procedural and conceptual knowledge in mathematics. The study develops a framework in which procedural knowledge and conceptual knowledge are connected to limited and…

Does the timing of children's formal understanding of mathematical equivalence matter for algebra readiness? A change-resistance account (McNeil & Alibali, 2005) predicts that it is beneficial for children to construct a formal understanding of mathematical equivalence in the early grades before overly narrow operational patterns become…

The aim of this research was to explore 11 to 12-year-old children's understanding of the mass of objects made from different materials, and the measurement of this attribute. In depth task-based interviews were conducted with six children attending six different schools; five were in Year 6 and one in Year 7. The children were found to hold…

This study investigated how a computer science (CS) problem-based curriculum impacted elementary students' CS learning and attitudes. Four sixth-grade teachers and 200 of their students participated in the study. Researchers developed a CS curriculum in collaboration with the teachers, which consisted of two main units: (1) an introduction to…
