Understanding experimental design (e.g. control of variable strategy or CVS) is foundational for scientific reasoning. Previous research has demonstrated that demonstrations with cognitive conflict (e.g. asking students to evaluate and explain different experimental designs) are effective in promoting children's scientific reasoning, however, the…

We report on a scaled-up mathematics intervention in preschool classes (children age six) in Sweden. In the intervention, teachers at seven schools in four municipalities implemented the Thinking, Reasoning and Counting in Preschool Class (TRC) teacher guide in their teaching of 254 students. Results are compared to a previous randomized…

Children's preschool years are crucial for the development of computational thinking (CT) skills. However, debate continues regarding whether CT should be developed through plugged-in or unplugged activities. This study investigated the similarities and differences between plugged-in and unplugged activities with similar learning content and…

The interest in computational thinking development at pre-university education stage is increasing. In this study, a meta-analysis was conducted to address two main objectives: (a) to analyze the effectiveness of empirical interventions in K-12 education for the development of Computational Thinking (CT); and (b) to identify and evaluate the…

Picture book reading is essential in the early stages of learning and development. The current study aimed to incorporate picture books to improve first graders' scientific thinking, including scientific reasoning and creativity. The study adopted a quasi-experimental research design. There were 24 students in the experimental group and 23 in the…

This paper considers one of the relevant problems of modern pedagogy - the use of logical approaches in teaching to the development of thought and language of primary schoolchildren. The purpose of the study is to determine the main criteria for the developmental education of thought and language to primary school children and to assess the level…

The purpose of this study was to characterize variations in how teachers enacted an approach to ambitious mathematics teaching: "rough draft math." We also examined teachers' motivations for their enactments. Thirty-two teachers from five states in the U.S.A. were recruited to participate in interviews based on recommendations from…

This paper describes the implementation and student learning outcomes of a nationwide professional development program for lower secondary and upper secondary school teachers to integrate computational thinking into the K-12 curriculum. Computational thinking comprises important concepts and skills that all students should develop to take an…

The study explored the effects of an interdisciplinary learning approach on developing students' English learning (EL) and computational thinking (CT) through two different game-based learning approaches. A quasi-experiment was conducted to evaluate the effectiveness of this approach in terms of enhancing students' CT knowledge and their EL…

Design-based learning has been recognized by educational scholars as the key approach to science, technology, engineering, and mathematics (STEM) education at K-12 levels. However, it is unclear whether, and which dimensions of, design thinking mindsets support the conceptual learning of science. This quasi-experimental study aims to explore 37…

This study examines the collective mathematical reasoning when students and teachers in grades 3, 4, and 5 explore fractions derived from length comparisons, in a task inspired by the Elkonin and Davydov curriculum. The analysis showed that the mathematical reasoning was mainly anchored in mathematical properties related to fractional or algebraic…

The inclusion of Computational Thinking (CT) in the classroom along with the promotion of positive attitudes in early ages towards technology have great relevance in the current educational paradigm. This study analyses whether CT instruction may improve pupils' attitudes towards technology, and also considers whether instructional approaches and…

Powell, Berry, et al. (in press) conducted a randomized control trial assessing the effects of two variants of word-problem intervention with third graders (n = 304) experiencing mathematics difficulty. Students were assigned to a business-as-usual condition (BaU) or one of two variants of word-problem intervention. One variant included a…

While programming was introduced to mathematics classrooms in the 1980s, emerging robotic technologies have encouraged more widespread integration of these technologies to support the development of K-12 students' mathematical reasoning. The recent emphasis of programming and computational thinking in K-12 education has highlighted the need to…

Block building activities help develop students' spatial reasoning, but few studies focus on the development of block building skills beyond preschool. We worked with four kindergarten, four first grade, and four second grade students to learn more about their Lego block building. We compared students' accuracy, building strategies, and spatial…
