tandfonline.com – Jumping pepper and electrons in the shoe: using physical artefacts in a multilingual science class

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT This article concerns how teachers can use physical artefacts as mediating means to support emergent bilingual students’ learning in science class. The data consist of non-participant observations in a Swedish 3rd grade (9–10 years old) class working with electricity. All students were bilingual, but in different minority languages and the teacher was monolingual in Swedish. The study focused on four students, all of whom had Turkish as their minority language. The findings show that the teacher used physical artefacts in two different ways. First, the physical artefacts implied that the students experienced the science content by actually seeing it. The students talked about their observations in everyday language, which the teacher then drew on to introduce how the… Continue Reading →

tandfonline.com – Enhancing young children’s understanding of a combinatorial task by using a duo of digital and physical artefacts

Posted on by Troels Gannerup Christensen - Læst 5 gange

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT In mathematics education, digital tools have been used to enhance young children’s understanding of specific subject matter. In such implementations, the digital tool can replace, amplify or transform ‘ordinary’ mathematics teaching. In an initial study, systematization and duplication were identified as critical when young children were to solve a combinatorial task. Therefore, a digital version of the task was developed and combined with a non-digital version, to introduce the use of dual artefacts. The digital version of the task enabled the children to visually explore systematization as well as the principle of completion. After using this digital version of the task, the children’s written records became more systematic and included fewer duplications. We conclude that the digital version… Continue Reading →
