Schools today face the challenge of preparing students to live, work, and prosper in a rapidly changing world. As a response to this global challenge, Norway has adopted a national curriculum focusing on the development of 21st-century skills. In this study, we investigate if and how the tasks in science and language arts textbooks in…

How teachers make sense of new academic standards significantly shapes the implementation of those standards. Professional development organized around the analysis of mathematical tasks has potential to prepare teachers for standards implementation by helping them develop common understandings of standards and how to help students meet ambitious…

How can geometry teachers design great tasks that allow students to make connections among interrelated concepts and expand their geometric reasoning skills? Many curricular materials provide problems for students to apply a single geometric concept. However, these problems do not always promote reasoning opportunities for students, because…

In this paper we focus on variation of the design and the implementation of a specific task during three mathematics lessons in the 8th grade in a learning study (Marton & Tsui, 2004; Runesson, 2008). The theme of the lesson was division, with a denominator between 0 and 1. The teachers wanted their students to understand that when dividing…

While much has been written about task-based language teaching (TBLT), research examining teachers' understandings of what TBLT means remains limited. This article explores the understandings of TBLT of three Chinese secondary school teachers of English and the implementation of TBLT in their lessons. Narrative accounts were constructed for each…

The major literature review by Black and Wiliam (1998a) provided strong research evidence indicating that assessment for learning can produce significant gains in students' learning. The present study applied the main aspects of assessment for learning, as highlighted in the Black and Wiliam review, in a specific area of science education, that of…
