Conventional coordinate systems are often considered representational tools for reasoning about mathematical concepts. However, researchers have shown that students experience persistent difficulties as they engage in graphing activity. Using examples from research and textbooks, we present a framework based on a conceptual analysis of the use of…

In this paper, I will report on the progress made in designing a curriculum for intensive language training, in which one-on-one instruction is combined with online exercises and drills to achieve an optimal blend of expertise and technology enhanced language learning. The Common European Framework of Reference (CEFR) has become a crucial tool for…

In recent years there has been an increased emphasis on algebraic reasoning in primary school classrooms. This includes introducing students to the mathematical practices of making conjectures, justifying and generalising. Drawing on findings from a classroom-based study, this paper explores one teacher's journey in shifting her task design and…

We traced the impact of a sequence of five research-based professional development sessions on a cohort of mathematics teachers' Mathematical Knowledge for Teaching. The sessions focused on task design and implementation as a means of building teachers' pedagogical capacity. Findings revealed that teachers' pedagogical knowledge pertaining to…

This paper provides a starting point for the systematic design of instruction to integrate environmental education content curricula-wide. In order to facilitate the integration of environmental education into technology programs in particular, the paper addresses each of the following associated issues: (1) lack of agreement as to the relative…

This paper presents a model of an interactive mode for instructional research and development that might yield both curriculum products and scientific knowledge concerning learning and instruction. Curriculum development is discussed as an applied science and as an art, using specific research and development efforts conducted at the Learning…

Set in the context of Hong Kong's school curriculum reform initiative, which centers on development and implementation of task-based instruction, a study examined: (1) what teachers of English as a Second Language understand about language learning and what decisions they make when preparing a classroom task; (2) to what extent elementary and…

This report describes the Florida Vocational Division's efforts to increase the quality, validity, transportability, and availability of curricular materials through use of performance objectives; establishment of a curriculum laboratory; adoption of systematic models for instructional design; and establishment of a diffusion/dissemination system.…
