This paper comprises the results of a design study that aims at developing a theoretically and empirically based learning trajectory on statistical inference for 9th-grade students. Based on theories of informal statistical inference, an 8-step learning trajectory was designed. The trajectory consisted of two similar four step sequences: (1)…

The purpose of this study was to analyze the effectiveness of scripted biology curriculum as a means of providing students with the information required to increase content knowledge, while comparing curriculum developed by the teacher that utilizesthe Understanding by Design (UbD) framework (Wiggins & McTighe, 2005). The study used a mixed…

The purpose of this semester-long project was to redesign the ninth grade English language arts curriculum to include a literacy-based multicomponent intervention to meet the needs of developing readers, while simultaneously maintaining a rigorous curriculum challenging proficient readers in a general education classroom. I examined peer-reviewed…

This study bridges teacher leadership research with principles of co-design in an effort to understand teachers' experiences with co-design as a process of teacher leadership and its implications for strengthening teacher leadership development efforts. Using qualitative data from a multi-year co-design research project aimed at developing…

Many adolescents need additional support during the early years of high school to develop their reading skills, but secondary teachers often have few options available that meet the unique literacy needs of this population. Therefore, the purpose of this study was to design and investigate an innovative approach to help adolescent readers with a…

Science capabilities were introduced within the New Zealand context following the revised "New Zealand Curriculum" (NZC). These capabilities are a small set of things that NZC intends students to be able to do in science, which weave the nature of science with content strands. Using pedagogical content knowledge (PCK) to understand…

Artificial intelligence (AI) education is still in the exploratory stage for K-12 schools. There is a serious lack of studies that informed schools teachers about AI curriculum design. Accordingly, this paper presented an AI curriculum and examined whether the curriculum improves students' perceived AI knowledge, attitudes, and motivation towards…

When mathematics teachers plan lessons, they interact with curriculum materials in various ways. In this paper, we draw on Brown's (2009) "Design Capacity for Enactment" framework to explore the practice of "adapting" curriculum materials in the case of a Singapore secondary mathematics teacher. Problems from the textbook used…

This study addresses the inadequacies of the traditional ninth-grade science curriculum at The Charter School of Wilmington (CSW) and proposes a focused initiative to enhance the curriculum's relevance and effectiveness. The current Integrated Science & Research curriculum lacks socioscientific inquiry, neglecting to incorporate social issues…

An adequate understanding and classroom application of the Nature of Science (NOS) has become imperative for science teachers. Current research in senior high school science teachers' understanding of NOS is extensive but junior high school natural sciences teachers' understanding of NOS and planning of lessons requires further exploration. Six…

This study describes the work of one high school team in designing, developing, supporting, and field-testing a new course to support numeracy and general learning skills for a particularly diverse population of students. The rationale, curriculum design, and pilot implementation of the course are situated in existing curriculum structures and…

Purpose: The purpose of the study was to evaluate the implementation and impact of the IDEA Public Schools' Mathematics Curriculum Redesign (MCR) effort, funded by an Innovation and Research (EIR) grant. Methods: The study used a quasi-experimental matching design to examine the effect of MCR on student achievement outcomes. The study compared…

Socioscientific Inquiry (SSI) represents an instructional approach designed to target interest and knowledge in science. In this context, students consider scientific issues that have social implications and comprise a range of trade-offs, concepts, and considerations in order to arrive at informed conclusions (Sadler, 2004, 2011). Given the…

Debates continue about how high-stakes testing regimes influence schools at all levels: their impact on teaching practices, distribution of resources and curriculum provision, and whether they achieve the intended increases in student achievement in targeted areas. In 2008, the Australian government Introduced a national testing scheme, the"…
