Inquiry instruction often neglects graphing. It gives students few opportunities to develop the knowledge and skills necessary to take advantage of graphs, and which are called for by current science education standards. Yet, it is not well known how to support graphing skills, particularly within middle school science inquiry contexts. Using qualitative graphs is a promising, but underexplored approach.

We report on the use of bilingual constructed response science assessments in the context of a research and development partnership with secondary school science teachers. Given the power that assessments have in today’s education systems, our project provided a series of workshops for teachers where they explored students’ emergent reform-oriented science meaning-making in our project-designed assessments.

The success of the Next Generation Science Standards (NGSS) and similar reforms is contingent upon the quality of teaching, yet the shifts in teaching practice required are substantial. In this study, we propose and validate a model of adaptive expertise needed for teachers to successfully deliver NGSS-informed computer-supported complex systems curricula in high school science classrooms.

Graphs illustrating complex scientific relationships require students to integrate multiple concepts and visual features into a coherent understanding. We investigate ways to support students in integrating their understanding of density concepts through a graph that is linked to a simulation depicting the relationship between mass, volume, and density. We randomly assigned 325 8^th-grade students to 1 of 2 graphing activities.

Incorporating scientific uncertainty as part of science teaching means acknowledging that there may be incomplete or potentially limited scientific information when scientists draw conclusions. In the geosciences, scientists routinely make inferences about the Earth based on observations of the present, and test those observations against hypotheses about Earth’s history and processes that are not readily observable.

In this article, we turn our attention to context-based approaches to science instruction. We studied the effects of changes to a set of secondary science teacher education programs, all of which were redesigned with attention to the Secondary Science Teaching with English Language and Literacy Acquisition (SSTELLA) instructional framework, a framework for responsive and contextualized instruction in multilingual science classrooms. Contextualizing science activity is one of the key dimensions of the SSTELLA instructional framework.

Recent reform efforts in science education include a focus on science practices. Teachers require support in integrating these practices into instruction. Multimedia educative curriculum materials (MECMs), digital materials explicitly designed to support teacher learning, offer one potential resource for this critical need. Consequently, the authors investigated how teachers used MECMs and whether that use impacted their beliefs about the practice of scientific argumentation. They conducted a randomised experimental study with 90 middle school science teachers in the USA.

Implementation of reform curricula requires teachers to adopt new approaches to teaching. Research has provided promising results about the influence of educative curriculum on teachers’ learning and instruction. However, this approach generally focuses on teachers as isolated learners. Using a design-based research approach, the authors developed a web-based tool, iPlan, which provides access to educative curriculum materials in an online interactive learning platform.
