Curriculum

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.

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.

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.
