For an educational reform to succeed, teachers need to adjust their perceptions to the reform’s new curricula and strategies
and cope with new content, as well as new teaching and assessment strategies. Developing students’ scientific literacy through
context-based chemistry and higher order thinking skills was the framework for establishing a new chemistry curriculum for
Israeli high school students. As part of this endeavor, we developed the Taste of Chemistry module, which focuses on context-based chemistry, chemical understanding, and higher order thinking skills. Our research
objectives were (a) to identify the challenges and difficulties chemistry teachers faced, as well as the advantages they found,
while teaching and assessing the Taste of Chemistry module; and (b) to investigate how they coped with teaching and assessing thinking skills that include analyzing data from
graphs and tables, transferring between multiple representations and, transferring between chemistry understanding levels.
Research participants included eight teachers who taught the module. Research tools included interviews, classroom observations,
teachers-designed students’ assignments, and developers-designed students’ assignments. We documented different challenges
teachers had faced while teaching the module and found that the teachers developed different ways of coping with these challenges.
Developing teachers’ assessment knowledge (AK) was found to be the highest stage in teachers’ professional growth, building
on teachers’ content knowledge (CK), pedagogy knowledge (PK), and pedagogical-content knowledge (PCK). We propose the use
of assignments designed by teachers as an instrument for determining their professional growth. 相似文献

Six natural history institutions contributed video and other images to produce a single multimedia exhibit about famous paleontology sites throughout the United States. In Mesozoic Monsters, Mammals and Magnolias, users can view videos of the original excavation of each of the sites and also play computer games relating to each location. This project provides a model for how collaboration among museums can reduce the cost of multimedia exhibits while improving quality and making them available to wider audiences. 相似文献
