In recent years, single-subject experimental courses have not been able to meet the demands of the comprehensive development of life sciences. This study is based on two fundamental disciplines, molecular biology and metabolomics, with the analysis and intervention of tumor-related genes as the starting point. A comprehensive experimental course…

[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] Although curriculum design has a long tradition in physics education research (PER), it is often criticized for unclear or inconsistent methodologies. One reason is that the theory-into-practice aspect frequently remains blurred. Only a few curriculum…

This research evaluated the implementation of a climate science curriculum intervention for students in Grades 4 and 5, including those who were typically achieving and those with difficulties in mathematics, reading, or both. Pre- and posttests of measurement and climate change science concepts were administered at the beginning and end of each…

In 2017, a change to the national curriculum of New Zealand required primary teachers to implement a new component into the Technology area of The New Zealand Curriculum. This was to be fully implemented by the start of the 2020 school year. However, unless this was a personal area of ability, no primary teacher in New Zealand has been trained or…

We present main effects of treatment and moderating effects of student background on science and engineering outcomes for grades 3-5 children participating in an engineering intervention. Data is from a large-scale randomized-controlled trial of two matched pairs (intervention and comparison) of engineering units. The intervention curriculum…

Traditional modes of chemistry education in schools focus on imparting chemistry knowledge to students via instruction. Consequently, students often acquire the mistaken understanding that scientific knowledge comprises a fixed body of "proven" facts. They fail to comprehend that the construction of scientific understanding is a human…

This study focuses on how the treatment effects of a teacher professional development initiative in science differed by school capacity. In other words, the authors are primarily concerned with treatment effect heterogeneity. As such, this paper complements ongoing evaluation of the average treatment effects of the initiative over time. The…
