Comenius (1592-1670) has been widely studied in educational research, although limited work has addressed his thinking about science education comprehensively. His Pansophist philosophy led him to believe that science was a necessary subject for all ("Omnes"). Comenius emphasised useful scientific knowledge and core principles…

To examine differences between sequences of secondary science courses on achievement on science high stakes exams, a purposive quantitative research design was utilized in this study. A short survey was sent out to public high schools in the state of Missouri that asked to identify their main science course sequence. In addition, participants were…

For a sample of 367 middle-school students in the USA, learning environment criteria were used to evaluate two alternative science curriculum sequences (generalised/integrated and topic-based) and to investigate the differential effectiveness of the alternative sequences for two different ethnic groups (Caucasian and Hispanic). The six scales used…

This paper examines how students make progress toward three-dimensional (3D) understanding of the patterns of evolution. Specifically, it proposes a learning progression that explains how scientific practices, crosscutting concepts, and disciplinary core ideas come together in naming and grouping, length of change over time, and the role of common…

This study explored the organization of contents in the junior secondary science curriculum of Bangladesh. The research questions of this study focus on how science content is sequenced and integrated in the intended curriculum. Document analysis within a qualitative approach has been followed to conduct this study. Both junior secondary science…

This article examines the process of shifting to a "Physics First" sequence in science course offerings in three school districts in the United States. This curricular sequence reverses the more common U.S. high school sequence of biology/chemistry/physics, and has gained substantial support in the physics education community over the…

We evaluated the effectiveness of two alternative middle-school science curriculum sequences, namely, a general science model and a topic-specific model (i.e., physics, chemistry, etc.). We also investigated the differential effectiveness of the alternative sequences for two ethnic groups. The sample consisted of 367 grade 8 science students from…

Since the inception of the National Center for Engineering and Technology Education in 2004, educators and researchers have struggled to identify the necessary components of a "good" engineering design challenge for high school students. In reading and analyzing the position papers on engineering design many themes emerged that may begin to form a…

Studies of high-school science course sequences have been limited primarily to a small number of site-specific investigations comparing traditional science sequences (e.g., Biology-Chemistry-Physics: BCP) to various Physics First-influenced sequences (Physics-Chemistry-Biology: PCB). The present study summarizes a five-year program evaluation…

This article suggests that a genuine reform endeavor towards the "Science for All" paradigm should adopt a holistic approach. There are several countries around the world that adopted the "Science for All" paradigm at the beginning of the 21st century. However, while looking closely at the amount of change that took place in…
