Regular disciplinary instruction of introductory physics at high school often misses a holistic perspective of the subject matter, its structure, and hierarchy. We have considered the domain of classical mechanics as taught at school and provided such a perspective in the form of a summative lecture which frames content in the triadic structure…

Conrad Hal Waddington (1905--1975) was an English biologist who was especially interested in the big (metaphysical) questions of life. His thinking has become part of the foundation of modern systems biology. This article applies his thinking to middle-years school biology curricula (for ages 11-16), to see if their approach to epistemic questions…

This study aims to determine the knowledge levels in the Nature and History of Science course of the prospective teachers studying in the science education program and their views following the course. Six interview questions were asked to the pre-service teachers in the science education program about the Nature and History of Science course.…

The development of informed views of nature of science is considered to be a crucial aim for science education. This study assesses Portuguese prospective science teachers' views of the nature of science before and after an intervention programme that took place in the first year of their master. Nine prospective science teachers that will teach…

The present study examines the integration level of the Nature of Scientific Knowledge in secondary school science classes in Greece. The research was designed and organized on the basis of the Cultural-Historical Activity Theory. The activity system of the researchers, who use the proper tools each time, are in network relations with the activity…

We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To support these instructional proposals, we identify four rationales for students to understand acid-base processes: daily life, socio-scientific, curriculum, and history of science. The extensive…

This study aims at investigating students' awareness of green chemistry principles (GCPs) which are infused in two context-based projects that are related to socio-scientific issues, namely climate change and materials' recycling. At first, content analysis of the projects' activities showed the infusion of four GCPs. Subsequently, the students'…

The results of studies of the nature of science (NOS) as a factor that enhances students' understanding of evolution have been inconclusive. Therefore, the main purpose of this study was to test the role of NOS instruction in enhancing students' learning about evolution. We used a quasi-experimental design with pre- and post-tests to investigate…

Research on learning about science has revealed that students often hold robust misconceptions about a number of scientific ideas. Digital simulation and dynamic visualization tools have helped to ameliorate these learning challenges by providing scaffolding to understand various aspects of the phenomenon. In this study we hypothesize that…

Playground Physics is a technology-based application and accompanying curriculum designed by New York Hall of Science (NYSCI) to support middle school students' science engagement and learning of force, energy, and motion. The program includes professional development, the Playground Physics app, and a curriculum aligned with New York State…

In an exploratory study, 36 South African physical science teachers' understanding of basic concepts concerning electric and magnetic fields was studied from a perspective of possible concept confusion. Concept confusion is said to occur when features of one concept are incorrectly attributed to a different concept, in the case of this study to…

This study investigated high school students' understanding of fundamental chemistry concepts--states of matter, melting, evaporation, condensation, boiling, and vapor pressure, in relation to their understanding of the particulate nature of matter. A sample of six students (four females and two males) enrolled in a second year chemistry course at…

Research on students' views on nature of science (VNOS) in Asian countries such as China is notably lacking. This study aimed to develop and validate an instrument to measure South China high school students' VNOS. Based on the previously acquired qualitative data, the instrument included seven VNOS dimensions which reflect the crucial aspects of…

The aim of this study was to assess how the different aspects of nature of science (NOS) were represented in Finnish and Swedish upper secondary school chemistry textbooks. The dimensions of NOS were analyzed from five popular chemistry textbook series. The study provides a quantitative method for analysis of representations of NOS in chemistry…

Results from a series of surveys describe dimensions of middle and high school science teachers' preparation for and practices around climate science instruction in the classroom. Descriptions are drawn from 877 respondents to four surveys of US middle and high school science teachers from 2009-2011. Most respondents had engaged in self-directed…
