Developing scientific literacy about water systems is critical for K-12 students. However, even with opportunities to build knowledge about the hydrosphere in elementary classrooms, early learners may struggle to understand the water cycle (Forbes et al., [Forbes, C. T., 2015]; Gunckel et al., [Gunckel, K. L., 2012]; Zangori et al., [Forbes, C.…

High level, abstract engineering thinking and design is a subject that is hardly addressed in current curricula for secondary education. This is contradictory to the increasing need for more in depth STEM education in secondary schools dictated by the evolution of our society towards an ever more STEM based information society. In this paper an…

Active-learning strategies such as undergraduate research courses and course-based undergraduate research experiences (CUREs), which engage students in the practical experiments, have been reported as efficient ways for effective teaching and training of graduating students. Recently, many practical examples have been published in various fields…

In this exploratory study, we looked at the effect adding a choreographed song to camp had on middle-school aged campers' retention of two concepts: order of the planets with increasing distance from the Sun, and phases of the Moon listed in the correct order. We conducted pre- and post-assessments on these questions for multiple years of the…

This study provides an analysis of selected aspects of the intended curriculum related to redox reactions as represented in secondary chemistry textbooks from the People's Republic of China, with a special view also on Hong Kong, Shanghai, Taiwan, and the Chinese minority in Malaysia. This study reveals how chemistry textbooks deal with visual…

Mechanistic reasoning, or reasoning systematically through underlying factors and relationships that give rise to phenomena, is a powerful thinking strategy that allows one to explain and make predictions about phenomena. This article synthesizes and builds on existing frameworks to identify essential characteristics of students' mechanistic…

Purpose: This paper aims to investigate the knowledge, attitude and behaviour of foundation chemistry learners concerning the sustainable development concept. Design/methodology/approach: Qualitative and quantitative studies were conducted. Atlas.ti software was used to analyse the chemistry curriculum based on selected themes and sub-themes. A…

While curriculum designed as project-based learning is not suitable for use with every science standard, this methodology can be used when teaching concepts that naturally contain some flexibility. With small adaptations, teachers can implement these practices into the classroom regardless of the grade level. This article provides a detailed…

Problem-based learning (PBL) involves students solving a problem with multiple solutions over time, like scientists in real-world contexts. This fourth-grade PBL unit had students become part of an endeavor to help their state of Virginia become energy independent. It conceptualized energy independence as becoming self-sufficient for energy…

A recent framework on nature of science (NOS) is the Family Resemblance Approach (FRA). FRA presents NOS as a cognitive-epistemic and social-institutional system with a set of categories: aims and values, scientific methods, scientific practices, scientific knowledge and social-institutional aspects of science. Although FRA has been problematised…

In this paper we present a pedagogical strategy to introduce the Heisenberg uncertainty principle to high school students. The basis on which this proposal relies is the Fourier transform, connecting the quantum function in the x domain, ?(x), with the function in the wave number domain, A(k). This mathematical relationship directly leads to the…

Students with visual impairments have the same span of cognitive abilities as their peers, but science instruction typically relies very heavily on vision. The preponderance of visually oriented and visually complex science concepts poses significant challenges to learning among students with visual impairment. This study is engaging, hands-on…

This dissertation includes two independent research projects, one in astronomy education research and the other in planetary science/astrophysics research. In the first research effort, we investigate college students' conceptual and reasoning difficulties on the topic of planet formation pre-instruction. Through an analysis of over 1,000…

The purpose of this research was to know what the effect of the use of multiple representations (MR) was in the development of the students' cognitive structures. This research was conducted in three Grade 12 classes, in a total of 68 students. A Word Association Test (WAT) was used as data collection instrument. The results from WAT show that…

Throughout development, children undergo moments of abrupt conceptual transitions, often replacing intuitive knowledge with grounded scientific theories. This typically also creates a situation of social conflict, as different children may hold at the same time substantially different theories and explanations about the same phenomenon. The main…
