Science appears to be coming under increasing pressure in parts of society and the media, with an increase in 'fake news' and less regard for 'experts'. If this is to be combatted, it is important that students develop a good understanding of both the big conceptual ideas of science and the nature of science itself. This understanding will mean…

The authors conducted a qualitative content analysis of the 400 National Science Teachers Association Outstanding Science Trade Books for Students K-12 from 2010-2017 selected for their instructional usefulness in science classrooms. The authors examined these expert-recommended science trade books to better understand their design and to identify…

Research on nature of science (NOS) has confirmed that students' understanding of NOS is best achieved by explicitly considering NOS a cognitive learning expectation and providing opportunities to reflect on it. However, little has been discussed on how to design and use tasks enhancing students' NOS understanding. In an attempt to fill this gap,…

The word "wave" is part of the daily language of every student. However, the physical understanding of the concept demands a high level of abstract thought. In physics, waves are oscillating variations of a physical quantity that involve the transfer of energy from one point to another, without displacement of matter. A wave can be…

On the first day of class I ask my students, "What makes a true statement true?" Then I tell them that they might be surprised to learn that there are only two types of true statements in physics, and I encourage them to try to discover the two categories.

This investigation explored a learning community approach to professional development (PD) specifically catered to science teacher educators. It was designed to bolster faculty collaboration, help participants learn about new research relevant to teacher development, and share effective teaching strategies. Forty-four science teacher educators…

Analysing graphs, formulating covariational relationships, and hypothesizing systems' behaviour have emerged as frequent objectives of contemporary research in physics education. As such, these studies aim to help students achieve these objectives. While a consensus has been reached on the cognitive benefits of emphasizing the structural domain of…

Newton's third law is one of the most important concepts learned early in introductory mechanics courses; however, ample studies have documented a wide range of students' misconceptions and fragmented understandings of this concept that are difficult to change through traditional instruction. This research develops a conceptual framework model to…

This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

Describing the motion in a vertical roller coaster loop requires a good understanding of Newton's laws, vectors and energy transformation. This paper describes how first-year students try to make sense of force and acceleration in this example of non-uniform circular motion, which was part of a written exam. In addition to an analysis of the exam…

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…

A "Framework for K-12 Science Education and the Next Generation Science Standards" ("NGSS") are intended for all students, hence "all standards, all students" (NGSS Lead States 2013). To make this vision a reality, the "NGSS" highlight three key instructional shifts: (1) explain phenomena or design solutions…

Recent research on science teaching and learning defines science as both a body of knowledge and a process (NRC 2007); it is the integration of science content, practices, and core ideas (NRC 2012). It would follow that science learning should parallel what science is and how it is done; students should not be just consumers of scientific…

In this study, we probed high school students' understanding of Einstein's theory of gravity by implementing an approach which mainly consists of two steps: firstly, exposing students to TEs describing the Equivalence Principle; secondly, applying the analogy of parallel lines on a curved surface with the path of two falling balls in a real…

This work focuses on the experimental demonstration of the hydrostatic paradox using simple tools in the form of plastic bottles and plastic syringes with a thread. For the evaluation of the results obtained the data logger Lab Quest Vernier was used. The construction of the device is presented in the first part of this paper. The second part…
