We use a validated conceptual multiple-choice survey instrument focusing on thermodynamic processes and the first and second laws of thermodynamics at the level of introductory physics to investigate the problem-property dependence of introductory and advanced student responses to introductory thermodynamics problems after traditional…

This study investigated evidence of how students' mental models of fundamental kinematic relations evolved (i.e., developed cognitively over time) as observed during an introductory course in calculus-based classical mechanics. The core of the curriculum is based on a claim known as Galileo's principle of relativity. The course material comprised…

Previous research has shown that in prehigher education stages, inquiry-based teaching is not sufficient for forming a mature understanding of the nature of science (NOS). However, there is relatively little research conducted on colleges. Inquiry-based teaching should not overlook cognitive frameworks, as students' limited scientific reasoning…

Although laboratory work is considered a significant factor in helping students develop their science process skills and cultivate alternative knowledge construction, there are still gaps in the selection, integration, and implementation of the basic elements in physics laboratories. In this study, three modified guided discovery and conventional…

The study consisted of three articles. Article one aimed to determine if there were any significant difference in science graduate students' (SGSs') conceptions of the "consensus tenets" of the nature of science (NOS) with respect to demographic factors -- the SGSs' academic and research characteristics. The participants were SGSs from…

The purpose of this study was to explore grade eight students' views in terms of different scientific reasoning progress levels. To explore students' views, phenomenographic study was used. The qualitative analysis of students' interviews elicited three major themes of students' views about scientific reasoning progress levels: naïve, mixed, and…

In this study, we examined the teaching emphasis of the history of science (HOS) in science lesson plans. The examination was based on a five-dimensional framework, which comprises conceptual, procedural, epistemological, affectional, and social dimensions. Content analysis was employed as the research methodology, targeting 71 copies of science…

Science students should undertake engineering design projects and carry out scientific investigations, as recommended by the "Next Generation Science Standards" (NGSS Lead States 2013). However, studies show that students misconstrue the goals of science and engineering and are uncertain about their respective practices (Gilbert and Wade…

Science teaching and learning require knowledge about how learning takes place (cognition) and how learners interact with their surroundings (affective and sociocultural factors). The study reported on focussed on learning for understanding of Newton's second law of motion from a cognitive perspective that takes social factors into account. A…

This article presents an instructional strategy called Premise-Reasoning- Outcome (PRO) designed to support students in the construction of scientific explanations. Informed by the philosophy of science and linguistic studies of science, the PRO strategy involves identifying three components of a scientific explanation: (i) premise--an accepted…

Amusement park physics is a popular way to reinforce physics concepts and to motivate physics learners. This article describes a novel physics competition where students use simple tools to take amusement park ride measurements and use the data to answer challenging exam questions. Research into the impact of participating in the competition…

Adding Mentos to an open bottle of Diet Coke can produce a fountain of liquid and froth extending several metres high. This activity can engage a wide audience of learners in a relevant and meaningful way, provide a model for creative science teaching, and help to develop learners' attitudes towards school science as a subject. In this paper, the…

This study considers whether Model Based Inquiry (MBI) is a suitable mechanism for facilitating science as inquiry to allow students to develop deep understandings of difficult concepts, while also gaining better understandings of science process and the nature of science. This manuscript also considers time devoted to MBI in comparison to more…

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 paper describes a method and setup to quickly and easily measure a model rocket engine's thrust curve using a computer data logger and force probe. Horst describes using Vernier's LabPro and force probe to measure the rocket engine's thrust curve; however, the method of attaching the rocket to the force probe is not discussed. We show how a…
