In recent years, many studies have researched the impact of teachers' professional knowledge on teaching quality. Those findings are still ambiguous providing unclear evidence for supporting teacher education programs that aim at developing professional knowledge. In this study, we followed a new approach and used a "performance test" to…

We compute nodal centrality measures on the collaboration networks of students enrolled in three upper-division physics courses, usually taken sequentially, at the Colorado School of Mines. These are complex networks in which links between students indicate assistance with homework. The courses included in the study are intermediate classical…

'Program development' is a systematic process which includes steps such as determining general and specific goals of teaching, choosing appropriate program materials, determining teaching methods, evaluation and assessment tools, designing formal outlines for every lesson, testing and finalizing the program, continual monitoring, evaluating…

One of the central goals of modern science and chemistry education is to develop students' abilities to understand complex phenomena, and productively engage in explanation, justification, and argumentation. To accomplish this goal, we should better characterise the types of reasoning that we expect students to master in the different scientific…

Quantum physics describes light as having both particle and wave properties; however, there is no consensus about how to interpret this duality on an ontological level. This article explores how pre-university physics students, while working with learning material focusing on historical-philosophical aspects of quantum physics, interpreted the…

Science students should use mathematical and computational thinking to explain phenomena, but few examples of teachers engaging students in this important scientific practice have been found. This article describes a strategy for enhancing a lesson in which students use a mechanistic model to explain friction by adding mathematical and…

Authorial Stance is an important aspect in academic texts in academic texts such as research articles (RAs); that is to show the attitude of authors toward the information cited in a reference in order to establish an argument. The objective of this research was to investigate the authorial stances in English RA introductions written by Indonesia…

The large flood of data flowing from observatories presents significant challenges to astronomy and cosmology--challenges that will only be magnified by projects currently under development. Growth in both volume and velocity of astrophysics data is accelerating: whereas the Sloan Digital Sky Survey (SDSS) has produced 60 terabytes of data in the…

The resources presented in this chapter are based on video presenting a variety of practices. This design is based on classroom videos, collected as data in research studies on science classroom practices in relation to students' learning. The first part of the chapter will present the analysis of a 10th grade physics classroom during a teaching…

Ivã Gurgel, Mauricio Pietrocola, and Graciella Watanabe expand upon the existing literature, which links identity and science engagement. Specifically, the authors focus on ways in which the cultural identities of students relate to their engagement in physics. In doing so, Gurgel, Pietrocola, and Watanabe further build upon the idea that one's…

The present essay examines the emerging issue of domain-general versus domain-specific nature of science (NOS) understandings from a perspective that illuminates the value of domain-specific philosophies of science for the growth and development of the NOS educational field. Under the assumption that individual sciences do have their own…

Achievement in the professions is situated relationally. Work comes to constitute contribution only by the judgments of colleagues. This is paradigmatically the case in science and scholarship, where colleagues not only sanction others but also create their legacy. Normatively, it would stand to reason that colleagues would be held in high regard;…

As we near the close of another academic year, we highlight departments in the United States that consistently award more physics bachelor's degrees than other similar departments. We categorize departments by the highest physics degree they award. Typically, departments that award a doctorate have more faculty members and more students; thus, one…

This paper presents a method to measure the movement of an object from specific locations on a straight line using an iPhone's magnetometer. In this method, called "magnetogate," an iPhone is placed on a moving object (in this case a toy car) and small neodymium magnets are arranged at equal intervals on one side of a straight line. The…

Force probes are versatile tools in the physics lab, but their internal workings can introduce artifacts when measuring rapidly changing forces. The Dual-Range Force Sensor by Vernier uses strain gage technology to measure force, based on the bending of a beam. Strain gages along the length of the beam change resistance as the beam bends. The…
