In order to support physics students in their future careers, there is a need to understand the relationship between undergraduate education and professional practice in physics-related fields. This study investigated high-level goal driven mathematical problem-solving activities that are found within two disciplinary cultures: physical science…

Inorganic phosphors are the main component of light emitting diodes which have caused the revolution in lighting industry as an energy-efficient and long-lasting replacement of traditional incandescent light bulbs and fluorescent tubes. They are also used in various consumer products and displays and can potentially find applications in…

The research presented in this dissertation looks at how students in general chemistry reason about atomic emission spectroscopy. Situated within the context of a transformed general chemistry curriculum called "Chemistry, Life, the Universe, and Everything" (CLUE), the goal of this study was to (1) characterize the various ways in which…

This study was conducted to examine the achievements of students in the concepts of light and shadow measured in different assessment formats according to the learning style and gender. In this study, correlational survey model was used. The sample consisted of 10th grade (16 years) high school students (n=815) from different types of six high…

The aim of this study was to determine the ability of physics teacher candidates' to read a concept map previously prepared by the researchers about a light topic and then convert the concept map into the appropriate text. The study was carried out in the form of case study method in a Turkish University in the Black Sea Region with 32 physics…

In the early nineteenth century, the ideas of reform pedagogues gave rise to a didactic turn towards the visual that criticised an exclusive textual mediation of knowledge through books and lectures. To raise educational effectualness, teachers came under increasing pressure to incorporate high-profile media technologies into their lessons. Yet,…

In this study, it was aimed to examine the science preservice teachers' conceptual structures about the metabolic events taking place and the forms of energy in a cell. In the study, the descriptive model was used. In the study carried out during the spring semester of the 2017-2018 academic year participated a total of 123 third and fourth year…

Excel spreadsheets are used as an excellent tool in physics laboratory experiments related to wave optics. This paper presents a simple way to simulate diffraction of waves through a slit using Excel spreadsheets without any tedious programming. These simulations are used to visualize the effect of variation of different parameters such as number…

In this article, we examine how a sequence of modeling activities supported the development of students' interpretations and reasoning about phenomena with negative average rates of change in different physical phenomena. Research has shown that creating and interpreting models of changing physical phenomena is difficult, even for university level…

The purposes of this research were 1) to develop student's scientific reasoning ability on the concept of light and image at a criterion of 70 using inquiry-based learning 5E with prediction observation and explanation strategy and 2) to compare students' scientific learning achievement on the concept of light and image after using inquiry-based…

We experience (perceive, act upon and react to, and conceptualize) dynamical processes in nature as agentive. Expressed differently, we experience events as resulting from activities and interactions of "Forces of Nature" (such as wind, light, heat, fluids, electricity, substances, and motion) that are conceived of as powerful agents…

Originally an empirical law, nowadays Malus' law is seen as a key experiment to demonstrate the transverse nature of electromagnetic waves, as well as the intrinsic connection between optics and electromagnetism. In this work, a simple and inexpensive setup is proposed to quantitatively verify the nature of polarized light. A flat computer screen…

This paper deals with what it means to sense and touch a real image formed by a spherical mirror using a proximity sensor commonly utilized in smart phones.

A disco ball is a spherical object covered with small plane mirrors. When light reflects on these mirrors, it is scattered in many directions, producing a novel effect. The mirror globe is usually set to rotate, creating a profusion of moving spots (Fig. 1). In this article, we present a geometrical description of the movement of these spots and…

Background: We examine the development of youth sociopolitical consciousness and agency in an eighth-grade science classroom as students of color engage in critical speculative design activities, exploring the multi-scalar, racial realities and possibilities of the science and engineering of pervasive digital technologies--specifically involving…
