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 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…

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,…

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…

Web-based applications in education seem to be increasing day by day. As in all fields of education, web-based teaching practices are being developed to make the subjects learn better in science. The web-based instruction on science education for 6th-grade students, light and sound unit, a reflection of light was designed according to Dick and…

Student's mental representations of physical concepts are often different from those of scientists. The research aimed to identify and compare mental representations of light propagation time by school children aged 10 (132 subjects), and 14 (109 subjects) years old. This research was conducted through individual interviews in which the students…

This article introduces a science game which can be used for innovative teaching and as an assessment tool. The Shadow Races Game is designed for first and second grade students to learn the phenomenon of shadow through inquiry-based activities and questions that require the children to apply inferences from those activities. In this amusing board…
