Active learning techniques are generally considered to be any classroom activities in which students become an active participant in learning, instead of a passive listener to a lecture. Service learning activities are generally experiential (real life) and reflective problem-based learning activities in which students enrolled in an academic…

We propose an easy experiment that allows students to determine the speed of sound through a simple time-of-flight measurement using two smartphones. The concept of using the sensors in mobile phones for physics experiments has become a well-known option for science teachers. Since these devices are readily available to most students and teachers,…

In this work we construct a timer system consisting of both hardware and software to be used in introductory-level laboratory physics courses. The Parallax P8X32A propeller based-microcontroller hardware consist of a board that registers the times of events triggered when IR photogates are blocked and unblocked. The software allows the user to…

Students often have difficulties comprehending situations in which wave characteristics of light are manifested. After teaching wave optics, we studied the level of understanding of reflective diffraction of light with a group of secondary school students, and the phenomenon of diffraction in general. We analysed the possibility of using…

Since the emergence of augmented reality (AR), it has been a constant subject of educational research, as it can improve conceptual understanding and generally promote learning. In addition, a motivational effect and improved interaction and collaboration through AR were observed. Recently, AR technologies have taken a major leap forward in…

In this paper we present a novel approach to teach kinetic energy as an observable and measurable concept. The fundamental principles have been outlined for gravitational potential energy in an earlier work, that we extend here. By accelerating or decelerating bodies with springs we begin, in a first step, with a direct comparison method for…

The purpose of this exploratory qualitative study was to investigate prospective elementary teachers' conceptual understanding of buoyancy. Specifically, the study aimed to identify the scientifically accepted conceptions, and misconceptions that preservice teachers hold about buoyancy using an instructional intervention. Presently, there is a gap…

Relational interlinked dependencies between concepts constitute the structure of abstract knowledge and are crucial in learning conceptual knowledge and the meaning of concepts. To explore pre-service teachers' declarative knowledge of physics concepts, we have analyzed concept networks, which agglomerate 12 pre-service teacher students'…

The labs presented here build on a simple speed of sound activity and models medical ultrasound imaging by demonstrating how multiple reflections propagate in a closed system. A short sound pulse is emitted into a pipe that is closed at one end and contains one or more partially reflecting surfaces within the pipe. The variety of reflections and…

This paper presents the usage of an Excel spreadsheet for studying charged particle dynamics in the presence of uniform electric and magnetic fields. The equation of motion of the charged particle is developed under different conditions and the data is obtained in an Excel spreadsheet under variation of parameters such as the velocity of charged…

In this paper we present the results derived from a project aimed to study the "learning gains" obtained by undergrad engineering students that used two mobile learning resources (in video format). We conducted our study over a 6-year time interval applying "pre-test" and "post-test" instruments to both experimental…

This dissertation research focuses on investigating the incidence of student self-regulated learning behavior, and examines patterns in student affective states that accompany such self-regulated behavior. This dissertation leverages prediction models of student affective states in the Physics Playground educational game platform to identify…

We present a programmatic study of physicists' and astronomers' attitudes toward education and public outreach (EPO) using 131 survey responses from members of the Dark Energy Survey. We find a disparity between the types of EPO activities researchers deem valuable and those in which they participate. Most respondents are motivated to engage in…

Students' epistemological beliefs have been confirmed to influence students' physics learning in an essential way. The Colorado Learning Attitudes about Science Survey (CLASS) is an assessment instrument for evaluating students' beliefs towards physics learning. In the present study, 817 students participate in our investigation with the mandarin…

This paper describes an experience based on the use of an active method in which students of a basic physics course prepare multiple choice questions (MCQs) to prepare for exams in the subject. The objective of the research was to provide the students with a method that would enhance their desire to learn physics, and consequently lead to an…
