In this study, we provide a review of the status of science and technology education. It addresses the achievements of students in Israel who attend high schools with student bodies that are primarily Arabic speaking. It is generally recognized that the achievements of the Israeli students in international examinations are relatively low. When…

The Divertor Erosion and Vapor Shielding Experiment (DEVEX) has been constructed in the Center for Plasma-Material Interactions at the University of Illinois at Urbana-Champaign. It consists of a conical theta-pinch connected to a 60 kV, 36 [mu]F capacitor bank which is switched with a rise time of 3.5 [mu]s. This results in a peak current of 300…

This dissertation examines the effect of Coulomb interactions in Hanbury Brown-Twiss (HBT) type experiments with electrons. HBT experiments deal with intensity interference, which is related to the second-order correlation function of the particle field. This is an extension of the usual amplitude interference experiment, such as Young's…

We present an introduction to and a tutorial on the properties of the recently discovered ideal circuit element, a memristor. By definition, a memristor M relates the charge "q" and the magnetic flux [phi] in a circuit and complements a resistor R, a capacitor C and an inductor L as an ingredient of ideal electrical circuits. The properties of…

Newton's law of gravitation is a central topic in the first-year physics curriculum. A lecturer can go beyond the physical details and use the history of gravitation to discuss the development of scientific ideas; unfortunately, the most recent chapter in this history, general relativity, is not covered in first-year courses. This paper discusses…

A question we posed in a recent final examination has uncovered a fundamental difficulty for students in understanding destructive interference. The problem stated that glass of index n[subscript 3] was coated with a thin film of a substance with index n[subscript 2]. The question then asked the student to calculate (a) the minimum coating…

Turning lectures into interactive, student-led question and answer sessions is known to increase learning, but enabling interaction in a large class seems an insurmountable task. This can discourage adoption of this new approach -- who has time to individualize responses, address questions from over 200 students and encourage active participation…

In spite of the commendations for the use of portfolio assessment, there is still little evidence indicating that such assessment actually supports and encourages student learning. Hence, this research study aimed to empirically identify the effects of implementation of portfolio assessment on student learning and attitudes. True-experimental…

A "Framework for K-12 Science Education" identified eight practices as "essential elements of the K-12 science and engineering curriculum" (NRC 2012, p. 49). Most of the practices, such as Developing and Using Models, Planning and Carrying Out Investigations, and Analyzing and Interpreting Data, are well known among science…

This study aims to design and develop an interactive software for teaching and learning physics about motion and vectors analysis. This study also assesses its effectiveness in classroom and assesses the learning motivation of SMA Pekanbaru's students. The software is developed using ADDIE Model design and Life Cycle Model and built using the…

Technology-rich student-centered classrooms such as SCALE-UP and TEAL are designed to actively engage students. We examine what happens when the design of the classroom (conventional or teacher-centered versus student-centered classroom spaces) is consistent or inconsistent with the teacher's epistemic beliefs about learning and teaching…

Traditional science instruction is typically reliant on visual modes of learning, such as textbooks and graphs. Furthermore, since science instruction is often heavily dependent upon visual cues, students with visual impairment often do not have access to the same educational opportunities in most science classes (Jones, Minogue, Oppewal, Cook,…

This study focuses on 15 foreign-born students majoring in physics who are also racial/ethnic minorities. We address the research question: What are the acculturation experiences of foreign-born Students of Color majoring in physics? Berry's (2003) theory of acculturation and Bandura's (1994) theory of self-efficacy were substantive…

Several researches identified that many students find physics the most difficult science subject. The quest to find ways to make learning physics more meaningful and interesting has lasted for decades. Even with all the new strategies and pedagogies being used, many students still find the subject formidable. This study critically explored the…

A physics master's degree provides the recipient with a variety of career options. Some master's recipients will continue their education at the graduate level in physics or another field, where others enter the workforce pursuing a wide range of employment opportunities. This "Focus On" provides an in-depth analysis of physics…
