Measuring magnetic induction is occasionally performed by our students during their academic training in physics. Among the various methods used to measure it, the Hall effect is the most common and widespread. Another way consists of employing an electronic flux-meter. It is constituted by a small flat coil (SFC) connected to the input of an…

Magnetic resonance is a quantum phenomenon and describes a resonant interaction of spins with electromagnetic fields. Its understanding requires advanced knowledge of quantum mechanics and condensed matter physics and thus often remains elusive to students. However, the great impact of this phenomenon on medicine, science, and technology makes…

Magnets are familiar objects and yet magnetism as a concept remains challenging. A casual search of YouTube for magnets reveals a staggering number of videos, interesting demos involving electric and permanent magnets, and entire channels devoted to various uses for magnets. It is far more difficult to find descriptions that can help students…

Magnet schools have been a main tool or innovation in urban education settings in the United States, originating in the early 1970's and expanding into most large urban districts today (Blank, 1989). While some magnet schools do not rely on a specific criterion to determine entry, many do. This study focuses on such a setting where students must…

In this dissertation I will present my work in both the fields of spintronics and physics education research. In the first section, I present a method to account for spin pumping in spin torque ferromagnetic resonance (ST-FMR) measurements. A spin current can be generated via the spin Hall effect (SHE), which is typically transverse to the charge…

Not enough research has been conducted to determine what can support and encourage successful African-American students in mathematics. Many environmental and personal factors have been identified that may impact the success of African-American students in mathematics but studying and relating these factors at a qualitative level would benefit…

Public-school choice programs have multiplied over the past decades. Previous researchers have analyzed the significant roles that parents play when deciding what they think is best for their children's futures. Though research has shown the roles and factors over parents' educational choices for their student, there are limited studies on student…

Electromagnetism, along with mechanics, is one of the most fundamental disciplines in physics, and the magnetic force is one of the most easily accessible forces existing in nature. Magnets are often used as science teaching aids and are readily available from a young age; the forces of these magnets are first dealt with in NGSS (Next Generation…

Today, nearly three quarters of Miami-Dade students are enrolled in choice programs. That makes Miami-Dade the most choice-rich district in arguably the most choice-rich state. Parents and teachers who live in Miami-Dade now access more than 500 non-district schools that didn't exist or weren't accessible 20 years ago, and everybody knows even…

Two-hour long developmental teaching interviews were conducted with each of 14 sixth grade students, ages 11-12. The purposes of the interviews were to investigate how students solved arrangement problems (APs), and how their solutions of these problems differed from their solution of Cartesian product problems (CPPs). The 14 students represented…

Presently, it is possible to use virtual learning environments for simulating abstract and/or complex scientific concepts. Multimodal Virtual Learning Environments use multiple sensory stimuli, including haptic feedback, in the representation of concepts. Past research on the utilization of haptics for learning has shown inconsistent results when…

School choice is expanding, but the majority of students in countries like the United States still attend the school associated with their residential address. We study assignment policies and reassignments of students, where students apply to attend a magnet school or request to transfer to another school within the public school system.…

Student engagement has been at the forefront of education in all levels. From Pre-Kindergarten to Higher learning, the ways in which students attend during instruction and with tasks can be seen as an indicator of varying levels of student achievement and growth. The Corona Virus of 2019 opened up new questions when examining student engagement.…

It can readily be demonstrated that when a low frequency alternating voltage is applied to an iron-core coil the impedance is much higher than the direct current resistance of the coil. To understand how the high level of impedance arises it is necessary to explain how magnetic and electrical induction give rise to a current in the coil that…

The transformations of electric and magnetic fields are usually introduced by viewing systems such as a long, straight current-carrying wire and a parallel plate capacitor in two different reference frames. These well-known examples show that magnetism is a necessary consequence of augmenting electrostatics with relativity. Because they require…
