School choice draws upon market principles for restructuring education as schools compete for student enrollment by appealing to parents. When parents hold the power to choose where--among several options--to enroll their child for learning, they will select the school that best meets their child's academic and social-emotional needs (Cooper,…

Ultrafast laser spectroscopy is a valuable and increasingly accessible technique for studies of rapid chemical reactions. Critical to ultrafast spectroscopy is the concept of mode locking, a technique that enables a fixed phase relationship between laser modes, resulting in laser pulses with very short duration (in the fs or ps range). Despite the…

This brief examines which students in the Houston Independent School District (HISD) are more likely to earn the STEM endorsement and whether STEM endorsement completion predicts college enrollment. Analyses show that gender, STEM magnet program enrollment, and cumulative high school grade point average (GPA) predict STEM endorsement completion.…

A simple experiment is described to verify the current dependence of Ampère's law for a long straight current-carrying conductor. A narrow and long rectangular multi-loop design is used to increase the strength of the magnetic field in between the long sides. As expected, the magnetic field is found to be linearly proportional to the electric…

An alternative way of introducing magnetism at all levels of education is proposed. It is stressed that magnetism can be introduced through the interaction between current-carrying conductors giving the students, at the same time, the possibility to measure the magnetic permeability [mu][subscript o]. Focusing on currents instead of permanent…

In this work, we made a simple electronic tool called a 'magnetic polarity detector' which can determine the magnetic poles of permanent magnets or electromagnets. We used it in some student experiments in the physics laboratory. For example, determining the magnetic poles of permanent magnets and a current-carrying coils or electromagnets.…

The article presents the results of an experimental study on the motion of a neodymium magnet on an inclined duralumin plate. During experiments, the time of motion was measured, and the steady-state velocity of the magnet motion was determined. To measure the time, a robotic set was used, which made it possible to measure the time of the motion…

All physics is fascinating, but some stories are more exciting than others. A story that involves some of the most precise measurements ever made and a tantalizing discrepancy might be one of the most interesting. Throw in a 3200-mile journey, a heavily laden truck covered by a tarpaulin, closed-down highways with police escorts, and hushed…

Joining the chorus of Black/Critical Race Feminist scholarship in education, this article explores how both affect and visuality inform understandings of safety for Black girls in schools. Using participatory visual ethnography, I explore how five young Black women at a Philadelphia magnet school conceptualize safety as an affective achievement of…

In this study, we derived several formulas for the currents induced in a circular loop by a magnet connected to a spring-based simple harmonic oscillation system. In addition, we conducted an experiment for measuring the induced currents and compared the results with the theoretical prediction. It was confirmed that the prediction from the derived…

This study examined the effect of blended laboratory experiments on pre-service physics teachers' (PSPTs') attitudes toward physics laboratories. The research design was a quasi-experimental pre-test and post-test comparing groups. Participants were 63 2nd-year PSPTs' enrolled in a physics diploma program from three colleges of teacher education.…

One of the controversies surrounding charter schools is whether these schools may either "cream skim" high-performing students from traditional public schools or "pushout" low-achieving students or students with discipline histories, leaving traditional public schools to educate the most challenging students. In this study, we…

It is critical to develop students' science communication skills as they progress through their education. One way this goal can be accomplished is by integrating Flip into educational programs. Through Flip educators create prompts that students respond to in video form, which leads to deeper discussion on various topics. This brief will share an…

District and building administrators in the United States are struggling to integrate academic and career and technical education (CTE) as required by Every Student Succeeds Act and Perkins V legislation. One solution school district leaders have developed to address this legislation is the creation of CTE magnet high schools. However,…

School choice options offer potential educational gains for disadvantaged students, but do they take advantage of such options? I study the sorting patterns of students with prior child welfare reports (12 percent of incoming kindergartners) across traditional public, magnet, charter, and private schools in a mid-sized city. These students are…
