Conducted for Arnold Ventures by Abt Associates, the "New Mexico Charter School Study: Findings Report" collates the results of Abt's evaluation of numerous charter schools in the state, several of which employ a whole-school dual language model. The study also created multiple logic models for use by practitioners, policymakers, and…

Schools in the United States continue to be segregated by race and socioeconomic status, almost 70 years after the landmark Brown v. Board of Education ruling that aimed to desegregate schools. Segregation exists in three ways in K-12 schools: (1) Across districts. This is the case in about two-thirds of segregation in metropolitan areas; (2)…

The underrepresentation of women in STEM more generally and in physics specifically has been well established (e.g., Hyater-Adams, Fracchiolla, Finkelstein, & Hinko, 2018; Johnson, Ong, Ko, Smith, & Hodari, (2017); Lock & Hazari, 2016), and the field remains challenged by the negative consequences of this underrepresentation. Women's…

This study explored teachers' experiences in the teaching of electricity and magnetism during a Lesson Study intervention. Using a case study research design, a sample of 4 physical sciences teachers was conveniently selected from schools in rural and suburban areas. Due to logistical challenges, the 4 participants were grouped into 2 separately…

Curriculum Associates' "i-Ready® Instruction" is a supplemental, online personalized instruction program available for reading and mathematics. The Human Resources Research Organization (HumRRO), in collaboration with Century Analytics, implemented a quasi-experimental design (QED) using 2018-19 "i-Ready Diagnostic" and…

Background: Since the passage of "Brown v. Board of Education" in 1954, the demographic landscape of American schools has changed dramatically. By 2011, there were 12.4 million Latinos enrolled in prekindergarten to 12th-grade public schools, which constitutes 23.9% of the U.S. student population. A primary challenge that faces schools…

The construction and operation of a prototype high-"Tc" superconducting train model is presented. The train is levitated by a melt-processed GdBa[subscript 2]Cu[subscript 3]O[subscript x] (Gd-123) superconducting material over a magnetic rail (track). The oval shaped track is constructed in S-N-S or PM3N configuration arranged on an iron…

Despite their physics instructors' arguments to the contrary, introductory students can observe situations in which there seems to be compelling evidence for magnetic force doing work. The counterarguments are often highly technical and require physics knowledge beyond the experience of novice students, however. A simple example is presented…

Questions often arise as to how a device attached to a transformer can draw power from the electrical power grid since it seems that the primary and secondary are not connected to one another. However, a closer look at how the primary and secondary are linked together magnetically and a consideration of the role of Lenz's law in this linkage…

Although the shift from page to screen has dramatically redefined conceptions of writing, very little is known about how youth compose with multiple modes in digital environments. Integrating multimodality and multiliteracies theoretical frameworks, this comparative case study examined how urban twelfth-grade students collaboratively composed…

This article reviews the literature evaluating the impact of school choice programs on racial integration. Evidence on the impacts of magnet schools, voluntary busing programs, open enrollment practices, charter schools, and voucher programs is reviewed. The literature is mixed on this question, finding that the impacts of choice on racial…

Magnet schools focused on science, technology, engineering, and mathematics (STEM) as well as extracurricular programs in STEM support talented students and help increase their participation rates in those domains. We examined whether and the extent to which the learning and educational capital of male and female students (N = 801) enrolled in…

Electromagnetism is an umbrella encapsulating several different concepts like electric current, electric fields and forces, and magnetic fields and forces, among other topics. However, a number of studies in the past have highlighted the poor conceptual understanding of electromagnetism concepts by students even after instruction. This study aims…

This study explored the quality of arguments used by first-year engineering university students enrolled in a traditional physics course dealing with electromagnetic induction and related problem solving where they had to assess whether the electromagnetic induction phenomenon would occur. Their conclusions were analyzed for the relevance of the…

A low-cost chaos dynamics lab is developed for quantitative demonstration of the butterfly effect using a magnetic pendulum. Chaotic motion is explored by recording magnetic time series. Students analyze the data in Excel® to investigate the butterfly effect as well as the reconstruction of the strange attractor using time delay plots. The lab…
