School closures during the COVID-19 pandemic have resulted in substantial learning gaps in students' mathematical abilities. The problem was self-enrollment against teacher recommendation among Honors Algebra 2 students in 9th, 10th, and 11th grade students at a local high school. The purpose of the quantitative, quasi-experimental study was to…

High schools sought to meet the demands of physical distancing and movement restrictions due to COVID-19. Given this unexpected situation, the researcher designed a quasi-experimental ex-post facto study to compare student outcomes from the Pennsylvania Keystone Examinations for Biology and Literature delivered in face-to-face (F2F) and virtual…

This qualitative study explored Latina/o students' sense of belonging in majority White and Asian Advanced Placement (AP) and honors classes in a diverse suburban high school. Using self-determination theory as a framework, I focused on three aspects of sense of belonging: social belonging, teacher-student relationships, and academic belonging.…

Although most of the writing in high school English Language Arts (ELA) classrooms is about literature and although there have been incessant calls for changing the practices of teaching and learning literature, only meager amounts of research have been conducted in these interrelated domains of the field. Accordingly, this dissertation seeks to…

We devised a half-day laboratory exercise for a group of 10th grade homeschooled students enrolled in an honors-level high school general chemistry course organized by a collective of homeschooling families associated with local Christian churches. Anecdotal evidence suggested that the students met the learning objectives of the exercise. The…

Background/Context: There is broad agreement about the benefits of taking AP and/or IB courses in high school. Nonetheless, student access to such courses remains uneven and inequitable, due largely to the practice of tracking students by perceived "ability." These tracking practices are often defended based on the contention that…

In this design case, we describe our work to design and develop a socio-scientific issue (SSI) based unit of instruction for use in high school biology. Our team includes university based science educators, an experienced classroom teacher, and a microbiologist. The unit focuses on antibiotic resistant bacteria as a context for student exploration…

This dissertation investigates the impact reading Young Adult Literature (YAL) has on students' empathetic responses as well as their capacity to take action regarding a social justice issue chosen by the student. Drawing on data from a 10th grade honors classroom at a Title 1 school in the Southwest, this ethnographic case study investigates how…

Though the students at Appoquinimink High School (AHS) earned the fifth highest scores on DCAS Reading (among traditional public high schools), I was skeptical regarding whether these results accurately represented our students' literacy proficiency. My classroom interactions suggested that students lacked motivation toward literacy. Specifically,…

Public schools are examining their policies and instructional practices to address the achievement gap exposed by the reporting requirements of NCLB (Wenglinski, 2004). As accountability measures and stakes rise, there is a call for an improved use of scientific evidence to inform educational policymaking (Wiseman, 2010). In terms of the…

"A Tale of Four Electrons" is a creative writing assignment used with 10th-grade Honors Chemistry students. The project helps students consolidate their learning about bonding--an important unifying theme in chemistry--and answers questions such as (1) How are ionic, metallic, and covalent bonds related? (2) How do variations in electron…

While there is great deal of research that tracks self-regulatory academic beliefs and behaviors of students, relatively few efforts examine the specific self-beliefs of high achieving African American students. This study compared the intelligence-related beliefs, efficacy beliefs and academic goal orientations of 257 African American (N = 196)…

Conversations with Josh, a mentee of the author, and other gifted students caused the author to realize that in many cases, what is presented as appropriately differentiated language arts curriculum for gifted/talented students is nothing more than general education curriculum with additional work at the same level as the regular curriculum. If…

This study investigated convergent validity evidence for student growth scores with high school course grades. The Measures of Academic Progress and Educational Planning and Assessment System growth scores for approximately 1,800 ninth-grade students over 2 years were related to language, arts, and mathematics course grades for developmental,…

One of the important phenomena observed in the learning of mathematics is compartmentalization. This phenomenon occurs when a learner has two different, potentially contradictory schemes in his or her cognitive structure; in a typical case, a student deals with the same mathematical concept in an inconsistent or incoherent way, or activates a less…
