Description
Virtual Patient Simulations (VPS) are web-based exercises involving simulated patients in virtual environments. This study investigates the utility of VPS for increasing medical student clinical reasoning skills, collaboration, and engagement. Many studies indicate that VPS provide medical students with essential practice in clinical decision making before they encounter real life patients. The utility of a recursive, inductive VPS for increasing clinical decision-making skills, collaboration, or engagement is unknown. Following a design-based methodology, VPS were implemented in two phases with two different cohorts of first year medical students: spring and fall of 2013. Participants were 108 medical students and six of their clinical faculty tutors. Students collaborated in teams of three to complete a series of virtual patient cases, submitting a ballpark diagnosis at the conclusion of each session. Student participants subsequently completed an electronic, 28-item Exit Survey. Finally, students participated in a randomized controlled trial comparing traditional (tutor-led) and VPS case instruction methods. This sequence of activities rendered quantitative and qualitative data that were triangulated during data analysis to increase the validity of findings. After practicing through four VPS cases, student triad teams selected accurate ballpark diagnosis 92 percent of the time. Pre-post test results revealed that PPT was significantly more effective than VPS after 20 minutes of instruction. PPT instruction resulted in significantly higher learning gains, but both modalities supported significant learning gains in clinical reasoning. Students collaborated well and held rich clinical discussions; the central phenomenon that emerged was "synthesizing evidence inductively to make clinical decisions." Using an inductive process, student teams collaborated to analyze patient data, and in nearly all instances successfully solved the case, while remaining cognitively engaged. This is the first design-based study regarding virtual patient simulation, reporting iterative phases of implementation and design improvement, culminating in local theories (petite generalizations) about VPS design. A thick, rich description of environment, process, and findings may benefit other researchers and institutions in designing and implementing effective VPS.

Description
Four Souvenirs for Violin and Piano was composed by Paul Schoenfeld (b.1947) in 1990 as a showpiece, spotlighting the virtuosity of both the violin and piano in equal measure. Each movement is a modern interpretation of a folk or popular genre, re- envisioned over intricate jazz harmonies and rhythms. The work was commissioned by violinist Lev Polyakin, who specifically requested some short pieces that could be performed in a local jazz establishment named Night Town in Cleveland, Ohio. The result is a work that is approximately fifteen minutes in length. Schoenfeld is a respected composer in the contemporary classical music community, whose Café Music (1986) for piano trio has recently become a staple of the standard chamber music repertoire. Many of his other works, however, remain in relative obscurity. It is the focus of this document to shed light on at least one other notable composition; Four Souvenirs for Violin and Piano. Among the topics to be discussed regarding this piece are a brief history behind the genesis of this composition, a structural summary of the entire work and each of its movements, and an appended practice guide based on interview and coaching sessions with the composer himself. With this project, I hope to provide a better understanding and appreciation of this work.

Description
Samuel Máynez Prince (1886-1966), was a prolific and important Mexican musician. Prince’s musical style followed the trends of the nineteenth-century salon music genre. His compositions include lullabies, songs, dances, marches, mazurkas, waltzes, and revolutionary anthems. Prince’s social status and performances in the famed Café Colón in Mexico City increased his popularity among high-ranking political figures during the time of the Mexican Revolution as well as his status in the Mexican music scene.
Unfortunately there is virtually no existing scholarship on Prince and even basic information regarding his life and works is not readily available. The lack of organization of the manuscript scores and the absence of dates of his works has further pushed the composer into obscurity. An investigation therefore was necessary in order to explore the neglected aspects of the life and works of Prince as a violinist and composer. This document is the result of such an investigation by including extensive new biographical information, as well as the first musical analysis and edition of the complete recovered works for violin and piano.
In order to fill the gaps present in the limited biographical information regarding Prince’s life, investigative research was conducted in Mexico City. Information was drawn from archives of the composer’s grandchildren, the Palacio de Bellas Artes, the Conservatorio Nacional de Música de México, and the Orquesta Sinfónica Nacional. The surviving relatives provided first-hand details on events in the composer’s life; one also offered the researcher access to their personal archive including, important life documents, photographs, programs from concert performances, and manuscript scores of the compositions. Establishing connections with the relatives also led the researcher to examining the violins owned and used by the late violinist/composer.
This oral history approach led to new and updated information, including the revival of previously unpublished music for violin and piano. These works are here compiled in an edition that will give students, teachers, and music-lovers access to this unknown repertoire. Finally, this research seeks to promote the beauty and nuances of Mexican salon music, and the complete works for violin and piano of Samuel Máynez Prince in particular.

Description
Learning analytics application is evolving into a student-facing solution. Student-facing learning analytics dashboards (SFLADs), as one popular application, occupies a pivotal position in online learning. However, the application of SFLADs faces challenges due to teacher-centered and researcher-centered approaches. The majority of SFLADs report student learning data to teachers, administrators, and researchers without direct student involvement in the design of SFLADs. The primary design criteria of SFLADs is developing interactive and user-friendly interfaces or sophisticated algorithms that analyze the collected data about students’ learning activities in various online environments. However, if students are not using these tools, then analytics about students are not useful. In response to this challenge, this study focuses on investigating student perceptions regarding the design of SFLADs aimed at providing ownership over learning. The study adopts an approach to design-based research (DBR; Barab, 2014) called the Integrative Learning Design Framework (ILDF; Bannan-Ritland, 2003). The theoretical conjectures and the definition of student ownership are both framed by Self-determination theory (SDT), including four concepts of academic motivation. There are two parts of the design in this study, including prototypes design and intervention design. They are guided by a general theory-based inference which is student ownership will improve student perceptions of learning in an autonomy-supportive SFLAD context. A semi-structured interview is used to gather student perceptions regarding the design of SFLADs aimed at providing ownership over learning.

Description
In this study, the current literature regarding student engagement and student voice were reviewed to explore the connection between these two classroom elements. Currently, frequently incorporating student voice in order to increase student engagement most commonly takes place at the high school and university levels. Thus, utilizing Finn’s (1989) participation-identification theory, this study set out to implement a practical design intervention in an elementary classroom to increase student engagement through the incorporation of student voice. Using Design-Based Research, I implemented a collaborative reflection process which allowed students, teacher/researcher, and co-educators to provide feedback on classroom task and participant structures. The feedback was then considered for further iterations of the task and participant structures. This was a pilot study of the collaborative reflection process and was implemented in a fourth-grade math classroom with 26 participants. Along with participating in the collaborative reflection process, the student participants also took a 26 question Learner Empowerment Measure to survey their feelings of identity with the classroom before and after the design intervention. After analyzing audio data gathered during the classroom tasks, as well as student feedback, it was found that student participation did increase due to the design intervention. However, there was no measurable difference in students’ feelings of identity with the classroom due to the collaborative reflection process. Future studies should consider implementing the collaborative reflection process in multiple classrooms across diverse activities during the school year.

Description
This qualitative, design-based research study explored the design, implementation, and outcomes of a professional development for mid-career K-8 science and engineering teachers. The Responsive and Empowering Science and Engineering Teacher (RESET) professional development was designed to support teachers in developing role identities as culturally responsive teachers, change agents disrupting inequitable educational practices, and advocates of students’ equitable access to and participation in science and engineering disciplines. Four mid-career K-8 teachers participated in RESET, which was embedded in a five-week summer program focused on solar energy engineering. The teachers engaged in activities designed to increase their knowledge of and pedagogical strategies for culturally responsive teaching. After each key event, teachers reflected on their experiences in terms of their role identities, including their purposes and goals, self-perceptions, beliefs, and perceived action possibilities for that role. Teachers also engaged in critical discussions examining how the strategies and practices might contribute to more equitable science and engineering practices. An embedded case study design was used, with RESET as the focal case and the four teachers as embedded cases, to examine teachers’ experiences during RESET and actions during the school year. I analyzed teacher surveys, semi-structured interviews, written reflections, audio recordings of the critical discussions, and researcher memos from during RESET and school year observations to determine the influence of RESET on teachers’ role identity development and actions. I also analyzed a series of conjecture maps created to detail the design and adaptations of RESET to explore the extent to which RESET’s targeted enactment processes and outcomes had been achieved and design and process conjectures had been supported. Findings varied across participants, with all four participants at least somewhat achieving the targeted outcomes, indicating that all of the teachers’ role identities were influenced by RESET. Three of four teachers translated their learning into actions as culturally responsive science and engineering teachers during the school year. In terms of RESET’s design, several of the conjectures were supported or partially supported. Implications for the second iteration of RESET and for the general scholarship on professional development for mid-career K-8 science and engineering teachers are discussed.

Description
Today’s science education has been highly criticized in the United States despite reform efforts that attempt to promote more wholistic and integrated goals for teaching and learning science, which include both the understanding of key content and the acquisition of scientific skills. Outdoor education may be a means with which to better engage students in science, but educators often find this type of teaching difficult to adopt for a variety of reasons. Nature journaling may be a useful access point to outdoor education for teachers experiencing those barriers. This study examines a six-month implementation of nature journaling activities in a high school Ecology & Animal Behavior course. It was found that students completing nature journaling in this classroom utilized both scientific knowledge and scientific practices in their work, and that instances and depth of these demonstrations increased as a general trend over time, which may be considered successful learning according to situativity theory. Further, students communicated their understanding of what they were accomplishing through their journal work as highly beneficial, though their own perceptions of their competencies in scientific practices did not change. Though additional research needs to be conducted, this study points to a potentially positive relationship between modern science education and outdoor learning through nature journal activities.
