Developing Adaptive Expertise to Support All Learners: An Autoethnographic Investigation of my Teaching Journey

Entering the profession with vastly different preparation and perspectives, teachers encounter diverse students, complex contexts, and shifting expectations for which they frequently find themselves underprepared by their preservice training. With greater awareness emerging about the significant effect that individual teachers have on student outcomes, and an understanding that the knowledge and mindsets needed for optimal instruction cannot be fully developed during preservice education, teachers need effective paths for ongoing professional development (PD). Self-directed PD, with its capacity for customization in content and pacing, has the potential to more effectively foster meaningful and continuous teacher learning. Through autoethnographic methods (e.g., Adams et al., 2015; Chang, 2013; Ellis, 2013; Ellis & Bochner, 2000; Holman Jones et al., 2013; Starr, 2010), this study sought to bridge the knowledge gap related to self-directed PD processes by investigating my journey of teacher development. Using the Five Lenses Conceptual Framework I developed based on over two decades of teaching experience and supported by extensive research, and using the theoretical framework of adaptive expertise (e.g., Bransford et al., 2005b; Hammerness et al., 2005; Hatano & Inagaki, 1986; Hayden et al., 2013; Pelgrim et al., 2022), I investigated the development of my identity, roles, and growth over two decades of teaching, and I explored how a systematic PD practice during one specific year facilitated more consistent and effective growth. The study reflects the impact of self-directed, systematic reflective teacher practices that can guide teacher growth in ways that support improved student outcomes. Effective PD paths are essential for educators seeking to be agents of change for students, especially given the complex and frequently shifting challenges of diverse student needs, inconsistent support, and socio-political inequities

Stand-your-ground laws and housing insecurity : boundary-work and intersections in gun laws and housing insecurity

Despite the strong and sustained public reaction to the passage of self-defense statutes known as Stand Your Ground laws, little existing scholarship exists which seeks to investigate the popularity of such laws, which are now applicable in the majority of American states. Utilizing Census, Housing and Urban Development data as well as a unique dataset constructed by Princeton’s Evictionlab project, I analyze the relationship between the presence or absence of SYG laws and housing security, utilizing data from two states that have such laws and two that do not. Because SYG laws are predicated on the Castle Doctrine and the unique moral status of domestic space in the Anglo-American legal tradition, one would expect that some relationship exists between housing security and the successful passage and retention of such laws, though the nature of such a notional relationship has yet to be articulated. This study anticipates that states with greater housing security are more likely to have such laws. I construct a housing insecurity index from four state-level factors (housing tenure, housing cost burden, eviction rate, and homelessness estimate) and find that a multi-dimensional construct of housing insecurity is indeed positively correlated with the presence of such laws, though causal order and direction cannot be inferred from the analyses here performed

Childhood asthma psychomaintenance : a case study of medical noncompliance

This case study has the purpose of investigating the causal factors of childhood psychomaintenance (the perpetuation of chronic illness) . The subject of this case study is a black, asthmatic boy who participated in psychotherapy sessions aimed at discovering his own motivations for being medically noncompliant. Information for this case study was gathered from personal interviews, tape-recorded therapy sessions, medical records, educational records, and psychometric evaluations. The information that has been collected for this case study was presented under the following headings: (1) family structure and personal history, (2) medical data, (3) educational data, (4) psychometric data, and (5) psychological data. This data has been compiled and organized to outline the important characteristics of psychomaintenance. The author has discovered that three factors appear to be highly related to one another and are causative agents of psychomaintenance: family structure, secondary gains, and self-concept. These results were supported by findings in the existing literature. This thesis is also an exercise in interfacing psychology with medicine, with the goal of maximizing behavioral health care potentials. The conclusions are that psychomaintenance must then be evaluated on an individual basis for a useful assessment. This means that psychologists and physicians must share knowledge, and methods which cover the whole person for the benefit of that patient. Finally, then, the field of research and pragmatic implementation of knowledge within the sphere of psychomaintenance can be demonstrated through this case study as a possible example.by Craig Andrew ZacutoIncludes bibliographical references (pages 73-76

Catalytic Transformations of Alkynes via Ruthenium Vinylidene and Allenylidene Intermediates

NOTICE: This is the peer reviewed version of the following book chapter: Varela J. A., González-Rodríguez C., Saá C. (2014). Catalytic Transformations of Alkynes via Ruthenium Vinylidene and Allenylidene Intermediates. In: Dixneuf P., Bruneau C. (eds) Ruthenium in Catalysis. Topics in Organometallic Chemistry, vol 48, pp. 237-287. Springer, Cham. [doi: 10.1007/3418_2014_81]. This article may be used for non-commercial purposes in accordance with Springer Verlag Terms and Conditions for self-archiving.Vinylidenes are high-energy tautomers of terminal alkynes and they can be stabilized by coordination with transition metals. The resulting metal-vinylidene species have interesting chemical properties that make their reactivity different to that of the free and metal π-coordinated alkynes: the carbon α to the metal is electrophilic whereas the β carbon is nucleophilic. Ruthenium is one of the most commonly used transition metals to stabilize vinylidenes and the resulting species can undergo a range of useful transformations. The most remarkable transformations are the regioselective anti-Markovnikov addition of different nucleophiles to catalytic ruthenium vinylidenes and the participation of the π system of catalytic ruthenium vinylidenes in pericyclic reactions. Ruthenium vinylidenes have also been employed as precatalysts in ring closing metathesis (RCM) or ring opening metathesis polymerization (ROMP). Allenylidenes could be considered as divalent radicals derived from allenes. In a similar way to vinylidenes, allenylidenes can be stabilized by coordination with transition metals and again ruthenium is one of the most widely used metals. Metalallenylidene complexes can be easily obtained from terminal propargylic alcohols by dehydration of the initially formed metal-hydroxyvinylidenes, in which the reactivity of these metal complexes is based on the electrophilic nature of Cα and Cγ, while Cβ is nucleophilic. Catalytic processes based on nucleophilic additions and pericyclic reactions involving the π system of ruthenium allenylidenes afford interesting new structures with high selectivity and atom economy
