<p>This study focused on how physics teachers develop and implement activities that promote creative thinking strategies in the standards based physics classroom. A particular focus was placed on every day or little `c? creativity, which can be taught in the high school classroom. The study utilized a multiple case study design, which allows for in-depth study in a variety of settings. Four participants from various high schools were identified utilizing administrator recommendations. Data were then collected via interviews, observations, and documents. The data were coded and analyzed for emerging themes. The themes were then merged to determine findings to the stated research questions. The research demonstrated the importance of modifying activities for student interest and understanding through effective use of scientific inquiry. The past experiences and professional development of the participants served as a vital piece to the development of their educational pedagogy especially concerning inquiry and questioning strategies. It was also established that an unstructured, positive classroom environment is a vital aspect of teaching while supporting creative thinking skills.

<p> Astronomy is one of the oldest STEM enterprises today. It is a discipline through which technology has been advanced, as well as our understanding of the universe. Further, astronomy is a gateway science that inspires the imagination of young learners, and can be used to promote STEM careers. In order to advance the astronomy enterprise, we must maintain an informed citizenry. The practice of astronomy has changed over time; astronomy today is much different than it was 50 years ago. In an effort to identify the current practice of astronomy, or what it is that today&rsquo;s astronomers do, 478 U.S. astronomers participated in the study focusing on their engagement in three areas of scientific practice; science attitudes, tools and techniques, and social interactions. In addition, astronomers&rsquo; perceptions about career choice, work-related activities they engage in, motivations for doing astronomy, and changes needed in education were also explored. Data were collected over a 3-month time period via an online survey and telephone interviews. Data provided by survey participants provides a solid foundation from which findings and conclusions are drawn. Today&rsquo;s population of astronomers is largely white, male, and older, however moving toward gender balance. The population as a whole places great importance on the practice of attitudes such as thinking critically, respecting the evidence, honesty, and objectivity. Unlike many might think, astronomers spend little time at the telescope collecting data, but rather the vast majority of their time is spent working at a computer. Further, engaging in administrative duties, writing, use of mathematics, searching for funding, mentoring others, and collaborating with colleagues are all critical tools/techniques and social skills in the practice of astronomy today. Finally, pop culture and personal experience plays a significant role in attracting individuals to a career in astronomy, and exploration and uncovering that which is unknown, the thrill of discovery, is what keeps them motivated. This study identified and quantified the activities in which professional astronomers engage, and the findings can be used to design formal and informal learning experiences K through adult to more closely reflect the science of astronomy and the people who engage in the practice.</p><p>

<p> Clinical experiences are an essential part of the training of future nursing professionals. The period of clinical experience aims to develop in the student the necessary skills to practice as a nursing professional, when the academic program ends. This case study aimed to understand the opinion and explore the perception of faculty, clinical instructors, and nursing students on the meaning, contributions and challenges presented during clinical experiences. Among the themes explored in the focus groups were the meaning and importance to learning about the profession of clinical experiences, teaching strategies used during the practice scenarios, didactic relationships developed among students, clinical instructors, and teachers. The goal was to learn from all participants about what they do, their expectations, and the challenges presented during the clinical experiences.</p><p> A qualitative, descriptive and contextual research design was followed, which required conducting six focus groups to collect the information from the perspective of all the participants. Faculty, clinical instructors, and nursing students participated each in two focus groups. Collected data were transcribed, coded and analyzed in order to organize it under themes related to the research framework.</p><p> The qualitative analysis of the focus groups revealed that nursing faculty and clinical instructors perceived clinical experiences as a very important element in the training of nursing students, but that coordination between the academy and practice scenarios is disconnected and needs improvement. They also expressed that they use various learning strategies during the clinical experiences, however, they recognize it needs more structure and suggested mentoring as a strategy to consider. They affirmed that mentoring could contribute positively to enhance the teaching-learning process. Clinical instructors understand they perform mentoring roles, but they would like to have a more defined role and structured process. Nursing students, also, recognized the importance of clinical experiences in their professional training. They expressed the need to improve the communication between the academy and the practice scenarios in order to reduce the levels of anxiety they experience when entering the clinical experiences. Nursing students also expressed the need to consider the use of different teaching strategies, such as mentoring, to improve clinical experiences.</p>

<p> To prepare students to disentangle the complicated environmental, social, and economic challenges exacerbated by the previous generation and propose effective solutions, they need to be taught the necessary knowledge and skills. Education for Sustainability (EfS) is one such modality. Organizations such as the Cloud Institute for Sustainability Education, Shelburne Farms, and the US Partnership for Education for Sustainable Development have opened the doors for EfS in the K-12 education system; however, curriculum to address these standards has not yet fully been developed. Furthermore, EfS curriculum that aligns to state and national standards needs to be written so that teachers can then use it in their courses and cultivate systems thinking skills in all learners. The primary objective of this project is to propose a high school level biology curriculum that uses an EfS lens to enhance core science content. A comparison of five EfS curricular frameworks was conducted and the Cloud Institute for Sustainability Education&rsquo;s EfS Standards &amp; Performance Indicators was selected as the primary reference for the sustainability lens of the forthcoming curriculum. The proposed high school biology curriculum focuses on two Next Generation Science Standards themes: Interdependent Relationships in Ecosystems and Natural Selection and Evolution. This curriculum integrates many EfS themes. The dynamics of systems and change and inventing and affecting the future are the two most prominently explored EfS themes in the curriculum. </p>

<p> Secondary science teachers make many daily decisions in the enactment of curriculum. Although curriculum materials are widely available to address science content, practices, and skills, the consideration that goes into deciding how and whether to use such materials is complicated by teachers&rsquo; beliefs about science, their understandings of school-level accountability and testing measures, and their perspectives on the adolescent students they teach. This study addresses the need to understand how teachers consider multiple forces in their enactment of science curriculum.</p><p> The purpose of this study was to explore the ways that discourses around accountability, science, and science education emerge in the narratives around teachers' decision-making in secondary science classrooms. Using a case study approach, I worked at two school sites with two pairs of science teachers. We established criteria for critical incidents together, then teachers identified critical decision-making moments in their classrooms. We analyzed those incidents together using a consultancy protocol, allowing teachers to focus their thinking on reframing the incidents and imagining other possible outcomes.</p><p> Using post-structuralist rhizomatics, I assembled analyses of teachers&rsquo; discussions of the critical incidents in the form of dramatization&mdash;scenes and monologues. I then developed two major interpretive strands. First, I connected teachers&rsquo; sense of having &ldquo;no time&rdquo; to blocs of affect tied to larger discourses of national security, teacher accountability, and the joy of scientific discovery. Second, I demonstrated how teachers&rsquo; concern in following logical pathways and sequences in science relates to the imposition of accountability measures that echo the outcomes-driven logic of the learning sciences. Across both interpretations, I found accountability to be complex, multidirectional, and unpredictable in how it works on and through teachers as they make decisions.</p><p> Research in this area has important practical implications in the fields of professional development, curriculum development, and school change. As more states (including New York) adopt standards derived from the Next Generation Science Standards (NGSS), the importance of privileging teachers&rsquo; investment and critical decision-making in the process of new curriculum development is vital. I suggest that tools like video-based coaching and consultancy protocol discussions support this kind of thoughtful curricular change.</p><p>

<p> An online curriculum about biological evolution was designed according to the <i>Promoting Evidentiary Reasoning and Self-regulation Online</i> (PERSON) theoretical framework. PERSON is an attempt to develop online science instruction focused on supporting evidentiary reasoning and self-regulation. An efficacy study was conducted with 80 suburban high school biology students using a design-based research approach to develop a curriculum to promote biological evolution understandings, evidentiary reasoning, and self-regulation. Data sources and instruments included (1) the Biological Evolution Assessment Measurement (BEAM); (2) the modified <i>Motivated Strategies for Learning Questionnaire</i> (MSLQ); (3) discussion forum posts; (4) formative assessments of evidence based reasoning; (5) <i> Prediction, Monitoring, and Reflection</i> forms (PMR); (6) the <i> Online Instruction Questionnaire</i>; and (7) field notes. Findings revealed that BEAM posttest scores were significantly greater than pretest scores for items designed to measure biological evolution content knowledge and evidentiary reasoning. Students tracked in a lower level biology course showed improvement in biological evolution understandings and evidentiary reasoning. It was found that performance on daily evidentiary reasoning tasks strongly predicted BEAM posttest scores. However, findings revealed that students did not meet local standards for performance on items designed to measure evidentiary reasoning. Students expressed a variety of opinions about their learning experiences with the online curriculum. Some students expressed a definite preference for traditional learning environments, while others expressed a definite preference for online learning. Self-regulatory ability did not significantly predict BEAM gain scores. Further, self-regulatory ability was not demonstrably improved as a result of this intervention. Implications for designing science instruction in asynchronous online learning environments to support evidentiary reasoning and self-regulation are discussed.</p>

<p> Modeling is an important scientific practice through which scientists generate, evaluate, and revise scientific knowledge, and it can be translated into science classrooms as a means for engaging students in authentic scientific practice. Much of the research investigating modeling in classrooms focuses on student learning, leaving a gap in understanding how teachers enact this important practice. This dissertation draws on data collected through a model-based curricular project to uncover instructional moves teachers made to enact modeling, to describe factors influencing enactment, and to discuss a framework for designing and enacting modeling lessons. </p><p> I framed my analysis and interpretation of data within the varying perceptions of modeling found in the science studies and science education literature. Largely, modeling is described to varying degrees as a means to engage students in sense-making or as a means to deliver content to students. This frame revealed how the instructional moves teachers used to enact modeling may have influenced its portrayal as a reasoning practice. I found that teachers&rsquo; responses to their students&rsquo; ideas or questions may have important consequences for students&rsquo; engagement in modeling, and thus, sense-making. </p><p> To investigate factors influencing the portrayal of modeling, I analyzed teacher interviews and writings for what they perceived affected instruction. My findings illustrate alignments and misalignments between what teachers perceive modeling to be and what they do through instruction. In particular, teachers valued providing their students with time to collaborate and to share their ideas, but when time was perceived as a constraint, instruction shifted towards delivering content. Additionally, teachers&rsquo; perceptions of students&rsquo; capacity to engage in modeling is also related to if and how they provided opportunities for students to make sense of phenomena. </p><p> The dissertation closes with a discussion of a framework for designing and enacting lessons for engaging students in modeling. I draw on examples from this study to provide context for how the framework can support teachers in engaging students in modeling. Altogether, this dissertation describes how teachers facilitate modeling and why varying enactments may be observed, filling a gap in researchers&rsquo; understanding of how teachers enact modeling in science classrooms.</p><p>

<p> This research evaluates the effectiveness of Project ReCharge, an energy efficiency, STEM curriculum designed for middle and high school students. The project includes a five-unit curriculum, and monthly professional development spanning a year. The project was implemented in ten schools over three years. Four areas were explored in the study including (1) changes to student content knowledge, (2) changes to student attitudes towards STEM subjects and careers, (3) changes to teacher self-efficacy and beliefs, and (4) changes to teacher content knowledge. A content test for teachers and students, the STEM Semantics Survey, and STEBI-A were used to collect data on 4123 students and 47 teachers. Data were collected in a quasi-experimental design utilizing parametric and nonparametric techniques. Analyses suggest student content knowledge increased significantly from pretest to posttest for all years (Pretest: <i>M</i> = 11.38, <i>SD</i> = 4.97, Posttest: <i>M</i> = 16.67, <i> SD</i> = 5.83, <i>t</i> = 45.05, <i>p</i> &lt; 0.001, <i> d</i> = 0.98). Increases to student attitudes in STEM varied by year and grade, but overall increases were found in science (<i>N</i> = 2362, <i>z</i> = &ndash;2.618, <i>p</i> = 0.030, &eta;² = 0.002), and math attitudes (<i>N</i> = 2348, <i> z</i> = &ndash;2.280, <i>p</i> = 0.023, &eta;² = 0.002). High school students tended to show more increased attitudes in more subject areas than middle school students. No changes to teacher self-efficacy and beliefs were found, and increases to teacher content knowledge only occurred in the third year (<i>N</i> = 22, <i>x</i>² = 5.158; <i>p</i> = 0.076, &eta;² = 0.319).</p><p>

<p> Within the confines of this study, the researcher investigated Project Lead the Way (PLTW) Engineering curriculum goals within Missouri high schools. The study measured Missouri PLTW teachers&rsquo; perceptions of various elements of the curriculum as well as state and national PLTW End of Course student assessment data to determine if a relationship existed between teachers&rsquo; perceptions of curriculum implementation and student performance, as measured through Missouri End of Course exams in various secondary engineering classes. In addition, the researcher conducted voluntary interviews with teachers, state administrators, and national representatives of PLTW to inquire about experiences with the PLTW Engineering curriculum. </p><p> Qualitatively, Missouri PLTW Engineering teachers expressed varied levels of satisfaction through a survey generated by the researcher, based upon national curriculum goals established by PLTW. Within the study, teachers&rsquo; perceptions reported students&rsquo; abilities to identify, formulate, and solve engineering problems were greater than students&rsquo; abilities to design and conduct experiments, as well as to demonstrate knowledge of and responsibility for engineering issues, including ethical and professional responsibilities. The researcher attributed this perception to students&rsquo; lack of professional experience and to PLTW curriculum not providing enough opportunities for students to gain real-world relevant experience using the content and strategies learned during instructional class time. </p><p> The intention of this study was to provide a framework to review and evaluate curriculum goals established by PLTW, Inc. Originally, the researcher looked at national goals for the program to determine the outcomes of PLTW&rsquo;s educational programming. However, much of the data was post-secondary related and the researcher wanted to maintain the quantitative nature of the study. Nonetheless, research could expand upon the framework to study any state in the nation through either a mixed-methods approach or the use of a quantitative study approach. The researcher recommends further research be conducted either by PLTW, Inc., through state PLTW affiliates or by other individuals to determine future outcomes of educational curriculum offered by PLTW. This could include engineering, biomedical science, computer science, middle school curriculum offered through Gateway to Technology (GTT), or through elementary curriculum offered through Launch.</p><p>
