The United States public schools promote inclusion and educational equity among diverse student populations. Considerable and growing numbers of students with categorical disabilities and Limited English Proficiency (LEP) are enrolled in regular classrooms. The systemic barriers in learning that they have could impact teacher perceptions and decisions about teaching practices as well as the teaching profession. These students have challenged K-12 science, technology, engineering, and mathematics (STEM) teachers to provide high-quality, accommodative service and equitable educational opportunities in an increasingly STEM-infused society. Professional development associated with teaching students with disabilities and LEP is critical to inform in-service STEM teachers with these students' learning needs and promote student success. Effective preparation and support help maintain teacher satisfaction and retention within the teaching profession. However, the levels and perceptions of STEM teacher participation in such professional development, and whether the service load and professional development regarding the concerned groups of students associated with teacher satisfaction and retention remain unclear. This dissertation addresses these issues through two research studies using secondary analysis of the 2011-2012 School and Staffing Survey Teacher Questionnaire (SASS TQ) national dataset. The first study focused on K-12 STEM educator participation and perceived utility regarding their professional development experience concerning students with disabilities and LEP. Quantitative analysis revealed an overall lower level of participation and perceived utility of such professional development for STEM educators compared to all other educators. The second study examined teacher satisfaction and intent to remain in teaching, as well as their relationships to teacher service load and professional development specific to students with disabilities and LEP. Results indicated that K-12 STEM educators were less likely to feel satisfied or intent on remaining in teaching, compared to the remainder of the teaching population. Logistic regressions showed that service load of students with LEP predicted teacher satisfaction and participation in professional development concerning students with disabilities associated with teacher intent to remain in STEM education, especially for science educators. These findings collectively suggested the necessity and demands of sufficient and useful professional development offerings regarding the two concerned groups of students in inclusive STEM education settings. / Ph.

In Deutschland und den USA engagiert sich die unternehmerische Philanthropie zunehmend in der Allgemeinbildung, während der letzten Dekade vor allem in den „MINT“ und den „STEM“ Fächern. Hierzu gibt es bisher kaum systematische Studien. Diese vergleichende Arbeit untersucht, warum und wie sich Unternehmen in diesen Bereichen engagieren, und wie sich ihre Rolle in der Bildung verändert. Die Studie beruht auf einer historischen Analyse der Rolle von Unternehmen in der Bildung seit 1945 und auf Interviews mit Experten aus dem MINT- und STEM-Bereich. Die wichtigsten Befunde der Studie sind: (1) Zuvor überwiegend in der dualen Bildung aktiv, begannen deutsche Unternehmen in den frühen 2000er Jahren u.a. als Reaktion auf den PISA-Schock, sich philanthropisch in der allgemeinen Schulbildung zu engagieren. (2) Unternehmerische Philanthropie führten die MINT und STEM Bildungsbewegung an. Aufgrund ihrer etablierten, gut vernetzten und vielfach finanzkräftigeren Stiftungen gelang es US-amerikanischen Unternehmen besser als deutschen, das Thema ins öffentliche Bewusstsein zu rücken, Ressourcen zu erschließen und Änderungen in der Bildungspolitik zu erwirken. (3) Unternehmen und deren Stiftungen wurden in erster Linie durch Entwicklungen auf dem Arbeitsmarkt, langfristige ökonomische Überlegungen und die Notwendigkeit zur Innovation motiviert, sich zu engagieren; aufgrund unterschiedlicher demographischer Aspekte und Entwicklungen in der Bildung fanden sich Unterschiede zwischen den beiden Ländern. (4) In Deutschland und den USA agiert die unternehmerische Philanthropie zunehmend strategisch, d.h. sie handelt ergebnisorientiert und achtet auf Skalierbarkeit ihrer Aktivitäten. Dies hat das Engagement von Unternehmen in der Bildungspolitik verstärkt und die Anforderung der Wirtschaft in den Fokus gerückt. Manche US-amerikanische Unternehmen haben begonnen, Berufsbildungswege zu schaffen, was bisher nicht die Regel war. / Corporate philanthropy is active in K-12 education in Germany and the U.S. but there is minimal research about it. Over the last decade corporate philanthropic actors in both countries have become active in STEM* education (in Germany, MINT). This comparative study is about why and how they decided to invest in these initiatives and how that is tied to their traditional roles in education. It leans on the history of company involvement in education since 1945 and on interviews with experts active in the STEM and MINT education scenes. The main findings are: (1) As a result of the PISA shock and other factors, German companies that traditionally engaged only in vocational education have become active in general K-12 education. (2) Corporate philanthropy led the STEM and MINT education movements. However, U.S. companies and their foundations, with decades of philanthropic experiences and networks in education, were more successful in raising awareness, organizing resources, and achieving policy changes at the federal level. (3) Companies and their foundations were driven to invest in STEM and MINT education largely by workforce, long-term innovation, and economic concerns but there were key differences because of the differing demographic and education trends in the two countries. (4) In the U.S. and Germany, corporate philanthropy is attempting to be more strategic. This has resulted in a focus on outcome-based measurements and scalability but has also led to more investments in nonprofit and policy organizations instead of schools or their booster clubs. It has also resulted in corporate philanthropy better aligning with company competencies and needs, which made STEM and MINT ideal. In the case of the U.S., this has also resulted in some companies creating vocational programs, an area of education most companies avoided in the past. *STEM= Science, Technology, Engineering, and Math MINT= Mathematik, Informatik, Naturwissenschaften und Technik

Esta investigación es una revisión y análisis documental que permitió reflexionar en torno a los desafíos culturales, tecnológicos y curriculares que la educación STEM1 presenta en Occidente, específicamente en la formación primaria. Así mismo, se quiere abrir nuevas líneas de indagación en torno a un marco conceptual para lo que sería un análisis más detallado y minucioso sobre la temática estudiada. Esta propuesta es creada desde la iniciativa de enseñar las ciencias y matemáticas desde un aprendizaje activo; donde se busca que los estudiantes puedan realizar algunas indagaciones científicas y hacer uso de la tecnología como un recurso conveniente en las experiencias de aprendizaje. En la investigación se podrán observar las aproximaciones al concepto de STEM, así como los desafíos y algunas experiencias de aplicación en docentes del grado primaria. / This research is a documentary review and analysis that allowed us to reflect on the cultural, technological and curricular challenges that STEM education presents in the West, specifically in primary education. Likewise, it wants to open new lines of inquiry around a conceptual framework for what would be a more detailed and thorough analysis of the subject matter studied. This proposal is created from the initiative of teaching science and mathematics from active learning; where it is sought that students can carry out some scientific inquiries and make use of technology as a convenient resource in learning experiences. In the investigation, the approaches to the STEM concept will be observed, as well as the challenges and some experiences of application in primary grade teachers. / Trabajo de investigación

<div> <div> <div> <p>Previous work has identified the many difficulties that students experience in learning abstract concepts in STEM. Past studies have also identified the critical role that emotions play on students' motivation to learn. As new learning technologies are developed, they enable visualizing complex scientific concepts which can be non-visible thus assisting students' understanding of abstract ideas as well as improving their motivation as they learn. This study investigated two learning technologies and compared them to examine 1) their effectiveness on learning concepts of electricity in physics and 2) the interplay between learning with technology and emotions. Participants were randomly assigned to either Inquiry-Based Learning (IBL) with a computer simulation or Game-Based Learning (GBL) with a computer game which addressed concepts of electricity in physics. During the experiment, students in the IBL condition explored materials by using the computer simulation and posed hypotheses and questions on their own with a guiding worksheet for IBL. Students in the GBL condition played an educational computer game following the guiding worksheet while they were meeting challenges created by the game with a guiding worksheet for GBL. Students' learning gains were assessed by comparing their pretest and posttest scores. Emotions were self-reported after the posttest by responding to a survey that measured 6 emotional scales that students may perceive during the experiment. The study found that both IBL and GBL enhanced students' understanding of given concepts. However, there was no statistically significant difference between the two conditions in terms of learning gains. Students in the IBL achieved higher mean learning gains, whereas students in the GBL showed that they were more engaged. At the same time, students in the GBL perceived more confusion and frustration compared to students in the IBL. <br></p> </div> </div> </div>
