A Systematic Literature Review on STEM Education for Mathematics and Science Pre-Service Teachers
The integration of science, technology, engineering, and mathematics (STEM) into educational systems has grown rapidly in international research. The literature reports on policies, experiences, and programs focused on interdisciplinary STEM integration around the world, as well as the challenges that the approach represents for the integration processes that teachers may undertake. Teachers, then, play a key role in the implementation of STEM Education in the school system. This systematic literature review analyzed the strategies for STEM Education of future mathematics and science teachers and the purposes for which they have been incorporated in both research and teacher education. The review considered peerreviewed studies published in the period 20122021 written in Spanish, English, and Portuguese. The review followed a threestep process: planning, conducting and reporting the review. The results show the roles that STEM Education has played in teacher education, both in research and the design of preparation programs. The methodological strategies for preparing future teachers are also reported. Finally, the review provides evidence of the opportunities offered by including STEM Education approaches in early teacher education, regarding the impact on their perceptions, conceptual knowledge, selfefficacy, and future practices.
Estudio de fenómenos físicos en la formación inicial de profesores de Matemáticas. Una experiencia con enfoque STEM
La literatura reporta que los conocimientos para identificar conexiones entre las disciplinas al momento de orientar los procesos educativos se reconocen como una limitante, pese al interés de los profesores de matemáticas por integrar la educación STEM. En ese sentido, se diseñó y fundamentó una experiencia en educación STEM que integró, por medio de la modelación matemática, las matemáticas en contextos de las ciencias (física) y la tecnología. La experiencia se analiza a partir de una metodología cualitativa con enfoque interpretativo. Se utiliza el análisis de contenido para estudiar los significados de las matemáticas que se amplían en el análisis del modelo del fenómeno físico, integrando termómetros y simulaciones computacionales. Los resultados informan que la experiencia permitió que los futuros profesores alcanzaran reflexiones didácticas que reflejan un nivel de preparación y potencial que puede favorecer la integración de la educación STEM en su futuro ejercicio profesional; además, se reportan los alcances y limitaciones de esta experiencia.
