Amplifying The "A" In Steam Education, Grace Floerke

Honors College Theses

This paper discusses the importance of teachers implementing STEAM education in the classroom. Previously, science, technology, engineering, and mathematics (abbreviated as STEM) education was used as a tool to prepare students to excel in career fields that are projected to grow in the near future. However, recently the acronym was changed to STEAM to add “the arts” to the original acronym. It is imperative that the arts are seen as an equal to STEM, as they can complement and enhance the goals STEM is trying to reach. Since not all students possess the same interest, ways of learning, or abilities, …

How Do Beliefs Come Into Play? An Examination Of The Influence Of Core Conceptions On Science Teachers’ Inquiry Lesson Plan Designs, Mehmet Fatih Dulger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Teaching science through inquiry-based methodologies has been advocated by several governmental and professional organizations (National Research Council [NRC], 2000; NGSS Lead States, 2013); however, their use is not widespread. Why is this? What science teachers do in their classrooms is shaped by their beliefs, especially their beliefs about the nature of science, about the goals and purposes of school science and the goals of teaching science, and about the teaching and learning science. By critically examining these core conceptions and their influence on teacher lesson planning, this study aims to shed light on the role conceptions play when teachers design …
