High School Students' Views Of Science In A University Science Internship With Cogenerative Dialogues, Gabriel M. Hayes
High School Students' Views Of Science In A University Science Internship With Cogenerative Dialogues, Gabriel M. Hayes
Open Access Theses & Dissertations
The purpose of this Thesis is to determine how participation in long term university science internships affect nature of science (NOS) conceptual change in high school students. The study was conducted on high school students who volunteered to participate in a seven month university science internship in west Texas. Student views of NOS were measured by pre- and post-internship interviews using five questions about NOS. Internship and no internship student responses were qualitatively analyzed to show change in views of NOS. Findings indicated that participation in long term science internships with cogenerative dialogues improved students conceptualizations of the social dimensions …
Teacher Challenges In Implementing Cognitively Demanding Tasks In The Mathematics And Science Classrooms, Angelica Monarrez Monarrez
Teacher Challenges In Implementing Cognitively Demanding Tasks In The Mathematics And Science Classrooms, Angelica Monarrez Monarrez
Open Access Theses & Dissertations
This mixed methods study examines secondary school mathematics and science teachersâ?? understanding of cognitive demand and the challenges in implementing tasks at different levels of cognitive demand. The conceptual framework for this study is grounded on the conception of cognitive demand proposed by Stein, Smith, Henningsen, and Silver (2000), which includes the following levels: memorization (level 1), procedures without connections (level 2), procedures with connections (level 3), and doing mathematics and science (level 4). The study attempts to address the following research questions: 1) To what extent are secondary mathematics and science teachers able to recognize, solve and construct tasks …
Towards A Unified Theory Of Engineering Education, Oscar Humberto Salcedo
Towards A Unified Theory Of Engineering Education, Oscar Humberto Salcedo
Open Access Theses & Dissertations
STEM education is an interdisciplinary approach to learning where rigorous academic concepts are coupled with real-world lessons and activities as students apply science, technology, engineering, and mathematics in contexts that make connections between school, community, work, and the global enterprise enabling STEM literacy (Tsupros, Kohler and Hallinen, 2009). The purpose of the Dissertation is to develop a unified theory of engineering education based on philosophies of mathematics, science, technology & engineering, and engineering education. Using purposive sampling methods, the Thesis constructs "representative" philosophy statements from the STEM fields based on the criteria of Constructivism, Progressivism, and/or Pragmatism. These statements are …
