A Study Of Strengthening Secondary Mathematics Teachers’ Knowledge Of Statistics And Probability Via Professional Development, Lina Devaul Aug 2017

A Study Of Strengthening Secondary Mathematics Teachers’ Knowledge Of Statistics And Probability Via Professional Development, Lina Devaul

UNLV Theses, Dissertations, Professional Papers, and Capstones

A professional development program (PSPD) was implemented to improve in-service secondary mathematics teachers’ content knowledge, pedagogical knowledge, and self-efficacy in teaching secondary school statistics and probability. Participants generated a teaching resource website at the conclusion of the PSPD program. Participants’ content knowledge change and self-efficacy change were measured. After PSPD, three participants were selected to represent three types of change. Teachers’ classroom instructions were video-taped and analyzed to explore the enactment of PSPD components, such as activities and concepts. Interviews were conducted to assess factors that facilitated teachers’ change and the enactment of PSPD components. Preservice teachers who majored in …


Stem High School Teachers’ Views Of Implementing Pbl: An Investigation Using Anecdote Circles, Aimée L. Dechambeau, Susan E. Ramlo Feb 2017

Stem High School Teachers’ Views Of Implementing Pbl: An Investigation Using Anecdote Circles, Aimée L. Dechambeau, Susan E. Ramlo

Interdisciplinary Journal of Problem-Based Learning

Problem-based learning (PBL) has been gaining in popularity, especially within the context of STEM-based (science, technology, engineering, and mathematics) schools. Program assessments for these schools typically focus on student standardized test scores rather than the needs of the teachers. This study utilized anecdote circles, storytelling via moderated group discussions, to investigate teachers’ needs related to developing and implementing authentic, interdisciplinary PBL activities in an urban, public STEM high school. Teacher experiences and viewpoints were explored within three broad themes: assessment; coaching and training; and authentic learning. The analyses provide insights for transitioning a school for effective PBL implementation as well …


Teacher Challenges In Implementing Cognitively Demanding Tasks In The Mathematics And Science Classrooms, Angelica Monarrez Monarrez Jan 2017

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 …
