Integrating Science And Literacy For Young English Learners : A Pilot Study., Yuliya Ardasheva, Lori A. Norton-Meier, Thomas R. Tretter, Sherri L. Brown

Thomas Tretter

This pilot investigated the promise of positive outcomes in literacy, science, and social behavior on K– 2 English learner (﴾EL)﴿ students after two months of implementation of the Science Inquiry Centered Argumentation Model (﴾ScICAM)﴿—a systematic teaching approach to science learning that integrates literacy instruction and argument-‐based inquiry. The sample included 17 teachers and 31 EL students. Results indicated that teacher practices (﴾proximal outcomes)﴿ aligned well with the ScICAM approach and resulted in increases in EL student learning (﴾distal outcomes)﴿. Teacher increase in the use of inquiry and writing scaffolds and student growth in the ability to express understandings through oral …

Undergraduate Teaching Assistant Impact On Student Academic Achievement., Stephanie B. Philipp, Thomas R. Tretter, Christine V. Rich

Thomas Tretter

This study evaluated the impact that trained and supported undergraduate teaching assistants (UTAs) may have had on the academic achievement of students in the first semester of an introductory chemistry course for science and engineering majors. Framed by the concepts of Lave and Wenger’s Community of Practice and Wheeler, Martin and Suls’ Proxy Model of Social Comparison , the study used an untreated control group with dependent post-test only design. Covariates related to student academic achievement and contextual variables were also collected and used to build models for the final exam core outcome variable. Hierarchical linear models indicated that having …

Development Of Undergraduate Teaching Assistants As Effective Instructors In Stem Courses., Stephanie B. Philipp, Thomas R. Tretter, Christine V. Rich

Thomas Tretter

This study examined the development of peer mentoring skills and deepening of content knowledge by trained and supported undergraduate teaching assistants (UTAs) working with students in entry-level STEM courses across nine departments at a large research intensive U.S. university. Data were collected from two sources: a survey with 10 items requesting 5-point Likert-type responses and an open-ended reflection written by each UTA to process their experiences. The survey responses were analyzed by comparing rates of agreement across the 10 items. Statements from the reflections were categorized by research question and descriptively labeled to capture the essence of implied or explicit …
