Conditions Supporting The Development Of Scientific Argumentation In High School Chemistry Classrooms: The Role Of Question Prompts And An Interactive Simulation, Tugba Keser

Doctoral Dissertations

The purpose of this case study was to provide benefit to preservice and inservice science teachers, who have an interest in applying scientific argumentation in their high school chemistry instructions, by investigating role of question prompts and an interactive simulation supporting the development of scientific argumentation. In particular, the study examined the quality of students’ arguments changing over time in scientific argumentation when they constructed and defended their arguments using the “Gas Properties” computer simulation. For this purpose, forty-seven11^th grade students from four classes first worked in pairs and then, all the pairs returned the classroom for discussion. One …

Undergraduate Women In The Stem Fields And The Use Of Academic Library Resources And Services, Rebecca O'Kelly Davis

Doctoral Dissertations

Women majoring in the Science, Technology, Engineering and Mathematics (STEM) fields are few in number. This research will be conducted in an effort to understand the use of academic library resources and services by undergraduate women in the STEM fields. Data collection methods consisted of three focus groups and five interviews with undergraduate women in the STEM fields, and three focus groups and two interviews with academic librarians and library staff familiar with library resources and services in each of the STEM fields conducted at a Research I University in the USA. Grounded theory principles provided a basis for the …

Development Of The Setis Instrument To Measure Teachers' Self-Efficacy To Teach Science In An Integrated Stem Framework, Monica Clutch Mobley

Doctoral Dissertations

Integrated STEM teaching and learning has gained increased attention in recent years as schools try to prepare students for 21^st century careers. Goals of integrated STEM teaching are in alignment with goals of science education reform efforts as evident in recent document such as the Next Generation Science Standards (Achieve, Inc., 2013) and efforts are underway to encourage science instruction from within an integrated STEM framework. Teaching science content in an integrated STEM context is a complex act placing great cognitive and emotional demands on teachers, many of whom lack experience with this manner of teaching and may also …

The Effects Of A Varied Method Of Instruction On Student Achievement, Transfer, Situational Interest, And Course Retention Rates In Community College Developmental Mathematics, Kevin L. Mccandless

Doctoral Dissertations

The purpose of this quasi-experimental study was to compare the effects of a varied method of instruction on student achievement, knowledge transfer, situational interest, and course retention rates, relative to a non-varied method of instruction, in community college developmental mathematics. The varied method of instruction consisted of active learning teaching practices with foundations in social constructivism, whereas the non-varied method of instruction was founded in Cognitive Load Theory and consisted primarily of explicit instruction and individual practice.

An initial sample of 139 students who enrolled in six sections of Beginning Algebra at an urban community college in Northern California participated …
