Dynamic Variables Of Science Classroom Discourse In Relation To Teachers’ Instructional Beliefs, Sibel Kaya

Australian Journal of Teacher Education

The current study examines if the occurence of dynamic variables namely, authentic questions, uptake, high-level evaluation and student questions in primary science classrooms vary by teachers’ instructional beliefs. Twelve 4^th grade teachers from two different schools volunteered to participate in the study. Data was collected through semi-structured interviews and classroom observations. Both qualitative and quantitative methods were used to determine teachers’ instructional beliefs, classroom practices and dynamic variables of classroom discourse. Results showed that teachers were more teacher-centred in their classroom practices than their instructional beliefs. There were no differences among teachers with different instructional beliefs in terms ...

Why Do Undergraduate Women Persist As Stem Majors? A Study At Twotechnological Universities, Ronald Brandt

Seton Hall University Dissertations and Theses (ETDs)

Women continue to be underrepresented in STEM fields despite significant policy efforts to increase the number of qualified women. Prior research focused on access for women into advanced high school mathematics and science courses. Parity has been achieved in academic prerequisites for STEM studies in higher education, yet the number of women majoring in STEM has remained static. Recent research has focused on the socio-cultural obstacles that women face, including a lower self-confidence in their abilities, bias and gender stereotypes.

A survey was undertaken to examine the self-confidence, opinions and backgrounds of female students persisting as STEM majors at two ...

Exploring The Factors That Influence And Motivate Female Students To Enroll And Persist In Collegiate Stem Degree Programs: A Mixed Methods Study, Rosemary L. Edzie

Educational Administration: Theses, Dissertations, and Student Research

Nationally, the need for an increase in interest, enrollment, and degrees awarded from science, technology, engineering and mathematics (STEM) degree programs continues to suffer. While students are enrolling in collegiate STEM degree programs, it is not occurring at a rate that meets the workforce demand. In addition to the concern that there is not a sufficient amount of collegiate STEM majors, there is a concern over too few females enrolling and persisting in collegiate STEM degree programs.

This mixed methods sequential exploratory research study considered the factors that influence and motivate undergraduate female students to enroll and persist in collegiate ...

Elementary School Teachers' Interpretation And Promotion Of Creativity In The Learning Of Mathematics: A Grounded Theory Study, Yinjing Shen

Open Access Theses and Dissertations from the College of Education and Human Sciences

Creativity is important for young children learning mathematics. Comparing the investment theory of creativity and national standards and principles for early mathematics shows that doing mathematics is more than applying rules and procedures; rather, learning mathematics takes a lot of creativity. However, much literature claimed that creativity for young children in the learning of mathematics was not adequately supported by teachers in the classroom due to teachers’ poor college preparation in mathematics content knowledge, teachers’ negativity towards creative students, teachers’ occupational pressure, low quality curriculum, and the like. The purpose of this grounded theory study was to generate a model ...

The Maritime Climate Of The Chesapeake Bay Area: Analysis And Application In The Middle School Classroom, Carrie A. Dunham, Katlin M. Major, Kelsey N. Scheitlin

American Journal of Undergraduate Research

Maritime climates experience moderate temperatures due to the specific heat of the nearby water. The first objective of this study is to analyze the relationship between temperature (maximum, minimum, and range) and proximity to the Chesapeake Bay and Atlantic Ocean. Results show that the annual Tmin (Tmax) means are smaller (greater) at the most continental locations, while the maritime locations experience cooler days and warmer nights. This results in a smaller DTR in maritime locations. The most notable seasonal differences in the variables occur during the transitional seasons of spring and fall when the lag time of the water temperature ...

Comparing Technology-Supported Teacher Education Curricular Models For Enhancing Statistical Content Knowledge, Dionne Cross Francis, Rick Hudson, Crystal Vesperman, Arnulfo Perez

Interdisciplinary Journal of Problem-based Learning

Recent calls have been made to enhance and extend the statistical experiences of K-12 students. However, to ensure that such goals are met, teachers also need to develop deep conceptual understanding and pedagogical content knowledge that are essential to statistical thinking and reasoning. In this regard, over the past two decades, leading thinkers and professional organizations had advocated that teaching and curricula should be focused and organized around problem solving. In this paper we describe three such technology-supported curricula—a project-based learning (PjBL) unit, problem-solving activities (PS) unit, and a model-eliciting activities (MEA) unit—that align with this perspective and ...

Epics: Broadening The Pathway Into Stem, Mindy Hart, Patrice M. Buzzanell, William Charles Oakes, Carla B Zoltowski

ADVANCE-Purdue Gender and STEM Research Symposium

The Engineering Projects in Community Service (EPICS) program was co-founded at Purdue University in 1995 and has since spread throughout the United States and globally with inroads into K-12 education through EPICS High. This presentation offers a synthesis of research findings and interventions gleaned from several datasets about students’ and alumni’s reported experiences with EPICS and the consequences of their participation. In particular, this presentation discusses the ways in which EPICS provides a different vantage point on the underrepresentation of women in STEM (science, technology, engineering, and math). Specifically, researchers have been tackling this issue of underrepresentation for decades ...

Engaging Non-Scientists In Stem Through Problem-Based Learning And Service Learning, Andrew Tawfik, Rebecca J. Trueman, Matthew M. Lorz

Interdisciplinary Journal of Problem-based Learning

This study follows the evolution of a single biology course designed for non-science majors. In its original design, the course used only traditional pedagogical techniques, such as lecture and textbook homework assignments. Over several iterations of the course, the class combined problem-based learning (PBL) and service learning to better support student knowledge. For this study, our goal was for students to learn biology concepts as they engaged in a lake cleanup project within the greater Chicago metropolitan area. Data sources consisted of pretest, posttest, and final exam scores to assess learning. The results suggest the combination of PBL and service ...
