Measuring Social Studies Teacher Self-Efficacy: Development Of A Valid, Reliable, And Fair Social Studies Self-Efficacy Scale, Leona Calkins

UNLV Theses, Dissertations, Professional Papers, and Capstones

Social studies education provides unique opportunities for students to learn about the democratic process and, more importantly, how to engage in civic life to become active citizens. It is through meaningful social studies education that students are deliberately helped to understand the world, and are provided space to discuss, deliberate, and inquire about problems in the world, both past and present, and then learn how they can work to solve these problems (NCSS, 2013a; Parker, 2008). Considering the role of social studies education in helping develop active citizens, there has been a call for social studies teachers to provide instruction …

How Do Beliefs Come Into Play? An Examination Of The Influence Of Core Conceptions On Science Teachers’ Inquiry Lesson Plan Designs, Mehmet Fatih Dulger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Teaching science through inquiry-based methodologies has been advocated by several governmental and professional organizations (National Research Council [NRC], 2000; NGSS Lead States, 2013); however, their use is not widespread. Why is this? What science teachers do in their classrooms is shaped by their beliefs, especially their beliefs about the nature of science, about the goals and purposes of school science and the goals of teaching science, and about the teaching and learning science. By critically examining these core conceptions and their influence on teacher lesson planning, this study aims to shed light on the role conceptions play when teachers design …

Understanding And Addressing Preservice Elementary Teachers’ Misconceptions In Science Education, Nicole Juliana Thomas

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prior research has demonstrated that both children and adults alike hold misconceptions about various scientific phenomena (Snyder & Sullivan, 1995; Driver et al., 1985). These misconceptions range from a variety of different fields, including astronomy and space science, environmental biology, and geology, among others (Miller & Brewer, 2010; Wandersee et al., 1994; Ritger & Cummins, 1991). Research suggests that the vast majority of misconceptions are formed early in a students’ educational career, and these misconceptions could be held throughout adulthood unless they are sufficiently addressed (Coley & Tanner, 2012; Posner et al., 1982; Nehm & Reilly, 2007; Sadler et al., …

The Relationship Between Teaching Approaches And Student Science Achievement For Four Racial Groups In Us Eighth Grade Classes, Su Gao

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lower science achievement and substantial racial performance gaps persist among students in the US. In the current reform of science teaching, inquiry-based science teaching is assumed effective in improving all student science learning in both scientific content and process and reducing learning gaps across racial groups. Conversely, traditional didactic science teaching is believed to be the most popular and has contributed to lower science achievement and the racial gap. These two assumptions, although central to science teaching reforms, cannot be empirically sustained in the existing literature on science teaching. Framed through the theoretical perspectives of inquiry-based instruction and culturally relevant …

Kindergarteners' Concept Development In Science And Literacy Learning Through Concept-Oriented Reading Instruction (Cori), Char Adelia Moffit

UNLV Theses, Dissertations, Professional Papers, and Capstones

The notion that "real work" is somehow different from authentic and engaging discovery is troublesome. (Passman, 2001, p.196)

This qualitative case study examined science concept and literacy learning along with engagement of the students in a Kindergarten class in which science and literacy instruction was integrated through Concept-Oriented Reading Instruction (CORI). CORI is an instructional framework created to increase reading engagement by teaching reading comprehension strategies along with science concepts (Guthrie, et al., 1996). This study explored CORI at the Kindergarten level to examine how this curriculum framework engaged young learners in science concept and literacy learning. The study was …

Assessing The Effect Of Simulation Models On Systems Learning In An Introductory Environmental Science Course, Heather J. Skaza

UNLV Theses, Dissertations, Professional Papers, and Capstones

While there is plenty of anecdotal evidence within the systems dynamics community supporting the use of systems simulations in the classroom to improve student understanding, there is little published, controlled, experimental research. This paper describes the results of a paired experiment testing the effect of using system dynamics simulations to increase systems understanding in an introductory environmental science course. We believed that the students using the systems simulations would demonstrate a greater systemic understanding of environmental issues than those who did not.

We conducted an experiment during the fall semester of 2009, with 304 students enrolled in four sections of …
