An Analysis Of Secondary Integrated Stem Lesson Plans: Common Characteristics, Learning Expectations And The Impact From The Teacher's Definition Of I-Stem, Jacob Hayward

Graduate Theses and Dissertations

This qualitative study investigated teachers’ understanding of their definition of I-STEM (Integrated STEM education), how those understandings manifested into lessons and associated lesson artifacts, how they assessed students in such lessons, and what factors or rationales supported their ability to conduct or not conduct I-STEM lessons. A survey was sent to the members of four professional organizations representing I-STEM disciplines to solicit their participation in this project. Ten teachers ranging from grades 9-12 participated in this study. Of those who responded, six teachers identified with National Science Teachers Association (NSTA), three teachers selected International Technology and Engineering Education Association (ITEEA), …

Comparing Game Simulation To Concept Models For Student-Centered Learning In Biology, Margaurete Romero

USF Tampa Graduate Theses and Dissertations

Science education research continues to demonstrate improved learning with active-learning techniques compared to lectures. However, the question of which active-learning methods are the most effective for learning complex scientific principles in various context still remains. Models are commonly used in activities that allow students to simplify complex systems and understand how components interact. I investigated the outcomes for student learning and engagement of two model-based activities - concept models and game simulations. The activities were conducted in an introductory biology course in sixteen discussion sections. Eight sections were assigned to the concept model activity and eight to the simulation activity. …

Activating Teachers’ Creativity And Moral Purpose In Science Education, Martin Westwell, Sonia Cooke

2009 - 2019 ACER Research Conferences

Over the last three years, the Scientist in Residence program (a collaboration between the Department of Education and Child Development, and Flinders University) investigated a model of professional learning in science education that capitalised upon teachers’ moral purpose and drove their creativity. Insight into how teachers transformed their science classrooms is provided through examples of activities, work samples and clips of teachers describing how they changed their practice and how that, in turn, changed the engagement and achievement of the children. These resources will serve to illustrate some of the principles of practice that the teachers drew upon. In particular, …

Project-Based Science Instruction For General-Education Undergraduates And Seventh Graders: Practices, Proficiency, And Pitfalls, Walter S. Borowski, Malcolm P. Frisbie

EKU Faculty and Staff Scholarship

For three semesters we conducted a general-education course designed for both undergraduates and seventh-graders in which students investigated contaminant sources and water quality of a local stream. The middle school students attend a local, county school that draws its students from disadvantaged areas of the town of Richmond, Kentucky. Undergraduates were general-education honors students with little predilection toward science. The instructors guided undergraduates through the project, and our honors students then mentored the middle-schoolers in their scientific endeavors.

Both sets of students serially investigated the chemical and biological properties of a typical upland stream (Tates Creek, Madison County, Kentucky) impacted …

Exploring Science Teachers’ Self-Efficacy Perceptions To Teach In Ontario’S Diverse Classrooms: A Mixed-Methods Investigation, Mithila Vidwans

Electronic Thesis and Dissertation Repository

In the past few years, Canadian schools have experienced increasing diversity with a large number of English Language Learners (ELLs) becoming part of the mainstream classroom. Research has shown that ELLs will achieve academic success when their backgrounds are incorporated within the curriculum and pedagogy (Gay, 2000). However, our curriculum is largely Eurocentric and caters predominantly to mainstream students. As a result, it has become critical to investigate teachers’ perceptions in terms of providing inclusive pedagogy in various classroom contexts. Hence, the purpose of this study was to examine the self-efficacy perceptions of Ontario’s Science teachers to teach in diverse …

Understanding College Students’ Exam Process In A General Chemistry Course, Angela Willson

Masters Theses

The main way most college chemistry courses assess what a student has learned is through a summative exam. After introductory science courses, such as general chemistry, many students cite poor teaching and disappointing grades in these courses as a reason for dropping out of STEM programs. There has been a lack of qualitative research on students’ experiences of the complete process of taking an exam from start to finish, or the exam process, which includes preparing for an exam, taking an exam, receiving feedback, and responding to feedback after the exam has been graded.

My goal in this exploratory study …

Guided Educational Tourism As Informal Science Education: An Empirical Study, Joseph Martin Lane

Dissertations

The scientific research and education communities have long had the goal of advancing the publics’ understanding of science. Informal science education is a powerful mechanism for shaping human conduct, enhancing quality of life, and advancing the publics’ understandings and values regarding science. Guided educational tours (that present science content) provide visitors with unique opportunities to observe and discuss scientific phenomena in the field. Available empirical research related to learning science from guided educational tours is, at best, limited. Research leading to the development of effective guided educational tours that present and interpret scientific information is of interest to both non-profit …

Using Mobile Technology To Engage Middle School Students In The Scientific Practice Of Argumentation Via Screencasting, Patricia Anne Mcginnis

Boise State University Theses and Dissertations

This case study examined the use of mobile devices in supporting data collection and argumentation in the sixth grade science classroom. Mobile devices were used for data collection during laboratory activities and for constructing screencasts of science arguments. Findings revealed that students exhibit little planning when collecting digital data. Students used the digital data to add visual interest to their screencasts, support observations, and support inferences. Students who used the screencasting application’s narration and annotating tools were more likely to create appropriate and sufficient science arguments than their peers. One of the low achieving students in this study was able …

Expecting Success: Factors Influencing Ninth Graders' Science Self-Efficacy, Elizabeth Donahue

Dissertations, Theses, and Capstone Projects

What factors influence ninth grade students’ expectations for success in science? Using social cognitive theory and bioecological systems theory as theoretical frameworks, this dissertation employs data from the High School Longitudinal Study of 2009 (HSLS:09) to examine the relative impact of teacher practices and their perceived attitudes on students’ science self-efficacy. Further, as they relate to this broader issue, the relative impact of student subjective task value and teacher characteristics is also investigated.

It has been well documented that U.S. students are not achieving at satisfactory levels in science. Education policy has focused on improving science teacher quality as one …

Parts Of The Whole: Teaching Quantitative Reasoning In The Predator-Prey Model, Dorothy Wallace

Numeracy

The classical predator-prey equations are in nearly every differential equations text and mathematical biology text. Usually they are presented fait accompli, leaving the student to analyze them or play with a computer program. Here we show that the process of fully understanding where these equations come from and how they are derived provides numerous opportunities to teach or reinforce quantitative reasoning skills necessary to future scientists. This example is used to invoke logic, systems thinking, causal reasoning, understanding functions of one or more variables, quantities versus rates of change, proportional reasoning, unit analysis, and comparison to data.

Use Of Dynamic Visualizations For Engineering Technology, Industrial Technology, And Science Education Students: Implications On Ability To Correctly Create A Sectional View Sketch, Petros J. Katsioloudis, Daniel Dickerson, Vukica Jovanovic, Mildred V. Jones

Engineering Technology Faculty Publications

Spatial abilities, specifically visualization, play a significant role in the achievement in a wide array of professions including, but not limited to, engineering, technical, mathematical, and scientific professions. However, there is little correlation between the advantages of spatial ability as measured through the creation of a sectional-view sketch between engineering technology, industrial technology, and science education students. A causal-comparative study was selected as a means to perform the comparative analysis of spatial visualization ability. This study was done to determine the existence of statistically significant difference between engineering technology, industrial technology, and science education students’ ability to correctly create a …
