A Statistically Significant Determination From Pretest To Posttest In Knowledge Of Electrophoresis Concepts, Parker Megehee Nelson
A Statistically Significant Determination From Pretest To Posttest In Knowledge Of Electrophoresis Concepts, Parker Megehee Nelson
Dissertations
The statistical significance from pretest to posttest of 109 high students constructing an electrophoresis chamber or not was explored. The students tested were from six intact biology classrooms. Three classes were treatment groups and three were control groups. The three biology teachers each taught a control and treatment group classroom. Except for building the electrophoresis chamber, students in both groups received identical instruction and testing. Pre- and posttest data was examined by means of a content valid test constructed by the researcher and biology teachers. In order to examine the statistical significance from pretest to posttest in knowledge of electrophoresis …
Inquiry, Efficacy, And Science Education, Heather Christa Scott
Inquiry, Efficacy, And Science Education, Heather Christa Scott
Electronic Theses and Dissertations
Developing learners who are equipped to think critically about the vast information circulating around them is essential in their preparation for a role in society today. The use of effective inquiry-based instruction is not a widespread practice among K-12 classrooms. Many secondary and post-secondary science instructors see the valuable link between students asking questions and the development of critical thinking. Inquiry-based instruction provides student opportunities to ask questions, design methods of investigation, gather information, and finally reach conclusions based on evidence. However, this instruction style is rarely used in the classroom, particularly in elementary classrooms. This study examines the relationships …
Obstacles To Developing Digital Literacy On The Internet In Middle School Science Instruction, Jamie Colwell, Sarah Hunt-Barron, David Reinking
Obstacles To Developing Digital Literacy On The Internet In Middle School Science Instruction, Jamie Colwell, Sarah Hunt-Barron, David Reinking
Teaching & Learning Faculty Publications
Obstacles, and instructional responses to them, that emerged in two middle school science classes during a formative experiment investigating Internet Reciprocal Teaching (IRT), an instructional intervention aimed at increasing digital literacy on the Internet, are reported in this manuscript. Analysis of qualitative data revealed that IRT enabled students to explain and demonstrate appropriate strategies for locating and evaluating information on the Internet when they were asked to do so. However, students did not use these strategies or they quickly abandoned them when working independently or in small groups during inquiry projects. Data revealed three obstacles that inhibited efforts to promote …
Re-Imagining Specialized Stem Academies: Igniting And Nurturing ‘Decidedly Different Minds,’ By Design, Stephanie Pace Marshall
Re-Imagining Specialized Stem Academies: Igniting And Nurturing ‘Decidedly Different Minds,’ By Design, Stephanie Pace Marshall
Stephanie Pace Marshall, Ph.D.
This article offers a personal vision and conceptual design for reimagining specialized science, technology, engineering, and mathematics (STEM) academies designed to nurture decidedly different STEM minds and ignite a new generation of global STEM talent, innovation, and entrepreneurial leadership. This design enables students to engage actively in the authentic work, modes of inquiry, and practices that distinguish four STEM learning cultures, environments, and communities: (a) Inquiry and Research Laboratory and Interdisciplinary Learning Center—develops disciplinary, interdisciplinary, and inquiry-based thinking; (b) Innovation Incubator and Design Studio—ignites innovative and design-based thinking; (c) Global Leadership and Social Entrepreneurship Institute—nurtures change leadership and systems-based thinking; …
Developing Pedagogical Content Knowledge Of Science Teachers Through Action Research: A Case Study From Pakistan, Nelofer Halai, Manzoor Ali Khan
Developing Pedagogical Content Knowledge Of Science Teachers Through Action Research: A Case Study From Pakistan, Nelofer Halai, Manzoor Ali Khan
Institute for Educational Development, Karachi
The aim of this study is to analyze the action research undertaken by Khan as a teacher researcher in a private school as part of the degree requirement of his M.Ed. program in Teacher Education at the Aga Khan University, Institute for Educational Development. The purpose of this analysis undertaken by the first author and supervisor of the study in collaboration with Khan was to understand the development of Pedagogical Content Knowledge (PCK) of the teacher researcher through action research in a science classroom in the context of Pakistan. Khan taught the concepts of heat and temperature using an inquiry …

Inquiry Based Mathematics Instruction Versus Traditional Mathematics Instruction: The Effect On Student Understanding And Comprehension In An Eighth Grade Pre-Algebra Classroom, Kyle Ferguson
Master of Education Research Theses
This quantitative study provides information obtained through the use of inquiry-based mathematics instruction verses traditional mathematics instruction. The use of each curriculum was implemented into two classrooms of eighth grade pre-algebra students. The study was based on data collected before and after each of the two units of study. Fifty-two suburban eighth grade students represented the sample population. Results of the SPSS analysis showed that both classes made improvement from their pre-test to their post-test for both units but students receiving instruction through inquiry-based instruction showed significantly more improvement on the second unit. These results can be useful for educators …
