This dissertation uses a three-manuscript style, and the ultimate purpose was to support critical thinking teaching in K-12 education from a systematic view concerning the lack of critical thinking in the young generation. The three manuscripts included in this dissertation were entirely or partly adapted based on three published or submitted research papers. The first research paper is a literature review article with an introduction to a development framework of nine principles, which provided a new view to developing critical thinking in younger children based on conceptual understanding of critical thinking. The second research paper is a study I coauthored with J. Michael Spector, which calls for more attention to the development of human intelligence given the rapid development of artificial intelligence and proposed that developing inquiry and critical thinking is a key to develop human intelligence. The third research paper reports an investigation over middle school educators' conceptualization of critical thinking and its alignment with the established theory and research. The major purpose was to connect the established theory and research with educational practices regarding what critical thinking constitutes. The significance of this study is to reveal the issues behind the abstract understanding of critical thinking and address the …

The purpose of this convergent mixed method study was to determine whether or not there is a difference in the perceived and actual financial literacy scores of millennials. Exploring the following research questions and hypotheses helped to expand knowledge around actual financial literacy and several other characteristics, including perceived financial literacy, especially among millennials (individuals born between 1981 and 1996): RQ1: What is the difference between millennials' actual and perceived financial literacy scores? RQ2: To what extent do socioeconomic status, gender, and having a bank account predict millennials' financial literacy scores? H0: There is no relationship between millennials' socioeconomic status, gender, banking status and their financial literacy scores. RQ3: What video delivery methods (if any) are millennials using to gain financial literacy knowledge in informal learning environments? Millennial participants (N = 207) were asked to complete a survey. Participants' perceived financial literacy scores were higher than their actual financial literacy scores. While males had higher perceived financial literacy ratings, females accounted for the majority of participants who scored four or above on a 5-point scale for actual financial literacy. Although, the null hypothesis was incorrect, the independent variables used in the ANOVA tables accounted for less than 15% of financial …

The objective of this study was to locate and describe the learning affordances used within research studies on instructional design. Allowing an instructional designer to see what was used and how applicable it might be for future design would assist with better course creation. Current and past literature supported the importance of this concept after examination of how course creation has evolved within the field of instructional design. Further, the findings elucidated how to help the field evolve in the future by expanding knowledge about learning affordances and providing the broadest set of conceptual definitions by the academics working in the field to include them in their research and instructional designs.
