The Technological Immersion Learning Theory (TILT) was developed through a classic grounded theory study in the seminal tradition of Glaser and Strauss (1967) and Glaser (1978, 1992, 1998, 2001, 2007). The purpose of the study was to investigate an exemplary case of self-determined technology enthusiasts in the hopes of generating a substantive grounded theory that conceptualizes their experiences and concerns. Twelve unstructured interviews of amateur radio enthusiasts from the eastern United States provided the initial / primary data for this study. Experimenting and self-teaching in technological activities was highlighted as the main concern of the participants. The basic social process (BSP) of technological immersion learning (TIL) emerged as a theoretical construct and core variable that illuminates the experiences of individuals immersed in a community of practice, where hands-on engagement with technology is a primary activity. Adventuring, Affirmation, Doing Technology, Experimenting, Overcoming Challenge, Self-teaching, and Social Networking were properties of technological immersion learning that interact dialectically in an amplifying causal loop, with Problem solving and Designing as active sub processes in response to unmet challenges. TIL occurs cyclically in three stages, beginning with Induction, a credentialing stage wherein the neophyte is prepared with the necessary knowledge and skill to become a novice participant in an activity. The transition from Induction into the Immersion phase is a status passage whereby the novice is absorbed into the technical culture of the group and commences autonomous active participation in hands-on experimenting. Hands-on experiences with experimenting, problem solving and social interactions provide diverse learning and affirmation for the doer and multiple sources of feedback that promote sustained engagement. The transition into the Maturation phase proceeds gradually over time, with prolonged engagement and cumulative gains in knowledge, skill, and experience. Maturation is a quasi-stable state that remains responsive to new contexts as a random-walk process, wherein trigger events can initiate new cycles of technological immersion learning in a perpetually evolving process of personal development. Engagement, Empowerment, and Self-Actualization are underlying dimensions of the TIL basic social process that provide the impetus for continued persistence and personal development. / Ph. D.

Experiential opportunities at the secondary level give students the 'intimate and necessary relation between the processes of actual experience and education' (Dewey, 1938, p. 19-20). Career and Technical Education classes (CTE) and co-curricular experiences, one type of experiential learning, underpin and cultivate student curiosity and often channel interests into STEM-related post-secondary disciplines and career choices. There is little existent research on the characteristics of exemplary experiential learning opportunities and the impact on stakeholders. This study is intended to identify the qualities and characteristics of an exemplary secondary experience through the lived experiences of the stakeholders; students, STEM-related teachers, and CTE/STEM Administrators. A qualitative research design was used to examine characteristics and implications for students of four STEM-related programs throughout Virginia. Conclusions from the study include fundamental principles for providing exemplary experiential STEM-related learning opportunities. These principles include: providing hands-on, real world learning opportunities for students, providing learning opportunities that will enhance student ownership in their learning, providing unique and comprehensive career exploration opportunities for students, providing a schedule for teachers that will give them time to plan, deliver, and manage exemplary experiential learning opportunities, providing continual teacher and administrator in-service training relative to planning and implementing exemplary experiential learning opportunities, investing appropriate funds for providing exemplary experiential learning opportunities. Establishing and maintaining active partnerships with business/industry and colleges/universities, and maintaining active advisory communities, providing appropriate staff to support the provision of exemplary experiential learning opportunities is needed. The need for adequate funding, improving perception of CTE and STEM programs, and small class sizes was also recommended. / Ph. D.

Increasing underrepresented minority youth (URMY) engagement in STEM education remains at the forefront of our Nation's educational battle. The aim of this study was to create, implement, and evaluate the impact of innovative food science and technology (FST) lesson plans on URMY engagement in, and attitudes towards science, and their awareness of the field of FST. The 2011 United States census recalls that URMY make up only 13.3% of the STEM workforce. This study identifies URMY as individuals representing one or more of the following demographics: Low income, African American, Latino(a) American, and Indian American. Eight 5th-6th grade youth participated in a seven-week program, The Enliven Program (TEP), which is a STEM education program created for the purpose of this. The Enliven Program focuses on youth engagement in science learning through the implementation of a FST curriculum. The lessons delivered in TEP utilized the Biological Sciences Curriculum Study (BSCS) 5E instructional model as its foundation. This model focuses on five phases of student centered learning: engagement, exploration, explanation, elaboration, and evaluation. Data was collected using a fixed-mixed methods design. A qual-quan approach was employed to measure youths' positive behavioral and cognitive engagement in science learning. Measures of positive behavioral and cognitive engagement demonstrated that youth were positively behaviorally and cognitively engaged in the science learning activities. Furthermore, relationship building played an instrumental role in maintaining youth participants' positive attitudes towards and engagement in TEP activities. The results display an overall increase in youth's desire to do science and self-concept in science. / Master of Science in Life Sciences

With the recent release of the Next Generation Science Standards (NGSS) (NGSS Lead States, 2014b) science educators were expected to teach engineering content and practices within their curricula. However, technology and engineering (T&E) educators have been expected to teach content and practices from engineering and other disciplines since the release of the Standards for Technological Literacy (ITEA/ITEEA, 2000/2002/2007). Requisite to the preparation of globally competitive STEM literate individuals is the intentional, concurrent teaching of science, technology, and engineering concepts. Many studies have examined the pedagogical content knowledge (PCK) (Shulman, 1987) of science and T&E educators, but none have examined the science PCK of T&E educators. The purpose of this study was to examine the extent of the relationship between T&E educator’s science and T&E preparation experiences, and their teaching of science content and practices. This study, which employed a fully integrated mixed methods design (Teddlie & Tashakkori, 2006), was conducted to inform the pre- and in-service preparation needs for T&E educators. A random sample of 55 Foundations of Technology (FoT) teachers across 12 school systems within one state participated in an online survey, leading to eight teachers being purposefully selected for classroom observations. Data collected from the surveys and classroom observations were analyzed through Spearman’s rho tests to examine relationships between preparation factors and teaching of science content and practices. These data were corroborated with curriculum content analyses, classroom observations, and interview responses to validate the results. Analyses of the data across all three methods revealed significant correlations between many preparation factors and the teaching of science content and practices. Specifically the amount of high school and undergraduate physics courses, and T&E and science in-service delivered were found to have statistically significant, strong positive correlations. These findings suggest T&E educators with increased amounts of these preparation experiences can be expected to teach science content and practices more proficiently. The findings and conclusions drawn from the data analyses provide implications for science and T&E educators, researchers, preservice programs, and in-service professional development efforts. The discussion and implications suggest the need to conduct replication studies in different contexts. / Ph. D.

In response to STEM (science, technology, engineering, mathematics) educational reform, pedagogical approaches such as technological/engineering design-based learning (T/E DBL) have received increased emphasis as a means to enrich student learning and develop their higher-order cognitive competencies. Despite students exposure to the T and E of STEM as a means to make connections and improve learning (NAE and NRC, 2009), there still exists minimal evidence such experiences have a positive impact on their cognition and achievement (Honey, Pearson, and Schweingruber, 2014). Additionally, although research has well illustrated the design cognition of professional designers, and even students at the collegiate level, few investigations of high school students' cognitive activity during designing has been undertaken (Crismond and Adams, 2012; Hynes, 2012; Lammi and Becker, 2013). Furthermore, as researchers have begun to address this gap, broad coding schemes have been employed, describing students' cognitive efforts in terms of comprehensive categories such as formulation, analysis, and synthesis. However, as previous research has demonstrated nuances among existing categories (Purcell, Gero, Edwards, and McNeill, 1996), what has yet to be done is describe K-12 students' cognitive behaviors in terms of these underlying mechanisms. The purpose of this study was to characterize students' cognitive processes during engineering design at a more distinct level, which can increase understanding and begin to address the minimal attempts to 'connect research findings on how people design with what teachers need to understand and do to help K-16 students improve their design capability and learn through design activities" (Crismond and Adams, 2012, p. 738). The methodology of this study was informed by procedures of cognitive science and verbal protocol analysis. The primary form of data analyzed was audio and video recordings of the design task. The recorded data, in transcript form, was coded using the Purcell, Gero, Edwards, and McNeill (1996) framework. These coded data were then analyzed using descriptive and inferential statistics. Findings from this study revealed that significant differences existed between high school seniors who took pre-engineering courses, and those who did not when engaged in Consulting Information about the Problem (Cp) and in considering System issues, which examined the problem from the point of view of the user. Additionally, Proposing a Solution (Ps), Postponing a Design Action (Pd), and Looking Back (Lb) approached a value of statistical significance in differences between the groups of participants. Findings also characterized how students exert the most and least amount of their cognitive effort in relation to the Problem Domain: Degree of Abstraction and Strategy Classification coding schemes. / Ph.

This study identified key instructional practices for science, technology, engineering, and mathematics (STEM) lessons for students with disabilities (SWD) based on the perceptions of teachers. Barriers to STEM lessons for SWD were identified, as well as the professional development desired by teachers. SWD can benefit from participation in STEM lessons. STEM is an acronym that is often defined as an interdisciplinary approach to learning by incorporating at least two of the disciplines with real-world applications through problem-solving projects. STEM lessons can offer opportunities for K–12 students to engage in 21st-century skills and the 5 C's (citizenship, collaboration, communication, creativity, and critical thinking), which are skills that are desired for college and career readiness and for competition in a global economy. This basic qualitative study consisted of 13 interviews (5 elementary, 4 middle, and 4 high school) with teachers from 12 schools. Results were analyzed using deductive coding to identify instructional practices, barriers, and recommended professional development. Findings suggest that knowledge of the SWD, building relationships, use of support staff and others, intentional grouping, assigned group roles, hands-on learning, and classroom modifications helped SWD gain access to STEM lessons. In addition, student ability level, lack of adult support, and time limitations were identified as barriers for SWD's participation in STEM lessons. Finally, teachers believe that professional development is needed in teacher collaboration and student disability knowledge. Teachers want the opportunity to work together during STEM lesson development and also during implementation of STEM lessons. Teachers also want to learn more about specific strategies for each disability category. The information gained should support teachers and school leaders with inclusivity of SWD in STEM lessons. / Doctor of Philosophy / Implementation of key instructional practices for STEM lessons can improve inclusivity for SWD. Knowledge of barriers and desired professional development can also increase inclusiveness.

STEM lessons can offer opportunities for K–12 students to engage in 21st-century skills and the 5 C's (citizenship, collaboration, communication, creativity, and critical thinking), which are skills that are desired for college and career readiness and for competition in a global economy. Through a basic qualitative study involving 13 teachers (5 elementary, 4 middle, and 4 high school) from 12 schools, information about SWD's participation in STEM lessons was gained. Findings suggest that knowledge of the SWD, building relationships, use of support staff and others, intentional grouping, assigned group roles, hands-on learning, and classroom modifications helped SWD gain access to STEM lessons. In addition, student ability level, lack of adult support, and time limitations were identified as barriers for SWD's participation in STEM lessons. Finally, the results revealed that teachers believe that more professional development is needed in teacher collaboration and student disability knowledge. Teachers want the opportunity to work together during STEM lesson development and also during implementation of STEM lessons. Teachers also want to learn more about specific strategies for each disability category.

This study assessed effectiveness of the Dunn-Seiler Museum's Omeka Virtual Platform by comparing student learning after virtual and hands-on informal outreach activities. The research, conducted in two Mississippi middle schools, focused on students’ (N=99) content gains and affective responses when engaging with fossil specimens that illustrate shifts in sea levels in Mississippi’s geological past. Data were categorized into three sections: content, affective response, and drawing portion. This mixed-methods research encompassed scoring student tests, coding student drawings, and identifying stable themes through teacher interviews. Analysis of pre-and post-tests for Control (hands-on) and Experimental (virtual specimens) groups revealed no significant differences in content gain or affective response when the data were aggregated for Control versus Experimental groups. Five themes emerged from qualitative analysis of teacher interviews, including teachers’ perceived importance of classroom novelty. Findings indicate that virtual fossil specimens offer a comparable experience to hands-on specimens in the context of museum outreach.

The dynamics of successfully integrating science, technology/engineering and math content, practice, and delivery in K-12 education is still evolving. "A number of questions remain about the best methods by which to effectively teach engineering at the K-12 level and how they play into the integration of other STEM disciplines" (Moore, Glancy, Tank, Kersten, Smith, and Stohlmann, 2014). The International Technology and Engineering Educators Association (ITEEA) has declared that technology and engineering within STEM education as delivered by the technology education content area is defined by the Standards for Technological Literacy™ (ITEEA, 2000). Lack of applied technology/engineering pedagogical content knowledge via technology teacher collaboration may be excluding valuable contributions to more effective STEM teaching and learning. Absence of developed and identified perceptions resulting from such collaborations could be an impediment to application of valuable technology/engineering practices, beliefs, content, and structure within integrated STEM instruction. Collaboration inclusive of all STEM subject teachers is critical to effective practice and delivery of integrated STEM teaching. To achieve this, integrated STEM experiences need "to be researched and evaluated to build knowledge and understanding about the effectiveness of these experiences in promoting STEM learning and engagement within and across disciplines." (Honey et al., 2014). The purpose of this study was to examine and identify science, math, and technology education teacher perceptions of technology/engineering education influence within existing STEM collaborations. The objective was to provide useful information pertinent to further improving STEM education practice and effectiveness. A three round, mixed method, Delphi approach was employed to determine common perceptions among all STEM teachers included in this study. Consensus among study participants identified strategies specific to technology/engineering education that were perceived to positively impact STEM education. The results of this study illustrate that content, practice, and pedagogical attributes specific to technology education do exist and that those attributes are perceived to enhance student learning of STEM content and practice. Synthesized from initial qualitative responses in Round One, of the 28 presented technology/engineering strategies, 24 achieved consensus as determined by an applied two factor threshold of a 7.5 median agreement score and interquartile rating of 2.0 or less from among all participants. In a comparison of represented STEM subjects taught, there also appeared significant agreement among all groups. The level of agreement between science and the other groups was weakest, although still sizeable. Engineering design knowledge, skilled use of tools and materials to produce models and prototypes, promotion of designerly critical thinking and problem-solving skills, and both tacit and contextual knowledge of technology and engineering applications were found to be general themes specific to technology/engineering education teachers. / Doctor of Philosophy / The acronym STEM as it applies to education represents a theoretical and practical construct inclusive of Science, Technology, Engineering and Math education. While seemingly a straight-forward concept, wide-spread practice of integrating all of the incorporated subjects is infrequently evident. Inclusion of technology and engineering education subject matter is most often absent in STEM teaching. A myriad of factors such as historical practice, unequal numbers of available teachers across all STEM subjects, longstanding academic tradition, structural and procedural paradigms of school management, and general resistance to change appear to impinge on development of STEM models inclusive of technology/engineering education. Content and practice of all STEM subjects can be both autonomous and interdependent. A challenge is to both recognize the existence of subject specific content and practice while also developing understanding of how interdisciplinary relationships between STEM subjects can enhance teaching and learning. Lack of applied technology/engineering pedagogical content knowledge via technology/engineering teachers included within STEM collaborations may be excluding valuable contributions to more effective STEM teaching and learning. While instances of STEM teaching inclusive of technology/engineering education are not common, they do exist. Research is needed to identify content and practices specific to technology/engineering education toward determining if those elements positively impact STEM education. The purpose of this study was to identify science, math, and technology education teacher perceptions of technology/engineering education when included within existing STEM collaborations. The objective was to identify strategies specific to technology/engineering education perceived to positively impact STEM education experiences. STEM teachers of all subjects having participated in fully inclusive collaborations served as study participants and were queried to determine consensus regarding strategies specific to technology/engineering education that were perceived to positively impact STEM education. The results of this study determined content, practice, and pedagogical attributes specific to technology education. Based upon initial qualitative responses in Round One, 24 of 28 identified technology/engineering education strategies were agreed upon as attributes primary to technology/engineering education. Several themes emerged from the 24 strategies. These themes included engineering design knowledge, skilled use of tools and materials to produce models and prototypes, promotion of designerly critical thinking and problem-solving skills, and both tacit and contextual knowledge of technology and engineering applications. In comparisons organized by subject matter, there appeared significant levels of agreement between each of the groups.

In science, technology, engineering, and mathematics (STEM) education, problem solving tends to be highly procedural, and these procedures are typically taught with general instructional text and specific worked examples. Instructional text broadly defines procedures for problem solving, and worked examples demonstrate how to apply procedures to problems. Subgoal labels have been used to help students understand the structure of worked examples, and this feature has increased problem solving performance. The present study explored using subgoal labels in instructional text to further improve learners’ problem solving performance. A factorial design examined the efficacy of subgoal labeled instructional text and worked examples for programming education. The results of the present study suggest that subgoal labels in instructional text can help learners in a different way than subgoal labels in worked examples. Subgoal labels in text helped the learner articulate the general procedure better, and subgoal labels in the example helped the learner apply those procedures better. When solving novel problems, learners who received subgoal labels in both the text and example performed better than those who received subgoal labels in only the example. Learners who received subgoal labels in only the example performed better than those who received subgoal labels in only the text and those who did not receive subgoal labels at all. The present study indicates that subgoal labeled instructional text can improve novices’ problem solving performance in programming, but subgoal labels must appear in both the text and example.
