WPI’s global and off-campus IQPs, rich with real-world sponsors/projects and increasingly diverse teams, require that both faculty and students navigate a network of ambiguous situations and relationships. Despite the increasing adoption of project-based learning as a preferred educational model across higher education, and the prevalence of project-based work in STEM careers, research on how to best prepare students and faculty to identify and navigate ambiguity inherent to project-based learning is limited. Seeking to fill this important gap, this graduate thesis advances a pilot qualitative study focused on how students in domestic and off campus IQPs experience and navigate ambiguity in their IQPs. The thesis presents preliminary grounded theory regarding the types of ambiguity experienced by students, how students navigate through the ambiguity, and elements that appear to impact a student’s success in that navigation.

The dominant pedagogy for engineering educations still remains chalk and talk despite the large body of education research that demonstrates its ineffectiveness. Traditional approaches to structural engineering education place a heavy emphasis on lecture-based delivery of the theories of structural analysis and the behaviour of common constructions materials. Design projects are given varying emphasis at different institutions, but are frequently left to the final year of the course. Assessment weighting often heavily favours examinations over project work. In recent years, the engineering profession and the bodies responsible for accrediting engineering programs have called for change in assessment and teaching practices.This study proposed that the use of design projects in structural engineering is an effective method of learning that models industrial practice. Projects enable students to understand the synthesis of structural analysis, material behaviour and availability, constructability and economic reality that occurs in the professional practice of structural engineering. To examine effectiveness of project-based learning in structural engineering a case study was undertaken in a third year undergraduate course of a civil engineering program in South Australia.This thesis first provides some background to structural engineering and current practice in structural engineering education. Project-based learning as applied to engineering is also examined. The case study design and data collection are then discussed. The study was developed around a conceptual framework for educational evaluation that differentiates between the intended, implemented, perceived and achieved curriculum. The intended curriculum, defined as the original vision underlying a curriculum, was developed through a literature review that considered the requirements of industry and ++ / engineering accreditation bodies. The degree to which the intended curriculum was successfully implemented in the course was evaluated through video-tapes of lessons, journal records and interviews. The actual learning experiences as perceived or experienced by the students, was evaluated through student journals, interviews and two questionnaires, one of which was also administered to a senior structural engineering industry group to enable a comparison between the student and industry groups perceptions of the importance of certain skills in the engineering profession. The achieved curriculum, defined as the resulting learning outcomes of the students, was also examined. The thesis concludes with a discussion of the findings of the study as well as their significance and limitations and then considers the possible extensions of project-based learning to other areas of engineering and some of the issues that will need to be addressed for this to occur.

The purposes of the research which is based on the framework of knowledge management whose five dimensions are knowledge gaining, depositing, sharing, applying and innovating are divided into two parts. First, under the framework of knowledge management, evalueate how junior school students perform towards each dimension. Second, discuss the reasons and effects from the information of questionnaires. And, from five dimensions of the framework of knowledge management, analyze different behaviors on blogs of junior school students and various factors of influences in this survey. The method is mainly by qualitative research and auxiliarily by quantitative research. The study subjects consist of 59 students in the weekend project-based learning class of academic year of 2006 in Guo-Guang Laboratory School,NSYSU. The research time was from September in 2006 to August in 2007. Based on the five dimensions of the framework of knowledge management, we can draw conclusions as follows. First, the gaining of knowledge was mostly from the internet and also others¡¦ blogs. If it was from academic books, we would surely gain knowledge of higher levels. Second, it was easy to deposit gained knowledge on blogs. However, it would be a better deposition after systematically sorting. Also, blogs which kept tracks of learning struggles efficiently could produce metacognitions. Third, on blogs, students were looking forward to others¡¦ responses. However, the course was limited in excessively close relationships and some factors. As a result, sharing behaviors were not quite frequent. Blogs made distance closer and turned one way construction of knowledge into mutual. Building internet groups on blogs tended to produce the common languages and impelled us to apply knowledge. It took more psychology levels to innovate knowledge and needed higher spontaneous motivations to learn.

The goal of this work is to modify an existing course module on engineering better medicines to produce a more engaging physiologically realistic and pedagogically sound curriculum. The original module explored drug delivery using a one-compartment model, which examined only the dissolution of medicine; the module relied on a traditional teacher lead pedagogy. The curriculum modifications include engineering a two-compartment model students use to test the medicines they design, incorporating both dissolution and transfer to the blood and project based learning strategies have been added to produce a student centered project. The purpose of these modifications is to produce a curriculum successful in providing a diverse group of students, both male and female, of all socioeconomic backgrounds as well as ethnic and cultural groups with a positive engineering experience. / text

To address the need to improve student achievement in STEM disciplines, effort has been made to develop a new of tools for STEM education (Bybee, 2013). The Robotics and Engineering Design Curriculum (REDC) provides students an opportunity to develop systems thinking abilities while integrating science and mathematics concepts. Using an exploratory case study approach within a situated cognition framework, this study examines the effects of using REDC on 54 eighth grade students’ performance and engagement during 5-week integrative STEM instruction in the mathematics and science class. Situational factors that contribute to students’ success in learning STEM concepts are also examined. This study employed mixed-methods techniques. The quantitative data collected included pre/post achievement tests and pre/post motivation and engagement scale (MES) surveys. Quantitative data analysis included reliability analyses and paired sample t-tests. The results of the reliability analyses for the achievement test and MES survey report acceptable Cronbach’s alpha (.843 and .787, respectively). Qualitative data collected included semi-structured interviews, field notes and student artifacts (engineering notebook and printed prototypes). Qualitative data analysis used coding procedures suggested by Saldana (2012) where patterns were identified and grouped to allow the emergence of themes. Collectively, the data was triangulated to support six emerging themes. The emerging themes regarding the effect of using the curriculum are as follows: (1) the developing anthropomorphic relationship with the robot enhances engagement, (2) engagement is impacted by purposeful and intentional physical action, and (3) purposeful collaboration promotes engagement through the construction of meaning and interaction. Three themes emerged identifying factors that contribute to success: (1) learning environment must have transformative learning potential, (2) learning experiences underpinned by design thinking contribute to success and (3) contextual relevance is enhanced when students have the freedom to their design learning journey. This study addresses the need for research into the implementation of 3-D design and manufacturing in the middle school classroom. Bybee, R. W. (2013).

This dissertation consists of three articles that explore the effect of professional development (PD) on teachers‘ understanding and implementation of Science, Technology, Engineering, and Mathematics (STEM) project based learning (PBL), and the effect of STEM PBL on students‘ mathematics achievement. Teachers in three high schools participated in the research activities. They attended sustained PDs provided by one STEM center based in a Southwestern university, and were required to implement STEM PBLs once every six-weeks for three years (2008 through 2010). The first article employed a mixed-method case study to explore the relation between the quality of the teachers‘ in-class STEM PBL implementations, understanding of the PBL in STEM education, and attendance in the STEM PBL activities. Quantitative findings indicate that attendance in the PD activities was significantly correlated with the quality of the in-class PBL implementation in 2010, yet not in 2011. Moreover, qualitative findings show that the teachers viewed the STEM PBL pedagogy as a means to promote student interest in mathematics, cultivate the interdisciplinary research culture in K-12 classrooms, and help improve students‘ content understanding. The second article investigated the effect of STEM PBL, especially on Hispanic and at-risk students‘ mathematics achievement. The participants were 528 students in the three STEM PBL high schools and 2,688 students in non-STEM PBL schools in the same region. Latent growth modeling was used to analyze the repeated measures across years. STEM PBL instruction positively influenced Hispanic students‘ achievement in mathematics, but not at-risk students. The third study investigated whether participating in STEM PBL activities affected students who had varied performance levels, and to what extent students‘ individual factors influenced their mathematics achievement. The participants were 836 high school students in the three schools. The findings from the hierarchical linear modeling showed that low performing students showed statistically significantly higher growth rates on mathematics scores than high and middle performing students, over the three years. In addition, student‘s ethnicity and economic status were good predictors of academic achievement. This dissertation is the first to reveal the effect of STEM PBL on student academic achievement relating to inservice teacher PD by employing the sophisticated research methodology.

Project work has gained a prominent place in research for its significant educational potential (Blumenfeld et al., 1991; Fallik et al., 2008). Teachers, however, have not been providing project work with a prominent place in the elementary classroom (Blumenfeld et al., 1991; Fallik et al., 2008; Rogers et al., 2010; Tse, Lam, Lam, & Loh, 2005). To encourage and support teachers in practicing Project-Based Learning (PBL), we need to understand what motivates teachers to enact PBL, the challenges they face in doing so, and ways to support teachers in overcoming these challenges. To examine teachers’ lived experiences in enacting student-centered project work, the current study used the method of participatory action research (PAR). This method included the active participation of a teacher (Megan) and me (the principal researcher) in the design, enactment, and reflection upon a constructivist, whole-class project in an eastern Ontario Grade 5 classroom. The study was structured around two research questions: (1) what did we perceive as challenges and benefits of organizing and enacting a student-centered project, and (2) how did we perceive that our collaboration in organizing, enacting, and reflecting upon this project impacted our thinking and practices with regard to project work? Megan’s and my reflections were collected over the course of the project through two semi-structured interviews, diary writings, a pre-structured planning journal, and three semi-structured discussions. Megan and I perceived project work as beneficial to students’ engagement and learning. Enacting the project was challenging, as we lacked the management and organizational skills to enact project work efficiently, and we possessed a strong desire to control the direction of the project. Megan and I were further challenged by students’ lack of skills and comfort with the project’s demands and the lack of school support and time we needed for the project. Collaboratively experiencing and reflecting upon the project demonstrated how essential these challenges were in increasing Megan’s and my comfort, appreciation, understanding, and skills in enacting project work. Based on these findings, the study encourages teachers to collaboratively design, experience, and reflect upon project work in the context of their classrooms. / Thesis (Master, Education) -- Queen's University, 2012-04-09 16:30:00.451

Master of Science / Food Science Institute / Justin Kastner / Student success in today’s modern, technological world depends on a thorough understanding of Science, Technology, Engineering and Math. The US has made efforts to promote STEM education in recent years which has raised the international ranking of the United States students in STEM disciplines; however, more work is needed to make the US a leader in STEM education. Many methods have been used to help increase student interest and success in STEM disciplines. An integrated curriculum is one such method to heighten STEM education by using multiple subjects to support the content being taught. Food Science can be used as a tool in integrated curricula to enhance STEM education. The universality, cultural importance, and scientific diversity of food make it a perfect fit to incorporate content from all STEM disciplines. Furthermore, exposing students to the complexity of the food chain, food safety, and food science at a young age sets them up to be informed and educated consumers throughout their lives. The curriculum prototype developed for this report demonstrates the continuing promise of food science to enhance STEM education. This food-centric, project-based integrated curriculum encompasses all the standards required in fifth-grade science and math in the state of Tennessee with the added benefits of incorporating knowledge of food safety and the realities of the food chain. This curriculum is based on the essential question of how to use a community garden to bring nutrition to the people of Southern Asia. Through dissecting this problem, students learn about geographic diversity, plant growing conditions, food harvesting and preservation techniques, and cost implications to complex problems. Furthermore, the content required in 5th grade math and science in Tennessee is incorporated so that students learn the required content while solving a complex, real-world issue. The use of food science in integrated curricula provides students with hands-on experience in STEM subjects in a way that encourages independent learning, student engagement in the content, and real-world learning experiences. For students to have success in the modern world, they need a clear understanding of how the material presented in STEM courses relates to their lives. Food science can be used to enhance STEM education in a way that engages students and highlights important learning principles in science, technology, engineering, and math. Food science can elevate STEM education, increase student interest in STEM, and cultivate an engaged and knowledgeable public.

Doctor of Philosophy / Curriculum and Instruction Programs / Rosemary S. Talab / The goal of this exploratory case study was to answer two questions: 1. How does an exemplary on-campus undergraduate large Introduction to Cultural Anthropology course encompass the PBL learning model characteristics, specifically focusing on the following: 1.1) Driving question, 1.2) Student construction of an artifact, 1.3) Teachers’ role, and 1.4) Assessment? 2. How is technology used by the professor, teacher assistants, and students to support project-based learning? To answer these questions, the researcher studied a large Introduction to Cultural Anthropology class, which consisted of the professor, ten teaching assistants (TAs), and 400 students. The students were divided into 20 recitation sections, with 20 students in each section. Each TA was assigned two recitation sections. Observations were conducted on twice-weekly Professor’s lectures and three once-weekly recitation sessions. Additionally, interviews and follow-up interviews were conducted of the professor, three teaching assistants (TA), and nine students. Finally, documents analyzed included the professor’s course materials and course management documents. With respect to Research Question 1, “How does an exemplary on-campus undergraduate large Introduction to Cultural Anthropology course encompass the PBL learning model characteristics, specifically focusing on the following: 1.1) Driving question, 1.2) Student construction of an artifact, 1.3) Teachers’ role, and 1.4) Assessment?”, research findings indicated that all four elements of the PBL model were present in this class and were executed well. Research Question 2, “How is technology used to support PBL,” findings indicated that advanced technologies were used by the professor for course purposes. These technologies included Wetpaint (the wiki course management system) and Facebook. More conventional technologies, such as e-mail, were also used for this purpose. Though students were hesitant to use course technology in the beginning. However, with the help of the professor and TA’s, the students learned to use the course technology and grew to enjoy it. Two additional themes emerged through open coding: Emotional Involvement and Non-Participation. First, the TA’s and students developed emotional ties to the cultures that they created in their recitation sections. Second, some students did not participate in either the lecture or the recitation sessions. The TAs took non-participation seriously, both in terms of class participation, individually, and in terms of student responsibilities to the group recitation session in culture construction.

Consumer Studies is a valuable and multifaceted subject in South African schools, requiring that teachers in the subject are well prepared. Pre-service Consumer Studies teachers need to be prepared to become lifelong learners to cope with the dynamic nature of the subject, as well as to develop various 21st century skills to be able to deal with the demands of these times. Structured guidance, however, could not be uncovered for the preparation of pre-service Consumer Studies teachers to empower them with the requirements for Consumer Studies education. Sett-directed learning is a process that supports the developn1ent of various 21st century skills, including lifelong learning, and could thus contribute to the development of preservice Consumer Studies teachers, if included in their preparation. A suitable teaching-leaming strategy that could be utilised in the preparation module for Consumer Studies teachers, as well as a vehicle to promote self-directed learning as part of such preparation, was identified in the form of project-based learning. A qualitative case study was employed to investigate how project-based learning as a teaching-learning strategy could promote self-directed learning in a pre-service Consumer Studies teacher preparation module. Project-based learning was found to foster the development of various skills as part of the process, including planning and collaboration skills. Subject content, consistent with what is required to be taught in Consumer Studies education on high school level, was developed and self-directed learning was promoted in participants using project-based learning. Recommendations were suggested for the preparation of pre-service Consumer Studies teachers, as well as for the effective structuring of projects and project-based learning in Consumer Studies. / MEd (Curriculum Development), North-West University, Potchefstroom Campus, 2015
