Background: In research on design-based learning (DBL), inadequate attention is paid to the role the teacher plays in supervising students in gathering and applying knowledge to design artifacts, systems, and innovative solutions in higher education.

Purpose: In this study, we examine whether teacher actions we previously identified in the DBL literature as important in facilitating learning processes and student supervision are present in current DBL engineering practices.

Sample: The sample (N=16) consisted of teachers and supervisors in two engineering study programs at a university of technology: mechanical and electrical engineering. We selected randomly teachers from freshman and second-year bachelor DBL projects responsible for student supervision and assessment.

Design and method: Interviews with teachers, and interviews and observations of supervisors were used to examine how supervision and facilitation actions are applied according to the DBL framework.

Results: Major findings indicate that formulating questions is the most common practice seen in facilitating learning in open-ended engineering design environments. Furthermore, other DBL actions we expected to see based upon the literature were seldom observed in the coaching practices within these two programs.

Conclusions: Professionalization of teachers in supervising students need to include methods to scaffold learning by supporting students in reflecting and in providing formative feedback.  相似文献

ABSTRACT

This paper introduced how a mechanical engineering course was redesigned by applying experiential learning theory to improve student engagement and learning experience. Design of machine elements has been considered by students to be a difficult course. Traditional teaching methods tend not to be effective in engaging students. Experiential learning is a philosophy of learning by doing. In applying an experiential learning approach to the course, the design project and workshop activities were restructured in such a way that students were engaged in direct experience and focused reflection to construct knowledge. By exploring a physical gearbox model, working on subtasks for the design project, having group discussions, raising questions, getting feedback, and moving forward for next subtasks, students experienced the learning cycles of ‘DO, OBSERVE, THINK, and PLAN’ many times. Course survey results showed that application of experiential learning helped to improve student engagement and learning experience significantly.  相似文献

ABSTRACT

Collaborative design is recognised as being shaped by complex social, cognitive, material, and technical processes. In the case of design decision-making, however, the social dimension has yet to be fully understood as the product of the whole team dynamic rather than as simply the sum of the individual (cognitive) contributions. This paper examines the interactional work teams of first-time design students do that produces decisions in undergraduate engineering design projects. Close analysis of decision-making episodes, recorded in design meetings in a yearlong ethnographic study, reveals the joint social and situated work teams do to produce decisions. Students were found to do decision-making via three overlapping phases that were invariant across the database: (i) Design options emerge, (ii) teams orient to design options, and (iii) design decisions come off. This paper exemplifies these phases of decision-making as inherently – and not just incidentally – social, and illustrates how decisions are produced in novice design teams via these phases in multifarious ways. We argue for an explicit retrospective focus on the processes and consequences of team decisions following projects as an avenue for fostering the development of design judgment that engineering graduates will take into their professional practice.  相似文献

The two‐quarter Senior Design Project course given in the Computer Science and Engineering Department of Auburn University gives undergraduate students a significant computer system development experience by working on a project from proposal to prototype. Heavy emphasis is placed on team‐ and project‐management principles, team presentations, the application of standard structured development methodologies, and the generation of formal deliverables after each project phase. Project ideas are canvassed from faculty, graduate students, local industry and community, and from the students themselves. We believe that the knowledge and experience acquired by students from working in a team on a substantial project gives them an insight and perspective that is unattainable through the standard lecture paradigm. The course has received enthusiastic endorsement from industry, accrediting boards, and participating students (albeit at the end of the course!).  相似文献

ABSTRACT

Community colleges have long been recognized as pivotal institutions for broadening educational opportunity for a variety of marginalized populations, including first-generation students. These institutions are also an important starting point for students desiring to eventually earn a bachelor’s degree in a science, technology, engineering, or mathematics discipline. Our qualitative study explores the experiences of 15 first-generation community college transfer students majoring in engineering. We use the theory of community cultural wealth and the concepts of experiential capital and transfer student capital as lenses for analyzing and interpreting our semistructured interview data and for formulating recommendations to improve the transfer experiences and educational outcomes of this population. This sample of students enacted several types of community cultural wealth and experiential capital when navigating the engineering transfer pathway and in their engineering studies. They were less likely to enact the elements of transfer student capital, however. Instead, our results indicate that the participants attribute their successful transitions to their self-motivation and initiative associated with community cultural wealth and experiential capital, rather than institutional interventions associated with transfer student capital. We conclude with recommendations for strengthening institutional programs directed at first-generation engineering transfer students.  相似文献

ABSTRACT

Clubs constitute a prominant co-curricular activity to prepare students for effective professional careers, yet the role of engineering clubs in students' professional formation is poorly understood. This qualitative, comparative case study investigated three student engineering clubs at a large American public university. The clubs included a domestic chemical reaction car competition; a formula racing club that partners with a German team and competes both domestically and internationally; and a humanitarian engineering club centred on service learning projects in developing countries. Data collection included semi-structured interviews with participants (N?=?19) and observations of club work sessions (N?=?27). Using Cultural Historical Activity Theory (CHAT) as the analytical framework, the transcribed interviews were coded to characterise the activity in each club. The findings demonstrate that a confluence of elements, especially decision-making rules and division of labour, leads to a fundamentally distinct activity system in each club. Consequently, each club differs in the ways it influences students’ professional formation. More generally, this study illustrates the potential of CHAT for analysis of co-curricular activity that can lead to alternative approaches to activity design.  相似文献

Abstract

Mathematicians use example generation to test and verify mathematical ideas; however, the processes through which undergraduates learn to productively generate examples are not well understood. We engaged calculus students in a teaching experiment designed to develop skills in productively generating examples to learn novel concepts. This article presents three student case studies. These case studies are representative of our findings and serve to summarize the activities we found useful. They also serve as examples of various student experiences during the teaching experiment. One student expressed a continued negative view to using example generation. Two increased in skills and experience and expressed positive changes in views.  相似文献

The design and implementation of autonomous robots provides experience with engineering problems as well as with hard problems in artificial intelligence. Our aims in this article are fourfold: First, we describe how the use of robots complements traditional classroom lectures for the teaching of important concepts in a graduate‐level AI class. Second, we discuss the use of robots as a multimedia tool for capturing student interest and facilitating the self‐guided exploration of AI concepts. Third, we relate readings and robots in the curriculum and show how the robots aid understanding of philosophical issues in AI. Finally, we describe the robot kits and the organization of the class, present several completed projects by student teams, and report some of the feedback given by students who completed the course. We also analyze the successes and failures of the first two courses offered and describe the changes made for the recently completed second course.  相似文献

High-School Students' Attitudes Regarding Procedural Abstraction   总被引：1，自引：0，他引：1  
During the last decade a new computer science curriculum has been taught in Israeli high schools. This curriculum introduces CS concepts and problem-solving methods independently of specific computers and programming languages, along with the practical implementation of those concepts and methods encountered in actual programming languages. The advanced study unit of the curriculum, Software Design, introduces the students to various aspects of software systems design through the use of abstract data types (ADTs). One main goal of the unit is to develop abstract thinking skills and problem-solving abilities. More specifically, the unit presents principles such as procedural abstraction, data abstraction, information hiding, modularity, efficiency, and reuse of code.We present the results of a preliminary study whose aim was to assess students' attitudes regarding procedural abstraction. The research population consisted of high-school students who attended the Software Design course (beginners), and a control group of undergraduate CS students (advanced). The results of the study clearly indicated a significant difference between the attitudes of the two groups. We found that the advanced students preferred algorithms that were formulated to some extent with high-level abstraction; however, they encountered a cognitive barrier when dealing with algorithms that they had evaluated as too abstract for them. However, beginners felt more comfortable with algorithms with low-level abstraction. Nevertheless they showed open-mindedness toward some degree of procedural abstraction. The results of the study were used to design scaffolding problem-solving tools for algorithm development, utilizing procedural abstraction techniques that can be adapted to various student populations (Haberman, B. (2002) SIGCSE Bulletin, 34(4), 60–64).  相似文献

ABSTRACT

The present study investigated the effects of online argumentation scaffolding on students’ argumentation involving hypothetical and theoretical biological concepts. Two types of scaffolding were developed in order to improve student argumentation: continuous scaffolding and withdraw scaffolding. A quasi-experimental design was used with four 8th-grade classes comprising a total of 124 students. Two classes (63 students) were assigned into the continuous scaffolding group, while the other two (61 students) were assigned into the withdraw scaffolding group. All the students participated in online argumentation regarding four units, including two hypothetical concepts and two theoretical concepts. Both online learning process and scientific argumentation assessment results indicated that the continuous scaffolding group performed significantly better in terms of the quality and quantity of argumentation than the withdraw scaffolding group with regard to the hypothetical biology concepts, particularly in generating rebuttal arguments. In addition, the results also showed that both the continuous group and withdraw group students had better argumentation performance with regard to the hypothetical biology concepts than the theoretical biology concepts. Taken together, the study results suggest that learning argumentation through theoretical biology concepts is more difficult than doing so through hypothetical biology concepts.  相似文献

Abstract

This study assessed 4th, 8th, and 11th grade students' understanding of natural and social science concepts related to pollution. A representative sample of public school students (n = 105) in 11 Maine schools was selected, and students were interviewed on four concept principles considered critical to a full understanding of the pollution problem. The concept of pollution included the much publicized issues of solid and toxic waste as well as air, soil, and water pollution. Research assertions were summarized in generalized correct concept statements indicating the extent of current student knowledge. Common misconceptions were also noted.

This study considered student understanding from a human ecological perspective, that is, as an integrated set or cluster of concepts related to pollution. This reflects a complex, integrated, and multidisciplinary conception of natural phenomena. Human constructivism, meaningful learning theory, and principles related to the relevance of student schema in the design of curriculum and instructional strategies guided this work.

The results of this study have implications for teaching about pollution and the design of science education curriculum materials based upon student knowledge. This information can guide teaching strategies concerning current environmental problems and thus help learners gain an appreciation for the complex and multi-disciplinary nature of science, technology, and society and how they affect the environment.  相似文献

Background: Nationally, many public universities have started to move into the online course and program market that was previously associated with for-profit institutions of higher education. Public university administrators state that students seek the flexibility of online courses. But do students want to take courses online, especially freshmen-level science courses perceived to be difficult?

Purpose: This study investigated student views related to the potential of a physics course they were currently enrolled in being offered online.

Sample: This study took place at a large, public, mid-western university and involved students enrolled in either the first or second semester of a face-to-face flipped physics course for engineering technology majors.

Design and methods: Discussions with students during the semester about their online course experiences and expectations were used to develop the concourse and subsequently the Q sample to perform a Q methodology study about students’ views regarding taking physics courses online. Additional statements for the concourse and Q sample were taken from communications with administrators at the university. In this way, the statements sorted by the students included those from students and those from administrators. Factor analysis of the Q sorts resulted in three factors, each representing a unique perspective. Interpretations of these perspectives included the analyses of the Q sorts, the researcher’s interactions with students and administrators, and students’ written responses regarding their previous online course experiences and their sorting decisions.

Results: Three unique student views emerged were named: keeping it real and face-to-face, Online could be ok depending upon the course and instructor, and Online not for STEM classes. Consensus among the views is also discussed.

Conclusions: Overall, students’ views are negative concerning having physics courses, including labs, online and those views conflict with statements expressed by administrators regarding students’ desires for online courses at the university.  相似文献

Industrial software development today requires a fundamental education in computer science as well as the ability to work productively and collaboratively in a team environment. Employers will therefore favor graduates who have mastered computer science and software engineering concepts and can apply them while developing a software system. To produce computer science graduates possessing the skills necessary to succeed in the workplace, team‐oriented software engineering courses with real projects (and with real clients) are increasingly emphasized. It is, however, difficult to successfully present a software engineering course that covers software engineering concepts and offers opportunities to apply them during a project in a team environment. The difficulties lie in project selection, team formation, team and project organization, process management, and, finally, grading. The objective of this article is to discuss these difficulties and provide suggestions for alleviating or avoiding them.  相似文献

Abstract

This study assessed the level of scientific and natural resource knowledge that fourth-, eighth-, and eleventh-grade students in Maine possess concerning acidic deposition. A representative sample of public school students (N = 175) was interviewed on twelve concept principles considered critical to a full understanding of the acidic deposition problem. These included geological, meteorological, ecological, political, and economic concepts. Student knowledge was rated for each concept principle on a scale of complete, high partial, low partial, or no understanding. Common misconceptions were also noted. Generalized correct concept statements of current student knowledge are reported, as well as generalized missing concepts. Our conclusions have implications for teaching about acidic deposition and the design of environmental education curriculum materials based upon student knowledge. This information can help teachers better instruct students about current environmental problems and thus help learners gain an appreciation for the complex and multidisciplinary nature of science and the environment.  相似文献

ABSTRACT

Feedback is an important part of design education. To better understand how feedback is provided to students on their engineering design work, we characterised and compared first-year engineering students’, undergraduate teaching assistants’, and educators’ written feedback on sample student design work. We created a coding scheme including two domains: Substance and Focus of feedback. Educators made more and longer comments than undergraduate teaching assistants, and undergraduate teaching assistants made more and longer comments than first-year students. The first-year students focused on giving specific directions in their feedback while educators and undergraduate teaching assistants asked thought-provoking questions. Students tended to make more comments about the ways that their peers had communicated their design work while educators and undergraduate teaching assistants made more comments about the design ideas presented in the sample work. This study offers implications for practice for supporting educators, undergraduate teaching assistants, and first-year engineering students to be able to provide feedback on design work.  相似文献

Recent reforms in science education have supported the inclusion of engineering and their practices in K-12 curricula. To this end, many classrooms have incorporated engineering units that include design challenges. Design is an integral part of engineering and can help students think in creative and interdisciplinary ways. In this study, we examined students’ conceptions of design during and after participation in a design-based science curriculum unit. Our study was guided by the following research question: What are students’ views of design after participation in an engineering design-based science curriculum unit and how are these views reflected in their enactment throughout the unit? Using a qualitative approach, we examined students’ conversations throughout the enactment of the curriculum and interviews conducted after the completion of the unit. We found that students had complex and diverse views of design, and these views were reflected in their group discussions throughout the curriculum and design challenge. Students most frequently expressed design as learning and as a process of integration into a coherent whole. These aspects of design were also frequently observed in students’ conversations during the unit. Interestingly, we found evidence of students demonstrating several aspects of design throughout the curriculum that were not explicitly expressed during the student interviews. Taken together, these findings support the complex nature of design as seen at the middle school level.

Background: Globalization, technological advancement, environmental problems, etc. challenge organizations not just to consider cost-effectiveness, but also to develop new ideas in order to build competitive advantages. Hence, methods to deliberately enhance creativity and facilitate its processes of development must also play a central role in engineering education. However, so far the engineering education literature provides little attention to the important discussion of how to develop knowledge intensive ideas based on creativity methods and concepts.

Purpose: The purpose of this article is to investigate how to design creative camps from which knowledge intensive ideas can unfold.

Design/method/sample: A framework on integration of creativity and knowledge intensity is first developed, and then tested through the planning, execution and evaluation of a specialized creativity camp with focus on supply chain management. Detailed documentation of the learning processes of the participating 49 engineering and business students is developed through repeated interviews during the process as well as a survey.

Results: The research illustrates the process of development of ideas, and how the participants through interdisciplinary collaboration, cognitive flexibility and joint ownership develop highly innovative and knowledge-intensive ideas, with direct relevance for the four companies whose problems they address.

Conclusions: The article demonstrates how the creativity camp methodology holds the potential of combining advanced academic knowledge and creativity, to produce knowledge intensive ideas, when the design is based on ideas of experiential learning as well as creativity principles. This makes the method a highly relevant learning approach for engineering students in the search for skills to both develop and implement innovative ideas.  相似文献

Abstract

Promoting student agency has been seen as the primary function for new generation assessment environments. In this paper, we introduce two models of self-assessment as a way to foster students’ sense of agency. A socio-cultural framework was utilised to understand the interaction between student agency and self-assessment. Through a comparative design, we investigated whether formative self-assessment and summative self-assessment, based on self-grading, would offer students different affordances for agency. The results show that while both models offered affordances for agentic learning, future-driven agency was only presented by the students studying according to the summative model. Our results shed light on the interplay of student agency and self-assessment in higher education.  相似文献
