The large potential of lead users (LUs) in developing innovative and radically new product concepts is well established in the literature. However, in a widely acknowledged study, Hoffman et al. introduced the new concept of emergent‐nature consumers (ENCs) and showed the superiority of this group of individuals over LUs in developing new product concepts. Consequently, they postulated ENCs to be “the right consumers” to be integrated in new product development processes. In this article, we critically reflect and build on Hoffman et al.'s study and further investigate the promise of the ENC concept as compared to the LU concept. In a pilot study, we replicated the study by Hoffman and colleagues: We conducted a crowdsourcing competition and asked for concepts for new services; those concepts had been generated collectively by the participants and had been assessed by a consumer crowd. In the main study, the participants of a crowdsourcing competition submitted individually generated concepts for products, which were evaluated by industry experts. Across both studies, using different empirical methods in two different contexts, and in contrast to Hoffman et al.'s work, we find support for LUs outperforming ENCs (as well as average users) in generating the commercially most promising concepts. Thus, our insights reinforce the existing user innovation literature and the notion of LUs being the primary source of new product/service concepts.  相似文献

Integrating engineering and technology concepts into K-12 science and math curricula through engineering design project-based learning has been found to increase students’ interest in science, technology, engineering, and mathematics (STEM), however preparing teachers to shift to interdisciplinary teaching remains a significant challenge. Primarily teachers need to develop both skills and attitudes toward interdisciplinary teaching. In doing so, professional development (PD) is considered a key component in helping teachers through this transformation process. In an educational environment of accountability, measuring the effects of PD programs on teacher behaviors and capacity is essential but often elusive. The current study describes the change in attitudes to interdisciplinary teaching of 29 self-selected middle and high school teachers who participated a PD workshop and in delivering a 12–15 week interdisciplinary teaching and design problem unit that spanned multiple STEM subjects. This quasi-experimental pilot study implemented a single group pretest–posttest design using survey methods to collect data from the participants at two intervals; at the time of the PD workshop and at the completion of the teaching unit that emphasized a long-term engineering design problem. The goals of this research are to (1) assess the changes in attitudes to interdisciplinary teaching, attitudes to teamwork, teaching satisfaction, and resistance to change, (2) explore relationships among these changes, (3) and describe the variation in these changes across teachers’ gender, school level, discipline taught, and education level.  相似文献

This article focuses on one way to study technology, through technological problem solving situated in real-life contexts. In problem solving for real-life contexts, design processes are seen as creative, dynamic and iterative processes that engage exploration; join conceptual and procedural knowledge-both thought and action; and can encourage considerations to technology, human and environmental interactions. This approach is a demarcation from what is typically found in schools; design, make and appraise cycles based on closed design briefs that are teacher assigned and unrelated to the students' world. An interpretation of technology education as problem solving for real-life contexts using design processes as tools for creation and exploration offers an alternative approach to design in technology education. Alternative curriculum and instruction then emerge. Elementary and secondary school programs in technology education and teacher education can all be seen through this kind of design lens. Episodes from case studies are reported with the intent to briefly describe technology education programs in elementary and secondary schools that interpret technology education in this way. Educational implications of this approach are offered. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

With the rapid advances in civilization, technological breakthroughs, and a globally growing workforce, there is a strong need for engineers capable of working in the 21st century environment (Galloway, The 21st century engineer: A proposal for engineering education reform. ASCE, Washington DC 2008). To help increase the quality and quantity of students choosing to pursue engineering, leaders have called on K-12 education to look for methods of inserting pre-engineering into the K-12 curriculum. Leaders in technology education have responded to the call to develop top quality candidates for engineers by infusing engineering into the technology education curriculum. Teacher preparation programs have used various methods to provide future technology teachers with the required content knowledge in order to effectively teach engineering design within the technology curriculum. One such program uses an ABET accredited engineering curriculum for the content and additional training to strengthen engineering education pedagogy for technology teachers. Students who graduate from this program possess both an engineering degree and technology teaching license. The purpose of this investigation was to ascertain the differences between technology teachers from this program and traditionally trained technology teachers. In particular, how each group incorporates the engineering design process in classroom assignments. Design briefs were gathered from pre-service teachers who graduated from the aforementioned program and compared to design briefs of practicing technology teachers around the United States. The engineering design process was used to develop a rubric to compare the usage of engineering content between the two groups. It was found that students with 4 years of engineering training were more likely to use all steps of the engineering design process. Further examination illustrates that engineering trained technology teachers were significantly more likely to use mathematical and analytical methods to determine optimum solutions. In order for technology education teachers to effectively infuse engineering design into coursework, they need to be familiar and comfortable with the engineering sciences and the design process. With limited engineering design experience, technology teachers are not as likely to use optimization techniques involving mathematical and analytical reasoning. These concepts are critical for engineering students to be successful in college engineering programs and beyond.  相似文献

This paper examines recent research in student learning of technological concepts and processes. To explore this area three inter-related aspects are considered; existing concepts of technology, technological knowledge and processes. Different views of technology and technology education are reflected in both research outcomes and curriculum documents. Teacher and student perceptions of technology impact on the way in which technology is undertaken in the classroom. Teacher's perceptions of technology influence what they perceive as being important in learning of technology. student's perceptions of technology and technology education influence what knowledge and skills they operationalise in a technological task and hence affect student technological capability. Technological concepts and processes are often defined in different ways by particular groups. Subject subcultures are strongly held by both teachers and students. The influence of subject subcultures and communities of practice will be discussed in terms of defining and operationalising technological concepts and processes. Technological concepts are not consistently defined in the literature. For students to undertake technological activities, knowledge and processes cannot be divorced. Recent research highlights the problems when processes are emphasised over knowledge. This paper will examine different technological concepts in an attempt to create a critical balance between knowledge and process. Much of the literature in technology education has rightly emphasised definitions, curriculum issues, implementation and teacher training. This paper argues that it is now time to place a great emphasis on in-depth research on student understanding of technological concepts and processes and ways in which these can be enhanced.  相似文献

Philosophy of technology is a discipline that has much to offer for technology education. Insights into the real nature of technology and its relationship with science and society can help technology educators to build a subject that helps pupils get a good concept of technology and to learn to understand and use concepts in technology. Here the way science educators have gained from the philosophy of science, for example in the idea of the way pupils learn concepts by reconstructing pre-concepts that they picked up from daily-life experiences. Research has shown that the learning of concepts and the learning of process skills have to be connected.  相似文献

Design-based learning (DBL) is an educational approach grounded in the processes of inquiry and reasoning towards generating innovative artifacts, systems and solutions. The approach is well characterized in the context of learning natural sciences in secondary education. Less is known, however, of its characteristics in the context of higher engineering education. The purpose of this review study is to identify key characteristics of DBL in higher engineering education. From the tenets of engineering design practices and higher engineering education contexts we identified four relevant dimensions for organizing these characteristics: the project characteristics, the role of the teacher, the assessment methods, and the social context. Drawing on these four dimensions, we systematically reviewed the state-of-the-art empirical literature on DBL or DBL-like educational projects in higher engineering education. Based on this review we conclude that DBL projects consist of open-ended, hands-on, authentic and multidisciplinary design tasks resembling the community of engineering professionals. Teachers facilitate both the process of gaining domain-specific knowledge and the thinking activities relevant to propose innovative solutions. Teachers scaffold students in the development from novice to expert engineers. Assessment is characterized by formative and summative of both individual and team products and processes and by the use of a variety of assessment instruments. Finally, the social context of DBL projects includes peer-to-peer collaboration in which students work in teams. The implications of these findings for further research on DBL in higher engineering education are discussed.  相似文献

In recent years, Singapore has increased its national emphasis on technology and engineering in early childhood education. Their newest initiative, the Playmaker Programme, has focused on teaching robotics and coding in preschool settings. Robotics offers a playful and collaborative way for children to engage with foundational technology and engineering concepts during their formative early childhood years. This study looks at a sample of preschool children (N = 98) from five early childhood centers in Singapore who completed a 7-week STEAM (Science, Technology, Engineering, Arts, and Mathematics) KIBO robotics curriculum in their classrooms called, “Dances from Around the World.” KIBO is a newly developed robotics kit that teaches both engineering and programming. KIBO’s actions are programmed using tangible programming blocks—no screen-time required. Children’s knowledge of programming concepts were assessed upon completion of the curriculum using the Solve-Its assessment. Results indicate that children were highly successful at mastering foundational programming concepts. Additionally, teachers were successful at promoting a collaborative and creative environment, but less successful at finding ways to engage with the greater school community through robotics. This research study was part of a large country-wide initiative to increase the use of developmentally appropriate engineering tools in early childhood settings. Implications for the design of technology, curriculum, and other resources are addressed.  相似文献

The world of technical education is moving towards an information collapse. This situation entails an aggravation of the contradiction between the desire to deliver more information to engineering students and the limitation imposed by the actual time that can be devoted to this activity. This, in turn, results in extensive competition between the subjects being taught and the consequent downgrading of certain areas. The second-grade subjects, such as drawing, subjects providing empirical knowledge, and the teaching of ideas about how things work are being pushed into the background by modern, updated, computer-aided and computer-serving subjects. The negative results of this competition in terms of teaching time and the better use computerized technology education are considered in this paper.  相似文献

This article describes a joint project conducted from 1991 until 1993 by the Japanese National Institute of Science and Technology Policy (NISTEP) and the German Fraunhofer institute for Systems and Innovation Research (ISI). Some first outcomes, and different alternatives on how to use the data for trend interpretation and priority setting, are described.
The Japanese Delphi survey is conducted every five years and was first undertaken in 1971. In 1992, NISTEP and ISI agreed on a joint project. About 3000 Japanese experts were asked to answer more than 1000 questions based on 16 different technological areas. With financial aid from the Federal German Ministry of Research and Technology (BMFT) the Japanese fifth Delphi survey was replicated in Germany. The Japanese questions were translated and more than 1000 German experts responded to the questionnaires and judged the possible technological development within the next 20 to 30 years. The aim of this joint project is to compare the Japanese and the German answers in order to analyse possible differences and to understand the cultural influences on technology assessment.  相似文献

Technological innovation has become a major source of farmer co-operatives’ competitive advantage, however empirical research on co-operatives innovation in a developing country context is rare. We adopt an ethnographic case study method collecting data from 32 co-operatives managers of four exemplar co-operative cases and agricultural experts in China and collected much archival data. In addition, a Delphi study was conducted to collect data on the innovation performance. Based on the distinctive characteristics of co-operatives, we found that first knowledge spillovers and technology acquisition modes are two constructs which best capture the dynamic of technological innovation in co-operatives and develop a typology based on them. Second, grassroots and social innovation in a Chinese co-operative context have their own characters and indeed a hybrid of capitalism (e.g., agribusiness) and New Rural Re-structuring principles (i.e., similar to ICA ones). Third and finally, we provide detailed agro-food policy implications for each of the four types of co-op innovation. The results of the research may be learned by co-ops and policy makers in other developing economies who face similar challenges as in China.  相似文献

Concept mapping provides a means for teachers and pupils to represent their understanding of an area of knowledge. It has been used as a planning tool by teachers to identify a framework of specific concepts and their propositions within a topic, as an assessment tool and as a means of collaborative sharing of knowledge. Information from two primary schools would also suggest that it can be used as a means of evaluating a school programme of primary technology. Research into people's perceptions and attitudes to technology indicated that there were a number of concepts and propositions associated with this field of study. A variety of groups of people including primary children were asked to describe what they understood to be technology and this information was constructed into a concept map format. The two schools described in the study had different programmes to deliver technology within the curriculum area of environmental studies. The first school had a planned programme of technology which was taught by the head teacher of the school. The second school had technology taught by class teachers, running as a thread throughout the environmental studies programme. In the first case the children knew when they were engaged in a technological task whereas in the second case the technology was implicit and the children were not necessarily aware of any specific subject area. The children's perceptions of technology and their attitudes towards it were analysed with reference to the constructed concept map. In the school where there were specifically programmed technological tasks, the children indicated that their understandings of technology were focused towards the design process; they identified technology as designing, making, problem solving and generating ideas. In relation to the Scottish curriculum their knowledge was concentrated in the area of the outcome entitled 'Understanding and Using the Design Process'. Children in the second school indicated that their understanding of technology was related to objects including computers and new inventions. This demonstrated that their ideas were mostly linked to the outcome entitled 'Understanding and Using Technology in Society'. It can be argued that in order to have a comprehensive understanding of technology the children should have knowledge and understanding of both outcomes. In the light of the results the head teachers of the respective schools decided to look more closely at their programmes in order to find out what modifications might be made. The head teacher of the first school decided to question the children more closely because he was aware of some attitudinal difference between the boys and the girls. He has now decided to do some further research in his school to see what changes need to be made. The head teacher of the second school is about to embark on a complete review of her school technology programme. The results of the research would suggest that concept mapping in the suggested form is a possible tool for evaluation of primary school technology prorammes. However this was only a small case study and further research would have to be done to provide more substantial evidence.  相似文献

We explore the role and relevance of resource scarcity in product innovation. The literature tends to assume that the development of new products requires resource sufficiency for the process to be conducted systematically. But we are also taught that necessity is the mother of invention and that resource scarcity may be a trigger of innovation in adverse contexts. In this discussion, we organize the literature on product innovation in resource‐poor contexts in three streams. The paper contributes to a finer‐grained understanding of the role of scarcity in product innovation and suggests that creative approaches to scarcity may contribute to knowledge enrichment of product innovation theory and practice.  相似文献

STEM-oriented engineering design practice has become recognized increasingly by technology education professionals in Taiwan. This study sought to examine the effectiveness of the application of an integrative STEM approach within engineering design practices in high school technology education in Taiwan. A quasi-experimental study was conducted to investigate the respective learning performance of students studying a STEM engineering module compared to students studying the technology education module. The student performances for conceptual knowledge, higher-order thinking skills and engineering design project were assessed. The data were analyzed using quantitative (t test, ANOVA, ANCOVA, correlation analysis) approaches. The findings showed that the participants in the STEM engineering module outperformed significantly the participants studying the technology education module in the areas of conceptual knowledge, higher-order thinking skills, and the design project activity. A further analysis showed that the key differences in the application of design practice between the two groups were (a) their respective problem prediction and (b) their analysis capabilities. The results supported the positive effect of the use of an integrative STEM approach in high school technology education in Taiwan.  相似文献

Spatial ability has been confirmed to be of particular importance for successful engineering graphics education and to be a component of human intelligence that can be improved through instruction and training. Consequently, the creation and communication by means of graphics demand careful development of spatial skills provided by the balanced curricula based on the research results in multi disciplinary area. The approach to engineering graphics education had been transformed to meet spatial skills improvement even before significant and fast changes arose from the development of computer technology enabling the engineer powerful tools and techniques. The correlation and interference between new technologies widely introduced in engineering graphics education and spatial ability/skills, have initiated new studies to establish the basis of holistic engineering graphics education. This paper presents the overview of some efforts and possible answers resulting from intensive research into spatial ability and skills and their implementation in the conception of graphics education in engineering environment.  相似文献
