We explore the relationship between a firm's organization and its ability to face a radical technological change. We suggest that, during such a change, the presence of both in‐house upstream knowledge and downstream market linkages, within a firm's boundary, has its advantages. We test our predictions in the context of the robotics industry where manufacturers of mechanically controlled “brawny” robots, which were valued mainly for their payload capacity, faced the advent of electrically controlled “brainy” robots that emphasized accuracy and repeatability. We find that “preadapted” firms—the ones with prior relevant technological knowledge and with access to internal users of “brainy” robots—were the innovation leaders in the emerging new technology but were laggards in the old technology.

This paper discusses a comparative study of the effects of using a humanoid robot for introducing students to personal robotics. Even if a humanoid robot is one of the more complicated types of robots, comprehension was not an issue. The study highlighted the importance of using real hardware for teaching such complex subjects as opposed to relatively cheap simulation environments. While the field of robotics is still in its infancy it benefits from a “wow” effect that can be utilized to positively influence the education of new specialists in this field. This comparative study, done at the Polytechnic University of Bucharest, highlights the educational benefits of this idea. Two groups of students took part on a completely volunteer basis in an “introduction to personal robotics” workshop. While one group only worked with simulators on computers, the other group was also given access to real robots in addition to the simulators. This allowed them to test their programs on a real platform and tweak them to compensate for differences between the virtual world and the real world. This second group had consistently and considerably better results than the first group.  相似文献

Building a robot from scratch in an educational context can be a challenging prospect. While a multitude of projects exist that simplify the electronics and software aspects of a robot, the same cannot be said for construction systems for robotics. In this paper, we present our efforts to create a low-cost do-it-yourself construction system for small robots. We have created three different construction systems (laser-cut screw connectors, printed friction-fit connectors, and printed hybrid connectors) using small aluminium T-slot extrusions, based on prior work done by Industrial Design college students. Eighty-six secondary school students and 35 teachers tested these three systems during a five-day robotics contest where they had to build firefighting robots. Follow-up questionnaires and an expert evaluation were used to measure the usability, affective appraisal and functionality of the three systems in order to determine which system should serve as a basis for further design iterations. Overall, a clear preference was shown for the hybrid system, which relies on its interlocking shape as well as on a screw connection to create robot frames that are both quick to construct and very rigid once assembled. We believe our work represents a solid first step toward an inexpensive, “hackable” construction system for educational robotics.  相似文献

This article is a part of a research project aimed to find out how different background variables are related to learning outcomes in school subject Sloyd as found in the national evaluation of the Finnish National Board of Education. Results from this larger research project were previously published in this journal, where pupils’ readiness for Self-Regulated Learning were reported. Since then, pupils’ experiences of classroom techniques, attitudes towards the subject, leisure time interests and learning within the two domains of the subject (Technical Domain and Textile Domain, as the subject is usually divided in Finland) have been studied and results have been published in different journals. In this article, a new Structural Equation Model concludes the previous results. The new model highlights two paths of how the use of different learning orientations can predict successful learning outcomes. These paths can be followed using two pedagogical models: the Exploratory Production Approach and the Domain Specific Approach. Experiencing Learner-Centred Learning predicts positive attitudes and success in Exploratory Production activities. Experiencing Collaborative Learning predicts success in domain specific learning outcomes. Success in Exploratory Production predicts successful learning outcomes in both domains. The conclusion is that regulatory knowledge, “why”, is related to production activities and it is processed prior to domain specific knowledge, “what” and “how”. To develop the subject and pedagogy for schools and teacher training, it is not important to follow an approach defined by the domains (technical or textile). It is more important to teach pupils how to manage in the modern technological world and to understand why they need to be able to improve their life-world through Exploratory Production activities.  相似文献

This paper presents a study about learning and the problem solving process identified among junior high school pupils participating in robotics projects in the Lego Mindstorm environment. The research was guided by the following questions: (1) How do pupils come up with inventive solutions to problems in the context of robotics activities? (2) What type of knowledge pupils address in working on robotics projects? and (3) How do pupils regard or exploit informal instruction of concepts in science, technology and problem solving within a project-based program? Data collection was made through observations in the class, interviews with the pupils, observations of the artifacts the pupils had constructed, and analyses of their reflections on each project. The study revealed that the pupils had often come up with inventive solutions to problems they tackled by intuitively using diverse kinds of heuristic searches. However, they encountered difficulties in reflecting on the problem solving process they had used. In robotics projects, the pupils deal primarily with qualitative knowledge, namely, the ability to identify specific phenomena in a system or factors that affect system performance. The study also showed that pupils are likely to benefit from implementing informal instruction on concepts in science, technology and problem solving into a project-based program. This type of instruction should take place in the context of pupils’ work on their projects, and adopt a qualitative approach rather than try to communicate in the class procedural knowledge learned by rote.  相似文献

Growing popularity of robotics education motivates developing its didactics and studying it in teacher training programs. This paper presents a study conducted in the Department of Education in Technology and Science, Technion, in which university students and school pupils cope with robotics challenges of designing, building and operating computer-controlled mechanisms. The university students were involved in developing robot prototypes and related instructional materials, and assisted in teaching robotics and guiding projects to middle school and high school pupils. The study focused on behaviors of the two groups of learners and aimed to elicit and analyze typical characteristics of learning in the developed robotics environment. We collected qualitative data on learning through robot design and experimentation activities and, by means of the ground theory method, elicited and analyzed typical behavioral characteristics of students’ and pupils’ learning: self-confidence, help, collaboration, interest, seriousness, self-dependence, learning effort, responsibility, coping with learning pressure, learning through observation, and perseverance. As found, the behavior characteristics evolve in the course of robotics studies and their evolution can give indication on the development of the desired competences.  相似文献

Technological systems are included as a component of national technology curricula and standards for primary and secondary education as well as corresponding teacher education around the world. Little is known, however, of how pupils, students, and teachers conceive of technological systems. In this article we report on a study investigating Swedish technology student teachers’ conceptions of technological systems. The following research question is posed: How do Swedish technology student teachers conceive of technological systems? Data was collected through in-depth qualitative surveys with 26 Swedish technology student teachers. The data was analysed using a hermeneutic method, aided by a theoretical synthesis of established system theories (system significants). The main results of the study are that the technology student teachers expressed diverse conceptions of technological systems, but that on average almost half of them provided answers that were considered as undefined. The parts of the systems that the students understood were mostly the visible parts, either components, devices, or products such as buttons, power lines, hydroelectric plants, or the interface with the software inside a mobile phone. However, the ‘invisible’ or abstract aspects of the technological systems, such as flows of information, energy or matter, or control operations were difficult to understand for the majority of the students. The flow of information was particularly challenging in this regard. The students could identify the input and often the output of the systems, that is, what systems or components do, but the processes that take place within the systems were elusive. Comparing between technological systems also proved difficult for many students. The role of humans was considered important but it was mostly humans as users not as actors on a more systemic level, for example, as system owners, innovators, or politicians. This study confirms previous research in that the students had a basic understanding of structure, input and output of a technological system. Thus, the adult students in this study did not seem to have better understanding of technological systems than school pupils and teachers in previous studies, although this is in line with previous investigations on the general system thinking capabilities of children and adults. The most important implication of this study is that students need to be trained in systems thinking, particularly regarding how components work and connect to each other, flows (especially of information), system dependency, and the human role in technological systems.  相似文献

The purpose of the study reported here was to investigate the use of a design-without-make unit as part of the design and technology curriculum with pupils aged 14. Three research questions drove the study: (a) What sort of designing do pupils do when they work collaboratively to design without having to make what they have designed? (b) What is the teachers’ attitude to design-without-make? (c) What is the pupils’ attitude to design-without-make? The study is a small pilot and data were collected using semi-structured interviews with a class teacher and two pupils and detailed scrutiny of five pupils’ design ideas developed during 6 lessons towards the end of an 18 lessons teaching sequence. Findings indicate that the teacher and pupils in this study responded favourably to design-without-make. The pupils’ designing was highly iterative, creative, involved making a wide range of design decisions and revealed understanding of technological concepts.  相似文献

In the context of the evolving Internet, a balance between technological advances and meaning change is crucial to develop innovative and breakthrough “connected electronics” that enable the Internet of Things. Designers and technologists are key enablers of this process respectively, ensuring adequate users’ needs and technology development, inside the evolving context of social environment and human relations. Smart electronic product design must be a truly interdisciplinary process, in which technologists are aware of how much their decisions impact the user-product relationship and designers understand the full potential and associated limitations of technology involved. Shared knowledge and communication are essential in this scenario, but, due to their technological limitations, designers are often excluded from high-level decision processes. In this paper, we address the design of constructivist tools and associated strategy to enhance the technological literacy of designers, as a strong foundation for knowledge-based dialogue between these realms. We demonstrate its effectiveness in a long-term multidisciplinary Project-Based Learning application with Design and Electronics students. We present the cases from 2 years’ experimentation (with the first year as control group) that demonstrate improvement in the quality of teamwork; in learning results; improved performance of the students reflected in the quality of the projects developed; and positive teachers’ and students’ evaluations. We conclude that the use of the proposed tool not only provides the designer an active voice in the process of designing smart electronics, but also promotes an effective common language between these two worlds.  相似文献

In recent years there has been an increasing focus on the missing “T” of technology and “E” of engineering in early childhood STEM (science, technology, engineering, mathematics) curricula. Robotics offers a playful and tangible way for children to engage with both T and E concepts during their foundational early childhood years. This study looks at N = 60 children in pre-kindergarten through second grade who completed an 8-week robotics curriculum in their classrooms using the KIWI robotics kit combined with a tangible programming language. Children were assessed on their knowledge of foundational robotics and programming concepts upon completion of the curriculum. Results show that beginning in pre-kindergarten, children were able to master basic robotics and programming skills, while the older children were able to master increasingly complex concepts using the same robotics kit in the same amount of time. Implications for developmentally appropriate design of technology, as well as structure and pace of robotics curricula for young children are addressed.  相似文献

The need for a new literacy that will allow for meaningful participation in the rapidly evolving field of nanotechnology is very critical to national development. This need is important for nanotechnology to achieve its full potential. This paper describes and analyzes some contemporary philosophical interpretations of the concept of technological literacy. The paper then focuses on some of the metaphysical assumptions underpinning the techno-scientific literacy framework; and theories governing public understanding of science and technology, as the basis to propose a new technological literacy framework suitable in the era of nanotechnology. A case is made that the new technological literacy framework proposed is a suitable and essential pedagogic endeavour which should be seen as yielding a perspective through which meaning may be infused into the importance of nanotechnology development–a perspective as essential to the informed lay person as it is to the truly literate technologist. The paper concludes by analyzing the implications of the proposed epistemological framework on nanotechnology workforce development and makes recommendations based on this new framework to achieve a ‘nanoliterate’ society.  相似文献

In this article, an instrument for assessing upper secondary school students’ levels of technological literacy is presented. The items making up the instrument emerged from a previous study that employed a phenomenographic research approach to explore students’ conceptions of technology in terms of their understanding of the nature of technology and their interaction with technological artefacts. The instrument was validated through administration to 1,245 students on completion of their 12 years of formal schooling. A factor analysis was conducted on the data and Cronbach alpha reliability co-efficients determined. The results show that a five-dimension factor structure (namely, artefact, process, direction/instruction, tinkering, and engagement) strongly supported the dimensions as developed during the original phenomenographic study. The Cronbach alpha reliability co-efficient of each dimension was satisfactory. Based on these findings, the instrument has been shown to be valid and reliable and can be used with confidence.  相似文献

Technological literacy defines a competitive vision for technology education. Working together with competitive supremacy, technological literacy shapes the actions of technology educators. Rationalised by the dictates of industry, technological literacy was constructed as a product of the marketplace. There are many models that visualise different dimensions of technological literacy, but clear empirical evidence on how these interact is still lacking. A measurement method that comprehensively evaluates technological literacy is missing. Insights into the stem structure and interaction of technological literacy dimensions could be useful for technology education curriculum design and its implementation. In this study, the multifaceted nature of technological literacy was measured using a new assessment method, and dimensions of secondary school students’ technological literacy were empirically investigated. A total of 403 students participated in the quasi-experimental research design. The treatment group consisted of 121 students taught optional subjects relating to technology education. The control group consisted of 282 students. Results from variance analysis showed that optional technology subjects enhance technological literacy, especially students’ technological capacity where a large effect size (η 2  = 0.14) was noted. Results from a path analysis revealed critical thinking and decision-making as the most important dimensions of technological literacy while the predictor of active participation in out-of-school technical activities and technology homework was a key independent influencing factor. A large effect size (R 2  = 0.4) for career path orientation predictors was detected. Technological capacity was revealed as a decisive predictor for a career path in vocational education and technical high school.  相似文献

This paper is based on work carried out as part of a research study into the professional practices of secondary design and technology teachers in England. It focused on fostering creativity or teaching for creativity as defined by the Robinson Report (1999, All our futures: creativity, culture and education. London: Department for Education and Employment (DfEE)) for pupils aged 11–14 years. The overall research question that drove this study was “to what extent can teachers influence the creativity of pupils aged 11–14 years in design and technology lessons?” The paper provides the basis used to generate a unique theoretical three-feature model or framework that can be used to explore creativity within an educational context.The findings of three investigations in the study are presented in this paper. The first and second investigations looked at what could be learnt from the professional practices of art and design and design and technology teachers and the views of four ‘expert’ teachers known for their ability to develop the creative potential of their pupils. The data is discussed under emerging themes and it is used to inform specific criteria in the evolving theoretical three-feature model for creativity. The model is then used to analyse the data from the third classroom based investigation and the findings are discussed under the emerging themes to help identify the issues related to fostering creativity within the design and technology classroom.This paper discusses the implications of the research for classroom practice and suggests that, as creativity is a complex, multi-faceted concept and process, the theoretical three-feature model and related criteria evolved in the study provides a sound framework to explore creativity within an educational context. As a tool it helps identify examples of good practice and highlight areas that require further attention by teachers aiming to foster their pupils’ creativity. It is suggested that design and technology teachers have lessons to learn from the practices of their art and design colleagues and ‘expert’ design and technology teachers. It is concluded that there is a need for greater understanding by teachers of their implicit theories regarding teaching, learning and creativity. A wider use could be made of the breadth of strategies outlined by the ‘expert’ teachers. This would help address the weakness identified in the school based study and strengthen classroom practice when teaching for creativity.  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

This paper contributes to the current debate about the “knowledge sharing-protecting” tension in R&D collaborations by introducing a new angle for analyzing this paradox. Considering the role of internal knowledge sources of the firm, the paper introduces and empirically analyses the interplay between three knowledge governance mechanisms (selective, contingent, and orchestrated openness) and the different technological fields of the firm (core, related non-core, and distant non-core technologies). Based on a unique first-hand large-scale project-level dataset from a Global 100 firm across a 10-year span, this research finds that R&D collaborations selectively conducted in firm’s related non-core technological fields promise the best innovation performance. Further, by orchestrating its projects across core and non-core technological fields in the same knowledge portfolio, the firm can leverage a network of inter-connected projects when collaborating with external partners. As such, the firm can strategically “distribute” collaboration risks across multiple projects, while optimize its access to external knowledge that it intends to get. Finally, contrary to the common assumption, this study does not find any discriminating factors against market-based partners in their contribution to innovation in both core and non-core technologies.  相似文献

Should humans work? A simple question at a time when the advent of AI, automation and robotics claims a privileged position in the future of work. The question is perplexing and confusing however once we enquire into the meaning of technology and work as such: some claim that human jobs and well-being might be threatened by technological advances while others predict an increase in high skilled demand.In short, we claim that standard debates obfuscate the question. That is, while animating the debate, standard arguments are instrumental to avoiding confrontation with the fundamental relation between humans, technology and work, namely, our position regarding what to do with technology and work, i.e. humans are “absent” in an “advancing” environment. We propose that focusing debates on the advantages and disadvantages of the development of advanced technology with the potential to do any human task does not necessarily clarify the situation, but rather unveils the obscurity of our relationship with technology by illuminating the lack of clarification.  相似文献
