This study presents the case of development and evaluation of a STEM-oriented 30-h robotics course for junior high school students (n = 32). Class activities were designed according to the P3 Task Taxonomy, which included: (1) practice—basic closed-ended tasks and exercises; (2) problem solving—small-scale open-ended assignments in which the learner can choose the solution method or arrive at different answers; and (3) project-based learning—open-ended challenging tasks. The research aimed at exploring students’ working patterns, achievements in learning the course, and the impact of this experience on students’ motivation to learn STEM subjects. Evaluation tools included a final exam on factual, procedural and conceptual knowledge in the STEM subject learned in the course, class observations, interviews with the students, and administrating an attitude questionnaire before and after the course. Since the experimental class was quite heterogenic in regard to students’ prior learning achievements and motivation to learn, some of the students completed just the basic exercises, others coped well with the problem-solving tasks, and only a few took it upon themselves to carry out a complex project. However, all students showed high motivation to learn robotics and STEM subjects. In summary, robotics provides a very rich and attractive learning environment for STEM education. Yet, the realization of this potential depends largely on careful design of the course methodology and especially the students’ assignments in the class. One should recognize that often only some students are capable of learning a new subject on their own through project work, and these students also need to gain additional knowledge and skills before dealing with complex projects.  相似文献

Project-based learning (PBL) is a well-known method for imparting thinking competencies and creating flexible learning environments. Advancing low-achieving pupils is an on-going challenge for educational systems. Routing low-achievers into low-learning tracks creates a vicious circle. In order to extract pupils and their teachers from the on-going cycle of failure, and to promote pupils cognitively and emotionally, four steps were taken: defining significant goals for the pupils as well as for the teachers, changing the learning environment, carrying out original projects taking advantage of the pupils' special skills and abilities, and changing assessment methods for project-based learning activities in a computerized environment. This paper presents a continuous field research that has used qualitative and quantitative tools for exploring pupils' progress in the affective and the cognitive domains. The research tools were: Analysis of pupils' portfolios, observations of class activities, interviews with pupils, teachers and school management, achievements in the matriculation examinations, and assessment of pupils' projects. The findings indicate that scientific-technological PBL elevated pupils' motivation and self-image at all levels and achieved significant affective learning. The activities over three years are summarized and show an increase in the number of students achieving the college admittance requirements. Most of the low-achieving pupils succeeded with distinction in the same matriculation exams that the high-achievers did in the same school. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

The aim of this study is to explore critical design issues for educational robotics training camps and to describe how these factors should be implemented in the development of such camps. For this purpose, two robotics training camps were organized for elementary school students. The first camp had 30 children attendees, and the second had 22. As a research methodology, a multiple-case design approach was used. Interviews with children and instructors, observations, field notes, and camp evaluation forms were used as data collection methods. The data were analyzed by qualitative data analysis techniques and categorized into themes: instruction, group issues, competition, coaching, technical issues, challenges, and camp duration. Prominent findings indicate that instruction strategies for a robotics camp should be designed from simple to complex. The most effective and enjoyable part of the camps were the project studies, which should be highly encouraged. Robotics training camps should provide children a chance to practice what they have learned in school. Group size should allow for every child in the group to have tasks assigned at all times.  相似文献

Infusing creative thinking competence through the design process of authentic projects requires not only changing the teaching methods and learning environment, but also adopting new assessment methods, such as portfolio assessment. The participants in this study were 128 high school pupils who have studied MECHATRONICS from 10th to 12th grades (16–18 years old). By the end of 12th grade, the pupils had created 57 authentic projects. The intervention program had two parts: first, the pupils documented their project according to a creative design process that had been introduced to them. Second, the projects were assessed according to a creative thinking scale. This scale was designed to assist pupils in documenting the design process. It could be used as a guideline for teachers and pupils during the course of the project. The research examined pupils’ performance during project-based learning. The research tools included: observations of class activities, portfolio assessment, and external matriculation assessment. The findings show first that pupils learned to document their design process. Second, pupils’ projects demonstrated various levels of creative thinking skill. Evidences for high-level documentation of the projects were found in pupils’ portfolios. On the other hand, there is much to be learned about documenting teamwork and pupils’ reflection. This research could assist researchers and teachers who are interested in assessing engineering education outcomes.  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

The purpose of this paper is to address the simultaneous management of multiple business relationships and multiple projects in the marketing strategy of the project-based firm. The research question is: How can the essence and interdependencies between the portfolios of relationships and projects be conceptualized as the marketing strategy of a project-based firm? We address this question by constructing a framework including two portfolios of relationships and two portfolios of projects, and by discussing how these portfolios may be interrelated. Combining the approaches of relationship management in project marketing on the one hand and the management of project portfolios on the other contributes a novel viewpoint to project marketing.  相似文献

We have investigated collaborative problem solving in a teaching experiment, which was organised for 34 eighth-grade pupils in a control technology learning environment. The participating teacher was trained by us and pupils had available kits, interfaces and computers equipped with a novel icon oriented programming tool, Empirica Control. Pupil activities were video recorded and the analysis proceeded through writing video protocols, edited into episodes and then classified into categories. Categories were mainly derived empirically. In the analysis, we used concepts such as collaboration and problem solving, in accordance with social constructivism. The data showed that typical learning processes were collaborative (62% of all episodes) as well as dynamic problem-solving processes, in several stages. Pupils worked quite independently of the teacher, as they learned to use the programming tool autonomously in their technology projects. It appears, however, that more teacher support, such as introducing handbooks, planning tools and advanced programming skills, would have been an advantage. Some ideas about further development of study processes in modern learning environments are discussed. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

This study investigates what pupils aged 10–12 can learn from working with robots, assuming that understanding robotics is a sign of technological literacy. We conducted cognitive and conceptual analysis to develop a frame of reference for determining pupils’ understanding of robotics. Four perspectives were distinguished with increasing sophistication; “psychological”, “technological”, “function”, and “controlled system”. Using Lego® Mindstorms® NXT robots, as an example of a Direct Manipulation Environment, we developed and conducted a lesson plan to investigate pupils’ reasoning patterns. There is ample evidence that pupils have little difficulty in understanding that robots are man-made technological and functional artifacts. Pupils’ understanding of the controlled system concept, more specifically the complex sense-reason-act loop that is characteristic of robotics, can be fostered by means of problem solving tasks. The results are discussed with respect to pupils’ developing technological literacy and the possibilities for teaching and learning in primary education.  相似文献

There are many published models for the process of design or open-ended problem solving. Some of these are represented in diagrammatic form while others are implicit within the text of the publication. Where do these models come from? Upon what evidence are they based and how accurately do they describe the pupil designer? The idea that we should teach pupils a procedure for completing design and make tasks or a strategy for solving problems is an attractive one but is there only one procedure and is this easily transferred to a wide variety of tasks? This article examines the similarities in a variety of published models for the design or problem-solving process including those implicitly described in the development of the National Curriculum for Design and Technology in England and Wales. It finds a surprising consensus of opinion among authors but suggests that there is little research evidence to support their claims.  相似文献

Engineers commonly use rules, theories and models that lack scientific justification. Examples include rules of thumb based on experience, but also models based on obsolete science or folk theories. Centrifugal forces, heat and cold as substances, and sucking vacuum all belong to the latter group. These models contradict scientific knowledge, but are useful for prediction in limited contexts and they are used for this when convenient. Engineers’ work is a common prototype for the pupils’ work with product development and systematic problem solving during technology lessons. Therefore pupils should be allowed to use the engineers’ non-scientific models as well as scientific ones when doing design work in school technology. The acceptance of the non-scientific models for action guidance could be experienced as contradictory by pupils and teachers alike: a model that is allowed, or even encouraged in technology class is considered wrong when doing science. To account for this, different epistemological frameworks must be used in science and technology. Technology is first and foremost what leads to useful results, not about finding the truth or generally applicable laws. This could cause pedagogical problems, but also provide useful examples to explain the limitations of models, the relation between model and reality, and the differences between science and technology.  相似文献

Real issues of web design and development include many problem-solving tasks. There are, however, some inadequacies associated with the implementation of appropriate pedagogy for organised and structured instruction that supports the rational problem-solving paradigm. The purpose of this article is to report on a study for the design and implementation of an Instructional Web Design Programme (IWDP) with methodology-specific guidelines in an information systems design context. A second purpose is to discuss the pedagogy developed within the IWDP and its effects on promoting technological problem solving of learners in the project-based classroom. A qualitative, action-research approach was the basis for this study. The sample consisted of 17 learners at an institution of higher education. The researchers used a focus group interview, journals and essays to observe learners’ behaviour, to analyse their project designs and to assess their opinions and experiences with regard to the IWDP. An organised and structured instructional environment within the IWDP helped the teacher to promote technological problem solving. The teacher and learners acknowledged the components of the programme (for example, assessment criteria, range statements, performance indicators, pre-defined learner tasks and activities) in the project-based classroom. Practical and cognitive apprenticeship and experiential and situated learning were used to accommodate the problem-solving needs of learners. Learners indicated a need for a variety of tools and expert guidance in a peer-based collaborative learning environment.  相似文献

Research summary : The knowledge‐based view suggests that complex problems are best solved under hierarchical (within‐firm) governance. We examined why firms assumed to be in general alignment with this theory might nonetheless produce solutions of varying usefulness. We theorize that a firm's internal knowledge variety (IKV) is associated with its capacity to support cross‐domain knowledge flows during search, and its ability to identify and explore promising areas on the solution landscape. We further theorize that partner knowledge in familiar (unfamiliar) domains can offset specific weaknesses in searching rugged landscapes, inherent with low or high (moderate) IKV. We find support for these ideas in the context of drug discovery, extending KBV's focus on governance alignment to explain variation in problem‐solving effectiveness within hierarchy. Managerial summary : Firms that concentrate their inventive efforts in a few technological domains, but also dabble in several others, have problem‐solving advantages: they can better support knowledge transfer and recombination across domains. Firms that focus too narrowly or spread their inventive efforts thinly across many domains lose these advantages, but might compensate through alliance partnerships. Our study of drug discovery shows that while firms with very low or high knowledge variety tend to produce weaker solutions than firms in the moderate range, their inventive performance improves when alliance partners afford them access to additional knowledge in familiar domains. We explain how the combination of firm and partner knowledge enables firms to better identify, evaluate, and implement alternative solutions to complex problems.

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

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

While comprehensive, ongoing competitive intelligence systems generate valuable input for broad strategic decisions, they often fail to provide the specific actionable information needed by managers operating in a project-oriented environment. This paper proposes a project-based framework for competitive analysis. The framework was developed from field reseach involving 16 projects. A comparison of project-based and comprehensive competitive analysis systems is made to illustrate their differences. A case example from field research is utilized to illustrate concepts central to this approach and its practical utility. A set of guidelines regarding pitfalls to avoid in project-based competitive analysis is presented.  相似文献

In a contest featuring hands-on projects, college students were required to design a simple crawling worm using planning, self-monitoring and self-evaluation processes to solve contradictive problems. To enhance the efficiency of problem solving, one needs to practice meta-cognition based on an application of related scientific concepts. The objective of this study, then, was to analyze the physics concepts employed by the students as they completed a hands-on project named “Crawling Worm,” during which they had to overcome problems encountered by the requirements of their design as well as those brought on by competition. Based on the analysis of the participants’ working portfolios and on reviews and interviews by engineering professors, the results of this study show that the crawling worm design competition encouraged the practice of problem solving, and it facilitated the learning of physics concepts such as friction, torque, four bar link, material properties, and so on.  相似文献

Previous research by one of the authors showed that novice designers do not use sketching as a way to generate, develop and communicate design proposals, but move immediately to three-dimensional modelling. Neither do they generate multiple solutions. The follow-up study described here addressed the questions: Does teaching two-dimensional modelling enable Grade 7 pupils to better express their ideas and organize their thoughts? What role does discussion play in pupils' attempts to generate a design proposal? Does the use of contextualising items make a difference to pupils' success with designing? Eight Grade 7 pupils were drawn from each of two classes. One class had received instruction in sketching; the other served as a control group. Each group of eight pupils was divided into single-sex dyads. The eight dyads were videotaped while producing a solution to a common design brief. Analysis of the data has provided insights into the effects of instruction on the proposals produced by pupils. Additionally, their ability to generate, develop and communicate design ideas is enhanced by both the dynamic relationship between pupils' talk and 3D modelling and the way the task is contextualised. This revised version was published online in July 2006 with corrections to the Cover Date.  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
