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

Several authors insist on the importance of students’ acquisition of spatial abilities and visualization in order to have academic success in areas such as science, technology or engineering. This paper proposes to discuss and analyse the use of educational robotics to develop spatial abilities in 12 year old students. First of all, a course to introduce robotics to 6th grade primary school students was designed. The key intention was to prepare practical and motivating sessions in order to foster the students’ involvement in hands-on learning. Hence, during the sessions of the course, challenges were provided for the students, in order to develop their capabilities as proficient problem solvers. The teacher assisted and guided the students, and the students were encouraged to solve the problems by themselves, working in 3-members teams. The main goal of this paper is to discuss and analyse the potential usefulness of educational robotics to develop spatial abilities. To carry out the analysis, students were randomly divided into an experimental group (EG), which participated in the robotics course, and a control group (CG), which did not take part in the robotics course. The extensive existing literature for spatial ability evaluation was analysed and reviewed and a pre-test and a post-test were prepared for use in the research study. Initially, the spatial ability of both EG and CG students was assessed with the pre-test. Then, after finishing the robotics course, the same sets of students were tested with the post-test. An extensive analysis of the results is provided in the paper. Results show that the positive change in spatial ability of the participants in the robotics course (EG) was greater than change evident in the students who did not join the course (CG). The improvement was statistically significant. The results also show that the overall performance of the students depends on the instruments used to evaluate their spatial abilities. Hence, this study manifests clearly the importance of the selection of those instruments.  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

This article is a part of a research project aimed to find out how different background variables are related to learning outcomes in technology education related to the school subject Sloyd (craft). The research question of this article is: “How are ninth grade students’ attitudes towards the subject related to their learning outcomes?” The empirical data (n = 4792) was collected by stratified sampling from 152 secondary schools as a part of the Finnish National Board of Education (FNBE) assessment. A shortened Finnish version of the Fennema–Sherman attitude test was carried out in a narrowed sample (n = 1548). The three attitude factors for learners were ‘Liking Sloyd as a school subject’, ‘Experiencing Utility in Sloyd’ and ‘Self-concept in Sloyd’. Structural equation modelling revealed that ‘Experiencing Utility’ predicts learning outcomes while ‘Liking’ and ‘Self-concept’ were interveners. The results suggest more learner-centred pedagogics for developing technology education.  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

The subject of design and technology was introduced to the curriculum for high schools in China 10 years ago. However, the teaching and learning of this subject have become difficult for both teachers and students because there is a lack of qualified teachers with design background to deliver this subject in a way to stimulate the learning interests of the students. This paper presents a research that is aimed at improving this situation by integrating the teaching and learning of design and technology within a computational environment as part of social networks sites. The purpose is to enable the collaboration among the students and interaction between teachers and students. In this research, a series of investigations were conducted, by following through several taught subjects in design and technology in prominent high schools in China. Based on these investigations, a theoretical framework for web-based design learning and teaching system in the style of social networking is developed, implemented and tested, emphasizing three features of design: innovation, collaboration, and interaction. This framework has been tested among high school students and teachers in a high school in Nanjing. It identified and validated necessary techniques and design features required to make an education-related social networking site effective and affective for the students and teachers. The results of this research indicated that social networking sites have significantly positive values in design education, especially for the collaboration and interaction on the subject of design and technology.  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

Inasmuch as design is a central activity in K-12 engineering education, understanding the students’ motivation during engaging in engineering design activities will help educators to develop and evaluate strategies for engineering design challenges, and improve curriculum. The objective of this study is to better understand the relationship between students’ interest and expectancy for success while engaged in two design activities in grades 9–12. The primary difference between the two activities was the strategy used to solve the design problems from a predictive analysis and a creative approach. Constructs of motivation for students’ interest include task value (TV) and intrinsic goal orientation (IGO) and extrinsic goal orientation (EGO). Expectancy for success includes control of learning beliefs and self-efficacy for learning and performance. In this study, students (n = 31) from three high schools that implement the Project Lead the Way curriculum in three states in the US participated in the study. Immediately after completing their design projects, each student was asked to complete a modified version of the Motivated Strategies for Learning Questionnaire survey instrument which evaluates their interest and expectancy for success. The results show that students were more intrinsically motivated to engage in a design activity that involves a predictive analysis than a creative approach. No significant correlation was found between students’ expectancy for success and EGO in design tasks that utilized either predictive analysis or creative approach. The study also found that TV and IGO were good predictors for students’ expectancy for success. Demographic information associated with students’ motivation in the design activities is also presented.  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 study was conducted with the aim of creating a new introductory course emphasizing the development of technological literacy for elementary school pre-service teachers. This study also aimed to investigate elementary school pre-service teachers’ attitudinal transition toward elementary school technology education (ESTE) and its implementation. An introductory ESTE program within Practical Arts Education was developed through a procedure consisting of preparation, development, and improvement. The program was implemented among 127 elementary school pre-service teachers for 7 weeks in South Korea. The learning contents based on the ESTE research and national curriculum included (1) technology learning units in the Practical Arts textbooks, (2) technology and invention, (3) drawing and design, (4) wood products, (5) basic electricity and electronics, and (6) integrative science, technology, engineering, and mathematics/science, technology, engineering, arts, and mathematics education. These contents were delivered via an instructor’s lecture, hands-on activities on technological design, and cooperative learning. A pre- and post-test on the study participants’ attitudes toward ESTE and on their knowledge, competency, and anxiety in relation to the six learning contents were conducted. The research results indicated a stable improvement in the study participants’ attitudes toward ESTE, their level of knowledge about ESTE, and their competency to teach ESTE. The developed program also decreased their anxiety in relation to teaching ESTE. The study findings may provide useful insights into the professional development of elementary school teachers in connection with ESTE, and into the implementation of technology education in the elementary school setting.  相似文献

As cultural, social, political and economic changes take place, the secondary or high school curriculum should reflect and respond to changing needs and aspirations of students. Technology Education has been proactive in this arena as it has transformed over the decades to meet ever-changing societal needs. The most recent change to the discipline has been to add engineering and, as a result, adopting a new name and curriculum-Engineering and Technology Education. The added component and name change in Technology Education is causing discussions about what the new direction means, what professional preparation changes will be incurred, and what work graduating students will be prepared to do. In light of these changes, this study investigated perceptions of high school students in the United States of America about engineering and technology courses they take. To investigate whether students’ perceptions are in accord with current changes in Engineering and Technology Education, 316 students enrolled in engineering and technology courses in Georgia schools that have an affiliation with the Georgia Engineering and Technology Education Association (GETEA) were surveyed. According to data analyses, students’ perceptions can be divided into two factors. Educational Value of Course (factor 1) was extracted from statements measuring the degree to which the courses prepare students for employment and provide them with information regarding future employment. Personal Relevance of Course (factor 2) was derived from statements measuring students’ perceptions about links between engineering and technology education and their personal lives. Such findings suggest these students valued their engineering and technology courses, planned to continue their education, made good grades, and had varied types of career expectations for jobs such as design engineers and architects.  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

A diverse group of 20 high school students from four states in the US were individually provided with an engineering design challenge. Students chosen were in capstone engineering courses and had taken multiple engineering courses. As students considered the problem and developed a solution, observational data were recorded and artifacts collected. Quantitative methods were used to identify how students allocated their time across different types of modeling. Qualitative methods were used to review data from three students who spent substantial time engaged in graphical and two kinds of mathematical modeling. These students were profiled and their patterns of modeling are represented visually and described in context. Much of the modeling done by these 20 students was graphical in nature. Few students informed their thinking with mathematical representations, yet predictive mathematical modeling is essential to engineering design. Implications for the classroom include encouraging students to transfer understanding of science and mathematics into technology and engineering contexts through modeling.  相似文献

This paper aims to investigate the predictive validity of learning styles on academic achievement and technological literacy (TL). For this purpose, secondary school students were recruited (n = 150). An empirical research design was followed where the TL test was used with a learning style inventory measuring learning orientation, processing information, thinking, perceiving information, physical and time learning preferences, and sociological, emotional, and environmental learning preferences. Student performance was measured with grade point average (GPA) and TL level. Results show that 69 and 65 % of the variance in GPA and TL, respectively, can be explained by learning style predictors. Responsible and visual learning styles are the best positive predictors of GPA, while a reflective learner is the best negative predictor. Self-motivated and global learners are the best positive predictors of TL, while the need for authority figures and a theorist learning orientation are the best negative predictors of TL. The practical implications are that secondary schools should collect learning style data before helping students accordingly to be successful and more technologically literate. Highly conforming, global, and visual theorists might be offered more challenging tasks and special commendations on their projects, whereas more reflective and kinaesthetic students could receive more unstructured instruction in a busy environment with learning objects that incorporate innovative experiences, personalised information, and many associations. Assimilators need more textual material, more criterion-referenced instructions to achieve higher-order thinking learning objectives, more time to complete activities or assignments, more abstract problems, and unconstrained design conditions to improve their TL.  相似文献

The focus of this paper is students’ design productions as they engaged in designing and making a windmill model to lift a given weight. This work is part of a project on the development of design and technology (D&;T) education units and its trials among Indian middle school students (Grade 6, age 11–14 years) in different socio-cultural settings. Since D&;T is not a part of the Indian school curriculum, the students had no earlier experience of design. Our trials included an exploratory phase followed by groups of students producing technical drawings and a plan for the making action (procedural map) before engaging in making the windmill model. The paper presents findings from a qualitative analysis of urban and rural students’ pencil and paper productions, complemented by observations from video recordings of the collaborative engagement of these naïve designers. Students used graphical symbols, analogical, spatial and functional reasoning in their design activities. Choice of materials and tools, the nature of exploratory sketches, variety in design and attentions to issues of stability showed differences between the urban and rural groups. Some potential implications of D&;T units for classroom learning have also been discussed.  相似文献

The paper reports on the trials of a Design and Technology (D&T) unit carried out in three different Indian contexts with a focus on collaborative learning. Both collaboration and technology education are not common to the Indian school system. As part of a larger project to introduce technology education, suitable for middle school girls and boys in urban and rural areas, three culturally appropriate and gender sensitive D&T units were developed. All the units were tried out with middle school students in different socio-cultural settings: two schools in urban areas (with different languages of teaching and learning) and one in a rural area. This paper presents details of a unit on puppetry which involved making a puppet and staging a puppet-show. Aspects of collaboration within and among groups were observed with respect to: roles played by the members, conflicts and their resolution, sharing of resources, communication and peer review among the students. The trials in the three clusters indicate the potential of this D&T unit to provide collaborative learning situations for the multicultural contexts of Indian classrooms.

Early childhood is a critical period for introducing girls to traditionally masculine fields of science and technology before more extreme gender stereotypes surface in later years. This study looks at the TangibleK Robotics Program in order to determine whether kindergarten boys and girls were equally successful in a series of building and programming tasks. The TangibleK Program consisted of a six lesson robotics and programming curriculum that was implemented in three different kindergarten classrooms (N = 53 students). Although previous research has found that males outperform females in robotics and programming related fields, it was hypothesized that the young age of participants and their limited cultural indoctrination regarding gender stereotypes would allow boys and girls to have equal success in this program. Although boys had a higher mean score than girls on more than half of the tasks, very few of these differences were statistically significant. Boys scored significantly higher than girls only in two areas: properly attaching robotic materials, and programming using Ifs. Overall, both boys and girls were able to successfully complete the program.  相似文献

This paper reports on research investigating six middle school teachers without engineering degrees as they taught an engineering unit on the engineering design process. Videotaped classroom sessions and teacher interviews were analyzed to understand the subject matter and pedagogical content knowledge the teachers used and developed as they introduced the eight steps of the engineering design process (from content standards for the state of Massachusetts, USA). The teachers demonstrated wide-ranging knowledge of the engineering design process, and this paper describes two of the steps the teachers showed a more sophisticated understanding—constructing a prototype and redesigning. Examples from the teachers illustrate strengths that can be built upon as well as some areas for further development.  相似文献

In this article we report assessment results from two studies in an ongoing design experiment intended to provide a single school system with a sequence of secondary school level (ages 14–18) computer technology courses. In our first study, we share data on students’ learning as a function of the required introductory course and their pre-course history of technological experience. In order to go beyond traditional assessments of learning we assessed two aspects of students’ “learning ecologies”: their use of a variety of learning resources and the extent to which they share their knowledge about technology with others. In our second study we present patterns of course taking by male and female students who have almost completed their secondary schooling. In addition, we share case studies of students who elected to take more technology classes and leveraged their course experiences for internships, further education, and jobs. The quantitative and qualitative data are consistent with our hypothesis that students would become more technologically fluent and that their learning ecologies would diversify as a result of their project-based experiences.  相似文献

Following initial educational enthusiasms for ‘Making’ technologies and the ‘Maker Movement’, increasing numbers of students are now using digital fabrication programs and equipment in school. Given the current lack of empirical research exploring the realities of Making as a school activity, this paper presents an in-depth auto/ethnographic account of 3D printing—currently, one of the most popular Maker technologies in schools. Investigating the case of an 8 week Year 9 design project, this paper seeks to broaden understandings of how 3D printing technologies and practices are shaping “what counts” as learning within contemporary school settings. In particular, this research focuses on the experiences of Making within a school context; what is learned through these experiences; and how the process of Making in school feels. This paper highlights three key issues that have been marginalised to date in discussions of Making in schools: (1) lack of pragmatic engagement, (2) affective labour of failing; and (3) mediated alienation.  相似文献
