The impact of problem-based learning strategies on STEM knowledge integration and attitudes: an exploratory study among female Taiwanese senior high school students

This study was designed to explore the effects of problem-based learning (PBL) strategies on the attitudes of female senior high school students toward integrated knowledge learning in science, technology, engineering, and mathematics (STEM). Content analysis and focus group methods were adopted as the research processes. Data and information about the STEM internet platform, an attitude scale and the contents of interviews were also collected for analysis. The subjects were 10th grade students at a girls’ senior high school who volunteered to organize teams for a Solar Electric Trolley Contest. A total of 40 students were grouped into 18 teams. The results of the study indicate: (1) that PBL strategies can be helpful in enhancing students’ attitudes toward STEM learning and the exploration of future career choices; (2) that the PBL teaching strategy helped to lead students step by step toward completing the contest’s mission and to experience the meaning of integrated STEM knowledge; (3) that not only that students can actively apply engineering and science knowledge, but also that students tend to gain more solid science and mathematics knowledge through STEM learning in PBL; and (4) that PBL can enhance students’ abilities and provide them experiences related to knowledge integration and application. Therefore, it is recommended that the curriculum at the girls’ senior high school include more content related to specialty subjects to enhance their technological capabilities. In addition, a learning mechanism should be offered to aid advisers or teachers in strengthening students’ integrated and systematic knowledge about STEM.     

The senior high school students’ learning behavioral model of STEM in PBL

The purpose of the study was to explore a learning behavioral model of project-based learning (PBL) for senior high school students in the context of STEM (science, technology, engineering, and mathematics). Using “audio speakers” as the project theme, a series of tasks were designed to be solved using STEM knowledge via an online platform and student group discussions. A total of 84 volunteer students from a senior high school and a vocational school in Pingtung, Taiwan, were divided into 21 groups. Text analysis and questionnaire survey were administered. Data sources were the participants’ information collected via the STEM online platform and the questionnaire survey regarding STEM in PBL. The findings of the study are as follows: (1) the learning behavioral model for STEM in PBL showed a positive influence on students’ behavior in the form of cognition and behavioral intentions. In addition, cognition and behavioral intentions were positively influenced by attitude. The overall model fit was positive and could effectively explain senior high school and vocational school students’ learning behavior as related to STEM in PBL; (2) according to the results of the analysis of STEM from the online platform, students displayed a positive attitude, attained integrated conceptual and procedural knowledge, and demonstrated active behavioral intentions through STEM in PBL. In addition, the students’ creative and organized project outcomes revealed the effects of their behavior.     

Students’ knowledge sources and knowledge sharing in the design studio—an exploratory study

Architectural design is a knowledge-intensive activity; however, students frequently lack sufficient knowledge when they practice design. Collaborative learning can supplement the students’ insufficient expertise. Successful collaborative learning relies on knowledge sharing between students. This implies that the peers are a considerable design knowledge source for the students. However, students are involved in grade competition. Students may not be willing to share because knowledge is a critical resource for students’ performance. The web technology has been used to facilitate knowledge exchange among students; nevertheless, the convenience of technology may tempt free riding behavior and impede the development of a knowledge sharing culture. The purpose of this exploratory study is to probe whether the peers and a web forum are the students’ primary knowledge source by investigating students’ knowledge sources during the design process. The results demonstrated that (1) studio-mates were a primary design knowledge source for the students, (2) the ill-defined nature of design problems may be the main contributing factor encouraging knowledge sharing behavior, (3) the shared web forum was not a primary knowledge source for the students and did not have a significant influence on the knowledge sharing culture, and (4) we can estimate the knowledge sharing culture in a design studio through investigating students’ knowledge sources. Furthermore, several additional findings and implications are elaborated.     

Effects of web-based versus classroom-based STEM learning environments on the development of collaborative problem-solving skills in junior high school students

Collaborative problem-solving skills are one of the key competencies required in the twenty-first century. In this study, researchers attempted to compare the effectiveness of web-based collaborative problem-solving systems (wCPSS) and classroom-based collaborative hands-on learning activities (cCHLA) in the development of collaborative problem-solving skills in junior high school students who were learning science, technology, engineering, and mathematics (STEM)-related subjects. A quasi-experimental, nonequivalent pretest–posttest control group design was employed, and 241 junior high school students were invited to participate in the study. According to the results, a wCPSS-supported environment with teacher guidance was found to be more effective than either a wCPSS-supported environment without teacher guidance or a cCHLA-facilitated environment in developing students’ collaborative problem-solving skills in STEM fields. The study suggested that a web-based collaborative problem-solving system with teacher guidance can be used in developing junior high students’ collaborative problem-solving skills in STEM education.     

DEPTH2: developing professional knowledge in D&T secondary initial teacher education

There are various aspects to teachers’ professional knowledge, some such as subject knowledge are more easy to articulate than others, for example knowing how to construct a scheme of work. Student teachers need to be able to understand the various aspects of teachers’ professional knowledge in order to be able to help themselves reflect on and develop these various aspects. This research builds on earlier work conducted with design and technology colleagues in a number of different countries and teacher training institutions (see Banks et al., International Journal of Technology and Design Education, 14, 141–157, 2004). Leach and Banks, together with other colleagues, developed a visual tool for discussing the aspects of professional knowledge that student teachers are required to develop and this formed the basis of this research (Leach and Banks, Investigating the developing ‘Teacher Professional Knowledge’ of student teachers, 1996). The research was carried out with a cohort of 1-year Post Graduate Certificate in Education (PGCE) students on a conventional face-to-face programme. There were 11 in the group with six male and five female and the majority were aged under 25; this is atypical of this course both for gender and age, but this constituted the 2004–2005 intake. There were three data collection points: September 2004, on their first day of their course; January 2005 following their first school placement and June 2005 at the end of the course. The findings indicate the students’ development across the PGCE course in each of the areas relating to knowledge of subject, pedagogy and school. In each area there is a growth in their knowledge and a development in the complexity of their understanding. The students’ knowledge developed from a generalised understanding to a more specific and sophisticated one. It is hoped to be able to continue this research during the induction year of each successful student.     

Characteristics of learning computer-controlled mechanisms by teachers and students in a common laboratory environment

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.     

A phenomenographic study of Greek primary school students’ representations concerning technology in daily life

The present research investigated and studied students’ representations about daily life technologies, in a prospect of studying technology in Greek primary education. In the research participated 60 Greek primary school students aged 9 to 12 years old. Research data were collected through semi-structured, personal, clinical-type interviews. Each interview investigated student’s conceptions and views about the following thematic areas: the concept of technology, daily life technologies, technological change, and the impact of technology use in everyday life. Data analysis revealed that the majority of students equated technology with modern tools and appliances, especially with computers, TV, mobile phones, satellites and other micro- and macro-technologies, whereas experience based technologies (de Vries, Technology education: Beyond the “technology is applied science” paradigm. J. Technol. Edu. 8 (1996), 7) have been hardly recognized by them as technology. Also students’ representations can be categorized either as technology-oriented representations, which focus on a collection of technical means without reference to humans, or as human-oriented representations, focused on technical means with substantial reference to human needs and activities. Depending on these types of representations, students seem to conceive differently the nature of the problems, which they recognize that the wide use of technology causes mainly to the environment and the responsibility of the user for these problems. Moreover, it seems that the concept of technological change is a quite difficult one for the students. In order to help students form adequate representations about daily life technology and technological change an appropriate teaching approach was designed on the basis of these students’ representations.     

A ‘Knowledge Trading Game’ for collaborative design learning in an architectural design studio

Knowledge-sharing and resource exchange are the key to the success of collaborative design learning. In an architectural design studio, design knowledge entails learning efforts that need to accumulate and recombine dispersed and complementary pieces of knowledge. In this research, firstly, ‘Knowledge Trading Game’ is proposed to be a way for promoting students’ design knowledge exchange, dissemination and refinement. Twelve students are randomly chosen as experimental participants. And secondly, ‘virtual value’ is used for students to trade their design knowledge. In this game, students buy others’ design knowledge to extend their design problem space; students decrease their design solution space through their sold design knowledge. Finally, ‘protocol analysis’ is adapted as the research methodology to examine the results of implementation. A positive outcome is identified that Knowledge Trading Game encourages collaborative design learning.     

Teacher Perceptions of Design and Technology: A Study of Disjunction between Policy and Practice

This study examines the curriculum directions being charted by a sample of county secondary school design and technology teachers in England and Wales. The purposes of design and technology are analysed, and the syllabuses and examinations used reviewed, together with how design folios are incorporated into teaching. In addition, teacher reports on student-teacher classroom performance, and student-teacher evaluations of their teaching practice experiences are analysed. It was found that teacher perceptions are highly pragmatic and technical, with the pupils‘ intended learning outcomes largely being defined instrumentally in terms of product output rather than in design process terms. A disjunction is found between the statutory Order on Design and Technology and its implementation, with many teachers ’constructing‘ their design and technology education programmes within a ’craft paradigm‘. The discussion offers possible explanations for this and concludes that it has as much to do with the perceived status of Design and Technology as a school subject as with a ’product – process‘ debate. This revised version was published online in August 2006 with corrections to the Cover Date.     

Student response to an Internet-mediated industrial design studio course

The purpose of this study is to investigate student attitudes towards and perceptions of using the Internet and information technology to mediate a design studio course and to propose guidelines and suggestions for developing Internet-mediated design studio courses. Two classes of third-year undergraduate industrial design students in two collaborating universities in Taiwan—Chang Gung University and National Yunlin University of Science and Technology—participated in an experimental design studio course mediated with an online design learning environment. Surveys and focus group interviews were conducted at the end of the course to record students’ attitudes and perceptions. The students thought that the approach used had a positive influence on design teaching and learning and expressed acceptance of using the Internet to support design education. Finally, suggestions were proposed to help design educators in adopting, modifying, and developing systems for using the Internet to mediate design studio courses.     

Learning by collaborative designing: technology-enhanced knowledge practices

The purpose of the present article is to examine the knowledge-practice based approach to technology-enhanced learning. Toward that end, the article reports the efforts of an elementary-school teacher and researchers in promoting genuine inquiry at the 4th and 5th grade of a Finnish elementary school. We will describe implementation and social organization regarding ‘The Project of Artefacts––the Past, the Present and the Future’ that engaged students in collaborative inquiry and design across 13 months (almost three semesters). Knowledge Forum (KF), a virtual platform for the interchange of information, provided tools and practices that facilitated creative working within participating students and teachers. This was accomplished in a meaningful social setting which was culturally rich and where material and conceptual artefacts played dominant roles. In this article, the analysis of the teacher’s project diary and the contributions to the KF database provides an overview of the knowledge practices enacted during the project. The distribution of knowledge-creation activities during the project reveals that the teacher assumed a role of organizer concerning shared knowledge practices instead of controlling all aspects of students’ learning. Simultaneously, however, students were not left working without guidance; the teacher structured their collaborative efforts with the help of KF and by directing classroom activities.     

The effect of alternative approaches to design instruction (structural or functional) on students’ mental models of technological design processes

The study aimed to examine the relationship between alternative approaches towards problem solving/design teaching (structural or functional), students’ mental modeling of the design process, and the quality of their solutions to design tasks. The structural approach emphasizes the need for an ordered and systematic learning of the design process stages, while the functional approach emphasizes the teaching and study of design functions (rather than stages). Participants were 80 seventh graders, divided into two groups, who were taught a unit on technological problem solving by either approach in the course of 14 classes (21 h) during a semester. Before, during and after the design process of a technological solution the students represented their perception of the design process. The results for both groups were analyzed in terms of: (a) types of models generated; (b) changes in type of models along the learning/design process; (c) defining characteristics of the design process models. Significant differences between the groups’ models were found for most variables examined. The functional approach was more effective than the traditional structural approach for supporting the construction of holistic, flexible, and effective mental models of the design process of technological solutions.     

The attitudes of interior design students towards sustainability

To measure attitudes toward environmental issues, interior design students responded to a four-part survey: demographics, ecology, sustainability, and comments. The ecology section was composed of modifications of questions from the New Ecological Paradigm Scale (Dunlap et al. Journal of Environmental Education, 9:10–19, 2000). The researchers composed the items in the sustainable section to reflect perceptions related to the use of sustainable products and solutions in interior design scenarios. Although the ecology and sustainability survey results exhibited great variability, responses to individual items mostly averaged towards the more pro-environmental and pro-sustainability sides of the scales. While average scores on the ecology section of the survey showed the respondents as a group to be moderately pro-environmental, most items revealed a considerable amount of undecided ratings and quite a few students who perceived the environment to be somewhat invincible. The data also indicated a discrepancy between what students think they know (sustainability section) and what the students actually reveal in their open-ended answers (comments section). The survey results imply that educators, who themselves are likely to be pro-environment, cannot merely assume that their students share the same values and attitudes. Beginning instruction with explanations and examples of sustainable methods and products will not be sufficient to communicate the delicate balance between Human use of resources and Nature’s ability to replenish. Design educators need to set the stage for sustainability rather than just assume that students will embrace the concept. Hopefully, more research studies will inspire others to evaluate their own students’ feelings about the environment.     

3D simulation technology as an effective instructional tool for enhancing spatial visualization skills in apparel design

The purpose of this study is to explore the effectiveness of 3D simulation technology for enhancing spatial visualization skills in apparel design education and further to suggest an innovative teaching approach using the technology. Apparel design majors in an introductory patternmaking course, at a large Midwestern University in the United States, participated in this study. Three different teaching methods (lecture, 3D simulation instruments, and paper patternmaking) were employed in consecutive instructional phases, within a single day. A short questionnaire devised to assess students’ visualization abilities and overall evaluation on the three different teaching methods was administered to the students after each of the three phases. Overall, students’ abilities to visualize 2D patterns onto a human body were improved by all three teaching methods. The 3D simulation instruments anchored positive effects of training on spatial visualization abilities between lecture and paper patternmaking practices. The results affirm that 3D simulation technology has positive potential as an efficient instructional tool for improving students’ visualization skills in apparel design.     

Promoting student-led science and technology projects in elementary teacher education: entry into core pedagogical practices through technological design

Future elementary school teachers often lack self-efficacy for teaching science and technology. They are particularly anxious about encouraging children to carry-out student-directed, open-ended scientific inquiry and/or technological design projects. Moreover, because this often also is the case with practising elementary school teachers, it is difficult for student–teachers to gain practical experience facilitating student-led project work during practicum sessions. To provide student–teachers with expertise and motivation for promoting student-directed, open-ended project work, therefore, a group of future elementary teachers were taken through a constructivism-informed ‘apprenticeship’ during their university-based teaching methods course and then invited to make project work the subject of the action research that they were required to complete during their practicum. In this paper, successes that one student–teacher (out of 78 studied) experienced in promoting student-directed, open-ended technological design projects are reported. Although she judged children’s designs to be modestly successful, data indicate that her self-efficacy for promoting project work increased significantly. Analyses of qualitative data collected during the methods course and practicum also indicate that aspects of the curriculum, teachers, students and milieu appeared to contribute to this success. Such findings suggest that teacher educators should focus on helping future elementary teachers to develop expertise and motivation that would enable and encourage children to conduct technological design projects before conducting scientific inquiries. Such a tack may be the most pragmatic—and, arguably, epistemologically-sound—approach for helping ‘science- and technology-phobic’ student–teachers to move from the periphery to the core of practices in science and technology education.     

Integrating innovation skills in an introductory engineering design-build course

Modern engineering curricula have started to emphasize design, mostly in the form of design-build experiences. Apart from instilling important problem-solving skills, such pedagogical frameworks address the critical social skill aspects of engineering education due to their team-based, project-based nature. However, it is required of the twenty-first century engineer to be not only technically competent and socially and culturally aware, but also innovative and entrepreneurial. This paper discusses a reformulated first-year engineering course at the University of Pretoria, which was adopted 6 years ago to better address the required innovation skills of engineering students. This design-build-innovate course employs a unique creative problem-solving strategy in designing and building solutions to set technological problems. The students further investigate the provisional patenting of their design concepts. Mini business plans are developed and the students participate in a university- and in a national innovation competition. This introductory engineering course has been successful as measured by overwhelmingly positive student feedback, several provisional patents, and a number of small start-up companies that emanated from the students’ work.     

Learning in DEPTH: developing a graphical tool for professional thinking for technology teachers

In this issue of the International Journal of Technology and Design, we report on a series of case studies from the second phase of an international project—Developing Professional Thinking for Technology Teachers (DEPTH2). The first phase of the project was a study conducted with both primary and secondary technology pre-service teacher education students in a number of different countries who were given the same teacher-knowledge graphical framework as a tool to support reflection on their professional knowledge. We discovered that, despite the different country contexts, student teachers of technology could articulate aspects of their developing teacher knowledge using the same framework for teacher professional development. As previously reported in this journal (Banks et al. International Journal of Technology and Design Education, 14, 141–157, 2004), the common graphical tool enabled them to set out their subject knowledge, pedagogical knowledge and ‘school’ knowledge and was useful in helping them become more self-aware. In this second phase of the project we have developed this line of research in two ways. First, we extended the range of participants to include experienced teachers involved in in-service work connected to curriculum development. Second, we looked at the inter-relationship for pre-service teachers between their developing professional knowledge and their own ‘personal subject construct’. In this article, the theoretical framework for the subsequent papers is described and set in the context of recent debates surrounding the nature and importance of teacher knowledge; and the way such professional knowledge can be articulated by teachers.     

Positioning industrial design students to operate at the ‘fuzzy front end’: investigating a new arena of university design education

This paper describes pedagogic research to instigate, support and understand a significant change in the education of undergraduate industrial design students. Design educators at Loughborough University, UK, have proposed that it will be critical for future industrial designers to learn new knowledge and abilities which will enable them to successfully operate at the ‘fuzzy front end’ of new product development. This is an arena before a traditional design brief exists (i.e. ‘pre-brief’), and typically involves in-depth investigation of such issues as users, experiences and brand, followed by exploitation of the findings. Curriculum development and new teaching, evolved over five annual cycles of implementation, reflection, planning and new implementation, is described. A model of the activities and processes of this ‘pre-brief’ arena is presented. Through structured investigation of the cycles of improvement and follow-up evaluation research, evidence gathered from stakeholders (students, educators, and industry) indicates that industrial design students can be taught to successfully operate at this fuzzy front end, and that this can be a highly effective strategy for students in their design project work. It also suggests that the students’ enhanced abilities will be in demand following their graduation.
