Teaching science through designing technology

This paper is a review of the literature related to teaching science through designing technology. The premise of this method is that designing technology presents the students with the context through which they can apply the science concepts they learned and thus enhancing their understanding of these concepts. Despite the promise of this method, teachers attempting it were faced by many challenges such as: (1) teachers did not have a grasp of the complex relationship between science and technology and assumed that technology was simply applied science, (2) the students were not able to transfer their learning of science to designing technology, (3) teachers did not have a deep understanding of the design process and tried to teach it as a linear, context-free process without regard to the context of the problem. The purpose of this paper is to extract from the literature a better understanding of teaching science through designing technology and the elements that teachers need to satisfy in order to increase their chances of successfully implementing this method in the classroom.     

Fostering creativity from an emotional perspective: Do teachers recognise and handle students’ emotions?

Emotions have a significant effect on the processes of designing and creative thinking. In an educational context, some emotions may even be detrimental to creativity. To further explore the link between creativity and emotion, a series of interviews were conducted with design and technology (D&T) teachers in Singapore, Hong Kong and Beijing concerning their experiences of working with students on design projects. The intent was to investigate how these teachers understood and managed their students’ emotions while teaching creative design skills. Some teachers indicated that they understood their students’ emotions through observing their behaviour, connecting with them by synchronising emotions or by evaluating student performance. The teachers also reported using various other methods to handle their students’ emotions. This study highlights the importance of equipping D&T teachers with skills for awareness and regulation of emotions so that they can better enable students to cultivate creativity in the design process.     

Taking part in the dance: technology teachers interacting with communities of practice

This research investigated how secondary school technology teachers planned and implemented units that enabled students to access authentic technological practice through their contact with a community of practice (CoP). It was found that when teachers plan to access a community of practice for their students a complex dance-style relationship develops between the three parties involved. Unplanned interactions can have a significant effect on the planned teaching unit. If teachers are reflexive to the demands of the student and the CoP representative, there is the potential for the development of teaching programmes with technological outcomes that reflect authentic technological practice.

Swedish technology teachers’ views on assessing student understandings of technological systems

Technology education is a new school subject in comparison with other subjects within the Swedish compulsory school system. Research in technology education shows that technology teachers lack experience of and support for assessment in comparison with the long-term experiences that other teachers use in their subjects. This becomes especially apparent when technology teachers assess students’ knowledge in and about technological systems. This study thematically analysed the assessment views of eleven technology teachers in a Swedish context. Through the use of in-depth semi-structured qualitative interviews, their elaborated thoughts on assessing knowledge about technological systems within the technology subject (for ages 13–16) were analysed. The aim was to describe the teachers’ assessment views in terms of types of knowledge, and essential knowledge in relation to a progression from basic to advanced understanding of technological systems. The results showed three main themes that the interviewed teachers said they consider when performing their assessment of technological systems; understanding (a) a system’s structure, (b) its relations outside the system boundary and (c) its historical context and technological change. Each theme included several underlying items that the teachers said they use in a progressive manner when they assess their students’ basic, intermediate and advanced level of understanding technological systems. In conclusion, the results suggest that the analysed themes can provide a basis for further discussion about defining a progression for assessing students’ understanding about technological systems. However, the findings also need to be examined critically as the interviewed teachers’ views on required assessment levels showed an imbalance; few students were said to reach beyond the basic level, but at the same time most assessment items lay on the intermediate and advanced levels.     

Learning design and technology through social networks for high school students in China

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.     

Knowing what engineering and technology teachers need to know: an analysis of pre-service teachers engineering design problems

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

Intellectual property: what do teachers and students know?

As society changes from an industrial to a knowledge era increasing importance and value is being placed on intellectual property rights. Technology teachers need to have pedagogical content knowledge of intellectual property if they are to incorporate it into their learning programmes to enable students to consider how to respect others’ intellectual property rights, how to protect their own ideas and how they can legitimately make use of others’ intellectual property. A survey of technology teachers and a small sample of students was undertaken to ascertain their knowledge of intellectual property and any misconceptions which may exist. The findings reflect an awareness of relevant concepts but confusion between key terms such as patent, copyright and registered design.     

Using scientific detective videos to support the design of technology learning activities

This article examines the effect of scientific detective video as a vehicle to support the design of technology activities by technology teachers. Ten graduate students, including current and future technology teachers, participated in a required technology graduate course that used scientific detective videos as a pedagogical tool to motivate their interest in science and technology and to reinforce creative competence in designing technology learning activities (TLAs). The participants watched three scientific detective videos and analyzed them for scientific principles and technologies. An analysis report and interview were conducted to collect participants’ understanding and application of scientific principles and technologies. The main findings were that (a) influencing teacher’s design of TLAs through scientific detective videos is feasible; (b) prior personal conditions and external factors influence teacher’s design of TLAs; and (c) the analysis of scientific detective videos helps teachers to design TLAs appropriately. This study demonstrated the broad utility of scientific detective videos for inspiring technology teachers to integrate science and technology in their activity design.     

The Place of Authenticity in Technology in the New Zealand Curriculum

In 1999 Technology in the New Zealand Curriculum became mandatory. It was developed over a period of approximately four years from conception to publication, with wide consultation. It was first published in October 1995. During the three years between publication and gazetting many teachers were involved in professional development. During this time it became obvious that there was confusion amongst teachers about the meaning of `authenticity' in relation to technology programmes. Do technological problems need to be authentic to the students themselves or to the nature of technological practice? Many learning theories have informed the development of this document. Those selected here indicate quite clearly the meaning and context of authenticity with regard to technology education. By involving our students in activity that is authentic to technological practice or real world technology, teachers are able to provide stimulating and relevant learning for students. This was also the indication in recent communication from the Ministry of Education in New Zealand during the 1999 Technology Education New Zealand (TENZ) conference. By giving academic value to technology and developing our teachers in the fields of technological practice we hope our students will influence the economic status of our country in the future.     

Uncovering procedural knowledge in craft,design, and technology education: a case of hands-on activities in electronics

Different knowledge types have their own specific features and tasks in the learning process. Procedural knowledge is used in craft and technology education when students solve problems individually and share their working knowledge with others. This study presents a detailed analysis of a one student’s learning process in technology education and the procedural knowledge used during learning tasks. Thus, procedural knowledge is mainly produced when acting, and includes students’ goal-directed actions related to the craft, design and technology processes and their learning content. These knowledge practices also include multiple interactions with teachers and other students. The findings show six different knowledge practices: observing, checking and asking, revising, guided representative action, self-directed representative action, and comprehended action. These knowledge practices actively relate to each other, and, in concert, they constitute chains of actions that constitute two different types of procedural knowledge: proactive knowledge and executive knowledge. We conclude by discussing how these knowledge practices can be used to develop our understanding of the teaching and learning of craft, design and technology.     

Visible parts,invisible whole: Swedish technology student teachers’ conceptions about technological systems

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.

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.     

A future-focused approach to the technology education curriculum: the disparity between intent and practice

The recently revised New Zealand Curriculum in technology education [Ministry of Education (MoE) Digital technologies: Hangarau Matihiki, Wellington, 2017. https://education.govt.nz/assets/Documents/Ministry/consultations/DT-consultation/DTCP1701-Digital-Technologies-Hangarau-Matihiko-ENG.pdf] presents opportunities for teachers to provide a future-focused approach to learning. Teacher perceptions about the nature of their subject and the discourse within their school however, influence how the curriculum is interpreted, for enactment. This article reports findings from Ph.D. research that explored the disparity between the intent of the technology curriculum and the practice of five technology teachers, in two secondary school settings. There is a focus on the ways that teachers might be supported to navigate challenges and enable change in their practice, if they are motivated to enact technology education in a future-focused way. Teachers’ interpretation and enactment of the New Zealand curriculum are heavily influenced by others’ understanding of their subject, and the organisational structures in their school. A threshold concept is presented as a strategy to transform teachers’ thinking, when making meaning of the curriculum, and to develop their knowledge for practice. Recommendations are made regarding the necessary changes in thinking and practice in technology education in New Zealand, to address a further disparity between what school-based practitioners believe students need and what academic researchers assert is important in contemporary education. Initial Teacher Education Programmes are briefly discussed as a means of addressing this issue from another perspective, to ensure that student teachers are exposed to future-focused conceptions of the curriculum at University, to compensate when such practice is not observed during their school placements.     

DEPTH – Developing Professional Thinking for Technology Teachers: An International Study

The tools to help teachers reflect on their professional knowledge are few in number, and often difficult to utilise. This paper reports on a study conducted with both primary and secondary technology initial 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 own professional knowledge. We wanted to investigate if, despite the different country contexts, student teachers of technology could take advantage of their experience with graphic visualisation to help them articulate abstract notions such as aspects of their developing teacher knowledge. We discovered that the graphical tool acted as a framework that 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 paper, the framework itself is introduced, the way it was presented to the novice teachers is outlined and the relative impact of such `self awareness' on their understandings, enabled by the framework, is then discussed. This revised version was published online in July 2006 with corrections to the Cover Date.     

Passionate about designing

In the school based subject of design and technology (D&T) a fundamental element is designing and making functional products using critical and creative thinking whilst developing skills in the use of a variety of processes and materials. Teachers of the subject need to be more then just ‘enthusiastic’ about the processes involved if they are to develop enthusiasm in their pupils that will sustain them through the exciting but sometimes arduous and difficult processes required to achieve outcomes of which they and their teachers can be proud. The intention of this research project, using an initial sample of forty-nine students and a non-probability purposive sample of ten students studying to become D&T teachers was to tease out the factors which appear to enable some students to be passionate about creating a product to a given brief while others from similar backgrounds and expectations, given the same brief, and in the same learning situation, do not reach this level of enthusiasm. The data collection method used was an attitude scale and semi-structured interviews which were qualitatively analysed in order to identify factors involved, with the intention of informing and improving the way the authors teach their students, to design, and about design, with the additional aim of improving the students teaching of that activity once they become D&T teachers. Within the full paper results are discussed and tentative conclusions drawn.     

Teachers’ views about technical education: implications for reforms towards a broad based technology curriculum in Malawi

Internationally there has been concern about the direction of technical education and how it is positioned in schools. This has also been the case in Malawi where the curriculum has had a strong focus on skills development. However, lately there has been a call for enhancing technological literacy of students, yet little support has been provided for teachers to achieve this goal. This paper reports from a wider study that looked at teachers’ existing views and practices in technical education in Malawi. The article focuses on the findings from interviews that were conducted with six secondary school teachers to find out about their understanding of the meaning and rationale for technical education. It is also discussed how the teachers view technical education as involving skills development for making things and their thoughts on the benefits of such knowledge. It is argued that teachers’ views about technical education were strongly linked to the goals of the curriculum vacationalization policies adopted at the dawn of political independence. Besides skills training they saw the potential to impart thinking skills related to design and problem solving, and the need for essential pedagogical techniques to support learning in technical education. Examination requirements, inadequate opportunities to conduct practical activities and a lack of supportive policy were seen as limiting factors. This article claims that teachers’ views were shaped by their expectations and beliefs about the nature of technical education and what they perceived students may gain from such learning. Their views were also influenced by contextual factors which may have implications on reforms towards broader notions of technology education.     

Attitudes towards science, technology, engineering and mathematics (STEM) in a project-based learning (PjBL) environment

Many scholars claimed the integration of science, technology, engineering and mathematics (STEM) education is beneficial to the national economy and teachers and institutes have been working to develop integrated education programs. This study examined a project-based learning (PjBL) activity that integrated STEM using survey and interview methods. The participants were 30 freshmen with engineering related backgrounds from five institutes of technology in Taiwan. Questionnaires and semi-structured interviews were used to examine student attitudes towards STEM before and after the PjBL activity. The results of the survey showed that students’ attitudes to the subject of engineering changed significantly. Most of the students recognized the importance of STEM in the science and engineering disciplines; they mentioned in interview that the possession of professional science knowledge is useful to their future career and that technology may improve our lives and society, making the world a more convenient and efficient place. In conclusion, combining PjBL with STEM can increase effectiveness, generate meaningful learning and influence student attitudes in future career pursuit. Students are positive towards combining PjBL with STEM.
