Engineering problem-solving knowledge: the impact of context

Employer complaints of engineering graduate inability to ‘apply knowledge’ suggests a need to interrogate the complex theory-practice relationship in twenty-first century real world contexts. Focussing specifically on the application of mathematics, physics and logic-based disciplinary knowledge, the research examines engineering problem-solving processes as enacted by recent graduates in a range of industrial settings. Theoretically situated in the sociology of education, the Bernsteinian concept of knowledge structures and Legitimation Code Theory epistemic relations are utilised to surface the disciplinary basis of problem solving in different sociotechnical contexts. It is argued that the relationship between the ‘what’ and the ‘how’ of the problem gives rise to significantly different practice ‘codes’ between which successful engineering problem-solvers are required to shift. This paper presents two contrasting case studies which demonstrate the impact of the environment on code-shifting practices. Findings suggest that engineering curricula need to facilitate a more conceptual grasp of contextual complexities.     

Role of environmental interaction in interdisciplinary thinking: from knowledge resources perspectives

This article examined the role of environmental interaction in interdisciplinary thinking and the use of different knowledge resource types. The case study was conducted with two classes (N?=?40) of 8th-grade students, ages 13 to 14. The outdoor trail aimed to help students synthesize history, geography, and science knowledge. Two groups’ discourse from each class was audio-­recorded and transcribed for content analysis. We coded the discourse to examine: (i) the use of different knowledge resource types (i.e., contextual resource, new conceptual resource, prior knowledge resource); (ii) the relationship among these knowledge resource types; and (iii) evidences of interdisciplinary thinking. Findings showed that contextual resources enhanced students’ capacity to develop new conceptual resources and to activate prior knowledge resources. Further, about 80% of students’ discourse demonstrated interdisciplinary connections of two subjects.     

Simulation games in science education‡

The astronomy concepts of 345 young people were studied over a 10‐year period using a multi‐media, multi‐modal methodology in a research design where survey participants were interviewed three times and control subjects were interviewed twice. The purpose of the research was to search for evidence to clarify competing theories on conceptual coherence versus knowledge‐in‐pieces, distinguishing between coherence as revealed in the representational systems at any particular stage in a young person’s development and the changes evident in mental growth thereafter. Thus five research questions concerned with the elements and structure of understanding were investigated: (1) conceptual coherence shown as patterns of high correlation of concept representations between the media used to assess subjects’ understanding within a survey, as well as (2) coherence revealed as consistency of representation of those concepts across media and modalities; (3) enhanced conceptual understanding and skill through repeated interviews across (longitudinal) surveys, as young people develop their knowledge; (4) cultural similarity in subjects’ representations of basic static concepts (e.g. the shape of the Earth); and (5) improved understanding of basic dynamic concepts (e.g. the motion of the Earth) and complex dynamic concepts (e.g. seasons and eclipses), through “knowledge‐skill compounding”. The research findings supported conceptual coherence and rejected the counter argument of knowledge‐in‐pieces (at an alpha level of .05). Further research is recommended to replicate current research in cultures other than those of China and New Zealand studied here to confirm the view that cognition and knowledge are inherently coherent in young people.     

Dewey and mathematical practice: revisiting the distinction between procedural and conceptual knowledge

We identify a recent trend in school mathematics as well as in some of the research literature in mathematics education: an emphasis on the practical uses of mathematics and an increased emphasis on verbalizations as opposed to numerical and computational skills. With tools provided by John Dewey, an early advocate of contextual and practical knowledge, we analyse the common research framework for discussing mathematical knowledge in terms of the procedural and the conceptual. We argue that procedural and conceptual knowledge should not be seen as opposites, and that the tendency to treat them as such might be avoided by emphasising the notion of operational skill. We argue that this is important in order for the students to gain both the contextual knowledge and the computational skill entailed in mathematical knowledge.     

The PISA Tasks: Unveiling Prospective Elementary Mathematics Teachers’ Difficulties with Contextual,Conceptual, and Procedural Knowledge

The aim of this mixed methods study was to investigate the difficulties prospective elementary mathematics teachers have in solving the Programme for International Student Assessment (PISA) 2012 released items. A mathematics test consisting of 26 PISA items was administered, followed by interviews. Multiple data were utilized to provide rich insights into the types of mathematical knowledge that a particular item requires and prospective teachers’ difficulties in using these knowledge types. A sample of 52 prospective teachers worked the mathematics test, and 12 of them were interviewed afterwards. The data-sets were complementary: the quantitative data showed that PISA items could be categorized under contextual, conceptual, and procedural knowledge and indicated the most frequent difficulties in the combined contextual, conceptual, and procedural knowledge items. The qualitative data revealed that few prospective teachers could give mathematical explanations for conceptual knowledge items, and that their contextual knowledge was fragmented. Educational implications were discussed.     

Meta-assessment in a project-based systems engineering course

Project-based learning (PBL) facilitates significant learning, but it poses a major assessment challenge for assessing individual content knowledge. We developed and implemented an assessment approach and tool for a mandatory undergraduate systems engineering PBL-based course. We call this type of assessment student-oriented meta-assessment. Research participants included 131 undergraduate engineering students who carried out team projects requiring conceptual modelling of complex systems. Next, individual students assessed their peer team projects. Finally, the course staff assessed students individually, based on the content knowledge that was reflected in students’ comments to their peers, by using the new meta-assessment tool. The research findings validated the meta-assessment tool which can serve for assessing various PBL courses. Our contribution is twofold: a new approach for assessing project-based undergraduate engineering courses, and classification of meta-assessment methods into three types, where a student-oriented meta-assessment as one of the three meta-assessment methods is our newly introduced and validated method.     

Developing knowledge intensive ideas in engineering education: the application of camp methodology

Background: Globalization, technological advancement, environmental problems, etc. challenge organizations not just to consider cost-effectiveness, but also to develop new ideas in order to build competitive advantages. Hence, methods to deliberately enhance creativity and facilitate its processes of development must also play a central role in engineering education. However, so far the engineering education literature provides little attention to the important discussion of how to develop knowledge intensive ideas based on creativity methods and concepts.

Purpose: The purpose of this article is to investigate how to design creative camps from which knowledge intensive ideas can unfold.

Design/method/sample: A framework on integration of creativity and knowledge intensity is first developed, and then tested through the planning, execution and evaluation of a specialized creativity camp with focus on supply chain management. Detailed documentation of the learning processes of the participating 49 engineering and business students is developed through repeated interviews during the process as well as a survey.

Results: The research illustrates the process of development of ideas, and how the participants through interdisciplinary collaboration, cognitive flexibility and joint ownership develop highly innovative and knowledge-intensive ideas, with direct relevance for the four companies whose problems they address.

Conclusions: The article demonstrates how the creativity camp methodology holds the potential of combining advanced academic knowledge and creativity, to produce knowledge intensive ideas, when the design is based on ideas of experiential learning as well as creativity principles. This makes the method a highly relevant learning approach for engineering students in the search for skills to both develop and implement innovative ideas.     

The contribution of educational research to teachers’ professional learning: philosophical understandings

In this paper, we argue from principle that teacher education must enable a positive relationship between educational research and teaching knowledge and practice. We discuss two popular conceptions of good teaching, which conceive of the teacher as craft worker and as executive technician, and suggest that, while each of these aspects of knowing reflects something of the qualities that good teachers need, any one on its own is insufficient. In contrast to such mono-dimensional conceptions, a research-based textured notion of professional judgement encompasses a complementary and mutually enriching relationship between different aspects of professional knowledge and practice. We identify three interconnected and complementary aspects of teachers’ professional knowledge: situated understanding; technical knowledge; and critical reflection. Accordingly, teaching as professional endeavour demands of teachers practical know-how, conceptual understandings of education, teaching and learning, and the ability to interpret and form critical judgements on existing knowledge and its relevance to their particular situation. We conclude that in principle research can both enrich and be enriched by teachers’ professional knowledge and practice but that to build this relationship in a holistic way into teacher education programmes and partnership models presents considerable practical challenges.     

Conceptual and procedural approaches to mathematics in the engineering curriculum: views of qualified engineers*

The research interest underpinning this paper concerns the type of mathematical knowledge engineering students may acquire during their specialised education in terms of the conceptual and procedural dimensions of doing and using mathematics. This study draws on interviews with 25 qualified engineers from South Africa and Sweden regarding their views on the role of mathematics in engineering education, with special focus on the conceptual and procedural aspects of mathematical knowledge. A thematic analysis of the interview data led to the identification of two main themes. According to the conceptual view a predominantly conceptual approach is needed and valued more than procedural skills, while the balanced view emphasises a balance of conceptual understanding and procedural fluency as well as links between them. It is suggested that the mathematical education of engineers would need to be more conceptually oriented to prepare for the demands at the workplace.     

The use of engineering design scenarios to assess student knowledge of global,societal, economic,and environmental contexts

Product archaeology as an educational approach asks engineering students to consider and explore the broader societal and global impacts of a product's manufacturing, distribution, use, and disposal on people, economics, and the environment. This study examined the impact of product archaeology in a project-based engineering design course on student attitudes and perceptions about engineering and abilities to extend and refine knowledge about broader contexts. Two design scenarios were created: one related to dental hygiene and one related to vaccination delivery. Design scenarios were used to (1) assess knowledge of broader contexts, and (2) test variability of student responses across different contextual situations. Results from pre- to post-surveying revealed improved student perceptions of knowledge of broader contexts. Significant differences were observed between the two design scenarios. The findings support the assumption that different design scenarios elicit consideration of different contexts and design scenarios can be constructed to target specific contextual considerations.     

The Force Concept Inventory as a Measure of Students Conceptual Coherence

The Force Concept Inventory (FCI) is a multiple choice test designed to monitor students’ understanding of the conceptual domain of force and related kinematics (Hestenes et al. Physics Teacher 30:141–158 1992; Halloun et al., 1995, Online at http://modeling.asu.edu/R&E/Research.html). It has gained wide popularity among both researchers and physics instructors in the United States and elsewhere. The FCI has also been criticized, and its validity as a measure of the coherence of a student’s understanding of the force concept has been questioned. In this paper we provide a characterization of students’ conceptual coherence and a way to evaluate it using the FCI. We divide students’ conceptual coherence into three aspects: representational coherence (the ability to use multiple representations and move between them), contextual coherence (the ability to apply a concept across a variety of contexts), and conceptual framework coherence (the ability to fit related concepts together, i.e. to integrate and differentiate between them). Postinstruction FCI results and interview data from two Finnish high school groups (n=49 total) are discussed; the data provide evidence that the FCI can be used to evaluate students’ conceptual coherence—especially contextual coherence—of the force concept.     

Are contextual and designed student–student interaction treatments equally effective in distance education?

This systematic review draws from and builds upon the results of a meta-analysis of the achievement effects of three types of interaction treatments in distance education: student–student, student–teacher, and student–content (Bernard et al., Review of Educational Research, 79(3), 1243–1289, 2009). This follow-up study considers two forms of student–student interaction treatments, contextual interaction and designed interaction. Typical contextual interaction treatments contain the necessary conditions for student–student interaction to occur, but are not intentionally designed to create collaborative learning environments. By contrast, designed interaction treatments are intentionally implemented collaborative instructional conditions for increasing student learning. Our meta-analysis compared the effect of these two types of interaction treatments on student achievement outcomes. The results favored designed interaction treatments over contextual interaction treatments. Examples of designed interaction treatments and a discussion of study results and their potential implications for research and instruction in distance education and online learning are presented.     

Differences Between Attached and Detached Cadaveric Prosections on Students' Identification Ability During Practical Examinations

Cadaveric prosections are effective learning tools in anatomy education. They range from a fully dissected, sometimes plastinated, complete cadaver (in situ prosections), to a single, carefully dissected structure detached from a cadaver (ex situ prosections). While most research has focused on the advantages and disadvantages of dissection versus prosection, limited information is available on the instructional efficacy of different prosection types. This contribution explored potential differences between in situ and ex situ prosections regarding the ability of undergraduate students to identify anatomical structures. To determine if students were able to recognize the same anatomical structure on both in situ and ex situ prosections, or on either one individually, six structures were tagged on both prosection types as part of three course summative examinations. The majority of students (61%–68%) fell into one of the two categories: those that recognized or failed to recognize the same structure on both in situ and ex situ prosections. The percentage of students who recognized a selected structure on only one type of prosection was small (1.6%–31.6%), but skewed in favor of ex situ prosections (P ≤ 0.01). These results suggest that overall students' identification ability was due to knowledge differences, not the spatial or contextual challenges posed by each type of prosection. They also suggest that the relative difficulty of either prosection type depends on the nature of the anatomical structure. Thus, one type of prosection might be more appropriate for teaching some structures, and therefore the use of both types is recommended.     

African philosophy for successful integration of technology in higher education

Due partly to the multimodal and multiscalar nature of technology applications, there lacks theories to explain successful technology integration in teaching and learning in higher education. Such multidisciplinary theories developed primarily within Western contexts as behaviourism, cognitivism, constructivism, connectivism, collaborationism, TPACK framework and authentic learning theory have been used to underpin technology-enhanced teaching and learning globally. However, their primary focus on basic education and their sensitivity to contextual reality seem to restrict their salience and fecundity to successfully explain technology integration in higher education in the Global South, including Africa. For more contextual relevance and significance, the embodiment in curricula and pedagogy of African knowledge systems and emerging societal needs and challenges is thus critical. Drawing on Asabiyya and Ubuntu humanistic philosophies respectively from Northern and Southern Africa and Yoruba empiricist and Zara Yacob rationalist epistemologies from Western and Eastern Africa, this study proposes African philosophical perspectives to underpin technology integration in higher education. The epistemologies define the nature of student and faculty engagements and strategies, whereas the humanistic philosophies offer values that could guide ethical technology use and engagement. Technologies are conceived alternatively as knowledge banks, communication media and cognitive tools to think through and with. Implications for further research and practice are identified.

Practitioner notes

What is already known about this topic

• Multidisciplinary theories developed primarily within Western contexts are used to underpin technology-enhanced teaching and learning globally.
• Their primary focus on basic education and their sensitivity to socio-cultural and economic contextual reality restrict their salience and fecundity to successfully explain technology integration in teaching and learning in higher education in the Global South, including Africa.
• African philosophical, theoretical, conceptual and methodological thinking is critical for successful technology integration.

What this paper adds

• This study interrogated how African philosophies of humanity and knowledge could support successful technology integration in teaching and learning in Africa.
• Drawing on Asabiyya and Ubuntu philosophies, respectively, from Northern and Southern Africa, the study proposes strategies for making the oppressive faculty–student relationships rampant in African campuses more humane and emancipatory.
• Drawing on Yoruba empiricist and Zara Yacob rationalist epistemological orientations from Western and Eastern Africa, this study proposes strategies for supporting truly engaging and empowering pedagogies within technology-enhanced spaces.

Implications for practice and/or policy

• The purpose of education in successful technology-enhanced spaces needs to aim at improving student capacities and skills for further learning and to ensure full participation in practice communities within and outside higher education.
• The content of education or curriculum needs to primarily embody African/local philosophical, theoretical, conceptual and methodological thinking, as well as emerging community needs and challenges.
• The method of education and student assessment need to support and promote the cultivation of student skills and capabilities as well as values and ethics highly needed in their communities and beyond.

     

Mapping remote and multidisciplinary learning barriers: lessons from challenge-based innovation at CERN

This paper presents the experienced difficulties of students participating in the multidisciplinary, remote collaborating engineering design course challenge-based innovation at CERN. This is with the aim to identify learning barriers and improve future learning experiences. We statistically analyse the rated differences between distinct design activities, educational background and remote vs. co-located collaboration. The analysis is based on a quantitative and qualitative questionnaire (N?=?37). Our analysis found significant ranking differences between remote and co-located activities. This questions whether the remote factor might be a barrier for the originally intended learning goals. Further a correlation between analytical and converging design phases was identified. Hence, future facilitators are suggested to help students in the transition from one design phase to the next rather than only teaching methods in the individual design phases. Finally, we discuss how educators address the identified learning barriers when designing future courses including multidisciplinary or remote collaboration.     

Frankenstein goes to engineering school

The development of an engineering curriculum assumes a body of knowledge that students, as future engineers, will need to know. Students acquire this body of knowledge through lectures, laboratories, projects and assignments and other means. The question then arises, how does one select the content and processes that are appropriate for the engineering education? What might be the consequences of these choices? Mary Shelley's Frankenstein presents a tale showing some of the possible consequences of poor choices in teaching content and process. In Shelley's novel, the ‘monster’ finds himself caught between two worlds, one comprised of humans and the other of animals. In this allegory, the engineer is caught between the two worlds of science and art. The purpose of this allegory is to demonstrate how engineers, by accepting the body of knowledge presented to them without questioning the underlying values and assumptions, may find themselves embracing an oppressive ideology and developing an unhealthy identity. Consequently, engineering programs must provide forums where students are not only allowed but encouraged to critique the hidden values and assumptions contained in the programme content and process.     

Supporting Conceptual Change in School Science: A possible role for tacit understanding

When students reason during school science, they often refer to conceptions that are derived from out-of-school experiences and are poor proxies for science orthodoxy. However, for some areas of science, these conceptions represent only a proportion of students' full conceptual knowledge, for tacit understanding exists that is superior to the understanding displayed when reasoning. Noting that tacit understanding is engaged when events are judged as natural or non-natural, the paper is concerned with software that: (a) requires direction and speed of falling objects to be predicted, i.e. a typical science reasoning task that engages conceptual knowledge; (b) presents simulations of predicted motion in the expectation that its naturalness or non-naturalness would be recognised. An evaluation study is reported where children aged 8–12 years worked with the software in contexts that typify computer use in classrooms, i.e. individually under adult guidance (n =? 44 children) or in pairs with a classmate (n = 48 children). They were observed while they did this. Reasoning about object fall was assessed via change from individual pre-tests administered prior to software usage to individual post-tests administered a few weeks afterwards. The children who worked with the software showed greater pre- to post-test gains in conceptual understanding than control children (n =? 47 children), who lacked software experience. The gains were especially marked for the children who worked in pairs. The approach taken is contrasted with traditional approaches to conceptual change in school science, e.g. strategies that rely upon classroom experiments.     

Experimentation in biology lessons: guided discovery through incremental scaffolds

Experimentation is a complex problem-solving process. In biology lessons, experiments involve creative thinking and open discovery; however, they still require some degree of instructional guidance. The right balance between discovery learning and instructional guidance depends substantially on students’ prior knowledge. Students with low prior knowledge in particular might have difficulties with conducting and understanding experiments. Incremental scaffolds might be a valuable tool to meditate between pure discovery and strong guidance while simultaneously taking learners’ individual knowledge and skills into account. In the current study, we examined the effects of incremental scaffolds (IncSc), no scaffolds (NoSc), and worked-out examples (WoEx) on students’ knowledge acquisition while doing inquiry-based experimentation with a special focus on students with low prior knowledge. In a pre-posttest design, 193 students (M_age?=?13.02?±?0.81 years) participated in a four-hour teaching unit on animals’ overwintering strategies. In the pre- and posttest, we assessed the students’ conceptual and procedural knowledge. Our results partially confirmed our hypotheses: Regarding the conceptual and procedural knowledge of all students, incremental scaffolds showed no additional benefit regarding students’ knowledge in the posttest when compared to working with no scaffolds or worked-out examples. For the students with low prior knowledge, working with incremental scaffolds led to higher conceptual and procedural knowledge after the teaching unit than working with worked-out examples.     

Building local research capacity in higher education: a conceptual model

Building local research capacity is an enduring challenge that confronts many higher education systems particularly when aspirations for a knowledge economy dominate policymaking. While research capacity has received tremendous attention among international development agencies and scholars, the discourse is largely oriented towards infrastructure, skills training and best practices. This study interrogates the concept of local research capacity building as a dynamic process. By contrasting the policy rhetoric with the lived experiences of academics based in Kazakhstan, we propose a conceptual model to illustrate the diverse levels of research capacity building: resources, locality, relevance, human capital and culture. This study examines research capacity building in the context of the internationalisation of higher education as researchers become increasingly mobile. We argue that investing in infrastructure and human capital are insufficient for capacity building. Rather, sustainable capacity building requires research that is relevant to the local context and a cultural environment that can nurture a vibrant research community.
