A computer‐based learning environment in the field of Newtonian mechanics

This paper describes a Computer‐based Learning Environment (CBLE) whose objective is to stimulate and support learning in the field of Newtonian mechanics through exploratory activities in various microworlds. The structure of the microworld TABLE is described in detail. A pilot study is presented: it concerns the modelling process of the learner knowledge in the topic involved and the evaluation of the impact of the exploratory activity on student learning. Some suggestions drawn from the results are discussed.     

Voice in the agentic assemblage

Abstract

In this article, we explore how a posthumanist stance has enabled us to work a different consideration of the way in which voice is constituted and constituting in educational inquiry; that is, we position voice in a posthuman ontology that is understood as attributable to a complex network of human and nonhuman agents that exceed the traditional understanding of an individual. Drawing on the work of Deleuze and Guattari, Barad, and Bennett, we present a research artifact that illustrates how this posthuman voice is productively bound to an agentic assemblage. The reconfiguration of a posthuman voice with/in an educational research artifact further enables us to explore various analytic questions: What happens when voice exceeds language and is more than (un)vocalized words emanating from a speaking subject? If the materiality of voice is not limited to sound (i.e. self-present language emitted from a human mouth), how do we account for it? That is, how might the materiality of voice be located in the space of intra-action among human and non-human objects? We conclude with implications for thinking qualitative methodology in education differently.

Individuating ‘sparks’ and ‘flickers’ of ‘a life’ in dance practices with preschoolers: the ‘monstrous child’ of Colebrook's Queer Vitalism

ABSTRACT

What are the dominant images of the Child in contemporary Western societies? In order to challenge some dominant images of the Child, this essay explores the possibilities of analyzing an experimental dance practice with preschoolers aged 1–2 years with Claire Colebrook's theorizing on ‘the war on norms’. Colebrook suggests a Queer Vitalism to push the limits of how to understand humanness generally, and more specifically, how to understand processes of subjectification. She moves from a post-structuralist understanding toward the Deleuzian notion of practices of individuation and processes of becoming-imperceptible. In this essay, we draw on Queer Vitalism to show how it is possible to understand children's constructions of subjectivity in events of experimental dance practices for preschoolers. The analysis is performed in close interactions with video-films from these workshops transformed to still photography. We aspire to show how these practices can be understood as counter-power strategies in the enactment of an image of a Monstrous Child. Such an image might transform the taken-for-granted image of the Child and preschool practices in subversive ways.     

Fluid Mechanics and Complex Variable Theory: Getting Past the 19th Century

Abstract

The subject of fluid mechanics is a rich, vibrant, and rapidly developing branch of applied mathematics. Historically, it has developed hand-in-hand with the elegant subject of complex variable theory. The Westmont College NSF-sponsored workshop on the revitalization of complex variable theory in the undergraduate curriculum focused partly on identifying scientific areas where complex variables plays an active role. The author presented a lecture on this topic and here we highlight parts of that presentation and follow-up discussion.     

What Students Want: A Vision of a Future Online Learning Experience Grounded in Distance Education Theory

ABSTRACT

As online learning continues to evolve many have proposed that we think differently about our pedagogical approaches, to move beyond the replication of the face-to-face experience. Here we explore the student and faculty visions of the future using a Zaltman Metaphor Elicitation (ZMET) method that uses images to metaphorically represent how individuals feel or relate to particular concepts. Focus group interviews with a small sample of faculty and students suggest a desire for a more personalized learning experience, but one that is still highly social within learning communities.

Learning and Innovation in Agriculture and Rural Development: The Use of the Concepts of Boundary Work and Boundary Objects

Abstract

Purpose: The paper explores the role of boundary work and boundary objects in enhancing learning and innovation processes in hybrid multi-actor networks for sustainable agriculture (LINSA).

Design/Methodology/Approach: Boundary work in LINSA is analysed on the basis of six case studies carried out in SOLINSA project under a common methodology. In developing typologies of boundary work and objects, a grounded approach is used.

Findings: LINSA analysis demonstrates the dynamic character, diverse forms and multiple functions of boundary work and objects in three domains: learning, innovation, and sustainability. Addressing specific types of goals and actors leads to specific types of boundary work and boundary objects. Context-appropriate boundary work allows aligning differing actor attitudes, gaining increased external support, and developing LINSA. The concepts of boundary work and boundary objects are relevant in a broad range of divergent LINSA settings. Boundary work has its limitations, but its facilitation supports reaching LINSA goals.

Practical Implications: The paper proposes recognising context-appropriate forms of boundary work and skilful use of emerging boundary objects to both promote internal consolidation of LINSA and effective external communication to foster learning and innovation for sustainability.

Originality/Value: The paper provides insights into the forms, dynamic and outcomes of boundary work in LINSA in three key domains: developing shared knowledge base, co-producing innovation and negotiating sustainability.     

Drawing relationally for an ethnography of practice

ABSTRACT

Education ethnographies show that observing bodies, objects and settings can illuminate previously hidden learning practices but the relational characteristics of these practices presents methodological challenges for conventional qualitative analyses. Using an example from an ethnographic study of everyday learning, I show how methods from art (specifically researcher-created drawings) can address some of these challenges. I use the concept of ‘epistemic objects’ to theorise drawings as analysis, and to show that rather than being a process of deconstruction, this analysis is constantly bringing knowledge into being. With original interdisciplinary insights from art/social science, this article problematises art in sociomaterial research and offers direction for relational analyses.     

Exploring Mathematics Teacher Educator Questioning as a Relational Practice: Acknowledging Imbalances

ABSTRACT

The desire to understand our questioning practices as relational led us to use collaborative self-study to construct images of our questioning practice within our mathematics teacher education practices. In a prior exploration of written feedback we had begun to consider how our practices supported relationships with preservice teachers. As a result, we began to consider ways we engaged preservice teachers during instruction and wondered how our questions supported or constrained growth of relationships. In this article we share ways our expectations for what we call balance in our questioning practices were disrupted. We describe three waves of inquiry that gave form to our exploration and resulted in awareness of the role and anticipation of imbalance in our questioning practice. Each new wave resulted from findings of the previous waves and pushed us back to the research literature and forward to new images of our questioning. We tell our story using one episode from our practice, images of that practice shared at the 2018 Castle Conference, and lenses that help us anticipate imbalance in our practice.     

Introducing quantum mechanics in the upper secondary school: A study in Norway

The study reported in this paper is a survey (n=236) that examines how upper secondary students (18-19 years old) in Norway come to terms with the wave-particle duality as presented as part of a short introduction to quantum physics. The main conclusion is that this concept is poorly understood. Some students demonstrate clear and explicitly formulated misconceptions rooted in a classical physics world-view. Scholars in physics have stated that the concept of duality is unnecessary, but still included in school and university physics. It is argued that school physics should give a more explicit focus to the challenge that quantum physics presents to the classical worldview, thus introducing the importance of an affective dimension in the learning and teaching of quantum physics. This study replicates evidence from other studies that wave-particle duality does not introduce such a challenge.     

Malala: the story of a Muslim girl and a Muslim nation

ABSTRACT

In this article, we analyze the coverage of Malala in The New York Times and The Wall Street Journal to explore how these influential media sources characterize Islam and Pakistan to tell Malala’s story. Our discourse analysis reveals how these newspapers construct Malala’s status as a global icon as an embodiment of her subject position as a girl. This media discourse mobilizes Malala’s agency in relation to her potential as an individual whereas her vulnerability as a young girl is presented in reference to her Muslim heritage and culture. Malala’s image as a global icon, thus, is produced through approaching her as an agent in a culture where girls are vulnerable victims of patriarchy. Through focusing on this media discourse, this article argues that Malala’s image as a global icon of girls’ education has become a site to reinsert, rather than challenge, the dominant images about Islam and Muslim societies.     

Students’ ideas about prismatic images: teaching experiments for an image-based approach

ABSTRACT

Prismatic refraction is a classic topic in science education. To investigate how undergraduate students think about prismatic dispersion, and to see how they change their thinking when observing dispersed images, five teaching experiments were done and analysed according to the Model of Educational Reconstruction. For projection through a prism, the students used a ‘split image projection’ conceptualisation. For the view through a prism, this conceptualisation was not fruitful. Based on the observed images, six of seven students changed to a ‘diverted image projection’ conceptualisation. From a comparison between students’ and scientists’ ideas, teaching implications are derived for an image-based approach.     

Shape Makers

Summary

Professional standards for school mathematics recommend that dynamic geometry programs such as the Geometer's Sketchpad can and should be used to enhance student learning of geometry. This article illustrates how a geometry computer microworld containing screen manipulable, dynamically transformable shape-making objects can promote the development of powerful geometric reasoning. Also described is the overall context and factors that should guide mathematics educators' design and use of instructional technology.     

Two Project Methods: Preliminary observations on the similarities and differences between William Heard Kilpatrick’s project method and John Dewey’s problem-solving method

Abstract

The project method became a famous teaching method whenWilliam Heard Kilpatrick published his article ‘Project Method’ in 1918. The key idea in Kilpatrick’s project method is to try to explain how pupils learn things when they work in projects toward different common objects.The same idea of pupils learning by work or action in an environment with objects also belongs to John Dewey’s problem-solving method. Are Kilpatrick’s project method and Dewey’s problemsolving method the same thing? The aim of this article is to analyze and prove that Kilpatrick’s project method differs radically from Dewey’s problem-solving method.     

Kuhn's Paradigm and Example‐based Teaching of Newtonian Mechanics

Summaries

English

According to Kuhn, normal scientific work is developed not mainly from basic axioms, but by the development of the fundamental examples and demonstrations of the paradigm. For disciplines still at the research frontier, education can also only be example‐based rather than axiomatic, but for disciplines which have become classical, such as Newtonian mechanics, teaching should be performed using more formal methods. In practice this does not appear to be the case, and a number of simple problems in mechanics are cited where example‐based teaching commonly leads to misunderstanding. A recommendation is made for more direct teaching of the basic principles of mechanics.     

Researching ‘messy objects’: how can boundary objects strengthen the analytical pursuit of an actor-network theory study?

ABSTRACT

This paper offers a detailed consideration of how the theoretical scope of the boundary object concept fits within an actor-network theory (ANT) sensibility when researching ‘messy objects’. Messy objects are artefacts whose relational effects are inherently slippery and complex. As the aim of ANT is to show how non-human and human actors are co-constitutive in performing social activity, the uptake of boundary objects in ANT studies may appear to be an expedient analytical endeavour. However, scholars have raised concerns that the boundary object concept has lost some of its original analytical bearing, and that it is theoretically incompatible with ANT. This paper argues that a more careful reading of boundary objects’ conceptual origins can provide useful insights for an ANT study. To illustrate this argument, findings are presented from an ethnographic study of engineers’ knowledge practices in an emerging industry. Specifically, it shows that when a messy object – a signature on a contract – is foregrounded as a boundary object, particular knowledge practices are made visible. However, due to the complexity and messiness of the signature’s performance, this paper contends that a pluralist theoretical approach to analysing messy objects may be more helpful to address issues of professional practice and knowledge.     

Facilitating conditions for farmer learning behaviour in the student-to-farmer university outreach

Purpose: This study elucidates on how faculty supervision support to students during farm placements and other facilitating conditions influence farmer learning in the student-centred university outreach.

Methodology/Design/Approach: Cross-sectional data were collected from a sample of 283 farmers who had previously hosted students of Gulu University in the student-to-farmer university outreach. Structural equation modelling was used to analyse how faculty supervision support to students in combination with other facilitating conditions affect the formation of intentions for learning and actual farmer learning behaviour.

Findings: Faculty supervision support in the student-to-farmer outreach was found to significantly influence formation of intentions for learning (β?=?0.380; t?=?5.263; P?β?=?0.182; t?=?2.081; P?Practical implications: Faculty supervision support to students is critical to fostering lasting learning relationships in university outreach. Thus, it needs to be a part of the transformation agenda of the higher education sector for improved community linkages and innovation.

Theoretical implications: Empirical data obtained from the context of student-centred university outreach is used to extend the model of facilitating conditions.

Originality/Value: The study addresses how faculty supervision support together with farmers’ perception of student attitudes and the value of the learning content influence farmers’ learning behaviour during university outreach.     

Teaching OO Software Engineering by Example: The Games Factory

Object‐oriented analysis, design, and programming is a software development technology which has attracted universal attention in the past few years. We do not think that object‐oriented technology is a completely new approach to software construction; it is merely the consequent continuation of software engineering principles which have evolved since 1968, the year of the birth of software engineering. This article describes a course on software engineering with objects which track the evolution of this discipline. We work through the history of these concepts using a single application domain, demonstrating how the relevant analysis and design methods evolved over time, culminating in object‐oriented techniques.     

Storylines in the physics teaching content of an upper secondary school classroom

ABSTRACT

Background: Physics is often seen as a discipline with difficult content, and one that is difficult to identify with. Socialisation processes at the upper secondary school level are of particular interest as these may be linked to the subsequent low and uneven participation in university physics. Focusing on how norms are construed in physics classrooms in upper secondary school is therefore relevant.

Purpose: The purpose of this paper is to identify discursive patterns in teacher–student interactions in physics classrooms.

Design and methods: Three different physics lessons with one class of students taught by three different teachers in upper secondary school were video-recorded. Positioning theory was used to analyse classroom interaction with a specific focus on how physics was positioned.

Results: We identified seven different storylines. Four of them (‘reaching a solution to textbook problems’, ‘discussing physics concepts in order to gain better understanding’, ‘doing empirical enquiry’ and ‘preparing for the upcoming exam’) represent what teaching physics in an upper secondary school classroom can be. The last three storylines (‘mastering physics’, ‘appreciating physics’ and ‘having a feeling for physics’) all concern how students are supposed to relate to physics and, thus, become ‘insiders’ in the discipline.

Conclusions: The identification and analysis of storylines raises awareness of the choices teachers make in physics education and their potential consequences for students. For example, in the storyline of mastering physics a good physics student is associated with ‘smartness’, which might make the classroom a less secure place in general. Variation and diversity in the storylines construed in teaching can potentially contribute to a more inclusive physics education.
