In light of growing interest in the maker movement and electronic textiles (e-textiles) as an educational technology, the purpose of this paper is to characterize competence change in undergraduate students who participated in a semester-length course that used e-textiles.

This qualitative and exploratory research study used semi-structured pre- and post-interviews with undergraduate students (N=7) thinking aloud through novel tasks in order to understand their learning from a semester-long course involving e-textiles. This design was intended to elicit student thinking with commercial toys that differed from the types of projects they had completed in their course. A coding scheme was developed and organized into an analytical rubric to map depth of understanding in the three spheres of circuitry, computation, and crafting. Select cases of pre-post change were identified to illustrate growth in specific content spheres.

Students’ ability to reason through novel tasks showed growth in each sphere, provided that the student did not begin with a full level of sophistication in a particular area during the pre-interview. Although students may not reach normative or expert-like competence, there are demonstrable indications of growth for each of the dimensions.

As e-textiles are increasingly turned to educationally, the creation and presentation of a rubric for describing competence in three spheres, especially the previously understudied area of crafting knowledge in e-textiles, is itself a useful contribution to the field. This is also an extension of e-textiles learning research into undergraduate instruction, an as-yet understudied setting for maker education.

This paper aims to present and discuss cheat sites and cheating practices associated with Whyville.net, a virtual world with over 1.7 million registered players aged eight to 16 that includes game and science activities. The goal is to examine how the development of cheats can present learning opportunities for players and designers alike.

The types of cheats were categorized and science content examined in hundreds of cheat sites created for Whyville. The work of a cheat site designer in developing a cheat together with other Whyville players was observed.

It was found that a great variety of cheats are available in educational worlds and that science games that require more than one simple answer also require the development of more sophisticated cheats.

Cheating is a transgressive practice widely accepted in gaming but mostly condemned in schooling. The features of cheating and its associated practices allow us to consider transgressive designs for learning in virtual worlds that offer opportunities for youth to participate in creative and critical media production, to engage in science inquiry, and to raise ethical issues.

This paper aims to understand in-depth the concepts applied to the domains of organizational learning (OL) and learning organization, based on the notional perspectives of Professor Deborah Blackman and traces the evolutionary path of her academic journey and contributions in this regard.

A conversation with the distinguished academician, Professor Deborah Blackman.

How OL has pivoted around “shared mental models” that will enable in collective evidence-based decision-making across the organizational hierarchy.

The interactive session with Professor Deborah Blackman captured her ideas and critique pertaining to the theme of OL and the crucial aspect of “shared mental models” which promote “learning” in an organization. Delving deeper, it is seen that this trajectory offers the space and orientation to researchers and professionals to verify.

As the 1960s drew to a close, Congress found itself grappling with an increasing array of complex technological issues that it was ill equipped to analyze and that could be the cause of costly blunders if acted upon incorrectly. To alleviate this situation, the U.S. Office of Technology Assessment (OTA) was created in 1972 under Public Law 92–484 in order to advise Congress on issues in science and technology so that relevant information would be available when pertinent legislation was being developed. Under the leadership of its director John Gibbons, OTA has earned the distinction of providing Congress, that most political of bodies, with timely and objective information without becoming mired in political skirmishes. Despite this distinction, OTA is one of the smallest government agencies, with a budget of twenty million dollars and a staff of 140. Its organization is remarkable for its simplicity. A bipartisan congressional Technology Assessment Board governs the agency overall but appoints the director who has full responsibility for running it. The nine agency divisions are organized according to scientific disciplines and report to the director with little or no intervening bureaucracy. Outside expert advice is available from the Technology Assessment Advisory Council. The result is an organization that is equally balanced politically and scientifically, that is streamlined and efficient, and that allows input from its governing members. This structure also allows great flexibility in the research and production of assessment reports. To do an assessment, OTA deploys its experts to go out and gather the information needed on the wide‐ranging topics it has been commissioned to research. The topics are chosen according to the need and interest of both houses and both political parties. Outside experts are sometimes called upon to do research but OTA exercises the final responsibility over their reports. Factual conclusions and options are presented but opinions are never given. The manner in which the information is acted upon is always left to Congress, a major reason for OTA's success.

The purpose of this paper is to report changes when a classroom-based makerspace moved from face-to-face to an online setting.

To better understand changes in teaching maker activities, as they move from face-to-face to online contexts, the authors analyzed video and interview data from six weeks of an introductory computer science high school classroom (38 youth) that was implementing an electronic textiles unit, shifting to asynchronous online teaching and learning during the March 2020 state-wide school closure because of the pandemic. The authors analyzed field notes and videos of face-to-face and online interactions between the teacher and his students in learning to craft and code their electronic textiles projects.

The analysis revealed changes in the role of physical and code artifacts, in improvising teaching, and channels for communication between the teacher and students.

This study discusses the implications for future pedagogical design and research efforts, as the authors continue to engage youth and work toward designing equitable learning opportunities with maker activities online.

In maker activities such as electronic textiles, youth design, sew and program circuits to make personalized three-dimensional, textile artifacts. However, nearly all research on supporting and teaching making has been conducted in face-to-face settings.

The purpose of this paper is to investigate the two-dimensional flow of Maxwell fluid with power law heat flux and heat source over a stretched surface.

The governing partial differential equations are reduced into ordinary differential equations by applying similarity transformations. Series solutions of velocity and temperature are found by adopting homotopy analysis method (HAM).

It is found that the velocity decreases by increasing Deborah number and suction parameter. It is also observed that the heat generation parameter leads to a decrease in temperature. Furthermore, the numerical values of local Nusselt number decreased with an increase in Deborah number.

A useful source of information for the investigators on the field of non-Newtonian fluids with heat transfer.

This paper discusses the boundary layer flow of Maxwell fluid with power law heat flux in the presence of heat source.

The purpose of this paper is to examine how a clinical interview protocol with failure artifact scenarios can capture changes in high school students’ explanations of troubleshooting processes in physical computing activities. The authors focus on physical computing, as finding and fixing hardware and software bugs is a highly contextual practice that involves multiple interconnected domains and skills.

This paper developed and piloted a “failure artifact scenarios” clinical interview protocol. Youth were presented with buggy physical computing projects over video calls and asked for suggestions on how to fix them without having access to the actual project or its code. Authors applied this clinical interview protocol before and after an eight-week-long physical computing (more specifically, electronic textiles) unit. They analyzed matching pre- and post-interviews from 18 students at four different schools.

The findings demonstrate how the protocol can capture change in students’ thinking about troubleshooting by eliciting students’ explanations of specificity of domain knowledge of problems, multimodality of physical computing, iterative testing of failure artifact scenarios and concreteness of troubleshooting and problem-solving processes.

Beyond tests and surveys used to assess debugging, which traditionally focus on correctness or student beliefs, the “failure artifact scenarios” clinical interview protocol reveals student troubleshooting-related thinking processes when encountering buggy projects. As an assessment tool, it may be useful to evaluate the change and development of students’ abilities over time.

Recent advancements in technology have led to the exploration of solar-based thermal radiation and nanotechnology in the field of fluid dynamics. Solar energy is captured through sunlight absorption, acting as the primary source of heat. Various solar technologies, such as solar water heating and photovoltaic cells, rely on solar energy for heat generation. This study focuses on investigating heat transfer mechanisms by utilizing a hybrid nanofluid within a parabolic trough solar collector (PTSC) to advance research in solar ship technology. The model incorporates multiple effects that are detailed in the formulation.

The mathematical model is transformed using suitable similarity transformations into a system of higher-order nonlinear differential equations. The model was solved by implementing a numerical procedure based on the Wavelets and Chebyshev wavelet method for simulating the outcome.

The velocity profile is reduced by Deborah's number and velocity slip parameter. The Ag-EG nanoparticles mixture demonstrates less smooth fluid flow compared to the significantly smoother fluid flow of the Ag-Fe3O4/EG hybrid nanofluids (HNFs). Additionally, the Ag-Ethylene Glycol nanofluids (NFs) exhibit higher radiative performance compared to the Ag-Fe3O4/Ethylene Glycol hybrid nanofluids (HNFs).

Additionally, the Oldroyd-B hybrid nanofluid demonstrates improved thermal conductivity compared to traditional fluids, making it suitable for use in cooling systems and energy applications in the maritime industry.

The originality of the study lies in the exploration of the thermal transport enhancement in sun-powered energy ships through the incorporation of silver-magnetite hybrid nanoparticles within the heat transfer fluid circulating in parabolic trough solar collectors. This particular aspect has not been thoroughly researched previously. The findings have been validated and provide a highly positive comparison with the research papers.

The aim of this paper is to define pracademia and conceptualise it in relation to educational contexts. This paper contributes to and stimulates a continuing and evolving conversation around pracademia and its relevance, role and possibilities.

This paper is a conceptual exploration. It draws upon existing and emerging pieces of literature, the use of metaphor as a meaning-making tool, and the positionalities of the authors, to develop the concept of pracademia.

The authors posit that pracademics who simultaneously straddle the worlds of practice, policy, and academia embody new possibilities as boundary spanners in the field of education for knowledge mobilization, networks, community membership, and responding to systemic challenges. However, being a pracademic requires the constant reconciling of the demands of multi-membership and ultimately, pracademics must establish sufficient legitimacy to be respected in two or more currently distinct worlds.

This paper has implications for knowledge mobilization, networks, boundary spanners, leadership, professional learning, and connecting practice, policy, and research. While the authors are in the field of education, this exploration of pracademia is relevant not only to the field of education but also to other fields in which there is a clear need to connect practice/policy with scholarship.

This paper provides a new definition of pracademia and argues that pracademia identifies an important yet relatively unknown space with many possibilities in the field of education.

A parabolic trough solar collector is an advanced concentrated solar power technology that significantly captures radiant energy. Solar power will help different sectors reach their energy needs in areas where traditional fuels are in use. This study aims to examine the sensitivity analysis for optimizing the heat transfer and entropy generation in the Jeffrey magnetohydrodynamic hybrid nanofluid flow under the influence of motile gyrotactic microorganisms with solar radiation in the parabolic trough solar collectors. The influences of viscous dissipation and Ohmic heating are also considered in this investigation.

Governing partial differential equations are derived via boundary layer assumptions and nondimensionalized with the help of suitable similarity transformations. The resulting higher-order coupled ordinary differential equations are numerically investigated using the Runga-Kutta fourth-order numerical approach with the shooting technique in the computational MATLAB tool.

The numerical outcomes of influential parameters are presented graphically for velocity, temperature, entropy generation, Bejan number, drag coefficient and Nusselt number. It is observed that escalating the values of melting heat parameter and the Prandl number enhances the Nusselt number, while reverse effect is observed with an enhancement in the magnetic field parameter and bioconvection Lewis number. Increasing the magnetic field and bioconvection diffusion parameter improves the entropy and Bejan number.

Nanotechnology has captured the interest of researchers due to its engrossing performance and wide range of applications in heat transfer and solar energy storage. There are numerous advantages of hybrid nanofluids over traditional heat transfer fluids. In addition, the upswing suspension of the motile gyrotactic microorganisms improves the hybrid nanofluid stability, enhancing the performance of the solar collector. The use of solar energy reduces the industry’s dependency on fossil fuels.
