The Structure of Scientific Arguments by Secondary Science Teachers: Comparison of experimental and historical science topics

Just as scientific knowledge is constructed using distinct modes of inquiry (e.g. experimental or historical), arguments constructed during science instruction may vary depending on the mode of inquiry underlying the topic. The purpose of this study was to examine whether and how secondary science teachers construct scientific arguments during instruction differently for topics that rely on experimental or historical modes of inquiry. Four experienced high-school science teachers were observed daily during instructional units for both experimental and historical science topics. The main data sources include classroom observations and teacher interviews. The arguments were analyzed using Toulmin's argumentation pattern revealing specific patterns of arguments in teaching topics relying on these 2 modes of scientific inquiry. The teachers presented arguments to their students that were rather simple in structure but relatively authentic to the 2 different modes. The teachers used far more evidence in teaching topics based on historical inquiry than topics based on experimental inquiry. However, the differences were implicit in their teaching. Furthermore, their arguments did not portray the dynamic nature of science. Very few rebuttals or qualifiers were provided as the teachers were presenting their claims as if the data led straightforward to the claim. Implications for classroom practice and research are discussed.     

Museums: Using Keyworkers to Deliver Lifelong Learning

The article describes a major study of the activities of keyworkers (mediators between museums and their public) within the context of museums' contribution to lifelong learning and to overcoming cultural exclusion. Field studies were undertaken in the UK, Ireland and Sweden based upon live projects with keyworkers who were subsequently interviewed about their roles, professional development needs and attitudes. In the UK, the Victoria & Albert Museum's keyworkers comprised youth workers, in Sweden they were traffic wardens and taxi drivers, and the Irish Museum of Modern Art worked with a group of elderly adults. From these studies, the research was able to articulate key recommendations for developing museum policy on keyworkers to enhance adult learning in and through museums.

Integrating mathematics,science, and technology: effects on students

Few studies have examined the student learning effects of integrating science with mathematics and technology. We compared a school that integrated mathematics, science and technology in grade 9 to a school in the same district that taught the three courses separately. The distinguishing feature of the integrating school was the reorganization of instruction in the three subjects to prepare students for seven group projects (involving a total of 25 h) that required the application of knowledge and skill that were shared by the three subjects, as well as learning outcomes that were unique to each. The study detected benefits for students in the integrated setting in terms of their ability to apply shared learning outcomes, student motivation, ability to work together and attitudes to appraisal of group work. Female students in the integrated school had a better understanding of selected science learning outcomes. Attitudes toward mid‐term exams were higher in the control school.

     

Learning in and beyond school gardens with cyber-physical systems

This design-based research study considers the learner-generated design and refinement of a school garden. We report one enactment of the Connected Gardening project in order to illuminate and understand how a fourth-grade class organizes and refines its garden plot using observations of the physical environment and evaluations of data from a networked digital probe. By examining the ways individuals, materials, and activities influence, and are influenced by, one another, our qualitative analysis characterizes interplay among an ecosystem, a garden and graphical representations of environmental indicators in real time and over time. We consider the novel affordances of such a cyber-physical systems for supporting participatory culture within yet beyond school classrooms.     

The role of design ethics in maintaining students' privacy: A call to action to learning designers in higher education

Maintaining students' privacy in higher education, an integral aspect of learning design and technology integration, is not only a matter of policy and law but also a matter of design ethics. Similar to faculty educators, learning designers in higher education play a vital role in maintaining students' privacy by designing learning experiences that rely on online technology integration. Like other professional designers, they need to care for the humans they design for by not producing designs that infringe on their privacy, thus, not causing harm. Recognizing that widely used instructional design models are silent on the topic and do not address ethical considerations such as privacy, we focus this paper on how design ethics can be leveraged by learning designers in higher education in a practical manner, illustrated through authentic examples. We highlight where the ethical responsibility of learning designers comes into the foreground when maintaining students' privacy and well-being, especially in online settings. We outline an existing ethical decision-making framework and show how learning designers can use it as a call to action to protect the students they design for, strengthening their ethical design capacity.

Practitioner notes

What is already known about this topic

• Existing codes of ethical standards from well-known learning design organizations call upon learning designers to protect students' privacy without clear guidance on how to do so.
• Design ethics within learning design is often discussed in abstract ways with principles that are difficult to apply.
• Most, if not all, design models that learning design professionals have learned are either silent on design ethics and/or do not consider ethics as a valid dimension, thus, making design ethics mostly excluded from learning design graduate programs.
• Practical means for engaging in ethical design practice are scarce in the field.

What this paper adds

• A call for learning designers in higher education to maintain and protect students' privacy and well-being, strengthening their ethical design capacity.
• A demonstration of how to use a practical ethical decision-making framework as a designerly tool in designing for learning to maintain and protect students' privacy and well-being.
• Authentic examples—in the form of vignettes—of ethical dilemmas/issues that learning designers in higher education could face, focused on students' privacy.
• Methods—using a practical ethical decision-making framework—for learning design professionals in higher education, grounded in the philosophy of designers as the guarantors of designs, to be employed to detect situations where students' privacy and best interests are at risk.
• A demonstration of how learning designers could make stellar design decisions in service to the students they design for and not to the priorities of other design stakeholders.

Implications for practice and/or policy

• Higher education programs/institutions that prepare/employ learning designers ought to treat the topics of the designer's responsibility and design ethics more explicitly and practically as one of the means to maintain and protect students' privacy, in addition to law and policies.
• Learning designers in higher education ought to hold a powerful position in their professional practice to maintain and protect students' privacy and well-being, as an important aspect of their ethical design responsibilities.
• Learning designers in higher education ought to adopt a design thinking mindset in order to protect students' privacy by (1) challenging ideas and assumptions regarding technology integration in general and (2) detecting what is known in User Experience (UX) design as “dark patterns” in online course design.
