Merging remote laboratories and enquiry-based learning for STEM education

Practical learning activities are effective ways to increase the interest of students in Science, Technology, Engineering and Mathematics (STEM) topics. Attracting school students to STEM careers is a challenge in many parts of the world. Remote Access Laboratories (RAL) allow for offsite control of state-of-the-art science and technology experiments. Such learning activities, while mostly used in universities, can also provide additional learning opportunities in schools. Current RAL technologies are targeted at undergraduate engineering education and offer limited operational autonomy. Opportunities for collaboration and experiment design are not well supported. However, both are important components of STEM education in schools. This paper discusses how RAL can be adapted to better support enquiry based learning in the context of STEM education. The limitations of current architectures are discussed and approaches to address these are presented

Enabling peer-to-peer remote experimentation in distributed online remote laboratories

Remote Access Laboratories (RALs) are online platforms that allow human user interaction with physical instruments over the Internet. Usually RALs follow a client-server paradigm. Dedicated providers create and maintain experiments and corresponding educational content. In contrast, this dissertation focuses on a Peer-to-Peer (P2P) service model for RALs where users are encouraged to host experiments at their location. This approach can be seen as an example of an Internet of Things (IoT) system. A set of smart devices work together providing a cyber-physical interface for users to run experiments remotely via the Internet. The majority of traditional RAL learning activities focus on undergraduate education where hands-on experience such as building experiments, is not a major focus. In contrast this work is motivated by the need to improve Science, Technology, Engineering and Mathematics (STEM) education for school-aged children. Here physically constructing experiments forms a substantial part of the learning experience. In the proposed approach, experiments can be designed with relatively simple components such as LEGO Mindstorms or Arduinos. The user interface can be programed using SNAP!, a graphical programming tool. While the motivation for the work is educational in nature, this thesis focuses on the technical details of experiment control in an opportunistic distributed environment. P2P RAL aims to enable any two random participants in the system - one in the role of maker creating and hosting an experiment and one in the role of learner using the experiment - to establish a communication session during which the learner runs the remote experiment through the Internet without requiring a centralized experiment or service provider. The makers need to have support to create the experiment according to a common web based programing interface. Thus, the P2P approach of RALs requires an architecture that provides a set of heterogeneous tools which can be used by makers to create a wide variety of experiments. The core contribution of this dissertation is an automaton-based model (twin finite state automata) of the controller units and the controller interface of an experiment. This enables the creation of experiments based on a common platform, both in terms of software and hardware. This architecture enables further development of algorithms for evaluating and supporting the performance of users which is demonstrated through a number of algorithms. It can also ensure the safety of instruments with intelligent tools. The proposed network architecture for P2P RALs is designed to minimise latency to improve user satisfaction and learning experience. As experiment availability is limited for this approach of RALs, novel scheduling strategies are proposed. Each of these contributions has been validated through either simulations, e.g. in case of network architecture and scheduling, or test-bed implementations, in case of the intelligent tools. Three example experiments are discussed along with users' feedback on their experience of creating an experiment and using others’ experimental setup. The focus of the thesis is mainly on the design and hosting of experiments and ensuring user accessibility to them. The main contributions of this thesis are in regards to machine learning and data mining techniques applied to IoT systems in order to realize the P2P RALs system. This research has shown that a P2P architecture of RALs can provide a wide variety of experimental setups in a modular environment with high scalability. It can potentially enhance the user-learning experience while aiding the makers of experiments. It presents new aspects of learning analytics mechanisms to monitor and support users while running experiments, thus lending itself to further research. The proposed mathematical models are also applicable to other Internet of Things applications

Using gamification to create opportunities for engagement, collaboration and communication in a peer-to-peer environment for making and using remote access labs

The RALfie Project began in 2013 with the goal of engaging children and youth with Science, Technology, Engineering and Math learning in formal and informal settings using Remote Access Labs (RAL). A design based research approach is being used to develop and test a peer-to-peer system that incorporates gamification of the system to engage learners in collaboration and communication. The key game mechanics used are: Narrative with a group of characters who play key roles in the community; a maker approach where the participants build the RAL as opposed to expert-built rigs; communities of practice based on video game style `guilds'; tasks and activities designed as quests with opportunities for collaboration; and a reputation and achievement system to track mastery that uses points, levels and badges. An iterative approach is being used to test and refine the gamification elements and technical system that form the environment. This paper provides a summary of the theoretical educational foundations of this project; discusses design-based research as the methodology in the context of the RALfie project; and presents initial results. It includes design decisions and feedback from expert review

Teachers Support for English Language Learners to Build Inquiry Skills in Online Biology Simulations

The population of English language learners (ELLs) is on the rise in the United States, but they are lagging behind English speaking students in several subject areas--including biology. Scholarly literature lacks information on how biology teachers use scaffolding strategies to support ELL students with inquiry skills during online simulations. The purpose of this qualitative multiple-case study was to explore how biology teachers support ELLs in learning biology, using biology simulations to promote inquiry learning. The conceptual framework for this study included the constructivist perspective regarding the zone of proximal development, Electronic Quality of Inquiry Protocol, and technology use in science instruction. The purposive sample for this study was 4 biology teachers from 2 high schools in large school districts in the southeastern region of the United States who taught ELL students using inquiry-based online simulations. The data sources were face to face interviews with teachers, scaffolding documents, and lesson plans. Data were coded and analyzed for common themes across within and across cases. Results indicated that although biology teachers believed that ELL students benefited from inquiry simulations because of the already incorporated visuals and their ability to interact and manipulate the program, they sometimes lacked technology experiences and struggled with English and literacy that may reduce the benefits of the simulation experiences. The results of this study have the potential to contribute to social change by providing insights that may increase the understanding of how biology teachers can support ELL students when using technology in the form of simulations to promote inquiry learning

Astrobiology and Society in Europe Today

This book describes the state of astrobiology in Europe today and its relation to the European society at large. With contributions from authors in more than 20 countries and over 30 scientific institutions worldwide, the document illustrates the societal implications of astrobiology and the positive contribution that astrobiology can make to European society. The book has two main objectives: 1. It recommends the establishment of a European Astrobiology Institute (EAI) as an answer to a series of challenges relating to astrobiology but also European research, education, and society at large. 2. It also acknowledges the societal implications of astrobiology, and thus the role of the social sciences and humanities in optimizing the positive contribution that astrobiology can make to the lives of the people of Europe and the challenges they face

Using open ended, ill formed problems to develop and assess Engineering Mathematics competencies.

The purpose of this paper is to report upon how an engineering mathematics class was used to provide a vehicle for students to develop mathematical competencies and hence higher order thinking skills within the broader field of engineering education. Specifically it provided students with the opportunities to think mathematically, reason mathematically, pose and resolve mathematical problems, to use technology to model resolutions, interpret and handle mathematical symbolism and to communicate their resolutions to peers and staff. Using the report produced by the Mathematics Working Group of SEFI (European Society for Engineering Education), which details a framework for mathematics curricula in engineering education (SEFI, 2013), a methodology was identified. This methodology was also based on work previously undertaken by the author (Peters, 2017; Peters, 2015). In section 2.1 (p 13) the report lists and describes a set of eight mathematical competencies: (1) Thinking mathematically, (2) reasoning mathematically, (3) posing and solving mathematical problems, (4) modelling mathematically, (5) representing mathematical entities, (6) handling mathematical symbols and formalism, (7) communicating in, with, and about mathematics and, (8) making use of aids and tools. The report also points out the importance of developing assessment procedures pertinent to competency acquisition (p7). The evidence from this investigation concludes that the majority of students found the experience challenging but worthwhile. They considered they had learnt important skills including the ability to form assumptions, persistence, time management, project management and an enhancement of their mathematical skills in relation to engineering

Valuing diversity and establishing an approach to supporting excluded groups

Minority students and minority employees in Higher Engineering Education experience inequality. For academic staff these inequalities impact their personal development and career progression. To continue to grow and for engineering education to thrive as a professional discipline we must encourage diversity within both the student and staff populations. This paper cautions against a simple notion of diversity, rather a truly diverse culture within engineering is needed, one in which there is diversity of opportunity, diversity of thought and diversity of experience. To enable a more inclusive environment to flourish we must understand the scale of the inequalities which exist. However, this paper demonstrates that there are significant limitations to the current diversity data within the UK which leaves room for under-reporting and over-generalising. In addition, there are cultural challenges which give further likelihood to non-disclosure and lack of self-reporting. This paper proposes that further research is needed into the true lack of diversity within engineering and describes one example of a ‘thought experiment’ conducted by the researchers to start unpacking the data and highlighting the scale of the issue
