Building a successful 21 century education system.Ralph Springett
A successful 21st Century Education System needs careful consideration of the support, communications, and learning experiences you provide. With the introduction of education technologies the distance between the teacher and the learner grows and with it their relationship.
This presentation offers practical solutions relating to the levers that are available to institutions to strengthen learner engagement, provide authentic learning opportunities and understand how to challenge learners to develop their 21st century skills.
This workshop is part of the Media Education: Make It Happen! program, a series of free resources to help educators understand and facilitate media literacy in their classrooms. The program consists of a booklet, PowerPoint workshop, and a facilitator's guide with handouts.

European perspectives on design for learning in the 21 centuryTeemu Leinonen
Keynote at the National Conference about flexible learning, 15-17 July Wrest Point Conference Centre, Hobart, Tasmania, Australia / Australasian Association of Distance Education Schools.
In this address, Professor Leinonen will discuss ‘meta-design’, which means design of ‘things’ for educators to design their own teaching and for learners to design their own learning. He will also present a generic Finnish / Northern European perspective on ICT in education, which he and his colleagues aim to make a pan-European model through a project entitled Innovative Technologies for an Engaging Classroom (iTEC). iTEC is a four-year, large-scale project that takes an informed look the potential classrooms of the future. With 27 project partners, including 14 Ministries of Education and funding from the European Commission of 9.45 million Euros, iTEC will provide a model describing how the deployment of technology in support of innovative teaching and learning activities can move beyond small scale pilots and become embedded in all Europe's schools. iTEC is being piloted in over 1,000 classrooms in 12 countries, making it by the most significant pan-European validation of ICT in schools yet undertaken.

Teaching and Learning with Artificial IntelligenceTeemu Leinonen
Slides from a talk where I argue that when we teach and learn with artificial intelligence (AI), pedagogical choices matter. Artificial intelligence is also not the first technology to challenge education. This time, the biggest challenge is related to the assessment of learning. When we want to teach and learn (1) concepts, (2) problem-solving skills, (3) cultural literacy, (4) mathematic literacy, (5) logics and analytics thinking, (6) higher-level understanding, (7) ethics, and (8) civics, we should pay attention to (1) transparency and Code of Conduct, (2) project-based learning, (3) letting AI do the first version, (4) lecture notes, (5) project presentations and demos, (6) seminars, (7) viva voce exams.

The classical division of formal, non-formal and informal learning are challenged by mobile and IoT technologies connected to cloud computing applying artificial intelligence. With sensors and audio and video recordings we can track and record humans' and machines' activities that can be then analysed to automate routine tasks but also to provide information for reflection and conscious development of human activity. During my talk I will present and discuss the new possibilities of tracking and recording of actions in the context of new pedagogies for workplace learning.

Abstract:
Back in 1997 while working at Media Lab Helsinki, Finland my colleagues and I started a research project called Future Learning Environments. Our main partners were educational psychologists at the University of Helsinki. Soon after this we organized ourselves as the Learning Environments research group (LeGroup). The mission of the research group was (and still is) to explore ways to improve the quality of teaching and learning with smart technological solutions. From the very beginning our research focused on the use of mobile devices, with the idea of bringing learning to meaningful contexts, and to support learners' knowledge building and reflective activities. The tools designed and developed, as part of our research, have helped students to develop their self-regulation, a skill closely related to students' well-being, to forms of deep learning and to autonomy. With our research we have not been driven by the common attempt to save time and money, instead we have aimed to abilities to innovate and to create social change.
During my talk I will make a retrospective journey through some of our work, starting with some early experiments in computer supported collaborative learning (CSCL) with school children using Nokia Communicators (1997) and Nokia Internet Tablets (2005). I will also introduce some of our research on educational challenges in the Global South that made use of the affordances of basic mobile phones for knowledge sharing (2003-2005). Furthermore I will discuss our more recent work on mobile learning research dealing with the role of mobile devices in reflective and self-regulated learning, an augmented-reality application for workplace learning and on the challenges and possibilities of using biometric measures along wearable computers for collecting data for learning analytics. Through this journey, I aim thus to outline a few signposts of the past and present of mobile learning research, design and development. My hope is to help us discuss the future of education and the future tools to be designed when most things and activities in our life are digitally enhanced and networked.

Critical aspects of digital tools in learning processes during the near futureTeemu Leinonen
“We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run.” Roy Amara. Therefore we may predict or at least get an idea on what will happen next by closely following the technology development and by having a active role in it. The design and development of digital tools for learning or tools in general that are adapted to teaching and learning is not unproblematic. The three mega trends in technology; (1) Internet-based networks, (2) growing computing capacity and (3) automatization and robotics are providing new pedagogical and societal opportunities but also new challenges. The most interesting research themes related to the digital learning tools are the future of formal and informal learning, virtual social environments and analytics and adaptation. Working with the themes as a design researcher and designer one should be highly aware of the possible ethical issues related to these. To analyze the impact, positive and negative, we can use so called McLuhan’s Laws of Media, four questions we present to new media / tools.
The slides are from the teaching demonstration 20.9.2016. A lecture and exercise designed for the DOM-E5024 Introduction to Media Art and Culture course.
Guiding Students to Become Lifelong Learners: Flipped Classroom and Meaningfu...Teemu Leinonen
In this article we present a good practice of combining several teaching strategies such as blended learning, the flipped classroom and self-directed study activities in a MA level course, with the aim of helping students develop lifelong learning skills. We report how we adopted the flipped classroom model in several editions of the Introduction to Media Art and Theory course through the organization of fishbowl discussions with the students about the homework assignments they were asked to prepare before the classes. The course final assignments consisted in a video essay that the students had to produce in small groups and present to the class. The video essay required students to do research, define a research question and develop a critical attitude towards the topics explored. We analyzed the students’ feedback as well as the video essays submitted by the students in order to assess if the course provided them a meaningful learning experience and if it helped them become lifelong learners. We conclude that the course achieved the intended goals and that it represents a valuable case to discuss among the educational community.

Teemaseminaarin kuvaus: "Tässä teemasessiossa otetaan MOOCista mittaa. Maailman johtavat yliopistot, Stanford, MIT ja monet muut ovat alkaneet massiivisesti tuottamaan kursseja MOOC ympäristöön.
Mitä, miten, miksi? Tarjoaako MOOCsit tulevaisuuden näkymän globaliin koulutustarjontaan ja miten siihen vastaavat suomalaiset koulutuslaitokset?
Millaisia kokemuksia on MOOCsien käytöstä niin tutkimuksen kuin käyttäjien kertomana?
MOOCsien yhteydessä on paljon esillä oppimisanalytiikka eli miten käyttäjätietoja voidaan hyödyntää, oppijan, opettajan ja kurssien suunnittelijan tukena? Avaako oppimisanalytiikka uusia pedagogisia näkymiä?
Virtuaaliyliopistot tulivat 90-luvun puolivälissä ja hävisivät reilu 10 vuotta myöhemmin. Ovatko MOOCit vain tähdenlento vai pysyvämpi ilmiö ja muutoksen aiheuttaja?

In-Time On-Place Learning — Creation, Annotation and Sharing of Location-Base...Teemu Leinonen
Presentation in the 10th International Conference on Mobile Learning 2014, 28 February – 2 March, Madrid, Spain. The aim of the research is to look at how mobile video recording devices could support learning related to physical practices or places and situations at work. The paper discusses particular kind of workplace learning, namely learning using short video clips that are related to physical environment and tasks preformed in situ. The paper presents challenges of supporting learning as part of work practices taking place in the workplace, because learning has different attributes during work than in formal educational contexts: e.g. it is informal, just in time and social. The theoretical framework of the design is the tradition of pragmatism. We start with the concepts of experience, change of practices / habits and reflection, claiming that living through experiences suggest changes for practices and these trigger reflective processing of the situations. We present an Android application ‘Ach So!’ for creating and annotating short videos as potential solution for informal learning for physical work practices. The paper ends in proposing future steps in the development of the application. The co-design process for the application is lean and iterative, where the design receives feedback from the project partners, skilled workers, apprentices and managers of SMEs targeted to be the main users of the application.
Blended learning in higher education: Theory and practice in FinlandTeemu Leinonen
Educational methods, pedagogy and technology used for teaching and learning, is changing. The fact that the price of communication and to deliver information is becoming close to zero requires educators to reconsider their practices.
Higher education relying only to classical lectures is coming to the end. The "digital first" approach, where all learning materials and large part of course communication such as announcements and assignments, in addition to administrative tasks, is brought to the open web will force us to reconsider how to make the classroom situations more valuable for students.
By introducing flipped classroom approach and study projects we can implement problem based learning and progressive inquiry where students are asked to to research in small groups. In introduction courses we can give for students homework, asking them to read and watch video lectures, and then use the classroom time to discuss about the content. In study projects the small group research should take place in an authentic research environments with more advantages researchers, in labs and studios where the expert work. This way students will have access to the tacit expert knowledge. On the other hand, there is a need to learn skills that will help to work in multidisciplinary groups. Essential is to learn to understand other competences — to respect them and to get excited about them. Therefore part of the studies should take place in multidisciplinary study projects focusing on to solve the real world problems.
In this slide set I start by introducing some sides of Finland and the Aalto University. I continue with a short presentation of pedagogical ideas that aim to be relevant in the network society. I conclude with the "digital first" statement and present some examples from my own courses, as well as of the latest digital tools developed as part of the research in my research group.
