Evaluating the Impact of Educational Technology Erno Lehtinen University of Turku Finland European Association for Research on Learning and Instruction (EARLI)
New challenges Managing complex, ill-defined problems Managing rapid change Continuous surpassing of existing expertise Learning socially shared and distributed expertise Effective use of cultural artifacts Traditional schooling Dealing with well-defined pieces of knowledge Conveying established traditions of knowledge Fulfilling external standards Cultivating individual minds Emphasis of pure mental operations New challenges of learning - are the schools prepared?
Self-evident benefits of information and communication technology • the power of multimedia • interactivity • possibilities for multiple representations • possibilities to simulate real phenomena • world wide access to information • tools for synchronous and asynchronous communication • How real are these (technology-driven) benefits?
Desires for using ICT to improve learning: Theory-driven arguments • Technology as inspiration for advancement of the theories and models of learning • applications of constructivist epistemology • new notions of collaborative learning • communities for progressive inquiry and knowledge building • authentic and anchored learning • from knowledge acquisition to participation metaphor of learning
Promises of ICT: results of the experimental research • Reviews and meta-analyses of more than 1500 experiments show that: • ICT students learn more • ICT supports social interaction • ICT improves student motivation but also causes motivational problems • the quality of learning depends on the type of ICT application
Promises of ICT: Experiences in the innovative projects • Higher order learning in traditional school tasks • complex problem solving • meta-cognitive skills • Results going beyond the aims of traditional education: • communities of distributed expertise • new media skills • active participation
ICT and the quality of learning in ordinary classrooms • A few very good spontaneous examples • Very much superficial quasi-activities • In many technologically well equipped schools ICT has only occasionally been applied in teaching and learning • Due to negative side effects many teachers do not use Internet
How to explain this contradiction between different results?
Critical reflection of the experimental evidence • Publication bias: only articles with positive effects are submitted and accepted • “Unfair” experimental designs • Anatomy of the experimental evidence • the size of experimental groups • the duration of experiments
Analysing the impact of ICT: methodological challenges • Why it is so difficult to measure the impact of ICT in education • Moving from ”traditional” to ICT environments: difficulties to define the ”independent variable” (systemic change) • In innovative use of ICT also the learning aims change
New methods are needed: Example CSCL • Collaboration around and through technology • Analysis of document structures • Content analysis of CSCL documents • Analysis of participation activity • Analysis of participation structures
Critical reflection of innovative projects • Marketing of scientific ideas and applications • Theoretical concepts have a tendency to turn into ideological slogans • Individual differences have been neglected • New ICT based environments change the motivational and social interpretations • virtual open learning environments are obviously increasing achievement differences between learners • Unrealistic investments in terms of preparation and support of the teaching
A scaling up problem: why ”best practices” do not transfer • Experimental evidence is partly misleading • selected teachers, major investments etc. • Shortage of realistic models • Shortage of ”killer applications”; ICT based practices able to solve the hard nuts of teaching and learning • Shortage of models for long term everyday use • Direct transfer of practices is not possible – a transformation an localisation is needed
Preparing students for information society and the responsibility of the educational systems • New literacy for all students – avoiding new inequality • Innovative use of new technologies to improve access to education and quality of learning – not fashionable application of virtual environments at the expense of quality
Stronger teacher involvement in the development of the ICT tools an practices: • Teachers must have ownership (eg. learning objects approach) • Innovative use of ICT is not a private business of isolated teachers but it emphasises the community nature of the schools • The use of ICT in education should not be fully commercialised but a coordinated public-private partnership is needed
The duration of the experiment • Effect sizes in experiments of different duration
