Issue: The Online Assessment of Technology Literacy The Online Assessment of K-12 Technology Literacy As our society grapples with rapid technological change, assessing technology literacy has emerged as a K-12 educational issue. The No Child Left Behind Act specifies as a goal that every child will be technologically literate by the end of the eighth grade, business pleads for a workforce that can use information and communications technology (ICT), and the education community itself recognizes the importance of establishing a foundation for lifelong learning. The Institute for the Advancement of Emerging Technologies in Education (IAETE) at Edvantia, Inc. (formerly AEL) addressed the need to assess technology literacy in an e-mail-based panel held during one week in September 2005. (Further exploration of this topic can be found in companion articles in IAETE's online publication, InSight, at www.edvantia.org/insight/1 ). The conversation began with the importance of defining technology literacy, identifying a range of definitions rather than precise limits. There was, however, consensus that ICT literacywhich can be viewed as one component of technological literacyimplies both basic computer skills and the cognitive abilities associated with using those tools for learning and communication. The panelists then turned to the emerging possibilities for assessing via simulation, the new design processes needed for any computer-based assessment, and the lack of research to assist assessment developers in this new territory. Mary Axelson moderated the following panel members:
Defining Technology In the interest of complete honesty, the Academies are far from the first to describe and promote this larger view of technology. Philosophers of technology such as Langdon Winner, historians of technology like Thomas Hughes, and technology critics like Neil Postman have all taken this larger view. So has the STS (science, technology, and society) movement in U.S. postsecondary education, and the International Technology Education Association, which represents technology education teachers in this country.No matter the definition, people working in a K-12 environment make ICT their priority. Writes Honey, In contrast to Greg, I'm choosing to highlight a set of fairly specific skills and competencies that students need. I don't by any means disagree with GregI like the breadth of his argument and ideas. I'm motivated to write more specifically only because I see too much of what is NOT being taught in schools. In too many schools we are stuck with a very 1980s notion of technology competencya kind of basic facts approach to technologythat's not serving our kids well.Kemker, too, sees a pressing need to establish a foundation of computer skills. In Florida, for example, the state hopes to put its high-stakes test online, and an inventory of student computer skills could help ensure that the computer-based format does not hinder student performance. However, she's also wary of the momentum stopping there: The discussion from my perspective is, do you measure all of these skills at once with a performance-based solution within scenario-based settings? Or do you begin with basic computer skills, then communication, basically in a hierarchal method? The situation that we face in K-12 education is that if we begin with one area then precedence has been established in which those skills tend to have greater value than the other skills.
Defining Literacy as Higher Order Thinking Though there was not wide agreement on the scope of the word technology, all panelists did share an understanding of literacy as something significantly beyond basic skills. Ripley has a particular interest in the higher order thinking that high-tech tools make possible. Observing that schools now focus more on developing student computer skills to support learning across curricula rather than studying about computers, Ripley asks, So, can we usefully ponder what subject will replace IT, and why? My view is that the subject must change its outlook from training students predominantly in the skills and capabilities that arise from the existence of personal computers. Instead we should look for the subject IT to concern itself increasingly with the growing range of technologies (mobile devices, blogs, video). It should concern itself with the uses to which technology is put (work, leisure, recreation, purchase). And it should concern itself with the facilities (or capabilities) that those technologies provide to students and adults (voice, visual communication, decision making, choice, responsibility).After quoting a job description for an engineer at Boeing (and safely assuming education prepares people for jobs), Ripley summarizes, "In other words, we must expect technology to help our students to be 'flexible' and to be 'curious.'" Pearson's reports identify "three interdependent dimensions" of technological literacy: knowledge, capability, and ways of thinking and acting. Pearson notes that the capability dimension relates to abilities that may be easier to assess. According to Pearson, the committee noted that a "technologically literate person would
Honey observes that students today have almost universal access to unfiltered and unsubstantiated information. No longer do they receive their information solely from teachers or librarians, or through textbooks or print-based reference materials. She continues,
To navigate through this wealth (or glut) of data, draw conclusions, and communicate with others proficiently, teachers and students require whole new sets of skills surrounding accessing, interpreting, analyzing and evaluating complex sets of images, words, numbers and sounds in meaningful ways.
She identified some of these skills as communicating effectively, analyzing and interpreting data, understanding models and simulations (computational literacy), managing and prioritizing tasks, engaging in problem solving, and ensuring security and safety. Her work with the Partnership for 21st Century Skills identifies ICT learning skills as related to thinking and problem-solving skills, information and communication skills, and interpersonal and self-direction skills. Honey and the Partnership emphasize that these skills are a priority and can be addressed through core subjects as well as in areas they refer to as 21st Century Content: global awareness; financial, economic, and business literacy; and civic literacy. ICT learning skills are interwoven with technology because their pursuit is so often assisted by high-tech tools.
The Promise of Simulation-Based Assessment
The use of simulations is a key development. A simulator provides the context within which authentic assessment tasks can be designed and delivered to students. It also facilitates the development of assessment tasks that invite students to combine a range of capabilities and skills. The combination of these two aspects enables us to assess higher order IT capabilities, such as choice or communication.Simulation, of course, is not the only possible method to assess technology literacy. As Pearson points out, "I first will disagree slightly with Mary's contention that assessment of higher-order thinking requires 'new' assessments. Assessments that get at the more complex aspects of student thinking already existin instruments that creatively use extended and open-ended response items, and in some portfolio techniques." He points to an assessment of design capability by the International Baccalaureate as an example. And Pearson observes that while portfolio assessments are often viewed as limited in terms of providing valid and reliable data in a high-stakes arena, they could face fewer problems "if the rubrics for evaluating them are carefully thought through and teachers/evaluators are trained on the rubrics' use." Honey's report also identifies an array of assessments for the 21st Century Skills other than ICT literacy. Working with a New Design Process Should one wish to pursue simulation or other computer-based simulations, such as virtual environments or multiplayer, role-playing applications, both Ripley and Kemker forewarn that the entire design process changes. Writes Ripley, In every e-test development project I have worked on it is possible to get all of the senior staff (designers, technologists, psychometricians, trainers, teachers) together regularly. These core teams number around 15-20 individuals and can be led effectively as a single team. There is no parallel in my experience with paper-based tests, which are often developed in a linear process, with different teams (involving large numbers of people) responsible for the various stages of development, administration and marking.Kemker, too, describes such team. Echoing advice given at an earlier IAETE symposium2, she focuses on the importance of the project manager. The development of online assessments requires a very diverse team of individuals. It is imperative that each member of the team be an expert in specific fields, such as measurement, technology, and curriculum. Last year, as we developed the online assessment tool for teacher technology skills, the team consisted of these individuals in addition to teachers.In Kemker's experience, bringing technologists and assessment experts together sparked a great deal of creativity and discussions of new possibilities for assessment. Ripley, however, lamented the lack of creativity from technologists. "The concepts, the ideas, the vision have come predominantly from the assessment experts and teachers. The quest for technology solutions to the many complex measurement problems and barriers has come from the assessment experts." Ripley also cautions that change must go beyond the design group. The types of tests his work group designs pose problems beyond the "once correct answer" paradigm that dominates assessments for accountability purposes. He writes, Assessments which use simulations are a radical development. Delivering high-stakes assessments to all schools onscreen is a departure from current practice. This type of test development project involves systemic, nationwide innovation and change. The nature and extent of innovation in this type of redesign challenges psychometric expertise and wisdom; it requires teachers to adapt their teaching, and it requires pupils to reconsider ideas of what tests involve; it requires a national school hardware infrastructure that is as robust as some international banking systems; it requires network managers and technical staff in schools who can support the system. So, this is what I mean by 'systemic innovation.'Establishing a Research Base Ripley's comment above, "The nature and extent of innovation in this type of redesign challenges psychometric expertise and wisdom," is a reference to the lack of research on the validity or reliability of assessment via simulation. Pointing out the increasing presence of simulation for instruction, Pearson observes that "the use of simulation in educational assessment probably requires quite a bit more study before it can be used with confidence. The assessment literature is mostly silent on simulation and essential psychometric issues such as reliability, validity, and precision." Ripley suggests the need for research on all computer-based testing: Greg has elsewhere made a good point about the general lack of psychometric research and empirically based evidence to support the most adventurous forms of e-test development. I see that deficiency in almost all aspects of e-test development . . . . In England I like to remind colleagues that paper-based testing has been in use for 140 years. The science and business of paper-based testing is well refined and well evidenced. A person experienced in managing, researching or administering one set of paper-based tests is likely to be able to move in a straightforward way to a similar role in relation to other paper-based tests. In contrast, there is little stability yet in e-testing. The business processes are immature. Even when the e-test consists of closed-response or multi-choice items, the on-screen delivery involves making design decisions on the basis of emergent thinking, not on industry best practice standards (which do not yet exist).
Ripley advises that research focus on "sources of difficulty" (the full range of demands carried by a test, but not part of the targeted assessment domain), the validity and reliability of measurement methods used in simulation-based assessments, and the possibilities of expanding it to domains beyond ICT. Assessment designers would benefit from having more information about such issues as expert/novice differences in knowledge acquisition, concept formation, misconceptions, and knowledge transfer, just to name some of the most obvious areas. A better understanding of these very fundamental aspects of learning will greatly improve the quality of assessment for technological literacy, as well as the potential to harness simulation effectively.Panelists also identified issues beyond the functionality of the test format. For Pearson, technological literacy includes the ability to weigh the risks and benefits of new technologies, and he applies that to simulation-based assessment: I would like to ask my colleagues whether they feel students and teachers should, in addition to simply using ICT as a learning tool, also be challenged to think about and discuss ICT in a somewhat more critical way. For example, what are some of the unintended consequences of our use of computers in education? What trade-offs are we making, intentionally or not, by placing ICT in such a prominent position in U.S. education?In response, Ripley shifts the critical eye from technological priorities to assessments. He writes, The difficulty and challenge in focusing our technology ambitions on assessment is that assessment is such a blunt instrument. National assessments are filled with unintended consequences. They atrophy and become predictable within a matter of a couple of years, with the result that creativity and innovation are lost. And the processes of preparing students for high stakes national assessments are rarely witnesses of exemplary pedagogy. 1InSight, 2005 2On Formative, online assessment
