LSC 555 Blog #3 – First Principles of Interaction Design

Bruce Tognazzini’s article, “First Principles of Interaction Design,” looks at design principles for effective graphical user interfaces (GUI) for web applications and mobile devise apps. The article, highlighting its own usability, is also available in Belorussian, German, Italian, Polish, Portuguese and Spanish, in addition to English.  

The author provides a quick summary.  Effective interfaces are apparent and instill a sense of control in the user, does not get the user involved in inner workings of the system, and perform maximum work with minimum information required from users.

The rest of the is, in effect, a working glossary of terms related to interaction and interface design.  If my highlighting is an indication of anything, the highest density of highlighted sentences exist under the following terms: autonomy (task environment “belongs” to the user); efficiency of the user (focus on user, not system productivity); explorable interfaces (user provided with established routes, allowed to proceed at their own pace); latency reduction (latency, the time lag resulting from performance of a certain action, is pushed to the background); and visible navigation (avoid “invisible” navigation between websites and internet spaces) (Toganazzini, 2003).

LSC 555 Blog #3 Usability of digital libraries

Ferreira and Pithan’s “Usability of digital libraries: a study based on the areas of information science and human-computer-interaction” provides an informative overview of human-computer interaction concept while presenting the results of carefully designed research on the usability of digital libraries.   The specific digital library under study is the Brazilian Infohab digital library, an information and reference center on housing in Brazil.  The study seeks to integrate Kuhlthau’s constructivism with Nielsen’s thoughts on usability (Ferreira &Neilsen 2005).

The literature review section expands Neilsen’s five components for determining the usability of an information system, learnability, efficiency, memorability, errors and satisfaction.  In the section, User’s study, the authors focus on Kuhlthau’s constructivism (now familiar to us from reviewing it in 553 and 664), drilling down on affective (feelings) and cognitive (thinking) states in the information seeking process (ISP) that occurs as learners process new information.

The research method and data analysis sections are fairly standard.  I noted that it appears the Brazilians are in step with the Americans, if not several strides ahead, in designing studies on usability and human-computer interactions and I look forward to checking out some original research material in Portuguese, my second language.   The study and its results provide a timely introduction to as well as a companion piece for articles in the next section on interaction design principles.

Constructivism, Accountable Talk, Conversation Theory, and Information Literacy Instruction

Introduction

            This paper sets forth constructivism and a constructive approach as the best solution for information literacy instruction.  Many have already made that argument and made it convincingly.  What is different in this paper is my attempt to make the case that using deliberative discourse, also called accountable talk (pioneered at University of Pittsburg), is an excellent way to move forward the constructivist paradigm for learning.   Briefly, I will put a sharper point on the case I have made with a review of Pask’s conversation theory, and its latest disciple, David Lankes.  Finally, I will use two examples not related to information literacy instruction to illustrate the potential comprehensiveness of this approach.

A Constructivist Approach

Cooperstein and Kocevar-Weidinger (2003) convincingly explain the generally agreed upon elements of constructivist learning, i.e., learners “construct” meaning by making a deliberate attempt at sense-making of incoming information; learners “build” new information on top of old information, finding connections between the two; learners share and compare ideas and learn through the resolution of conflicting ideas; and learning happens through classroom activities that imitate and emulate activities in the real world (Cooperstein & Kocevar, p. 142).  The first two elements operate inside the learner and occur inside the mind.  Of the second two elements, the third is more socially oriented, i.e., accomplished through interactions with others, and thus, within our power to control, and the fourth is pretty much dependent on the strength and creativity of the teacher or instructor.  My focus, then, is on the third element.

Vygotsky (1966) describes how a child reaches his hand out to grasp an object that he sees but that is beyond his reach.  That reaching appears to surrounding people to be a pointing, though it may not be, it may just be a hand “hanging in the air.”  But the nature of the thing changes, from being an extended reach, to becoming a signal to surrounding people.  Vygotsky says the “child is the last to realize his own gesture” and concludes that “we become ourselves through others” (Vygotsky, p. 39).  This begins a very social way of interacting with and learning from others.  Expanded, Cooperstein and Kocevar-Weidinger claim that “an important aspect of constructivism is the need for social interaction” and that “group activity increases discussion, experimentation, enthusiasm, and participation (Cooperstein and Kocevar-Weidinger, p. 144).”

Constructivism works well in information literacy instruction settings for several reasons.  Grassian (2009) explains that the cognitive/constructivist model helps the learner “own” the material through active involvement, emphasizes collaborative learning, and allows for differing hypotheses that encourages development of a learning community (Grassian, p. 50-51).  Information literacy skills, like conducting searches or evaluating web documents, all lend themselves to learning that depends on cognitive activity, on thinking about discrete steps in a process, on brainstorming trial answers to a series of questions, and on sharing and comparing those trial answers to discover the best outcome or the most satisfactory information solution.

Accountable Talk/Deliberative Discourse

Accountable Talk, a conversation methodology pioneered at the University of Pittsburg, focuses on establishing group norms that simultaneously support rigorous inquiry and promote equity and access (Michaels, O’Connor & Resnick, 2007).  Most experiments in Accountable Talk have occurred with children, but information literacy instruction groups at high school or college age would make a good experimentation model.  The authors at Pitt developed Accountable Talk from a Vygotskian theoretical framework emphasizing the importance of social interaction in developing thought processes that raise the level of discourse (Michaels, O’Connor & Resnick, p. 285).  By asking for clarification, through polite challenges, and by encouraging participation by all participants, the conversation itself spurs students to think more deeply, more carefully and more critically.

The “accountable” of Accountable Talk refers to levels or areas of accountability to which students (participants) are held.  While involved in conversations, students are held accountable to the learning community of which each is a part.  They must listen to each other, both to show respect, and to carefully assess what is being said so they can use and build on it.  Students are held accountable to accurate knowledge, i.e., they are responsible for their claims’ accuracy and truth.  Finally, students are held responsible to standards of rigorous and critical thinking.   These levels of accountability, along with the other group norms, would combine together to create a rich and creative environment for students in an interdisciplinary information literacy course.

Conversation Theory

Conversation Theory is in large part an extension and an amplification of Accountable Talk, although it predates Accountable Talk.  At the least, both derive from similar roots in the Vygotskian approach mentioned earlier in this paper.  Gordon Pask first developed it.  I will present below David Lankes’ moderated interpretation.

Lankes (2011) says a conversation has four parts: conversants, either people, or political parties, or even countries; a language, a set of meanings going back and forth; agreements, shared understandings between the conversants, arrived at through the language; and an entailment mesh, a collection and relation of the agreements (Lankes, p. 221).  Conversation may begin in a basic way, as a series of directions or instructions, simple exchanges.  One conversant may be a lot less knowledgeable than the other, but the exchange of these basic instructional directions builds a shared framework of common understanding.  Gordon Pask identified this stage as the initial stage of conversation (Lankes, p. 221).  After numerous exchanges at this level, if one of the conversants makes assertions that the other must agree to, over several iterations several agreements (or agreements not to agree) will be established, which may spawn different conversations.  This would be the second level (Lankes, p. 221).  Both conversants are now involved in learning, about each other, about their respective tastes and preferences and interests. Third level (Lankes, p. 222).  Once a collection of these agreements is established and stored in a memory file or a book, it will achieve what Pask and Lankes would call the fourth level, or entailment mesh (Lankes, p. 222).   At each level, new knowledge and new information are being formed and developed, in a constructivist way.

Conclusion

Last year I took a MOOC (Massive Open Online Course), Modern and Contemporary American Poetry, also called ModPo.  There were over 40,000 students in the course.  It was hosted by University of Pennsylvania, and live webcasts were broadcasted once a week, to which all participants were invited.  The professor used a team-teaching approach, and several videos each week featured close reads of poems with the professor at a table conversing with six teaching assistants.  The conversation was led by various team members at various times.  Each lecture was a conversation between the seven of them, piped out to over 40,000 students around the world.  The course was a grand success.  We learned the material, and a large percentage actually got certificates of completion.  In Washington, a dozen or so of us formed a weekly study group that met on Sundays at Politics and Prose Bookstore.  This year the course is being taught with the addition of some twenty community teaching assistants, embedded throughout the population of online students.  Perhaps such a model of conversation- and team-led instruction might be conceivable for information literacy instruction on a smaller level.

The final example is an information interview I conducted with Max McClellan, one of the producers of the highly regarded, award-winning news program, 60 Minutes.  One thing that the producer said made a very strong impression on me.  He said all interviews on 60 Minutes are conversations, the kind of conversation that anyone could imagine having in his/her own living room.  He said it was through conversations, going back and forth, that new information was developed, and it was through conversation that new knowledge was best imparted (M. McClellan, personal communication, August 16, 2013).

Both examples highlight the use of conversation as an instructional vehicle/mechanism.  Information literacy instruction might be ripe for the inclusion of more talk in the various methodologies already in use to convey and impart knowledge.

Institutional Repositories, Wikileaks, and the Network Age


Institutional Repositories, Wikileaks, and the Network Age

Introduction

In this paper, I will first define institutional repositories and evaluate and assess how diplomatic information, correspondence, and memoranda might fit into that definition.  Then I will trace the evolution of the mandate within our government to increase sharing of information across agencies, precipitated by the recommendations of the 9-11 Commission Report.  Just briefly I will mention society’s transformation from the Information Age to the Network Age and its impact on information sharing.  Following a short review of selected elements of forensics in digital librarianship, I will hypothesize how all these forces converged, resulting in the Wikileaks release of sensitive, classified information to public media outlets.  I will conclude with thoughts about the public interest and information governance within the framework of access to government information.

Institutional repositories defined

Institutional repositories, defined generically by Crow (2002) as “digital collections that provide access to the intellectual output of an institutional community,” is a term seldom applied to the extensive information holdings of a nation’s foreign affairs and national security superstructure.  But let us face the facts.  First, the Department of State, one foreign affairs agency among many, receives thousands of classified reporting cables per month originating from embassies and consulates throughout the world, distributed to U.S. embassies in nearby countries with a need to know, disseminated throughout the foreign affairs establishment in Washington and, in many cases, shared with close foreign allies.  Second, hundreds of thousands of government historical documents, diplomatic telegrams, memoranda, etc., are maintained in chronological order for ultimate de-classification and/or for distribution to the public upon request under the Freedom of Information Act.  Third, the Department of State Ralph Bunche Library, the oldest library in the Federal Depository Library system, (established by then Secretary of State Thomas Jefferson in 1789) holds 400,000 print volumes and several thousand e-books, along with access to numerous electronic databases (http://fdlp.gov/home/repository/doc_view/2167-us-state-department).

Yeates (2003) provides a similarly applicable definition of institutional repository.  “An institutional repository is the collective intellectual output of an institution recorded in a form that can be preserved and exploited…repositories are key to the ability of institutions to respond to future needs for more dynamic cross-boundary communications services” (Yeates, 2003).  One important drawback of institutional repositories cited by Yeates is reliance on unproven methods for long term digital preservation.  We will come back to that later.

One may conclude, then, that while not commonly considered as such (in large part, I suspect, because most often institutional repositories are considered in the academic environment exclusively), the extensive information holdings of the Department of State (DOS) may and should qualify as an institutional repository.  Moreover, it is not without precedent that a non-academic organizational body would adopt the institutional repository designation, especially if attached directly to a research-type institution.  As one example, Romary and Armbruster describe a decision by the European Commission, in conjunction with the European Research Council, to create an institutional repository (Romary & Armbruster, 2010).

9-11 Commission mandates information sharing

Chapter 13 of the 9-11 Commission Report calls for a different way of organizing government in wake of the terrorist attack on New York City (Kean, 2011).  Specifically, it cites information sharing failures that may have prevented analysts and intelligence specialists from “connecting the dots” in advance and thereby averting the terrorist attack.  Various pieces of information, for example, about the attackers and about their presence in the United States existed in various databases, for our purposes, in various institutional repositories across government, but the information was not shared across agencies.  The report made the following two recommendations:

Information procedures should provide incentives for sharing, to restore a better   balance between security and shared knowledge,” and

            “The president should lead the government-wide effort to bring the major national security institutions into the information revolution.  He should coordinate the resolution of the legal, policy, and technical issues across agencies to create a “trusted information network.

Agencies, including the DOS and the Department of Defense (DOD), in response to these recommendations, immediately sought ways, technologies, and methodologies to achieve the recommended intra-government information sharing that had previously been non-existent at worst and insufficient at best.  While the Ashcroft memorandum, released immediately after the 9/11 attack, was a knee-jerk response designed to restrict public access to sensitive information (Uhl, 2004), bi-annual GAO reports track steps taken within government to improve information sharing across agencies (Walker, 2004).  And as in most cases involving government bureaucracy, efforts and responses occur in a sporadic and uneven fashion.

SIPRnet opens the door to information sharing

The Secret Internet Protocol Router Network, also known as SIPRnet, had been known in military circles as the way the DOD distributed sensitive information on its various computer systems (Weinberger, 2010).  Largely in response to the recommendations of the 9-11 Commission Report, access to SIPRnet was expanded to include more members of the military, the intelligence community and overseas-stationed employees and contractors of DOD, DHS, and DOS.  BBC reported that at the time of the Wikileaks theft, over 2.5 million civilian and military members had access to SIPRnet (BBC, 2010).  Meanwhile, State developed its own repository of diplomatic communications, called the Netcentric Diplomacy Initiative, which allowed the sharing of its documents with and the hosting of its documents on SIPRnet.  Connection to and sharing with SIPRnet in effect expanded the size State’s institutional repository by a logarithmic proportion.  At this point, military members with access to SIPRnet also had open access to tens of thousands of diplomatic telegrams from U.S. embassies around the world.  To date, as a response to the Wikileaks release of classified telegrams, State’s Netcentric Diplomacy Initiative has suspended its access to DOD’s SIPRnet (Hoover, 2012).  State plans to have in place sometime in 2014 a metadata tagging system that will allow cataloging and retrieval of data from its vast repository of diplomatic telegrams but that capability does not exist at present.

Simultaneously, the big intra-governmental push to share information also harkened the requirement for government to “join the information revolution” (Kean, 2011).  However, by the time of the attacks of 9/11, social theorists had already postulated one year previously the transference from the information age to the network age, “one which goes beyond primarily content in the form of data to also embrace distribution infrastructure, data management and the linkages between content producers and consumers” (Brevini, Hintz, & McCurdy, 2013).   The idea of the network society also speaks to the role of the institutional repository in the evolution of government information systems.  While the Information Age gave rise to new ways of information generation, managing and dissemination through the use of new technologies (Paul, 2012), the Network Age broke the great power and sovereign state monopolies on information of the prior Information Age through the creation of media and social networks with expanded power and reach (Brevini, Hintz,& McCurdy, p. 89).  There also appears to be a correlation between the evolution from Information Age to Network Age and the evolution of Web consumers and downloaders in Web 1.0, to Web producers and uploaders in Web 2.0.

Digital decay opens the door to leakages

This information-rich environment might have remained the exclusive domain of trusted military and diplomatic operators.  Data security measures in place and information security (INFOSEC) incentives might have been sufficient to regulate control of sensitive material.  But there was one unplanned-for element, unanticipated digital decay.

Again, the language and vocabulary of institutional repositories holds explanatory power.  Long term preservation of digital information seems a foregone conclusion.  We believe that electronic data will remain, will retain its format, and will always be there in storage to serve us, like hieroglyphs carved on the walls of ancient Egyptian temple ruins.  Robert Fox (2011), in “Forensics of digital librarianship,” disabuses us of false notions of digital permanence by explaining causes of digital decay, some of which are quite relevant to the present discussion (Fox, 2011).  Enumerating possible causes of digital decay, Fox considers the following: neglect, where improper handling or exposure degrades media quality; file glut, where files are securely stored but in a disorganized or not well thought out manner, making it nearly impossible to retrieve relevant digital data; corruption, where flipped data bits, failure of storage systems, and human error lead to file corruption; hardware failure, disasters, backup failures, disc failures, and human error result in data loss; and obsolete formats, where obsolescence results from proprietary formats, defunct vendors, formats requiring special, obsolete hardware and/or obsolete storage media (Fox, p. 266).  Most significant among these causes of digital decay, and most relevant to our discussion of the Wikileaks release to public media of classified data, is the concept of file glut. In the case of Wikileaks, file glut didn’t specifically corrupt the records and the data, but it corrupted the process by which records were retrieved and transported to the degree that a low ranking soldier was able to burn copies of sensitive and classified material to DVD’s without his supervisor or anyone in his chain of command taking notice.

Summary and conclusions

The elements in place were the following: a foreign affairs agency with an institutional repository that doesn’t call it one; a mandate, following a vicious terrorist attack, to share information across agencies; the transformation from the Information Age to the Network Age that expanded the power and reach of social and media networks beyond and outside the power of the sovereign state; and file glut, resulting in decay of digital material due to improper organization of digital files and subsequent poor supervision of the process of retrieving and copying highly classified documents.  The question is less of why did Wikileaks happen when it did, and more of why something like Wikileaks didn’t happen sooner and/or why it hasn’t happened again?

We cannot have a discussion about government information without a discussion about transparency, the public interest, and the public’s right to know or have access to information that affects them, in short, that provides for an informed public which is necessary in a democracy.  In the United States, the right of the public to information about their government is enshrined in the Constitution and the nation’s laws.  The Freedom of Information Act, enacted in 1966, was the first federal law that established the legal right of access to government information (Uhl, 2004).  Unfortunately, the Ashcroft memo immediately following the 9-11 attacks not only curtailed access to information, but strengthened the government’s ability to restrict access and gave a blanket FOIA exemption to the newly formed Department of Homeland Security (Uhl, pp. 267-269).  There has been, arguably, a constant erosion of FOIA enforcement since the 9-11 attacks.  Insofar as the repository in question is a repository for the American people, this restriction on access is a negative.  But perhaps it is a repository not for the American people, but exclusively for the practitioners of foreign policy.  In that case, the public access restriction is a different thing altogether.  We have to define the stakeholders.

Who are the stakeholders in this information repository? And who are the shareholders? In other words, who has the greatest right to the information resources managed by government agencies, the government itself, or the people who elect and are represented by their government leaders?  Embedded in that question is an equally interesting one: who within government has the greatest, or strongest claim on information resources created and developed by government agencies, the executive or the legislative leadership?  It all comes down, basically, to a question of information governance and management of the information transaction space.  Kooper, Maes and Lindgreen (2011) describe information governance as “focusing on the seeking and finding, creation and use, and the exchange of information, not solely on its production,” and they view information governance as “a framework to optimize the value of information in some sense to the actors involved” (Kooper, Maes & Lingreen, 2011).   They describe the actors involved as 1) the creator of the information, 2) the receiver of the information, and 3) the governing actor. i.e., the actor who regulates the interaction between the creator and the receiver.  In our case, that would include the government as creator, the public as receiver (with an implicit requirement for government transparency), and the leakers (and perhaps the press who transmitted the leaked information) as the governing actor.  The pertinent question one may raise, however, is how could better or stronger information governance have informed the actors and prevented Wikileaks from happening in the first place, or mitigated its effects once it occurred?

A fuller analysis of these three actors awaits a different paper in perhaps a different subject matter area.  In our role as information professionals, our work laying the problem out in these terms, i.e., defining the institutional repository space (and even naming it as such), explaining the information policy roles (as there are numerous information policy applications at work), and setting forth the information governance aspects contributes significantly to a deeper understanding of the problems that exist and facilitates their solution in a complete and interdisciplinary way.  Our work done, we pass it on to other professionals, safe in the knowledge that the completion of our tasks, as information professionals, made a vital contribution to the overall discourse.
