  • Summary

    Evaluation should be an integral part of any teaching or training. Evaluation will let you know whether your learners have achieved the intended learning outcomes and it is an opportunity to gather evidence of the impact of your teaching sessions. Evaluation and assessment are closely linked.

    Methods of evaluation should be considered when developing teaching and embedded throughout the teaching process, not just bolted on to the end of a session. Evaluation is often thought of as the printed form handed out at the end of courses, but it should be a much more considered process that is integral to your planning, development and delivery. Take every opportunity to gather evidence of the impact of your teaching.

    Evaluation can take place on different levels. Although designed for the business context, Kirkpatrick's (1959) four levels of evaluation model is widely used. The levels are:

  • 1 Reaction

  • This is how the learner feels at the end of your teaching session or course. It is usually measured by the ‘happy sheet’, so named as it can really only measure at the reaction level. This is an opportunity to gather learners’ opinions on your session, including practicalities such as organization, venue, refreshments, etc., but also on content – did they feel the session was useful? Did the session meet its aims? This can also be a good opportunity to find out what further training is needed. You can attempt to measure beyond reaction by asking how learners will use the knowledge and/or skills gained in the session.

  • 2 Learning

  • This relates to knowledge or skills acquisition – what did the learners actually learn? This is where evaluation is closely linked to assessment. This does not necessarily mean formal assessment via an exam, etc., but could be informal questioning by the teacher or a demonstration of skills in a practical session. In your planning, think about how learners can demonstrate that they have learned what you are trying to teach – this should impact the design of your session.

  • Summary

    What this book covers

    The title of this book makes a very big claim. No one can possibly know the answers to all the questions that a student, researcher or academic might ask, nor should they claim to do so. Information resources are constantly evolving and one of the key tasks of the librarian is to make sure that he or she keeps up to date.

    What this book does offer is a survival guide for front-line staff to help them find appropriate information quickly, whether they are answering questions at a physical help desk or remotely by telephone, e-mail or instant messaging service.

    The entries cover a range of queries commonly encountered in the academic library. They are also of relevance to public library staff assisting visiting students. The key categories covered are:

  • • Study skills. Citing and referencing; literature-searching techniques; social research methods and avoiding plagiarism.

  • • Locating different types of resources. Starting-points for finding commonly requested types of material, including: archives; dictionaries; book reviews; biographical information; conference papers; encyclopedias; images; films; statistical data; maps; market research reports; opinion polls; newspapers; government publications; quotations and speeches.

  • • PhD and researcher questions. Basic guidance to common queries such as how to trace theses and dissertations; locating sources of funding; and searching for books and journals in other libraries.

  • • Academic staff questions. Starting-points for tackling questions relating to open access publishing; copyright licences; finding bibliometric data; and tracing online teaching and learning resources.

  • • Subject literature searching. Some basic starting-points for beginning research in a number of commonly encountered academic subject areas. The full list of these is: Accountancy; Art; Business Studies; Computer Science; Criminology; Development Studies; Economics; Economic History; Education; Engineering; Environment; European Union; Geography; History; Human Rights; International Relations; Languages; Law; Literature; Management; Marketing; Mathematics; Media Studies; Medicine and Nursing; Music; Philosophy; Religious Studies; Science; Social Welfare and Social Work; Sociology; Sports Studies; Tourism; Women's Studies.

  • • Area studies resources. In addition, key resources for those studying a number of specific regions: African Studies, Asian Studies, Latin American Studies, Slavonic and East European Studies are also provided.

  • Summary

    This activity is ideal for any topic that involves debate such as issues relating to copyright, plagiarism, authority, privacy online or managing your online reputation. Arrange chairs in a circle, placing two in the centre. Two volunteers should sit in the central chairs and begin the debate: they are in the centre of the ‘goldfish bowl’, being observed by the wider group. If a member of the wider group wants to join the debate, challenge one of the speakers or have their own say, they must tap one of the learners in the middle on the shoulder, and then wait their turn.

    ✓ BEST FOR

  • • confident learners

  • • providing a novel approach to managing discussion in a large group

  • • enabling participants to see how to structure a debate

  • • energizing discussion by involving movement

  • • providing an effective compromise between involving the whole group in a learning activity, and having something managed and focused.

    • + MORE

  • • As preparation for the goldfish bowl, divide the class into small discussion groups and give each group one side of the debate to research and discuss. This will mean learners have a chance to consider the issues relating to the debate and encourage learners to be more confident in their contributions. The preparation could take place immediately prior to the goldfish bowl, or set as homework.

  • • Break up a large group into two or more simultaneous goldfish bowls – this might be less daunting to participants and thus encourage participation.

  • • Some example topics for discussion:

  • — Is it OK to download music illegally?

  • — What is wrong with copying and pasting for my class work?

  • — Privacy online: Google and Facebook retain a lot of your personal information – is this good or bad?

    • : WATCH OUT

  • • This activity requires a motivated group of learners in order to work well. The choice of topic is vital as it must be one that engages the group and thus provoke discussion.

  • • Keep an eye out for the discussion being dominated by a few members of the group. You may have to encourage quieter learners to contribute.

  • • If the discussion stalls, be prepared to join in yourself with some controversial or thought-provoking comments or questions.

  • Summary

    The main goal of an information service is to meet the user requirements for finding and accessing relevant information. In other words, users are, or at least should be, at the centre of any information service irrespective of whether it is free or fee‑based, local or remote. Prompted by the introduction of computers in information processing in the late 1950s, a large variety of online databases and information search services began to be marketed in the 1960s. The rate of growth of local and remote online information services has increased significantly with the appearance and proliferation of the internet and the world wide web some two decades ago. Information services now play a major part in almost all our day‑to‑day activities in today's society.

    However, information services existed long before the invention of computers. Traditionally, libraries provided information services, and libraries have existed for centuries. Users, and ease of use of information, were the two major driving forces behind these services. The importance of users in the context of library and information services was acknowledged by Ranganathan (1963) in his famous Five Laws of Librarianship in the 1930s:

  • • Books are for use.

  • • Every reader his book.

  • • Every book its reader.

  • • Save the time of the reader.

  • • A library is a growing organism.

    • It may be noted that although Ranganathan conceived these laws nearly a century ago in the context of libraries, they are very much applicable in today's electronic information world where one can easily reword these laws to state:

  • • Information is for use.

  • • Every user her [piece of] information.

  • • Every [piece of] information its user.

  • • Save the time of the user.

  • • Information is a growing organism.

    • In other words, while creating and/or managing an information service, we should always keep users in mind so that every bit of information stored within the system is accessible by its target users, and as a corollary users of the information system or service should find the information they require efficiently and effectively.

  • Summary

    Introduction

    Wilson (2000) commented, ‘However we define it, and from whatever year we choose to date it, information science has been concerned with the information user.’ As discussed in Chapter 1, user studies, as we understand them today, first appeared as an area of research in the context of information studies in 1948. Over the past six decades user studies has remained a major area of research, giving rise to several theories, models and new principles published in thousands of research papers and reports. Later Wilson (2008, 174) observed that ‘apart from information retrieval theories virtually no other area of information science … has occasioned as much research effort and writing as “user studies”’.

    In October 2010 a quick search on the ISI Web of Knowledge database for ‘user studies’ produced 11,798 hits: 6534 hits in computer science, 2848 in engineering, 2279 in psychology, 2268 in education and educational research, 1702 in behavioural sciences, 1298 in telecommunications, 1265 in information and library science, and 1042 in health sciences, demonstrating that user studies is a major area of research in different disciplines. Wilson (2008) observed that ‘information needs’ has remained a major area of investigation within user studies but, commenting on this claim, Bawden (2008) pointed out that progress towards having a theoretical understanding of information needs has been slow.

    User studies and information needs are increasingly challenging areas of research in the modern digital age, where numerous information products are services are being created for consumption by remote and widely varied categories of users. Some typical examples of information in a variety of information products and services were discussed in Chapter 1; for example the two BBC websites shown in Figures 1.4 and 1.5 show examples of different kinds of information services designed for different categories of customers of the BBC. Illustrations of other websites in Chapter 1 demonstrated that every organization or institution takes a different approach in designing and offering their online information products and services in order to meet the needs of their target audience or customers. Other examples of information products and services range from numerous search engines and digital libraries to handheld communication and entertainment devices such as mobile phones, iPods and iPads, and e‑books readers like the Sony e‑book readers and Amazon Kindle.

  • Summary

    Introduction

    As discussed in Chapter 4, the success of a usability study depends significantly on the selection of appropriate study participants. Sometimes it is not easy to identify who the actual and potential users of an information product or service are, and this makes the job of selecting participants for a usability study even more difficult. However, combining the most suitable groups of study participants and the most appropriate data collection methods can produce the best results in a usability study. This chapter discusses some basic issues related to the selection of participants for usability studies of information products and services. It also discusses various techniques for user sampling and the ethical requirements associated with the selection of study participants and usability studies in general.

    Selection of study participants

    An information product or service is designed to meet the information requirements of a group of users. Depending on the nature and content of the specific information product or service, sometimes these users can be very specific, for example, a group of scientists, professionals or researchers, or members of the general public. Nonetheless, the overall goal of a usability study is to assess how far the given information product or service achieves its stated objectives of meeting the information needs of the target users. Hence knowing who the target users are of an information product or service is the first step in conducting a usability study.

    Creating a user profile

    Before designing an information product or service, it is important to identify the potential users, record their information behaviour, and find out the tasks or activities for which they would need to use the information product or service. This information is used to create a user profile, which forms the basis of the design. This information can also be used at a later stage of the product lifecycle in order to conduct usability testing.

    Usually a user profile is created at the very early stages of a product development. This is dictated by the business and goals of the organization that is developing an information product or service, the nature of the product, the specific objective and goals of the product, the target users, and the specific tasks or activities for which they would need the new or modified information product or service.

  • Summary

    Introduction

    Usability studies, in the words of Rohrer (2008), are ‘blessed (or cursed) with a very wide range of research methods, ranging from tried‑and‑true methods such as lab‑based usability studies to those that have been more recently developed, such as desirability studies (to measure aesthetic appeal)’. Indeed, as discussed in Chapter 4, a usability researcher can adopt a variety of approaches and methods for conducting usability research. Irrespective of the study approach – quantitative or qualitative – usability research often generates a large volume and variety of data that needs to be analysed and interpreted appropriately in order to produce useful results and draw appropriate conclusions. If a quantitative approach is adopted, one or more appropriate statistical methods have to be used in order to analyse the data.

    Quantitative data can be presented in a variety of ways using tables, charts and so on. Such simple data analysis and presentation techniques provide descriptive statistics as the study findings, but in most statistical studies it is expected that results can be generalized for the entire study population and inferences can be drawn. In doing so, it is also important that the findings are taken with some degrees of confidence, the most common one being a 95% confidence level – the findings can be true for 95% of cases. Depending on its nature and design a usability study may involve a number of data variables that may be independent or dependent on one another, and the data variable may have different characteristics that need to be analysed and interpreted according to appropriate statistical techniques. Consequently, one or more statistical methods need to be used in order to analyse and interpret statistical data properly.

    In summary, a usability researcher needs to know at least some of the basic statistical techniques and measures in order to complete a usability study successfully and generate results that can be taken with confidence and generalized appropriately. Again, in addition to employing quantitative analysis techniques, in order to generate statistical data, a usability researcher may also employ some qualitative analysis techniques in order to conduct some in‑depth analysis and gather data on specific features and functionalities – for example user preferences and the reasons behind them – of an information product or service.

  • Summary

    Introduction

    Over 10,000 articles have been published on different aspects of human information behaviour (HIB) research and there has been a steady growth since 2000: ‘30 items per year during the early 1970s, 40 during the early 1980s, 50 by the late 1980s, 100 by 1990, and 120 items per year by 2005’ (Case, 2007, 242). Keeping track of such a rapidly growing literature is a challenging task. Fortunately, a representative range of literature has been reviewed in several publications including:

  • • ‘60 Years of the Best in Information Research on User Studies and Information Needs’ by Wilson (2006b)

  • • ‘Users, User Studies and Human Information Behaviour: a three decade perspective on Tom Wilson's “On user studies and information needs”’ by Bawden (2006)

  • • A chapter in Annual Review of Information Science and Technology, ‘Information Behavior’ by Case (2006)

    • In addition, a number of sources have emerged which deal exclusively or predominantly with information seeking, for example:

  • • Information Seeking in Context (ISIC) conference series since 1996

  • • special issues of several journals including Informing Science (3 (2), 2000), Journal of the American Society for Information Science and Technology (55 (8), 2004), Journal of Documentation (62 (6), 2006, and 63 (1), 2007), Information Processing & Management (‘Designing for Uncertainty’, 2008) and Library & Information Science Research (23 (4), 2001)

  • • the electronic journal Information Research (http://informationr.net/ir/), edited and published by T. D. Wilson

  • • a number of recent books including: Looking for Information (Case, 2007), New Directions in Human Information Behaviour (Spink and Cole, 2005), The Turn (Ingwersen and Jarvelin, 2005) and Theories of Information Behaviour (Fisher, Erdelez and McKechnie, 2006).

    • The chapter begins with the definition of HIB, and information seeking and retrieval. It sets the overall background of HIB study in general, then discusses the concept of information seeking and retrieval, which is a subset of HIB research, and an important aspect of usability of information products and services. Several models in the literature aim to provide a theoretical underpinning of HIB and the information seeking and retrieval process, focusing particularly on human aspects. Therefore, some widely used information seeking behaviour models and some new models derived from recent research work are discussed in this chapter. The new information seeking models will offer some insights of new directions of information behaviour research.

  • Summary

    Introduction

    Although general evaluation and performance measurements of library and information services, and evaluation of information online information services and databases have a long history, usability studies of information websites and online information products and services are of recent origin. Methods, tools and technologies that have been developed and used within software communities – the human–computer interaction community in particular – and subsequently in the context of the web have been adopted for usability research in the context of online information products and services. However, since users are at the core of any usability study and user studies have remained a major area of research within the information science community, many methods and techniques that were developed for user studies have been adopted and used in usability research. While significant amounts of progress have been made to usability research in information, many new challenges have also appeared over the past few years. Some of these challenges result from the changing nature of the web and emerging technologies, standards and so on; others are caused by the very nature of the web and ICTs that are affected by many factors, including the digital divide, digital and information literacy and the fast changing nature of society caused by the culture of web and mobile technologies, social networking technologies and so on. These emerging technologies and culture bring tremendous opportunities as well as challenges for usability researchers within the information science community. This chapter provides a quick overview of some of the emerging technologies and challenges and points out some new research to show the trends and opportunities in usability research.

    Usability methods and techniques

    As discussed earlier in this book, usability studies in digital libraries and online information products and services use a variety of methods and techniques, most of which were originally developed within the software engineering and human–computer interaction research communities. However, some tools and techniques, such as transaction log analysis, eye tracking and cognitive studies of users, are of relatively recent origin and have been adopted from other fields of studies. Similarly, other areas of study and corresponding methods and techniques, such as in the digital divide, information literacy and so on, are being brought within usability research since they have a significant impact on the usability of online information products and services.

  • Summary

    Introduction

    Usability studies of digital libraries primarily aim to find out how easily users can interact with the interface of the digital library, find useful information and use retrieved information to accomplish specific tasks, and what their general impressions about the various features and functionalities of the library are. Some usability studies also aim to gather information about the non‑users with a view to finding out why potential users don't use the digital library, and what can be done to make it usable for them.

    Chowdhury, Landoni and Gibb (2006) suggested that usability of a digital library depends on a number of factors, such as the effectiveness and efficiency of the information access system, the ease of use and friendliness of the user interface, users’ needs, usage patterns and so on. Sumner (2005) emphasized that understanding the needs and type of work of users, and innovative user interfaces and interaction mechanisms can influence better use of digital library resources, collections and services. Park (2000) observed that the heterogeneity and distribution of information resources is also an important usability factor. Bishop et al. (2000) pointed out that a digital library is a space where users engage with the information infrastructure, so user problems, user attitudes, specific use situations and work practices are important points for usability studies.

    There have been a number of usability and evaluation studies of digital libraries over the past two decades, which have used a variety of usability study techniques and methods of data collections and analysis. Several models for usability and evaluation of digital libraries have also been proposed by research ‑ ers. This chapter discusses various issues related to the usability of digital libraries and discusses the factors that researchers have identified as important for usability studies of digital libraries. Finally it discusses some usability study models, with particular reference to MEDLIS, a usability study model developed by one of the authors of this book in the course of a research project.

  • Summary

    Introduction

    As discussed in Chapter 1, usability is a quality attribute of information services and products. Usability research aims to gather data on how a particular information service or product is used and perceived by users, how far the given product or service meets its stated objectives, where users find difficulties in using the product or service, if any, and so on. Usability studies may be conducted at different stages of the lifecycle of an information product or service. At the design stage data relating to the anticipated or expected uses of a specific information service or product can be gathered through a usability study. More usability information relating to how far an information product or service meets its stated goals can be gathered after development of the prototype but before implementation. Again usability information has to be gathered at different intervals when the product is on the market in order to gather data on the usage patterns and user perceptions about the strengths and weaknesses of the given information product or service. In summary, usability studies need to be conducted throughout the lifecycle and different information is gathered to help improve the product or service and to remain effective and competitive in the marketplace. This chapter discusses the concept of usability in more detail and how to conduct a usability study at different stages of a product lifecycle, including various approaches, tools and techniques.

    Usability

    The definition of usability provided in ISO 9241-11:1998, mentioned in Chapter 1, emphasizes that usability is a measure of the extent to which a given product can be used by specified users to achieve some specified goals. It also reminds us that users should be able to use the given product with effectiveness, efficiency and satisfaction in a specified context of use. This definition therefore suggests that to measure usability, we need to:

  • • identify a subset of the specified set of users and involve them in the study, and then

  • • study the selected participants’ context and goals for which they are going to use the product

  • Summary

    It has become a common part of our everyday life to use a variety of online information products and services. These include e‑mail and web services, search engines, mobile applications, library catalogues, scholarly databases and digital libraries. Online information services have existed for around 50 years. They appeared in the early 1960s providing facilities for remote access to online library catalogues and bibliographic databases of scholarly information comprising abstracts or full texts of journal and conference papers. Since then a significant amount of research and development activity has taken place to improve online information services. While some of these research activities focused on developing better information search and access mechanisms, others have focused on measuring the effectiveness and efficiency of online information databases and search services.

    Early research on the evaluation of information retrieval systems focused on developing parameters for measuring the level of performance of various retrieval systems and techniques. Originally these evaluation experiments were based on small test collections, which were used to measure the performance of specific online databases or search systems. Subsequently the size of the test collections grew and the retrieval evaluation research became more robust, focusing on more complex retrieval algorithms and research problems. At the same time, research on human information behaviour focused on different research problems related to information needs and user behaviour, and the number of online information systems grew rapidly, giving rise to a large number of models on general human information behaviour, information seeking and retrieval. Thus progress in information systems and services has significantly benefited from systems‑ and usercentred evaluation research in information. Together this research aimed not only to assess the performance measures of various information retrieval systems based on certain specific retrieval measures, but also to understand information seeking and retrieval behaviour and patterns to address such questions as why certain systems perform better than the others, why users like or don't like certain system features, and so on.

    Introduction

    The distinction between those who have access to information and communication technologies (ICTs) and those who do not is called the digital divide. It marks the disparity between ICT ‘haves’ and ‘have nots’. At first the digital divide was defined in binary terms: a gap between ICT ‘haves’ and ‘have nots’, but more recently researchers (Norris, 2001; Chowdhury, 2004) have noted that a digital divide can be of different types:

  • • the social divide: the difference in access between diverse social groups

  • • the global divide: the difference in access to the internet

  • • the democratic divide: the different applications and uses of online information to engage and participate in social life.

    • There is a general belief that the digital divide only exists between the developed and developing counties. While this is true – because of the lack of ICT infrastructure, telephone and internet access, and generally poor educational level and socio‑economic conditions of the population in developing countries – a digital divide also exists among different sectors of societies in developed countries.

    How does the digital divide affect usability of information products and services? Obviously if people have no or only limited access to ICTs in general, and internet and digital information services in particular, they will use no online information products and services, or fewer than others do. This chapter discusses the concept of the digital divide, how it is measured, and associated parameters such as digital literacy. It provides some statistics to indicate how the digital divide exists in different nations in the developed and developing world, and discusses how the digital divide affects the usability of information products and services and what lessons can be learned relating to digital literacy research.

    Connotations of the digital divide

    In a report on the digital divide the Organisation for Economic Co‑operation and Development (OECD) (2001) defines the digital divide as ‘the gap between individuals, households, businesses and geographic areas at different socio‑economic levels with regard to their opportunities to access information and communication technologies (ICTs) and to their use of the internet for a wide variety of activities.

    Introduction

    The web has brought a major revolution in the way we create, disseminate, access and use information. It has opened new opportunities for creators and users of information products and services because through the web any information product or service can virtually reach every user on the planet. There are challenges, too, because since users are remote, and sometimes unknown, it is often difficult to design an information product or service that would meet the requirements of every potential user. Yet every information product or service developer dreams to use the web to make their products or services available to users, however large or small the user groups are and whether they live next door or thousands of miles apart. All organizations – whether a government organization, an international organization like the United Nations, a city council, a university, a business, a professional organization or a charity – now use the web to make their information products and services available to potential consumers. Some of these information products and services are free, others require consumers to register and pay.

    In order to remain competitive on the market, or to constantly improve the quality of their information products or services, organizations need to conduct usability studies. Although it is possible through the web to reach a large number of consumers with an information product or service, a poorly designed website, product or service can easily frustrate and alienate consumers thereby causing a loss of business for the organization. Usability specialists are often employed at every stage of the design of an information product or service, and regular usability studies are conducted once a product or service is on the market in order to detect problems, improve quality and stay competitive. Conducting such usability studies is often challenging, but fortunately a number of guidelines and tools are available for the purpose. This chapter discusses some of the tools and techniques that can be used to conduct usability studies of web‑based information services.
