Abstract

Mobile technologies are becoming very accessible to students, due to advances in the development of technology and a simultaneous decline in hardware costs. In this way, it is relevant to consider the potential of these devices in teaching and learning. Our research was designed to evaluate the possibility of creating gamebooks (gamified books) that are effective in teaching and learning. After analyzing the features available in many free or open tools for making ebooks we find out that these tools were not appropriate creating gamebooks. This paper presents a novel interactive book, the gamebook (g-book): a book with a story that can be read sequentially or not. The main difference refers to the ability to choose different paths to the main characters or the unfolding of the history, as happens in games. We built a model of a dynamic book that functions as an educational game for "Environmental Studies", aimed at children in the 4th grade, mostly 9-10 years old, in Portuguese schools. This paper presents the design and features of this g-book titled "Adventures in the Guadiana River", implemented with the Unity3D platform that can be explored in iPhones, iPads, Android mobile devices and web browsers for the OSX and Windows platforms. Preliminary tests with our prototypes revealed very good usability and promising pedagogical potential in the proposed models.

1. Introduction

Technological advances enable the use of innovative learning tools in education. In the near future, eventually everyone has a smartphone or a tablet that can be used in the classroom for educational purposes. In this context it is wise to consider the integration of digital media and mobile devices (iPad, iPod, tablets, smartphones), allowing students to set personal goals, to manage educational content and to communicate with others in the right context [1].

It is also important to note that this is a generation of digital natives; these students are the generation of digital games and social networks. We cannot ignore that they are no longer the same for which the education system was designed a few decades ago. These students grew in a new technological environment, with its own techno culture, and they will live in a more demanding, competitive and complex world. See, for example, the prospect of Heide and Stilborne [2], for whom "the technological revolution has produced a generation of students who grew up with multidimensional and interactive media sources. A generation whose expectations and world views are different from those that preceded it" (p. 27). Moreover, this is a generation that lives in a very complex world and will have to make very difficult decisions (economy, environment, social welfare, etc.). Unfortunately, school education does not establish the bridges that allow the development of skills for understanding this complexity [3].

With the emergence of (cloud) distributed learning technologies, students can learn in a more informal setting using mobile devices, without being confined to a room full of computers. Furthermore, teachers and educators have emphasized the importance and need for "authentic learning activities", where students can work with real world problems [4]. Therefore, the development of educational activities for students, that combine learning resources from the real world with those from the digital world, has become an important and challenging research topic. This may be accomplished, for example, through the use of mobile communication and wireless technologies, which can be moved to any place, allowing for scientific experimentation, augmented reality, image collection, resource sharing, and communication with colleagues.

In the current context of mobility we wanted to explore the possibility of integrating the typical structure of a game in a new type of electronic book the gamebook (g-book) to be used in tablets. The concept is, in essence, an interactive ebook, which enables the integration of text with images, audio, video and animations. We understand that there are clear pedagogical benefits in the development of an innovation that combines a book with a game with potential in various learning contexts (formal, informal or non-formal). It is this new possibility that we pursue in our investigation, evaluating the potential of the technology in terms of tools and interfaces.

The mobile learning concept is part of a societal model that assumes digital skills as a valid stance. We refer, in particular, the ability to (1) analyze and produce digital information where and when the user wants, (2) make decisions in the context of an information society, (3) apply creative skills and innovation (technological and methodological), (4) engage in collaborative work and (5) master an operational knowledge about digital media and global communications.

This article reports the creation of a gamebook that may be effective in various learning situations. Ongoing research involves the evaluation of three major components, clearly distinguishable: (1) assess the potential of the current ebook technology, (2) study the role of narratives in games, and (3) determine the potential of gamebooks for certain educational applications.

2. Designing Mobile Learning

While reviewing the literature we found several definitions of mobile learning. It should be noted, for instance, the view of Sharples [5], that defines mobile learning as the learning process that is not limited to a fixed place and takes advantage of mobile computing technology. Considering the popularity of mobile devices (e.g, smartphones, tablets and laptops), we realize that most researchers in this field have adopted this definition, which we think remains valid in the second decade of this century.

Traxel [6] defines also mobile learning as learning that is supported by a portable or mobile device. This mobile device encourages learning through its ease of access to information, the ability to easily move and its ability to manage very diverse contents (text, image, audio, video, animation, etc.). The integration of portable devices in the

instructional model is assumed, in the opinion of this author, as a possible way to increase the efficiency of learning. Portable devices have been used since long in curriculum areas such as languages [7], [8], [9], [10], mathematics [11], social studies [12], [13], [14], and science [15], [16].

On the other hand, compared with traditional education based on textbooks, learning with ebooks, coupled with mobile devices, seems to be an increasingly attractive option; one which can trigger the interest and motivation of students. Considering that interactive ebooks may eventually have teaching potential, they can also be distracting and produce some dispersion [17], [18]. On the positive side, Glasgow [19] showed that student's motivation is higher when children interact with multimedia materials, especially those children with reading difficulties. Supporting this view, Bearne [20] argues that most children today are immersed in vast multimedia experiences and are used to combine diverse resources to interact with. In a recent study, Larson [21] suggests that using digital reading devices promotes new literacy practices and extends the connections between text and other relevant learning resources. But despite these encouraging results, the development of multimedia tools and methodologies to improve outcomes in student learning remains an important and challenging question for authors and institutions [22].

Mobile devices may actually promote a new way of "being in school", anytime and anywhere, since in a flipped classroom the student doesn't have to be sitting in front of a computer located in a room or lab [23]. As we shall see, mobile devices have unique features that interest us, namely, in terms of interaction and exploration modes in instructional processes. However, the iPad and other tablets are still recent in the marketplace, so research of its use in education is scarce and shallow [24], [25], [26], [27].

During a study that we conducted in 2009, at the University of Wisconsin in Madison, we verified the existence of well-defined patterns in the use of mobile devices by students [28], explicitly that:

• mobile learning evolves around the social environment of the student (sharing podcasts, images, texts and notes), and is not linked to the classroom;

• learning activities are mainly based on online resources and on interaction with other people (often through academic work);

• collaboration networks and group work are an important aspect of mobile interaction anytime, anywhere;

• the ease of instantly publishing content online stimulates students to become researchers and authors;

the possibility to easily capture, record and publish multimedia transforms students into producers and critics (for example, when interacting in Facebook, Twitter, Flicker or YouTube).

3. Introducing Games in Mobile Learning

Research in educational technology needs to go far beyond learning with multimedia to recognize the role of new learning experiences, for example, one that games and simulations can reveal. The learning model which we call "ludic" - based on games - can be used in formal or informal education by well-defined age groups, and can be introduced in various scientific fields. But how do we broadly define "game"? For our educational purposes a working definition may be the one proposed by Klopfer [29], for whom a game is a goal-oriented activity, based on specific rules, that players perceive as enjoyable. In the educational context, considering that "ludic" is not usually a priority in most activities, a game may be the motivating factor that is needed in many learning resources.

Unfortunately, the production and deployment of educational games is not without difficulties, particularly:

• The high development costs and an uncertain market make investment in educational games and innovations too risky for producers;

• Institutions resist adopting innovations and do not want to make unnecessary changes and investments, including the use of new technologies for learning;

• Instructors, institutions and publishers do not (traditionally) want to replace textbooks with educational games;

• The value of specific educational technologies (games, simulations, etc..) have not been proven in many cases;

• Parents and teachers still have very negative attitudes about the use of games in the classroom;

• Games are especially suited to teach higher order skills that are not typically assessed through examinations (multitasking, decision-making, strategic vision, etc.);

• Easy access to computers and the Internet cannot be taken for granted in educational institutions (the case of many developing countries).

In this context, to overcome many of the difficulties, we wanted to explore the possibility of integrating the structure of a simple game in the last generation of ebooks. The idea is to create an electronic book that enables dynamic integration of text with images, audio, video and animations, but that may be used as a game. We are considering the possibility that the educational system can more easily adopt an innovation like a gamebook - an interactive and ludic book - than conventional electronic games. Is this new possibility that we are interested in studying, based on the emergence of powerful mobile platforms (iPad, tablets, smartphones, etc.), but also relying on previous studies about games-based learning. In brief, we wanted to align ebooks with two learning scenarios: mobile learning and game-based learning.

Furthermore, it makes sense to consider the integration of mobile and game learning in systems managed by students, allowing them to set personal goals, manage content and communicate with each other. In practice, these Personal Learning Environments (PLEs) are made up of several components, which may include social networks, virtual worlds and authoring software, interconnecting various learning resources suitable to the pedagogical contexts and skills to be acquired by each learner. We argue that ebooks (or gamebooks), due to their characteristics and potential for interactivity, can be a valued part of these PLEs.

4. Ebook Formats

At the most basic level, the ebook is an electronic book that can have a simple format, such as a text in PDF. However, there are currently more advanced standards, such as EPUB3 (universal) or iBooks 2 (Apple), that can integrate multimedia components. Ideally, an ebook should have sufficient quality for current devices with their high-resolution displays, and be compatible with a wide variety of reader apps, and if necessary allowing the conversion to other formats. In actuality, however, there are more than a dozen formats not compatible with each other, and sometimes they do not adapt to higher resolution screens.

Over the years, teachers have often used multimedia encyclopedias and textbooks, on CD, DVD, or available online. But more recently emerged a new generation of electronic books that can offer more interactive and dynamic learning experiences. Students of the "Playstation generation" tend to respond better to this dynamic and interactive content, with the ability to display not only text but also other media with hypertext links, search facilities, and connection to online databases. One benefit of these ebooks for students is for example the possibility of being able to select any word that they do not understand and find immediately its definition.

Another potential use refers to the capability to have simultaneously several students accessing the same book and thus share learning experiences. More specifically, they can communicate and share files, having opportunities to communicate in the context of group work, even if accessing from different locations. The ebook can also contain tests, allowing students to make their self-assessment.

An economic advantage refers to financial aspects; currently the cost of textbooks represents a high expense for students and their families. The introduction of electronic books contributes to reducing these costs effectively. Furthermore, it is also expected the emergence of cheaper mobile devices, which is happening in countries such as China and India. Altogether, the widespread use of ebooks will also benefit the environment by reducing paper consumption, bearing in mind that a device may store thousands of ebooks.

On a less positive note, despite huge advances with the technology, many applications used to read ebooks do not have really useful features such as the ability to highlight, mark text, bookmark or write notes. These are apparently trivial matters, but they are important for a student. In a paper book the student usually highlights the most important parts and adds annotations in the margins. In this way, when he reads the book again, he will focus mainly in these parts.

Although there are several standards for ebooks, not all reading applications and mobile devices use the same. Thus, to reach a wide audience, it is necessary to adopt some of the most commonly used formats for reading electronic books, for example, Adobe PDF in computers, Mobi for the Amazon Kindle, EPUB for the Barnes & Noble Nook, and iBook for Apple's iPad. The Portable Document Format (PDF) is the most popular format for creating digital books and can be read by the free Adobe Reader installed on most computers. It is an open standard that enables the creation of ebooks with support to the use of sound, images, video, notes and bookmarks. Its main

advantage is to keep the layout of the printed book within original quality on any device. However, this benefit is a major disadvantage on mobile devices. The text is difficult to handle in a PDF file, when we visualize a page on a mobile device such as a smartphone, the characters become too small forcing the user to increase or decrease size in order to view the contents of the page. In other ebook formats, such as EPUB and iBook, there are no physical constraints to a fixed style and everything scales.

EPUB is a format based on open specifications, primarily written in XML and XHTML. The EPUB format is supported by a wide range of devices and platforms, including Android devices, Nook, iPhone, iPad, iPod, MobiPocket, Adobe Digital Editions, FBReader, Stanza, Sony Reader, and many other readers and applications. Of the most popular devices, the only one that does not support EPUB is the first Amazon Kindle. The EPUB specification is an open standard, allowing the creation of ebooks with sound, images and video (in its newest specification - EPUB3). This specification introduces innovative features to address structure limitations, such as: precise layouts specialized for comic books, support for MathML, support for multimedia, and introduction of notes.

The Amazon Kindle is an electronic book reader very popular in the US. Early versions used the Kindle proprietary format AZW. This is basically the Mobipocket format based on the Open eBook standard using XHTML. This specification supports images, notes and bookmarks. In late 2011, Amazon started selling the Kindle Fire along with the new file format Kindle Format 8 (KF8), which supports a subset of the features of HTML5 and CSS3. This is also a proprietary specification and expands the functionality of the earlier versions of the Kindle, in order for the Kindle Fire to support sound and video.

5. Ebook Authoring Tools

There are several ecosystems and tools that can be used to create ebooks and distribute them for personal computers and mobile devices.

In the previous section, we presented the different ebooks formats that can be considered.

The simplest way to create digital books, for multiple mobile platforms, is to start with PDF or RTF files and use applications, like Calibre, that converts PDF files in multiple formats such as EPUB, or MOBI for the Kindle, among others. Calibre is a free application that runs on Windows, Mac OS X and Linux,

There are other free or open applications that support the creation of electronic books. For example, the application eCub allows the creation of simple books in EPUB or MobiPocket, from text files or XHTML. However, eCub is very limited, with no WYSIWYG capabilities. It is suitable for the production of simple ebooks with front and back pages with an image, index, a title page and it can convert content to a sound file (WAV or MP3). The eCub is free and is available for Windows, Mac OS X, Linux, FreeBSD and Solaris.

Booktype is an open platform, available since 2012, which allows editing and writing of ebooks for different platforms by exporting in PDF, EPUB, MOBI, ODT and HTML. This application also exports the ebook directly to Amazon, Barnes & Noble and iBookstore online stores, as well as to online printing sites. Digital books written with this application are immediately available in any of these platforms. When writing the ebook, the author does not need to worry about formatting, since it will automatically be formatted to work in these different platforms. Booktype also provides a set of collaborative tools for reviewers, editors, translators, designers, and authors, enabling the different participants to work collaborative in the production of an ebook. Some of the features offered by this platform include: intuitive drag-and-drop tools, chat, messages, adding images and text formatting. Booktype also maintains a history of all changes, which allows the author to compare different editions and return to a previous edition. It is even possible to use snippets (pieces of computer code). One of the disadvantages of this platform is the need for installing on a server and accessing via web browser, which requires some additional expertise.

The Firedocs eLML editor [30] can also be used to create ebooks. The eLML framework (eLesson Markup Language) is an XML platform for creating online classes using XML. It exports produced materials in SCORM, HTML, PDF and EPUB format. The main objective is to ensure that classes are modeled according to the ECLASS reference, which defines five distinct sections: Entry, Clarify, Look, Act, Self-assess, Summary. Current implementation only supports JPG, PNG, GIF and SVG images. It does not allow Java scripts and forms, so some of

the functionalities as the glossary, references to labels and self-assessment tests are not available in the EPUB format.

Sigil is an open WYSIWYG editor used by Google to create ebooks following the EPUB2 specification for Windows, OS X and Linux. This application imports, creates and edits XHTML documents and exports them into EPUB2 documents. Ebooks created with Sigil may contain text, pictures and links, but this standard does not support video or sound. It also provides multiple views of the work: book, code and a split mode. In the book view, it allows content edition in WYSIWYG mode.

Finally, we should mention the electronic books created in the iBook format from Apple. These ebooks are created with a free application - the iBooks Author tool. The format is proprietary, although based on the EPUB standard specification, with some differences in the CSS3 tags. This tool makes the process of creating ebooks very easy, by presenting a very complete set of integrated features, including: sound, image, video, dictionary, text underline, annotations, text-to-speech conversion, navigation and many widgets to enhance the interactive experience. The introduction of widgets in the iBook is an enriching experience for readers of an electronic book. iBook Author offers seven types of pre-defined widgets: (1) photo gallery, (2) video or audio media file, (3) review questions, (4) slide show; (5) interactive tagged images, to give detailed information on specific parts of an image or graph, (6) 3D models, and (7) objects created in HTML. The ease of creating widgets allows users to add any object to an interactive iBook, and there are many possibilities, from calculators, puzzles, maps, YouTube videos, among many others. Table 1 summarizes the characteristics of the authoring applications surveyed.

6. A Game-Book Prototype

This section presents the implementation of a novel concept, the gamebook (g-book).

We were looking in the process of creating a prototype of an electronic book and we started out with the idea of a g-book - a book with a story that can be read sequentially or not. The main difference refers to the ability to choose different paths to the main characters or the unfolding of the history, as happens in games. The reader/player makes choices that affect how the story unfolds and his decisions have a significant impact on events and the final outcome.

Some choices may be as simple as turning right or left at the end of a road. Others may be much more difficult, requiring decisions about facts or occurrences, such as, problems arising in natural disasters, environmental pollution and climate change. In a particular story the student may be the main character - the hero of the story - or

simply manipulate variables with consequences at the strategic level. Thus, not only decisions change the story, but also the sequence of choices can change the ending.

A gamebook may follow typical genres and formats of electronic games, such as puzzle, RPG, adventure, strategy, among others, where the reader will face threats, adversaries, and discover the truth behind an intricate story. Ultimately, in this project we strive to create a didactic narrative built on situations capable of providing expectation, suspense, challenge and other positive emotions. Based on the latter, it is theoretically possible to engage students in the study of a particular subject matter, and get more results in terms of attention, retention and understanding. In fact, the possibility and value of integrating game play in learning practices is indicated clearly by several researchers, who recognize its potential in making learning more meaningful and in assimilating new subject matter [31], [32], [33], [34], [35].

The ongoing research involves three strategic components, clearly distinguishable in our workflow:

1. Establish the potential of the technology: the most common formats and authoring tools that allow the creation of gamebooks that are effective in learning;

2. Identify the role of narratives and games: what kinds of narrative and game genres can be recreated as gamebooks for learning, and what learning activities can be prepared based on this typology.

3. Demonstrate real educational applications: according to a specific level of education, what pedagogical models can better integrate gamebooks, and in which subject areas are most effective.

We started by exploring the Apple iBook format [36], essentially due to the vast potential for multimedia authoring with the iBooks Author tool. We built a model of a dynamic book considering all the multimedia features and widgets available. However, this was still an e-book, since using the features available we could not implement the desired g-book. Another question arised is that in this case the e-book is available only for the iOS mobile devices.

We also experimented the EPUB3 standard with the creation of a dynamic book about a beautiful lagoon with a diversified fauna and flora in the middle of Portugal (Obidos) [37]. In the project we tried many different widgets and scripts that somehow emulated the effects achieved with the Apple format iBooks. Still, this implementation was not implemented like a g-book as we desired.

Since we were not able to implement the desired g-book with the traditional ebook authoring tools we decided to explore the Unity3D platform.

Unity3D is a game development tool. It is an integrated authoring tool for creating video games or other interactive content such as architectural visualizations or real-time 3D animations. Unity's development environment runs on Microsoft Windows and Mac OS X, and the applications it produces can be run on Windows, Mac, Xbox 360, PlayStation 3, Wii, ipad, iphone, as well as Android mobile devices. It can also run the developed prototype in a web browser using the Unity web player plugin, supported on Mac and Windows.

In this way, we developed a novel educational g-book prototype for the curriculum of "Environmental Studies", fit for the children in the 4th grade program, with the title "Adventures in the Guadiana River" (fig. 1).

In addition to a story that can be followed by reading the text, consisting of a trip along the Guadiana River, there are several devices that make the development of the narrative more memorable. First of all, a basic text adapted to the target audience was illustrated with appealing images and galleries on various aspects of the river, emphasizing its environmental context. To ensure the engagement of readers, the narrative requires the fulfilment of certain tasks that are supported by interactive activities, in particular, the inclusion of thematic videos and their exploitation through multiple-choice questions (fig. 2).

Our ultimate goal is to allow students the possibility to choose different paths to the unfolding of the story. The prototype already has a narrative based on a journey of discovery, with various unexpected situations to maintain interest. For now, the implemented g-book allows the student to progress to the next chapter of the book if the student answers half of the questions of a quiz correctly (fig. 3).

7. Conclusions

After studying the current state of the art in ebook technology (free and open), we find out that existing tools for ebook authoring were not indicated to design the g-book that we were pursuing.

This paper presented the g-book that we created with the Unity3D platform, with the advantage that it is available for iOS and Android mobile devices and for the web.

The g-book concept has the potential to challenge students to become actively involved in the educational process, as it allows students to try different routes and distinguish what is important from what is secondary, enabling them to create and annotate material from various sources, while also encourages the exploration of new issues. These are, however, aspects that need to be investigated and validated by future research in the educational context.
