Wiki Html Editors Comparison Essay

An HTML editor is a computer program for editing HTML, the markup of a webpage. Although the HTML markup a web page can be written with any text editor, specialized HTML editors can offer convenience and added functionality. For example, many HTML editors handle not only HTML, but also related technologies such as CSS, XML and JavaScript or ECMAScript. In some cases they also manage communication with remote web servers via FTP and WebDAV, and version control systems such as Subversion or Git. Many word processing, graphic design and page layout programs that are not dedicated to web design, such as Microsoft Word or Quark XPress, also have the ability to function as HTML editors.

Types of editors[edit]

There are two main varieties of HTML editors: textual and WYSIWYG (what you see is what you get) editors.

Text editors[edit]

Text editors intended for use with HTML usually provide at least syntax highlighting. Some editors additionally feature templates, toolbars and keyboard shortcuts to quickly insert common HTML elements and structures. Wizards, tooltip prompts and autocompletion may help with common tasks.

Text editors commonly used for HTML typically include either built-in functions or integration with external tools for such tasks as version control, link-checking and validation, code cleanup and formatting, spell-checking, uploading by FTP or WebDAV, and structuring as a project. Some functions, such as link checking or validation may use online tools, requiring a network connection.

Text editors require user understanding of HTML and any other web technologies the designer wishes to use like CSS, JavaScript and server-side scripting languages.

To ease this requirement, some editors allow editing of the markup in more visually organized modes than simple color highlighting, but in modes not considered WYSIWYG. These editors typically include the option of using palette windows or dialog boxes to edit the text-based parameters of selected objects. These palettes allow editing parameters in individual fields, or inserting new tags by filling out an onscreen form, and may include additional widgets to present and select options when editing parameters (such as previewing an image or text styles) or an outline editor to expand and collapse HTML objects and properties.

WYSIWYG HTML editors[edit]

WYSIWYG HTML editors provide an editing interface which resembles how the page will be displayed in a web browser. Because using a WYSIWYG editor may not require any HTML knowledge, they are often easier for an inexperienced computer user to get started with.

The WYSIWYG view is achieved by embedding a layout engine. This may be custom-written or based upon one used in a web browser. The goal is that, at all times during editing, the rendered result should represent what will be seen later in a typical web browser.

WYSIWYM (what you see is what you mean) is an alternative paradigm to WYSIWYG editors. Instead of focusing on the format or presentation of the document, it preserves the intended meaning of each element. For example, page headers, sections, paragraphs, etc. are labeled as such in the editing program, and displayed appropriately in the browser.

Difficulties in achieving WYSIWYG[edit]

A given HTML document will have an inconsistent appearance on various platforms and computers for several reasons:

Different browsers and applications will render the same markup differently.
The same page may display slightly differently in Internet Explorer and Firefox on a high-resolution screen, but it will look very different in the perfectly valid text-only Lynx browser. It needs to be rendered differently again on a PDA, an internet-enabled television and on a mobile phone. Usability in a speech or braille browser, or via a screen-reader working with a conventional browser, will place demands on entirely different aspects of the underlying HTML. All an author can do is suggest an appearance.
Web browsers, like all computer software, have bugs
They may not conform to current standards. It is hopeless to try to design Web pages around all of the common browsers' current bugs: each time a new version of each browser comes out, a significant proportion of the World Wide Web would need re-coding to suit the new bugs and the new fixes. It is generally considered much wiser to design to standards, staying away from 'bleeding edge' features until they settle down, and then wait for the browser developers to catch up to your pages, rather than the other way round.[1] For instance, no one can argue that CSS is still 'cutting edge' as there is now widespread support available in common browsers for all the major features,[2] even if many WYSIWYG and other editors have not yet entirely caught up.[3]
A single visual style can represent multiple semantic meanings
Semantic meaning, derived from the underlying structure of the HTML document, is important for search engines and also for various accessibility tools. On paper we can tell from context and experience whether bold text represents a title, or emphasis, or something else. But it is very difficult to convey this distinction in a WYSIWYG editor. Simply making a piece of text bold in a WYSIWYG editor is not sufficient to tell the reader *why* the text is bold - what the boldness represents semantically.
Modern web sites are rarely constructed in a way that makes WYSIWYG useful
Modern web sites typically use a Content Management System or some other template processor-based means of constructing pages on the fly using content stored in a database. Individual pages are never stored in a filesystem as they may be designed and edited in a WYSIWYG editor, thus some form of abstracted template-based layout is inevitable, invalidating one of the main benefits of using a WYSIWYG editor.

Valid HTML markup[edit]

HTML is a structured markup language. There are certain rules on how HTML must be written if it is to conform to W3C standards for the World Wide Web. Following these rules means that web sites are accessible on all types and makes of computer, to able-bodied and people with disabilities, and also on wireless devices like mobile phones and PDAs, with their limited bandwidths and screen sizes. However, most HTML documents on the web do not meet the requirements of W3C standards. In a study conducted in 2011 on the 350 most popular web sites (selected by the Alexa index), 94 percent of websites fail the web standards markup and style sheet validation tests, or apply character encoding improperly.[4] Even those syntactically correct documents may be inefficient due to an unnecessary use of repetition, or based upon rules that have been deprecated for some years. Current W3C recommendations on the use of CSS with HTML were first formalised by W3C in 1996[5] and have been revised and refined since then. See CSS, XHTML, W3C's current CSS recommendation and W3C's current HTML recommendation.

These guidelines emphasise the separation of content (HTML or XHTML) from style (CSS). This has the benefit of delivering the style information once for a whole site, not repeated in each page, let alone in each HTML element. WYSIWYG editor designers have been struggling ever since with how best to present these concepts to their users without confusing them by exposing the underlying reality. Modern WYSIWYG editors all succeed in this to some extent, but none of them has succeeded entirely.

However a web page was created or edited, WYSIWYG or by hand, in order to be successful among the greatest possible number of readers and viewers, as well as to maintain the 'worldwide' value of the Web itself, first and foremost it should consist of valid markup and code.[6] It should not be considered ready for the World Wide Web, until its HTML and CSS syntax have been successfully validated using either the free W3C validator services (W3C HTML Validator and W3C CSS Validator) or some other trustworthy alternatives.[6]

Accessibility of web pages by those with physical, eyesight or other disabilities is not only a good idea considering the ubiquity and importance of the web in modern society, but is also mandated by law. In the U.S., the Americans with Disabilities Act and in the U.K., the Disability Discrimination Act place requirement on web sites operated by publicly-funded organizations. In many other countries similar laws either already exist or soon will.[6]Making pages accessible is more complex than just making them valid; that is a prerequisite but there are many other factors to be considered.[7] Good web design, whether done using a WYSIWYG tool or not needs to take account of these too.

Whatever software tools are used to design, create and maintain web pages, the quality of the underlying HTML is dependent on the skill of the person who works on the page. Some knowledge of HTML, CSS and other scripting languages as well as a familiarity with the current W3C recommendations in these areas will help any designer produce better web pages, with a WYSIWYG HTML editor and without.[8]

Wikis

Wikis

A wiki is a collaborative tool that allows students to contribute and modify one or more pages of course related materials. Wikis are collaborative in nature and facilitate community-building within a course. Essentially, a wiki is a web page with an open-editing system.  Wikis in Plain English is a short movie describing what a wiki is and how it can be used in a collaborative process.  According to a recent Essay on Teaching Excellence, wikis provide a vehicle for exercising most, if not all, of Bloom’s ‘higher order thinking’ activities.

In many classrooms, the instructor provides most of the course content. With wikis, students have an opportunity to create – together – much of the course content.  Wikis shift your students from ‘consumer of knowledge’ to ‘creators of knowledge,’ which is a great way to encourage your students to develop critical thinking skills, to learn from one another, and to improve their ability to work in groups. There are many benefits of using wikis and you can probably think of other reasons your students would benefit from using this collaboration tool.

When to use a wiki

As you’re beginning to see, wikis are ideal for group projects that emphasize collaboration and editing. Some common uses include:

  • Mini research projects in which the wiki serves as documentation of student work
  • Collaborative annotated bibliographies where students add summaries and critiques about course-related readings
  • Compiling a manual or glossary of useful terms or concepts related to the course, or even a guide to a major course concept
  • Maintaining a collection of links where the instructor and students can post, comment, group or classify links relevant to the course
  • Building an online repository of course documents where instructors and students can post relevant documents
  • Creating e-portfolios of student work

Wikis work best when individual authorship is less important than the outcome that is created. Also, wikis are most appropriate for content that doesn’t need to be protected from accidental editing.

Curious about how other instructors are using wikis? Take a look at these real life examples:

  • Chris Paris, lecturer at Vanderbilt Divinity, used a wiki in his “Bible in American Culture” class as a way to have students share pop culture references to the Bible, creating a shared class resource. In his “Literary Analysis of the Hebrew Bible” course, he asked students to take turns taking notes on class discussions and to share those notes on the class wiki. See more about his wiki use here.
  • Lou Rossi, Professor at the University of Delaware, used wikis in his Calculus undergraduate course and his Applied Mathematics graduate course. Using a wiki helps students spend time on solving problems outside of the classroom in a motivating collaborative environment. Publishing in a wiki gets students aware of the fact that they are writing for an audience, which usually results in using common mathematical language and formulas instead of plain English. See more about his wiki use here.
  • Columbia University Lecturer Jutta Schmiers-Heller created two separate wikis (one in the fall semester and one in the spring semester) to help the same set of Intermediate I German language students practice and recycle vocabulary and grammar, and learn culture in a fun, interactive way. Both wikis were embedded in the course curriculum and used for specific projects.  See more about her wiki use here.
  • Associate professor of English at Barnard, Derrick Higginbotham, used his course wiki as a presentation space and tool for text analysis for students. His course assignments included a close reading of texts within the wiki followed by student discussion in the discuss section of the wiki page. In the discussion section of each page, students responded to each others thoughts and analysis of the text, thus creating discourse outside of class and fueling the discussion in class. See more about his wiki use here.
  • Professor Patricia Shapley of the University of Illinois Chemistry Department created a wiki with content developed from her undergraduate chemistry students. The site – Middle School Chemistry –includes nicely done lessons on chemistry-specific. Middle School Chemistry highlights a very public, outreach website use of a wiki system.
  • Ben Miller, of the University of New South Wales, was runner-up for the Edublog Awards 2009 award for Best Educational Wiki. You can see is wiki on Censorship and Responsibility here.
  • Ruth Page, of Birmingham City University, has written a case study on her use of wikis to support small group work. She provides insight on how she asked students to use wikis to summarize small group discussions, giving greater value to small group interaction and building an online archive of class activities. Read her case study here.

Why use a wiki?

One of the primary reasons to use wikis is because they help your students reach Bloom’s higher order skills – things like creating and evaluating. Additionally, wikis achieve many of Chickering and Ehrmann good teaching practices including cooperation between students, active learning, prompt feedback from peers, time on task, the articulation of high expectations, and support for diverse talents.

Practically, we also think that wikis are a good tool to use because access and editing can be controlled by the instructor thus making a wiki public or private. Additionally, wikis are accessible online and include user friendly features that require little training. It’s likely your students will know exactly what to do!

How to get started with wikis

There are a variety of free and easy to use wikis that make it quick and easy to get started using wikis.  For example, try starting with:

Each of these options has example wikis that you can view to get an idea of the possibilities the tool.

Once you’ve chosen a tool, you’ll also want to:

  1. Make instructions explicit and provide clear expectations
  2. Build in time for practice
  3. Publish due dates for multi-phase projects
  4. Start with a simple wiki assignment before attempting a large, collaborative project

What does the research say about wikis?

Research on wikis is still emerging, here we’ll provide a brief annotate bibliography of recent articles:

  • Bold, M. (2006). Use of wikis in graduate course work.Journal of Interactive Learning Research, 17(1), 5-14.In the “Use of Wikis in Graduate Course Work,” the researcher evaluates wikis as a viable tool for collaborative work.  Bold cites benefits of wikis including ease of collaboration (“A collaborative workspace that can display documents immediately, with a minimal working knowledge of HTML tags”) and ease of use (“wikis require little to no institutional support, financial or technical”). Further,  Bold believes wikis don’t just help the student learn the curriculum better, but they help the student learn how to improve their skills in online interaction.
  • Deters, F. Cuthrell, K., & Stapleton, J. (2010). Why Wikis? Student Perceptions of Using Wikis in Online Coursework.MERLOT Journal of Online Learning and Teaching, 6(1). http://jolt.merlot.org/vol6no1/deters_0310.htm
    Elementary education professors at a large southeastern College of Education conducted a study for the purpose of exploring student perceptions regarding the use of wikis in online instruction and potential uses for wikis in the K-12 classroom as perceived by respondents. Participants in the study were 40 students enrolled in 1 of 3 graduate level social studies methods courses. Data were collected using surveys and written reflections. Though students reported initial hesitation at learning a new technology, their overall experience using the wikis was positive. The students felt that wikis were a great collaboration tool. Principle themes that emerged from the data were the potential uses of wikis as instructional tools, potential uses for information dissemination, benefits or advantages to using wikis, and limitations regarding the use of wikis. The authors provide a list of questions developed as a result of the study that, when used prior to implementing wikis as a learning tool, will minimize the limitations associated with their use.
  • Elgort, I., Smith, A. G., & Toland, J. (2008). Is wiki an effective platform for group course work?Australasian Journal of Educational Technology, 24(2), 195-21.  http://www.ascilite.org.au/ajet/ajet24/elgort.pdf
    This study reports on students’ and lecturers’ perceptions of using wikis as a platform for conducting assessed group projects in two postgraduate Master’s level university courses. The results highlight the fact that student attitudes to group work, in general, are mixed, and that the use of wikis per se is not enough to improve these attitudes. On the positive side, students found wikis useful for arranging information and sharing knowledge, while instructors thought wikis made managing and marking group work easier  and  more  effective.  Other  issues  related  to  using  wikis  as  a  collaborative learning tool in higher education are also considered.
  • Ioannou, A. and ARtino, A. (2009). Wiki and Threaded Discussion for Online Collaborative Activities:  Students’ Perceptions and Use. Journal of Emerging Technologies in Web Intelligence, 1(1), 97-106. http://www.ojs.academypublisher.com/index.php/jetwi/article/viewFile/010197106/12
    Researchers used a wiki with 15 graduate students in an online course. Students worked on two different group activities, first using the threaded discussion feature and then using the wiki. The researchers then investigated students’ attitudes about their experience, as well as differences in their processes, after using each technology. The findings suggest that there are clear benefits and limitations inherent to both technologies. The threaded discussion tool was preferred, yet students recognized the potential of the wiki to support collaboration. Practical implications and future directions are discussed, including the need for instructors to support and encourage discussion as a complement to wiki writing, scaffold and model the use of wikis, and create sufficiently complex group tasks to help make wiki use attractive and appropriate.

Common Concerns

A common concern among instructors new to wikis (as with blogs!) is how to evaluate a student’s work. We suggest that before implementing a wiki project in your course, you develop a rubric and explain to students how you will be evaluating their contributions to the wiki. Take a look at some of the existing wiki rubrics, like this one, this one, or this one, and adapt it to fit your needs.

Consider how (or if) you will evaluate the wiki’s:

  • Content and writing qualityConsider if the content is interesting and engaging. Does it include images and videos or slideshows? Has it been proofread?
  • Use and accuracy of citations and referencesAre there links to reliable outside resources that document student thinking?
  • AppearanceIs the wiki easy to navigate? Is it organized?
  • Collaboration among your studentsThe wiki will provide you with clues about collaboration on the “Page History” – you’ll be able to see if the wiki has changed significantly over time as member of the course added new content or revisions to existing content.

As with other types of assignments and projects, the more clear you are with your expectations, the more likely students will be able to meet them. To this end, Dave Foord created a simple acronym to get good results with wiki projects: STOLEN.

S
Specific Overall Objective (Clear objective for the wiki, Understood by all, Not a “general” area)
T

Ideas for using blogs and wikis in your course from Duke Center for Instructional Technology
http://cit.duke.edu/2009/01/blogs-and-wikis-in-your-course/

Should you use a wiki or a blog?

Wikis are often compared to blogs because, in many ways, they’re similar: they’re easy to edit, are used to collaborate, and each is easy to set up.

The difference between a wiki and a blog is that wikis are designed for collaboration among groups of users. Anyone with the shared wiki password can edit the content on a wiki at any time. Wikis also provide discussion boards for every page, enabling users to engage in ongoing conversations about their developing project.

So how do you choose? We suggest that you consider what you’re hoping to achieve by using a technology in your course. For instance, are you wanting your students to write collaboratively or do you want submissions by a single author? For the former use a wiki, and the latter a blog.

Ready to get started?

The possibilities for using wikis to engage students both inside and outside of the classroom are immense.  Don’t hesitate to contact the CFT if you are part of the Vanderbilt instructional community and would like to talk to one of our consultants about incorporating wikis into your teaching.
