Before we nit pick…The only question we should be asking is “do we like the approach” Note that this is an extended checkpoint. So it is an opt-in checkpoint, that does not have to be appropriate to all pages. Let me explain the thinking behind it. We need to say things like “provide clear words” – but that becomes impossible to test. What I have done is asked people to use clear content and then defined what we can test about it. It is clearer and workes better then limiting the text of the requirement to what happens to be testable. Also note that some tests are more clear cut then others. I have tried to include some of each for each criteria. Final word. Don’t knock it unless you want to think of a better way to do it….. and now to the main............ 3-E1 [4.1 and 4.2] Provide an easily understandable form of the content Minimum Success Criteria for this Checkpoint Provide: 1. simple words 2. clear words 3. short sentences and paragraphs 4. coherence of flow of ideas 5. supplementary non text 6. indications of relative importance of sections of content 7. summaries 8. Testing Note: some conmen sense needed… The best way to test this checkpoint will be usability testing with low reading age audience. However as this is not always possible, the following tests have been included for each of the success criteria: · simple words –compare to a (public) low reading age dictionary (such as VOL top 1000 word). if a word does not exist in that dictionary, check to see if a word that does exist in that dictionary can be substituted without loss of meaning. Any words that are not in your base dictionary should be included in a glossary. When adding terms to a base dictionary ensure that you have provided a glossary which can be easily accessed from each page were the term is used. Technique example: do a thesaurus check, and see if any replacement words will fulfill the same function as the original word Note: you can take a standard low reading age dictionary, and supplement it, if necessary, with terms and words that are conmen within your field. For example the term accessibility is extremely common in the field of accessibility, but less common outside this field. · clear words unclear words (can be simple words) include conjunction and words that create semantic ambiguity – IE were the sentence can be understood two ways. For example: “it” “he” “she” “they” “with”… noun phrases, where nouns are strung together, are often not clear. Do not use known phrases of more then three nouns. (eg : “web content accessibility guidelines” should be “guidelines for writing accessibility content for the web” – only two nouns are next to each other..) noun phrases that are part of the jargon of your field can be used if added to the glossary Titles, headings and summaries are special cases of clear text. It is important that each is unique and makes sense when read out of context. When presented a mixed up list of titles and headers, you should be able to clearly associate each title with the content that it relates to. There should be a clear relationship between the text of each hyper link with the page that it goes to. Special care should be taken with form labels. Hear you should use active voicing and remove all ambiguities. Eg: “Enter applicant name” should be “enter your name” · short sentences and paragraphs A paragraph should have one idea, with each sentence conveying one individual point. To test this you can imagine you are making a “sound bite” for radio, or a note for revision in the margin. Can the paragraph be summarized by a phrase? If you were making a summarized form of the document – can each sentence be represented by a list item? Rule of thumb : double check sentence over 20 words. Check paragraphs of more then 5 sentences.Do not use careful of sentence over 35 words. Do not use a paragraphs of more then 7 sentences Rule of thumb : double check sentences with two or more conjunctions. (or, and …). Do not use sentences with four or more conjunctions. Rule of thumb: double check sentences with two or more comers.Do not use sentences that needs four or more comers. · coherence of flow of ideas Within a paragraph the sentences should flow and be well connected. When a new idea starts –it is time to start a new paragraph. Paragraphs within a topic should flow with a clear link. When a new topic starts it is time to start a new topic. Topic changes should be indicated through mark up. (such as with a new header) One can test for coherence by drawing a flow chart of the page content. Is the flow logical? Test coherence by stating the relationship between each paragraph and the next –If it is hard to do then the coherence is lacking. · supplementary non text A picture can be worth 1000 words, especially to people with low reading ability. When performing usability tests, ensure that all steps required by the main goals of the site are supplemented with icons. If you do not have usability testing goals, then supplement 1. Help 2. Contact us 3. Important 4. Danger (danger is any section of content about how harm can come to the user –physical, financial or other) In forms that are required for some of the core site functions (an on site search form is helpful - a login in form may be core) add icons were 1, you are asking for something you can point to (such as a credit card expiry date) 2, there is a representation available (a house for address, or a telephone for phone number.) For example Credit card number can be accompanied by a picture of the credit card with an arrow pointing to the position of the number · indications of relative importance of sections of content the relative important of site content should be made available so that it can be presented differently. For example the user may want a summarized form of the site, or all important information marked in a bright color. · provide summaries. A summary of content should be made so that the user know what is coming in the next section of content. A simple page (such as an ecomerse site) a can be summarized using the page title and description. For example title:” our brand swimwear page” Description “ see all our swimsuits for both adults and children” Note to use the title and description meta data as a summary, each tile and description must be clear and unique for each page of your site. The summary must represent the main flow of ideas within the page. Pages that contain a complex flow of ideas include, guidelines, academic work, articles and discussions. Such as pages require additional summaries to be provided.
