This paper addresses the role of interaction and its role in second language acquisition Research:

Priority is defined by the text alternative computation algorithm. Name Computation An accessible name is computed using a number of methods, outlined below in the section titled Text Alternative Computation.

Description Computation An accessible description may be computed by concatenating the text alternatives for nodes referenced by an aria-describedby attribute on the current node. The text alternatives for the referenced nodes are computed using a number of methods, outlined below in the section titled Text Alternative Computation.

Text Alternative Computation The text equivalent computation outlined below is a description of how user agents acquire a name or description that they then publish through the accessibility API. Authors can use the current section as a guide for creating names and descriptions in their markup.

The text alternative is reused in both the name and description computation, as described above. There are different rules provided for several different types of nodes and combinations of markup.

Text alternatives are built up, when appropriate, from all the relevant content contained within an element. This is accomplished via rule 2C which is recursiveusing the full set of rules to retrieve text from its own children.

The text alternative for a given node is computed as follows: Skip hidden elements unless the author specifies to use them via an aria-labelledby or aria-describedby being used in the current computation. By default, users of assistive technologies won't receive the hidden information, but an author will be able to explicitly override that and include the hidden text alternative as part of the label string sent to the accessibility API.

For any non-skipped elements: Authors MAY specify an element's text alternative in content attributesused in this order of preference: The aria-labelledby attribute takes precedence as the element's text alternative unless this computation is already occurring as the result of a recursive aria-labelledby declaration in other words, aria-labelledby is not recursive when referenced from another element, so it will not cause loops.

However, the element's aria-labelledby attribute can reference the element's own IDREF in order to concatentate a string provided by the element's aria-label attribute or another feature lower in this preference list. The text alternatives for all the elements referenced will be computed using this same set of rules.

User agents will then trim whitespace and join the substrings using a single space character. Substrings will be joined in the order specified by the author IDREF order in the aria-labelledby attribute. If aria-labelledby is empty or undefined, the aria-label attribute, which defines an explicit text string, is used.

However, if this computation is already occurring as the result of a recursive text alternative computation and the current element is an embedded control as defined in rule 2B, ignore the aria-label attribute and skip directly to rule 2B.

For example, in HTMLthe img element's alt attribute defines a label string and the label element references the form element it labels.

Authors sometimes embed a control within the label of another widget, where the user can adjust the embedded control's value. For example, consider a check box label that contains a text input field: If the user has entered "5" for the embedded text input, the complete label is "Flash the screen 5 times".

For such cases, include the value of the embedded control as part of the text alternative in the following manner: If the embedded control is a text field, use its value. If the embedded control is a menu, use the text alternative of the chosen menu item.

If the embedded control is a select or combobox, use the chosen option. If the embedded control is a range e. Otherwise, if the attributes checked in rules A and B didn't provide results, text is collected from descendant content if the current element's role allows "Name From:The role of language in education "Miss Kelly said that when you talk to somebody it's like you're playing ball.

First the somebody asks you a question, and that means they throw the ball to you. Table 1: Social action types and examples of their use in multi-user games The results of the study indicate the possibility of using the model of interaction forms as a tool for structuring the data into coherent and descriptive categories.

Despite the large number of studies dealing with input and interaction in SLA, and, indeed, the wealth of information that such studies have provided, the precise role of interaction in actual development and internalization of L2 knowledge has continued to challenge researchers.
