概要
There are two issues in evaluating multimedia authoring environments such as SHlVA: the effectiveness of the support for authoring and the educational effectiveness of courses designed with the system. There are few evaluation methods which have been specifically designed for authoring systems. The authors' approach is to use a variety of methods. For the usability of the interface, a variant of task-action grammar known as D-TAG was used to capture the display-oriented nature of the interaction, also think aloud protocols with members of the design team. Detailed observational studies with experienced authors using SHlVA addressed the functional model of authoring underlying the system. One unexpected finding was that experienced users developed a common library of 'cliches' of logical sequences of material identifiable from their visual patterns. They were also able to parse flowcharts rapidly, even when unfamiliar with the teaching domain. The spatial layout enabled authors to create a visual course structure of concepts and frames, and the overall visual appearance of the concept network appeared to strongly affect authors' predictions of the teaching sequence

Abstract: There are two issues in evaluating multimedia
        authoring environments such as SHlVA: the
        effectiveness of the support for authoring and the
        educational effectiveness of courses designed with
        the system. There are few evaluation methods which
        have been specifically designed for authoring
        systems. The authors' approach is to use a variety
        of methods. For the usability of the interface, a
        variant of task-action grammar known as D-TAG was
        used to capture the display-oriented nature of the
        interaction, also think aloud protocols with members
        of the design team. Detailed observational studies
        with experienced authors using SHlVA addressed the
        functional model of authoring underlying the system.
        One unexpected finding was that experienced users
        developed a common library of 'cliches' of logical
        sequences of material identifiable from their visual
        patterns. They were also able to parse flowcharts
        rapidly, even when unfamiliar with the teaching
        domain. The spatial layout enabled authors to create
        a visual course structure of concepts and frames,
        and the overall visual appearance of the concept
        network appeared to strongly affect authors'
        predictions of the teaching sequence
