    Video analysis : A qualitative tool for investigating students' learning in a constructivist-oriented multimedia in a science classroom

    A new software package VideoSearch, a Macintosh multimedia research tool for analysing digital video was used to analyse classroom observations. VideoSearch can digitise video from a video cassette recorder or video camera and store it on a computer as a QuickTime movie. Texts can be attached to each instance within an episode and this text can be searched. Episodes in this movie can then be coded for analysis by means of user defined categories. Analyses of three types of episodes from video segments are presented and discussed in order to investigate students' learning. Episodes from video segments include students working in pairs conducting investigations based on an inquiry- based multimedia program, students presenting their experiences of their process of investigation and the researcher probing the students' reflections on their learning during an interview. An advantage of working with the digital video analysis is greater access to fuller context for qualitative data analyses. This allows for a better understanding of the social processes of students' learning. However, the time required and the level of intensive analysis may make it a difficult process to undertake

    Pattern languages in HCI: A critical review

    Get PDF
    This article presents a critical review of patterns and pattern languages in human-computer interaction (HCI). In recent years, patterns and pattern languages have received considerable attention in HCI for their potential as a means for developing and communicating information and knowledge to support good design. This review examines the background to patterns and pattern languages in HCI, and seeks to locate pattern languages in relation to other approaches to interaction design. The review explores four key issues: What is a pattern? What is a pattern language? How are patterns and pattern languages used? and How are values reflected in the pattern-based approach to design? Following on from the review, a future research agenda is proposed for patterns and pattern languages in HCI
