Double‐fading support — a training approach to complex software systems

Abstract A new approach to software training is presented, the so‐called Double‐Fading Support (DFS) approach. According to this approach, which is based on Carroll's training‐wheels idea and on cognitive theories of skill acquisition, two types of user support when learning to use a complex software system — locking the software's functionality and detailed guidance — are faded out gradually during the training course, so that the learners are able to use the complex software with minimal instructional support at the end of the training. Two 30‐hour training experiments with two different CAD software systems and CAD‐inexperienced university students were conducted. The results of Experiment 1 with 88 participants indicate the effectiveness of the DFS‐approach for CAD software with a deeply structured menu system. Participants working with the initially reduced software outperformed participants of the full software functionality group; additionally, participants of the slowly faded guidance group outperformed participants receiving medium, fast or no fading of guidance at all. Results of Experiment 2 with 120 participants, however, indicate less effectiveness of the DFS‐approach for an icon‐based CAD software in which most of relevant functions are permanently visible to the user. It seems that the two factors (fading out the locking of software's functionality and fading out detailed guidance) overcompensate each other.

Effects of real‐time visual feedback on pre‐service teachers' singing

This pilot study focuses on the use real‐time visual feedback technology (VFT) in vocal training. The empirical research has two aims: to ascertain the effectiveness of the real‐time visual feedback software ‘Sing & See’ in the vocal training of pre‐service music teachers and the teachers' perspective on their experience with VFT. Forty participants from an undergraduate music teacher education programme were randomly assigned to three groups. The first two groups were assigned the teacher and student versions of Sing & See, respectively, and the third group served as a control group without access to the software. The experimental groups were given 12 weeks to use the software for vocal training on a self‐regulated basis. The technique of complex selections (TCS) was designed to assess the pitch accuracy and richness of vocal timbre. Pre‐ and post‐test singing tasks showed that the participants from the experimental groups significantly improved their vocal timbre. A questionnaire survey conducted after the training period found that most of the participants in the experimental s were positive about the effectiveness of VFT software in vocal training. As future leaders in the implementation of music education technology, pre‐service music teachers expressed a positive attitude towards the use of VFT as a technology‐enhanced learning (TEL) component in music education.

A NEW LOOK AT DOCUMENTATION AND TRAINING

Users need quality documentation and training. A technical communicator can be an indispensable communications analyst and problem solver for an organization, helping to analyze user requirements, clarify the documentation process, develop information products, and provide computer training. By assisting IS management in solving increasingly complex communication problems, this person can also shed the one-dimensional image of the technical writer who works solely as a software documenter at the end of the development process.     

A SGeMS code for pattern simulation of continuous and categorical variables: FILTERSIM

The new multiple-point geostatistical algorithm (FILTERSIM), which can handle both categorical and continuous variable training images, is implemented in the SGeMS software. The spatial patterns depicted by the training image are first summarized into a few filter scores; then classified into pattern groups in the filter score space. The sequential simulation approach proceeds by associating each conditioning data event to a closest pattern group using some distance function. A training pattern is then sampled from that group and pasted back onto the simulation grid. Local multiple-point statistics carried by patterns are captured from the training image, and reproduced in the simulation realizations. Hence complex multiple-scale geological structures can be re-constructed in the simulation grid, conditional to a variety of sub-surface data such as well data and seismic survey.
