A report on the development of an instructional unit entitled Signals across the waves : Marconi's reception of the first transatlantic wireless signals

Abstract

The purpose of this study was to develop instructional material on Guglielmo Marconi's reception of the first transatlantic wireless signals for use as supplementary material for the Grade Five Newfoundland history text. -- It was the researcher's contention that few materials were readily available on this topic at this grade level. A review of existing materials both print and non-print, confirmed that this was the case. -- A survey of thirty-five teachers of history in Grade Five was conducted. The findings indicated that insufficient resource material was available to teachers, and that a supplementary unit on Marconi would be welcomed. The preferred medium of instruction was the sound filmstrip. -- An instructional package was produced with formative evaluation carried out at various stages by learner specialists, media specialists, a content specialist and Grade Five students. A summative evaluation involved a three-group design with analysis of results including comparisons of means, examination of percentage of items correct and an item analysis. The results proved to be quite favourable. -- In conclusion, a slide-tape programme entitled Signals Across the Waves: Marconi's Reception of the First Transatlantic Wireless Signals is now ready for use in the Social Studies Programme for Grade Five.
