Shorthand Instruction via Computer by C. Bruce Kavan & Leona M. Gallion Indiana State University Introduction A unique application of the computer to the classroom environment has been to utilize a computer-based system for writing instructional materials for beginning shorthand classes. This system is used to verify and statistically analyze instructional new-matter shorthand dictation materials which are vocabulary controlled. These materials are then used for instructional purposes in beginning shorthand classes. Research Basis Research1 has established that achievement in beginning shorthand increases with the use of vocabulary-controlled dictation materials. However, only a limited amount of this type of material is currently available. This may, in part, be due to the large expenditure in human capital necessary to construct, verify, and analyze dictation materials utilizing a limited or controlled vocabulary. To facilitate and encourage the preparation of vocabulary-controlled dictation materials, a computer-based system was designed and implemented at Indiana State University in the Fall of 1973. This system has been used subsequently in shorthand methods classes and workshops for writing new-matter vocabulary-controlled dictation materials. The Computer-Based System The computer-based system is built upon a word base dictionary composed of the 1500 most frequently used words in written business office communications as established by Mellinger.2 The other information in the word base dictionary was researched and compiled by the designers from the various shorthand publications. The dictionary for these selected words contained [image] a. the word image b. the lesson number in which the word could first be written in beginning shorthand c. the number of syllables in the word d. the word frequency grouping in hundreds e. the word type(s) - brief form, brief form derivatives, word endings, and word beginnings Design criteria for the system was based on the following two objectives: 1. To design the necessary computer software which comprises the components of the system. Each of these components or subsystems consists of one or more computer phases or programs. The objectives of the subsystem were a. to statistically analyze dictation material. b. to access the dictionary (see Figure 1 for sample page of the dictionary) c. to provide the working tools for writing dictation 2. To design a computer system with maximum simplicity of operation for use by the novice student user while simultaneously achieving maximum efficiency of computer resources. The system is used first to verify a passage of dictation material which has been coded for use in a specific lesson in beginning shorthand. If a word in the dictation passage is not in the dictionary or is a word that cannot be written either in or prior to the lesson introduction code, that word will be underscored by astericks in the output (see Figure 2). After all words in a dictation piece are only those among the 1500 most frequently used words and are those which can be written in either the introductory lesson or the previous lessons, the statistical phase will execute. The edited text image is then outputted into standard word groupings of 10 for constant-level dictation (indicated by /) and 20 for traditional dictation (indicated by /#/). (see Figure 3) The syllabic intensity of the passage is computed as well as the following statistics: percent of words from each lesson, percent of words in each hundred of the 1500 most frequently used words as well as the percent of brief forms, brief form derivatives, word endings, and word beginnings. Further, all words that can first be written in each of the lessons are listed as well as brief forms, brief form derivatives, word beginnings, and word endings (see Figures 4 to 8). References 1.
