Content preparation: Factor structure and delivery
Abstract
In a sequence of three studies the nature and characteristics of Content Preparation was investigated. Each of these studies is presented below. Study 1 demonstrates the development and validation process of tools to design and evaluate information usability of websites. Based on background literature, a 100 item questionnaire with two scales—satisfaction and importance—was developed and administered to 322 participants. The results of exploratory factor analyses reduced the size of the questionnaire from 100 items to 40 items and identified seven factors for information satisfaction and eight factors for information importance. The seven factors for information satisfaction are General Product Description, Member Transactions, Shipping, Secure Customer Service, Company, Durability, and Price. The eight factors for information importance are Purchase Advice, Product Inventory, Short Product Description, Member Transactions, Shipping, Secure Customer Service, Company, and Durability. Two experiments were conducted to investigate the impact of specific components of Content Preparation in information technology. The first experiment, derived from Study 1 results, examined presentation mode, error type, and the interaction of these effects on customer satisfaction, usefulness, and loyalty. Twenty-seven participants evaluated sequences of common error messages presented in three modes (i.e. Text, Iconic, and Video) while browsing e-commerce websites. Results provide guidelines describing which presentations are best for presenting error messages in different scenarios. The second experiment applied Content Preparation to classroom lectures. Its objective was to assess the comparative effectiveness of PowerPoint™ presentations versus Traditional blackboard—based lectures. Data was collected from 62 students via quiz and questionnaire. Results indicated that students recall 28% more of the content presented verbally in Traditional class presentations than in PowerPoint™ presentations; but prefer, by 17%, PowerPoint™ presentations over Traditional presentations.
