This study investigated the Effect of Multi-Media Instructional Strategy on Academic Performance of Students in Radio, Television and Electronic Work Trade in Technical Colleges of Kano State. Quasi-experimental design was adopted. A sample size of 40 Technical College (NTC III) students participated in the study. Purposeful sampling technique was used to select two intact classes from two colleges. A validated 40 – items instrument from NABTEB standardized test was used to collect data on the students’ performance in the following topics; Radio Communication, Satellite Transmission / Reception and Television. To avoid bias, the researchers prepared lesson plans that were used for the teaching of the two groups. The teachers from the two technical colleges were trained on how to use the lesson plans and multi-media instructional strategy, so as to control variability in the instructional procedure in the study. Four research questions and one hypothesis were raised. The data was analyzed using SPSS, mean and standard deviation were used to answer the research questions while t-test was used to test the null hypothesis. Multi-Media instructional strategy improved the mean performance of the students in Radio, Television and Electronic Work Trade, as seen in the post-test mean performance of 46.75 as compared with pre-test mean performance of 25.75 respectively, for the experimental group. There is significant mean difference in the post-test academic performance of students taught Radio Communication, Satellite Transmission / Reception and Television using Multi-Media instructional strategy. Among the recommendations made was: Stakeholders in education should make available and encourage the use of multimedia instruction in technical colleges of Kano State by providing multimedia instructional tools.
Assessment of Digital Economic Trade on Consumer (Published)
Increasing volumes of e-trade contribute to motivation of consumers to obtain commodities and services in electronic space. At the same time, upsurge of e-trade determines rising scopes of shadow economy in respect of favorable conditions for traders and service providers to operate in e-space evading taxpaying. The purpose of the article is to identify the factors of digital shadow consumption. In order to fulfill the defined purpose, the empirical research – survey of consumers (e-trade participants) – was performed. The research of the scientific literature has revealed that thus far the problem of consumers’ participation in digital shadow economy has been basically analyzed focusing on the impact of e-payment systems on shadow economy. Nevertheless, the rapid spread of e-services determines the changes in the concept of shadow economy itself. It remains indistinct which features indicate whether economic activities performed in e-space should be accounted or not. Widely exploited e-spaces such as social network platforms, alternative future currencies, e-trade systems, cyber computer games or online gambling terminals generate turnover of real money (or its electronic equivalent), which is not officially accounted. The problem raised in this article is highly topical for Lithuania, where online networks as well as mobile connection systems are comparatively advanced (with reference to the data of Lithuanian Department of Statistics, the number of households possessing a computer and the Internet access made over 65% in 2013). Intense exploitation of advanced IT technologies and online networks is considered as a breeding ground for generation of digital economy, a part of which is presumed to be digital shadow. The results of the research have revealed that the most significant factors of digital shadow consumption include lower prices of products and services in digital black markets, unfavorable economic situation in the country, technological advancement, IT advantages, time saving obtaining a product/service in the local market and lack of opportunities to obtain a desired product in the local market. The majority of the consumers neither verify the status of a trader nor request (or not always request) purchase confirmation documents, which highly contributes to motivation of an illegal trader to maintain e-activities unregistered, this way escaping revenue taxation.
