Web-Based Application of Electrical Installation and Maintenance Work Intelligent Tutoring System in West African Technical Colleges (Published)
Digital technology has provided an effective instructional delivery paradigm in technical education, which enhances the attainment of cognitive, affective, and psychomotor skills. The purpose of an intelligent tutor as a computer-aided learning system is to complement teacher activities by providing students with relevant information via a computer interface. This study aims to develop a web-based artificial intelligence tutoring system for practical electrical installation and maintenance work for teachers in Nigerian technical colleges. Specifically, the study sought to develop the Electrical Installation Intelligence Tutor (EIIT) software, determine the effect of the tutor on students’ acquisition of practical skills, and determine students’ interest in studying electrical installation. Two research questions and two null hypotheses guided the study. The study adopted R&D design. From a population of 263 electrical installation students, 20 were selected to use the stand-alone method and 18 to use the web-based method. The instrument for data collection was lesson plans based on three of the components of electrical installation namely, domestic and industrial installation, and cable jointing topics as listed in the National Board for Technical Education syllabus. An achievement test and interest survey were developed and built into the software. Validation of the content of the achievement test was determined to be 0.67, while the internal consistency of the survey was 0.89. The null hypotheses were tested through analysis of covariance at the 0.05 significance level. Results show that use of the tutor caused the students to be more highly interested and motivated. Thus, the authors recommend intelligent tutor
Attitudes of Teachers Towards Application of Item Response Theory in Technical Colleges in Rivers State (Published)
This study investigated attitudes of teachers towards the application of item response theory (IRT) in the technical colleges in Rivers State. It is intended to ascertain the influence of these teacher-related factors on testing processes using IRT in these institutions. Five research questions were asked to guide this study and five null hypotheses were formulated and tested. Cross-sectional survey research design was adopted in this study. The population of this study comprised all the 424 technical teachers in the 15 technical colleges in Rivers State. The study used stratified random sampling technique to draw the sample of size of 212 out of the population. The instrument for data collection was a self-designed Likert type (five response level) questionnaire titled,“Survey of Teacher’s Attitudes Towards Application of Item Response Theory (STATA-IRT), with a reliability coefficient of .86. Correlation analysis was used to answer the research questions and multiple regressions, R, was used to test the null hypotheses at 0.05 alpha level. It was found from the overall result, that strong linear relationship exists between attitudes of teachers and the application of Item Response Theory in Technical colleges Rivers State. It was also found from the multiple regression results that the attitudes of teachers are predictors of effective application of item response theory in the technical colleges in Rivers state.
Assessment of the Adequacy of Material Resources for Effective Teaching of Building Technology: A Panacea for Promoting Entrepreneurial Skills in Rivers State Technical Colleges. (Published)
The global economic pressure to compete on cost, service and quality has resulted in the agenda of the Government to re-focus the economic development processes to increase and nurture intellectual capital and entrepreneurship for economic transformation in Nigeria. This study was designed to assess the adequacy of building material resources for effective teaching of building technology: a panacea for promoting entrepreneurial skills in building technology in Rivers State technical colleges. The population for the study was 90,made up of 26 technical teachers, four technical instructors and 60 building technology students in the four technical colleges in Rivers State .A questionnaire based on five point Likert- scale was used as the data collection instrument .mean was used to analyze research results. The findings of the study are (1) workshops are not well equipped with sufficient tools and equipment. (2) lack of in-training of teaching personnel (3) inadequate power supply to the workshops. The study recommended the following: there should be adequate supply and proper maintenance of tools, equipment, and workshops. Government should ensure steady power supply to the workshops for practical and there should be in-service training for teaching personnel through seminars and workshops.
