The Comparative Effectiveness of Using Computer and Typewriter for Teaching word processing in business education or instruction generally, has often been a serious area of discourse among business educators, teachers and students. One of such areas of concerns has to do with the level of effectiveness in the various applications or skills of the computer by business education students. The problem is that at Federal College of Education Kano, the conventional method of teaching and learning is still in use for word processing in business education. This traditional method can no longer provide the students with the knowledge and skills needed to succeed in the contemporary world of works that exist in this 21st century. Among the objectives includes to determine the relative effects of the levelof skills acquired by business education students taught speed development in word processing using computer and those taught using manual typewriter in Federal College of Education, Kano. The theory adopted for this study is Bandura?s Social Learning (Imitative) Theory. This theory is adopted to this study base on the fact that the students learn by observing the teacher demonstrating or performing certain tasks with the computer and the typewriter; and after watching how certain skills are used, students then duplicate the act. The entire 160 NCE III business education students of Federal College of Education, Kano formed the population of the study. All the thirty (30) students in office option formed the sample for the study. This was then divided into two groups (male and female) with each group having 15 students. Data collection phase lasted for three weeks, where pre-test was given before exposing the students to the treatment variable (computer) and control variable (typewriter). Mean and standard deviation were used to answer all the research questions. To achieve this goal four research questions were raised to guide the study, while t-test statistics was used to test all the four (4) null hypotheses formulated to be tested at 0.05 degree level of xiv significance (p= 0.05). The analysis of the findings revealed among others that, students exposed to treatment to learn speed development performed better than students exposed to traditional manual typewriter. It was also found that, students exposed to computer performed better than those exposed to conventional typewriter in terms of learning speed development.
