การเปรียบเทียบผลการระลึกได้ทันทีของนักศึกษาที่ฟังเทปบันทึกเสียง ด้วยความเร็วปกติและด้วยความเร็วแบบเร่ง / บุญชัด เนติศักดิ์ = A comparison of immediate recall effects of students listening through normal speed audio-tape and variable time compressed speed audio-tape / Boonchat Netisak
Purpose The purpose of this study was to compare the immediate recall effects of students listening through normal speed audio-tape and variable time compressed speed audio-tape. Procedure The samples were 100 male and female first year studnets at the higher certificate of education level and the degree of education level studying in the second semester of 1981 academic year at Lampang Teachers College. The students were randomly selected and divided into 4 groups, 2 groups of students having high learning ability and 2 groups of students having low learning ability. The groups were called “High A”, “High B”, “Low A” and “Low B”. There were 25 students in each group. The students in “High A” and “Low A” listened to the same tape recorded at a normal speed whereas “High B” and “Low B” listened to the recorded at a compressed speed; the rate of reduction in listening was 27%. Three short passages selected from science and technology magazines were taped. Before the experiment being done, the students were tested and practiced to listen to tapes recorded at the same speed as the experimental tapes. While being experimented, the students listened without writing down or repeating what they heard. When the tapes finished the students did the test immediately. The different scores between the pre-test and the post-test were interpreted in terms of a statistical mean and 2 ways analysis of varience. Then the significant difference between each pair in each group was tested by Tukey’s HSD. Results 1. No statistically significant difference were found in comparing the immediate recall effects between “High A” and “High B”. 2. Statistically significant difference were found at .05 level in comparing the immediate recall effects between “Low A” and “Low B”.
