Abstract
The aims of this study were to 1) develop instructional media innovation from tablets with microcontroller boards for computing science and 2) study satisfaction after used it. The target groups consisted of 10 people in a lesson study team and 22 third-grade students in the first semester of the academic year 2023 from small-sized public elementary school in Phitsanulok Province. This study was a mixed-methods research. The research instruments , including 1) the instructional media innovation from old tablets with microcontroller boards 2) a quality assessment
3) a performance assessment and 4) a satisfaction questionnaire. Data analysis involved the use of statistics such as IOC, averages, standard deviations, frequency and tables to present the gathered information.
The findings of the study showed that 1) The instructional media innovation is classified as a semi-concrete medium in the form of Unplugged Coding, which receives data from IDE program on an ESP8266 microcontroller board and displays it on an old tablet screen through the App Inventor program, which can be installed in the form of an APK file. It is divided into two aspects: (1) Data transmission: it was found that 28 command cards transmitted data with 100.00 % frequency, and (2) Usability: the media can be effectively used in all three activities with 100.00 % effectiveness. The quality of the instructional media innovation achieved an IOC value greater than 0.67 for all items. 2) The overall assessment of teachers’ satisfaction level is at the highest
level. It encompasses three aspects, namely: (1) the quality of teaching and instructional management ( = 4.77, S.D. = 0.54) (2) the usability (
= 4.55, S.D. = 0.63) and (3) the design (
= 4.33, S.D. = 0.54), respectively. 3) The overall assessment of students’ satisfaction level is at the highest level. It encompasses three aspects, namely: (1) the quality of teaching and instructional management (
= 4.70, S.D. = 0.52) (2) the usability (
= 4.61, S.D. = 0.61) and (3) the design (
= 4.50,S.D. = 0.66), respectively.
