The effectiveness of microcontroller instructional system through simulation program method by using trainer kit
No full textThe study was to test the learning effectiveness of program simulation method by using the trainer kit in Microcontroller System courses. The study was conducted to the students who took the microcontroller system courses in the academic year of 2013/2014. The students who took the course were divided into three groups and each of the group served as: (1) the experimental group; (2) control group; and (3) test instrument group. The learning outcome variables (Y2) and the awareness of thinkings (Y1) served as the dependent variable; on the other hand, the motivation (X1) and the creativity (X2) served as independent variables. The data analysis was done by performing the Analysis of Variance (ANOVA) and the Multivariate Analysis of Variance (MANOVA) in order to see the differences in the learning outcomes and the level of students thinking. The results of the study showed that there have been significant differences in the level of metacognition and the level of learning outcomes competence on the program simulation method by using the trainer kit on microcontroller systems course in comparison to those who were not using it
Factors discouraging students from schooling: A case study at Junior Secondary School in Laos
No full textThis study is aimed at exploring and describing the factors discouraging Laos students from schooling at a secondary school in various contexts such as classroom and school, individual student, family, and community contexts. Descriptive qualitative approach was used, and the framework of the study was formulated around the aspects of school and classroom situation, principal\u27s management process, teachers\u27 teaching organization and performance, parents\u27 involvement and perception, and community\u27s involvement and perception. The data were collected through observation, document analysis, and interview from 10 students, six teachers, one principal, one vice principal at Phonsyneua Junior Secondary School, and seven parents whose children were studying at this school. The finding shows that among the factors involved in students\u27 schooling at secondary school, several factors discourage them. The teachers\u27 performances were not perfect yet and some students\u27 competency was not qualified enough. The students\u27 parents were not highly committed and involved in their children\u27s schooling. The community had little trust in schooling since they perceived that schooling costs a lot of money. To improve these discouraging factors, several actions should be taken into consideration. The principal should ask all the teachers to communicate the vision and missions to the students, or the vision and mission should be published and socialized in the school. The observations on teachers\u27 instruction should be done by both the principal and senior teachers

The Effectiveness of Problem Posing Approach in Terms of Achievement, Mathematical Connection Ability and Mathematical Disposition in Mathematics
Abstract
The aims of this study were to describe the effectiveness of problem posing approach, the conventional approach, and the comparison of the effectiveness between problem posing approach and conventional approach in terms of achievement, mathematical connection ability, and mathematical disposition. The research design used quasi-experimental.. The population consisted of all 8th grade in State Junior High School 1 Tempel Sleman consisting of six classes. There were two classes involved. Class VIII D as the experiment class was taught using problem posing approach, while class VIII A as the control class was taught using conventional learning. The data collecting techniques were a test and non-test whereas the instruments were used to collect the data consisted of a mathematical achievement test, a mathematical connection test and a mathematical disposition questionnaire. The data were analyzed using MANOVA test, one sample t test, and two samples independent t test. The result of the study by using significance level 5%, showed that the problem posing approach was only effective in terms of achievement and mathematical connection ability. Conventional approach was not effective in terms of student\u27s achievement, mathematical connection ability and mathematical disposition. Problem-posing approach was more excellent compared to conventional learning in terms of student\u27s achievement ability and mathematical connection ability.
