Abstract:
The objectives of this research were to 1) study the factors of life skills of lower secondary school students, 2) develop instructional model of life skills of lower secondary school students, and 3) study the results of the instructional model to develop the life skills of lower secondary school students. The research procedure consisted of 3 phases as follows: Phase 1. Study the factors of life skills of lower secondary school students. The samples of this research were 1,800 lower secondary school students in the first semester of the academic year 2013 from 12 Colleges of Dramatic Arts under Bunditpatanasilpa Institute, Ministry of Culture, defined by the rule of structural equation model analysis using a multi-stage random sampling. The instruments used in collecting data were in-depth interview and a five-rating scales questionnaire with the reliability level at 0.86. The data were collected by Booklet Matrix Sampling. The statistics for data analysis were to fine reliability of the instruments, exploratory factor analysis and confirmatory factor analysis by using LISREL program Version 9.10 with activation code: 9F00-0DE7-2F4E-D2CF. Phase 2: Develop instructional model of life skills of lower secondary school students. Five experts checked the appropriateness and feasibility of the developed model in phase 1, including the results of the synthesis of the concept and related theories. The results found that the developed model was appropriate and had the feasibility to be used in the development of life skills of lower secondary school students. Phase 3: Study the result of the instructional model to develop the life skills of lower secondary school students. The experimental research methodology was carried out by the time-series design. The samples of this research were 59 Matthayomsuksa 2 students in the second semester of academic year 2013 of Lopburi Dramatric Arts College, Bunditpatanasilpa Institute, Ministry of Culture derived from multi-stage random sampling. Simple random sampling was used to divide students into 2 groups, 28 in a control group and 31 in an experimental group. The study lasted 12 weeks. The data were collected by life skills test and students behavior observation form. The statistics for data analysis were mean, standard deviation and Repeated Measures One-Way ANOVA for hypothesis test.The results were as follows: 1. Life skills were composed of 4 factors: thinking skill, mind skill, action skill and social skill. The construct validity of structural model which was analyzed by the exploratory factor analysis could be presented by the goodness of fit index congruence of chi-square test: c2 = 145.96 df = 75 p-value = 0.00000 RMSEA = 0.023 GFI = 0.99 AGFI = 0.98 CFI = 0.99 RMR = 0.36 SRMR = 0.020 and CN = 1,312.31.2. The instructional model of life skills of lower secondary school students was the model of activities that was not based on content of the course to develop 5 social skills of lower secondary school students including creative thinking skill, communication skill, interpersonal skill, social responsibility skill and cooperation skill. The Learning activities contained 6 sequential steps: 1) motivation 2) experience 3) participation 4) presentation 5) summarization and 6) application. The life skills test and students behavior observation form were used in measurement and evaluation.3. The results of the instructional model of the life skills of lower secondary school students found that the students who learned by the instructional model of the life skills had higher social skill than the students who learned by the traditional approach at a statistically significant .05 level (F = 620.31). The social skill behavior after the experiment was higher than before the experiment at a statistically significant .05 level (F = 6022.27).
