The purposes of this research were: 1) to develop the database applications requesting the position of scouts at the National Scout Organization of Thailand (NSOT); 2) to validate the efficiency of the database applications; and 3) to measure the user satisfaction towards the database applications. Statistical tools used in this research are twenty – seven of scout supervisors one of personal staff one of system administrator and one of manager. By purposive sampling. Instruments used in the research are the development of database applications request the position of scouts at national scout organization of Thailand assessment form the effectiveness of the developed program and questionnaire to measure the satisfaction of the trial of the application developed. The research found that the efficient of the development of database applications at a good leve (X = 4.38) and the satisfaction of users was at very good (X = 4.60). Therefore the developed program can be applied to used to optimize the application for a position with scouts.

The purposes of this research were: 1) to develop web-based instruction (WBI) on CAI course using project-based learning technique; 2) to evaluate if the WBI meets an 80/80 efficiency criterion; 3) to compare the students’ learning achievements by pre-test and post-test; and 4) to examine student satisfaction towards the WBI. The sampling group selected by purposive sampling was 30 grade 12 students who registered in the 2nd semester of academic year 2012 at Sarasas Witaed Bangbon School. The research instruments consisted of ten units of WBI; a learning achievement test administered before and after the instruction; and the evaluation form of the student projects. The statistical tests employed to verify the efficiency of the WBI were the E1/E2 efficiency index and t-test. The result of this research found that the efficiency of WBI was 84.56/82.33 which was higher than standard criterion 80/80. There was significantly higher learning achievement of the students in the post-test than in the pre-test at .05 levels. The learners’ opinion after using the WBI was very satisfactory.

This experimental research had five objectives: 1) to develop Web-Based Instruction (WBI) on Computer Assisted Instruction Course Using Problem-Based Learning and Demonstration Technique; 2) to evaluate the efficiency of the developed WBI according to Meguigans’s standard; 3) to compare the students’ learning achievements by pre-test and post-test; 4) to evaluate the students’ practical work and 5) to measure the students’ satisfaction towards the WBI. The samples in this research selected by purposive sampling consisted of 24 under graduate students in Academic Year 2/2012 of Department of Computer Education Faculty of Technical Education King Mongkut’s University of Technology North Bangkok. The research tools consisted of six units of the WBI a student’s learning achievement test administered before and after learning with the WBI video demonstration and problem based questions. The statistic employed in this research were the Meguigans’s standard t-test mean and Standard Deviation. Research results showed that; 1) the efficiency of the developed WBI was 1.22 according to Meguigans’s standard; 2) the students effectiveness after using the WBI was significantly higher than before using it at .05; 3) the average score of the practical work was 88.68 higher than 80; 4) the students’ satisfactory was at a good level. In conclusion the developed WBI can be used for the target group properly.

The purposes of this research were: 1) to develop Web-Based Instruction (WBI) on “Kingdom of Ayutthaya and Kingdom of Thonburi”กusing student team achievement division technique; 2) to evaluate if the WBI meets an 80/80 efficiency criterion; 3) to compare the students’ learning achievements by pre-test and post-test; and 4) to examine student satisfaction towards the WBI. The sampling group selected by purposive sampling was 25 primary education (grade 5) students in the second semester of academic year 2012 at Wattrithosathep school in Phra Nakhon district Bangkok. The research instruments consisted of two unit of WBI; a learning achievement test administered before and after the learning; and the evaluation form of the student performance. The statistical tests employed to verify the efficiency of the WBI were the E1/E2 efficiency index and t-test. The research result revealed that the efficiency of the developed web-based instruction (WBI) was 84.00/82.80 which was higher than standard criterion 80/80 and comparative of student’s achievement it was found that the student achieved learning progress significantly level of .05. Finally it was found that the learners opinion after using the developed web-based instruction (WBI) was very satisfactory.

This study aimed to 1) the evaluation of the design of Local History WebQuest of Mathayomsuksa 1 students based on constructivism through online social network revealed a high level of quality (= 4.62 S.D.=0.35) 2) the participants who studied Local History by using WebQuest with constructivism through online social network for Mathayonsuksa 1 students showed a better learning progress for no less than 20% 3) the participants’ satisfaction toward studying Local History by using WebQuest of Mathayomsuksa 1 students with the model that has been developed reached a maximum ( = 4.57 S.D. = 0.69).
