Group Learning and career and technology.Mathayom1 to develop a model of learning. The efficiency of 80/80 and ducation.Satisfaction of students about learning by developing interactive learning building.Knowledge, information technology course one media tablet. The population were students at the Royal College Creek High School first semester one. 2558 Year 5 classroom number 173 is a randomized sample Simple (Simple.Random Sampling) by lot is at. Half of 39 study results are as follows. 1 . interactive learning knowledge. 1 Course Technology Media tablets on information technology. Found to be effective (E / 1E (2is equal. 81.27 / 85.58, which is higher than a predetermined threshold is .80/80 2 . The average score for the class different from the average pre significance level..01 3 . The percentage of students passing the threshold is set at 93.34 percent, higher than a predetermined threshold is 80 percent of students scored 26.66 percent of the total score. 4 . The index of the effectiveness of interactive learning knowledge Course.Technology first media tablet is equal to 0.5513, which means that students have much more knowledge. 55.13 percent 5 . The mean and standard deviation. The coefficient of variation of the latter is equal to 28.62, 1.90 and 0.11, which meets the criteria set average 80 percent of the full standard deviation lower. And coefficient of variation of less than 10 points. .6learning with interactive learning knowledge. Course Technology1 tablet of information through the media.
