Comparison of online training courses on wastewater treatment technology and community waste disposal.

Abstract

The purpose of this research was to study and compare online training courses by measuring knowledge. Understanding before and after training and finding the relationship between the age range of the participants in 2 courses 1) Wastewater Treatment Technology Course (10 items) and 2) Community Waste Disposal Course (20 items) with a total of 177 samples. The instrument used was a 5-level estimation scale questionnaire to verify accuracy (IOC) Between 0.80-1.00 and the confidence value of Cronbach's alpha coefficient was 0.97. The statistics used in the research were mean (𝑥̅) and standard deviation (S.D.). Comparison of 2 groups of variables by Using a t-test, one-way analysis of variance.

The results showed that the samples used in this research were Participants through the online system Community wastewater treatment course and community waste disposal courses of the Technology Transfer Center according to royal initiative Northeast by simple random sampling of not less than 177 samples calculated from the ready-made tables of Krejcie & Morgan at a confidence level of 0.05

(1) The relationship between the age range that is suitable for using the course for the benefit of the participants through the online system is at a moderate level and after the overall training at a high level In addition, the age appropriate for the course to be useful is the age range of 24-25 years, both before and after training. The community waste disposal technology course has knowledge. Overall understanding before and after training at the same level and the age range suitable for using the curriculum before training is 18-19 years old and after training is 24-25 years old. The sample group in each age group suitable for the program's utilization overall had no significant difference in knowledge and understanding at the 0.05 level of confidence.

(2) Compare and measure knowledge and understanding before and after the training course on wastewater treatment technology and community waste disposal. Trainees have knowledge overall understanding moderate As for the training via the online system, the community waste disposal technology course. Participants are knowledgeable overall understanding at a high level Therefore, it can be concluded that the overall knowledge of online training The understanding of the participants in the two courses when comparing before and after the training of each course was not different.
