Abstract:
The objective of this research were to 1) construct and evaluate an agriculturist pesticide usage training model for reducing impacts on health and environment, 2) compare knowledge attitude and practical skill for reducing pesticide usage before and after training from an agriculturist pesticide usage training model, 3) compare knowledge attitude and practical skill for reducing pesticide usage after training by a model in different education and agricultural occupation, 4) study the satisfaction of agriculturist pesticide usage training model for reducing impacts on health and environment and 5) study agriculturist behaviors after training through a training model. This research is research and development method. 3 phases of this research were as follows: Phase 1 construction and evaluation of training model. The populations were 56 experts of agriculturist trainer on pesticide usage from Phetchabun Public Health office and the samples were determined form Delphi Technique method by simple random sampling to obtain 17 experts. Research data was collecting by Delphi Technique method in three-round. The research instruments consisted of rating scale questionnaire with that the Index of Item Objective Congruence: IOC at the 0.77 level and the reliability significance of 0.73. The results were analyzed by percentage, mean and standard deviation. Agriculturist pesticide usage training model was synthesized by results of this process. Agriculturist pesticide usage training model was evaluated by rating scale questionnaire with that the reliability significance of 0.73. Results were analyzed by mean and standard deviation. Phase 2 trial and study satisfaction of training model. The samples were 30 agriculturists in Sithep District Phetchabun Province. The samples were determined form experimental research method by multi-stage random sampling and randomized into the one-group pretest-posttest design of experimental group. The research instruments consisted of knowledge pretest-posttest which the reliability significance of 0.60 and the discrimination ranging from 0.71 to 0.72, attitude pretest-posttest which the reliability significance of 0.73, practical skill pretest-posttest which the reliability significance of 0.73, questionnaire for satisfaction of an agriculturist training model which the reliability significance of 0.73. Results were analyzed by percentage, mean, standard deviation, t-test (Dependent) and F-test (Oneway ANOVA). Phase 3 study agriculturist behaviors after training one month. Collecting data by checklist behavior test which the reliability significance of 0.72. The samples were same group of phase 2. Result was analyzed by percentage mean and standard deviation.
The research findings were as follows:
1) An agriculturist pesticide usage training model for reducing impacts on health and environment generated from concept of group process, concept of adult learning, environmental education concept, and advance organizer concept. Principles of this model were creating concepts, creating knowledge and application of knowledge. 5 steps of an agriculturist pesticide usage training model consisted of (1) stimulating attention was preparing and appealing by description, (2) proposed new knowledge framework was presenting of all knowledge and benefits apply by description and group process, (3) emphasize knowledge was summary of knowledge or core knowledge by description and group process, (4) recognize and associate knowledge were creating profound awareness by reading thinking questioning and answering, (5) application and encouraging retention of knowledge were creating and understanding knowledge and transferring adoption by description, (6) assessment was creating meaning of knowledge by writing or recording. Should be training by training plans of a model which that training plans in specialty were consisted of content of knowledge, media and measurement. The quality of an agriculturist pesticide usage training model was at good level.
2) Knowledge attitude and practical skill on reducing impacts on health and environment of agriculturist pesticide usage in posttest were higher than pretest with significantly difference at 0.01.
3) Knowledge attitude and practical skill on reducing impacts on health and environment of agriculturist pesticide usage with different education and agricultural occupation were not different after training from agriculturist training model for reducing pesticide usage.
4) The satisfaction of agriculturist training model for reducing pesticide usage on health and environmental impacts was at a high level.
5) Agriculturist behaviors test after training through an agriculturist training model was at very good level.
