The findings show that experts have consensus agree on all 25 items which exceeds 75%, and all defuzzification values for each item exceeds the value of a-cut = 0.5. That means all those items are accepted by the experts. Fuzzy Delphi Method enhanced the accuracy of the questionnaire about Geo-Education module. This study has provided preliminary information on Geo-Education module aspects that need to be focused on Primary; Natural Ecosystem; Issues and Problems; Sustainable Lifestyle; and Cross-Curricular in the process of developing effective teaching and learning modules.
