In this case, the understanding skills of 7th graders at Middle School 3 Parongpong about the dangers of instant noodles. Table 3 below the average gain value is 0.656 (66%) which indicates interactive lecture method for socializing the dangers of consuming instant noodles is quite effective for 7th grade students of Middle School 3 Parongpong. The minimum gain value obtained is 0.48 (48%) and a maximum of 1 (100%). If the presentation value of N-Gain <40%, it can be said as an ineffective interpretation category (Anshori & Wulandari, 2020). The minimum N Gain value obtained by we is 0.48 (48%) it can be categorized as an effective interpretation. This is influenced by the students' knowledge which is quite low about the dangers of consuming instant noodles the students' pretest scores are relatively low. Then the interactive lecture method is effective so as to provide students with an understanding of the dangers of instant noodles which in the end students can work on post-test questions with the right answers and higher scores.
