The effectiveness of a proposed educational program based on the principles of green chemistry in developing scientific awareness among first-year secondary school students in Shabwa Governorate, Republic of Yemen
This study aimed to measure the effectiveness of a proposed educational program—based on the principles of green chemistry—in developing scientific sense among first-year secondary school students in Shabwah Governorate, Republic of Yemen. The study employed a descriptive-constructive approach, as well as a quasi-experimental design (a single-group, pre-test/post-test model) to evaluate the effectiveness of the proposed program. The study sample consisted of 60 first-year secondary students from Bayhan Secondary School, located in the Bayhan District of Shabwah Governorate, Yemen. The researchers developed an instrument to assess the cognitive aspects of scientific sense; after verifying its validity and reliability, it was administered to the sample both before and after the intervention. The study reached the following conclusions:
1. The final version of the proposed educational program, based on green chemistry principles, consists of four study units, comprising a total of 17 lessons (with each unit containing four to five lessons).
2. The selected study unit from the program covers three main topics—subdivided into several subtopics—distributed across eight sessions (two sessions per week), in addition to six sessions dedicated to the pre-test and post-test assessments.
3. There are statistically significant differences (at the α ≤ 0.05 level) between the mean scores of the first-year secondary students in the pre-test and post-test, both for the overall cognitive aspects of scientific sense and for each individual component of the test, with the results favoring the post-test.
In light of these findings... A set of recommendations was developed, most notably the enhancement of science curricula in general—and chemistry curricula at the secondary school level in particular—to align with scientific advancements related to green chemistry and its applications.
