This study aimed to develop a localized learning module for Alternative Learning System (ALS) Learners focusing on the improvement of critical thinking skills, which is the overall purpose of their science learning strand. In developing the localized module, the researcher gathered data about the locals knowledge of herbal medicine through interviews and used resources to relate the content to the learners local setting and curriculum. The samples of the plants they commonly use were sent to the University of the Philippines-Diliman Campus for plant authentication. After the module was developed, it was sent to thirty (30) validators, including ALS and science teachers for validation. Based on the mean and standard deviation of the validators responses, it was concluded that the localized module is highly acceptable in terms of its content, format, presentation and organization, assessment tools, usability, adaptability, and consistency. Moreover, the junior high school ALS learners also evaluated the developed localized module according to its text, illustrations, design, and layout. Using Independent-Samples Mann-Whitney U Test and Independent-Samples Kruskal-Wallis Test, it was found that there was no significant difference in the student-respondents perceived level of acceptability of the localized module when grouped according to sex and age. The following recommendations are suggested according to the findings and conclusions of the study: ALS learners may use the localized learning module as supplementary learning material ALS science teachers may also develop learning modules with localized content and future researchers may utilize the localized learning module in subsequent studies related to this topic.
