Abstract

Rasbora philippina is an endemic species in Mindanao Island, Philippines. Its reproductive biology remains unstudied despite its economic importance to the local inhabitants of the lake, the Subanen tribe. Due to its marketability, Rasbora faces local threats. Thus, the formulation of fishery management and conservation recommendations is highly recommended. A research-made survey was used to interview fishermen in the lake, and fish samples were collected using a seine net with a catch per unit effort of three or four from March to May 2019. Water samples were collected using a Niskin water sampler at 1 m and 15 m depths during the same period. The reproductive biology of the fish was determined using the following data: sex ratio, maturity stages, age and population structure, fecundity, gonadosomatic index, and length-weight relationship. During the study period, the water quality was highly variable, still in good condition, and could still support the population of R. philippina. There were 31 male and 403 female individuals with a mean fecundity of 2,645.67, suggesting that there were more females than males, compensating for the low fecundity of R. philippina. The species does not spawn continuously, as mature individuals were absent throughout the study. However, this species is continuously recruited due to the presence of juveniles in the entire sampling period. Peak spawning was in early and mid-March and mid-April. Based on the results, we suggest that the open fishing season should be in early April, late April, and the third week of March, while the closed season for fishing would be in early March and late March. Thus, the management and conservation of R. philippina should always include careful consideration of the facts presented in this present work.

Abstract

In times of rapid change and persistent learner challenges, continuously updating curriculum materials is essential. The growing problem of plastic pollution stresses the need to integrate citizen science into education to ensure relevance, engagement, and contextual application. This study developed and evaluated a module-based curriculum material that embeds citizen science into the Science, Technology, and Society (STS) curriculum, focusing on the assessment of coastal plastic waste. An initial needs-assessment among STS instructors revealed strong agreement on developing localized, citizen-science-based materials to enhance environmental awareness. Quantitative findings demonstrated high acceptability from both experts and students. Expert evaluation yielded “Fully Acceptable” ratings in all categories, with visuals rated “Very Good (Acceptable)” (Mean = 3.67), indicating strong quality and minor areas for improvement. The Students’ Involvement Index (SII) of 1.07 reflected effective learner engagement, while the Fry Readability Graph placed the module at the college reading level. The Communication Index (CI) ranged from 0 to 0.01, with a CI of 0.01 indicating fair comprehensibility—acceptable but suggesting refinement of scientific terms. Qualitative feedback from students showed that the module was engaging, meaningful, and applicable to real-world issues. Overall, integrating citizen science into the STS curriculum proved to be a viable and impactful strategy for promoting environmental literacy, fostering active participation, and strengthening contextual understanding of coastal pollution among undergraduate learners. Future work should focus on improving visuals and clarity, expanding instructional resources, enhancing teacher training, and conducting broader and long-term implementations to strengthen its educational impact.

Abstract

COVID-19 pandemic exhausted the learning resources in the educational system of the Philippines. This situation called for learning materials to supplement the teaching-learning process while in distance education. Hence, this paper utilized asynchronous video lectures (AVL) infused with online learning simulators (OLS) to supplement learning approaches in teaching cell division. Specifically, the goal of this study is to asses the students’ motivation as well as their common misconceptions in learning cell division. Using students’ motivation towards science learning (SMTSL) questionnaire, it was found that the learners are moderately motivated in general and are low to highly-motivated in other areas considered. These results may be associated to the absence of teacher and student interaction. Using the relational and structural scoring of concept maps, it was found that the concept map scores of the learners before and after the use of AVL with OLS were found to be significant. This implies that the misconception of the learners has significantly improved. With this, the AVL with OLS can be utilized as a learning supplement to teach cell division with recorded moderate levels of motivation among learners as well as the significant improvement in the misconceptions among them. Nonetheless, more improvements may be applied to boost the motivation levels among learners.
