Using Edpuzzle as Learning Intervention Material in Addressing the Least Learned Competencies in Earth and Life Science
No full textAddressing learners\u27 least learned competencies through intervention programs is crucial because it requires strategic lesson planning and authentic assessments to achieve the desired learning outcomes. Currently, there are no attempts to use video lessons as learning intervention material to address the least learned competencies in Earth and Life Science. Thus, this action research explores using Edpuzzle as an innovative learning intervention material to address the least learned Earth and Life Science competencies among Aplaya National High School students. Focusing on the challenges in achieving mastery of metamorphism, the study identified the learning gaps using item analysis and mean percentage scores (MPS). The intervention was conducted among 30 Grade 11 students divided into two groups: one using the Edpuzzle video-based lessons and the traditional remediation. The post-test measured their level of mastery for both groups, while a questionnaire captured their level of perception. Results revealed that the Edpuzzle group significantly performed better than the traditional group, with an MPS of 73.33 compared to 42.67. Students who utilized the Edpuzzle found the online platform to be engaging, effective, and suited to their needs, with a mean perception of 3.41 (Strongly Agree). Statistical tests showed a significant difference between the groups, which suggests that the higher average scores of the Edpuzzle group indicate its potential to boost engagement and mastery. The findings will serve as a guide in developing intervention materials that can address the least learned competencies and foster the diverse needs of the learners across different learning modalities
Analyzing the Influence of Language Use on Sentiment Analyzers Using Reviews Gathered From Internet Platforms
No full textIn the Philippines, where Filipino-English code-switching thrives in online reviews, sentiment analysis struggles to capture nuanced customer feedback on platforms like Shopee and Google Maps. This study examines how code-switching and code-mixing affect six sentiment analysis tools—VADER, a Filipino Sentiment Analyzer (FSA), and four large language models (ChatGPT-4o, DeepSeek-R1, Gemini 2.0 Flash, Perplexity Auto)—and compares sentence-level versus review-level performance. Using a Shopee Philippines and Google Maps review dataset compiled by Cosme and De Leon (2024), 1,000 reviews were sampled in two stages, where 2,500 were first randomly selected, and from this, 1,000 were chosen to balance the sentiment distribution. These reviews were split into 2,589 sentences and annotated for sentiment (positive, negative, neutral, or mixed) and linguistic attributes (English, Filipino, or both; monolingual or multilingual; and code-switching or code-mixing). Model performance was evaluated using macro-averaged F1-scores, with accuracy also considered. Results show that code-switching and code-mixing degrade performance, with F1-scores dropping by 35% for VADER, 8% for FSA, and 9% for LLMs across review and sentence levels. VADER’s English bias limits its efficacy, averaging around 0.30 F1. FSA offers good resilience but performs modestly with a score of 0.40. LLMs were the most robust, maintaining scores around 0.82. Sentence-level analysis outperformed review-level, aided by localized cues. Positive and negative sentiments were classified accurately, while neutral and mixed sentiments remained challenging. These findings highlight the need for tools tailored to multilingual low-resource settings, guiding improvements in sentiment analysis for global e-commerce
Spatiotemporal Analysis of Spodoptera frugiperda (Fall Armyworms) Risk Using Known Growth Indicators in Select Municipalities of Tarlac, Philippines
No full textIn recent years, Fall Armyworm (FAW) reports have steadily increased in warmer regions of various continents, causing significant losses in the agricultural sector, especially in staple crops such as rice, corn, and sorghum. The pest species travels across warmer areas by riding wind currents and targeting crops. To combat FAW, farmers have developed and improved pesticide formulas and other control strategies, as the pest has shown resistance to many commercial pesticides used. However, FAW monitoring remains a challenge for the agricultural sector. With the agricultural nature of the Philippines, it is crucial to monitor the pest\u27s spread behavior in order to be equipped with proper mitigation measures. Thus, this study aims to develop an accurate FAW risk map that can detect and visualize FAW infestations in specific areas in Tarlac by utilizing known FAW growth factors as parameters, namely temperature, type of loam soil, and crop presence and integrating them using the QGIS software. It was found that during the wet seasons, the risk of FAW infestation levels is moderate to zero risk. On the other hand, risk levels increased from moderate to high during the dry season. Since soil and temperature conditions influence the risk levels of different areas in Tarlac, it is important to have varying approaches that fit the different needs of the area rather than a uniform solution
A Systematic Literature Review on Alternative Biodegradable Materials for Wound Dressing
No full textWound dressings have evolved from simple protective covers to advanced materials that actively promote healing while incorporating ideal properties for successful wound care. As research expands globally, efforts continue to develop ideal, cost-effective, and biodegradable dressings suited to various wound types. This study aims to identify biodegradable materials used in wound dressings, assess their physical and biological properties influencing healing, and examine their environmental impact and sustainability. Through a systematic literature review, data from multiple sources were consolidated for better efficiency and understanding. Results showed that commonly used materials like chitosan, alginate, cellulose, pullulan, and honey are effective and sustainable, offering antimicrobial effects, moisture retention, and support for cell regeneration. Some advanced dressings also feature smart capabilities. Despite this, there remains a lack of comprehensive environmental impact data, highlighting a need for further research to ensure wound care solutions are both clinically effective and environmentally friendly
Paper from Food Waste: Replacing protective packaging in Online shopping with Allium sativum (Garlic) Peels
No full textThe environmental impact of plastic packaging is a growing global concern, with the rise of online shopping and its dependence on single-use plastics like bubble wrap. This study explores the potential of Allium sativum (garlic) peels, an agricultural byproduct, as a sustainable alternative to protective packaging. Specifically, this study tests the effectiveness of garlic peels as a protective paper packaging in terms of durability and biodegradability, compares it to commercial protective packaging, and assesses its acceptability among local businesses. This paper found that It is more environmentally friendly and with improvements in its durability, the market acceptance will enhance. It is recommended for future researchers to collaborate with a paper manufacturer, explore using reinforcing agents, explore pre-treatment methods, improve the product\u27s marketability, perform a detailed cost analysis and to compare garlic peel paper to standard commercial paper instead of plastic bubble wrap
Chlorella vulgaris-Amended Cocopeat Compost: Soil pH and Soil Compaction Analyses
No full textSoil degradation in the Philippines, characterized by compaction, erosion, and salinization, significantly threatens agricultural productivity. This study investigated the potential of Chlorella vulgaris-amended cocopeat compost to improve soil health compared to conventional cocopeat compost. A posttest-only control group design was employed, testing two composts (with and without Chlorella vulgaris) in twelve containers with a 60:40 compost-to-soil ratio. Soil pH and compaction were measured using a calibrated pH meter and pocket penetrometer. Results showed that Chlorella vulgaris-amended cocopeat compost exhibited a slightly higher pH (6.53) than cocopeat compost (6.43), suggesting better pH stability. However, this difference was not statistically significant. Significantly lower compaction values were observed in the Chlorella vulgaris-amended cocopeat (0.20) compared to the control (0.328), indicating improved soil structure. While Chlorella vulgaris did not significantly affect soil pH in this study, the results suggest its potential as an effective amendment for soil compaction. Future research should investigate its effectiveness in real farm settings using larger-scale penetrometers and consider additional environmental factors to assess its overall potential as a sustainable soil amendment
STAROW: Development of Taro (Colocasia Esculenta) Leaves and Starch as Bioplastic Straw
No full textThis study aimed to develop a bioplastic straw utilizing taro (Colocasia esculenta) leaves and starch as a sustainable alternative to plastic straws. The researcher evaluated nine different set-ups, wherein three taro leaves to starch ratios (1:1, 1:2, and 1:3) were combined with three different drying temperatures (90°C, 100°C, and 150°C) to find an optimal composition. The results indicated the optimal composition straw was the 1:2 ratio dried at 100°C with the highest average flexibility, durability, and overall quality. In acceptability testing using a Likert scale among three qualified scientists, the ecological sustainability and practicality of the STAROW straw were ratified, although improvements on reusability were suggested. These results indicate that taro leaves and starch can indeed provide a sustainable replacement for single-use plastic drinking straws in support of the global initiative to reduce plastic waste and promote environmental sustainability
