Poetry reading strategies and comprehension skills of grade 9 SPA students
Camat, Lovely Mae M. (Davao del Sur State College, 2024-05)
The research was intended to determine the relationship between poetry reading strategies and comprehension skills among the grade 9 SPA students at Digos City National High School. An instrument that was modified was used to collect data from 122 respondents using a correlational approach. The findings showed that students use a very high degree of reading methods in terms of engagement in the poetry discussions and proficiency in reading comprehension. Meanwhile, the analysis skills in poetry comprehension, understanding, and interpreting poetic language were at a high level. However, no significant relationships were found with other strategies and skills.
Learning outcomes of mother tongue subject and English language competencies of grade 3 pupils
Eben, Jel Rose V. (Davao del Sur State College, 2024-01)
The implementation of the Mother Tongue education had gained numerous implications, one of its reason is the impact of Mother Tongue to the English speaking competencies of the students, which are highly believed that it is an essential to succeed academically and anything that calls for English language abilities. Herewith, this quantitative study, which took a descriptive correlational approach, obtained an in-depth understanding about the student's capacity in regards to their level of English-speaking competencies. This study was conducted last June (2023), involving 91 grade 3 pupils who willingly gave their time to participate in this study. The data were gathered using in-depth interviews with the use of ACTFL oral proficiency interview that ought to test the English-speaking competencies of the grade 3 pupils. The data were analyzed to assure that the results are reliable. The outcome of this study concluded that the grade 3 pupils has an outstanding performance in regards to their learning outcomes in the Mother Tongue subject. This study also proved that the level of English speaking competencies of the pupils was distinguished which also concludes that their learning outcome has a significant relationship to their English-speaking competencies.
Students' capability, attitudes and performance in research: Basis for capacity-enhancement program
Dayon, Elmer A. (Davao del Sur State College, 2025-05)
This study aimed to assess the research capabilities, attitudes, and performance of students in public secondary senior high schools within the Division of Davao del Sur. Specifically, it explored the relationship between students' research knowledge and skills, as well as their attitudes toward research, which included dimensions such as anxiety, perceived usefulness for professional growth, relevance to life, perceived difficulties, and overall positivity. Employing a descriptive-correlational research design, data were gathered using survey questionnaires administered to a sample of students. The data were analyzed using statistical tools such as weighted mean, Pearson product-moment correlation, and multiple regression analysis. Findings revealed that neither research capabilities nor students' attitudes had a statistically significant influence on their research performance. This indicates that, despite possessing adequate knowledge and maintaining generally positive attitudes, students may still underperform in research activities. The results suggest that internal factors alone are insufficient to predict or influence research performance. Therefore, further investigation into external or unexamined variables is warranted. In particular, the school's research culture, students' language proficiency, and access to research-related resources may play crucial roles in shaping students' research experiences and outcomes. A lack of a supportive environment, limited English proficiency, and inadequate access to relevant materials or technology could hinder students from effectively applying their skills or maintaining motivation. Addressing these contextual factors may provide deeper insights into enhancing student engagement and performance in research. Future studies and intervention programs should take these external influences into account to create more holistic and effective strategies for improving research education.
Mangrove community structure, aboveground biomass, and carbon stock assessment in the coastal area of Santa Cruz, Davao del Sur, Philippines
Sante, Gle Liezl C. (Davao del Sur State College, 2025-05)
Mangrove ecosystems play a crucial role in carbon sequestration and climate change mitigation. However, these functions remain understudied in Sta. Cruz, Davao del Sur. Thus, this study assessed the mangrove community structure, aboveground biomass, and carbon stock in the area. Thirty-six 10 x 10 m transect plots were established for tree inventory and measurement. The mangrove forest consists of five species from three families, exhibiting low species diversity (H'=0.83) and significant species dominance (D=0.53), yet high evenness (J'=0.70). Among sites, Tuban had the highest diversity (H'=1.04), and evenness (J=0.94), with no dominant species (D=0.37). Avicennia marina was the most abundant species (RA=67.80%) and had the highest importance value (IVI= 114.77%). Despite its limited population, Sonneratia alba contributed the most to aboveground biomass (x= 110.11 Mg ha-1) and carbon stock (x=52.85 MgC ha-1). A weak negative correlation (rs= -0.1) was observed between species importance, aboveground biomass, and carbon stock. The mangrove forest's average aboveground biomass (43.87 Mg ha-1) aligned with IPCC default values, while its carbon stock (21.06 MgC ha-1) was comparatively lower. These baseline data suggest that while the area retains considerable biomass, but less carbon stock and low biodiversity, underscoring the need for targeted conservation efforts to enhance the ecosystem's stability and ecological function.
Household utilities monitoring system using geofence technology with data analytics
Suizo, Clyde Andrie G. (Davao del Sur State College, 2024-06)
This study was conducted to determine that combining geofence technology into household monitoring systems was an approach to improving utility management and monitoring more efficiently and effectively. While the previously mentioned changes had already been integrated into systems used to monitor household utilities, it was clear that there was a lack of monitoring systems that utilized geofence technology. Such methods were more useful among locals in Don Lorenzo Homes Subdivision, Tres de Mayo, Digos City. As a solution, the monitoring system created in this study achieved the following functions; (1) used a motion sensor as the geofence to cover the entrances and exits of the household with an effective range of 250cm and an effective angle between 60 and 120 degrees, (2) used light and gas sensors integrated into household utilities to gather real-time information with an effective range of 60cm and 20cm respectively, (3) visualized data with the help of bar and line graphs using graphical analytics techniques to display the collected data. Through pilot testing and evaluation, the system gained a 4.2 weighted mean with a remark of GOOD, which demonstrated that employing geofencing techniques increases the efficiency of the homeowner's household utility management. The capstone project stood to make significant contributions to the research field by combining geofence technology and sensors to enhance household utility management. The anticipated benefits in terms of energy efficiency, cost savings, and household utilities management highlighted the project's potential to influence both academic research and practical applications in the smart home domain. The research outcomes could serve as a foundation for further studies, leading to the development of more sophisticated systems and inspiring new approaches to energy efficiency, sustainability, and management.
