    The use of instructional videos as a learning tool and students' self-concept in learning mathematics
    Tan, Crystal Jane N. (Davao del Sur State College, 2024-02)
    The study of mathematics is unique and essential to education. People use mathematics on a daily basis in various fields and aspects of life. Basically, utilizing technological advancement in educating students in Mathematics is a challenging assigned responsibility that involves taking into contemplation several types of aspects, such as teaching methods, subject matter, and student engagement. Additionally, a student's self-concept in mathematics can be assessed by how confident they are in their ability to grasp new mathematical concepts and perform well in class. This is how students perceive their mathematical skills and knowledge. To identify the relevant relationship between the use of instructional videos as a learning tool and students' self-concept in learning mathematics. This quantitative study was organized by utilized detailed-correlational survey method to gathered information using an modified questionnaire from Adlawon et al., (2022) and Bunag (2015). The information of the research was collected by employing a questionnaire consisting of two parts. Part I, is requested to ascertain the use of instructional videos as a learning tool in terms of its: Purpose, Content, and Video Quality. Part II, is to determine the students' self concept towards mathematics in terms of: Learned, Organized, and Dynamic. At Davao del Sur State College at Matti, Digos City is where this research study was carried out. After the researcher obtaining the list of BSED-Mathematics students from ITED, 141 respondents were anticipated between the use of instructional videos as a learning tool and students' self-concept in learning mathematics.

    Cost-efficacy of seaweed-based liquid biostimulant as pre-treatment prior to outplanting of Kappaphycus alvarezii
    Marquez, Kathleen Jane Z. (Davao del Sur State College, 2024-05)
    This experimental study determined the cost-efficacy of using seaweed-based liquid biostimulant (SLB) as a pre-treatment prior to outplanting Kappaphycus alvarazii and it was conducted at Sitio Biao, Barangay Cogon, Digos City, Province of Davao del Sur, Philippines. Five different levels of treatments were used; control farmers practices (T1), 9g of Urea Inorganic Fertilizer (T2), 10 ml seaweed-based liquid biostimulant (T3), 20 ml seaweed-based liquid biostimulant (T4), and 30 ml seaweed-based liquid biostimulant (T5). Four replications were done in each treatment and all were places randomly in farming site. The yield and specific growth rate (SGR) were recorded and the cost-efficacy of each treatment was analyzed. After 30 days of cultivation, a significant increase in the yield and growth rate were observed in all the treatments. Result also shows that as SLB increases its dosage, the yield and SGR of the Kappaphycus alvarezii after 30 days also increases. The cost-benefit ratios (CBR) of the five treatments in this study was also calculated. T3, T4 and T5 stood out as both portrayed a positive return on investment, at 1.01, 1.27 and 1.42 respectively.
