Plastic pollution has become a global concern, and the country Philippines is one of the plastic waste generators worldwide. The accumulation of non-recyclable, single-use plastics threatens marine life and contributes to global warming. This study aimed to contribute to reducing plastic pollution and provide insights into sustainable alternatives to single-use plastics. Hence, this research explores the potential of bioplastics as an alternative to traditional plastics. Specifically, this study primarily focused on developing bioplastics using taro and sea grapes as raw materials to provide an eco-friendly alternative to traditional plastics. The researcher aimed to investigate three different concentrations of bioplastic made from taro and sea grapes and evaluate their tensile strength, water absorbency, and biodegradability. The findings revealed that the second sample, consisting of 20 grams of taro starch, 15 mL of sea grape extract, two tablespoons of vinegar, 7.5 mL of glycerine.....

The complexity of Probability and Statistics Education was intensified by several concerns in the education sector brought by COVID-19 contagion. This study examined the Philippine Kto10 Most Essential Learning Competencies (MELCs) in Probability and Statistics by comparing the content topics and learning competencies with the Kto10 Mathematics Curriculum. This Critical-Qualitative approach of study used curriculum mapping as a method of analysis in the identification of the gaps in the MELCs across the grade level along with lesson continuity and lesson congestion backed up with the experiences and responses of 12-Math teachers (5 Elementary,7 Secondary) who were informants of the study. This investigation found out that the learning competencies in Probability and Statistics of the Kto10 Mathematics Curriculum were reduced (from 89 to 66 learning competencies) across grade level to cope up with the present educational crisis brought by the pandemic. The issuance of Most Essential Lea.....

Despite the significant dangers that countries suffer when adolescent pregnancy is neglected, this major problem usually receives little attention. In recent decades, the number of teenage girls who get pregnant has increased worldwide. Therefore, this issue has become many countries' main public health concern. This paper aims to use MATLAB to estimate Malaysian teen pregnancy data for the next few years and to find missing data for a particular year. Since the Runge-Kutta is used to forecast the prevalence of adolescent pregnancy in Malaysia, the comparison reveals that the two sets of data are distinct. Therefore, the order four Runge-Kutta method is insufficient to approximate incomplete data for adolescent pregnancy. Although the results show that adolescent pregnancy has decreased over time, we must continue to treat this issue seriously. It is necessary to educate teenagers about sex education and safe pregnancy. Educating the young about the risk of having pregnancies in their .....

This study examines the impact of self-regulated learning materials on the academic performance of Grade-3 students. Pre-test and posttest were implemented to identify the development of self-regulated learning materials. The materials underwent a validation process by the expert to ensure their content, format, presentation and organization, accuracy, and up-to-datedness were appropriate. Validating self-regulated learning materials is crucial to ensure suitability and efficacy. Furthermore, the materials evaluated based on phase, including forethought, volition, and self-reflection. Selfregulated Materials was evaluated by the school head for validation. A validated material has been carefully reviewed by experts to ensure that it is appropriate and effective. The evaluation rated as very satisfactory. The results indicated that these materials greatly extent students' ability to regulate their learning, enhance motivation, and develop critical think skills. The Pre-test and post-tes.....

Prior knowledge is crucial in acquiring new mathematical concepts, yet students frequently forget what they have learnt, which hampers their acquisition of new mathematical concepts. It has been observed that poor mastery of algebraic conceptual and procedural knowledge leads to poor knowledge retention, which in turn impairs learning in other areas of mathematics. Rote learning was assumed to be the definite way to grasp algebraic conceptual and procedural knowledge, but it has now been demonstrated that such knowledge rots when not used. This paper describes the development and validation of the ConProRet-A module for use in mastery and retention of algebraic conceptual and procedural knowledge for Form 1 students. Hence, the ASSURE model, APOS theory, Scaffolding theory, and Atkinson and Shriffin information processing theory were involved in the development of the mentioned module. To obtain the face validity percentage and content validity percentage for the module, five experts w.....

Due to remote learning, chemistry laboratory experiments have been difficult to implement. With this, the study explored the design of experiments on chemical kinetics that can be conducted at home. Seven STEM high school teachers participated in the study and underwent the process of designing the aforementioned experiments. Their experiences showed that they consider material availability in formulating the at-home activities. The design of their experiments underwent several processes: (1) making the flowchart, (2) conducting the pilot test, (3) illustrating the interactions in the particulate level, (4) writing corresponding chemical equations, (5) answering the experiment goal, and (6) finalizing the lab worksheet. In conclusion, high school teachers can design experiments on chemical kinetics and be trained for the macro-micro-symbolic understanding of chemical phenomena and the thorough design process ensures the possibility of implementing these home-based experiments to the st.....

The Simple Harmonic Oscillation (SHO) is a fundamental concept in physics, as it describes a large variety of phenomena that occur in nature, such as the motion of pendulums, mass-spring systems, and atoms. A thorough understanding of SHO can provide a good foundation for learning more advanced topics in physics, making it an essential topic for students to learn. Computer simulation technology provides an effective way to model SHO phenomena in the classroom. This technology allows students to explore SHO concepts visually and to replicate experiments that would be cumbersome or impossible to conduct otherwise. However, there are few compilations of SHO simulations appropriate for classroom use. This paper presented a compilation of SHO experiments that utilize computer simulation of PhET. The compiled experiments cover a broad range of SHO concepts, including proving the relationship of energy and amplitude, velocity and displacement, acceleration and displacement and types of dampin.....

In this study, we offer a low-cost laboratory practice for an introductory physics class laboratory for students of any grade level in science and engineering. This practice, in which a mobile phone (iOS, Android, or Windows) is used in conjunction with mini magnets (similar to what's found on refrigerator doors), a rule, paper, and a free application (app) which has to be downloaded and installed to measure magnetic fields by using smartphone's magnetic field sensor or magnetometer, was very well received by our pupils. This practice is completely free. The major aim of the exercise is for students to discover the influence of component x of the magnetic field produced by various magnets. We discover that the magnetic field's dependence on distance takes the form _____, which is perfectly compatible with the theoretical analysis. The second purpose is to compute the magnetic field found in various types of household electronic devices. Keywords: Measurement of magnetic field u (MaFiU).....

The study aimed to determine the preferred programming language among information technology professionals using non-negative matrix factorization topic modelling technique. The results showed that the majority of participants were software developers and programmers who commonly used C#, Java, and Python, and agreed that Java, C, or C++ would be the best language to start with when learning programming. The application of topic modelling revealed key themes such as online video tutorials as effective learning resources, hands-on activities as key to learning programming, importance of feedback, effective teaching strategies, and problem-solving skills as crucial for success in programming. Results of the study may serve as baseline data for the improvement of curricular offerings. Keywords Topic Modelling, NMF, T, Industry, Programming..
