| 2291 | 2024 Article | Incorporation of graphene oxide/metal Oxide into modified polyvinylidene fluoride membrane for the degradation of methylene blue dye through adsorption-photocatalytic activity Siti Nor Aisyah Jamilon Recent studies have demonstrated substantial advancements in the treatment of dye wastewater through the synergistic incorporation of graphene oxide (GO) and metal oxide. This research focuses on the successful fabrication of a GO-based composite membrane using the non-solvent induced phase separation (NIPS) method. Two distinct metal oxides, titanium dioxide (TiO2) and zinc oxide (ZnO), were incorporated into polyvinylidene fluoride (PVDF) as the membrane carrier. The resulting membranes, namely PVDF/TiO2, PVDF/ZnO, and PVDF/TiO2/GO, were developed as photocatalyst membranes for the treatment of methylene blue (MB) dye contamination through adsorption-photocatalytic activity. The adsorption process was conducted for 30 minutes before initiating the photocatalytic activity. Upon UV-Vis measurement, the PVDF/TiO2/GO composite membrane exhibited superior dye degradation efficiency, reaching 91.89%, as compared to PVDF/TiO2 (91.38%) and PVDF/ZnO membrane (86.80%). This noteworthy enhancem..... 183 hits |
| 2292 | 2024 Article | Exploring the magnetic field strength of a solenoid using the magnetometer of a smartphone Pacala, Frank Angelo This paper investigated the magnetic field strength of a solenoid using the magnetometer of a smartphone. There were three experiments: magnetic field strength versus current; magnetic field strength versus number of turns; and magnetic field strength vs distance between smartphone and solenoid. The result of the experiment has found that magnetic field strength and current and magnetic field strength and number of turns have direct relationship to one another and conformed with the Ampere’s Law. Meanwhile, the magnetic field strength vs distance between smartphone and solenoid has an exponential relationship. This paper recommended to verify the permittivity of free space by revising the experimental set-up. From educational uses to practical applications, it provides the teaching and learning process with a convenient tool for measuring magnetic field strength at various points with incredible precision and accuracy with minimal effort required.

| 2293 | 2024 Article | Evaluating eco-friendly soil neutralizers the use of pulverized eggshells and clam shells in enhancing rice field soil acidity Vasquez, Franz Yanzy C. Soil acidity is an important factor in the yield of rice crops. This article aims to determine the effectiveness of alternative soil neutralizers in agricultural land in the form of utilizing the calcium carbonate and calcium oxide content of pulverized eggshells and clam shells. This study used an independent T-test to determine the difference between the alternative soil neutralizer and commercially- made soil. A total of 45 samples were gathered: these are, along the side of the road, along the irrigation, and away from the road and irrigation. These sites are divided into 4 corners, 1 at the center, and then by 3 based on the depth of the soil sample, separated by 6 inches from top, middle, and bottom. The soil samples were mixed with these neutralizers with a 1:1:2 ratio and recorded a day, three days, and seven days. When mixed with the alternative neutralizers, the results showed a mean of 7.71 pH after seven days while the commercial neutralizers showed a mean of 7.84 pH. The r..... 398 hits |
| 2294 | 2024 Article | Development and content validation of modular textbook on mathematics in the modern world at Sorsogon State University, Sorsogon, Philippines Calaminos, Franklin P. Modular textbooks are widely recognized as a valuable resource for teaching mathematics in schools and colleges. This descriptive-developmental research aimed to provide a research-based modular textbooks for course Mathematics in the Modern World. Difficulties encountered in mathematics by 100 Grade 11 students from three public secondary schools in Magallanes, Sorsogon were identified along with the prescribed topics and competencies by CHEd as inputs on the development of the textbook. As a result, the developed textbook is consisting of 21 modules since 7 units of 3 lessons and each module is divided into 10 parts. Modules related to proofs, logic and functions as the top 3 difficult key concepts were given more emphasis in terms of examples and activities to be included. Five experts who are teachers that have experienced teaching MMW have evaluated the textbook in terms of design, format, and OBE alignment. It was found out that the textbook is very satisfactory with a weighted m..... 287 hits |

| 2296 | 2012 Thesis | Short term in-service courses for secondary school music teachers in the state of Malaka Ling Chin Ngor Short-term in-service courses are required by the Ministry of Education Malaysia (MOE) to provide professional development for teachers. Most of the courses organized by the MOE have been conducted by the Teacher Professional Development Sector. All government teachers in Malaysia, including secondary music teachers, are required to complete seven days of professional development each year. The focus of the study is to determine whether the courses organized meet the needs of secondary school music teachers. The study investigates the types of short-term in-service courses completed and required by secondary school music teachers in the state of Melaka. Twenty-four music teachers from the state of Melaka were selected and sent a survey. The survey identified the courses completed and the musical, pedagogical, and technical knowledge acquired through the courses. The data were analyzed using SPSS software with descriptive analysis.

| 2299 | 2023 Thesis | Gender differences and the effects of Think-Pair-Share strategy on speaking performance of ESL students Guganeswary Vellayan Excellent speaking skill is crucial to endure in a highly competitive world. If English as
Second Language (ESL) students have a good command of English language proficiency,
a better future awaits them locally and internationally. Thus, this study investigated the
gender differences and the effects of the Think-Pair-Share (TPS) strategy on the speaking
performance of Malaysian Chinese ESL students. A mixed-method research design was
used to study the Form Four ESL students at a Chinese Independent High School (CIHS).
Forty ESL students, comprised of 20 male and 20 female students, participated in this
study. A pretest and posttest were conducted on the control and experimental groups before
and after implementing the think-pair-share strategy in the English Communication
