The physical parameters of the lake showed no difference and the chemical analysis indicated that pH, carbonate, sulphate, and fluoride concentration were higher in the anthropogenic part of the lake. This shows that human/animal interference and thermal spring water play a role. Of the three transactional areas of the lake, samples from the flooded area of the lake showed the highest alkalinity and bicarbonate concentration, while samples from the protected area showed the lowest alkalinity. The mercury and arsenic contamination was highest in the protected and anthropogenic parts of the lake respectively.

The root cause of this issue is the decline in students’ interest in learning mathematics alongside their insufficient critical thinking skills. This has posed challenges among mathematics teachers to innovate ways on how to enhance students’ critical thinking skills and motivate students towards better performance in mathematics. The primary objective of the study was to determine the effectiveness of a contextualized question-embedded video-based teaching and learning tool on the interest and mathematical critical thinking skills of Grade 10 students. The study used a descriptive experimental research design with the REACT and Socratic methods to contextualize and embed questions in the video tool. A survey questionnaire was used to assess students’ interest before and after utilization, and a pretest and posttest assessment was conducted to evaluate students’ interpretation, analysis, evaluation, and inference skills. Based on the findings, using a contextualized question-embedded video-based teaching and learning tool is effective in increasing students’ interest and critical thinking skills. Moreover, there was a significant difference between students’ mathematical interest in terms of their attitude, initiatives, mathematics experience, and the utilization of contextualized question-embedded video-based teaching and learning tool. The pretest and posttest results of the experimental and control groups also showed significant differences in critical thinking skills. The study concludes that using contextualized question-embedded video-based as teaching and learning tools effectively improves students’ interest and critical thinking skills in Mathematics. Further larger-scale studies with different grade levels can validate the findings of the current study.","PeriodicalId":326677,"journal":{"name":"International Journal of Science, Technology, Engineering and Mathematics","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124735158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fabrication of the device was based on the needs of roof painters to lessen their exposure to sunlight during roof painting. The roof paint sprayer was divided into three major parts. First, the container served as overall part with hand carry at the top, which weighs 6 kilograms when empty but approximately 11 kilograms when full. Second, the direct current motor is rated 60 W, 12 V nominal, maximum flow of 5 liters per minute, and a maximum pressure of 116 psi. The base of the motor was fitted at the bottom while the hole of the first container is connected to the inflow of the motor, and a hose with an adjustable nozzle is connected to the outflow. Third, the power source consisted of a connector cord, female socket, 12V transformer, circuit board, green LED, 12Vdc battery, battery indicator, and switch. The performance evaluation of the device revealed during testing showed that at the start the roof paint sprayer works smoothly and sprayed almost 1/3 area of the target area (10×3 meters) for almost 2 minutes but suddenly as it sprayed, the dc motor starts difficult to run until it stopped. The major benefit of the device, if studied further, will spray faster on roofs and smooth output.","PeriodicalId":326677,"journal":{"name":"International Journal of Science, Technology, Engineering and Mathematics","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134123230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the AQUAMAG device and web-based platform, the water quality is assessed in real time, and the current water status is monitored. There is a webpage for viewing all the recorded data from the database for analytical monitoring purposes. At the same time, the device sends a message notification to the user for the water condition update. The evaluation-based ISO 25010 standards showed end-users remarkably accepted the device attributed to the accurate turbidity and pH sensors. This water monitoring mechanism can help the user visualize if the water source is polluted or contaminated through a water quality test. With its efficient application and practicality, it has excellent potential for the community. Hence, a portable and user-friendly device that can be used within households and establishments as an alternative way of checking water quality before using it can be developed. Relatively, the study can raise awareness on water quality in the community through the developed device, which can also avoid illnesses caused by contaminated water.","PeriodicalId":326677,"journal":{"name":"International Journal of Science, Technology, Engineering and Mathematics","volume":"64 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133508844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study used experimental research design by measuring the improvement on the performance of the students after the implementation of the researcher-made PBL material. It also used survey strategy to assess the acceptance of the students on the quality of the developed PBL material and correlated the results with the critical thinking skills before and after the use of the material using paper and pen test. Results revealed that learning experiences relate to inferring, communicating, and problem-solving. There is also significant relationship between learning outcomes and communicating and problem solving. Both effectiveness and efficiency and user-friendliness significantly relate to communicating learning experience while congruence relates significantly to all critical thinking skills. Thus, learners’ use of the PBL material increases their critical thinking skills as evidenced by the t–test results showing significantly different critical thinking skills before and after the use of PBL material. With the improved level of students’ critical thinking skills, the PBL material may be used as a supplementary in the delivery of the lessons in any subject area.","PeriodicalId":326677,"journal":{"name":"International Journal of Science, Technology, Engineering and Mathematics","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124633200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In line with this, the study sought to determine the efficacy of using infographics in enhancing the scientific knowledge of 160 grade 8 students in Alaminos Laguna. Furthermore, it investigates the students’ dual coding cognition as inputs to developing the infographic materials. It also evaluates students’ preferences for static and animated infographics, and evaluators’ ratings of the created infographics. This study is descriptive developmental in nature, as it employs survey questionnaires to assess students’ dual coding cognition, students’ preference for static versus animated infographics, and experts’ ratings on the designed infographic materials. It also creates, designs, and assesses infographic learning materials in accordance with the criteria established to be effective. The results showed that students’ dual coding cognition in terms of verbal and imagery is both “practiced” and that both infographics were “preferred” by the students. The static infographics received an “excellent” score from the expert raters, while animated infographics received a “very good” rating. The result generated showed infographics enhanced learners’ performance and demonstrated a substantial difference between their pre-and post-test scores in terms of scientific knowledge.
