Abstract:Science, Technology, and Society is one of the new General Education courses offered under the Philippine educational reforms implementing the Enhanced Basic Education Act of 2013 (Republic Act 10533). The teaching of STS presents significant challenges in ensuring that the students acquire the necessary competencies they ought to learn. Instructional materials in STS are only slightly adequate and slightly available. The study aimed to create a worktext that could serve as a valuable resource for educating students about the course. This study's research and developmental method involved creating and evaluating the worktext. The study used the 5E model of instructional design to develop the worktext. It was evaluated for its validity in terms of content, clarity, appeal to the target user, and originality. The evaluation revealed that it is highly valid and readable by the intended target users. It is recommended that the STS worktext be used in the course's teaching-learning process and should undergo an evaluation to further validate its effectiveness and practicability. Teachers should be trained and encouraged to develop their instructional materials related to their field of specialization with the support of the university administration

Abstract:Blood chemistry testing requires centrifugation as one of the crucial pre-analytical phases. Usual differences in the speed and time of centrifugation influence specimens to varying extents among laboratories. This prompted the researchers to ascertain the effects of varying centrifugation speeds and times on healthy individuals' blood chemistry values and reduce the centrifugation time attested by the World Health Organization (WHO). Blood specimens were collected from four healthy adults, centrifuged, and then analyzed using the VITROS 5600 Automated Machine. The drychemistry principle was applied. Three sets of speed and time were applied (1) 3,500 RPM for 15 minutes (WHO recommended), (2) 3,750RPM for 10 minutes, and (3) 4,000 RPM for 5 minutes. The parameters include Fasting Blood Sugar (FBS), Total Cholesterol (Total CHOLE), Creatinine (Crea), Sodium (Na), and Potassium (K). The results of the serum chemistry values have no significant difference between different speeds and times against the standard set by WHO and were found to be acceptable, normal, and close in range with each other. Therefore, these can be substituted forthe WHO-recommended speed and time. The researchers forward the following recommendations: (1) tests should be conducted to respondents with comorbidities and to younger and older individuals; (2) conduct the tests in triplicates and consider using other methods and more participants should be considered; and; (3) consider lesser time in centrifugation.
