This study aimed to develop and validate a multimedia-based instructional module in Science 7. This was initiated as a response to the poor performance of Filipino learners on international and national standard assessments in Science. A descriptive approach of research was utilized in developing and validating the module. Each lesson in the module consisted of the following parts: learning objectives, pretest, discussion of the topic, activities, posttest, and references. The development of the module underwent four phases: planning, content validation and analysis, designing, and development. The Lawshe’s content validity formula was used in determining the essential learning competencies that were included in the module. A validation tool was used by ten experts in validating the content, design/format, technical/technological, and pedagogical aspect of the module. Results of the study showed that all of the validators agreed that the developed multimedia-based instructional module in Science 7 met all the criteria found in each parameter on the validation tool. Therefore, it was concluded that the developed multimedia-based instructional module can be used as instructional material by Science 7 learners.

American superhero-themed films can represent good characteristics and they could be a good way of developing one’s characteristics. By utilizing American animation, superhero and fantasy films as the main data such as Fantastic 4 (2005), Fantastic 4: Rise of Silver Surfer (2007), Frozen (2013), Black Panther (2018), Frozen II (2019), and Aladdin (2019), this qualitative research focuses on the significance of character development and the representations of good characteristics depicted in the films which can be used as a tool for character education. The process of analysis involved the use of Stuart Hall’s representation theory. The results of study suggested that character is something that is essential to develop, especially in teenagers and it is not only about having a good attitude, but it also involves living a good life. In addition, this study showed that at least five good characteristics such as caring, tolerance, politeness, solidarity and kindness frequently appeared in the observed films which can be used as media for teaching about characters at schools or informal educational institutions.

This study investigated the effect of study habits counselling on the academic achievement of senior secondary school students achievement in English language in North-west, Benue State, Nigeria. The study adopted a Quasi-experimental design. The population of the study was five thousand, three hundred and twenty nine SS2 students (5,329) of public schools. The sample size for the study was 100 senior secondary school 2 students drawn from intact class of a public school through multi stage sampling technique. Two instruments were used for the collection of data, English Achievement Test (EAT) and Study Habits Counselling Questionnaire (SHCQ). The reliability of the research instruments was established using Lemma co-efficient Alpha. Data was collected and analyzed using mean and standard deviation to answer research questions and Analysis of Covariance (ANCOVA) to test the hypotheses. Findings revealed that study habits counselling has significant effect on the academic achievement of secondary school students in English. Study habits counselling has no statistical significant difference in the mean score of male and female students. The study concludes that study habits counselling has effect on the academic achievement of students in English, however, there is no significant difference between male and female. Thus, group guidance should be organized in schools to create awareness on effective study habits. A functional school library should be mounted. Parents and guardians should encourage their children to set up schedules for study. Qualified English teachers should be employed in all secondary schools. Guidance counsellors should include study habits counselling as part of new students’ orientation to facilitate effective study habits among new students.

A data center can be a single structure that contains computer systems or servers, as well as major elements including such storage and network communication systems, or a cluster of buildings that contain movable systems and related components (such as storage and telecommunications systems). All of the business area units’ key operations are run on portable servers in the data center. Several environmental and security hazards can be addressed, and continuous services can be supplied to users, thanks to the data center’s limitless observing conditions. Backup power, environmental management, and redundant data transfer connections are all included. The data center’s security and privacy are critical in this instance. It is critical to avoid time periods in the data centre. Furthermore, as public awareness of environmental issues grows, data center energy consumption has risen to the top of the safety management priority list. Failures in the temperature and humidity functions will be significant. It is critical to pay strict attention to the data center’s security at all times. Manual data center monitoring, on the other hand, is becoming increasingly time-consuming. Units in the technical field are currently emerging at a rapid pace. The data center is under the most strain in this instance. A good detector network, on the other hand, is critical to the advancement of Business 4.0 technology. As a result, we like to utilize a good network of detectors for data center observation protection and privacy. The Internet of Things is frequently utilized for data center observation, as well as a good wireless detector network. A wireless detector system is employed in this paper to track the effectiveness of adjustments in real time.

In time of pandemic, synchronous and asynchronous learning occurred as a form of distance learning implemented by the Commission on Higher Education and the Department of Education. This research entitled “Academic Dishonesty Cheating in Synchronous and Asynchronous Classes: A Proctored Examination Intervention” was conducted to identify the self-report and types of assessment stated by the respondents. It also determined the effectiveness of proctored synchronous and asynchronous examination in preventing the cheating practices of students. The researchers used a quantitative research design and three adapted questionnaires with 40 participants. The results generated from the questionnaires were analyzed using frequency, percentage, and Mann-Whitney U test. The results obtained the following: most students cheated on assignments, exams, or quizzes; the primary reasons for student dishonesty were stress and worry essentially, and homework was the kind of evaluation that enabled pupils to cheat. Proctored exams provide similar results regardless of whether the exams were conducted asynchronously or synchronously. The following findings on the impact of proctored synchronous and asynchronous exams on students revealed that: most students will be less likely to cheat in a proctored examination. Most of the students believed that these proctored examinations would be a good solution in monitoring remote learning. Therefore, proctored synchronous and asynchronous examinations prevent the academic dishonesty or cheating practices of students.

Forensic science is the application of science in order to serve the law. Among the vast field of forensics, forensic DNA casework is widely considered as one of the most outstanding types of forensic evidence. To better implement forensic investigation procedures, public awareness of forensic science is crucially required. The aim of this study is to evaluate the level of awareness among Lebanese public community by assessing their knowledge and perception regarding forensics and to question their willingness to participate in the national DNA database or in scientific research. A cross sectional study was conducted over 400 adult Lebanese from both genders residing in the five Lebanese governorates. The survey questionnaire was designed and carried out from August 2021 to February 2022 with 89% as responsive rate. The participants’ characteristics were under study as well as their knowledge and perception statements in the purpose of investigating their relative association through independent t-test. The study revealed that 40% of the participants were aware of the forensic science. In addition, only 26% of the participants are willing to provide DNA sample. Moreover, sex and marital status factors has no impact neither on their public awareness nor on their intention to donate a DNA sample. Nevertheless, characteristics such as age, education, profession, and residency has significant differences. The survey identified that younger, employed, more educated people, and individuals residing in cities showed a better awareness of forensic science and intention to provide a DNA sample. However, it is very early to decisively predict the level of awareness and the rates of participation given the fact that nationwide surveys have yet to be launched. By consequence, awareness campaigns to increase public awareness on the importance of forensics is necessary to reduce concerns and gaps in Lebanese personal knowledge, and to encourage their future participation.

Learning science is the most exciting part of being a high school student. The fun learning through exploration and laboratory experiments is the best part of science. This study aimed to test the effectiveness of the heuristic approach with the teacher-made worksheets as a teaching innovation in distance learning in helping the respondents to understand the topics of General Biology 2. This research employed a mixed-method; the qualitative data were evaluated using the phenomenological technique, while the quantitative data were processed using the Statistical Package for Social Sciences version 25 (SPSS v.25). The researcher used a pretest, five teacher-made worksheets, a posttest, and a delayed posttest as tools. Also, focus group discussion was considered to find out the common problems encountered by the students and the researcher himself. All the gathered data was recorded digitally and through field notes and discreetly handled. There are 10 enrolled students in Science, Technology, Engineering, and Mathematics (STEM) during the school year 2020–2021, and they were all chosen purposefully. This study involved the five-week topics in the second semester of the 3rd quarter. Results revealed an increase in the respondents’ learning performance based on the mean percentage scores of the posttest. Based on the increase in the mean of the delayed posttest, the innovation promotes retention for the students. The researcher and the students had technical problems because of a power outage and unstable internet connections. Still, respondents face the challenges of output management and helping their parents first before learning. There is a significant difference in the respondents’ performance before and after implementing the innovation. The heuristic approach to teaching improved the performance of the STEM students at San Felipe High School under the subject General Biology 2. It is recommended that teachers use the heuristic approach to teach students how to work in a digital world.

Misconception sabotages the meaningful learning. Young learners can have misconceptions about the science concepts with which they interpret their new experiences, hampering the development of canonical scientific knowledge. Identifying and remediating the misconceptions of the learners is an important task as an educator. Therefore, this study aimed to explore the misconceptions of the 9th grade students on particulate nature of matter (PNM) concept and effectiveness of the use of video animations in remediating those misconceptions. The study adopted a mixed method approach. The sample consisted of 20 students studying in 9th grade of Daga Central School in Bhutan. The misconception was identified using the certainty of response index (CRI) diagnostic technique. The study revealed 10 kinds of misconceptions held by students related to PNM, under the four themes, i.e., All matter is made of discrete particles, Space between the particles is empty, Particles are in constant random motion, and Bonds or forces exist between particles, the number of students’ having misconception on the particulate nature of matter concept reduced considerably in the post-test after the use of video animations as the intervention. The study also revealed that most of the misconceptions that student possesses were rooted in their inability to understand the chemical concepts from macroscopic, sub microscopic, and symbolic perspective. The study contributed in two aspects: first, the study identified four themes in which students had misconceptions, alerting educators to be cognizant when involving in discourse of PNM concepts. Second, the study suggests that use of video animations as a potent strategy to teach PNM concepts to help students develop the canonical scientific knowledge on PNM concepts, as demonstrated by this study.

Higher Education Institutions (HEIs) in the Philippines are focusing on graduates employability. The immediate supervisors’ demand is very high as they look for graduates who are flexible, willingness to learn the job, technically competent, and committed to excellence. Thus, this study was conducted to determine immediate supervisors’ satisfaction on teaching competence of teachers produced by one State College in Western Visayas. The descriptive-quantitative research design with a standardized research instruments was employed. Since there were a total of 48 graduates in the year 2002-2019 the researcher decided to take them all as respondents. Frequency count, percentage, and mean were used in the descriptive statistical test and Mann-Whitney and Kruskall Wallis analysis for differences in the immediate supervisors’ satisfaction and teachers teaching competence level. Results revealed that respondents’ instructional skills, personal and social qualities were rated as “Surpasses Expectations” and “Very Satisfactory” in teaching competence. Moreover, it was found out there is no significant difference in the immediate supervisors’ satisfaction and on the teaching competence of teachers as to program, position, and number of years in teaching. Notably, results exclaimed that one of the college in Western Visayas is producing graduates who are viable to the academic institution where they teach. Furthermore, the school should not remain complacent considering the fast-changing advancement in the educational arena. Thus, the school administration and the dean of the college of education should closely monitor and evaluate the effectiveness of the varied teaching strategies used by teachers ensuring that it enhance students’ communication, creativeness, and critical thinking skills.

COVID-19 has created a global serious health hazard with far-reaching consequences for society, our perceptions of the world, and how we live our daily lives. As a result, the World Health Organization recommended the use of face masks and social isolation to help reduce the rising number of infections. However, subsequent research has revealed that face masks alone can be ineffective, particularly in crowded settings or hospitals. Face shields can also be used in addition or as an alternative for face masks because they are indefinitely reusable and can be washed with soap and water or standard disinfectants. Because most detectors for fighting COVID-19 only focus on the face mask alone, we proposed a transfer learning model by fine-tuning the pre-trained MobilenetV2 architecture, to detect, recognize, and distinguish faces with shield, mask, and those without either. This study applied a standard image recognition pipeline, which is comparable to that used by most traditional recognition programs. In doing this, we first downloaded and scrapped images from search engines to form our dataset, we then pre-processed the images by the application of image augmentation to address the limited availability of the dataset for a better training and validation. After which a multi-class detection system was accomplished. The results of the study achieved 98 percent accuracy on the validated dataset. It is therefore recommended that this model can be improved to capture all forms of face covering and be integrated into CCTV cameras for its detection in important places like hospitals.
