Abstract
Industry 4.0 offers new opportunities in teaching and learning with the emergence of new ideas and technology. Face-to-face instruction becomes an obsolete method and does not cater to the needs of millennial learners. Distance learning is not widely adopted by schools in third world countries. Thus, school policies, facilities, and teacher is not yet ready to adapt full online learning instruction. However, Blended learning mediates the transition of face-to-face and online learning approach. This study examines the 180 senior high school students in Science, Technology, Engineering and Mathematics Strand on their perception on the use of eLearning tools and the impact of blended learning on their learning process. This study used the descriptive correlational design using a questionnaire in gathering data. Results show that respondents preferred the blended learning approach for its flexibility in accessing content online and highly adept in using digital devices. The use of eLearning tools is highly engaging and efficient; however, blended learning model has a moderate impact on students’ performance in doing activities online.

Abstract
The paper clarified the development of the analytic geometry flipped classroom teaching model through Google Classroom. The model of teaching was developed based on the significant definition of flipped classroom that reverses the traditional teaching method. The flipped classroom was known as the active learning that provided lecture before the classroom via video recorded or online and then face-to-face teacher guiding for practicing, doing projects, or problem solving in classroom. The flipped classroom, therefore, probably allow students to learn productively active learning about mathematics (e.g. analytic geometry) with teacher in classroom. And, the open online instructional platform Google Classroom could be used by all teachers to provide the online lecture before practicing, doing projects, or problem solving in classroom. The paper clarified the development of the analytic geometry flipped classroom teaching model through Google Classroom regarding on 5 strategies of effective flipped classroom including plan, introduce concepts in class, use math apps, video, and student teaching. Then, the paper explained more details of the analytic geometry flipped classroom learning activities. The paper may have implications for developing mathematics active learning via the flipped classroom.

Abstract
STEM stands for Science, Technology, Engineering and Mathematics integrated to be an educational management approach. It also enhances students’ thirteen science process skills including observing, classifying, measuring, using numbers, using space/time relationship, inferring, predicting, communicating, identifying and controlling variables, defining variables operationally, formulating hypotheses, experimenting, interpreting data and drawing conclusion. These are divided into two groups: basic process skills consisting of the first eight processes and integrated process skills consisting of the last five processes. Nowadays, there are plenty of studies concerning the STEM Education effected on students’ science achievements in Thailand but not many focusing on science process skills. Therefore, the objective of this research is to synthesize the STEM Education effected on Thai students’ science process skills. The variables consist of two sets which are the description of research, and the effect sizes of research. The tool for collecting data is the recording data form for research synthesis. Data were analysed by frequency, percentage and meta-analysis. The results showed that 1) the description of research found that from 2010 until 2019 research referring to students’ science process skills on STEM Education published ten reports, mostly in 2016 and 2018 (40%), Maha Sarakham University and Rajabhat Maha Sarakham University equally usually produced the research referring to the students’ science process skills on STEM Education (30%), most researchers from the Office of the Basic Education Organization produced the research (90%), most were female researchers (80%), the research type was thesis in master degree (100%), the objective commonly found was to compare (44%), most of the research design found was in experimental design using One Group Pretest - Posttest Design (80%), always found sampling methods using cluster random samplings (50%), sample found mainly was students (100%), samples’ research level was equally both lower and upper secondary (50%),used largely in science (50%) and repeated analyzing method found was descriptive statistics (27.02%), and most of the science process skills were integrated skills (60%). 2) The effect sizes (d) of STEM Education effected on students’ science process skills was 1.69.

Published: April 2021

Abstract
Due to a recent educational reform in Thailand, elementary teachers are challenged to use an engineering design process as an instructional approach to STEM education. This would require them to have a design thinking mindset (DTM) as a basic requirement. However, it has been argued that it is difficult to measure DTM using a questionnaire. Therefore, there has been little information if Thai elementary teachers possess DTM. This study aimed to develop and validate a Thai version of DTM questionnaire with two groups of Thai elementary teachers (N=138). Successively determinding Cronbach’s alpha values with each group of the teachers, six components of DTM were suggested. These components included (1) Being comfortable with problems, (2) User empathy, (3) Mindfulness of the process, (4) Collaborative working with diversity, (5) Orientation to learning, and (6) Creative confidence. While this result may need to be comfirmed with a larger population of teachers, a Thai version of the questionnaire can be potentially used to explore Thai elementary teachers’ DTM in other contexts.

Published: April 2021

Abstract
Mathematics education can be daunting for students — due to a variety of societal factors and abilities in mathematics that are often seen as fixed. Teachers expressed that student – centered approaches promote active learning in the classroom. Active learning requires students to do meaningful learning activities and think about what they are doing. This study sought to find out the comparison of three active learning models (ALM) in relation to the achievement and retention in mathematics among Grade 11 students. This study was conducted in one of the private schools in Cagayan de Oro City during the first semester of 2018-2019 among 84 students under Science, Technology Engineering and Mathematics (STEM) strand. The results of the study revealed that the respondents from each model had significantly increased results of their achievement scores within the two weeks implementation. Furthermore, the three models had the same effect in terms of retention of mathematics concepts. During the focus group discussion students expressed that clear directions and giving feedback on their work helped them solve the problem. In addition, they also conveyed that listening to peers ideas motivated them to be successful in solving a problem.

Published: April 2021

Abstract
The article talks about the awareness of preschool students about the impact of the 4.0 industrial revolution in education. Research results show that: Most of the students in the University and College of Education are aware of the importance and impacts of the 4.0 industrial revolution in education in general and in the changes of goals, contents, methods, and forms from the impact of 4.0 industrial revolution. However, there still have been sparities between students of Universities and Colleges of Education, which show that students at universities of education are better aware of the others at the College of Education. And, there are still some students who are not really aware of the changes in the goals, contents, methods and forms of education from the impacts of the 4.0 industrial revolution. However, STEM education also significantly affects the change of teaching methods, towards interdisciplinary teaching and development of learners skills through many experiential activities to adapt and integrate.

Authors: Madmanang Romsan , Sriwiriyarat Tongchai 
Published: April 2021

Abstract
Salinity or saltiness is dissolved in water by the relative proportion of salt in a solution. All organisms have to keep their cells alive a water balance in their bodies. The activated sludge process (ASP) containing aerobic microorganisms located nearby the coastal area may be faced the problems of salinity from sea water. In this research, the effects of salinity on the respirometric activities of mixed culture bacteria from activated sludge process were evaluated at different levels of NaCl concentrations ranging between 0-25 g/L in the OxiTop system at the temperature of 20 °C. The oxygen uptake rate (OUR) was used to reveal the effects of salinity. The experiments results indicated that the OURs decreased as the NaCl concentrations increased, resulting in the failures of bacterial osmotic pressure systems and causing the lysis of bacteria. The COD and nitrification were failed because the nitrogen and COD loadings to the systems were increased by the lysis of bacteria.

Published: April 2021

Abstract
Today’s consumers are becoming health conscious and this has led to the demand of fruits and vegetable which wastes like the rinds, skins or peels from such are also produced. This study aimed to divert wastes into an innovative food product. Specifically it aimed to utilize watermelon rind and ponkan peelings into marmalade. A quantitative research method is used in the analysis of this study. Four treatments of marmalade were prepared and the most acceptable treatment was analyzed for physicochemical properties. Research results showed that the four treatments of marmalade are acceptable and do not have significant differences in terms of its characteristics and general acceptability. Among the four treatments, T 277 and 482 are the most acceptable with a computed value of 7.73 which means liked very much. The physicochemical analysis of T 277 results (pH-5.39, TA-0.360, WA- 26.66%, TSS-66.3%, Vit. C-below DL, Ash-0.53, Fat-0.85%) are more acceptable as compared with T 482 (pH-5.398, TA-0.354, WA-31.32%, TSS-56.4%, Vit. C-below DL, Ash- 0.71 Fat-0.36%). Furthermore, for the sample’s microbial load count, treatment 277 has lesser microbial load which is 70 and 60 CFU respectively while treatment 482 has 70 and 100 CFU in the two batches of samples which were analyzed. Thus in terms of physicochemical properties and microbial analysis, T 277 is more ideal. From the results of the study conducted, it is concluded that the acceptable ratio should be 2:1 that is 400 grams watermelon rind to 200 grams ponkan juice. Specifically, the measurement of ingredients is found to be within a good proportion for marmalade making. A techno-guide on Watermelon Rind Marmalade was then developed showcasing its physico-chemical properties, recipe and costs.

Published: April 2021

Abstract
High speed collision is the main feature of armored service environment. It is very important for armor structure design to study the dynamic response of armor material under high strain rate loading. Based on Hopkinson bar techniques, dynamic performance experiments of high-nitrogen steel under combined loading were carried out in this paper. The stress-strain curves of high nitrogen steel under different loading conditions were obtained. The results show that with the increase of shear stress ratio, the anti-failure ability of high nitrogen steel decreases significantly. When the loading angle was 90° and 60°, the fracture surfaces and stress-strain curves of the samples were significantly different under the same loading conditions. With the decrease of the loading angle, the fracture surface and the stress-strain curve of the sample under the same loading condition tend to be the same. In the process of combined loading, with the reduction of the loading angle, the tensile force of the sample at the yield stage decreases gradually.
