Abstract

The purpose of this research is to reveal the relationship of thinking level with the students’ ability to form a representation of proposition network on the human nervous system concept using modeling based learning. This was quantitative research with 30 science class’ students of grade XI from one private school in Bandung as the subject research, who learned using modeling-based learning (MbL). The instruments used to measure the thinking level were 19 numbers of multiple choices and 2 essays that were developed based on Marzano and Kendall’s level thinking indicator. The result of this research shows that the thinking level of senior high school’ students has reached L3 (analysis) with minimum standard mastery ≥70. The higher the expectation of students’ thinking level, the lower the minimum standard mastery will be reached. The correlation result showS no significant relationship between thinking level and the students’ ability to form a proposition network on the study of neuron structure and function (r= 0,075; p=0,692) with low concept complexity. The significant relationship between thinking level and the ability to form proposition representation is obtained during the study of the central nervous and peripheral nervous system (r= 0,506; p= 0,004) with higher concept complexity. It means the higher students’ thinking level, the better their abilities to form a proposition network. MbL could be recommended for learning biology concept especially abstract concept like the human nervous system. This research concluded that students’ thinking level reached level 3 (analysis) and MbL can facilitate a significant relationship between thinking level and the ability to form proposition networks if the concept taught has a higher complexity compared to the lower complexity concept.

Abstract

The purpose of this study is to validate the measure of student attitudes toward science, technology, engineering, and mathematics (S-STEM). This study used the cross-sectional design to employ translation and cultural adaptation as well as providing evidence of the reliability and validity of the S-STEM. The instrument was administered to 748 pre-university students in Penang, Malaysia. Data were analyzed using confirmatory factor analysis (CFA) with AMOS 19.0. Results support S-STEM as a three-factor multidimensional construct, namely attitude towards science, attitude towards technology/engineering, and attitude towards mathematics. All statistics such as factor loadings, average variance explained, construct reliability, evidence of discriminant validity, and goodnessof-fit indices were found to be at acceptable values. These positive results are significant because although the instrument has undergone numerous modifications, such as translation and others, the generalizability of the instrument is still preserved in pre-university Malaysian students. Counselors may administer the instrument to facilitate the choice of courses to enroll at university. The research may utilize the instrument to gather data in providing measures to improve students’ participation in learning STEM. The practical implications, as well as the methodological limitations of the present study, are discussed.

Abstract

The explanatory mixed-method was conducted to assess prospective biology teachers’ (PBTs) perceptions on thinking as 21st century skills. Data were collected using a quantitative survey method, and an interview with PBTs from Islamic University. 168 (14 men and 154 women) of 195 PBTs participated in filling out the questionnaire. The questionnaire consisted of 24 statements of aspects of critical thinking, problem-solving, creativity, metacognition of the 21st century skill. The confirmatory factor analysis (CFA) and alpha Cronbach tests were used to determine the quality of the instrument. Statistic descriptive, ANOVA, and correlation tests were conducted to analyze the quantitative data. Triangulation was conducted on the results of the interview. The results of the study indicate that (a) most male and female PBTs at Islamic universities have high skills in critical thinking and metacognition; (b) most male and female PBTs at Islamic universities have insufficient skills in problemsolving and creativity skills; (c) the results of this study also showed that there is no relationship between gender and PBTs skills. This study suggested that teachers and education managers in Islamic universities need to apply integrative learning by paying attention to the skills needed by PBTs. Learning applied in classrooms should be based on 21st century skills.

Abstract

As one of the logical consequences of the transformation process from agricultural to industrial societies, human activities contribute some pressures to our environment, especially air quality. Kalimantan Island, as the third-largest island on Earth, expected to be the world’s lungs, transboundary massive haze problems frequently occurred on this island, especially between 2011-2015. Since the fire forest started from the Indonesia side of this island, reliable information about air quality in Kalimantan-Indonesia and environmental education’s urgency toward this result becomes essential to explore. Air Quality Index (AQI) is measured by a passive sampling method with SO2 dan NO2 as pollutants’ parameters. These two parameters are recognized as a valid measurement of air pollutants, strongly affect human health, and are understandable by ordinary citizens, especially middle school level students. AQI reached 94.27, which is categorized as a good-quality index. Among the provinces, the highest AQI was reached by East and North Kalimantan with 97.63, while South Kalimantan has the lowest with 91.41. Furthermore, the NO2 parameter contributed much larger than SO2 parameters in all provinces. AQI Kalimantan tends to increase, although South Kalimantan tended to have a lower air quality index than other provinces from year to year. This result drives comprehensive support from the education sector to build environmental understanding. From an educational perspective, this result shows the urgency of enhancing science education with air quality discussion. We suggest a possible enhancement in substance and its transformation section and the Science-Environment-Technology-Society section in Science for Junior and Senior High School. The procedure of AQI measurement and the urgency of maintaining AQI are needed to be integrated into the science curriculum.

Abstract

Utilizing serious games as teaching aid can stimulate students’ interest in learning and enhancing students’ understanding of STEM learning. The use of serious game on learning analytics for STEM learning provides assessment data to measure students’ performances and achievements of predefined learning outcomes. While numerous researches on learning analytic in serious games have been conducted, studies on their association with STEM learning are scarce. Past studies also indicate that teachers use serious games in teaching but yet to utilize serious games as assessment tools. This situation leads to the need of developing a conceptual model of learning analytics in serious games for STEM education (APPS-STEM). The conceptual model was initially developed through the focus group approach and literature review to examine the learning metrics of serious games, which is appropriate for STEM learning before being verified by experts. Based on the result from expert review, the conceptual model of APPS-STEM contains nine themes, namely effectiveness, problem-solving thinking and creativity, flexibility, key stakeholders, emotions, serious game design, curriculum profiles, learning profiles, and target user norms. This conceptual model is expected to serve as a guide for stakeholders to implement learning analytics in serious games design for STEM learning. Further study will be the development of serious game prototypes to determine the effectiveness of the APPS-STEM model in the STEM learning paradigm.

Abstract

Ex-mining pond water is widely used for the daily needs of the people these days, such as bathing, washing, and even drinking. Over time, it turns out that coal mine acid water has polluted the environment. The use of membrane technology to produce water that meets drinking water quality standards by the Minister of Health Regulation No. 492 of 2010 can be a solution to this problem. The NF270 membrane is a membrane process between reverse osmosis and ultrafiltration, which has a lower flux and operating pressure below 0.2-1.53 Mpa compared to reverse osmosis. Membrane NF270 is used for the reclamation of wastewater, water purification and softening, seawater desalination, and others. Its high rejection of organic molecules with a molecular weight of 200-2000 Da ions and multivalent can remove suspended solids, natural organic matter, bacteria, viruses, salts, and divalent ions contained in water, including coal mine acid water. The purpose of treating acid mine drainage with the NF270 membrane is to remove COD, TSS, TDS, and Fe metals. The NF270 membrane was used in this study to treat the coal mine acid water of PT. Bukit Asam. The performance of the NF270 process was assessed from the effect of pressure (4, 5, and 6 bar) on the flux and rejection rate of each parameter in a single solution, mixed and aqueous coal mine acid solution. The optimum pressure of the NF270 membrane for all parameters was 6 bar. This optimum pressure was then used to compare the phenomenon of flux that occurred and the level of rejection produced in the original sample of coal mine acid water. In the original coal mine acid water, there was a significant decrease in flux due to fouling deposition on the membrane surface. This phenomenon of decreasing flux was caused by fouling and polarization concentration. The rejection rates produced for the parameters of COD, TSS, TDS, and Fe with NF270 membranes were 56.4-93.1%; 78.5-100%; 43-69.3%; 67-100% respectively. Treated coal mine acid water using NF270 membrane technology can be used as drinking water that meets the standards of the Indonesian Ministry of Health Regulation. Thus, NF270 membrane technology can be used to process coal mine acid water into environmentally friendly drinking water.
