Published: August 2019

In this research, the effects of STEM (Science-Technology-Mathematics-Engineering) activities on academic achievement of prospective teachers were researched, their opinions on STEM activities were sought. The research was based on a semi-experimental model with pre-test and post-test control group. During the application phase, the topic of Work-Energy subject was taught through STEM based 5E model in the experimental group, while in the control group, the lessons were conducted using traditional teacher centred teaching. The research group is comprised of second-year students in Elementary Mathematics Education taking Physics I course at the Dokuz Eylul University in Turkey. A statistically significant difference was found in favour of the experimental group in terms of prospective teachers’ academic achievement. In addition, the positive opinions of the prospective teachers from the experimental group on STEM activities were that STEM activities included encouraging group work, assisting students to produce original work, enabling them to do research, and ensuring that the information learned is permanent. The negative opinions of them on STEM activities were insufficient time for the application, the dominance of some students during the group work, and difficulties with noise levels in class.
ADOPTING IDEAS FROM CURRENT NORDIC TEACHER EDUCATION STRATEGIES TO INITIAL SCIENCE TEACHER EDUCATION
Authors: Lavonen Jari
Published: August 2019

A key goal of initial teacher education in all countries is to educate quality teachers through a quality post-secondary programme and then support them in their careers through professional learning. However, there are different definitions and interpretations of a quality teacher or a quality teacher education programme. Several terms are used to describe a quality teacher, such as professional, effective, competent, expert, or ideal (Stronge & Hindman, 2003; Goel, Bell, & Little, 2008). Furthermore, the definition of a quality teacher changes continuously and follows the current trends of society and working life. Consequently, national-level teacher education strategies and teacher education programmes are continuously improved. In the Nordic region, all countries have been developing initial teacher education at the national and institutional levels over the last five years. In this editorial, I will briefly analyse the aims of new Finnish, Norwegian, and Swedish national-level teacher education strategies. Then I will briefly discuss how we can improve science teacher education according to the new strategies.

EXPLORING THE EFFECT OF NOS/NOT LEARNING AND DISPOSITIONS ON UNDERTAKING BEHAVIOURAL ACTIONS IN THE CASE OF NATURAL HAZARDS
Authors: Cerulli David A. , Holbrook Jack B.
Published: August 2019

This research seeks to evaluate students’ intended behavioural actions in the event of a natural hazard, specifically hurricane, lightning, earthquake, or tsunami. A test instrument, measuring behavioural actions in the event of a natural hazard, and related NOS/NOT beliefs and dispositions, is utilized to collect data in Estonia, USA and Japan (N=2323). Results suggest that students responded adequately to tsunamis and lightning strikes, but to a lesser extent for hurricanes and earthquakes. Results also suggest a connection between dispositions and behavioural actions, but a lack of connection between generalised. NOS/NOT conceptualisations and behavioural actions. Results imply that students find it difficult to apply their learning to new situations requiring responsible behavioural actions. Implications indicate that NOS/NOT are not well understood, while responsible behavioural actions need to more heavily stressed in teaching about natural hazards involving the promotion of student values and attitudes with respect to Natural Disaster Reduction (NDR).
Keywords: behavioural action, Natural Disaster Reduction (NDR), dispositions, Natural Hazards (NH), Nature of Science (NOS), Nature of Technology (NOT).

Authors: Fadzil Hidayah Mohd , Saat Rohaida Mohd , Awang Khalijah , Hasan Adli Durriyyah Sharifah
Published: August 2019

Science education is facing an immense challenge due to students’ lack of engagement with science education. This issue calls for a collaborative and integrative teaching strategy such as the Scientist-Teacher-Student Partnership (STSP). This research employed a qualitative research methodology supported by quantitative data, to explore students’ perceptions of learning science through STSP. It involved 125 students in Grade 10 from four schools, eight science teachers and seven scientists from a university situated in Kuala Lumpur. The data were collected through survey questionnaire and interviews. The collected qualitative data were analysed using constant comparative techniques and the quantitative data arising from the responses of the survey were calculated as mean scores and standard deviations. The findings showed that the tripartite collaboration brings educational benefits to all groups. Based on the student’ perspective, four (4) main themes emerged. The students found that 1) the partnership enriched their learning experiences, 2) they acquired procedural skills through hands-on experiments, 3) they had the opportunity to explore emerging topics in science, and 4) they were exposed to various career opportunities in STEM-related fields. This research has promoted greater articulation of STSP as a mechanism for educational reform in STEM.
Keywords: authentic science, qualitative methodology, Scientist-teacher-student partnership (STSP), STEM.
EXAMINING SECONDARY SCHOOL STUDENTS’ MISCONCEPTIONS ABOUT THE HUMAN BODY: CORRELATIONS BETWEEN THE METHODS OF DRAWING AND OPEN-ENDED QUESTIONS
Authors: Fančovičová Jana , Prokop Pavol
Published: August 2019

Students of various age groups manifest numerous explanations that differ from what is known to be scientifically correct. Misconceptions about the human body are one of the best studied areas of students’ understanding of scientific phenomena. To explore misconceptions, researchers have at their disposal various methods which can lead to different results. In order to find an effective, cheap and representative diagnostic instrument, correlations between scores obtained by open-ended questions and drawings on the example of the human circulatory system were examined. Open-ended questions provide a more complete understanding of student learning but are harder to evaluate objectively in comparison with drawings, particularly in cross-cultural research. Correlations among scores obtained by these two methods in the present research were moderate, which suggests that drawings reflect students’ understanding of the circulatory system, albeit not perfectly. Although drawings probably never provide a complete understanding of children’s ideas about science, this cheap and time effective method is recommended particularly in cross-cultural research, where standard, comparable conditions are hard to achieve.
Keywords: circulatory system, human heart, human body, students’ ideas.

Authors: Gavora Peter , Wiegerová Adriana
Published: August 2019

Professional beliefs is an important factor that influences activities that preschool teachers organize and manage in the classroom. In order to determine how strong these beliefs are, valid and reliable instruments must be at disposal. This research aimed to develop and validate DPBA, an instrument designed to measure teachers´ beliefs toward the use of inquiry-based activities in preschool classes. A sample of 1,004 Czech preschool teachers was used to obtain the validation data. From the initial set of 40 items, a final version of DPBA with 22 items was created in a series of analyses. Principal component and maximum likelihood methods with Varimax rotation were used to extract an appropriate scale structure. DPBA is composed of three subscales, Benefits (12 items), Teacher competence (6 items) and Concerns (4 items), which have reliabilities of .906; .847 and .729, respectively. The overall reliability of the instrument is .883. Consistently high reliability coefficients were obtained in subsamples of respondents of varied years of practice and education, thus verifying a solid internal consistency of the instrument. Confirmatory factor analysis proved a theoretical model with the three subscales with adequate model fit indices. Overall, DPBA possesses sound psychometric properties when used with Czech preschool teachers. Keywords: inquiry-based activities, preschool teacher, instrument development, teacher beliefs.
EFFECTIVENESS OF THE CONCEPTUAL CHANGE METHOD ON UNDERSTANDING PLANT MASS INCREASE
Authors: Gobec Katja , Strgar Jelka
Published: August 2019

This research aimed to assess the influence of the method of conceptual change on understanding the concept of increasing the mass of plants among 414 students in agricultural education in Slovenia. In photosynthesis, biomass is produced, so understanding these processes is essential for successful agriculture. Data were collected using a knowledge test and a questionnaire that were administered before and after the traditional and experimental teaching units. The results allowed the conclusion that the method of the conceptual change (experimental teaching unit) was significantly more effective than the traditional method in improving the understanding of the contribution of solar energy and carbon dioxide to the increase in the mass of plants. There was no significant difference in the improvement of knowledge about the contribution of the minerals that plants receive through their roots. Understanding the contribution of water to the increase of the mass should be tested further because of the unexpected misconception that influenced the results that was found among students. Students’ attitudes toward biology and photosynthesis were significantly better after the experimental teaching unit. Considering these findings, other topics should be prepared using the method of the conceptual change to assist biology and science teachers in agricultural education.
Keywords: agricultural education, biology education, conceptual change, photosynthesis, plant mass.

Published: August 2019

This research uses board games as teaching material to develop students’ decision-making ability and basic scientific literacy and to foster students’ value for nature and social caring by working with socioscientific issues. The board game structure contains four perspective systems: ecological, economic, cultural, and political. In the game processing, students must handle, consider, and understand the different role players’ positions and face different missions that involve socioeconomic and environmental conflicts. When making any decisions, students affect the follow-up game behaviors and develop tendencies. The board game instruction was field-tested with 38 high-school students from two different high schools. Students played the board game for a total of 200 minutes. Students’ scientific conceptions concerning biodiversity (closed-ended) and perspectives on socioscientific issues (open-ended) were assessed before and after the board game lesson. The results showed that students in both high schools significantly increased their understanding of biodiversity concepts, with a high level of effect size (Cohen's d equal to 1.40 and 1.06, respectively, for the two schools). In the semistructured interviews, the interviewed students were able to reflect on the value of animals and provide various opinions about animal conservation and economic development. Keywords: board game, decision making, descriptive research, game base learning, socioscientific issue.

Published: August 2019

Arsenic is a toxic metal found as inorganic oxyanion arsenate As(V) and arsenite As (III) species. The disposal of toxic heavy metals such as arsenic poses high risk to environment. The present study was undertaken to isolate arsenic-metabolizing bacteria from arsenic contaminated soil of Chandpur district, which is one of the most arsenic contaminated area in Bangladesh and later these bacteria were screened for their ability to metabolize arsenate. Out of ninety eight isolates, ten were found to be capable of metabolizing arsenic in Yeast Extract Mannitol (YEM) medium containing 2 mM arsenate at 37ºC. One of the bacterial isolates designated as I-25 was found to produce an extracellular enzyme which can reduce As(V) into As(III) and able to grow in presence of up to 500 mM arsenate. Subsequent molecular identification of this enzyme producing bacterial isolate using 16s rRNA sequence analysis was correlated with previously identified isolate as Bacillus aryabhatti. Further characterization of the enzyme showed that optimum pH of the extracellular enzyme by the bacterial species was 7 and optimum temperature for the enzyme activity was 60ºC. The bacterial isolates can be exploited for the study of possible bioremediation of arsenic contamination.

Published: August 2019

The Satyrinae is a subfamily of Nymphalid butterfly, which is morphologically and ecologically the most diverse group, occurring in all habitats. In the present study, Cytochrome c oxidase subunit I (COI) gene of seven species of Satyrinae was sequenced, aligned, and used to construct phylogenetic trees. The molecular identification of these Satyrinae species was confirmed by comparing the related sequences in the National Center for Biotechnology Information (NCBI) GenBank. The base compositions of the COI sequences were 39.07% T, 16.44% C, 29.83% A, and 14.64% G, revealing a strong AT bias (68.9%). The sequence distance among Satyrinae species ranged from 0.09% to 0.18%. Phylogenetic trees were constructed by the neighbor-joining (NJ) and maximum likelihood (ML) methods, using Orthetrum sabina as an outgroup. Both trees had almost identical topologies. The sampled species in Satyrinae exhibited the following relationships: Melanitis leda + [(Mycalesis mineus+(Mycalesis gotama+Mycalesis anaxias)) + (Ypthima baldus + (Lethe chandica+Elymnias hypermnestra))], suggesting that M. leda might be distantly related with the rest of the Satyrinae species. This clustering result is almost identical to current traditional classification. This study confirms that the COI based DNA barcoding is an efficient method for the identification of butterflies including Satyrinae species and, as such, may further contribute effectively to biodiversity and evolutionary research.

MODERN APPROACH TO ARTERIAL HYPERTENSION IN THE CIRCUMPOLAR AND ARCTIC REGIONS. LITERATURE REVIEW
Authors: Hasnulin V I , Voevoda M I , Hasnulin P V , Artamonova O G
Published: August 2019

A new approach to the problem of significant youthification of arterial hypertension and its fast progression in non-indigenous populations of the polar and arctic regions has been presented. The hypertension progression in high latitudes is combined with influence of climate change biological stressful pace in the Arctic area and influence of adverse space, geophysical, weather, chronobiologi-cal factors. Research scientists of the Russian polar and arctic regions have identified a number of leading elements of the northern climatic-geographic chronic stress which make the main contribution to formation and progression of hypertension in the North. The most characteristic manifestations of climatic-geographic stress in uncomfortable and extreme regions of the North and Siberia are reactions of the central nervous and endocrine systems, metabolic changes and development of "oxidative stress". In addition to these manifestations the polisindromatic climatic stress may include: deficit of detoxification processes and barrier organs, northern metabolic type disorders, northern tissue hypoxia, immune deficiency, blood hypercoagulation, multiple endocrine disorders, regenerative and plastic failure, violation of electromagnetic homeostasis, functional dissymmetry of interhemispheric relations, desynchronosis, emotional stress, meteopathies. Obviously, creation of advanced innovative preventive and therapeutic technologies to reduce spread of hypertension among population in the polar and arctic regions require active study of the northern stress mechanisms' role in progression of this severe cardiovascular pathology.
HOSPITAL SURVEILLANCE OF HEALTHCARE-ASSOCIATED INFECTIONS: REPEATED PREVALENCE SURVEYS
Authors: Krieger E A , Samodova O V , Grjibovski A M
Published: August 2019

This paper presents an approach to implementing institution-wide surveillance of healthcare-associated infections by means of regular point-prevalence surveys. We explain the methods of data collection and statistical analysis in details. Healthcare-associated infections are defined as localized or systemic conditions which was not present on admission or within the first 48 hour of hospital stay (or 30 days for surgical site infections). The prevalence of different categories of healthcare-associated infections varies in different hospitals that can be explained by variations in hospital stocks, types of medical units, treatment, age of patients and others. According to different published sources, the incidence of healthcare-associated infections in Russia exceeds the official data. An inconstancy in published results probably indicates under-registration of healthcare-associated infections and demonstrates a need for alternative surveillance measures to provide a basis to enhance the practice of infection control. Repeated prevalence surveys are known as simple surveillance options, which are efficiently used in the European countries. This method allows to obtain data on prevalence of different categories of healthcare-associated infections and factors associated with occurrence of infections in different hospital units. The results allows to identify areas requiring improvement in the hospital and develop specific prevention strategy for every hospital unit.

The epicenter was Awaran Baluchistan which directly affected about 300,000 people leaving about 386 causalities. The impact of this earthquake was so much large that it created a new landmass which was named as Zalzala Koh later. It was the result of strike slip faulting at a depth of 15km. The new born island was full of rich minerals, gases and dead sea animals. This island was 60 feet high, 100 feet wide and 250 feet long. The classification results of Landsat 8 show that the island completely disappeared in 2019 after 6 six years of its birth. First the volume of this island decreases due to reduced pressure of internal gases and secondly, the high-pressure water waves vanished it completely. Satellite imagery proved efficient for spatio-temporal monitoring of various landuse classes.

Distribution of heritage To People Which made lost (mafqud) According to Islamic Law
Authors: Ardhani Anindita Atibhakti
Published: August 2019

The purpose of this study is to understand the division of inheritance against people who are declared missing (mafqud) according to Islamic law. The problems examined in this study concerning legal certainty for heirs who were declared missing (mafqud) in the right to inherit and distribution of inheritance after the person declared missing (mafqud) is known to exist. The research method used is normative legal research. The results of the study are the heirs who lost (mafqud) still have rights, be they rights to property or inheritance. This right remains attached as it is when it is still in normal life. When the heirs leave the residence for a considerable time, then their status becomes a lost person (mafqud), then their life status is still recognized. The mafqud heirs mentioned above are part of the heirs due to blood relations (caused by birth) based on the An-Nisa surah, especially verses 7 and 8. Furthermore, the inheritance case for the mafqud heirs whose existence is known, can still obtain the inheritance part even though the portion has been spent by other heirs, because in fact the heirs who were declared missing or the mafqud may have a substitute heir who will replace the position of the heirs declared mafqud when the inheritance is distributed to the heirs as stipulated in Article 185 verses (1) and (2) KHI.
