The grading systems used for assessment students' knowledge in traditional and distance learning differ and give different assessments of learning outcomes, which affects the indicators of student academic performance. The trends of modern education are aimed at the increasing involvement of distance forms in the educational process of universities, which requires a certain synchronization of grading systems at the level of learning outcomes. The research is aimed at identification and confirmation of the existence of differences between the results of assessment in traditional and distance learning forms, which are reflected in the indicators of student performance. The study used methods of nonparametric analysis using the STATISTICA 10.0 program. The Mann-Whitney U-test was used to compare independent populations in cases where there were no signs of normal data distribution, and Pearson's Chi-square test was used to compare nominal values. To compare related (paired) quantitative samples, the Wilcoxon test was used. The research results showed a statistically significant increase in student academic performance during the COVID-19 pandemic during distance learning. Therefore, when comparing the indicators of student performance in the spring semesters of 2018/2019 and 2019/2020 academic years, significant differences were found in the U-criterion and Chi-square with different levels (p <0.05, p <0.01, p <0.001) depending on the course of study and the performance indicator. The only exceptions are the senior students of Master's programmes who have shown a decline in academic performance. According to the results of the study, it can be concluded that the distance grading system makes lower requirements for learning outcomes in terms of student academic performance indicators, which overestimates them relative to the traditional form of education.

The problem of the study. The conventional assessment methods used in evaluating the academic achievement of students have been saddled with deficiencies. Research methods. This study examined the effect of assessment for learning method on students’ academic achievement in carpentry and joinery works in technical colleges in Edo and Delta States, Nigeria using quasi-experimental research design. The population for this study comprised of 430 students and the sample size was 68 vocational II carpentry and joinery students from two intact classes randomly drawn from the 12 technical colleges in Edo and Delta States. The instrument used for data collection was Carpentry and Joinery Works Achievement Test (CJWAT) developed by the researcher from NBTE curriculum. The instrument was tested by three experts. The reliability of CJWAT was calculated using Kuder Richardson formulae 21 (KR-21) and a reliability coefficient of .78 was achieved. Mean and standard deviation were used to address study questions whereas one-way and two-way Covariance Analysis (ANCOVA) were used to evaluate hypotheses at a .05 level of significance. Results. The study's findings revealed that the learning method assessment (9.43) had a higher achievement score than the traditional method of assessment (5.25), indicating that the learning method assessment had a greater impact on student achievement in carpentry and carpentry than the traditional method of assessment. One-way ANCOVA result, F(1,77) = 56.75, p = .000 indicates a significant difference between the two assessment methods with regards to students’ achievement in carpentry and joinery trade. Female students (9.34) find the Assessment for Learning Method to be marginally more effective than male students (9.30). On the other hand, the Two-way ANCOVA result, F(1,75) = 1.83, p = .180 shows no significant difference between the academic achievement scores in carpentry and joinery trade of the students’ based on gender. It is therefore concluded that there is a significant difference between the mean achievement scores of students assessed with Assessment for Learning method and those assesses with the conventional assessment method in favour of assessment for learning method and no significant difference between the mean achievement scores of male and female students assessed with assessment for learning method at post-test. Conclusion. It was proposed, among other items, that the government and all stakeholders organize and fund seminars, conferences and workshops for technical teachers on a regular basis to attend and learn how to adopt assessment for learning method in educational institutions through the application of rubrics and portfolios.

The multicultural nature of the environment in which the modern educational process is carried out imposes on the teacher the obligation to be able to work with children of different ethnic groups, different beliefs, from different cultures. Since, in practice, most novice teachers are not ready for effective activity in a multicultural environment, the purpose of the research was to study training pedagogical students to work in a multicultural environment. In the research the following methods were used: analysis of pedagogical literature on the issue; pedagogical experiment (the one group pretest-post-test design); diagnostic techniques, including interviewing pedagogical undergraduate students, ranking of activities to train to work in a multicultural environment. The experiment involved junior students (I-II year) and senior students (IV-V year) of the South Ural State Humanitarian Pedagogical University, studying in the direction of “Pedagogical education (with two training profiles)”, where the second profile is English (84 respondents). After the pedagogical experiment, self-assessment of students' readiness to work in a multicultural environment improved: at the final stage of the experiment, on the basis of the sign test (G-criterion) at a significance level of 0.01, statistically significant differences were revealed between the pre-experimental and post-experimental values of self-esteem. The obtained empirical value of the criterion, equal to 7 (Gemp = 7), is less than the critical one (Gctit = 19), which indicates the transition of the group to a higher level of readiness to work in a multicultural environment. The preferences of the types of activity during the experiment changed: before the experiment, students chose the activity-based component of training, after the experiment they preferred information-based component. The results indicate that in order to train pedagogical students to work in a multicultural environment, a complex of activities, including both information-based and activity-based components of education, is to be applied. It was concluded that special attention should be paid to the study of the cultures of countries from which a vast number of migrants came to Russia, as well as to elements of conflictological education. The applied part of teacher training should include school-based experience in teaching classes with multicultural students.

Published: September 2021

The key role of this research is a comparison between traditional strategic transport modelling of intersections of a road network with the real-time observed and calculated data. The significance of this research is to evaluate the traditional strategic transport modelling on mesoscopic level, which able to study the network level impacts of smaller traffic engineering and traffic management interventions in a precise way. This research attempts to quantify the correlation between highway intersection capacity and traffic parameters, for this there is a need to determine the capacity values of different node types. This situation gives rise to a question that is dealt with in this research. "How different traffic parameters can be interrelated with the capacity of intersections by using different simulations?". This paper used assignment procedure, and usage of real-time data set with the calibration of Budapest Transport Model. Five contiguous intersections are selected on a small section of road network and traffic data was collected on them. The intersections are simulated by the assignment of intersection capacity analysis (ICA) method. During analysis of traffic parameters, the actual values of saturation flow rate are quite different from the base model value, which results in different capacities of all nodes. Comparisons have been made between the travel times at zones, links, and nodes' levels while each comparison demonstrates a huge difference in actual traffic survey data model and base model. It has been concluded from the analysis that Budapest base transport model is very far from reality.

Authors: Kos Marjanca , Jerman Janez
Published: September 2021

This research examined the ways in which children observe flowering plants, namely: which features they perceive as significant, whether the skill of observing flowering plants develops with age, and what is the difference between genders. The research involved 174 children: 89 children aged 5 and 85 children aged 10 who were given the task of choosing the plant they recognised as the same as each of the 10 given test plants among a total of 37 plants which looked more or less similar to the test plants. The analysis of the plant combinations the children most frequently mismatched showed, that colour is the feature to which they attribute the most importance. Shape turned out to be considered more important to the children than size. Older children revealed better plant observation skills than younger ones with the girls achieving better results than the boys in both age groups. The findings show that children's observation skills develop with age, and corroborate the need to support the development of observation in the educational process.
Keywords: biology education, observation skills, plant characteristics, preschool children, primary school children.

Authors: Aslan Efe Hülya
Published: September 2021

The rapid increase in the use of Web 2.0 technologies has led to changes in school curricula because they are a powerful tool for developing innovative ways of teaching and learning. These technologies have also changed how teacher education programmes prepare pre-service teachers. Thus, as a predictor, pre-service teachers’ self-efficacy is important for the development of their computer skills. A descriptive research design was employed. The data were collected using a Web 2.0 technologies educational usage scale and a computer-related self-efficacy perception scale. The sample of the study involved 146 (F: 70, M: 76) student teachers in a teacher education course at Ziya Gökalp Education Faculty of Dicle University during the 2011-2012 academic year. The data were analysed using means, t-tests, and one-way ANOVAs. The study revealed that student teachers used Facebook the most frequently to communicate, access class material, hold discussions and form academic groups. Student teachers with Internet access at home used Web2.0 technologies more frequently than those without Internet access at home. The frequent use of Web 2.0 by student teachers provides teachers with the possibility for more student-centred learning activities in the classroom.

FACEBOOK AS A NEW COMMUNITY OF INQUIRY ENVIRONMENT: AN INVESTIGATION IN TERMS OF ACADEMIC ACHIEVEMENT AND MOTIVATION
Authors: Öztürk Ebru
Published: September 2021

The study attempts to determine whether or not Facebook is an environment suiting the Community of Inquiry Framework by investigating the cognitive, social, and teaching presence perceptions of students in Facebook groups and to examine the impact of group size on the CoI model. Additionally, whether or not these three types of presences predicted academic success and motivation were investigated. The data were analyzed through logistic regression analysis, independent samples t-test and the Pearson correlation coefficient. The study was conducted in a blended course, where Facebook was utilized for online discussions. The study revealed that the relation between cognitive, social, and teaching presences was significant and at a high-level. The high correlation determined among the social, cognitive, and teaching presence perceptions of students in learning communities created on Facebook leads to the consideration that Facebook is a suitable online environment for the COI framework. It is understandable, that all presence perceptions are higher in smaller groups when group impacts are investigated. Other conclusions derived from the study are that academic success was only predicted by cognitive presence and motivation was predicted by both cognitive and teaching presences.
Key words: academic success, cognitive presence, Facebook, motivation, social presence, teaching presence.

This study examines pre-service teachers’ beliefs about the images of a science teacher and the science teaching. Besides, how their beliefs are affected from inquiry-based teaching is investigated. Case study method was used. Pre-service teachers had learned science with inquiry and how they teach science with inquiry in the science laboratory. Data were collected through the drawings and semi-structured interviews. Results indicate that most participants had teacher-centered and conceptual belief about the images of a science teacher and the science teaching at the beginning of the study. However, they had student-centered belief at the end of the study. It was remarked that three pre-service teachers who held different beliefs about student/teacher roles and the teaching of science before the study, had some common beliefs after the inquiry-based science laboratory. Based on the results, it can be said that inquiry-based science teaching positively affects pre-service teachers’ beliefs about the images of a science teacher and the science teaching.
Key words: belief about teaching, inquiry-based teaching, mental image, pre-service teachers’ education.

ABSTRACT

This study aims to Analyze misconceptions about biological material from Integrated Science subjects at SMP N 3 Kupang City in the 2018/2019 academic year. The research method used is a qualitative method with a descriptive research design. Data collection to identify and describe misconceptions among students is done by using multiple-choice questions based on diagnostic test techniques that are equipped with Certainty of Response Index (CRI) and interviews. To analyze qualitative data in this study using the formula p = f / n × 100 to find out the percentage of students who experience understanding concepts, misconceptions and not understanding concepts. The data is then reduced, presented, and given a conclusion.Lessons are taken to identify students' misconceptions namely the respiratory system in humans. The test instrument consisted of 10 multiple choice questions and 5 question items that were given to analyze students' misconceptions. Cognitive development of students is very influential on the pattern of understanding of students themselves. This is indicated by the large percentage of students experiencing misconceptions that occur in the realm of application (C3), namely in question no. 7 with total misconceptions reaching 70.97% followed by a question no. 6 with a total of 54.83% and questions number 8 with a total of 45.16%, followed by the realm of understanding (C2) ie in question no. 3 with a percentage of 41.93% and the lowest percentage is in the realm of knowledge (C1) in question no. 15 with a percentage of 19.35%. Misconceptions experienced by students due to students' understanding patterns also vary due to several factors, namely internal factors in the form of student conditions and external, namely the teacher.

ABSTRACT

Seagress ecosystem is one of the shallow marine ecosystem that has an important role in the life of marine and is one of the most productive marine ecosystem, so that it can support the high potential of high resources as well. The ecological function of seagress ecosystem is as a producer, nutrient recycler, substrat stabilizer, sedimen capture, food and shelter of other organisme. The purpose of the research was to identifi the pigment and determine the pigment content in Enhalus acoroides (Linnaeus f.) seagress in Amadoke waters beach Akle of village, South Semau.The  research use survey method, thin layer chromotographic and spectrophotometer methods. This seagress contains pigment, seen in the result of spectrophotometric analysis in total seagress extract and pigment separation through thin layer chromotography test. In the pisment used acetone for steaming and soaking. The spectrophotometric test for the content of chrolophyll a (λ 645 nm), chrolophyll b (λ 664 nm) and carotenoid (λ 470 nm), respectivelly are 226,85 µg/mL, 368,69 µg/mL and 2923,70 µg/mL. Nine pigments found based on the Rf valuef of TLC analisis are chrolophyll a (Rf 0,78, 0,84, 0,08), chrolophyll b (Rf 0,04), chrolophyll c (Rf 0,12), feofitin (Rf 0,22 dan 0,88) and carotenoid (Rf 1,00)
