Drawing Skills

Major changes in the organisation of the teaching process at universities in Poland had to be introduced in response to the current pandemic situation and threat of further spread of SARS-CoV-2 virus. This article presents the results of the research conducted at the Faculty of Architecture, Poznan University of Technology in view of the pilot, experimental entrance exam that excludes the evaluation of drawing skills of candidates for architectural studies in the 2020/21 recruitment process. The purpose of the research was to find a correlation between the quality of candidates accepted for the BSc (engineer) programme studies, evaluated on the basis of their drawing skills demonstrated during the entrance exam and the learning outcomes of graduates. For that purpose, the authors hereof have carried out an analysis with the use of the Spearman Rank Correlation formula. The comparative analysis has shown that candidates whose drawing skills were evaluated highly during the entrance exam did not necessarily rank as the top grade scoring graduates of the first degree study programme, and thus, it has further been shown that good drawing skills at the beginning of the study programme do not guarantee top learning results at the end of the studies. In effect, the research should become a starting point for a discussion in Poland on whether there are any justified grounds for entrance exams in drawing or whether a portfolio of works may replace it and be an effective recruitment criterion.

Abstractlearning process  good teaching  can create a situation that allows children to learn, so that is the starting point of the success of teaching. The low quality of education depends on the management of the teaching and learning process which can be interpreted as being less effective in the teaching and learning process, the causes: (1) Low learning activities, (2) Inadequate facilities and infrastructure. The case in Solok City Middle School, the low level of student learning activities allegedly influenced the low student learning outcomes. Based on observations on class VIII A which included the superior class had not yet achieved the desired completeness, the class with the least completeness was class VIII B which was 33.33% with KKM 65 criteria. Seeing this reality, teachers were required to motivate students and foster enthusiasm student learning. Therefore, to foster students' enthusiasm for learning, the author tries to apply student learning activities through discussion methods in small groups.Keywords: Learning, discussion AbstrakProses belajar mengajar yang baik dapat menciptakan situasi yang mmemungkinkan anak belajar, sehingga merupakan titik awal keberhasilan pengajaran. Rendahnya mutu pendidikan tergantung pada pengelolaan proses belajar mengajar yang dapat diartikan kurang efektifnya proses belajar mengajar, penyebabnya: (1) Rendahnya aktifitas belajar,  (2) Sarana dan prasarana yang belum memadai. Kasus pada SMP Negeri % Kota Solok rendahnya aktifitas belajar siswa diduga berpengaruh terhadap rendahnya hasil belajar siswa. Berdasarkan pengamatanpada  kelas VIII A yang termasuk kelas unggul belum mencapai ketuntasan yang di inginkan, sedangkan kelas yang paling sedikit ketuntasannya adalah kelas VIII B yaitu sebanyak 33,33 % dengan kriterian KKM 65. Melihat kenyataan tersebut, guru dituntut untuk dapat memotivasi siswa dan menumbuhkan semangat belajar siswa. Karena itu, untuk menumbuhkan semangat belajar siswa, penulis mencoba untuk menerapkan aktivitas belajar siswa melalui metode diskusi dalam kelompok kecil. Kata kunci: Pembelajaran, diskusi

The use of digital multiple-choice tests in formative and summative assessment has many advantages. Such tests are effective, objective, and flexible. However, it is still challenging to create tests that are valid and reliable. Bloom’s taxonomy is used as a framework for assessment in higher education and therefore has a great deal of influence on how the learning outcomes are formulated. Using digital tools to create tests has been common for some time, yet the tests are still mostly answered on paper. Our hypothesis has two parts: first, it is possible to create summative tests that match different levels and learning outcomes within a chosen subject; second, a test tool of some kind is necessary to enable teachers and examiners to take a more proactive attitude to(wards) different levels and learning outcomes in a subject and so ensure the quality of digital test designing. Based on an analysis of several digital tests we examine to what degree learning outcomes and levels are reflected in the different test questions. We also suggest functionality for a future test tool to support an improved design process.

Quality Of Learning

A change in teaching delivery at a large Australian university, from two semesters to three trimesters, was the occasion for using more formative assessment in a core first-year mathematics unit. This study compared evidence about learning outcomes for two cohorts in adjacent years. Cohort 1 was the last taught over a semester, and Cohort 2 the first taught over a trimester. There was no change in overall workload, and no change in the unit's total teaching hours, syllabus or materials. Assessments were changed for class tests during the teaching period by giving Cohort 2 access to unlimited practice and computer-assisted feedback on the questions in the test database, followed by doing the tests under examination conditions. For Cohort 2, a written assignment was also added, focused on giving a clear solution to a mathematics problem, and awareness of the need for appropriate evidence, both background and internal to the problem. Learning outcomes were compared using closely comparable tasks from the final examinations, and examining students' answers in the examination scripts. Outcomes were assessed by a method derived from the solo taxonomy, which afforded a common scale to measure the quality of learning outcomes observable in final examination scripts. Results on separate tasks, plus those for a composite score, favoured Cohort 2. The effect size for the composite score was 0.457. This indicates that the unlimited practice with computer feedback for class tests, and the writing assignment, were functioning as intended in promoting learning with understanding. References S.

In Vietnam, since 2015, the Ministry of Education and Training of Vietnam has decided to abolish university entrance exams and advocates the use of high school graduation exam results of candidates for admission to go to universities. The 2015 and 2016 exam questions for the Math exam are the essay questions. From 2017 up to now, the Ministry of Education and Training of Vietnam has applied the form of multiple-choice exams for Mathematics in the high school graduation exam. There are many mixed opinions about the impact of this form of examination and admission on the quality of university students. In particular, the switch from the form of essay examination to multiple-choice exams led the entire Vietnam Mathematical Association at that time to send recommendations on continuing to maintain the form of essay examination for mathematics. The purposes of this article are analysis and evaluation the effects of relevant factors on the academic performance of advanced math students of university students, and offer solutions to optimize university entrance exam. The data set was provided by Training Management Department and Training Quality Control and Testing Laboratory of the University of Finance – Marketing. This dataset includes information about math high school graduation test scores, learning process scores (scores assessed by direct instructors), and advanced math course end test scores of 2834 students in courses from 2015 to 2019. Linear and non-linear regression machine learning models were used to solve the tasks given in this article. An analysis of the data was conducted to reveal the advantages and disadvantages of the change in university enrollment of the Vietnamese Ministry of Education and Training. Tools from the Python libraries have been supported and used effectively in the process of solving problems. Through building and surveying the model, there are suggestions and solutions to problems in enrollment and input quality assurance. Specifically, in the preparation of entrance exams, the entrance exam questions should not exceed 61-66 % of multiple choice questions.

ABSTRACT An important factor for the success of a CSR program is effective communication. Communication will be effective if it has an impact. If the information is conveyed based on the needs, then the communication will be effective. This study aims to analyze the factors which are related to the effectiveness of CSR communication. This study used a census method to approach 37 participants who received CSR programs. The Data analysis used the Spearman rank correlation for the statistical tests. The results showed that there was a correlation between factors that have the strength of CSR companion communication (level of attractiveness of the companion, quality of message content, and sources of information) which have real communication at the level of understanding of the participants of the Kertajaya Creative Destination (KCD) CSR program. In addition, there is a real correlation the factors that have the strength of CSR companion communication (the level of credibility of the companion, the source information, and the level of the recipient) and having communication at the level of attitudes of participants in the Kertajaya Creative Destination (KCD) CSR program. However, there is no real correlation between CSR companion communication factors and participant actions.Keywords :communication effectiveness, CSR, elements of communication. ABSTRAK Faktor penting dari keberhasilan program CSR adalah komunikasi yang efektif.

A great number of cheese dairies and dairy industries in Greece are disposing their wastes, mainly cheese whey, either on land or in surface receivers, in large quantities creating a major environmental problem. A typical agricultural and pastoral provincial town of 70,000 inhabitants, Trikala, became the starting point of this research. A co-treatment of the urban sewage and the dairy wastes in the municipal treatment plant was recommended. The successful application of the above statement is based primarily on the pretreatment of the cheese dairies wastes. So far for cheese whey the recovery of the lactose serum in the contemporary central unit applying membrane technology has been suggested. As far as the wastewaters of the washing and refrigeration are concerned a pretreatment is required for the defatting in a grease trap, the grating, the adjustment of pH and the equalisation in an appropriate tank. Finally, this research has also focussed on the importance of membrane technology in improving the quality of milk and cheese production.
