Communicative Abilities

This descriptive qualitative study aims to describe the metacognitive and communicative abilities of the third-semester students of Mathematics Education of UIN Sunan Ampel Surabaya. Forty students were given a test consists of 2 essay problems of number theory. Three of the answer sheets that each one representing students with high, medium, and low scores were analyzed. Findings show that the students' ability in both aspect are unsatisfactory regardless of their different scores. They are don't show their understanding of the concepts and principles of number theories, some of them still use mathematical terms and notes, and the majority still have the wrong calculation because they not use the complete and correct algorithm. The students' ability in mathematical communication is poor because they can't write the correct mathematical symbols and can't put the mathematical ideas in an acceptable, logical order. They have written the answers that seem to the right answers, but the arrangement of the answers is irrational and jumping, resulting in the answers in low comprehensibility.

Mathematical communication skill is very important for university students because through communication, students can convey their mathematical ideas, knowledge and arguments. However, the facts show that the written mathematical communication skills of students majoring in Mathematics Education at IAIN Tulungagung are classified as low. The low written mathematical communication skill of students is indicated by errors in writing mathematical symbols on an equation and unsystematic writing of the steps to solve mathematical problems. This study aimed to determine the effectiveness of the Think Pair Share (TPS) learning model using Google Classroom media to improve the written mathematical communication skill of IAIN Tulungagung students. Several previous researchers have reviewed the use of Google Classroom in learning, but it was not integrated with the TPS learning model and did not focus on the influence on students' mathematical communication skill. The study sample was 40 students of the 5th semester in 2019/2020 academic year majoring in Mathematics Education at IAIN Tulungagung who took the Differential Equation course. The data collection was carried out by providing a pretest and posttest before and after implementing the learning using the TPS model with Google Classroom media. Then, the data from the pretest and posttest results were analyzed using the Wilcoxon test because the data were not normally distributed. The results of this study showed that the TPS learning model using Google Classroom media could improve the students' mathematical communication skill.

A 55-year-old woman was referred because of diffuse pruritic erythematous lesions and an ischemic process of the third finger of her right hand. She was known to have anaemia secondary to hypermenorrhea. She presented six months before admission with a cutaneous infiltration on the left cubital cavity after a paravenous leakage of intravenous iron substitution. She then reported a progressive pruritic erythematous swelling of her left arm and lower extremities and trunk. Skin biopsy of a lesion on the right leg revealed a fibrillar, small-vessel vasculitis containing many eosinophils.Two months later she reported Raynaud symptoms in both hands, with a persistent violaceous coloration of the skin and cold sensation of her third digit of the right hand. A round 1.5 cm well-delimited swelling on the medial site of the left elbow was noted. The third digit of her right hand was cold and of violet colour. Eosinophilia (19 % of total leucocytes) was present. Doppler-duplex arterial examination of the upper extremities showed an occlusion of the cubital artery down to the palmar arcade on the right arm. Selective angiography of the right subclavian and brachial arteries showed diffuse alteration of the blood flow in the cubital artery and hand, with fine collateral circulation in the carpal region. Neither secondary causes of hypereosinophilia nor a myeloproliferative process was found. Considering the skin biopsy results and having excluded other causes of eosinophilia, we assumed the diagnosis of an eosinophilic vasculitis. Treatment with tacrolimus and high dose steroids was started, the latter tapered within 12 months and then stopped, but a dramatic flare-up of the vasculitis with Raynaud phenomenon occurred. A new immunosupressive approach with steroids and methotrexate was then introduced. This case of aggressive eosinophilic vasculitis is difficult to classify into the usual forms of vasculitis and constitutes a therapeutic challenge given the resistance to current immunosuppressive regimens.

Choice of profession is a social phenomenon that every person has to face in life. Numerous studies convince us that not only the well-being of a person depends on the chosen work, but also his attitude to himself and life in general, therefore, the right and timely professional choice is very important. Research about factors of career self-determination of students of higher education institutions in Ukraine shows that self-determination is an important factor in the socialization of young person, and the factors that determine students' career choices become an actual problem of nowadays. The present study involved full-time and part-time students of Institute of Philology and Mass Communications of Open International University of Human Development "Ukraine" in order to examine the factors of career self-determination of students of higher education institutions (N=189). Diagnostic factors of career self-determination of students studying in the third and fourth year were carried out using the author's questionnaire. Processing of obtained data was carried out using the Excel 2010 program; factorial and comparative analysis were applied. Results of the study showed that initial stage of career self-determination falls down on the third and fourth studying year at the university, when an image of future career and career orientations begin to form. At the same time, the content of career self-determination in this period is contradictory and uncertain, therefore, the implementation of pedagogical support of this process among students is effective.

ABSTRACT Parental perception will affect the fulfillment of children’s participation rights. Fullfilment of children’s participation rights will be fulfilled optimally if parents pay anttention to opinions while providing opportunities for children to make and make decisions about the child’s goals and self-interest. The subjects studied consisted of 5 subjects consisting of father and mother who had children aged 9- 12 years. This study uses qualitative research methods, with data retrieval tools in teh form of interviews, observation and documentation. From the research found data were the subjects do not fulfill the right of participation of children up to the maximum ladder where children’s participation rights range from the first ladder to the third ladder. The first ladder to the third ladder is actually a non- participating ladder. This means that children is manipulated, dominated by parents, there is direct communation and the severity of the parent. The children felt disappointed, sad, and angry with the parents but they still tried to hear and obey the parent’s decision. Children from third and fourth subjects experienced excessive fear to speak to their parent (father). Suggestions for parents to be more caring and fulfill the rights of children’s participation so as not to affect the growth and development of children.
