Students' communication skills need to be described because they are used as communication tools in solving problems given. This study aims to find out and analyze students' mathematical communication skills and their obstacles to the topic of two-variable linear equation systems. This type of research is descriptive research. The research subjects consisted of 6 students divided in high, medium and low-ability students who were selected from 20 students, class VIII students of Riau Global IT Middle School Pekanbaru in 2018/2019. The method used is tests and interviews. The results obtained by the overall achievement were 70% of the achievement of indicators expressing mathematical ideas by speaking, writing, showing, and describing them visually, 66.7% for indicators of understanding, interpreting, and evaluating mathematical ideas presented in the form written, oral, or visual and 40% for the achievement of indicators using vocabulary, notation, and mathematical structures to represent ideas, describe relationships, and model situations. Whereas the obstacles to mathematical communication skills found are the ability of prerequisites that are not fulfilled, low reading and writing skills and low mathematical understanding of students.

Research  background  and  hypothesis.  Previous  research  has  proved  that  children  engaged  in  sports  easier integrate into the society and their psychological well-being is much higher,  sports activities can help them resist to the harmful influence of their peers and prevent them from engaging into delinquent behavior. However, there still is a lack of a studies providing evidence about factors that determine the expression of compulsion. Hypothesis: The level of self-esteem and self-confidence of adolescent athletes influences the occurrence of bullying and the initiation of it.  Research  aim  was  to  disclose  the  relationship  between  the  level  of  adolescent  athletes’  self-esteem,  self-confidence and the occurrence of bullying.Research methods. The study applied I. Shostrom’s modified self-esteem scale questionnaire and the adapted Bullying Scale for Schoolchildren. Research  results.  Results  showed  a  weak  correlation  between  bullying  and  self-esteem  levels  (γ =  0.24; p > 0.05). We found a weak adverse relationship between initiating bullying and self-assessment levels (γ = –0.16; p > 0.05), weak adverse correlation between experienced bullying and self-confidence levels (γ = –0.15; p > 0.05) and a weak linear relationship between initiating bullying and self-confidence (γ = 0.20; p > 0.05).Discussion and conclusions. Contrary to what we expected, we observed that athlete adolescents with the high levels of self-esteem suffered from bullying sometimes and often. Research findings suggest that adolescents who tend to initiate bullying demonstrated moderate and low levels of self-esteem. Most of athlete adolescents admitted that that did not initiate bullying or if they did, that was done only occasionally. It was found that adolescents with high and moderate self-confidence levels experienced bullying occasionally or not at all. Some athletes with low self-confidence levels professed that they suffered from bullying more often, and they also admitted that they often initiated bullying themselves. In our research we were unable failed to provide evidence which would prove that sports activities impacted or influenced adolescents’ bullying initiatives or experiences; therefore further research is needed to determine whether self-esteem and other internal personality qualities could affect the expression of bullying among non-athlete adolescents.Keywords: aggression, adolescents’ self- assessment, self-confidence.

This research aimed to find out the English language proficiency of the local tour guides at the Aceh Tsunami Museum, Aceh, Indonesia, and the difficulties that they faced in communicating with foreign tourists in English. A quantitative and qualitative descriptive research design was utilized to collect data in which an English proficiency test and an interview were used as instruments. The research subjects were 13 local guides working in the Aceh Tsunami Museum. Based on the results from this research, it was found that virtually all the participating tour guides were in the categories of very good, good and average.  However, they still experienced problems with several aspects of speaking EFL, such as expressing ideas verbally, poor collocations i.e. incorrect or inappropriate word choices, poor pronunciation, and lack of confidence when speaking English. It is expected that the results from this research will become a useful input for the management of English Education institutions for improving their instructional systems and for tour guides to continue learning and developing their communication skills, especially their oral English communication skills.

LANGUAGE NOTE | Document text in English; abstract also in Chinese. The purpose of this study was to examine the relationships between competitive anxiety and self-confidence among collegiate varsity athletes. Participants were 96 athletes from a university in the United States, and their sport affiliations included baseball, volleyball, softball, track and field, and gymnastics. The following four questionnaires were administered to the participants: Competitive State Anxiety Inventroy-2, State Sport-Confidence Inventory, Sport Competition Anxiety Test for Adults, and Trait Sport-Confidence Inventory. Data were analyzed by Pearson product-moment correlations. Results showed that athletes who possessed a low level of competitive trait anxiety on a regular practice day tended to have low levels of cognitive state anxiety and somatic state anxiety, as well as high levels of state self-confidence and state sport­-confidence on a competition day. In addition, athletes who possessed a high level of trait sport-confidence on a regular practice day tended to have low levels of cognitive state anxiety and somatic state anxiety, and high levels of state self­-confidence and state sport-confidence on a competition day. The present investigation also found that cognitive state anxiety and somatic state anxiety were the predictors to estimate athletes’ self-confidence and performance. 本文旨在檢驗大學生運動員的競賽焦慮與自信之間的相關聯繫，研究對象為美國一所大學的九十六名大學生運動員，他們所在的運動隊包括壘球、排球、棒球、田徑和體操。四個調查問卷(其中兩個用於測量競賽焦慮，兩個用來調查運動員的自信心)被用來收集數據。並採用佩爾森運動相關係數檢驗法對數據進行了分析。結果表明:在正常訓練日裡具有低水平特質性競賽焦慮的運動員傾向於在競賽之日具有低水平的認知性焦慮和軀體性焦慮，但具有較高水平的狀態運動性自信心。而在正常的訓練日具 有高水平的特質性運動自信心的運動員傾向於在競賽之日具有低水平的認知性焦慮與軀體性焦慮。本研究也證實了認知性焦慮與軀體性焦慮為兩項預測運動員自信心與競技表現的有效指示。
