Foreign Language Anxiety and Its Impacts on Students’ Speaking Competency

Anxiety may either have negative or positive impacts on one’s learning process. It is possible that anxiety may deteriorate the quality of learning process by making the learner intellectually and psychologically disturbed. In other cases, anxiety may increase students’ learning motivation due to the feeling of pressure. This study aimed to investigate the factors that contribute to students’ foreign language anxiety and its impacts on their speaking competency. The participants are university students taking English Conversation Class. Classroom observations were done to evaluate students’ speaking performance. Other instruments were Foreign Language Class Anxiety Scale (FLCAS) questionnaire and interviews. The results showed that the students had slightly high anxiety level; and there was an invert relationship between the anxiety level and the speaking scores. Several major factors that cause anxiety among the students have been identified, and it was also seen that anxiety has its most negative impacts on students’ communicative and interactive ability

The aim of this study was to describe: (1) the interaction between cooperative model learning and achievement motivation towards mathematics achievement, (2) the differences between students\u27 mathematics achievement who learned through Cooperative Learning Type GI and STAD, (3) the differences between students\u27 mathematics achievement who learned through cooperative Learning Model Type GI and STAD on students with high achievement motivation, (4) the differences between students\u27 mathematics achievement who learned through cooperative Learning Model Type GI and STAD on students with low achievement motivation. The conclusions of this study were: (1) there is an interaction between cooperative learning model and achievement motivation towards students\u27 mathematics achievement; (2) the cooperative learning model of GI type give lower mathematics achievement than cooperative learning model of STAD type; (3) on students with higher achievement motivation, the cooperative learning model of GI type gives mathematics achievement is higher than STAD type.Tujuan penelitian ini untuk menjelaskan: 1) ada tidaknya interaksi antara model pembelajaran kooperatif dan motif berprestasi siswa dengan prestasi belajar matematika, 2) perbedaan prestasi belajar matematika antara siswa yang dibelajarkan menggunakan model pembelajaran kooperatif tipe GI dan STAD, 3) perbedaan prestasi belajar matematika antara siswa yang dibelajarkan menggunakan model pembelajaran kooperatif tipe GI dan STAD pada kelompok siswa dengan motif berprestasi tinggi, 4) perbedaan prestasi belajar matematika antara siswa yang dibelajarkan menggunakan model pembelajaran kooperatif tipe GI dan STAD pada kelompok siswa dengan motif berprestasi rendah. Kesimpulan penelitian adalah : (1) ada interaksi antara pembelajaran kooperatif dan motif berprestasi dengan prestasi belajar matematika; (2) prestasi belajar matematika dengan model pembelajaran kooperatif tipe GI lebih rendah atau sama dengan STAD; (3) pada siswa dengan motif berprestasi tinggi prestasi belajar matematika dengan model pembelajaran kooperatif tipe GI lebih tinggi dibandingkan

SPATIAL PRICING EFFICIENCY: THE CASE OF U.S. LONG GRAIN RICE

The spatial rice price relationships for U.S. long grain rough rice are affected by many factors besides the transportation cost between markets, such as milling, processing, cooking and nutritional value as well as physical characteristics. This study applies a time series framework to analyze long run price relationships for Arkansas, Mississippi, Louisiana, Texas and California long grain rice. Johansen's test results showed that at least there are two cointegrating price vectors. However, such a finding is not supported by the ECM model in any of the price series.Demand and Price Analysis,

Pengaruh Jenis Paduan Mikro Fe-cr Hasil Metode Ultrasonik Pada Pembentukan Bongkah Paduan Fe-cr Melalui Sintering Dua Tahap

PENGARUH JENIS PADUAN MIKRO Fe-Cr HASIL METODE ULTRASONIK PADA PEMBENTUKAN BONGKAH PADUAN Fe-Cr MELALUI SINTERING DUA TAHAP. Fe-Cr adalah paduan yang memiliki ketahanan pada suhu tinggi dan potensial digunakan sebagai interkonek pada sel bakar Solid Oxide Fuel Cell (SOFC). Pada penelitian ini telah dilakukan sintesis bongkah paduan Fe-Cr dengan menggunakan serbuk paduan mikro Fe-Cr hasil sintesis dengan metode ultrasonik. Metode ultrasonik dimanfaatkan untuk sintesis paduan mikro Fe-Cr melalui penggunaan gelombang suara ultrasonik. Langkah yang dilakukan adalah konsolidasi partikel paduan mikro Fe-Cr melalui kompaksi tanpa lubrikan, kemudian dalam kapsul kaca kuarsa dilakukan proses sintering sampai 1000 oC selama 1 jam, lalu dilanjutkan sintering hingga 1300 oC selama 2 jam, lalu didinginkan dalam tungku. Karakterisasi struktur mikro dilakukan dengan Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (SEM-EDS), X-Ray Diffraction (XRD) disertai analisis dengan metode Rietveld dan pengukuran densitas sesungguhnya. Partikel paduan mikro Fe-Cr seutuhnya lebih stabil dan konsisten dalam pembentukan fasa bongkah paduan Fe-Cr melalui sintering bertahap. Diperoleh bongkah paduan Fe-Cr homogen tanpa oksida

The Influence of Grain Refiner on Dendrite Arm Spacing of Aluminum Alloy Adc 12

THE INFLUENCE OF GRAIN REFINER ON DENDRITE ARM SPACING OF ALUMINUM ALLOY ADC 12. ADC 12 is the common used materials for die casting process in producing automotive components. Grain refiner was added to aluminum ADC 12 to increase mechanical properties by decreasing grain size and improving fine distribution of gas porosity. Grain refiner also give positive effect in aluminum fluidity, where the proper addition of grain refiner will increase the fluidity. The purpose of present research is determining correlation between grain refiner addition and dendrite arm spacing, which also indirectly related to the grain size. 100% scrap of aluminum ADC12 and Al5Ti1B grain refiner were used as raw materials. Melting process has been done in a 1400 gr crucible with cokes and oxygen as the fuming energy. Argon was introduced into crucible at least in 1 minute for degassing. After degassing process accomplished, 0, 0.05, 0.1, 0.15, 0.2 % grain refiner Al5TiB, which have been choosen as experimental variable, were charged into crucible. Vacuum suction machine has been utilized to measure the aluminum fluidity at 680 0C, the common ADC 12 pouring temperature. Samples for microstructural analysis were tooken at the tip of specimen from vacuum suction test. Measurement of dendrite arm spacing (DAS) was conducted by SIGMA SCAN Pro.5 Software. The result indicated that at 680 0C, the addition up to 0.15% Al5Ti1B grain refinement reduced 50% dendrite arm spacing from 8.8 ìm (without grain refiner) to 4.5 ìm. Over 0.15% Al5Ti1B, the refinement stopped and DAS increased caused by the complex intermetallic phase (Ti-Al, Ti-B) has nucleated from the excess grain refiner
