<p>This study aimed to examine the magnetic properties of sediments from Teluk Katurai Siberut island Mentawai islands. The study on sediment samples from Teluk Katurai had been carried out by using three methods, i.e., measurements of AMS (Anisotropy of Magnetic Susceptibility) to determine the anisotropy shape of magnetic susceptibility, IRM (Isothermal Remanent Magnetization) to identify the their magnetic minerals contains based on the saturation curve, and AAS (Anisotropy of Anhysteretic Susceptibility) that produce anhisteritik susceptibility. From the stereonet plot and other anisotropy parameters were obtained that ellipsoid susceptibility form is oblate. It was also obtained that the type of magnetic mineral is magnetite based on magnetic saturation curves. Meanwhile the identification of grain size distribution was obtained by plotting the value of AMS versus AAS. The plots showed the magnetic grains of sediment was approximately 0.2 µm to 0.1µm.</p><span>Key words: magnetic susceptibility, anisotropy, anhisteritic susceptibility</span>

The aims of debating are to enable the students to be active and creative in the classroom. Debating is also assumed as a valuable learning activity for teaching critical thinking and improving communication skills. Debating is an effective pedagogical way because of the level of responsibility for learning and active involvement required by all student debaters. Many teachers realize that the best strategy for motivating the students to communicate in English is by changing the situation in the class. By creating an interesting and motivating environment, the students are expected to be immersed in the activities given by the teachers. Moreover, an ideal teacher should provide opportunities for students to talk by using group work or pair work, and limiting teacher talk. Therefore, the teacher should keep encouraging the students to get involved during the process of learning in the class most of the time.</em></p></div>

The dependent variable was GPA that reflects the students’ learning outcome. The GPA data were categorized into “fail” (GPA<2.75), and “successful” (GPA≥2.75) that analyzed by using logistic regression and loglinear model. The respondents of this research were 339 students from Math, Physic and Biology Departmen who registered in 2008 - 2010 academic year. The logistic regression analysis showed that there were 3 factors that influence the students’ learning outcome significantly; their village, UN mean score and major in high school. The data analysis indicated that the students graduated from Islamic High School had a bigger chance to succes than students from Vocational School. UN mean score also can reflect the academic ability of the student significantly and the approriate major in high school (Science Studies) gave contribution to the students’ comprehension. By using loglinear analysis, it is gotten that association effect/ interaction between dependent variable and other variables as controller. The significant variable interaction was the second interaction between the school and the major chosen, while the third interaction has between UN mean score, major, and the school.</p><p style="margin: 1em 0px; color: #111111; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 11.2px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #fafafa;"> </p><span style="color: #111111; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 11.2px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #fafafa; display: inline !important; float: none;">Keywords: students learning outcome, logistic regression, probability, loglinear models</span>
