Abstract. We used task-switching (TS) paradigms to study how cognitive training can compensate age-related cognitive decline. Thirty-nine young (age span: 18–25 years) and 40 older (age span: 60–75 years) women were assigned to training and control groups. The training group received 8 one-hour long cognitive training sessions in which the difficulty level of TS was individually adjusted. The other half of the sample did not receive any intervention. The reference task was an informatively cued TS paradigm with nogo stimuli. Performance was measured on reference, near-transfer, and far-transfer tasks by behavioral indicators and event-related potentials (ERPs) before training, 1 month after pretraining, and in case of older adults, 1 year later. The results showed that young adults had better pretraining performance. The reference task was too difficult for older adults to form appropriate representations as indicated by the behavioral data and the lack of P3b components. But after training older adults reached the level of performance of young participants, and accordingly, P3b emerged after both the cue and the target. Training gain was observed also in near-transfer tasks, and partly in far-transfer tasks; working memory and executive functions did not improve, but we found improvement in alerting and orienting networks, and in the execution of variants of TS paradigms. Behavioral and ERP changes remained preserved even after 1 year. These findings suggest that with an appropriate training procedure older adults can reach the level of performance seen in young adults and these changes persist for a long period. The training also affects the unpracticed tasks, but the transfer depends on the extent of task similarities.

A Value

One indicator of the success ofeducation in the level of classroom learning is when a lecturer is able to build student learning achievement and will be more successful if this achievement can be increased if their attendance is above 80% (minimum 10 times attendance from 12 meetings). If the students can be grown discipline and provided a decent campus facilities, then as difficult as any lecture material or learning process that followed by they undoubtedly will live with feelings of joy, even they will feel sad if that day lecturer could not come because there is a need outside campus.There are four stages of appraisal that apply to each student for each course taken include (1) attendance of 10% (2) Task 20% (3) 30% Semester Exam (UTS) and (4) Final Exam Semester. (UAS) 40%. The writer as a lecturer tries to cultivate motivation to learn from the beginning, in addition to always communicate actively with students who follow the lecture also monitor attendance and assignment, each completed college is always given the practice / tasks are directly given the value, usually given the task quite easily so they can get a value of 100, even if there is a miscalculation, they are still given the opportunity to fix the error so that eventually get a value of 100. With the value of this 100, their motivation to grow and even grow in such a way that spur them to diligent lectures.The difficulty level of the task is balanced with the lecture, the longer it is raised so as to reach the maximum average level of student ability at the end of the lecture meeting...This research reveals that there is no a significant correlation between student achievement to discipline presence of student/mahasiswa with campus facilities. The analyzing was taken from an answer of 55 students who were randomly selected as respondents by filling out the Questionaire that was distributed to them. Key words : achievement, attendance, discipline, campus facility

The purpose of this research was to know how characteristic items of Try Out National Exam Year 2010/2011 at Senior High School on Mathematics Subject in Mataram City that analyzed by using Iteman Program. The characteristic in question was whether the item can be used or not based on the difficulty level of the item, the difference in power, and the functioning of the answer option. The research method used was descriptive. Techniques of collecting data in the form of documents. Source of data in the form of answer sheet of computer package 61 of Try Out National Exam Year 2010/2011 at Senior High School on Mathematics Subject in Mataram City. Aspects analyzed by using this Iteman Program include the level of difficulty item, different power, and the function of whether or not the answer choice. Based on the results of Item of Analysis Try Out National Examination of School Year 2010/2011 Senior High School on Mathematics Subjects in Mataram City by using Iteman Program, it can be concluded that for the level of difficulty Package 61 was classified. Different power for package 61 has a good category. For the reliability of having a high category and a matter of Try Out Package 61 there are 23 problems received with the improvement of 4, 5, 8, 9, 14, 16, 17, 18, 19, 20, 21, 22, 23, 24, 26, 28, 30, 31, 32, 34, 35, 36, and 40.

<p class="p1"><span class="s1">This study aims to develop a Three-tier Diagnostic Instrument on Chemical Equilibrium (TT-DICE) to diagnose high school students’ misconceptions related to this topic. TT-DICE consists of thirty items, asking for students’ answers, reasonings, and levels of confidence. Three-stages development models developed by Treagust applied in developing TT-DICE. First-stage was a literature study to analyze the main concepts and students’ misconceptions in CE. The next step is the development of the TT-DICE prototype, consisting of item development, preliminary experiments, interviews, and revisions. The third stage of validity checking starts with content validation by experts and practitioners. A field test conducted to determine the reliability and quality variables are supporting TT-DICE items. These variables are Item Validity (IV), Difficulty Level (DL), Discrimination Index (DI), and effectiveness of distractors. Content validity by validators showed that the TT-DICE is valid with a very high category (96.1%). The results of item validity show that 88.9% of the items are valid. Testing of DL, DI, and the effectiveness of distractors in general, shows a good category. The Reliability of the three-tiers TTDICE using Alpha Cronbach is a high and very high category, respectively (0.83, 0.81 &amp; 0.91). The overall validity test results also concluded if the TT-DICE is valid, reliable, and suitable to diagnose misconceptions of Chemical Equilibrium.</span></p>
