Teaching Remotely: Educating Radiology Trainees at the Workstation in the COVID-19 Era. Virtual Learning During the COVID-19 Pandemic. Almarzooq Zaid I., Lopes Mathew, Kochar Ajar. Validation of the Social Provision Scale with Indonesian Student Sample: A Rasch Model Approach. Knowledge of measuring the validity and reliability of a test instrument is needed by the teacher to improve students’ quality of the test instrument. At the same time, the MNSQ outfit values range between 0.80 and 3.35. It was obtained that the MNSQ infit value was between 0.83 and 1.29. The construct validity was analyzed based on the correlation of person measure and outfit and MNSQ infit. Of these three things, the consistency of student answers is weak, the interaction between students and the overall question items is sufficient, and the quality of the items is good. This software’s output statistical summary produces person reliability=0.55, Cronbach Alpha 0.63, and reliability items of 0.91. Respondents were 67 students of grade 11 for mathematics as many as 25 questions with a choice of answers. In this article, measuring the mathematical test instrument’s validity and reliability used Rasch modeling with Winteps software. It is beneficial for the preparation of a better test instrument. The validity and reliability of the mathematics subject test instrument applied to ThatQuiz need to be known. Take online exams for all subjects at Lab High School using the application ThatQuiz. Mathematics learning, which has been difficult for the average high school student, is also conducted online.

Likewise, the performance of learning at SMA Lab UM is carried out online.

Using TI products outside limits stated in TI's official published Specifications may void TI's warranty. Customers are solely responsible to conduct sufficient engineering and additional qualification testing to determine whether a device is suitable for use in their applications. THIS INFORMATION IS PROVIDED 'AS IS.' It could change without notice. X-ray exposures over these limits, however, may cause damage to the device and should be avoided. Experience has shown that most TI products will NOT be sensitive to typical x-ray inspection (with typical exposures < 100 rad(Si)). TI does not typically specify acceptable x-ray levels on the device datasheet. All TI products undergo qualification and reliability testing or qualification by similarity justification prior to release. The qualification process is how we confirm that the reliability of our designs, processes, products and packages meets industry standards.
