Mathematics learning needs to be directed in understanding mathematical concepts and principles because it will necessary for solving problems, problems other disciplines, everyday life. But sometimes, we make mistakes both intentional unintentional so that they have an impact on the results of work on. Today many studies discuss difficulty students math but there has been no research discusses...

Appropriate warming of the periocular or posterior cervical skin has been reported to induce autonomic or mental relaxation in humans. To clarify the effects of cutaneous warming on human sleep, eight male subjects with mild sleep difficulties were asked to try three experimental conditions at home, each lasting for 5 days, in a cross-over manner: warming of the periocular skin with a warming d...

For the purpose of selecting items in a test, this study presented a viewpoint of psychologically optimal difficulty level, as well as measurement efficiency, of items. A paper-and-pencil test (P & P) composed of hard, moderate and easy subtests was administered to 298 students at a university. A computerized adaptive test (CAT) was also administered to 79 students. The items of both tests were...

Human computation games (HCGs) often suffer from low player retention. This may be due to the constraints placed on level and game design from the real-world application of the game. Previous work has suggested using player rating systems (such as Elo, Glicko-2, or TrueSkill) as a basis for matchmaking between HCG levels and players, as a means to improve difficulty balancing and thus player re...

Semantics based knowledge representations such as ontologies are found to be very useful in automatically generating meaningful factual questions. Determining the difficulty level of these system generated questions is helpful to effectively utilize them in various educational and professional applications. The existing approaches for finding the difficulty level of factual questions are very s...

In this this paper, we discuss the interest and the need to evaluate the difficulty of single player video games. We first show the importance of difficulty, drawing from semiotics to explain the link between tension-resolution cycles, and challenge with the player’s enjoyment. Then, we report related work on automatic gameplay analysis. We show through a simple experimentation that automatic v...

multiple-choice tests are the most common type of tests used to evaluate medical education.  these tests have long been used in the written format for specialized boards and residency promotion tests in iran and kermanshah university of medical sciences (kums), as well (1). multiple-choice tests are being analyzed using quanti­tative method (test level, difficulty level and discrim­ination leve...
