The research was carried out the lock of student’s abilities in understanding time unit. Time unit is abstract, so it’is needed real object as a model to make the student understand easily.in other hand, the student should be given real activity that can be recreved easily. In order to make them understand the concept of time unit.The success of a teaching and learning process is one of the reasons due to the use of media or participation in the teaching and learning process. Because in the teaching and learning process media has an important meaning.This research used a qualitative method, and used  wall clock that made by paper carton. With a wall clock made of cardboard, it is easy for students to use the clock by rotating the direction of the needle on the cardboard between the long needle and the short needle must match.

Mobile devices and social media have been used to create empowering healthcare services. However, privacy and security concerns remain. Furthermore, the integration of interoperability biomedical standards is a strategic feature. Thus, the objective of this paper is to build enhanced healthcare services by merging all these components. Methodologically, the current mobile health telemonitoring architectures and their limitations are described, leading to the identification of new potentialities for a novel architecture. As a result, a standardized, secure/private, social-media-based mobile health architecture has been proposed and discussed. Additionally, a technical proof-of-concept (two Android applications) has been developed by selecting a social media (Twitter), a security envelope (open Pretty Good Privacy (openPGP)), a standard (Health Level 7 (HL7)) and an information-embedding algorithm (modifying the transparency channel, with two versions). The tests performed included a small-scale and a boundary scenario. For the former, two sizes of images were tested; for the latter, the two versions of the embedding algorithm were tested. The results show that the system is fast enough (less than 1 s) for most mHealth telemonitoring services. The architecture provides users with friendly (images shared via social media), straightforward (fast and inexpensive), secure/private and interoperable mHealth services.
