This study aims to implement android-based learning media in mathematics basic concepts courses on student achievement, and the effectiveness of android-based learning media in mathematics basic concepts courses on student achievement at PGMI Nurul Jadid University. This research uses a quantitative research approach. The data collection is done through documentation and tests. The determination of the sample of this research was carried out by random sampling technique which included the fourth-semester PGMI Study Program students. While the data analysis in this study uses paired sample t-test analysis techniques. Based on the results of data analysis, it can be concluded that t-count = -18,378 with significance = 0,000 < 0.01. Thus, it can be stated that H1 is accepted and H0 is rejected, so it can be concluded that the android-based learning media on the subject of mathematics basic concepts are convincingly effective in improving student achievement.

The study aimed to improve the learning activeness of fourth-grade students through the application of the Two Stay Two Stray learning model. This research design is qualitative research. The instrument of data collection uses observation of teacher and student activities and interviews. The results of the study indicate that: this learning model must form groups of 4 people. Then discuss with the group that has been determined. After discussing, two people from each group visited other groups to get information on the results of discussions from each group. While the task of two members who settled in their group must give the results of their discussion to other groups. The learning process using the learning model Two Stay Two Stray can improve the learning activeness of fourth-grade students of MIN 1 Probolinggo. By using this learning model, students become enthusiastic in learning and they are no longer passive because each individual has their respective duties, so this learning model is declared successful in increasing student learning activeness.

The rapid development of science and advances in advanced technology have implications for the rhythms of human communication. A very striking implication is that people are increasingly free and easy (easy access) in obtaining information and knowledge, including in the field of education. The global education environment is seen in several ways to provide solutions to other gaps and problems through the soaring distributed learning opportunities. Learning process activities with the help of information and communication technology take place not only applied limited by space, location or level of education such as at school or college, but can be done in many different places and involve a lot of people. Learning methods from learners that are not limited to time and place are called information and communication technology based learning. Learning media that can be used in distance learning are: computers, television, radio, internet, voice recordings, and VCD tapes.

Reçu le 24 Mars 2010; accepté le 13 Décembre 2010; la discussion concernant cet article est ouverte jusqu'au 1er Octobre 2011 Citation Bali, M. & Gueddari, M. (2011) Les chenaux de marée autour des îles de Kneiss, Tunisie: sédimentologie et évolution. Hydrol. Sci. J. 56(3), 498-506.Résumé L'Archipel de Kneiss, dans le Golfe de Gabès (sud-est Tunisien), est un milieu à originalités multiples. Il est unique en son genre en Tunisie en raison de la variété de son paysage morphologique (marais maritimes, falaises, plages sableuses et îlots qui émergent des hauts fonds). Il est caractérisé par la présence de chenaux de marée submergés. L'objectif principal de ce présent travail est de caractériser les principales composantes qui interviennent dans la dynamique sédimentaire au niveau de ces chenaux. Les résultats des analyses granulométriques et minéralogiques des sédiments de surface prélevés au niveau des chenaux de marée ont permis d'identifier l'origine de ces sédiments et de préciser les facteurs et les phénomènes qui interviennent dans leur transport et leur dépôt. Ces résultats montrent que les sables des chenaux de marée présentent un granoclassement décroissant de l'aval vers l'amont, ce qui prouve que les courants de marée ont une action plus importante lors du flot que lors du jusant. Ces résultats montrent aussi que le mode de transport est exclusivement le roulement par les courants de marée. Les minéraux argileux et non argileux des sédiments de surface auraient pour origine essentiellement les formations géologiques qui affleurent dans l'arrière-pays. L'analyse des photographies aériennes montre que les chenaux de marée présentent une évolution morphologique.

It is unique in its genre in Tunisia due to the variety of its morphological landscape (sea-board swamp, cliffs, sandy beaches and islets that emerge from high basements). It is characterized by the presence of submerged tidal channels. The main objective of this work is to characterize the components that contribute to the sedimentary dynamic at the level of those channels. The results of granolithic and mineralogical analyses of surface sediments taken at the level of the tidal channels have allowed us to identify the origin of the sediments and specify the factors and the phenomena that contribute to their transport and deposit. These results have shown that the sands of the tidal channels present a decreasing granolithic filing from the downstream to the upstream, indicating that the action of the tidal currents is more important during the flood tide than during the ebb tide. These findings also show that the mode of transport is exclusively the roll of the tidal currents. The clay and non-clay minerals of surface sediments may have originated mainly from the geological for...

This paper aims to analyze students' moral decadence problems in school. Brawls, free sex and narcotics on students is evidence of school failure in building the religious character of students. One of the educational institutions that have succeeded in building the religious character of students is pesantren. This success was proven by a little reporting of deviant behaviour among santri. By using descriptive qualitative methods, researchers want to reveal the profile of public schools that not only excellent academic achievement but are also able to produce students who have a religious culture so as to avoid various deviant behaviours. The religious culture is formed through the internalization of the values of the pesantren, namely to incorporate Islamic values through habituation manifested in school programs like a pesantren. The implication of this study is to internalize the value of pesantren in schools that can shape the religious character of students. Students can avoid bad behaviour. Abstrak Tulisan ini bertujuan untuk menelaah masalah dekadensi moral yang banyak dialami pelajar di sekolah. Tawuran, sex bebas, dan narkotika dikalangan pelajar merupakan wujud nyata kegagalan sekolah dalam membangun karakter religius siswa. Salah satu lembaga pendidikan yang dianggap berhasil membangun karakter religius siswa adalah pesantren. Keberhasilan tersebut terbukti dengan minimnya pemberitaan perilaku menyimpang dikalangan santri. Dengan menggunakan metode kualitatif deskriptif, peneliti hendak mengungkap profil sekolah umum yang tidak hanya unggul dalam prestasi akademik namun juga mampu mencetak siswa yang memiliki budaya religius sehingga terhindar dari berbagai perilaku menyimpang. Budaya religius tersebut terbentuk melalui internalisasi nilai-nilai kepesantrenan yakni menanamkan nilai-nilai Islam melalui pembiasaan yang diwujudkan dalam program-program sekolah layaknya sebuah pesantren. Implikasi dari studi ini adalah internalisasi nilai-nilai kepesantrenan di sekolah dapat membentuk karakter religius siswa sehingga dapat mencegah siswa dari perilaku menyimpang.
