Patterns of Teaching-Learning Interaction in the EFL Classroom

The successfullness of teaching-learning process is highly influenced by the patterns of interactions appeared in the classroom activities. Through this case study, the purpose of this paper is to explore the patterns of interaction during teaching and learning proccess. Two accellerated classes were observed and recorded to gain the data. The findings revealed that the patterns of interaction emerged in the first class were group work, choral responses, closed-ended teacher questioning (IRF), individual work, student initiates-teacher answers, open-ended teacher questioning, and collaboration. Meanwhile, the patterns of interaction in the second class showed closed-ended teacher questioning (IRF), open-ended teacher questioning, choral responses, student initiates-teacher answers, group work, and individual work pattern. The patterns of interaction were produced from teacher and student(s) and/or student(s) and student(s) in relation to the teacher talk and the students talk categories used during learning activities. These patterns were produced constantly. They are to show that the teaching-learning process was not always dominated by the teacher. Most students actively participate as well in any classroom activity. Thus, these patterns absolutely increase the students talk and students' participation in the class. It is necessary for teachers to reorganize the active activities which might foster more interaction in the classroom

Patterns theory and geodesic automatic structure for a class of groups

We introduce a theory of "patterns" in order to study geodesics in a certain class of group presentations. Using patterns we show that there does not exist a geodesic automatic structure for certain group presentations, and that certain group presentations are almost convex.Comment: Appeared in 2003.

Meeting online or offline? Patterns and trends for co-resident couples in early 21st century Britain

Data from the 2010-12 National Survey of Sexual Attitudes and Lifestyles (NATSAL-3) are used to document trends and patterns in where co-resident couples in Britain first met, focusing specifically on the rapid rise of meeting online, which both echoes and differs from a corresponding US increase; in Britain, meeting online largely appears to have substituted for meetings in settings to which access is relatively unrestricted, e.g. pubs and public places. While meeting online appears widespread across British society, variations are identified and linked to ideas from the online dating and place of meeting literatures. Offline partner availability, and how well the processes within offline and online settings suit particular types of people, are interpreted as underpinning many of these variations. Perhaps surprisingly, meeting online does not appear class-related, and involves levels of socio-demographic homogamy that do not differ systematically from those for compositionally-heterogeneous offline settings

Square Patterns and Quasi-patterns in Weakly Damped Faraday Waves

Pattern formation in parametric surface waves is studied in the limit of weak viscous dissipation. A set of quasi-potential equations (QPEs) is introduced that admits a closed representation in terms of surface variables alone. A multiscale expansion of the QPEs reveals the importance of triad resonant interactions, and the saturating effect of the driving force leading to a gradient amplitude equation. Minimization of the associated Lyapunov function yields standing wave patterns of square symmetry for capillary waves, and hexagonal patterns and a sequence of quasi-patterns for mixed capillary-gravity waves. Numerical integration of the QPEs reveals a quasi-pattern of eight-fold symmetry in the range of parameters predicted by the multiscale expansion.Comment: RevTeX, 11 pages, 8 figure

Patterns of Design

In a straightforward meta-level shift of focus, we use design patterns as a medium and process for capturing insight about the process of design. We survey mainstream design genres, and draw conclusions about how they can help inform the design of intelligent systems

Holographic thermalization patterns

We investigate the behaviour of various correlators in N=4 super Yang Mills theory, taking finite coupling corrections into account. In the thermal limit we investigate the flow of the quasinormal modes as a function of the 't Hooft coupling. Then by using a specific model of holographic thermalization we investigate the deviation of the spectral densities from their thermal limit in an out-of-equilibrium situation. The main focus lies on the thermalization pattern with which the various plasma constituents of different energies approach their final thermal distribution as the coupling constant decreases from the infinite coupling limit. All results point towards the weakening of the usual top down thermalization pattern.Comment: HIP-2013-17-TH, Conference: C13-07-1

Patterns from preheating

The formation of regular patterns is a well-known phenomenon in condensed matter physics. Systems that exhibit pattern formation are typically driven and dissipative with pattern formation occurring in the weakly non-linear regime and sometimes even in more strongly non-linear regions of parameter space. In the early universe, parametric resonance can drive explosive particle production called preheating. The fields that are populated then decay quantum mechanically if their particles are unstable. Thus, during preheating, a driven-dissipative system exists. In this paper, we show that a self-coupled inflaton oscillating in its potential at the end of inflation can exhibit pattern formation.Comment: 4 pages, RevTex, 6 figure
