Teaching Competency of Teacher of Building Drawing Skill In SMK N 1 Sedayu Bantul

Teacher is an important element for the improvement of Indonesia’s education because teacher has a role to delivery subject matter directly to the student. The teacher must have good teaching competency so the aim of learning can be achieved. This research is explain how teaching competency in productive subject matter, building drawing course in SMK N 1 Sedayu Bantul. In this research the writer take research object was 6 teachers of building drawing course in SMK N 1 Sedayu Bantu. Data collection technique was indirect observation in 3 kinds of questionnaire. First questionnaire was for student participant, the second was for head master participant. The questionnaire consisted of 4 answer choice, (BS) very good, (B) good,(K) minus,(KS) very minus. The third was portfolio questionnaire for teacher participant. Data of this research was analyzed with descriptive statistics technique and descriptive quantitative. Result of the research show that in general teaching competency teacher in productive subject matter, building drawing course SMK N 1 Sedayu Bantul can be categorized in good category. From 6 indicators of teaching competency 83,3% were good and 16,66% was minus. The indicators categorized as good category were indicator of teaching instrument usage, giving motivation, indicator of assessment, the use of teaching method, interaction between teacher and student, However, for presentation matter was categorized as minus. Second, result of this research indicated that there was correlation between head master assessment and student assessment for teaching competency. The student assessment was more objective than head master’s assessment because the number of student was bigger than the number of head masters that just one person. The student had enough time to fill up the questionnaire so the result was more accurate. The student was more understand because the teacher aught them every day. Third, this research indicated that there was no correlation between assessment of teacher portfolio and their teaching competency, it means, for the student, high result of portfolio assessment didn’t increase the teachers’ teaching competency. So, portfolio assessment can’t be absolute reference to assess the teacher competency. Keyword: Teaching competency, Productive subject matter, Pedagogic competency, Personal competenc

A detailed investigation into near degenerate exponential random graphs

The exponential family of random graphs has been a topic of continued research interest. Despite the relative simplicity, these models capture a variety of interesting features displayed by large-scale networks and allow us to better understand how phases transition between one another as tuning parameters vary. As the parameters cross certain lines, the model asymptotically transitions from a very sparse graph to a very dense graph, completely skipping all intermediate structures. We delve deeper into this near degenerate tendency and give an explicit characterization of the asymptotic graph structure as a function of the parameters.Comment: 15 pages, 3 figures, 2 table

Emergent Symmetry on Black Hole Horizons

For a stationary and axisymmetric black hole, there is a natural way to split the fields into a probe sector and a background sector. The equations of motion for the probe sector enjoy a significantly enhanced symmetry on the black hole horizon. The extended symmetry is conformal in four dimensions, while in higher dimensions it is much bigger. This puts conformal symmetry at the bottom of the ladder of symmetries that can arise on black hole horizons in generic dimensions.Comment: 8 page

Spontaneous Nambu-Goldstone Currents Generation Driven by Mismatch

We review recent progress of understanding and resolving instabilities driven by mismatch between the Fermi surfaces of the pairing quarks in 2-flavor color superconductor. With the increase of mismatch, the 2SC phase exhibits chromomagnetic instability as well as color neutral baryon current instability. We describe the 2SC phase in the nonlinear realization framework, and show that each instability indicates the spontaneous generation of the corresponding pseudo Nambu-Golstone current. The Nambu-Goldstone currents generation state covers the gluon phase as well as the one-plane wave LOFF state. We further point out that, when charge neutrality condition is required, there exists a narrow unstable LOFF (Us-LOFF) window, where not only off-diagonal gluons but the diagonal 8-th gluon cannot avoid the magnetic instability. In this Us-LOFF window, the diagonal magnetic instability cannot be cured by off-diagonal gluon condensate in the color superconducting phase.Comment: 22 pages, no figures; contribution to the proceedings of the INT workshop "Pairing in fermionic systems", Seattle, September 19-23, 200
