PENGARUH PERMAINAN TRADISIONAL TERHADAP KERJASAMA PADA SISWA SEKOLAH MENENGAH ATAS

Dalam upaya meningkatkan nilai-nilai kerjasama pada siswa sekolah menengah atas diperlukan bahan ajar yang tepat untuk diberikan kepada siswa. Salah satu bahan ajar yang dapat diterapkan adalah permainan tradisional. Permainan tradisional merupakan permainan yang berasal dari Indonesia yang banyak mengandung nilai afektif dan psikomotor yang berguna untuk pertumbuhan anak. Penelitian ini bertujuan untuk mengetahui bagaimana pengaruh permainan tradisional terhadap kerjasama pada siswa sekolah menengah atas. Metode yang digunakan dalam penelitian ini adalah metode eksperimen. Populasi dalam penelitian ini adalah siswa kelas XI di SMAK 2 BPK Penabur Bandung tahun ajaran 2015/2016. Sampel dalam penelitian ini diambil seluruhnya menggunakan teknik random sampling sebanyak 50 orang. Analisis statistik yang digunakan adalah analisis uji t dengan kesamaan dua rata-rata satu pihak.Pada variabel kerjasama hasil pengujian menunjukan bahwa thitung (2,651`) lebih besar dari ttabel (2,010). Kriteria pengujian adalah tolak Ho jika thitung > ttabel pada taraf nyata α = 0,05 dengan (dk) = 28. Dalam hal ini t hitung berada pada daerah penolakan Ho, jadi Ho ditolak dan H1 diterima yang artinya terdapat pengaruh permainan tradisional terhadap kerjasama pada siswa sekolah menengah atas. ;---In an effort to increase the values of cooperation/ teamplay on high school students, the right teaching material has to be given to student, the teaching material that can be applied is Traditional Game. Traditional games that originally came from Indonesia have a lot of effective values and psychomotor values which are important for children development. This research aims to evaluate the effect of traditional game towards students’ teamplay in High School. The methodology used in this research is experimental method. The population in this research is class XI students in SMAK 2 BPK Penabur Bandung 2015/2016. The sample in this research is taken with random sampling of 50 students. The statistical analysis used is the analysis of the t-test with an average similarity of the two variables. On cooperation/teamplay variable the testing results show that thitung (2,651) is greater than ttabel (2,010). The testing criteria is rejected if Ho thitung > ttabel the real level α = 0.05 (df) = 28. In this case t hitung is in the region of Ho rejection, so Ho refused and H1 accepted which means there are significant effect of traditional game against cooperation/ teamplay on high school students

Multistability and nonsmooth bifurcations in the quasiperiodically forced circle map

It is well-known that the dynamics of the Arnold circle map is phase-locked in regions of the parameter space called Arnold tongues. If the map is invertible, the only possible dynamics is either quasiperiodic motion, or phase-locked behavior with a unique attracting periodic orbit. Under the influence of quasiperiodic forcing the dynamics of the map changes dramatically. Inside the Arnold tongues open regions of multistability exist, and the parameter dependency of the dynamics becomes rather complex. This paper discusses the bifurcation structure inside the Arnold tongue with zero rotation number and includes a study of nonsmooth bifurcations that happen for large nonlinearity in the region with strange nonchaotic attractors.Comment: 25 pages, 22 colored figures in reduced quality, submitted to Int. J. of Bifurcation and Chaos, a supplementary website (http://www.mpipks-dresden.mpg.de/eprint/jwiersig/0004003/) is provide

El Cabri como potenciador en el estudiante del pensamiento geométrico

Enmarcándonos en el contexto mundial y reconociendo el acelerado avance tecnológico, es notoria la necesidad de implementar un plan de estudios apoyado en el uso de nuevas tecnologías de la información y la comunicación, que forme al estudiante y lo motive en la construcción de su propio conocimiento, alcanzando de esta manera su participación activa y proyección hacia el campo de la solución de problemas de su entorno. Desde esta propuesta se asume que el desarrollo del pensamiento matemático, proporciona una estructura mental adecuada para plantear y resolver problemas de tipo métrico y geométrico, haciendo uso de un contexto virtual, el software especializado Cabri, que como herramienta tecnológica proporciona una dinámica especial para que el estudiante pueda elaborar demostraciones gráficas y conjeturar algunas hipótesis planteadas. Esta estrategia didáctica de intervención en el aula, se empleó con estudiantes del sector oficial de la Institución Educativa Marcelino Champagnat de Armenia en el marco del proyecto Juega y Construye la matemática142, con jóvenes entre los 12 y 16 años de los grados 8° y 9°

The Maslov Gerbe

Let Lag(E) be the grassmannian of lagrangian subspaces of a complex symplectic vector space E. We construct a Maslov class which generates the second integral cohomology of Lag(E), and we show that its mod 2 reduction is the characteristic class of a flat gerbe with structure group Z_2. We explain the relation of this gerbe to the well-known flat Maslov line bundle with structure group Z_4 over the real lagrangian grassmannian, whose characteristic class is the mod 4 reduction of the real Maslov class.Comment: 8 page

Lens space surgeries on A'Campo's divide knots

It is proved that every knot in the major subfamilies of J. Berge's lens space surgery (i.e., knots yielding a lens space by Dehn surgery) is presented by an L-shaped (real) plane curve as a "divide knot" defined by N. A'Campo in the context of singularity theory of complex curves. For each knot given by Berge's parameters, the corresponding plane curve is constructed. The surgery coefficients are also considered. Such presentations support us to study each knot itself, and the relationship among the knots in the set of lens space surgeries.Comment: 26 pages, 19 figures. The proofs of Theorem 1.3 and Lemma 3.5 are written down by braid calculus. Section 4 (on the operation Adding squares) is revised and improved the most. Section 5 is adde

Opposing effects of bisphosphonates and advanced glycation end-products on osteoblastic cells

Patients with long-standing Diabetes mellitus can develop osteopenia and osteoporosis. We have previously shown that advanced glycation endproducts reduce the bone-forming activity of osteoblasts. Bisphosphonates are used for the treatment of various bone disorders, since they reduce osteoclastic function and survival, and stimulate osteoblastic bone-forming capacity. In this work we have investigated whether bisphosphonates are able to revert advanced glycation endproducts-induced deleterious effects in osteoblasts. MC3T3E1 and UMR106 osteoblastic cells were incubated with control or advanced glycation endproducts-modified bovine serum albumin, in the presence or absence of different doses of the bisphosphonates Alendronate, Pamidronate or Zoledronate. After 24–72 h of culture, we evaluated their effects on cell proliferation and apoptosis, type-1 collagen production, alkaline and neutral phosphatase activity, and intracellular reactive oxygen species production. Advanced glycation endproducts significantly decreased osteoblast proliferation, alkaline phosphatase activity and type 1 collagen production, while increasing osteoblastic apoptosis and reactive oxygen species production. These effects were completely reverted by low doses (10−8 M) of bisphosphonates. High doses of bisphosphonates (10−4–10−5 M) were toxic for osteoblasts. Nifedipine (L-type calcium channel blocker) did not affect the advanced glycation endproducts-induced decrease in osteoblastic proliferation, although it blocked the reversion of this effect by 10−8 M Alendronate. Both advanced glycation endproducts and Alendronate inhibited the activity of intracellular neutral phosphatases. In conclusion, we show that bisphosphonates revert the deleterious actions of advanced glycation endproducts on osteoblastic cells, and that these effects of bisphosphonates depend on: (a) Ca2+ influx through L-type voltage-sensitive channels, and (b) blockage of advanced glycation endproducts-induced reactive oxygen species generation
