Peningkatan Aktivitas Siswa dalam Pembelajaran Matematika dengan Metode Inkuiri di Kelas V Sekolah Dasar Negeri 08 Padang Pio

The problem in this study is an effort to increase the activity of students in learning mathematics with the method of inquiry in class V Elementary School District 08 Padang Pio.Tujuan this study was to obtain information / description of the implementation of the inquiry method to increase the activity of students in learning mathematics class V. The benefit of this research is to provide new knowledge and skills through the actions of the teacher in tindakan.Metode research studies used in this research is descriptive method with qualitative approach. data collection techniques in this study is the technique of direct observation and direct communication techniques. Tools that leverage the data used observasi.Penelitian sheet is done for 2 cycles with the results obtained from the base line to the second cycle of physical activity 19.04%, 73.80% and 97.61%. Mental activity that is 0%, 38.15% and 78.54%. Emotional activity that is 0%, 69.99% and 89.99%. From the results obtained it can be concluded that the application of methods of inquiry in teaching Mathematics was found to increase physical activity, mental and emotional student

Pion and Sigma Polarizabilities and Radiative Transitions

Fermilab E781 plans measurements of gamma-Sigma and $\gamma$-pion interactions using a 600 GeV beam of Sigmas and pions, and a virtual photon target. Pion polarizabilities and radiative transitions will be measured in this experiment. The former can test a precise prediction of chiral symmetry; the latter for a_1(1260) ----> pi + gamma is important for understanding the polarizability. The experiment also measures polarizabilities and radiative transitions for Sigma hyperons. The polarizabilities can test predictions of baryon chiral perturbation theory. The radiative transitions to the Sigma*(1385) provide a measure of the magnetic moment of the s-quark. Previous experimental and theoretical results for gamma-pi and gamma-Sigma interactions are given. The E781 experiment is described.Comment: 13 pages text (tex), Tel Aviv U. Preprint TAUP 2204-94, uses Springer-Verlag TEX macro package lecproc.cmm (appended at end of tex file, following \byebye), which requires extracting lecproc.cmm and putting this file in your directory in addition to the tex file (mmcd.tex) before tex processing. lecproc.cmm should be used following instructions and guidelines available from Springer-Verlag. Submitted to the Proceedings of Workshop on Chiral Dynamics, Massachusetts Institute of Technology, July 1994, Eds. A. Bernstein, B. Holstein. Replaced Oct. 4 to add TAUP preprint number. Replaced Oct. 12 to correct Pb target thickness from 1.3% interaction to 0.3
