THE IMPLEMENTATION OF COOPERATIVE INTEGRATED READING AND COMPOSITION (CIRC) IN TEACHING READING. Ulfah Bunga Tree Wasmad No. Reg 117010007

The CIRC method is potentially improving reading comprehension skill, because the aspect of the CIRC method possibly makes the students exchange the knowledge in learning process. The present classroom action investigation was basically triggered out by the fact that the students under study still faced problem in reading comprehension. In this classroom action study, the teaching and learning processes were divided into two cycles where each cycle consisted of two cycles. The obtained data of the present classroom action study were collected through the administration of pre-test, post-test, and questionnaire which analysed descriptively. The present classroom action study was started with administering IR or pre-test to the subject under study. The results of the data analysis of the pre-test score showed the mean figure of 30,70. The results of the data analysis of the reflection or post test scores in cycle I (post-test1 and post-test 2) showed the increasing mean figures of 46,61 and 57. The results of the data analysis of the reflection or post test scores obtained by the subject under study in cycle II (post-test 1 and post-test2) pointed out the increasing mean figures of 73,23 and 86,76. Compared with the mean figure of IR scores, the mean figure obtained by the subject under study for each session was convincingly much higher than the mean figure of pre test scores. The grand mean figure of the reflection or post test scores obtained by the subject under study in cycle I was 51,80 and in cycle II was 80. There was a significant difference of the grand mean figure between cycle I and cycle II. The difference of the grand mean figure of cycle I and cycle II was 28.2 (80 – 51,80). These findings clearly showed that CIRC could improve the reading comprehension of the eighth grade students of SMPN 1 Lembang. The result of the present classroom action study were in line with the presented research findings, teaching reading comprehension by using CIRC Method gave significant improvement. Key words: Cooperative Learning, Teaching Reading, and Teaching Composition

The Use of Pictures as Media to Improve Students’ Speaking Ability. Cries Tia NofiaDewi NRP. 107010008

This final paper is an action research. The aim of the study is to know the use of pictures in improving seventh grade students’speaking ability. There is no doubt that speaking is one of the most difficult skill for second language. The seventh grade of SMP Kemah Indonesia 4 Bandung also faced the same problem. Based on the observation, it was found that the students’ speaking ability in descriptive study was still far from expectation. This research was conducted in a classroom action research in order to improve students’ speaking ability. This study used classroom action research (PTK), It consists of four steps in conducting the action research : planning, acting, observing and reflecting. This action research was done in two cycles. The results of this research indicated that using pictures can improve students’ speaking ability in descriptive study especially in describing a picture. Morover, the students were able to improve their ability in speaking. Based on the result of classroom action research, the conclusion shows that pictures media are appropriate to help and guide the students’ speaking in descriptive study. Teaching descriptive by using pictures media is an affective way to solve the problem faced by students in terms of developing ideas to speaking in descriptive study

Solvate-dependent spin crossover and exchange in cobalt(II) oxazolidine nitroxide chelates

Two oxazolidine nitroxide complexes of cobalt(II), [Co(II)(L(*))2](B(C6F5)4)2*CH2Cl2 (1) and [Co(II)(L(*))2](B(C6F5)4)2*2Et2O (2), where, L(*) is the tridentate chelator 4,4-dimethyl-2,2-bis(2-pyridyl)oxazolidine N-oxide, have been investigated by crystallographic, magnetic, reflectivity, and theoretical (DFT) methods. This work follows on from a related study on [Co(II)(L(*))2](NO3)2 (3), a multifunctional complex that simultaneously displays magnetic exchange, spin crossover, and single molecule magnetic features. Changing the anion and the nature of solvation in the present crystalline species leads to significant differences, not only between 1 and 2 but also in comparison to 3. Structural data at 123 and 273 K, in combination with magnetic data, show that at lower temperatures 1 displays low-spin Co(II)-to-radical exchange with differences in fitted J values in comparison to DFT (broken symmetry) calculated J values ascribed to the sensitive influence of a tilt angle (θ) formed between the Co(dz(2)) and the trans-oriented O atoms of the NO radical moieties in L(*). Spin crossover in 1 is evident at higher temperatures, probably influenced by the solvate molecules and crystal packing arrangement. Complex 2 remains in the high-spin Co(II) state between 2 and 350 K and undergoes antiferromagnetic exchange between Co-radical and radical-radical centers, but it is difficult to quantify. Calculations of the magnetic orbitals, eigenvalue plots, and the spin densities at the Co and radical sites in 1 and 2 have yielded satisfying details on the mechanism of metal-radical and radical-radical exchange, the radical spins being in π*NO orbitals
