What is the impact of blogging used with self-monitoring strategies for adolescents who struggle with writing?

Plan B Paper. 2012. Master of Science in Education- Reading--University of Wisconsin-River Falls. Teacher Education Department. 28 leaves. Includes bibliographical references (leaves 25-26).Writing is an onerous task for those who struggle with the skill. The basic prerequisites of organizing thoughts, transcribing thoughts into words, and writing down those words is fundamental to the more advanced skills of developing a sense of audience, writing with voice and applying conventions. Without proficient skills, students who cannot write, do not write. Positive attitude toward the process of writing suffers. Time spent on actual writing is limited. As a consequence, writing skill does not develop. Students who struggle with writing can be supported in their skill development through self-monitoring strategies. Self-monitoring strategies for writing give students a systematic process to know how to approach a writing task. The clear step-by-step process breaks down difficult skills and allows students to build proficiency through guided practice and eventually, independence. This action research project explored the impact of using self-monitoring strategies with the 21st century skill of blogging within a Writer's Workshop instructional model. Sixteen students (eleven males, five females) in grades 6-8th participated in a twelve week study. Target writing skills of fluency, stamina, motivation, awareness of audience and participation in peer review were measured for changes over the course of the study. Students were instructed in the use of self-monitoring strategies focusing on increasing word counts in correct word sequence timings, on-command prompt passages, and formal writing process pieces. Blogging was introduced and used to apply target skills to a digital writing setting. Each student learned self monitoring strategies to compose posts in personal blogs and to read and comment on other students' blogs. Pre-and post-writing attitude survey, correct word sequence timings and writing samples were taken throughout the study to assess each students' skill level and attitude toward writing. The group showed average gains of 34% in correct word sequence and 66% in word counts of process writing pieces. Qualitative data and quantitative data demonstrate that writing skills and attitudes toward writing also showed positive development when self-monitoring strategies were used to support the writing tasks of blogging in a Writer's Workshop model

Stability of the proton-to-electron mass ratio

We report a limit on the fractional temporal variation of the proton-to-electron mass ratio as, obtained by comparing the frequency of a rovibrational transition in SF6 with the fundamental hyperfine transition in Cs. The SF6 transition was accessed using a CO2 laser to interrogate spatial 2-photon Ramsey fringes. The atomic transition was accessed using a primary standard controlled with a Cs fountain. This result is direct and model-free

Updated results on prototype chalcogenide fibers for 10-um wavefront spatial filtering

The detection of terrestrial planets by Darwin/TPF missions will require extremely high quality wavefronts. Single-mode fibers have proven to be powerful beam cleaning components in the near-infrared, but are currently not available in the mid-infrared where they would be critically needed for Darwin/TPF. In this paper, we present updated measurements on the prototype chalcogenide fibers we are developing for the purpose of mid-infrared spatial filtering. We demonstrate the guiding property of our 3rd generation component and we characterize its filtering performances on a 4 mm length: the far-field radiation pattern matches a Gaussian profile at the level of 3% rms and 13% pk-pk.Comment: 4 pages, 5 figures, to appear in the proceedings of the conference "Toward Other Earths, Darwin/TPF and the search for extrasolar terrestrial planets", held in Heidelberg, Germany, 22-25 April 2003, ESA SP-53

Two-Way Optical Frequency Comparisons Over 100km Telecommunication Network Fibers

By using two-way frequency transfer, we demonstrate ultra-high resolution comparison of optical frequencies over a telecommunication fiber link of 100 km operating simultaneously digital data transfer. We first propose and experiment a bi-directional scheme using a single fiber. We show that the relative stability at 1 s integration time is 7 10^18 and scales down to 5 10^21. The same level of performance is reached when an optical link is implemented with an active compensation of the fiber noise. We also implement a real-time two-way frequency comparison over a uni-directional telecommunication network using a pair of parallel fibers. The relative frequency stability is 10^15 at 1 s integration time and reaches 2 10^17 at 40 000 s. The fractional uncertainty of the frequency comparisons was evaluated for the best case to 2 10^20. These results open the way to accurate and high resolution frequency comparison of optical clocks over intercontinental fiber networks

Absolute frequency measurement of 12C16O2 laser lines with a femtosecond laser comb and new determination of the 12C16O2 molecular constants and frequency grid

Absolute frequency measurements of a CO2 laser stabilized on saturated absorption resonances of CO2 laser lines are reported. They were performed using a femtosecond-laser frequency comb generator and two laser diodes at 852 nm and 782 nm as intermediate oscillators, with their frequency difference phase-locked to the CO2 laser. 20 12C16O2 laser lines in the P and R bands at 9 µm were measured with a relative uncertainty of a few 10-12 limited by the CO2 frequency reproducibility. A new determination of the CO2 molecular constants was obtained from these data and previous measurements in the 10 µm band. The CO2 frequency grid was also calculated, with an improvement of two orders of magnitude compared to the previous grid of Maki et al [A.G. Maki, C.C. Chou, K. Evenson, L.R. Zink and J.T. Shy, J. Mol. Spectrosc. 167, (1994) 211-224]

Ultra-stable long distance optical frequency distribution using the Internet fiber network

We report an optical link of 540 km for ultrastable frequency distribution over the Internet fiber network. The stable frequency optical signal is processed enabling uninterrupted propagation on both directions. The robustness and the performance of the link are enhanced by a cost effective fully automated optoelectronic station. This device is able to coherently regenerate the return optical signal with a heterodyne optical phase locking of a low noise laser diode. Moreover the incoming signal polarization variation are tracked and processed in order to maintain beat note amplitudes within the operation range. Stable fibered optical interferometer enables optical detection of the link round trip phase signal. The phase-noise compensated link shows a fractional frequency instability in 10 Hz bandwidth of 5x10-15 at one second measurement time and 2x10-19 at 30 000 s. This work is a significant step towards a sustainable wide area ultrastable optical frequency distribution and comparison network

Probing weak force induced parity violation by high resolution mid-infrared molecular spectroscopy

To date no experiment has reached the level of sensitivity required to observe weak nuclear force induced parity violation (PV) energy differences in chiral molecules. In this paper, we present the approach, adopted at Laboratoire de Physique des Lasers (LPL), to measure frequency differences in the vibrational spectrum of enantiomers. We review different spectroscopic methods developed at LPL leading to the highest resolutions, as well as 20 years of CO2 laser stabilization work enabling such precise measurements. After a first attempt to observe PV vibrational frequency shifts using sub-Doppler saturated absorption spectroscopy in a cell, we are currently aiming at an experiment based on Doppler-free two-photon Ramsey interferometry on a supersonic beam. We report on our latest progress towards observing PV with chiral organo-metallic complexes containing a heavy rhenium atom
