    Penelitian ini bertujuan untuk mengetahui hasil belajar matematika siswa yang mengikuti pembelajaran dengan model pembelajaran kooperatif tipe STAD serta hasil belajar matematika siswa yang mengikuti pembelajaran biasa di kelas VII SMPN 31 Padang. Jenis penelitian ini adalah eksperimen dengan model rancangan Randomized Control Group Only Design. Populasi dalam penelitian ini adalah siswa kelas VII SMPN 31 Padang, kecuali kelas VII1 karena termasuk kelas unggul dan sampel dalam penelitian ini adalah Kelas VII4 dengan 39 orang siswa sebagai kelas eksperimen dan kelas VII6 dengan38 orang siswa sebagai kelas kontrol. Instrumen penelitian yang digunakan adalah tes hasil belajar. Pengolahan data hasil tes akhir dilakukan melalui uji hipotesis yang menggunakan uji-t. Pada selang kepercayaan 95% dengan α = 0,05 diperoleh nilai thitung = 4,43 dan ttabel = 1,67. Rata-rata hasil tes akhir siswa kelas eksperimen adalah 71,85 sedangkan rata-rata hasil tes akhir siswa kelas kontrol adalah59,42, karena thitung > ttabel berarti hipotesis penelitian ini diterima. Sehingga dapat disimpulkan bahwa hasil belajar matematika siswa dengan menggunakan Model Pembelajaran Kooperatif Tipe STAD lebih tinggi dari hasil belajar matematika siswa dengan menggunakan model pembelajaran bias

    Synthesis And Characterization Of (pyNO−)2GaCl: A Redox-Active Gallium Complex

    We report the synthesis of a gallium complex incorporating redox-active pyridyl nitroxide ligands. The (pyNO−)2GaCl complex was prepared in 85% yield via a salt metathesis route and was characterized by 1H and 13C NMR spectroscopies, X-ray diffraction, and theory. UV–Vis absorption spectroscopy and electrochemistry were used to access the optical and electrochemical properties of the complex, respectively. Our discussion focuses primarily on a comparison of the gallium complex to the corresponding aluminum derivative and shows that although the complexes are very similar, small differences in the electronic structure of the complexes can be correlated to the identity of the metal

    Prediction of discharge walking ability from initial assessment in a stroke inpatient rehabilitation facility population

    Objectives: To (1) determine which clinical assessments at admission to an inpatient rehabilitation facility (IRF) most simply predict discharge walking ability, and (2) identify a clinical decision rule to differentiate household versus community ambulators at discharge from an IRF. Design: Retrospective cohort study. Setting: IRF. Participants: Two samples of participants (n=110 and 159) admitted with stroke. Interventions: A multiple regression determined which variables obtained at admission (age, time from stroke to assessment, Motricity Index, somatosensation, Modified Ashworth Scale, FIM, Berg Balance Scale, 10-m walk speed) could most simply predict discharge walking ability (10-m walk speed). A logistic regression determined the likelihood of a participant achieving household (= 0.4-0.8m/s; >0.8m/s) ambulation at the time of discharge. Validity of the results was evaluated on a second sample of participants. Main Outcome Measure: Discharge 10-m walk speed. Results: Admission Berg Balance Scale and FIM walk item scores explained most of the variance in discharge walk speed. The odds ratio of achieving only household ambulation at discharge was 20 (95% confidence interval [CI], 6-63) for sample I and 32 (95% CI, 10-96) for sample 2 when the combination of having a Berg Balance Scale score of <= 20 and a FIM walk item score of 1 or 2 was present. Conclusions: A Berg Balance Scale score of <= 20 and a FIM walk item score of 1 or 2 at admission indicates that a person with stroke is highly likely to only achieve household ambulation speeds at discharge from an IRF

    Seasonal cultivated and fallow cropland mapping using MODIS-based automated cropland classification algorithm

    Increasing drought occurrences and growing populations demand accurate, routine, and consistent cultivated and fallow cropland products to enable water and food security analysis. The overarching goal of this research was to develop and test automated cropland classification algorithm (ACCA) that provide accurate, consistent, and repeatable information on seasonal cultivated as well as seasonal fallow cropland extents and areas based on the Moderate Resolution Imaging Spectroradiometer remote sensing data. Seasonal ACCA development process involves writing series of iterative decision tree codes to separate cultivated and fallow croplands from noncroplands, aiming to accurately mirror reliable reference data sources. A pixel-by-pixel accuracy assessment when compared with the U.S. Department of Agriculture (USDA) cropland data showed, on average, a producer's accuracy of 93% and a user's accuracy of 85% across all months. Further, ACCA-derived cropland maps agreed well with the USDA Farm Service Agency crop acreage-reported data for both cultivated and fallow croplands with R-square values over 0.7 and field surveys with an accuracy of >= 95% for cultivated croplands and >= 76% for fallow croplands. Our results demonstrated the ability of ACCA to generate cropland products, such as cultivated and fallow cropland extents and areas, accurately, automatically, and repeatedly throughout the growing season

    The brain recovery core: Building a system of organized stroke rehabilitation and outcomes assessment across the continuum of care

    Get PDF
    none10siThis Special Interest article describes a multidisciplinary, interinstitutional effort to build an organized system of stroke rehabilitation and outcomes measurement across the continuum of care. This system is focused on a cohort of patients who are admitted with the diagnosis of stroke to our acute facility, are discharged to inpatient and/or outpatient rehabilitation at our free-standing facility, and are then discharged to the community. This article first briefly explains the justification, goals, and purpose of the Brain Recovery Core system. The next sections describe its development and implementation, with details on the aspects related to physical therapy. The article concludes with an assessment of how the Brain Recovery Core system has changed and improved delivery of rehabilitation services. It is hoped that the contents of this article will be useful in initiating discussions and potentially facilitating similar efforts among other centers.mixedLang, Catherine E.; Bland, Marghuretta D.; Connor, Lisa Tabor; Fucetola, Robert; Whitson, Michelle; Edmiaston, Jeff; Karr, Clayton; Sturmoski, Audra; Baty, Jack; Corbetta, MaurizioLang, Catherine E.; Bland, Marghuretta D.; Connor, Lisa Tabor; Fucetola, Robert; Whitson, Michelle; Edmiaston, Jeff; Karr, Clayton; Sturmoski, Audra; Baty, Jack; Corbetta, Maurizi
