    Teacher Candidates’ Learning Gains: The Tale of Two Co-Teachers

    Get PDF
    Co-teaching during the student teaching experience has been given increased attention among researchers and teacher educators. Co-teaching facilitates an apprenticeship arrangement that encourages modeling of classroom practice for the candidate and provides a chance to implement directly what is being learned. This qualitative study explored teacher candidates’ learning gains using the co-teaching model for student teaching. Teacher candidates were able to see more clearly the dynamics of how a classroom works and the process by which teachers plan lessons, implement curriculum, and manage the many duties of a classroom teacher

The purpose of the work was to create a sensor for automated potentiometric monitoring of the ammonium ions content in flowing conditions. As a result of the study, the reference electrode design was developed. This is an ion-selective electrode lowered into a buffer system with cation exchanger. The work presents a potentiometric analysis of ammonium ions model solutions, the study of temperature interfering effect, and system's stability determination

    Search for CP violation in D+→ϕπ+ and D+s→K0Sπ+ decays

    Get PDF
    A search for CP violation in D + → ϕπ + decays is performed using data collected in 2011 by the LHCb experiment corresponding to an integrated luminosity of 1.0 fb−1 at a centre of mass energy of 7 TeV. The CP -violating asymmetry is measured to be (−0.04 ± 0.14 ± 0.14)% for candidates with K − K + mass within 20 MeV/c 2 of the ϕ meson mass. A search for a CP -violating asymmetry that varies across the ϕ mass region of the D + → K − K + π + Dalitz plot is also performed, and no evidence for CP violation is found. In addition, the CP asymmetry in the D+s→K0Sπ+ decay is measured to be (0.61 ± 0.83 ± 0.14)%

    Search for the lepton-flavor-violating decays Bs0→e±Ό∓ and B0→e±Ό∓

    A search for the lepton-flavor-violating decays Bs0→e±Ό∓ and B0→e±Ό∓ is performed with a data sample, corresponding to an integrated luminosity of 1.0  fb-1 of pp collisions at √s=7  TeV, collected by the LHCb experiment. The observed number of Bs0→e±Ό∓ and B0→e±Ό∓ candidates is consistent with background expectations. Upper limits on the branching fractions of both decays are determined to be B(Bs0→e±Ό∓)101  TeV/c2 and MLQ(B0→e±Ό∓)>126  TeV/c2 at 95% C.L., and are a factor of 2 higher than the previous bounds
