Implementing educational play to support Chinese language learning of students in Grade 5 and 6 in an Australian public school

This thesis examines how educational play (a student-centred play that relates to the curriculum and builds on authentic language environment) can support Chinese language learning for students in Grades 5 and 6 in an Australian Public School. The study is part of the Research-Oriented School-Engaged Teacher Education (ROSETE) program, requiring members to do research and teach Mandarin in Australian local schools. The study presented in this thesis addressed two research questions: 1) how educational play can help students to engage in their Chinese language learning cognitively, affectively and operatively; 2) how such strategies can facilitate students’ Chinese language learning and intercultural learning. Using qualitative action research, this research focused on eight selected students in Years 5 and 6 in the school of my Australian ROSETE placement as a trainee teacher. It built on observational data (observations by mentor; my reflective journaling; mentors’ feedback), students’ worksheets, and students’ self-evaluative feedback. The data tracked the participating eight boys’ learning during an educational play project. From the perspective of student engagement, this research suggests that educational play can generate a positive influence on students’ affective engagement and then cognitive engagement. At the same time, the study does not show significant change in students’ operative engagement. This study also examines participants’ language learning outcomes and intercultural development. Whilst the educational play project did not show a significant value for the participating students’ language learning, it appears to have had a positive value for students’ intercultural capabilities. This study evaluated the effect of educational play on students' learning, which makes a clear contribution to research on Chinese language teaching. Moreover, it benefits future beginning Chinese teachers understanding of bilingual teaching and their professional development

Magnetic anisotropy in hole-doped superconducting Ba 0.67K 0.33Fe 2As2 probed by polarized inelastic neutron scattering

We use polarized inelastic neutron scattering (INS) to study spin excitations of optimally hole-doped superconductor Ba$_{0.67}$K$_{0.33}$Fe$_2$As$_{2}$ ($T_c=38$ K). In the normal state, the imaginary part of the dynamic susceptibility, $\chi^{\prime\prime}(Q,\omega)$, shows magnetic anisotropy for energies below $\sim$7 meV with c-axis polarized spin excitations larger than that of the in-plane component. Upon entering into the superconducting state, previous unpolarized INS experiments have shown that spin gaps at $\sim$5 and 0.75 meV open at wave vectors $Q=(0.5,0.5,0)$ and $(0.5,0.5,1)$, respectively, with a broad neutron spin resonance at $E_r=15$ meV. Our neutron polarization analysis reveals that the large difference in spin gaps is purely due to different spin gaps in the c-axis and in-plane polarized spin excitations, resulting resonance with different energy widths for the c-axis and in-plane spin excitations. The observation of spin anisotropy in both opitmally electron and hole-doped BaFe$_2$As$_2$ is due to their proximity to the AF ordered BaFe$_2$As$_2$ where spin anisotropy exists below $T_N$.Comment: 5 pages, 4 figure

Polarized neutron scattering studies of magnetic excitations in electron-overdoped superconducting BaFe1.85_{1.85}Ni0.15_{0.15}As2_{2}

We use polarized inelastic neutron scattering to study low-energy spin excitations and their spatial anisotropy in electron-overdoped superconducting BaFe$_{1.85}$Ni$_{0.15}$As$_{2}$ ($T_c=14$ K). In the normal state, the imaginary part of the dynamic susceptibility, $\chi^{\prime\prime}(Q,\omega)$, at the antiferromagnetic (AF) wave vector $Q=(0.5,0.5,1)$ increases linearly with energy for $E\le 13$ meV. Upon entering the superconducting state, a spin gap opens below $E\approx 3$ meV and a broad neutron spin resonance appears at $E\approx 7$ meV. Our careful neutron polarization analysis reveals that $\chi^{\prime\prime}(Q,\omega)$ is isotropic for the in-plane and out-of-plane components in both the normal and superconducting states. A comparison of these results with those of undoped BaFe$_2$As$_2$ and optimally electron-doped BaFe$_{1.9}$Ni$_{0.1}$As$_{2}$ ($T_c=20$ K) suggests that the spin anisotropy observed in BaFe$_{1.9}$Ni$_{0.1}$As$_{2}$ is likely due to its proximity to the undoped BaFe$_2$As$_2$. Therefore, the neutron spin resonance is isotropic in the overdoped regime, consistent with a singlet to triplet excitation
