Detecting the Relationship between Adaptation and Learning Performance of Second Generation Immigrant Students in Elementary Schools

[[abstract]]This study aims to determine the relationship between student adaptation and learning performance among second generation immigrant children in elementary schools. We collected 364 students’ data to fit this scope from New Taipei City in 2013. Statistical analyses include descriptive statistics, one-way ANOVA, Pearson product-moment correlation, and multiple regression analysis. The findings reveal that the second generation immigrant students’ adaptation is pretty well compared to that of their counterparts. The learning performance is also better than that of the expected level. The result indicates there is different individual adaptation among second generation immigrant children due to their mother’s education attainment. The different interpersonal adaptation has also shown on their father’s education attainment. Mother’s occupation can explain the differences of family adaptation, learning adaptation, and student’s adaptation. The second generation immigrant student’s adaptation has shown low positive correlation with their learning performance. The findings may use to enhance second generation immigrant student’s adaptation and prompt to their learning performance.[[conferencetype]]國際[[conferencedate]]20150419~20150420[[iscallforpapers]]Y[[conferencelocation]]Hong Kon

Determining the Relationship between Academic Self-efficacy and Student Engagement by Meta-analysis

[[abstract]]Academic self-efficacy has become an important factor that will affect students’ choices of their learning task and behaviors, as well as their mentality and emotions on learning. Moreover, student engagement has been found playing a key to success in learning. This study tried to analyze the relationship between academic self-efficacy and student engagement through meta-analysis. Meta-analysis is the statistical procedure for combining data from series of studies focused on specific topics. When the effect varies from one study to the next, meta-analysis may be used to identify the variation. To determine their relationship, we selected 26 previous studies from 1990 to 2014 in the target data banks and conducted by Comprehensive Meta-analysis (CMA). The results reveal: (1) There is a relationship existed between academic self-efficacy and student engagement; (2) In different school level, that only shows the moderating effect on academic self-efficacy and behavioral engagement.[[conferencetype]]國際[[conferencedate]]20150419~20150420[[iscallforpapers]]Y[[conferencelocation]]Hong Kon

Photon Polarization in the b->s gamma processes in the Left-Right Symmetric Model

The circular-polarization of the photon in the radiative B decays is dominantly left-handed in the Standard Model (SM), but the right-handed polarization may be enhanced in some new physics models with right-handed currents, such as the Left-Right Symmetric Model (LRSM). In this article, we investigate how large this wrong polarization could be within the allowed parameter space of the LRSM. We show that in LRSM, the right-handed polarization of the photon in the $b\to s\gamma$ processes could be largely enhanced by the $W_L-W_R$ mixing contributions because of the helicity flip on the internal top quark line of the penguin diagrams and the enhancement by the CKM factor $V_{ts}^R/V_{ts}^L$. We discuss the sensitivity of the proposed methods to determine the $b\to s\gamma$ photon polarization to the LRSM as well as their complementary role compared to the direct search of right-handed charged gauge bosons at LHC.Comment: 30pages, 5 figures, published version; references adde

Implications on the first observation of charm CPV at LHCb

Very recently, the LHCb Collaboration observed the $CP$ violation (CPV) in the charm sector for the first time, with $\Delta A_{CP}^{\rm dir}\equiv A_{CP}(D^0\to K^+K^-)-A_{CP}(D^0\to \pi^+\pi^-)=(-1.54\pm0.29)\times10^{-3}$. This result is consistent with our prediction of $\Delta A_{CP}^{\rm SM}=(-0.57\sim -1.87)\times 10^{-3}$ obtained in the factorization-assisted topological-amplitude (FAT) approach in [PRD86,036012(2012)]. It implies that the current understanding of the penguin dynamics in charm decays in the Standard Model is reasonable. Motivated by the success of the FAT approach, we further suggest to measure the $D^+\to K^+K^-\pi^+$ decay, which is the next potential mode to reveal the CPV of the same order as $10^{-3}$.Comment: 10 page

Selecting the Strategies for Implementing Teacher Evaluation in Junior High Schools

[[abstract]]This study aims to select better strategies for implementing teacher evaluation in junior high schools. Based on the fuzzy questionnaire, this study collected the data from teachers’ perceptions on importance and feasibility in related teacher evaluation strategies. The survey was targeted at 17 junior high school and 400 teachers in New Taipei city, Taiwan. The return rate of fuzzy questionnaires is 89.5%. This study transformed the interval data by way of fuzzy means, defuzzification, and fuzzy distance. The result reveals, for the purposes of teacher evaluation, the possible strategies are improving the quality of teaching and assisting teachers in their professional development; For the principles of teacher evaluation, the possible strategies including set the evaluation indicators according to teachers’ teaching fields and let teachers participate in related decision making; For related methods of teacher evaluation, the possible strategies are classroom observation, using teacher self-evaluation, and using teaching portfolio. The inappropriate strategy is evaluated by parent questionnaires. The study suggests ten strategies for improving the current teacher evaluation system.[[booktype]]紙

Fuzzy Correlation among Student Engagement and Interpersonal Interactions

[[abstract]]Student engagement has become a hot issue in education settings. Previous studies have provided a profound knowledge to tackle this issue from different perspectives. While engagement or not is an ambiguous question for student learning, it is not easy to reflect on a crisp answer in a traditional way. Similarly, the students’ interpersonal interactions among the teachers, classmates, and parents have shown uncertainly relationship with their engagement. This study aims to explore the issues by using self-designed fuzzy questionnaire as an example for high school teachers. Fuzzy means, centroids, variances, and fuzzy correlations have been transformed. The results reveal some indicators have negative tendency fuzzy relationships. The fuzzy correlation coefficients did not display their significant differences in this case study. This study has demonstrated that the fuzzy statistics can provide an example to tackle the similar issue on a class basis in education settings.[[sponsorship]]Tamkang University[[notice]]補正完

Branching ratios and direct CP asymmetries in D→PVD\to PV decays

We study the two-body hadronic $D\to PV$ decays, where $P$ ($V$) denotes a pseudoscalar (vector) meson, in the factorization-assisted topological-amplitude approach proposed in our previous work. This approach is based on the factorization of short-distance and long-distance dynamics into Wilson coefficients and hadronic matrix elements of four-fermion operators, respectively, with the latter being parametrized in terms of several nonperturbative quantities. We further take into account the $\rho$-$\omega$ mixing effect, which improves the global fit to the branching ratios involving the $\rho^0$ and $\omega$ mesons. Combining short-distance dynamics associated with penguin operators and the hadronic parameters determined from the global fit to branching ratios, we predict direct $CP$ asymmetries. In particular, the direct $CP$ asymmetries in the $D^0\to K^0\overline{K}^{*0},~\overline{K}^0K^{*0}$, $D^+\to\pi^+\rho^0$, and $D_s^+\to K^+\omega,~K^+\phi$ decays are found to be of ${\cal O}(10^{-3})$, which can be observed at the LHCb or future Belle II experiment. We also predict the $CP$ asymmetry observables of some neutral $D$ meson decays.Comment: 16 pages, 2 figure
