| Abstrak | : | The current study, a uniquely challenging failed partnership, describes via an exploratory case study design the endeavors of a single middle school science teacher as he translated the reform messages of the Next Generation Science Standards into actual classroom practice. Data collected from both within and outside of the classroom revealed the pathways of change pursued and resisted as multiple data sources were charted within the teacher of interest’s interconnected model of professional growth. Findings reveal how multiple drivers impacted subsequent teacher beliefs as a personalized form of video-based reflective coaching was facili tated via a video annotation tool. By qualitatively portraying the complex relationship between a single teacher’s beliefs andhis classroom practice the study’s findings signal the need for studies that explore nuanced ways of supporting a transitioning teacher’s self-efficacy. With the field striving to uncover supports that impact subsequent teacher actions in the classroom, the study also pro vides suggestions for helping teachers contend with the challenges that arise while instituting the difficult-to-adapt teaching strategies that accompany the Next Generation Science Standards. |

| Abstrak | : | This article investigates the problem whether the difference between two parametric models m1, m2 describing the relation between a response variable and several covariates in two different groups is practically irrelevant, such that inference can be performed on the basis of the pooled sample. Statistical methodology is developed to test the hypotheses H0: d(m1, m2) ? ? versus H1: d(m1, m2) < ? to demonstrate equivalence between the two regression curves m1, m2 for a prespecified threshold ?, where d denotes a distance measuring the distance between m1 and m2. Our approach is based on the asymptotic properties of a suitable estimator ?????(ˆ????1,ˆ????2) of this distance. To improve the approximation of the nominal level for small sample sizes, a bootstrap test is developed, which addresses the specific form of the interval hypotheses. In particular, data have to be generated under the null hypothesis, which implicitly defines a manifold for the parameter vector. The results are illustrated by means of a simulation study and a data example. It is demonstrated that the new methods substantially improve currently available approaches with respect to power and approximation of the nominal level. |

| Abstrak | : | Mentoring, as one of the formal teacher leadership roles, creates a space for teachers to display their leadership potential as it indirectly brings value to the school community (Ensher & Murphy, 2006). The purpose of this qualitative case study is to examine mentor teachers’ perceptions whether they transfer their evolving mentoring skills into other leadership practices. The participants entail three experienced secondary physics and chemistry teachers [Master Teaching Fellows (MTFs)]. The data obtained from interviews with the MTFs and archi val data from the leadership program are analyzed using multiple coding methods (In Vivo, Thematic Analysis, and Theoretical Coding Saldaña, 2013). It is found that mentoring is a vital component of teacher leader development, which is a continual process of capacity building requiring time and patience. The results provide practical suggestions to mentors and PD developers for fruitful formation of effective mentoring and leading skills to be influencing other tea chers. The complexity of mentoring/leadership work require support of a community to achieve desired outcomes. Thus, providing struc tured training for mentors should be an integral part of school professional development. |

Group-Linear Empirical Bayes Estimates for a Heteroscedastic Normal Mean

| Abstrak | : | The problem of estimating the mean of a normal vector with known but unequal variances introduces substantial difficulties that impair the adequacy of traditional empirical Bayes estimators. By taking a different approach that treats the known variances as part of the random observations, we restore symmetry and thus the effectiveness of such methods. We suggest a group-linear empirical Bayes estimator, which collects observations with similar variances and applies a spherically symmetric estimator to each group separately. The proposed estimator is motivated by a new oracle rule which is stronger than the best linear rule, and thus provides a more ambitious benchmark than that considered in the previous literature. Our estimator asymptotically achieves the new oracle risk (under appropriate conditions) and at the same time is minimax. The group-linear estimator is particularly advantageous in situations where the true means and observed variances are empirically dependent. To demonstrate the merits of the proposed methods in real applications, we analyze the baseball data used by Brown (Citation2008), where the group-linear methods achieved the prediction error of the best nonparametric estimates that have been applied to the dataset, and significantly lower error than other parametric and semiparametric empirical Bayes estimators. |
