Bayesian Analysis of Semiparametric Hidden Markov Models With Latent Variables

In psychological, social, behavioral, and medical studies, hidden Markov models (HMMs) have been extensively applied to the simultaneous modeling of heterogeneous observation and hidden transition in the analysis of longitudinal data. However, the majority of the existing HMMs are developed in a parametric framework without latent variables. This study considers a novel semiparametric HMM, which comprises a semiparametric latent variable model to investigate the complex interrelationships among latent variables and a nonparametric transition model to examine the linear and nonlinear effects of potential predictors on hidden transition. The Bayesian P-splines approach and Markov chain Monte Carlo methods are developed to estimate the unknown, a Bayesian model comparison statistic, is employed to conduct model comparison. The empirical performance of the proposed methodology is evaluated through simulation studies. An application to a data set derived from the National Longitudinal Survey of Youth is presented.     

The effect of epistemic fidelity and accessibility on teaching with physical materials: A comparison of two models for teaching decimal numeration

Multi-base arithmetic blocks (MAB) are the most frequently used physical materials for teaching about decimal numbers, despite published reservations about their appropriateness. This paper presents an alternative, LAB (linear arithmetic blocks) and compares the two materials on the basis of epistemic fidelity and accessibility for students. Two teaching experiments involving 30 matched students indicated that LAB is considerably more accessible for students, and identify three contributing factors (LAB modeling number with length rather than volume, MAB incorporating an apparent dimensional shift and having prior use). Use of LAB was associated with more active engagement by students and deeper discussion. Epistemic fidelity is critical to facilitate teaching with the models, but we attribute the enhanced classroom environment to the greater accessibility of the LAB material. Further research is warranted, so that teaching of mathematics with physical materials can be improved. This revised version was published online in July 2006 with corrections to the Cover Date.

借鉴·整合·超越--数学教学模式运用的三重境界

数学教学模式的运用，在教师专业化成长进程中的作用不尽相同．数学教师从新手到专家大体上需经历以下3个阶段：首先要借鉴、学习、熟悉多种数学教学模式，掌握数学教学的基本规范；进而是根据具体的教学场景，发挥各种教学模式的优势，灵活运用模式，整合多种模式；最终是要超越模式，逐渐形成自己的教学风格，走向教学的自由，达到“无模式化”教学的最高境界。
