Résumé :

Literature at the secondary level has demonstrated a tight interconnectedness between one's beliefs about teaching and learning and one's instructional practices. Moreover, this research indicates that personal and contextual factors influence beliefs and that growth and changes in beliefs are most notable during the early years of one's teaching experience. Despite the substantial influence of teaching beliefs on educational decisions, very little research has been conducted at the post-secondary level in both characterizing and monitoring changes in beliefs over time of early-career faculty

Résumé :

In this era of instructional transformation of Science, Technology, Engineering, and Mathematics (STEM) courses at the postsecondary level in the United States, the focus has been on educating science faculty about evidence-based instructional practices, i.e. practices that have been empirically proven to enhance student learning outcomes. The literature on professional development at the secondary level has demonstrated a tight interconnectedness between ones’ beliefs about teaching and learning and one's instructional practices and the need to attend to faculty's beliefs when engaging them i

Life skills preparation for adulthood is a crucial, yet often overlooked concept in education. In schools across the United States, young adults graduate from high school with limited knowledge regarding how to navigate through the expectations of the real world. Although many educators feel teaching life skills in the classroom is necessary, the frustration of needing to adhere to state standards and lack of time often interferes with their implementation. This is unfortunate, as research indicates, “life skills education bridges the gap between basic functioning and capabilities. It strength

For a variety of reasons, the study and teaching of both United States history in general and the history of the Gilded Age and Progressive Era in particular should be thriving in Canada more than in other nations. Geographic proximity and shared language would advance this probability, even if the pervasive presence of American mass media did not.

Abstract. Atmospheric aerosols are a significant public health hazard and have substantial impacts on the climate. Secondary organic aerosols (SOAs) have been shown to phase separate into a highly viscous organic outer layer surrounding an aqueous core.

Résumé :

Teacher satisfaction is a key affective reaction to working conditions and an important predictor of teacher attrition. Teacher evaluation as a tool for measuring teacher quality has been one source of teacher stress in recent years in the United States. There is a growing body of evidence on how to evaluate teachers in ways which support their growth and development as practitioners. For this study, we inquired: What is the relationship between supportive teacher evaluation experiences and U.S. teachers’ overall job satisfaction? To answer this question, we employed a multilevel regression an

In this study, we examined the schooling process of newcomer students in secondary urban schools involving survey research with newcomers and other ELs (n=268). Additionally, we conducted focus groups with students (n=10) and educators (n=12). Through qualitative measures, we examined: (a) grade level placement, (b) content area placement, and (c) academic challenges confounded by L1 proficiency, previous academic experiences, and socio-cultural experiences among newcomers.

Résumé :

This study focused on inquiring into undergraduate chemistry professors’ efforts in North America to increase student motivation and interest in the subject and the feasibility of methods that connect students to real world applications and societal issues related to chemistry. A survey was distributed to chemistry instructors at post-secondary institutions across the United States and Canada asking about the usage of methods and tools to deliver content aiming at raising students’ perception of the relevance of learning chemistry (N = 124).

Résumé :

Nuclear magnetic resonance (NMR) spectroscopy is an essential analytical tool in chemistry, and the technique is routinely included as a topic across the undergraduate chemistry curriculum. As a result of NMR's importance, classroom instruction of this topic has received considerable attention in chemistry education research. However, little is known about instructors’ knowledge for teaching this topic. In order to better understand this knowledge, we investigated topic-specific pedagogical content knowledge in<sup>1</sup>H NMR spectroscopy among 20 chemistry teaching assistants at a large Mid

This study was triggered by the Teachers Sercice Commission (TSC) coming up with teachers performance appraisal strategies to appraise teachers and administrators in its employment, but the program has not fully realized the objective of evaluating teachers performance and initiate professional development. There has been a stiff resistance from teachers on the use of appraisal tool terming it as forced appraisal. The study, therefore, sought to establish whether there is a relationship between appraisal and reward/compensation, examine how setting of standards and targets influences teachers

Patient and hospital demographics were extracted from NIS. Peri-procedural complications were calculated using ICD-9-CM codes. Hierarchical multivariate regression models were formulated to assess predictors of in-hospital mortalit

Résumé :

The generation of secondary processing mill residues from wood processing facilities is extensive in the United States. Wood flour can be manufactured utilizing these residues and an important application of wood flour is as a filler in the wood–plastic composites (WPCs). Scientific research on wood flour production from mill residues is limited. One of the greatest costs involved in the supply chain of WPCs manufacturing is the transportation cost. Wood flour, constrained by low bulk densities, is commonly transported by truck trailers without attaining allowable weight limits. Because of thi
