[beta]-lactamases are hydrolytic enzymes that inactivate the [beta]-lactam ring of antibiotics such as penicillins and cephalosporins. The major diversity of studies carried out until now have mainly focused on the characterization of [beta]-lactamases recovered among clinical isolates of Gram-positive staphylococci and Gram-negative…

To determine whether having a program is sufficient one must first define what is meant by "program." If by program one refers to the pullout program in the elementary school, or the afterschool enrichment program in the middle school, or the Advanced Placement program in the high school, or the hockey program, then certainly having a "program" is…

This paper focuses on the broad outcomes of a research project which aimed to analyse and model student teachers' learning in the online components of an initial teacher education course. It begins with discussion of the methodological approach adopted for the case study, which combined conventional data gathering techniques with those which are…

The authors demonstrate how to tailor curriculum to support the varied interests, abilities, and talents of the children in a kindergarten class. Through words and photographs, they describe an in-depth study of rocks and sand, a topic of great interest to the children. The teachers posed open-ended questions that fostered high-level discussions.…

This paper highlights my experiences as World Citizenship teacher at a public school in the Netherlands, comprising a student population of second generation immigrants with a Turkish background. It shows how the concept and course of world citizenship has evolved since its inception three years ago. The paper also reflects what we, as teachers…

The purpose of this study was to examine the collegial coaching model of staff development used by 8 English teachers at one Georgia high school. The 8 teachers worked in 4 groups of 2 to develop curriculum, design lessons, and create assessments for one grade level of students. The theoretical foundation for the collegial coaching model dates…

Traditional school science instruction has been largely unsuccessful in reaching diverse student groups and students from, in particular, underrepresented backgrounds. This paper presents a case study of an urban, dual-language middle school classroom in which the teacher used an alternative instructional approach, involving her students in an…

Preparing all students to succeed in today's increasingly global economy and complex world requires a shift from a teacher-centric culture to learner-centered instruction, according to a new report from the Alliance for Excellent Education. This report examines the characteristics of learner-centered instruction and the support that educators and…

In countries where higher education has largely been a state function, conservative bureaucracies are viewed as impediments to necessary development and change. Virtually everywhere, voices are raised to demand necessary reforms yet, in spite of these apparently common challenges, it remains true that policy-related education issues are framed by…

Policymakers and industry leaders are calling for a 21st century education that is more interdisciplinary in nature, including the ability to solve problems and think creatively. Traditional teaching practices that present subjects as separate and distinct disciplines do not encourage students to make connections between subjects in school and in…

This study was conducted to describe a high school engineering curriculum, identify teaching strategies used to increase math and science literacy, and discover challenges and constraints that occur during its development and delivery, as well as what strategies are used to overcome these obstacles. Semi-structured interviews were conducted with…

Young learners today are not growing up at the foot of the family radio or spending a good portion of their childhood glued to the television while Sesame Street and Mr. Rogers disseminate information in a constant stream as did previous generations. Rather, this generation of young learners continues to spend many out-of-school hours in a digital…

We designed and implemented curriculum intended to be used by students in an algebra-based introductory physics laboratory course. Our curricular goal was to foster, through observations in the lab, a coherent framework in students' understanding of general principles presented in the introductory mechanics course, while addressing known student…

The purpose of this study was to discover and compare perceptions of three different groups of Indiana elementary educators concerning the importance of areas of the principal's literacy knowledge base, as well as responsibility for and use of this knowledge by principals to adequately support effective research-based literacy instruction. The…

"Streaming" for mathematics remains a contentious issue and particular forms of the practice have been considered inequitable. In the study reported here, the focus was on the extent to which streaming is used for mathematics at years 7-10 in Victorian secondary schools. Also of interest were the forms of streaming adopted and the…
