This toolkit, developed by Regional Educational Laboratory (REL) Central in collaboration with York Public Schools in Nebraska, provides a process and tools to help teachers use data from their classroom assessments to evaluate promising practices. The toolkit provides teachers with guidance on how to deliberately apply and study one classroom…

In an effort to achieve high success in knowledge and technique acquisition as a whole, a biochemistry and molecular biology experiment was established for high-grade biotechnology specialty students after they had studied essential theory and received proper technique training. The experiment was based on cloning and expression of alkaline…

This article summarizes a dissertation study designed to determine the effectiveness of instructional interventions that focus on proofreading and editing skills of first-year college students enrolled in business communication courses. The study used a pretest-posttest quasiexperimental control group design and collected data from 56 participants…

Lexical items, because they are language specific forms are undoubtedly one of the most difficult tasks in learning a second language. Phrasal verbs perhaps further exacerbate this difficult task since the meaning of already known verbs changes drastically when combined with different particles.

Infinity has contradictions arising from its nature. Since mind is actually adapted to finite realities attained by behaviors in space and time, when one starts to deal with real infinity, contradictions will arise. In particular, Cantorian Set Theory, for it involves the notion of "equivalence of a set to one of its proper subsets," causes…

In this study, the implementation effects of a staff development program on cooperative learning (CL) for Dutch elementary school teachers were studied. A pre-test-post-test non-equivalent control group design was used to investigate program effects on the instructional behaviours of teachers. Based on observations of teacher behaviour during…

Students have continued to perform poorly in KCSE examinations in certain mathematics topics taught in secondary schools in Kenya. One such topic is commercial arithmetic. Successful teaching of mathematics depends partly on correct use of teaching methods in classroom settings. This study sought to examine how the use of advance organisers during…

The major advantage of STS is the kind of teaching it allows and demands. Twelve middle school teachers who were enthused with STS teaching selected two sections for a research study. One section was the experimental STS section; the other followed the course syllabus and textbook closely. The major findings indicate the advantages for STS as a…

Researchers in the field of bioinformatics have developed a number of analytical programs and databases that are increasingly important for advancing biological research. Because bioinformatics programs are used to analyze, visualize, and/or compare biological data, it is likely that the use of these programs will have a positive impact on biology…
