    To date, little literature has been published on how an alternative undergraduate teacher preparation program infuses mobile devices such as the iPad and its applications, model classrooms, and a high-tech computer lab to prepare teacher candidates. Preparing teacher candidates to generalize technological skills is most effective when it is hands on, using the varied devices and support available to them. Meaningful instruction, application and maintenance of technological usage is the key to 21st century teaching and learning but it will not occur without a designed plan of action or model. This article focuses on the prominence of the use of iPads for teacher candidates in higher education and its potential impact on the learning of students with varying backgrounds and abilities in public schools. Further, it provides conceptual, systematic, comprehensive, and ready-to-use three phases of an existing one-to-one iPad initiative model at a southeast institution of higher education in the United States of America.

    OBJECTIVES: Our study aimed to systematically assess and report the methodological quality used in epidemiological systematic reviews (SRs) and meta-analysis (MA) of pathogen genotypes/genogroups. STUDY DESIGN AND SETTING: Nine electronic databases and manual search of reference lists were used to identify relevant studies. The method types were divided into three groups: 1) with weighted pooling analysis (which we call MA), (2) unweighted analysis of the study-level measures (which we call summary statistics), and (3) without any data pooling (which we call SR only). Characteristics were evaluated using Assessment of Multiple Systematic Reviews (AMSTAR), Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA), and Risk Of Bias In Systematic reviews (ROBIS) tools. The protocol was registered in PROSPERO with CRD42017078146. RESULTS: Among 36 included articles, 5 (14%) studies conducted SR only, 16 (44%) performed MA, and 15 (42%) used summary statistics. The univariable and multivariable linear regression of AMSTAR and PRISMA scores showed that MA had higher quality compared with those with summary statistics. The SR only and summary statistics groups had approximately equal scores among three scales of AMSTAR, PRISMA, and ROBIS. The methodological quality of epidemiological studies has improved from 1999 to 2017. CONCLUSION: Despite the frequent use of unweighted summary statistics, MA remains the most suitable method for reaching rational conclusions in epidemiological studies of pathogen genotypes/genogroups
