A review of learning analytics opportunities and challenges for K-12 education.

Use of learning analytics to improve educational outcomes is a growing area of research. While learning analytics research has been more prevalent in higher education contexts, this study presents findings from a qualitative metasynthesis of 47 research publications related to opportunities and challenges relevant to learning analytics design, implementation, and research at the PK-12 level. Our findings indicate that, while many see the educational benefits of learning analytics (e.

Differential NRAMP1gene's D543N genotype frequency: Increased risk of contracting tuberculosis among Venezuelan populations.

NRAMP1 and VDR gene polymorphisms have been variably associated with susceptibility to tuberculosis (TB) amongst populations having different genetic background. NRAMP1 and VDR gene variants' association with susceptibility to active infection by Mycobacterium tuberculosis (Mtb) was analyzed in the Warao Amerindian population, an ethnic population from Venezuela's Orinoco delta region. Genomic DNA was extracted from individuals with and without TB to evaluate genetic polymorphism by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

Teachers' instructional responses to the COVID-19 pandemic.

In response to the COVID-19 pandemic, schools transitioned to Emergency Remote Teaching (ERT). In May 2020, as part of an existing study of flipped Algebra instruction, we interviewed eleven Missouri teachers to understand how their instruction changed as they moved to ERT. Drawing on practical rationality, we found the pandemic led to a breach of norms (assigning grades, synchronous meeting times, delivering new content, and students' completion of work).

Diagnostic Potential of the Serological Response to Synthetic Peptides from Antigens for Discrimination Between Active and Latent Tuberculosis Infections.

Diagnosis and treatment of active tuberculosis (ATB) as well as latent tuberculosis infection (LTBI) are required for effective tuberculosis (TB) control, especially in TB endemic area. The usefulness of conventional tests to distinguish between ATB and LTBI has remained challenging. The present study was aimed to demonstrate the usefulness of the serological response to synthetic peptides from () antigens for discrimination between ATB and LTBI in Warao Amerindians.
