Self-directed learning readiness and learning achievements of a flipped classroom model approach in research methods class: A quasi-experimental study.

Aim: This study sought to assess how the flipped classroom model of instruction affected self-directed learning readiness and learning outcomes among Nigerian nursing students enrolled in a research method class.

Background: Although the effectiveness of the flipped classroom model of instruction has been thoroughly and scientifically investigated in several fields, its potential to promote self-directed learning readiness and learning outcomes in a research method class has not yet been investigated.

Design: A quasi-experimental design was employed.

Sonographic estimation of gestational age from 20 to 40 weeks by fetal kidney lengths' measurements among pregnant women in Portharcourt, Nigeria.

Background: Ultrasonography has become an indispensible tool in the management of obstetric patients. Accurate determination of fetal gestational age (FGA) has posed great challenge to patient management as the accuracy of traditional biometric parameters decreases with advance in gestation age. Accuracy of fetal kidney length (FKL) in the determination of FGA at third trimester has been documented in other population.
