The udu is a traditional Nigerian percussion instrument that can be thought of as a Helmholtz resonator with two apertures. We use a simple two-particle mechanical analogue to study the behaviour of such a resonator and find that the model describes quite well the main features of udu acoustics.

There is a knowledge gap in best practices for incorporating performance arts into science instructions. The study focused on the design and implementation of the Performance Arts Enhanced 3-Stage Instructional Model (PAEIM), which incorporated drama, dance and music. The PAEIM was implemented in mixed factorial quasi-experimental research during…

Purpose: This study reports on the outcome of an investigative inquiry approach - Model Based Inquiry (MBI) on achievement and critical thinking of college pre-service chemistry teachers. Methodology: Anchored on Constructivism, the study employed quasi experimental (nonequivalent control group) design. A total of 174 level 200 college pre-service…

This study was designed to investigate the Effect of Polya Problem-Solving Model on Senior School Students' Performance in Current Electricity. It was a quasi experimental study of non- randomized, non equivalent pre-test post-test control group design. Three research questions were answered and corresponding three research hypotheses were tested…

Proposes a model to explain secondary students' achievement in chemistry that uses the following predictor variables: students' attitude towards chemistry, understanding of science, scientific attitude, traditional cosmological world-view, cognitive style, and teachers' attitude towards the teaching of chemistry and understanding of science.…

Discussion of school effectiveness, achievement outcomes, and sociocultural influences focuses on a study of Nigerian high school students that was conducted to determine whether or not instruction based on a sociocultural model could significantly alter students' attitudes toward learning and achievement in science.
