Classroom application of using visual stimuli in learning dynamics and pitch
Listening is a common activity in music lessons. It is difficult for teachers to know whether students are learning by listening. In this study, visual stimuli include imagery, metaphor, and symbols, were introduced to students in the experimental group to learn dynamics and pitch. A control group received the same lessons without any visual stimuli. Both groups received the same tests, pre-test and post-test, after the two lessons. Tests were divided into two parts including choosing the correct dynamic changes and distinguishing higher or lower pitch for the melody. Results showed the experimental group had improved more than the control group. The change of the experimental group in rela…
Evaluation of appendicitis risk prediction models in adults with suspected appendicitis.
Background Appendicitis is the most common general surgical emergency worldwide, but its diagnosis remains challenging. The aim of this study was to determine whether existing risk prediction models can reliably identify patients presenting to hospital in the UK with acute right iliac fossa (RIF) pain who are at low risk of appendicitis. Methods A systematic search was completed to identify all existing appendicitis risk prediction models. Models were validated using UK data from an international prospective cohort study that captured consecutive patients aged 16–45 years presenting to hospital with acute RIF in March to June 2017. The main outcome was best achievable model specificity (pro…
