Classic Express Research project by Ilona Sie Dhian Ho

In a combined qualitative and quantitative research the influence of storytelling in concerts for children is analyzed. In a controlled setting, The Classic Express (mobile concert hall), groups of schoolchildren attend either a concert with or a concert without storytelling. The groups, similar in socio- economic background and age, are compared. In a quantitative research the involved listening, the felt emotional intensity, the interest in classical music and the interest in actively playing an instrument, will be measured. For quantification new grading systems are developed by scientists and musicians in a collaborative process. In a qualitative research on the influence of storytelling the focus is on children with severe learning disorders. The emotional responses of these children in concerts with and without storyelling, and in combination with participatory elements (moving, gestures) are observed by teachers and caretakers, They compare their observations in the concert to the normal behaviour of their pupils. Both Interviews with the teachers and their grading of arousal, attention and emotional levels in the concert will provide data that will be analyzed by the reserachers. This research is the first study of The Classic Expression Research Group, a group of researchers from the Royal Conservatoire and Leiden University, collaborating to provide new insights on the impact of presentation techniques in classical concerts.

Reliability of coders

Intra class correlation

To calculate the reliability of the coders in the Classic Expression research group their Intra Class Correlation (ICC) is calculated.

This is to know if coders score consistent and similar using a coding construct.

It is not an absolute number, but a percentage, based on the relative similarity between coders.

It means for example that the highest score of coder 1 is the same child as the highest score of coder 2.

ICC is poor/good if:

-many scores are (not) the same

-the differences are smaller/bigger

-the order in grading is different/similar

The coders of the Classic Expression coding group that have passed the last test in August 2021 have rates between 82 and 92.

These are considered good to excellent by the guidelines for interpretation of ICC by Cicchetti and Koo and Li.

Cicchetti (1994):

•Less than 0.40—poor.

•Between 0.40 and 0.59—fair.

•Between 0.60 and 0.74—good.

•Between 0.75 and 1.00—excellent

Koo and Li (2016):

•below 0.50: poor

•between 0.50 and 0.75: moderate

•between 0.75 and 0.90: good

•above 0.90: excellent

One coder did not yet pass the test yet and will not code in the research.
