An Instrument for Evaluating Experimental Research Reports was developed after synthesis of the suggestions of experts. In two studies of reliability with articles from the field of elementary mathematics education and raters from that field and from educational psychology, coefficients of Inter-rater agreement of .01 and .04 resulted, while .77 and .58 were the corresponding coefficients of Intra-class reliability. The Instrument is suggested for use not only In evaluation, but also In planning and developing research studies.
