Teaching and learning speaking skills should be able to engage students in a creative process. Students have to be able to speak in front of the class, create a dialogue, tell a story, and produce the language creatively. The teaching and learning of the speaking skill focusing on story telling ability can work well when supported by the appropriate choice of teaching method. This study attempts to: 1) identify the list of things needed by teachers of primary schools to teach Bahasa Indonesia in fun and creative ways, 2) design a prototype of suggestopedia based storytelling learning model to teach Bahasa Indonesia in primary schools, 3) develop the prototype into a suggestopedia based storytelling learning model to teach Bahasa Indonesia in primary schools, 4) determine the effectiveness of the application of suggestopedia based storytelling learning model to teach Bahasa Indonesia in primary schools. This research is a model development study based on the procedures by Borg and Gall. This study demonstrated that a teaching model is created through the following steps: 1) identifying and analyzing the needs of the students and teachers, 2) designing and evaluating the model, 3) developing and testing the model. The effectiveness test showed a significant increase of 3.03 or 8.11% in the experimental group's mean score, from 18.94 in the pretest to 21.97 in the posttest. Meanwhile, the control group only experienced a 2.51 or 6.36% in the mean score, from 18.50 in the pretest to 21.05 in the posttest. Hence, it can be concluded that the students' story telling skill in the experiment class using the teaching method developed in this study was higher than in the control class. The result implied that the teaching model prototype can be further developed to increase the primary students' story telling skill in Salatiga.
