The aim of the research reported in this article was to develop a reliable graphic organiser-based argumentation learning (GOAL) model with valid content and constructs. The model can be used to improve the self-efficacy and ability to argue of chemistry teacher candidates. The GOAL model consists of six phases. These are: 1)explaining the objectives and identifying the chemical problems based on the Internet of Things (IoT); 2) modellinggraphic organiser-based chemical arguments; 3) investigating chemical problems; 4) presenting chemical arguments; 5)transforming chemical arguments through writing; and 6) examining the understanding of argument-based chemistryand providing feedback. Quality data were obtained through focus group discussion (FGD). The GOAL model quality analysis used average validity scores, the inter-rater correlation coefficient (ICC) and Cronbach's alpha coefficient. The results showed that the GOAL model content and constructs are valid and the model is reliable. Therefore, the GOAL model is of high quality. © 2018 WIETE.
