Innovation of Let’s JizZle! and its effectiveness towards English vocabulary learning

The use of games in teaching especially in English Language Teaching (ELT) has become a norm among educators globally. The difficulties students’ face in acquiring spellings and definition of the words, extensive use of mother tongue, lack of dictionary skills and the pedagogical negligence in acknowledging students’ learning abilities in acquiring vocabulary have led to the innovation of Let’s JizZle! Hence, this paper described the process of designing and developing Let’s JizZle! as well as its effectiveness in teaching and learning vocabulary for both primary and secondary school learners of lower to intermediate proficiency. Game Based Learning (GBL) and differentiated instructions theory are the two main underpinning approaches in this innovation. Design and Development Research (DDR) was employed as the research design and ADDIE model was the research framework in developing Let’s JizZle!. The significant impacts towards vocabulary learning were proven through pre and post tests. Let’s JizZle! benefited the students to comprehend the vocabulary learnt as well as applying it in context besides acting as a teaching aid among teachers. It is the first jigsaw puzzle designed based on 21st century learning and CEFR textbooks for vocabulary learning especially for A2-B2 achievers. Let’s JizZle! has high commercialisation potentials.
