Background and Purpose: The role of collocation learning strategies is less of a concern as mediator. Although several correlation studies of bivariate factors have provided the relationship between the variables, many cannot answer the question of how the relationship exists. Also, a lot of studies have taken into account the variables of collocation learning strategies as mediator factors and have not illustrated clearly the relationship between independent variables (motivation) and dependent variables (collocation knowledge). As such, the aim of the present study is to identify the knowledge of Arabic collocation by taking several factors, namely; motivation and collocation learning strategies that have the potential to increase the knowledge of Arabic collocation in Malaysia. Methodology: In this study, a cross-sectional design was applied. Simple random sampling was used, where a total of 344 final year Arabic language students from eight public universities in Malaysia took part in the study by completing a set of tests and questionnaires. The data were analyzed using the Partial Least Squares Structural Equation Modeling (PLS-SEM) technique. Findings: The findings show there is a direct and indirect relationship between motivation variable, collocation learning strategies and collocation knowledge. In addition, the learning strategies factor also serves as a partial mediator. Contributions: This study suggests that collocation learning strategies play a role in the relationship between motivation and collocation knowledge in the context of Arabic language at higher education level in Malaysia.
