This study was aimed to identify the relationship between problem solving skills, metacognitive awareness, and mathematics achievement as well as to identify the role of metacognitive awareness as a  mediator. This study involved a total of 333 Form Four students from ten secondary schools in Malaysia. Data were collected using questionnaires, while information about mathematics achievement was provided by the school management. Data were analyzed using the Structural Equation Modeling (SEM) technique. Results indicated that all variables correlated significantly with each other, while path analysis revealed the mediation effect of metacognitive awareness between problem solving skills and mathematics achievement. The findings suggest the importance of problem solving skills in influencing secondary school students’ mathematics achievement through the development of metacognitive awareness.

The current study validates the structural model of cause-effect relationship in light of organizational citizenship behaviour as a consequence and its determinants as causes, which ultimately generates a generalizable public service model for the countries that need substantial organizational transformation in public service delivery. The determinants of organizational citizenship behavior by taking a look into the social and personal factors that either drive an individual’s behavior drawing from the social circumstances at the moment of time, or personal motivation and inner characteristics that force an individual to act in favor or against good citizenship. To test the proposed research framework, post-community Azerbaijan’s ASAN Service is considered as the case. For the identification and validation of potential factors affecting organizational citizenship behaviour, the selected variables are employed as constructs of the conceptual framework, through which survey is designed and administered to collect data from the country citizens with regards of gauging the impact of the determinants. A quantitative methodological approach is selected, where data is collected through convenient sampling technique, while it is analysed using the structural equation modelling technique, with emphasis on AMOS v.24 software to test the structural model. The results of the hypothesized relations reveal that behavioural intention and organizational identification are strongly related to organizational citizenship behaviour, followed by distributive justice, public service motivation, selfconcept and goal clarity being secondary major determinants. However, procedural justice is not significant in predicting organizational citizenship behaviour, while subjective norm and task interdependence are weakly related to it.
