In this research, the in-service Liberal Studies teachers are addressed to raise concerns about the discrepancies between perceptions and practices. As Liberal Studies is a newly formed subject in Hong Kong, limited research on the teachers’ perceptions of inquiry-based learning is conduced. Therefore, this research enriches teachers’ understanding on their own interpretations on the concept of inquiry-based learning and allows them to carry out evaluation on their practices of inquiry-based learning in classroom. Besides, this research serves to point out and clarify some of the misconceptions about inquiry-based learning, which promotes teachers’ reflection on their own perceptions and practices for the purpose of better teaching effectiveness and efficiency. Furthermore, according to this research, it is evident that there is close relationship between perceptions and practices within teachers. It is identified that there are a number of factors which have great impact towards the implementation of inquiry-based learning. This raises educators’ concerns on these factors when considering the use of inquiry-based learning in classroom.
For future study, it is recommended for a longitudinal investigation on reviewing the changes of teachers’ perceptions and practices of inquiry-based learning since the establishment and implementation of NSS Liberal Studies curriculum. Furthermore, as inquiry-based learning originates in other foreign countries, the study can make comparisons on the interpretations of inquiry-based learning of different countries. In addition, more investigation can be conducted to explore the factors which significantly affect the implementation of inquiry-based learning.

6.3 Conclusion
To conclude, the in-service teachers in Hong Kong generally have basic understanding on the concept of inquiry-based learning. The practices of inquiry-based learning in Liberal Studies are demonstrated in lessons even though teachers are unaware on their underlying values.
Also, it is concluded that there are some discrepancies found between perceptions and practices. More importantly, perceptions and practices are closely linked and affected with each other. This study thus provides an insight for teachers to be aware and reflexive on the relationship between perceptions and practices.
On the other hand, the research reveals that there are a number of factors concerning about the student’ learning motivation, authority of teachers , teaching of different issues and modules, learning environment as well as examination culture, which pose significant impact towards the implementation of inquiry based learning in Liberal Studies.
Lastly, the research can be concluded by the arguments from Carlina Rinaldi(2006), which is meaningful for every educator to address:
“Learning does not proceed in a linear way, determined and deterministic, by progressive and predictable stages, but rather is constructed through advances, standstills, and retreats that take many directions. The construction of knowledge is a group process. Each individual is nurtured by the hypotheses and theories of others, and by conflicts with others, and advances by co-constructing pieces of knowledge with others through a process of confirmation and disagreement. Above all, the conflicts and disturbance force us to constantly revise our interpretive model and theories on reality…theory
and practice should be in dialogue, two languages expressing our effort to understand the meaning of life. When you think, it’s practice; and when you practice, it’s theory.”
