I suggest removing "In Addressing the Developmental Needs in" as it is redundant and can be streamlined. Additionally, changing "Develop" to "Developing" accurately reflects the ongoing nature of your research.

A concise and clear title would be:

Developing Capacity Building Activities to Improve the Work Performance of Master Teachers in Bislig City Division

Alternatively, you could explore other verbs synonymous with "improve" to enrich the title, such as "Boost", "Enhance", or "Augment"

You could also use the General Formula of :

[Outcome] [Method] [Study] [Topic] [Sample]

• Outcome: The result or goal of the research.
• Method: The approach or strategy used.
• Study: The research itself.
• Topic: The main subject of the research.
• Sample: The participants or subjects involved.

Following the suggested formula, here's the breakdown of the title I suggested:

• Outcome: Developing Capacity Building Activities
• Method: Not explicitly stated
• Study: To Enhance
• Topic: Work Performance
• Sample: Master Teachers in Bislig City Division
