**3. Conclusion**

Based on the results obtained, the following conclusions can be formulated

	- a.The syntax consists of four stages, namely *preparing (P),* doing *(D),* checking *(C), and* assessing *&* following-up *(A).*
	- b.Named PDCA metacognitive learning strategies.
	- c.Based on metacognition theory, meaningful learning theory, constructionism theory, active learning theory, *transfer of learning theory,* mastery learning *theory, and* self-regulated learning theory*.*
	- d.Aims to improve metacognitive abilities, build scientific explanations, learning achievement, and higher-order thinking of students.
	- a.Have met the requirements of content validity (relevance) and construct validity (consistency) with very valid categories.
	- b.Have met the practicality requirements, namely the stages of the SM-PDCA learning strategy can be implemented as a whole by lecturers with very high categories.
	- a.All students think that the tasks given before learning help prepare themselves for learning
	- b.Students feel they can learn well through activities to prepare themselves to learn, choose and plan ways of learning, be actively involved in learning, monitor understanding, and evaluate their learning,
	- c.Most (93%) students stated that the learning steps experienced made it possible to understand the material well,
	- d.All students feel that the lecturer provides an opportunity to monitor their understanding, and
	- e.Most (96%) students stated that the quiz given at the end of the lesson helped to find out the understanding of the material that had been learned.
