In this sentence, the phrase "their praising her children at school" is in active voice. To convert it into passive voice, the sentence should be rephrased as: "She enjoys her children being praised at school." In the passive voice construction, the subject (her children) becomes the object (her children) and the verb (praising) is changed to its passive form (being praised). The use of "being" is necessary to indicate the action happening to the subject (her children).
