"One text he [Millner] resurrected was George Adler’s A Practical Grammar of the Latin Language (1858). This text sought to teach Latin through what he termed “a Serial and Oral method”. The way the text is utilised by Millner is similar to the Audio-Lingual method of the 1960s except explicit grammar instruction is also given. Millner argues that the method may not have been popular at the time because it required a teacher to conduct hours of question and response style drills which gradually introduced grammar and vocabulary.
The book comes in at over 1000 pages long but is comprehensive. Millner spent two years recording the exercises into an audio format where a student can run the drills from an audio player.
The audio course follows the textbook, but Millner adds material and expands on the paradigms: if a student wants to use the course along with the book, pre-reading a chapter quickly before listening would be helpful, as the audio course - especially for the grammatical sections, is not simply a read-aloud of the textbook.
The Dictata follow Adler's text pretty much as it was published, presented in Latin English Latin, the repetitions in Latin only.
Millner suggests the book be worked through whilst being supplemented with a large amount of easy extensive reading passages as well. Millner has also created playlists divided by level so that beginners looking for extensive reading or listening practice might find something from the archived books and get audio as well. Locke and Hamilton's interlinear readers are included in his collections. Like Conlon, he notes that traditional approaches do not contain enough actual reading practice and he advocates massive amounts of reading and listening as well as oral practice drills. "
