These sections of the textbook are focused on various aspects of identifying the language learning level of students and strategies for developing their language skills.
"Stages of Language Acquisition" categorizes the stages of language learning, gives some qualitative indications for recognizing whether a student is at a given stage, and gives in list form broad strategies for dealing with students at each level. It also introduces the California English Language Development Test (CELDT) and compares its scoring ranges to some other English language proficiency measurements. These pages seem like a nice reference for measuring language proficiency, but the list of strategies seems pretty low on details for actually dealing with a given student or group of students.
"Oral Language Through Content" discusses some strategies for assisting English learners in particular subject areas (math, science, and social studies). This section seemed especially useful for single subject teachers like myself, and I'm fairly certain I will be going back to this reading for hints when I begin my tutoring.
"OLE Guide" gives a brief overview of the OLE Project, which was aimed primarily at identifying optimal learning environments for Latino students - which the research identified as a teaching method called Holistic-Constructivism. This methodology was explained through a set of key principles, and also contrasted somewhat with a teaching method they called Reductionism. Unfortunately, this section left me unconvinced of their central argument that Holistic-Constructivism is superior since no supporting evidence was supplied (although the principals seem reasonable enough). I might consider this as worthy of further study in the future (maybe).
"Natural Writing Development" gives an interesting example of the
stages children typically go through on the way to learning to
write. Although this reading was entertaining, it didn't seem all
that relevant to a single subject teacher like myself who is likely to
be dealing with students who already know how to write at least a
little bit in one language. It was entertaining though.
Overall these readings seem very high level - which is probably to
be expected at this point of study. I would say that the readings
make me feel more cognizant of the amount of material to be studied in
the future rather than saying that these readings make me feel
significantly better prepared for dealing with English learning
students.
