Uses photomicrography and time-lapse sequences to reveal the research technique of nuclear transplantation. Shows how nuclei are transplanted from donor body cells into activated eggs.
A high school boy who is having trouble understanding poetry learns that he should find out about the poet's background, discover what experience the poet is sharing, and watch for such devices as rhythm, rhyme, and alliteration. Includes examples from many poets' works.
Presents a second lesson at the "Presentation Stage" of color work--the pronunciation area. Continues to discuss this well-known system for practicing the pronunciation of speech sounds, in isolation and in combination--"parts" later to be applied to "wholes".
Presents an integrative device for the general teaching (as contrasted with the specific speech lesson) of language and speech. Describes the entire pattern as well as attempting a speech correction. Explains the GLGSP framework for making a learning situation for language or speech or both out of every communication between pupil and adult.
Continues to describe and illustrate the speech model used for explaining both the learning of speech skills and the teaching seen in the entire 42-film series. Follows Face A from "Imitation Stage" to "Production Stage" (where a speech skill is habituated) and finally to the "Automatic Production Stage."
Continues work on the first step of learning "SH", blunting the tongue, at the "Imitation Stage." Shows the pupil achieving a better approximation of pulling the tip into the body of the tongue, and finally achieving correct blunting by keeping the tongue blunted and forward.
Depicts a second pupil beginning to learn "SH" through in-depth teaching, starting with Step 1--blunting--at Face A of the speech model. Examines the pupil's blunting error (pulling the whole tongue back) and his first approximate correction of the error, achieved through shaping.
Describes the criteria for choosing a sound for in-depth teaching. Provides an assessment of a pupil's automatic production of "SH" in words and syllables. Shows the teacher demonstrating the formation and development of "SH" to the pupil. Outlines the steps in learning "SH": 1) Blunt, 2) Close, and 3) Blow.
Provides an orientation to the entire series of 42 films, including descriptions and illustrations of purpose; content; teaching approaches (synthetic/analytic and multisensory); techniques of verbalizaton; and a structure for teaching speech in general situations, as well as specific speech lessons.
Continues in-depth work on the "SH" sound, with tongue blunting on face A of the speech model. Shows kinesthetic practice on blunting. The pupil has reached the "Production Stage" of tongue blunting and is ready to learn the second step of "SH": closing the mouth to the right degree while maintaining the blunted tongue. Progresses through Step 2 on face A of the speech model, consisting of the "Presentation Stage," "Imitation Stage," and "Production Stage." Presents a teacher evaluation of the pupil's errors at Step 2.
Concludes the description and illustration of the speech model used for explaining both the learning of speech skills and the teaching seen in the entire 42-film series. Shows the progressions of learning a speech skill through the three faces of the model (Faces B and C are for generalizing from Face A).
Describes and illustrates a speech model used for explaining both the learning of speech skills and the teaching seen in the entire 42-film series. Demonstrates Face A of the model through the "Presentation and Imitation Stages" including a demonstration of shaping.
Begins the in-depth teaching of "SH" by teaching the first step: learning to blunt the tongue. Follows the learning process through the "Presentation Stage" to the "Imitation Stage," after the teacher's evaluation of the pupil's main error in blunting. Demonstrates two teaching devices.
Examines the third step in producing "SH" in isolation: blowing air across the high blunted tongue. Progresses from the "Presentation Stage" through the "Imitation Stage" to the "Production Stage" using two teaching devices.
Demonstrates materials which aid in teaching speech relative to voiced-voiceless-nasal distinction, tongue shape, lip shape, self-monitoring, cleanliness, and stimulus and motivation. Suggests how to procure the aids shown in the Speech Kit films.
Discusses Garrod's work on inborn errors in the metabolism of alcapton and melanin. Shows how chemical pathways in metabolism can be worked out using genetic defects as tools. Discusses the metabolic diseases phenylketonuria and galactosemia and points out that medical treatment causes the retention, and therefore the build-up of defective genes in the population. Presents the one geneone enzyme hypothesis and describes the procedure for testing the hypothesis in question with mutants of Neurospora requiring Vitamin B1 (thiamin). Lecture given by Dr. G. W. Beadle.
Demonstrates the operation and care of the RCA 400 16mm sound projector. Presents detailed instructions for setting up the Junior and Senior models and for initial adjustment, threading, operating, rewinding, and packing up projectors. Demonstrates the cleaning and lubrication procedures for the two projectors and the replacement of tubes in the amplifier section.
