Types of fragment teaching

Judging from the teaching content, fragment teaching can be divided into two kinds: excerpts and topics. Selective course selection is to select some fragments from the teaching materials for teaching, and the teacher determines the teaching objectives according to the selective course selection, designs the teaching plan and then implements classroom teaching. Topic category is to extract a topic (or a knowledge point, ability point, or a teaching link) from a certain class for the teacher to teach, and the teacher aims to teach. Zhu Ziqing's Moonlight on the Lotus Pond belongs to the excerpt category if the fourth and fifth paragraphs of the text are designated as fragment teaching. If teachers are required to guide students to learn the "synaesthesia" method in the text, it is the topic fragment teaching. For another example, the reading part of Unit 1 of Book 2 of senior high school English belongs to the excerpt category if the first natural paragraph in the text is designated for teaching; If teachers are required to guide students to learn the difference between "image" and "possibility" and "probably" in this class, it is thematic fragment teaching.

From the perspective of teaching scenes, fragment teaching can be divided into real environment and virtual environment. The fragment teaching based on reality provides a real classroom for teachers, and teachers can face students to teach. Virtual reality can only simulate teaching in front of judges or teachers who participate in teaching and research activities. Because the virtual scene fragment teaching is not limited by time and space, it is easy to operate. Although it has the disadvantages of being divorced from the students' main body, it is actually used more frequently.

From the source of topic selection, fragment teaching can be divided into two types: self-determination and other-determination. Self-shaping is the content of segment teaching that teachers choose by themselves; Others (experts, judges, organizers) specify the topic, and the teacher teaches in sections as required. Teaching and research activities mostly adopt self-defined segment teaching, and making full preparations in advance is conducive to carrying out teaching and research activities and showing teachers' elegant demeanor. Competition activities and evaluation work mostly use other stereotyped fragment teaching, temporary lottery, limited on-site lesson preparation, taking turns in class, etc., to test teachers' quality and teaching level, which can objectively judge their advantages and disadvantages.
