求翻译：教学单词的时候，采用了一小组同学来共同朗读一个单词的形式。 小学生一般都好胜心强，喜欢表现自己，还特别容易激动。但由于自控能力较差，注意力容易分散，影响了课堂教学效果。引入竞争机制，能激发学生的有意注意。课堂上搞小组纪律竞赛，学生必然为集体荣誉而增强自控能力，上课能专心听讲、用心思考，也会自觉地监督提醒其他同学遵守纪律。穿插一些单词合作拼写竞赛，由于拼一个单词需全体参与，势必每个学生都要认真听讲才行，否则竞赛时，出错的一个学生就会受到同组学生的排斥和不满。所以竞争机制的导入也提高了全体学生的学习积极性。是什么意思？

When teaching words, employs a small group of students to read together in the form of a Word. Pupils generally combative heart strong, like to show themselves, particular excitable. But due to poor self-control, attention is easier to disperse, the impact of the classroom teaching effect. Introducing the competition mechanism, can stimulate students ' attention. Group discipline in the classroom competition, students must enhance self-control for the collective honor, to listen in class thinking, intentions, also consciously discipline supervision and remind the other classmates. Spelling contests interspersed with some words cooperation, as spelling a Word takes all participation is bound to each of the students are listening intently to a row or when race, faulted a student will be subjected to the same group of students of exclusion and discontent. So the competition mechanism of import will improve all students ' enthusiasm.
