考题 共用题干 Teaching Math,Teaching AnxietyIn a new study about the way kids learn math in elementary school,the psychologists at the University of Chicago Sian Beilock and Susan Levine found a surprising relationship between what female teachers think and what female students learn:If a female teacher is uncomfortable with her own math skills,then her female students are more likely to believe that boys are better than girls at math.If these girls keep getting math-anxious female teachers in later grades,it may create a snowball effect on their math achievement said Levine. In other words,girls may end up learning math anxiety from their teachers. The study suggests that if these girls grow up believing that boys are better at math than girls are,then these girls may not do as well as they would have if they were more confident.Just as students find certain subjects to be difficult,teachers can find certain subjects to be difficult to learn一and teach. The subject of math can be particularly difficult for everyone. Researchers use the word“anxiety”to describe such feelings:anxiety is uneasiness or worry.The new study found that when a teacher has anxiety about math,that feeling can influence how her female students feel about math. The study involved 65 girls,52 boys and 17 first-and second-grade teachers in elementary schools in the Midwest. The students took math achievement tests at the beginning and end of the school year,and the researchers compared the scores.The researchers also gave the students tests to tell whether the students believed that a math superstar had to be a boy. Then the researchers turned to the teachers:To find out which teachers were anxious about math,the researchers asked the teachers how they felt at times when they came across math,such as when reading a sales receipt. A teacher who got nervous looking at the numbers on a sales receipt,for example,was probably anxious about math.Boys,on average,were unaffected by a teacher's anxiety. On average,girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus,on the test showing whether someone thought a math superstar had to be a boy,20 girls showed feeling that boys would be better at math一and all of these girls had been taught by female teachers who had math anxiety.“This is an interesting study,but the results need to be interpreted as preliminary and in need of replication with a larger sample,”said David Geary,a psychologist at the University of Missouri in Columbia.The sixth paragraph tells us that the research findings______.A:prove a strong link between female teachers'math anxiety and their female students' math achievementsB: show that male students are less likely to be affected by their math anxiety than female studentsC: provide strong evidence that math superstars are more likely to be males than femalesD: discover a strong link between teachers'math anxiety and their students'math achievements

考题 共用题干 Listening to BirdsongA male zebra finch chirps away to himself. Suddenly he notices a female bird nearby.He realizes he has an audience and immediately changes his song. Can the female tell the difference in his perfonnance?According to a new study,the female zebra finch knows.And she prefers the special trills he creates when he sings to her. A male zebra finch changes his song when singing to a female in ways that people can barely detect.But the female finch can tell the difference.Scientists had noticed slight variations in the songs of male zebra finches based on whether they were singing alone or whether there was a female(and potential mate)nearby.With an audience,the males sped up the pace of their songs and controlled the notes they used.For this study,researchers Sarah C .Woolley and Allison Doupe at the University of California,San Francisco decided to focus attention on the listening females,which have not been well studied in the past.In the study,Woolley and Doupe set up,a long cage with a sound speaker at each end.One broadcast the sound of a male zebra finch singing to himself,like someone singing in the shower.The other speaker broadcast a male performing for a female audience,as if he was giving a concert.Female birds were placed between the two speakers.Some of the birds had mates.Others didn't. The females shifted around a bit,and then most of them hopped over to sit beside just one speaker. All the birds that made a clear choice liked songs meant for a female audience,even if they'd never met the male.Mated females also had a chance to listen to two different performance songs,one from an unknown male,and one from their mate .They spent more time listening to the concert version of their mates' songs.This suggests that after a while,females learn to recognize-and prefer-the songs of their mates.Scientists then studied the brains of the females.They found certain areas of the brain perked up when the birds listened to the concert songs.These brain areas may be involved in recognizing and evaluating the songs,and storing the memories of them.This research deals with what's called directed communication,when the communicator,or sender,focuses the message for a specific audience.One example is the way moms speak to their babies. Mothers around the world use the same sort of high-pitched sing-song chatter,and the babies respond best to those sounds.Songbirds are one of the only other species known to learn their communication,in this case their songs. What is NOT true of directed communication?A: The sender of a message has a specific audience.B: Male zebra finches sing to female finches.C: Mothers talk to their babies.D: Male zebra finches sing to themselves.

考题 资料:Special needs students can not only learn from regular education teachers, but can participate in collaborative learning with mainstream students as well. Collaborative learning allows students to work together in groups to complete lessons and assignments. A number of educators with inclusion classrooms are realizing the benefits of collaborative learning and special needs students being placed in small group environments with regular education classmates. Collaborative learning allows students to converse with one another and brainstorm together in order to find solutions to problems or to complete an assignment. This type of learning allows students of varying ability levels to lend their individual strengths to the group as a whole, thereby encouraging an appreciation of diverse ideas and approaches to problem solving. Teachers can choose to implement several different types of collaborative learning strategies, depending on the needs of students and the focus of specific assignments. Examples of small-group collaborative learning methods are: 1) The Think-Pair-Share strategy, which involves each student in the group taking one minute to formulate a response to the teacher's question, then sharing individual findings with a partner. After collaborating in pairs, students can then share input with slightly larger groups or with the entire class. 2) The Simple Jigsaw strategy, which involves four-person teams splitting a teacher-assigned task into equal parts. Each student in the group acts as an "expert" on one section of the assignment and meets with corresponding "experts" in other groups for discussion and task mastering. Students then return to their initial teams to share their knowledge of the task with other members. 3) The Three-Step Interview strategy, through which students initially break into pairs and take turns interviewing one another about an assignment. Each pair of students then combine with another pair in order to enhance the discussion. 4) The Numbered Heads Together strategy, where each team member is assigned a number, then instructed to collaborate on a question. The teacher then calls a number randomly, and the student in each group who has that number acts as spokesperson in answering the question. Each student must be prepared for the possibility of having his or her number chosen. The benefits of collaborative learning and special needs students having the opportunity to engage in small group tasks can produce positive results in regard to classroom organization and management. Teachers who research tips on collaborative learning and implement the practice with students are likely to have a successful inclusion classroom. What are the benefits of collarborative learning for special needs students? ( )A.It helps special needs students think creatively B.It helps special needs students from all the attending students C.It helps special needs students learn varied ability from classmates D.It helps students work together on solving problems and assignments
