19．Call it the learning paradox：the more you struggle and even fail while you're trying to learn new information，the better you're likely to recall and apply that information later．
The learning paradox is at the heart of"productive failure，"a phenomenon identified by researcher Manu Kapur points out that while the model adopted by many teachers when introducing students to new knowledge providing lots of structure and guidance early on，until the students show that they can do it on their own makes intuitive sense，it may not be the best way to promote learning．Rather，it's better to let the learners wrestle with the material on their own for a while，refraining from giving them any assistance at the start．In a paper published recently，Kapur applied the principle of productive failure to mathematical problem solving in three schools．
With one group of students，the teacher provided strong"scaffolding"--instructional support and feedback．With the teacher's help，these pupils were able to find the answers to their set of problems．Meanwhile，a second group was directed to solve the same problems by cooperating with one another，without any hints from their instructor．These students weren't able to complete the problems correctly．But in the course of trying to do so，they generated a lot of ideas about the nature of the problems and about what potential solutions would look like．And when the two groups were tested on what they'd learned the second group"significantly outperformed"the first．
The apparent struggles of the second group have what Kapur calls a"hidden efficacy"：they lead people to understand the deep structure of problems，not simply their correct solutions．When these students meet with a new problem of the same type on a test，they're able to transfer the knowledge they've gathered more effectively than those who were the passive recipients of someone else's expertise．
In the real world，problems rarely come neatly packaged，so being able to discern their deep structure is key．But，Kapur notes，none of us like to fail，no matter how often Silicon Valley entrepreneurs praise the beneficial effects of an idea that fails or a start-up company that crashes and burns．So we need to"design for productive failure"by building it into the learning process，Kapur has identified three conditions that promote this kind of beneficial struggle．First，choose problems to work on that"challenge but do not frustrate．"Second，provide learners with opportunities to explain and elaborate on what they're doing．Third，give learners the chance to compare and contrast good and bad solutions to the problems．And to those students who protest this tough-love teaching style：you'll thank me later．

4．Dutch designer Jeffrey Heiligers'latest clothing line-"Posture"-targets people who spend most of their time hunched（弯腰驼背） over a computer．
By preventing the wearer from hunching，the clothes help people improve their posture in the long run．The concept is simple-every time you hunch，the shirt will tighten uncomfortably around the back，forcing you to sit upright again．
"I engineered a tailor-made treatment that corrects poor posture，nowadays very common among the digital generation，not by constraining（约束） the muscles，but by training them，"Heiligers told Dezeen magazine．"Posture offers a solution integrated in the clothes you wear．By repositioning the seams in such a way that they start to feel uncomfortable when hunching，it stimulates you to sit up straight．"
Heiligers revealed that a physiotherapist was involved in the designing process．They began by identifying the various sitting and standing positions that cause neck，shoulder，and back pain．Heiligers then cut the fabric across the back，in order to make the clothes tighten slightly when the wearer hunches forward．The discomfort will remind the wearer to adjust their posture，and their muscles will eventually get trained to sit and stand the right way．
The Posture range are all constructed differently to normal clothes．Heiligers pointed out that the clothes are special because the more they are used，the less they are needed．He chose to use only a few colors-white，grey，blue-because he wanted to create an everyday collection．"More and more people become hunch-backed because they use more and more electronic devices．I would like the clothing industry to be inspired by the clothes I created and to adopt it to prevent back problems in the future．I'm sure what I created will have a bright future，"Heiligers said．

29．What might be the author's purpose in writing the text？C
A．To tell a new treatment for a common disease．
B．．To seek help for people who are hunch-backed．
C．To introduce a kind of special products．
D．To give some advice on how to prevent hunching．
