Match Technology is helping teachers to expand beyond traditional, text-based learning and to engage students who learn best in other ways. Its role in schools has developed from a ‘computer class’ into a versatile learning tool that could change how teachers demonstrate concepts, assign projects and assess students’ progress. A It can be hard to show students some concepts such as exactly why mixing two particular chemicals is dangerous. ^Digital simulations can help teachers explain concepts that are too big or too small, or processes that happen too quickly or too slowly to demonstrate in a classroom. Simulations allow students to experiment with virtual greenhouses in order to understand how plants develop. Other software helps students understand the physics of energy efficiency by designing a model house. These are all concepts that are much harder to understand by simply reading. B Education, by its very nature, produces huge amounts of data and teachers can use this data to better understand what a student knows and what he or she still needs to learn. Furthermore, these measurements make it possible to provide every student with a constantly updating, personalised textbook, with exactly the exercises and information he or she needs to study in order to understand the course material and get ahead. A teacher can see exactly how well her students understood that tough biology lesson at the beginning of the week. She can see that Jane needs extra help understanding cell biology, and can look at what percentage of her students are prepared for next month’s exam. C Technology also helps to make the world a smaller place. Language students can use video conferencing to attend lessons with native speakers living in other countries. In the past, only students who could afford to travel had the experience of learning a foreign language and about another culture. Now the educational benefits of interaction with a native speaker are available to anyone who can make a video conferencing call. D Games are another great way technology has improved the learning experience. There are games that put students in roles like hotel manager, teacher or scientist and ask them to solve real problems. In one game, students are directors of a video game company who need to develop and market a new game. In another, the game gives students the task of designing a new transport system for London. People working in different industries can learn innovative thinking through these games. Unlike in traditional classrooms, they develop practical skills by working together to solve real-world problems. 1 how technology helps teachers check understanding Answer 2 how technology can improve international communication and understanding Answer 3 how games can help learning Answer 4 how technology can show difficult ideas to students Answer 5 how non-traditional teaching methods are suitable for creative people Answer 6 how designing something themselves helps students understand scientific facts

Match A. If none of the options listed above suits your needs, you have another alternative that doesn’t require planting of other plants or crops on your land and allows you to create a clean look to your property. You can protect the soil by covering exposed spots around the plants with a mulching material. By putting down mulch, you are keeping bare soil from being washed and eroded away, as well as helping to retain soil moisture and eliminate weed growth around your carefully selected plants. Mulching layer stabilizes soil temperature, protecting plants and soil from the effects of fluctuating temperature in winter. B. You can create neatly looking dry creeks that direct water away from your land or channel runoff to your designated area from where you can reuse it (e.g. for irrigation). Dry creeks look like a small version of a rocky river bed and even imitate its function. You also have an option to plant vegetated filter strips or simply install drainage pipes to gather water and carry it away from critical areas. Some people choose to protect land around their houses by implementing so called French drains. French drains are trenches along outer house walls that contain drainage pipes covered by permeable gravel. C. Growing crops on slopes can be particularly challenging and plowing on slopes can easily lead to soil erosion. However, there are several techniques for cultivating crops on slopes that prevent erosion. These include contour farming, where farmers plow and plant across a slope along its contour lines as opposed to planting in downhill facing lines. D. When talking about soil erosion control measures, we should not neglect the areas that have already been damaged but have a potential for great improvement when managed properly. Restoration of degraded ecosystems and protection of marginal areas to ensure that we will place sufficient soil erosion prevention methods in place is crucial. E. Land that is used for livestock grazing is often hilly or is located in marginal areas that are unsuitable for crop cultivation. Unsustainable livestock management on such lands leads to overgrazing and decreases the protective groundcover. When more than 60 percent of vegetation gets removed, the rate of erosion accelerates, and topsoil is more likely to be washed off with every rainfall event. F. Whether on a large scale, like rice fields, or on a smaller scale in your backyard, terracing allows cultivation and erosion control of many difficult slopes that would otherwise be unsuitable for any activity. With the structural support of retaining walls, terraces can create a nice decorative element on your property, giving it a new look. They can be useful for the creation of raised garden beds that are for many gardeners more comfortable to maintain. G. It is recommended to plant cover crops after the harvest of the main crop. Take for example corn. Once you harvest corn, the land will most likely remain barren over the winter. This means that the soil will lack the protective layer of growing vegetation in the season when it rains or snows a lot and the land is subjected to cycles of freezing and unfreezing. This easily damages soil structure and increases the risk of soil loss. 1) A number of techniques allow farmers to overcome issues with slanted landscapes in farming. Answer 2) Without an abundance of plants, the wind and rain will wear away the land more quickly. Answer 3) When the land is emptier, it is more prone to damage and lose earth. Answer 4) Adding a cover protects the land and keeps soil from being harmed by fluctuating temperatures. Answer 5) Another way to protect soil is to redirect water away from where plants are being grown. Answer 6) By becoming frozen and then thawing out, farmers may experience harm to soil or a reduction in the amount of soil. Nhanh ạ
