问题 单项选择题

信息系统设计方案中的操作界面部分,特别是输入界面设计方案需要征求信息处理技术员的意见。在如下设计理念中,______是不正确的。

A.用户在输入框中输入信息并按Enter键后,光标应自动移到下一输入框

B.性别、学历等信息的输入可采用单选按钮或下拉列表框形式

C.为了美观起见,输入框中的信息应要求用户用宋体居中输入

D.对用户输入的信息应尽量立即自动进行有效性校验,并提示错误

答案

参考答案:C

解析:信息系统的操作界面是系统操作员常用的界面,设计时除了要体现系统功能的完整性外,还应符合人们的操作习惯。特别是输入界面,那是信息处理技术员需要大量操作的界面。偶尔操作的人员对界面的方便性要求不高,但对于大量操作的人来说,不方便的操作界面是很麻烦的,甚至是痛苦的,也会导致输入错误增多。
输入界面中一般会有多个输入框。由用户移动光标,再逐框输入是很麻烦的,也容易出错。系统应尽量帮助用户实现光标自动定位。
对于性别的输入,采用单选按钮很方便,甚至采用默认值后,会有一半多的情况无需输入。对于学历输入,采用下拉列表框(也可以用单选按钮)是方便的,减少了输入操作量,加快了操作速度,减少了出错的可能。
要求用户输入信息后,再进行居中对齐,并改用宋体显示,这是没有必要的。一般按默认的左对齐方式、默认的字体输入就可以了。即使为了美观,也不应该让用户输入时排版,而应由程序自动设置好。
对有些输入信息可以用编程办法进行有效性校验,例如事先规定数值的范围、输入字符的限制、与其他字段信息的匹配等,发现错误后立即提示错误,这样可以减少系统输入的出错机会,对操作员和信息系统的成功运行都十分有利。

China is now sending more college students to study in the United States than any other country.  A new report shows a 23 percent increase in the number of Chinese students coming to the U.S.

The latest edition of the annual Institute of International Education(IIE)and another US institute found a 5 percent rise in the number of international university students in the US compared to one year ago. There are now over 157, 000 Chinese students at U.S. colleges and universities.

Aisa accounted for four of the top five countries and regions to take advantage of the US higher education system. “Increased numbers of students from China, particularly at the undergraduate level, largely accounts for the growth this past year,” the report stated. “They really enroll in a full range of US higher education,” said Peggy Blumenthal, senior counselor to the president of IIE, the group that made the report. “20 years ago, students from China only knew of a handful of US insitiutions, but now, they are enrolling in our community colleges, in our small liberal arts institutions, in the research universities. Really spread across the country,” she said.

Chinese mainland was in the number one spot, while India was the number two country of origin. South Korea was third and Canada was number four. China’s Taiwan held the number five spot. Saudi Arabia was in sixth with a 44-percent increase, while Japan was seventh, down 14 percent.

Blumenthal attributes the increase in the number of Chinese students heading to US colleges to limited university places in China, as well as a feeling from students and their parents than they want a “unique” educational experience. China’s family planning policy, says Blumenthal, has also meant that families can concentrated resources on a single child.

The University of California at Los Angeles has one of the largest Asian student populations of any college in the United States.
