6 . Educational technology such as apps can help students with time management, organization skills, study skills, homework and more. Below is a list of apps for college students recommended by educational technology experts. The needs of individual students differ and experts suggest that students try out several apps to find the right one. Unless costs are noted in the apps’ descriptions below, these learning tools are free to users:

Blackboard App. A popular learning management system, Blackboard is used at many colleges across the U. S. It allows students to get course work for online classes or in-person classes. Students can view course content, complete assignments and tests, view graded and more.

Duolingo. Advertising itself as “the world’s best way to learn a language”, Duolingo offers lessons in 35- plus languages, helping users with speaking, reading, listening, writing, grammar and vocabulary. Duolingo offers both free and paid versions, the latter with an ad-free experience and of line access to lessons.

Evernote. A note-taking and task-management system that offers the ability to sync across devices. Evernote allows users to create to-do lists, save web pages and change documents into a digital form via a device’s camera.

Ever note is free, though an advanced version with more feature costs $7.99 a month or $69.99 a year.

College mobile apps. College-specific apps have become fairly common among U. S. college students. While these apps may differ by college, users can often find campus maps, news, safety information, scheduled events and more.

Chair Transformation Number 20B, made in 1996 — by Lucas Samaras

Here, Samaras explores the double meaning of “flight”, referring to both the starlike form created by the stacked chairs, and the movement of a single chair moving through space. From different viewpoints, the sculpture appears to be upright, leaning back, or springing forward. From the side, it even appears like a zigzagging (之字形的) line.

Typewriter Eraser, Scale X, made in 1998 — by Coosje van Bruggen

The artist chose the typewriter eraser as his model for this work based upon childhood memories of playing with the object in his father’s office. Here the brush arcs (作弧形运动) back, conveying a sense of motion, as if the wheel­like eraser were rolling down the hill and making its way towards the gate of the garden.

Moondog, model 1974, made in 19981999 — by Tony Smith

The title itself comes from two sources: Moondog was the name of a blind poet and folk musician who lived in New York City, and Smith has also compared this sculpture to Dog Barking at the Moon, a painting by Joan Miro. He first created Moondog in 1974 as a 33­inch cardboard model and cast it in bronze as a garden sculpture in 1980. This version was designed by Smith, but it was not completed until after his death.

Cheval Rouge (Red Horse), made in 1964 — by Alexander Calder

During the last two decades of his life, Alexander Calder devoted his greatest efforts to large­scale mobiles and stabiles (立式抽象派雕塑), many of which have become popular public landmarks in cities around the world. Here the silky legs and tensile (张力的) up­thrust “neck” recall the power of a horse. This stabile reflects Calder's statement: “I want to make things that are fun to look at.”
