collective learning

共同学习

Collaborative learning is a situation in which two or more people learn or attempt to learn something together. Unlike individual learning, people engaged in collaborative learning capitalize on one another's resources and skills (asking one another for information, evaluating one another's ideas, monitoring one another's work, etc.). More specifically, collaborative learning is based on the model that knowledge can be created within a population where members actively interact by sharing experiences and take on asymmetry roles. Put differently, collaborative learning refers to methodologies and environments in which learners engage in a common task where each individual depends on and is accountable to each other. These include both face-to-face conversations and computer discussions (online forums, chat rooms, etc.). Methods for examining collaborative learning processes include conversation analysis and statistical discourse analysis.

Ecuador

厄瓜多尔，南美国家

The majority of Ecuadorians trace their origins to one or more of three geographical sources of human migrations: the pre-Hispanic indigenous populations who settled the region over 15,000 years ago, the Europeans (principally Spaniards) who arrived over five centuries ago, and ultimately the black sub-Saharan Africans whom they imported as slave labor during the same period. The mixing of two or more of these three groups established other mixed ethnic groups.

whole number

整数，whole numbers 是包含了 0 的 natural numbers

In mathematics, the natural numbers are those used for counting (as in "there are six coins on the table") and ordering (as in "this is the third largest city in the country"). In common language, words used for counting are "cardinal numbers" and words used for ordering are "ordinal numbers".

Some definitions, including the standard ISO 80000-2, begin the natural numbers with 0, corresponding to the non-negative integers 0, 1, 2, 3, …, whereas others start with 1, corresponding to the positive integers 1, 2, 3, …. Texts that exclude zero from the natural numbers sometimes refer to the natural numbers together with zero as the whole numbers, but in other writings, that term is used instead for the integers (including negative integers)

Dominoes is a family of games played with rectangular "domino" tiles. Each domino is a rectangular tile with a line dividing its face into two square ends. Each end is marked with a number of spots (also called pips, nips, or dobs) or is blank. The backs of the dominoes in a set are indistinguishable, either blank or having some common design. The domino gaming pieces (colloquially nicknamed bones, cards, tiles, tickets, stones, chips, or spinners) make up a domino set, sometimes called a deck or pack. The traditional Sino-European domino set consists of 28 dominoes, featuring all combinations of spot counts between zero and six. A domino set is a generic gaming device, similar to playing cards or dice, in that a variety of games can be played with a set.
