Introducing effective approaches and providing equal opportunities for all language learners at any level of language knowledge to learn successfully seems to be an asset. In this study, the role of employing Partnership Approach (PA) to teach speaking to undergraduate EFL students through Streaming/Homogeneous-Grouping of the learners in Mixed-Ability classrooms was examined. A quasi-experimen...

OBJECTIVES Much of adaptive behavior relies on the ability to learn and generate predictions about relationships in the environment. Research on aging suggests both that there is an age deficit in the ability to learn sequential relationships and that this deficit in learning could underlie age differences reported in many decision-making tasks. This article introduces the Triplets Prediction T...

The success of machine learning in a broad range of applications has led to an ever-growing demand for machine learning systems that can be used off the shelf by non-experts. To be effective in practice, such systems need to automatically choose a good algorithm and feature preprocessing steps for a new dataset at hand, and also set their respective hyperparameters. Recent work has started to t...

Social media have enjoyed a rapidly increasing adoption among users in recent years. Millions of users execute billions of actions (in form of tweets, messages, replies, likes, etc.) every day. The massive amount of social interactions online has contributed to the proliferation of social advertising. Alongside the interest in online and social advertising, Twitter has introduced several advert...

l present a cognitive model of the human ability to acquire causal relationships. I report on experimental evidence demonstrating that human learners acquire accurate causal relationships more rapidly when training examples ore consistent with a general theory of causality. This article describes o learning process thot uses a general theory of causality as background knowledge. The learning pr...

was to determine if the aptitude of girls entering a class in garment machine operating could be measured.2 In outlining the experiment, it was felt that if significant relationships were found the test could be used in place of an actual try-out on the machines to weed out probable successes from probable failures among further applicants for such trade training. When significant relationships...
