This study examined the effects of input-oriented and output-oriented tasks with different involvement load indices on Iranian EFL learners' comprehension and production of lexical collocations. To achieve this purpose, a sample of 180 intermediate-level EFL learners (both male and female) participated in the study. The participants were in six experimental groups. Each of the groups was random...

In an attempt to support traditional classroom assessment processes with fully computerized methods, we have developed a method for adaptive assessment suitable for well structured domains with high emphasis on problem solving and capable of robust continuous assessment, potentially encouraging student’s achievements, reflective thinking, and creativity. The method selects problems according to...

Taskflow-oriented programming merges concepts from structured programming, hardware description, and mark-up languages. A mark-up language such as XML supports a well-defined schema that can capture the decomposition of a program into a hierarchy of tasks. A hardware description language such as VHDL relies on well-defined and explicit input/output port definitions to create, at any level of hi...

A markup language such as XML supports a well-deened schema that can capture the decomposition of a program into a hierarchy of tasks.

Recursive Deep Models have been used as powerful models to learn compositional representations of text for many natural language processing tasks. However, they require structured input (i.e. senti...

abstracttask-based language teaching is considered an effective way to achieve a harmony between grammar and communication. the present study investigates two different ways of teaching modal verbs: task-based versus traditional approaches. to this purpose, an oxford placement test was administered to select 40 homogeneous participants out of a larger population who took this test. the selected...

This study investigated the effects of different output-based task repetition conditions on EFL learners’ speech act production. Three intact classes of English-major students constituted three instructional groups: (1) the explicit task-repetition (ETR) group, (2) the implicit task-repetition (ITR) group, and (3) the no-input task repetition (NTR) group. All the three groups engaged in t...

Learning mappings between arbitrary structured input and output variables is a fundamental problem in machine learning. It covers many natural learning tasks and challenges the standard model of learning a mapping from independently drawn instances to a small set of labels. Potential applications include classification with a class taxonomy, named entity recognition, and natural language parsin...
