In order to investigate the influence of separation of grade distributions and ratio of common items on the precision of vertical scaling, this simulation study chooses common item design and first grade as base grade. There are four grades with 1,000 students each to take part in a test which has 100 items. Monte Carlo simulation method is used…

In French-speaking Belgium, one of the new tasks of the teacher will be to develop the informational skills of learners.

Two experiments aim at describing the impact of friendship during a synchronous collaborative information retrieval (SCIR) with young pupils (recruited in Grade 3). In the first study, 68 pupils were asked to look for 13 answers in one of the three following conditions: on an individual basis (condition "Single"), as part of a designed duo with…

Acrostic poems make use of a keyword written vertically, where each line of the poem begins with a letter of the keyword.

In an inquiry-based classroom, student interest is at the heart of curriculum planning, instruction, and assessment. Students are responsible for asking questions, using sources effectively to discover answers, and deciding what format would best present their findings. Aside from creating a sense of ownership, inquiry in the classroom engages…

This research aims at promoting the usage of an online children's dictionary within a context of reading comprehension and vocabulary acquisition. Inspired by document retrieval approaches developed in the area of information retrieval (IR) research, we adapt a particular IR strategy, based on fuzzy logic, to a search in the electronic dictionary.…

This study tested the hypothesis that children with high working memory capacities solve single-digit additions by direct retrieval of the answers from long-term memory more often than do children with low working memory capacities. Counting and reading letter span tasks were administered to groups of third-grade (mean age=107 months) and…
