Students' understanding of models in science has been subject to a number of investigations. The instruments the researchers used are suitable for educational research but, due to their complexity, cannot be employed directly by teachers. This article presents forced choice (FC) tasks, which, assembled as a diagnostic instrument, are supposed to…

This paper outlines a framework to explain the early development of place-value understanding based on an analysis of data from 84 five- to seven-year-old children from diverse cultural and linguistic backgrounds. The children were assessed individually on number knowledge tasks (recalled facts, subitizing, counting, place-value understanding) and…

This study extends the evidence for implicit second language (L2) learning, which comes largely from (semi-)artificial language research, to German. Upper-intermediate L2 German learners were flooded with spoken exemplars of a difficult morphological structure, namely strong, vowel-changing verbs. Toward the end of exposure, the mandatory vowel…

Do early childhood education children comprehend photographs as spatial representations and are they able to use them to obtain information about space? Can they identify the location where the shooting was done? Can they use photographs to identify the positions where objects are located? These are the research questions that this article aims to…

The authors examined the characterization of mathematical knowledge of teachers using educative curriculum materials. In particular, they investigated knowledge of change and rate of change (in the context of algebra and functions) of 12 teachers with differing levels of experience. Participants used a same set of curriculum materials that embed…

This paper describes tasks based on real-life scenarios, which triggered reflective thinking, verbalization, and writing, leading to the creation of natural dialogues rather than artificial, dull monologues. One of the main aims of this approach is to engage students in a dynamic process of both learning about multicultural participants and…

Over the past 20 years task-based language teaching (TBLT) has become a dominant approach to teaching in many contexts, including schools in New Zealand and the Flemish speaking region of Belgium (East, 2012; Van den Branden, 2006), but there are challenges for teachers in adapting their teaching to this approach. This paper reports on a study…

Fifteen elementary and secondary teacher candidates solved sixteen integer addition and subtraction problems during think-aloud interviews. Investigators further probed participants' solution strategies as well as what they noticed first when starting a new problem. Task analyses of participants' solutions led to the creation of two distinct maps…

School impact media studies indicate that a well-staffed and funded school library media program with a certified school library media specialist (SLMS) positively correlates with increased student achievement. SLMS must have a shared understanding of their roles and responsibilities to positively impact student success. In an effort to determine…

Describes knowledge mapping, a tool developed to increase the objectivity and accuracy of task difficulty ratings for job design. Application in a semiconductor manufacturing environment is discussed, including identifying prerequisite knowledge for a given task; establishing training development priorities; defining knowledge levels; identifying…
