In two experiments, participants made inferences from weather maps, before and after they received instruction about relevant meteorological principles. Different versions of the maps showed either task-relevant information alone, or both task-relevant and task-irrelevant information. Participants improved on the inference task after instruction,…

The determination of bounds for A(n, d, w), the maximum possible number of binary vectors of length n, weight w, and pairwise Hamming distance no less than d, is a classic problem in coding theory. Such sets of vectors have many applications. A description is given of how the problem can be used in a first-year undergraduate computational…

Variable reinforcement schedules are used to arrange the availability of reinforcement following varying response ratios or intervals of time. Random reinforcement schedules are subtypes of variable reinforcement schedules that can be used to arrange the availability of reinforcement at a constant probability across number of responses or time.…

Teams of educators conducted lesson study independently, supported by a resource kit that included mathematical tasks, curriculum materials, lesson videos and plans, and research articles, as well as protocols to support lesson study. The mathematical resources focused on linear measurement interpretation of fractions. This report examines the…

This ethnographic study of language shows the importance of educators' appropriate use of linguistic, nonlinguistic, and paralinguistic communication techniques when working with elementary students within two classrooms who have behavioral and emotional disorders. This study focused on communication techniques used by teachers and…

The Draw an Engineer Test (DAET) is a common measure of students' perceptions of engineers. The coding systems currently used for K-12 research are general rubrics or checklists to capture the images presented in the drawing, which leave out some of the richness of students' perceptions, currently only captured with an accompanying student…

The use of problem-solving strategies by 59 deaf and hard of hearing children, grades K-3, was investigated. The children were asked to solve 9 arithmetic story problems presented to them in American Sign Language. The researchers found that while the children used the same general types of strategies that are used by hearing children (i.e.,…

The purpose of this qualitative study was to analyze the self initiated conversations held by school principals on web2.o platforms, such as blogs, through the lens of current leadership standards. The online writings of thirteen school principals were analyzed using grounded theory techniques (Strauss and Corbin, 1998) to elucidate emerging…

This exploratory study assessed the associations of age, gender, and a school climate of solidarity and pride with adolescents' endorsements of democratic regime change. Middle- and high-school students (N = 273) in the United States responded to three vignettes concerning how a society should transition from dictatorship to democracy and…

This article aims at validating a coding scheme designed to investigate the precursors of academic language occurring in early caretaker-child interactions. Exposure to the academic dimensions of language is an important asset for children to be successful in academic settings. The proposed analytical framework, based on systemic functional…

In most post-secondary Spanish language programs in the U.S., heritage language (HL) learners and second-language (L2) learners are enrolled together, in the same courses (Ingold, Rivers, Tesser, & Ashby, 2002). Nevertheless, there is scant empirical research on what actually goes on in these classrooms and what the nature of learner-learner…

In the literature, there has been a focus on the effectiveness of larger sized electronic brainstorming groups; however, mechanisms for its effectiveness still remain open to question and some methodological concerns (e.g., the evaluation of ideas and the typing speed, and the use of different formats) continue to be important problems. To…

Infants from birth itself are in constant interaction with their mothers and the environment. Thus the maternal styles of communication would play an important role in developing communicative competency in children. This process happens so naturally and incidentally that no one pays special attention to it. However, when a hearing impairment is…

National standards for learning foreign languages describe five area goals which are intertwined and interconnected in the K-12 learning environment; yet, absent from the literature are investigations on how K-12 teachers are able to implement and incorporate the "practices, products, and perspectives" of culture into world language…

This research explored how a group of religious leaders and scholars understand and make meaning of their experience in interfaith dialogue, and the reported impact it had on their spiritual and professional practice. It considered a broad range of themes, including participants' motivation to engage across religious difference, their…
