Previously, a small scale, interview-based, 3-year longitudinal study (ages 11-14) in one school had suggested a learning progression related to the concept of a substance. This article presents the results of a large-scale, cross-sectional study which used Rasch modeling to test the hypothesis of the learning progression. Data were collected from…

The aim of this paper is to explore the influence of peer behaviour on student marijuana consumption. Our hypothesis is that, in contrast to the traditional measures of peer group effects carried out at class or school level, the use of a closer peer group, which we relate to the group of friends, is more relevant in the explanation of marijuana…

In response to a direct request from science teachers, researchers initiated a pilot experience on animal orientation and navigation, which was delivered to 61 13-year-old students in Florence, Italy. The aim was to explain the approach to ethology and to link animal navigation with geography, focusing on species crossing the Italian territory.…

The present study illuminates and diagnoses the learning problems of the rural learners in English Grammar at standard VI. Present study may be useful to ameliorate the rural learners for acquiring competencies in English and eliminates the problems of the learners. It paves way to the teachers to diagnose the learning hurdles of the learners and…

This study investigates the effect of Emotional Intelligence (EQ) training on student satisfaction with the collaborative writing process and product. Business communication students at an AACSB-accredited state university worked collaboratively on writing assignments in pre-and post-EQ-training sessions. Pre-and post-training surveys measured…

Isomorphs of a puzzle called m+m resulted in faster solution times and an easily reproduced solution path in a labeled version of the problem compared to a more difficult binary version. We conjecture that performance is related to a type of heuristic called direction that not only constrains search space in the labeled version, but also…

Since 1941, academic dishonesty has been recognized in the professional literature as a serious problem. Personality Types A and B have been suspected as contributors to cheating. In this quasi-experimental study, undergraduate and graduate students (N = 112) at one academic institution were surveyed about their attitudes and cheating behavior.…

This study investigates the hypothesis that African American students succeed in difficult circumstances due to a type of coping that is unique to the African American experience. It was tested with a survey of 147 eleventh and twelfth grade students from different ethnic backgrounds who were enrolled in a New York City high school, The survey…

Test anxiety creates problems for many students, and can have a negative impact on the academic performance of many who suffer from it (Jones & Petruzzi, 1995). Typical treatment components for test anxiety involve psychoeducation, relaxation training, gradual exposure, cognitive restructuring, study skills training, and relapse prevention.…

This study describes the realization of onset and coda clusters in a 4-year old child acquiring American English, and with a higher than usual level of unintelligible speech. It reviews previous studies that have tested cluster realization against markedness and, in particular, the sonority hypothesis. This latter predicts steep rises in sonority…

Using growth curve modeling techniques, this research investigates whether military spending improved or worsened the economic well-being of citizens within the American states during the post-Vietnam War period. We empirically test the military Keynesianism claim that military spending improves the economic conditions of citizens through its use…

The present study investigates the impact of role modeling as perceived by proteges on their personal learning (i.e., relational job learning and personal skill development) and work-to-family enrichment (WFE). Results from a two-wave field survey of 173 proteges in the People's Republic of China indicate that role modeling positively affects…

Purpose: This study tested the hypothesis that volunteering in environmental organizations in midlife is associated with greater physical activity and improved mental and physical health over a 20-year period. Design and Methods: The study used data from two waves (1974 and 1994) of the Alameda County Study, a longitudinal study of health and…

We test the hypothesis that academic entrepreneurship, resisted in the past by some as being in conflict with the long-standing Mertonian norms of open science and free enquiry, has now become widely accepted within the academy, or "taken for granted", as an institutional shift. Using responses to a series of attitudinal questions about academic…

Modern cognitive neuroscientific theories and empirical evidence suggest that brain structures involved in movement may be related to action-related semantic knowledge. To test this hypothesis, we examined the naming of environmental sounds in patients with corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP), two…
