This study reported the first interdisciplinary Aggie Sleuth Initiative (AggieSI) conducted between the Departments of Political Science and Criminal Justice, Sociology and Social Work and Chemistry in order to interest underrepresented minority students in the field of forensic science at North Carolina Agricultural and Technical State University (NCA&T). The AggieSI project involved a “simulated crime scene” and a “hypothetical narrative” that provided the “simulated circumstances” for the AggieSI exercise. The students worked in groups on their AggieSI projects in a guided inquiry laboratory experiment format. The students found their AggieSI project motivating, promoting the students’ critical thinking, problem-solving and teamwork skills with students from other departments. This project also promoted mutually beneficial collaborations and partnerships between NCA&T and the local Police Department to further promote forensic studies and to ensure justice and public safety in our community. 相似文献

Science literacy leading to fuller and informed participation in the public debate about science, technology, society, and
environmental (STSE) issues that produce justified decisions and sustainable actions is the shared and central goal of the
Pacific CRYSTAL Project. There is broad agreement by science education researchers that learners need to be able to construct
and interpret specific scientific discourses and texts to be literate in science. We view these capabilities as components
in the fundamental sense of science literacy and as interactive and synergetic to the derived sense of science literacy, which
refers to having general knowledge about concepts, principles, and methods of science. This article reports on preliminary
findings from Years 1, 2, and 3 of the 5-year Pacific CRYSTAL project that aims to identify, develop, and embed explicit literacy
instruction in science programs to achieve both senses of science literacy. A community-based, opportunistic, engineering
research and development approach has been utilized to identify problems and concerns and to design instructional solutions
for teaching middle school (Grades 6, 7, and 8) science. Initial data indicate (a) opportunities in programs for embedding
literacy instruction and tasks; (b) difficulties generalist teachers have with new science curricula; (c) difficulties specialist
science teachers have with literacy activities, strategies, genre, and writing-to-learn science tasks; and (d) potential literacy
activities (vocabulary, reading comprehension, visual literacy, genre, and writing tasks) for middle school science. Preinstruction
student assessments indicate a range of challenges in achieving effective learning in science and the need for extensive teacher
support to achieve the project’s goals. Postinstructional assessments indicate positive changes in students’ ability to perform
target reading and writing tasks. Qualitative data indicate teachers’ desire for external direction and the need for researchers
to expand the literacy framework to include oral discourse. A case study of teachers’ use of a specific literacy task and
its influence on students revealed indications of robustness and effectiveness. Experiences revealed procedural difficulties
and insights regarding community-based research and development approaches. 相似文献

The aim of this study was to assess the effects of variations in the volume and intensity of resistance training in highly skilled athletes on neural adaptive mechanisms: the maximality and pattern of neural drive. The maximality of muscle activation was measured using a high-resolution sample and hold amplifier to record interpolated twitches. The pattern of neural drive was measured by analysing isometric torque-time curves and electromyographic (EMG) characteristics during the performance of rapid isometric contractions at maximal effort. The volume and intensity of training were varied at 4-weekly intervals to systematically emphasize the development of strength, power and motor performance in 14 highly skilled track and field athletes (e.g. discus, hammer, javelin, shot put and weight). Knee extension strength increased significantly by 15% during steady maximal isometric contractions and by 24% during rapid isometric contractions at maximal effort after the 16-week training programme (P < 0.05). Increases in EMG amplitude and rate of EMG activation indicated that improvements to the pattern of neural drive occurred with sport-specific resistance training (P < 0.05). The maximality and pattern of neural drive did not change in the control group. 相似文献
