“…Instances of water analysis by undergraduates using ion chromatography (3) and capillary electrophoresis (4,5) have been reported in this Journal, as has the use of advanced instrumentation to influence student attitudes and understanding (6)(7)(8). The project described here expands upon the examples in the literature that illustrate improved scientific understanding (9)(10)(11) and science attitudes (12)(13)(14)(15)(16)(17)(18) resulting from collaborative learning (12)(13)(14)(15) and interdisciplinary undergraduate student research (13,19,20).…”

Improving Student Attitudes about Science by Integrating Research into the Introductory Chemistry Laboratory: Interdisciplinary Drinking Water Analysis

et al. 2010

The integration of student research into a general chemistry laboratory and an environmental geology course has been evaluated for its effectiveness to improve (i) student attitudes about science and chemistry, (ii) student understanding of the nature of experimental science and the scientific method, and (iii) student perceptions of the application of science and the interdisciplinary nature of science. Students in introductory science courses frequently devote all or most of their time and effort to learning basic laboratory techniques by following predefined procedures that have intentionally predictable outcomes. Though this longstanding model of laboratory structure is an important means of effectively preparing students for future chemical study, it often neglects items i−iii. Students were guided through a research experience by an interdisciplinary team of faculty so that students could begin the research and bring it to an appropriate conclusion, including formal presentations, within a single semester. Evaluation of this instructional strategy indicated that students believed they were doing work similar to a research scientist, that they appreciated this opportunity to do research, that it increased how much they like science in general, and that they were more likely to consider majoring in chemistry. The advanced instrumentation, personal relevance of the research, and collaborations (within and outside the department) contributed significantly to the overall success of the project.

“…GTAs demonstrated techniques and provided relevant, helpful advice on the work progress during the lab session. The interactions of PChK-1 correspond most closely to the UG's procedural emphases in that UGs wish to get the lab experiment started quickly and finished quickly (Malina and Nakhleh, 2003). Much of the knowledge employed in PChK-1 may have been generated from the GTA's own UG lab experiences because the teaching model in those labs was more likely to have been one primarily of transmitting procedural knowledge (Abraham et al, 1997, Hilosky et al, 1998.…”

“…La mayoría de las interfaces de adquisición de datos son multipropósito lo cual hace de los instrumentos virtuales instrumentos muy versátiles. Existen muchos ejemplos de instrumentación virtual avanzada aplicada a laboratorios de investigación [14], [15], [16], [17] y en todos ellos el computador juega un papel fundamental como herramienta de análisis y almacenamiento de datos. Las variables más comunes en este tipo experimentos son temperatura, nivel, presión, voltaje y resistencia.…”
