Organic and inorganic evidence essay
The historical evolution of the curriculum has led to multiple groupings of courses, different times offered within the curriculum, and different places in the curriculum where cross-disciplinary topics such as organometallics are taught e. The data collected in the survey do not afford us the opportunity to fully answer either set of questions; reasons for why topics were or were not covered were not collected.

Readers are encouraged to draw their own conclusions based on the data in Table 2. With the characterization of several in-depth inorganic chemistry courses, coupled with a preceding paper on characterizing the content of foundation inorganic chemistry courses, it is logical to want to consider the pairings of courses when an institution offers multiple courses. A key limitation of our survey is that participants were only asked to characterize a course as foundation or in-depth if they had taught the course in the three years prior to completing the survey.
Of the respondents, reported that their institution taught a foundation course; only actually taught that course in the prior three years. Of the respondents, reported that their institution taught an in-depth course; only actually taught that course in the prior three years. There is no evidence in the data to support a particular sequence of inorganic chemistry courses in the curriculum. None of the in-depth courses are preceded by a particular foundation course, and none of the foundation courses are followed by a particular in-depth course.
The role of the in-depth course is sometimes to drive home the fundamentals of inorganic chemistry. Other in-depth courses seek to accomplish something completely different, for example, to present a special topic in its entirety. This variation, too, is a reflection of the way in which the inorganic chemistry curriculum has evolved from a bottom-up rather than top-down approach.
Different educators approach it at their own level and in the context of their own institution. We believe this diversity is positive for the field, but it makes it challenging to draw conclusions. These results do not offer a prescription for an in-depth course in inorganic chemistry. There is no one single course in inorganic chemistry, and there is no single undergraduate inorganic chemistry curriculum.
The authors believe that the variation in the number of courses and types of courses is a strength of the inorganic chemistry curriculum. How and why the curricular variants arose have been discussed in the chemical education literature, 1, 2, 4, 12, 13, 22 but one also must consider the opportunities and limitations of institutional size e. In comparison to a more prescribed curriculum for introductory chemistry courses, the inorganic chemistry curriculum is flexible and provides many opportunities to incorporate recent developments in the field and serve the needs of individual programs.
The diversity at the in-depth course level muddles the ability for undergraduate and graduate chemistry degree programs to comparatively evaluate student learning in inorganic chemistry beyond an individual institution. When standards are considered, one must take into account the variability of inorganic chemistry curricula, including how to evaluate student learning when students may have learned different content at different points in the curricula and with differing levels of difficulty. We would like to echo the calls of the community in and again in to make sure that when the CPT guidelines are implemented, 13, 22 inorganic chemistry merits the same emphasis given to other disciplines.
In practice, this means that two or more inorganic chemistry courses or purposeful structuring of in-depth courses across the chemistry curriculum may be necessary to cover the abundance of chemistry under the purview of inorganic chemistry. A national survey of inorganic chemists was conducted in which data on topics covered in in-depth inorganic chemistry courses were gathered. Respondents in each course grouping reported variations as to how each topic area is increasing, decreasing, or staying the same in coverage with consistency of movement across several topics.
Movement in coverage mirrors the changes in emphasis on topic areas in research endeavors in inorganic chemistry e. The results of this work suggest that degree programs at the undergraduate and graduate level as well as future employers should be aware of the varying inorganic chemistry educational experiences of their students and employees.

It is unlikely, however, that such discrete categories of learning exist. Rote and meaningful learning, rather, are endpoints along a continuum of learning.

These chemicals have been proven to be harmful to the human body, unlike organic foods which are healthier, and grown at a natural and normal pace, in the soil with no added pesticides. An example to the health risks involved is cancer.
