grading system

[edit]

This property was requested after extensive consultation with the Wikidata community and experts on ed tech, OER, global and national curriculum, education policy, and digitization. Over the two rounds of the consultation, we received input from 31 individuals representing various global perspectives and areas of expertise to aid in the full implementation of the Wikidata for Education project.

Originally proposed at Wikidata:Property proposal/Generic

   Done: grading system (P11356) (Talk and documentation)
DescriptionThe value indicators used by educators to evaluate the performance of the pupils in exams on the standard particular scales which is based on the points entirely and consist of the grades like A-F or range like 1-10

Motivation

[edit]

This property will be used to specify the grading system that is used for curriculums of specific educational systems. Some educational systems use alphabets-letter grading system (A or A+ for gce) for grading while others use numbers-Numeric grading system (grade 1 for BECE) and others combine alphabets with numbers numbers-alpha-numeric grading system (eg. A1 for Wassce). Each country follows a specific grading system. This property is needed to differentiate between different grading systems. Grading System By Country.

Discussion

[edit]

I think the relationship should probably be expressed the other way around. For example: WASSCE (Q3308424) -> is a grading system for -> mathematics (Q395). Lectrician1 (talk) 13:59, 26 April 2022 (UTC)[reply]

Thank you for this feedback. However, per the guidelines for adding examples to the property requests, it states to use ITEM -> value. Hence, the reason for using this format. So the example is reading: the subject mathematics (Q395) has a grading system WASSCE (Q3308424). The reason is, a particular subject may have one or several grading systems. Per the model that I am working with found here, the grading system (WASSCE) is a property of the Item (Ghana National Curriculum for Senior High School). The inverse is also possible where WASSCE (Q3308424) is the grading system for several subjects - but not for this use case. Andrews Lartey (talk) 17:58, 26 April 2022 (UTC)[reply]
  1. What qualities makes a grading system distinct from others? Should, for example, the values for the proposed property indicate both labels used (letters vs. numbers vs. descriptions) and the range of values used in the system ("A, B, C, ..." vs. "1, 2, 3, ...", etc.)?
  2. What classes of objects does this property apply to? The three I can think of are educational institution (Q2385804), course (Q600134), and test (Q27318). Should these all be modeled the same way? In the US, most schools use a numeric GPA, most classes use letter grades (based on percentages, sometimes), and most tests use percentages or letter grades. There is some overlap between each.
  3. At a given point in time, would each item have a unique value for the proposed property? Some colleges and classes allow students to choose between pass/fail and a letter grade.
  4. Should we make a distinction between grading systems that are subjective vs. objective? For example, an English paper is graded based on the opinion of the grader but a multiple choice test is not. Math exams are somewhere in the middle.
Before this property is created, I would like to see examples of how this property would model the following grading systems:
  • Letter grades with different ranges (most US colleges use F=0 and A=4, but some US high schools use a range of 0 to 5, where A=5 for advanced placement courses).
  • Letter grades with and without plus/minus grading (i.e., are "A-", "A", and "A+" all possible or only an "A"?).
  • Percentage (as in a test that reports 68% of answers correct).
  • Percentile (as in tests that reports a student scored in the top 12%).
  • Pass/Fail
  • Other? Perhaps some schools or courses use non-letter grading such as "acceptable", "outstanding", etc.

Here are some examples of how this property could be used. I will start with the Graduate Record Examinations (Q1197756) test. For the GRE test, there is both a numeric score and a percentile given and there are three different test sections which have different number ranges. Thus, I think we should simply put multiple statements on the GRE item:
For a school, we could have the following
For classes, we could have the following
I still am not sure how to handle systems that have a grading system that is both, say, A, B, C, D, E, F grading system with plus/minus (Q113962476) and 4.0 GPA scale (Q113962345). Any ideas?

@Lectrician1:, @Dnshitobu:, @Lymantria:, @Andrews Lartey: Do you have any thoughts on my comments, above? Do the examples I give seem like a good way to use the proposed property? Are there any other examples we should consider? — The Erinaceous One 🦔 04:22, 18 September 2022 (UTC)[reply]
This seems like a good approach. Lymantria (talk) 06:49, 18 September 2022 (UTC)[reply]
@The-erinaceous-one So for the AP Physics class example, would you be documenting that AP Physics is a class availible at a school (idk if we have a "has class" property) and then 'grading system would be a qualifier of the AP Physics value? Lectrician1 (talk) 02:44, 19 September 2022 (UTC)[reply]

@The-erinaceous-one I don't think AP courses have a specific grading system. Usually that is up to the school to implement and can thus vary from school to school. Lectrician1 (talk) 12:48, 19 September 2022 (UTC)[reply]
  • @Lectrician1: Yes, you're right, that made it a poor choice of example. I expect that the proposed property will rarely be used on classes, so I think it would be better to focus on schools and stardized tests. (On a related note, I started a discussion in the WikiProject Education regarding the organization of AP classes in WikiData.)

To model schools that, say, use an 4.0 GPA scale (Q113962345) and a A, B, C, D, E, F grading system with plus/minus (Q113962476), should we simply have a separate 'grading system' statement for each? For example,
Or, should we find a way to combine these two pieces of information? Or should we only include one of them with the proposed property? — The Erinaceous One 🦔 07:51, 21 September 2022 (UTC)[reply]
@Lectrician1 & @The Erinaceous One Thank you so much for your detailed comments, with examples. The team has been meeting the advisory council for this project who have shareed their insights as well. At the moment, we are on the drawing table to better align this particular propery with all the tangents you have pointed out. We really love you for the good job and we will keep you posted on the discussion page in furtherance. Dnshitobu (talk) 22:04, 21 September 2022 (UTC)[reply]
