How correctness, argumentation, and Lectical Level work together diagnostically
In a fully developed Lectical Assessment, we include separate measures of aspects of arguments such as mechanics (spelling, punctuation, and capitalization), coherence (logic and relevance), and persuasiveness (use of evidence, argument, & psychology to persuade). (We do not evaluate correctness, primarily because most existing assessments already concern themselves primarily with correctness.) When educators use Lectical Assessments, they use information about Lectical Level, mechanics, coherence, persuasiveness, and sometimes correctness to diagnose students' learning needs. Here are some examples:
This student has relatively high Lectical, mechanics, and correctness scores, but their performance is low in coherence and the persuasiveness of their answers is average. Because lower coherence and persuasiveness scores suggest that a student has not yet fully integrated their new knowledge, this student is likely to benefit most from participating in activities that require them to apply their existing knowledge in relevant contexts (using VCoL).
This student's scores, with the exception of their correctness score, are high relative to expectations. This students' knowledge appears to be well integrated, but the combination of average persuasiveness and low correctness suggests that there are gaps in their content knowledge relative to targeted content. Here, we would suggest filling in the missing content knowledge in a way that integrates it into this students' well-developed knowledge network.
The scores received by this student are high for correctness, while they are average for mechanics, and low for Lectical Level, coherence, and persuasiveness. This pattern suggests that the student is memorizing content without integrating it effectively into his or her knowledge network and has been doing this for some time. This student is most likely to benefit from applying their existing content knowledge in personally relevant contexts (using VCoL) until their coherence, persuasiveness, and Lectical scores catch up with their correctness scores.
