"For the purposes of the current research, strength of grammatical knowledge is defined as the extent to which a test-taker can answer correctly a variety of items requiring different types of cognitive processing, all measuring the knowledge of the same grammatical structure.
As a result, grammatical assessment studies that have imitated the specifications of grammar section of pre-2005 TOEFL with only MC type item formats may have risked construct underrepresentation, in case they have made claims relating to a test-taker's profile of weaknesses and strengths with regard to knowledge of grammar.
Investigating the consistency of relationship To examine the relationship among complexity, range, and strength and how the relationship among these dimensions changes as learner’s grammatical knowledge develops, two sets of analyses were conducted after dividing the participants into a higher (HG) and a lower group (LG).
To find the extent to which complexity, range, and strength dimensions of grammatical knowledge can explain the greatest amount of variance in EFL students’ knowledge of grammar, stepwise multiple linear regression analysis, as one of the strongest statistical analyses used for predictive purposes (Brace, Kemp & Sneglar, 2000), was conducted separately for each group to investigate whether the model of GK in two groups is different.
Further research is suggested to employ the framework for grammatical knowledge proposed in this study as it can offer a means of measuring the increase in complexity, range, and strength of second language grammar as learners’ language proficiency develops."
