2.1. Metacognitive Knowledge
In coining the term metacognition, Flavell (1976) [
39] defined it as “…the active monitoring and consequent regulation and orchestration of these processes [information processing activities] in relation to the cognitive objects or data on which they bear, usually in service of some concrete goal or objective.” (p. 232). Hacker (1998) [
40] further defined metacognition as the ability to be consciously aware of, monitor, and regulate learning processes [or cognition].
In Flavell’s (1979) [
2] model of metacognition, metacognitive knowledge encompasses a person’s understanding of the factors influencing their cognitive processes. It includes beliefs about the strategies necessary to achieve cognitive goals, such as comprehending reading content or solving problems. These strategies, known as metacognitive strategies, arise from learners’ awareness and concerns when tackling tasks [
41]. In reading, metacognitive strategies may involve identifying context clues, monitoring comprehension, rereading for clarity, adjusting the reading pace, and considering connections to prior knowledge.
According to Brown (1987) [
42], learners’ knowledge of their own cognition consists of several components that influence the implementation of metacognitive strategies. Declarative, procedural, and conditional knowledge are the primary components contributing to the effectiveness of metacognitive strategy use. Declarative knowledge involves factual information, procedural knowledge pertains to understanding how to perform tasks, and conditional knowledge encompasses knowing when and why to apply declarative and procedural knowledge. These components strengthen metacognitive knowledge and enable learners to employ strategies appropriately, particularly in challenging situations such as comprehending difficult texts [
43].
Flavell’s concept of metacognition has extended its influence beyond psychology into diverse academic disciplines. In the context of reading, Grabe (2009) [
44] defines metacognitive knowledge as “the knowledge and control that we have over our cognitive processes” (p. 222). Additionally, Schreiber (2005) [
45] characterizes metacognitive knowledge as involving the awareness, monitoring, and regulation of strategies. In essence, metacognitive knowledge in L2 reading entails the deliberate use of strategies to monitor and regulate reading comprehension, thus enhancing the readers’ level of engagement with the texts [

46].
2.2. Metacognitive Knowledge and L2 Reading
The importance of metacognitive knowledge in L2 reading comprehension has been well established [
4,
9,
10,
11,
12,
13]. However, the debate surrounding whether metacognitive knowledge can enhance students’ L2 reading test performance has persisted for decades.
In a recent study conducted by Zhang (2018) [
20], structural equation modeling (SEM) was utilized to investigate the impact of reading strategies on students’ L2 reading performance. The findings indicated that the use of metacognitive strategies could effectively improve students’ L2 test scores. Similarly, Seedanont and Pookcharoen (2019) [
19], Mohseni et al. (2020) [
17], and Khellab et al. (2022) [
16] investigated the instruction of metacognitive strategies in English as a foreign language (EFL) classes and reported similar findings. Seedanont and Pookcharoen (2019) [
19] and Khellab et al. (2022) [
16] examined students’ English reading test scores before and after weeks of instruction on metacognitive strategy use, while Mohseni et al. (2020) [
17] compared the reading performance of three groups: one receiving training on metacognitive strategy use, another receiving training on reading awareness, and a control group. All three studies concluded that instruction in metacognitive strategies significantly increased students’ reading test scores. Furthermore, Mohseni et al. (2020) [
17] discovered that training in reading awareness could also yield similar benefits in improving students’ test performance.
While some studies suggest that metacognitive knowledge can enhance students’ L2 reading scores, others present contrasting views, suggesting that the use of metacognitive strategies may have no direct impact, or at least a negligible one, on L2 reading test scores. A study by Shang (2018) [
29] examining the utilization of metacognitive strategies by EFL students during the reading of academic texts found that students did indeed employ a variety of metacognitive strategies to enhance their reading comprehension. However, despite the frequent use of these strategies, the results of reading comprehension tests did not necessarily reflect their benefits. Shang observed that while several of the 27 metacognitive strategies studied might have individually contributed positively to test performance, collectively, they did not significantly impact test outcomes.
Likewise, Ghaith and El-Sanyoura (2019) [
23] and Arabmofrad et al. (2021) [
22] found that the effects of metacognitive strategies on L2 reading test performance were minimal. Employing correlation analysis, both studies revealed that overall, metacognitive strategies did not significantly correlate positively with test performance. However, Ghaith and El-Sanyoura (2019) [
23] observed a slight positive correlation with strategies related to identifying answers to questions. Despite this correlation, the coefficients remained relatively low, at 0.30 and below.
In a similar vein, Yan and Kim (2023) [
31] noted that despite students demonstrating the use of metacognitive strategies during L2 reading, their test performance did not exhibit significant improvement. In their study, EFL students underwent an initial English comprehension test, followed by three months of instruction in metacognitive strategies focusing on idea mapping, connecting with background knowledge, and inference-making, before taking a post-instruction comprehension test. Additionally, students participated in interviews to describe how the strategy instruction affected their reading processes. The findings showed that while the instruction did enhance students’ reading awareness, the anticipated improvement in test performance was not observed.
While earlier studies did not explicitly focus on the impacts of question formats, those adopting a variety of question formats for measuring reading test performance suggested that learners may adapt their strategies based on the format of the reading questions. Guterman (2002) [
47] proposed that when learners confront challenging reading questions, such as short-answer questions (SAQs), it stimulates their thinking, prompting them to employ more strategies, particularly metacognitive ones, to improve reading comprehension and test scores. However, findings from studies such as Phakiti (2003) [
18] and Tang and Moore (1992) [
30] present conflicting results. Phakiti observed that the use of metacognitive strategies could enhance L2 reading test scores, whereas Tang and Moore found no significant effect. Notably, neither study found differences in learners’ metacognitive strategy use when tasking with different question formats. As a result, the role of question formats in the relationship between metacognitive strategy use and test performance remains uncertain.
Although prior studies were unable to verify the relationship between metacognitive knowledge, L2 reading test scores, and question formats, researchers have discovered that learners’ L2 reading skills were a stronger predictor of L2 reading test scores than metacognitive strategy use (e.g., [
35,
38,
48,
49]). Schoonen et al. (1998) [
37] and Kim (2016) [
36] further indicated that learners’ L2 proficiency played an important role not only in L2 reading performance but also in the predictive strength of metacognitive strategy use.
Researchers have emphasized the significance of metacognitive knowledge in enhancing L2 reading comprehension. Despite this recognition, studies also indicate gaps in the literature that have yet to be explored. For example, although the relationship between metacognitive knowledge and reading comprehension has been confirmed, studies that focus on exploring the impact of metacognitive knowledge on reading test scores—particularly with regard to question formats—are sparse. Researchers indicated that learners’ L2 proficiency, in comparison to the use of metacognitive strategies, is a stronger predictor of L2 reading test scores [
12,
35,
48,
49]; indeed, it is demonstrable that L2 language competence contributes more heavily to L2 reading test scores when compared to metacognitive knowledge. Studies also indicated that L2 proficiency might help determine whether learners’ metacognitive strategy use benefits reading test scores [
36,
37]. In other words, L2 proficiency may mediate the effects of metacognitive strategies on L2 reading test scores. To address these gaps in the literature, the present study investigated the roles that metacognitive knowledge and L2 language proficiency play in L2 reading assessments regarding question formats (i.e., MCQs and SAQs). With these objectives in mind, the following research questions will be addressed in this study:
What is the relationship between metacognitive knowledge, L2 reading proficiency, L2 reading test performance, and question formats?
How do question formats influence the impact of metacognitive strategies on L2 test scores?
