Online learning environments
Online learning environments have emerged as a supportive and sometimes alternative environment for learning since 2001 (Olivier & Liber, 2001). Kumar Basak, Wotto & Bélanger (2018) explained that online or e-learning, mobile learning (m-learning) and digital learning (d-learning) are used interchangeably or complementarily to mean technological learning, which emerged as the alternative to traditional education or could be used to complement it, integrate it or replace it. E-learning supports traditional learning through electronic tools and media (Hoppe, Jointer, Milrad & Sharples, 2003). It is facilitated in online learning environments by digital technology, which facilitates instructional practice and effectively uses technology for learning (Kumar Basak et al., 2018).
As such, an online learning environment is defined as a platform, a design or a programme with an interface that allows learners to access and interact with the e-course - a digitally designed syllabus and material for learning and learner evaluation uploaded to a secure, login-supported environment (Müller & Strohmeier, 2010). It was also recognised as a software designed to manage the learning process and regulate synchronous and asynchronous learning and interaction between teachers and learners as well as learners and learners. Therefore, such platforms are described as learning management systems with virtual learning supports and tools made available online through login credentials for free or a paid subscription (Arkorful & Abaidoo, 2014; Weaver, 2008).
An e-learning environment is a virtual place for modifying and changing learners' behaviours and performance using a specific learning software or a platform to which an e-course is uploaded. Therefore, such an environment is made up of three main components: 1) individual performance, including learners, teachers and peers or teamwork; 2) learning materials, including videos, pdfs, graphics and other technologically designed learning material; and 3) the interaction between individuals in this environment through messaging, discussion, debates, commentary and opinion sharing, all of these being practised in a computerised environment involving hi-tech programmes and e-course management systems (Rashad, 2010).
Preliminarily, e-learning was used as a supportive alternative to traditional classroom learning until soon when the COVID-19 pandemic struck the world and made resorting to e-learning a must (Al-Oteibi & Al-Abdelli, 2020; Othman, Al-Allawendi, & Farahat, 2020). Researchers and educational practitioners could adduce that such environments, like Google Classroom, a free e-learning platform or Blackboard® or Edmodo®, two paid platforms, could enable course designers and instructors to modify e-course content at low costs and efforts, boost the instrumental motivation for learning and achievement, provide learners with the opportunity to be self-independent or peer or team-learners. Such environments also help teachers to vary the experiences of learning in virtual reality, which helps in improving learners; thinking skills and language learning skills independently of the role of the teacher. According to Khan (2005), the type of e-learning transitioned through online learning environments is open-access, distributed and flexible, lending to the moulding of an active, interactive, analytical and critical learner grounded in the learning theories of behaviourism, cognitivism and constructivism (as shown in Fig. 1 below):
Participation in e-learning environments is typically measured by the learners' activities in discussion forums and message exchanges between peers and themselves and between learners and teachers (Küçük et al., 2010). In line with the constructivist approach, online discussion forums depend on the idea that students can learn as much from one another as from course materials or instructors. In a discussion forum, a participant can have opportunities to express ideas, have them criticised, reshape ideas in light of peer discussions (Kilinc & Altınpulluk, 2021), and offer feedback on others’ ideas. This exchange of ideas and works helps students engage in higher-order information processing and construct their meanings.
Cognitive styles
Cognitive styles refer to individuals' preferences to organise and process information and learning experiences. In contrast, learning styles, a similar construct, refer to individual skills and preferences that affect how learners perceive, collect and process learning materials (Sadler-Smith, 2001). Educators used to conceive of the two constructs as synonymous, and they used them interchangeably, but both terms have nuances in meaning and use (Dörnyei & Ryan, 2017). A cognitive style is congenital and is set from birth, describing how one processes information cognitively in the brain. Thus, it is distinctively descriptive of a person. In contrast, a learner style refers to how an individual approaches knowledge and experiences and interacts with and responds to learning material in a given learning environment (Li, 2022).
A well-known and accepted theory of learning styles is that of Fleming's VARK, in which learning styles were classified into three categories: visual learners, auditory learners and kinaesthetic learners; learning styles assume that learners approach information in ways that are consistent with their preferred learning modes (Fleming & Baume, 2006). On the other hand, cognitive styles are manners or strategies people use distinctively for receiving, processing and responding to information, thus being specifically related to information processing, retrieval and retention. Cognitive styles, therefore, make for individual variations and differential aspects of learners at the levels of cognition, affect and motivation (Popa, Țepordei, Labăr & Frumos, 2018). According to Bendall, Galpin, Marrow & Cassidy (2016), cognitive styles are methods used by individuals in dealing with the stimuli they are exposed to in their different life situations, which helps to reveal the differences between individuals not only in the cognitive field such as perception, remembering, thinking, forming concepts, learning, constructing and retaining information, but also in the affective and emotional field, the social field and the study of personality; thus distinctive cognitive styles of individuals are interpreted in light of the methods of activity that they practice, regardless of the content of this activity (Panadero, 2017).
Researchers explained that cognitive styles are characteristically descriptive of a cognitive activity framework and are learning situation-related but are not restricted to the learning or experience content; therefore, cognitive styles are related to individual differences as to how to practice cognitive processing, such as thinking, perceiving, retaining and retrieving information, problem-solving and handling and developing information (Panadero, 2017). Cognitive styles are relatively stable and flexible but are not easily prone to change, which helps predict how individuals behave cognitively in learning situations and environments (Dai, 2014; Kozhevnikov, Evans & Kosslyn, 2014; Zhang, Sternberg & Rayner, 2012). However, they can generally be directed or guided as comprehensive personality descriptors. Cognitive styles can be assessed verbally or non-verbally, and they are determined by the sociocultural backdrop and the socio-educational milieu in which a person lives, suggesting that cognitive styles reveal the heuristics that people use to process information about their environment. According to researchers, cognitive styles can be classified into several bipolar styles: context dependency vs interdependency, rule-based vs intuitive processing, internal vs external locus of processing, and integration vs compartmentalisation (Kozhevnikov, 2007).
Kozhevnikov et al. (2014), reviewing the first large-scale experimental study by Witkin, Moore, Goodenough & Cox (1977), indicated that field-dependent individuals rely on the surrounding context, and field-independent individuals do not depend on their surrounding environment; therefore, researchers reported a relationship among participants' performance on perceptual tests, their personality characteristics, and their social behaviour' (Kozhevnikov et al., 2014, p. 6). Furthermore, field-dependent individuals are more observant of social cues than are field-independent individuals; in addition, field-independent individuals tend to entertain a more impersonal orientation than do field-dependent people, thus seeking to keep a psychological or even a physical distance from their peers (See Witkin & Goodenough, 1981, and Kozhevnikov et al., 2014 for a comprehensive review).
The core of cognitive styles theories is deeply grounded in an individual's innate predispositions where the opposite poles of the field-dependence/independence style dimension characterise the products of the diverse modes of physical adjustment and cognitive adaptation to the world (Kommers, Stoyanov, Mileva and Martinez, 2008). Learning styles are environmentally sensitive. Therefore, learners would exhibit individual differences in cognition and learning (Kozhevnikov et al., 2014). Early research in education investigated cognitive styles based on individual differences in perception and concept formation, the lower-order cognitive processes, while more recently, the focus has been on learning styles or the higher-order cognitive functioning such as hypothesis formation, problem-solving and modelling (Evans & Cools, 2011; Evans & Waring, 2013; Evans & Kozhevnikov, 2013; Rayner & Cools, 2011; Peterson, Rayner, & Armstrong, 2009).
Educational research also provided empirical evidence indicating that the learning environment influences the poles of dependency versus independency of context. For instance, the context-independent learner is more capable of analysing situations, retrieving information, and organising the elements of learning material. The locus of control is internal when dealing with the elements of the external situation, and where an individual prefers learning through written or oral verbal language and gets high scores on tests that depend on perception and understanding. However, a context-dependent learner is characterised by full awareness of the learning material, prefers to deal with topics that are presented in an orderly manner, and also prefers learning through audio-visual materials, thereby tending to get lower scores than the context-independent learner, especially on tests that rely on memorisation and understanding, as such individuals fail to deal with too much information (Kollöffel, 2012; Kommers et al., 2008; Menaker & Coleman, 2007).
Several tests contribute to the classification of individuals according to the cognitive style of context-independence versus context-dependence; for example, Witkin, Dyk, Faterson & Karp (1962) introduced the Group Embedded Figures Test (GEFT), which assesses the field-dependence/independence dimension, an Arabic version of the Group Embedded Figures Test standardised by Al-Sharkawi (Version V, 2013) was used in the present study to classify the sample into context-dependent and context-independent participants. The GEFT inventory is comprised of three sections; section (1) training, yet the score of this section is not calculated in the examinee's assessment, and it consists of seven easy ways to do paragraphs; section (2) consists of nine paragraphs of graded difficulty; and section (3) consists of nine paragraphs of graded difficulty as well. This section is considered equivalent to the second section of the GEFT. Each paragraph in the three sections is a compound form with a simple form inside. The learner is asked to define the boundaries of the simple form inside the complex shape in pencil, and the simple shapes that the learner is asked to discover and set their borders are printed on the last page of the GEFT. The GEFT is designed in a way that the learner cannot see the simple form within the complex form that it contains at the same time, and each section of the test has a specific time to do: two minutes for the first section, five minutes for the second section, five minutes for the third section. The researchers restricted the test timing and the answer key associated with the Arabic version of the GEFT.
Instrumental motivation
Instrumental motivation, also called motivation for achievement, is a type of motivation that drives an individual to perform a specific action or behaviour in order to achieve a particular goal or reward. It is a form of extrinsic motivation, comprising four essential components, namely: 1) self-confidence, including one's preparedness and predispositions, and the potential for work, which qualify one to achieve their goals and accomplish the tasks entrusted to them; 2) mastery for perfection that requires perseverance and effort individually pursued without relying on others; 3) independence or the ability to work independently of others, grounded in one's belief in their abilities; and finally 4) ambition and striving for excellence (Mattar, 2013).
According to Lens, Paixão, & Herrera (2009), instrumental motivation is generally sought after in educational settings. It is correlational or cross-sectional, where learning is not a goal per se, but an instrumental activity in the learning environment is what makes this type of motivation matter; individuals entertain instrumental motivation because it will have positive consequences in the future, such as to be able to adapt to the learning environment or pass exams (Lens et al., 2009, p. 24). Unlike cognitive styles, instrumental motivation is not a static construct; it can be developed and changed across domains, contexts, or activities (Nizam et al., 2021; Ryan & Deci, 2000). Prior research demonstrated " a positive and significant correlation between academic motivation and academic achievement" (Nizam et al., 2021, p. 280).
Vocabulary learning: retrieval and retention
The role of vocabulary in EFL learning is indispensable and indisputable, with vocabulary being the flesh of the language system (Wang, Gwo-Jen Hwang & Ma, 2020). Harmer (1991) argues that "If language structures make up the skeleton of language, then it is vocabulary that provides the vital organs and the flesh" (p. 153). Vocabulary learning represented in the interdependent cognitive processes of retrieval and retention is significantly difficult (Chen & Chung, 2008; Ebbihaus, 1913); however, if the learning environment contains images or graphics, videos and other mnemonics, vocabulary learning tends to transition from the short-term working memory to the long-term memory (Driscoll, 2005). However, conventional vocabulary teaching/learning is often restricted in terms of both class time devoted and effective retention strategies used since learners need to primarily be self-dependent in their vocabulary learning - a process that possibly poses problems and frustration for learners, eventually resulting in their loss of motivation (Dörnyei & Csizér, 2002).
Therefore, the literature review suggests using online learning environments that capitalise on multimodal presentation and spaced repetition to help students successfully learn vocabulary, retrieve it and retain it when needed (Kohnke, 2019). The use of multimedia entails lexical understanding and retrieval, as suggested in the Cognitive Theory of Multimedia Learning (Kohnke, 2019; Wang et al., 2020). Additional research is yet needed to explore this effect of online learning environments on vocabulary learning and hence the rationale for conducting this study.
