INTRODUCTION

With an increased focus on language ability for communicative and economic reasons, language education is a crucial part of global education. Language learning research has developed throughout time, with quantitative study designs becoming as the most popular technique for examining language acquisition characteristics. Quantitative research is very helpful for examining the impact of different language learning treatments, assessing the link between language learning factors, and forecasting language learning outcomes. This essay will look at a few of the most popular quantitative research techniques used in language teaching and their applicability to the study of language acquisition.

Quantitative research designs are frequently used in language education to examine a variety of language learning topics, including the effects of different teaching methods, the connection between academic achievement and language proficiency, and the motivational factors for language learning. To draw conclusions regarding the issue under investigation, most study strategies depend on the gathering and statistical analysis of numerical data.

Language education regularly makes use of a number of quantitative research designs, including experimental, quasi-experimental, survey, correlational, and longitudinal research. Each design has pros and cons, and the choice of design depends on the research question and the availability of participants.

For examining factors associated to language learning in language education, quantitative research approaches are helpful. These data collection and analysis approaches are methodical and thorough, and they may help us learn more about the procedures and results of language acquisition.

QUANTITATIVE RESEARCH DESIGNS

Quantitative research designs are empirical research methods that involve the collection and analysis of numerical data to assess hypotheses or provide answers to research queries. Listed below are some of the most prevalent quantitative research designs:

In an experimental design, participants are randomly assigned to an experimental or control group, and the effects of a manipulated independent variable on a dependent variable are measured.

Quasi-experimental design: Quasi-experimental designs are similar to experimental designs, but participants are not randomly assigned to groups. Instead, existing groups or conditions are utilized, and the independent variable is manipulated or observed to determine whether or not it influences the dependent variable.

Quantifying the link between two or more variables using a correlational design prevents the variables from being changed. The degree and direction of the association between two variables are assessed using the correlation coefficient.

A survey design gathers data from a sample of individuals using questionnaires or interviews. One may analyze the correlations between variables or describe the traits of a group using survey data.

In a longitudinal design, the same participants’ data are gathered over a longer period of time, such as months or years. Researchers may look at how variables change over time and identify their reasons thanks to this arrangement.

In a cross-sectional design, information is gathered from participants of diverse ages or groups all at once. This design may be used to examine the differences between groups or to describe a population’s characteristics.

Each research design has benefits and drawbacks, and the choice of design is influenced by the research topic, the types of variables being examined, and the resources that are available.

EXPERIMENTAL DESIGN

An extremely efficient method for identifying the cause-and-effect connections between variables is experimental design. In order to examine the impact on a dependent variable, the researcher manipulates one or more independent variables after randomly assigning participants to different treatment groups. In order to examine the effects of an independent variable on a dependent variable, an experimental design involves randomly assigning individuals to either an experimental group or a control group. The comparison group serves as a control and is not given the intervention or therapy, whereas the experimental group does. An experimental design aims to ascertain if the independent variable significantly affects the dependent variable while controlling for unimportant factors.

A crucial component of experimental design is random assignment. Each participant has an equal chance of being allocated to any treatment group because to random assignment. This reduces the possibility that any observed effects are the result of coincidence or other unrelated causes and assists to account for participant individual variations.

Numerous academic fields, including psychology, education, and health, may benefit from experimental design. For instance, in a study on language teaching strategies, researchers may at random assign individuals to computer-assisted learning or conventional classroom instruction, and then compare how well they performed on language exams (Campbell & Stanley, 2015).

One benefit of the experimental design is that researchers may demonstrate causal correlations between variables. By changing the independent variable and adjusting for unrelated factors, researchers may ascertain if changes in the independent variable result in changes in the dependent variable. This may improve our knowledge of the correlations between factors and help find successful therapies.

An iconic illustration of an experimental design is Zimbardo’s 1971 Stanford Prison Experiment. College students were randomly assigned to the roles of “prisoners” or “guards” in this experiment, and they were then put in a mock prison environment. Participant behavior was the dependent variable, whereas participant role assignment was the independent variable. The findings showed that the participants’ assigned positions had a major impact on how they behaved, and that the hostages were treated abusively and with authoritarian conduct by the guards.

However, there are other limits in the experimental design. The ability or morality to control certain factors may not always exist. To evaluate the impact of smoking on health, for example, randomly assigning people to a smoking group would be unethical. Researchers may be compelled to use observational or quasi-experimental designs in these circumstances (Cook, Campbell, & Shadish, 2002).

In comparison to other research methods, experimental designs provide a number of benefits, including the ability to demonstrate cause-and-effect correlations and the capacity to control for irrelevant factors. The experimental approach does, however, have several drawbacks, including the potential for demand characteristics and the moral issues raised by altering variables.

QUASI-EXPERIMENTAL DESIGN

In the same way that an experimental design aims to identify cause-and-effect correlations between variables, a quasi-experimental design is a kind of research design. Participants are not divided into groups at random, contrary to the study design. Instead, pre-existing conditions or groups are employed, and the independent variable is adjusted or tracked to determine whether it affects the dependent variable.

The study by Albino (2017), which examined how task-based language teaching (TBLT) improved the speaking fluency of ninth-grade EFL students at PUNIV-Cazenga High School in Luanda, is an illustration of a quasi-experimental design in language education. Before and after the 8-week teaching intervention, which included the use of feedback tools including recasts and prompts, learners’ picture-description tasks were audio recorded as part of the research’s case study methodology. According to the study’s findings, learners’ speaking fluency greatly increased by increasing their rate of speech production, increasing grammatical correctness, lengthening their utterances, and honing their interactional language abilities. The students also acknowledged their appreciation for the TBLT method, feeling encouraged to speak, certain in their proficiency with the language, and appreciating its importance for vocabulary growth. It is explained how the study may affect future research and instructional practice.

The goal of Pham et al.’s (2020) investigation was to ascertain the impacts of two different peer commenting activity modalities on students’ writing quality. The study used a control and experimental group quasi-experimental research design. The participants were 72 Vietnamese native students from two complete courses at the Ho Chi Minh City University of Science who had prior training experience. The only variation between the training processes for the two groups was the kind of peer comments. Peer reviews of articles were undertaken in one group in person and in the other through the Facebook social network. Inter-raters collected the pre- and post-tests, which were then scored. The results were then examined using t-tests in the SPSS program. According to the study’s results, the two types of peer criticism activities had a big influence on how well children wrote. Peer e-comments on Facebook, however, fared better than more conventional face-to-face peer comments in the group that utilized them. This implies that the manner of peer commenting might affect students’ writing abilities and that using online platforms like Facebook for peer comments may be more successful in raising writing quality than using conventional face-to-face techniques.

In certain circumstances when random assignment is impractical or unethical, the quasi-experimental approach may be more practical and viable than the experimental method. The quasi-experimental method, however, also has certain drawbacks, such as the possibility of selection bias and the lack of control over auxiliary variables.

CORRELATIONAL DESIGN

Correlational research approach is often used in language education to examine the connections between variables. It is the process of figuring out how two or more variables relate to one another without changing the variables themselves. The degree and direction of the association between two variables are assessed using the correlation coefficient.

In order to determine the relationship between phonological and morphological awareness in English (L1)-Arabic (L2) bilingual children in Canada (N = 43), as well as the significance of these abilities to word and pseudoword reading accuracy and complex word reading fluency, Saiegh-Haddad and Geva (2008) conducted an exploratory study. However, morphological awareness was not significantly correlated with either English or Arabic phonological awareness, according to the research. It was shown that whereas Arabic morphological awareness only predicted correct word reading in English, phonological awareness predicted reading ability in both languages. Additionally, only phonological knowledge was shown to predict Arabic reading, while both morphological and phonological awareness predicted unique reading variance in English. Finally, it was shown that phonological awareness was the sole component that predicted accurate pseudoword decoding in both languages, although morphological awareness predicted reading fluency with complex words in both languages. The authors addressed these results in terms of differences in orthographic depth, morphological structure, and transparency between English and Arabic.

Another example of a correlational design in language education is Lyster and Mori’s (2006) study of the connection between corrective feedback and second language learning. The frequency and nature of corrective feedback, as well as the correctness of French as a second language among English-speaking students, were examined using a correlational design by the researchers. Recasts may be a useful type of corrective feedback in the learning of a second language, according to the researchers, who found a strong positive link between the frequency of recasts and the correctness of French.

The correlational design, which may be used to look at correlations between uncontrolled factors, has several benefits over other study methods in language teaching, such the experimental design. The likelihood of third-variable effects and the difficulty to demonstrate causation are two drawbacks of correlational designs.

SURVEY DESIGN

A common study technique in language education is the survey design, which uses questionnaires or interviews to gather data from a sample of participants. Data from surveys may be used to investigate correlations between variables or to characterize a population.

A research by Nasri, Shafiee, and Sepehri (2021) aims to evaluate the motivation and attitude of Iranian EFL learners toward studying English in a CALL setting and serves as an example of survey design in language education. 120 intermediate EFL students from two private English language schools in Isfahan, Iran, participated in the research. They were split into two groups for the study: an experimental group (EG) and a control group (CG). To gauge the participants’ motivation at the start of the course, a motivation questionnaire pretest was given to both groups. While the CG was instructed conventionally, the EG got CALL-based instruction. After that, both groups received an attitude survey and a posttest on motivation. The findings showed that, as judged by the Motivation Questionnaire, the participants’ motivation greatly rose as a consequence of the CALL-based education. A 20-item A-CALL attitude questionnaire revealed that the learners in the EG had favorable opinions regarding adopting CALL-based training. Numerous conclusions and suggestions for further study are drawn from the data.

In terms of collecting data from a large sample of participants quickly, assessing participants’ attitudes, views, and perceptions, and extrapolating results to a larger population, surveys have a number of benefits in the field of language education research. Inadequate control over the data gathering process, possible response bias, and the difficulty to show causation are some of the drawbacks of survey design.

LONGITUDINAL DESIGN

A longitudinal design is a kind of study that gathers data from the same individuals over a protracted period of time, often months or years. The growth and evolution of language ability, language learning techniques, and language attitudes throughout time may be studied using this methodology in language education research. Researchers may discover causal correlations between variables and investigate how these interactions evolve over time using longitudinal methods.

A research by Busse, V., and Walter, C. (2013) provides an example of longitudinal design in language teaching. The research focuses on motivation and analyses first-year students’ experiences in German degree programs at two prestigious UK institutions. The research investigates the changes in motivation and effort of these students over the course of a year using a longitudinal mixed-methods methodology. The findings reveal that despite the students’ desire to become proficient in German, their engagement with language learning decreased throughout the year, alongside a decrease in intrinsic motivation and self-efficacy beliefs. The study discusses the relationship between these motivational changes and contextual factors in higher education, particularly the students’ transition experience from school to university. The article concludes with suggestions for educators on how to address decreasing motivation among modern foreign language students during their first year of university studies.

Another example of longitudinal design in language education is a study by Huang et al.’s (2020) study which aimed to investigate two objectives: (1) to examine the impact of input on the long-term second language (L2) outcomes of bilingual adolescents in a minority/foreign language setting, and (2) to comprehend the relationship between input and other factors that may affect L2 outcomes such as environmental variables, motivation, and language learning aptitude. Between the ages of 2 and 11, 97 Taiwanese adolescents who were multilingual in Mandarin and English as their second language participated in the research. Along with two standardized language learning aptitude tests, participants also had to complete an English story-telling and listening comprehension exercise. Long-term L2 listening comprehension results were significantly influenced by input, but not speech production outcomes, according to correlation and multivariate regression analyses. The results also indicated that contextual factors and ability for language acquisition were important indicators of long-term L2 outcomes. Since prior research were mostly done in a majority/societal language environment, the study advances our knowledge of the function of input in L2 learning in a minority/foreign language situation.

It is possible to evaluate changes in variables over time, establish causal linkages between variables, and perhaps find characteristics that predict language learning outcomes, all of which are benefits of longitudinal designs in language education research. However, longitudinal designs also have major drawbacks, including the possibility of participant attrition, the significant financial and time commitment needed, and the possibility that outside factors may affect the outcomes.

CROSS-SECTIONAL DESIGN

An approach of doing research known as a cross-sectional design includes gathering information from participants all at once, usually from several age groups or groups with various characteristics. Research on language instruction may examine group differences and characterize demographics using this methodology.

Ramos (2010) used a cross-sectional survey to examine the perspectives of 218 K–8 teachers on the use of native language education for kids who speak a language other than their own. The results show that although the underlying theory has great acceptance, its actual application is less so. The research also examines the variables that affect instructors’ perspectives and changes across grade levels. Strong support is found for the theoretical underpinnings of native language education, which is consistent with prior studies, but less strong support is found for its actual execution. No definite predictors of views have been established, and there are no discernible differences in opinions across grade-level groupings. The findings imply that teachers’ ideas shape their perspectives, underlining the necessity for more study and taking into account instructors’ individual viewpoints, comments, and input while developing teacher training programs.

A research by Collette and Miller (2019) that explores how cultural elements create social influence and starts by looking at source factors including credibility, power, power distance, and minority influence is another example of a cross-sectional design in language teaching. The form of a persuasive message may also have an impact on its potency. Cross-cultural research has demonstrated that whereas individualistic societies employ logic, argument, and evidence, collectivist cultures often emphasize the process. As a result, message elements have various impacts on different cultures. The chapter also covers group dynamics and how they affect more universal but potentially less effective persuasion mechanisms like reciprocity and scarcity. The chapter concludes by examining how cultural values affect how we respond to and oppose persuasive arguments and how this might vary between cultures.

In language education research, cross-sectional designs offer various benefits, including examining group differences and outlining a population’s characteristics. The possibility for cohort effects, which happen when variations across groups are caused by reasons other than age or features of the groups, such as historical events or societal changes, is one restriction of cross-sectional designs.

CONCLUSION

The many study designs that are often used in studies on language instruction have been covered in this section. Explanations of the experimental, quasi-experimental, correlational, survey, longitudinal, and cross-sectional designs have been given, along with examples of research that have employed each of these approaches.

In experimental designs, people are divided into groups at random, and an independent variable is changed to see how it affects a dependent variable. Similar to experimental designs, quasi-experimental designs employ preexisting groups or conditions and watch or alter the independent variable to determine whether it affects the dependent variable. Without modifying the variables, correlational designs quantify the connection between them, while survey designs gather information via questionnaires or interviews. Cross-sectional designs gather information from participants at a single moment in time from several groups, while longitudinal designs gather information over time from the same people.

The research topic and the variables under investigation determine the best research design to use. Each research design has advantages and disadvantages. These designs are used by language education researchers to look at a variety of subjects, including language learning, attitudes about language, language usage, and instructional strategies. Researchers may get insights into the complicated nature of language and its function in society by adopting proper study designs.
