Reasoning patterns

Machi and McEvoy (2022) describe four distinct reasoning patterns that are essential for constructing a coherent literature review: one-on-one reasoning, side-by-side reasoning, chain reasoning, and joint reasoning. Each pattern serves a unique purpose in organizing and presenting arguments.

One-on-One Reasoning

One-on-one reasoning is the simplest form of argumentation. In this pattern, a single reason is used to support a single conclusion. This straightforward approach is effective when the reason is strong and directly supports the conclusion without the need for additional evidence. For example, if a study finds that a specific teaching method improves student performance, this single piece of evidence can be used to support the conclusion that the method is effective. The simplicity of one-on-one reasoning makes it easy to follow and understand, but it may not be sufficient for more complex arguments that require multiple pieces of evidence.

Side-by-Side Reasoning

Side-by-side reasoning involves presenting multiple reasons (R1, R2, R3, etc.) that independently support the same conclusion. This pattern is useful when a single piece of evidence is not strong enough to support the conclusion on its own. By presenting several reasons, the argument becomes more robust and persuasive. For instance, if multiple studies show that different aspects of a teaching method improve student performance, these studies can be presented side-by-side to collectively support the conclusion that the method is effective. This approach provides a comprehensive view of the evidence, making the argument more convincing.

Chain Reasoning

Chain reasoning, also known as sequential reasoning, involves linking multiple reasons in a logical sequence to support a conclusion. In this pattern, each reason (R1, R2, R3, etc.) builds on the previous one, creating a chain of evidence that leads to the conclusion. This approach is effective for complex arguments that require a step-by-step explanation. For example, to argue that a new teaching method is effective, one might first present evidence that the method improves student engagement (R1), then show that increased engagement leads to better understanding (R2), and finally demonstrate that better understanding results in higher test scores (R3). Chain reasoning provides a clear and logical progression of ideas, making it easier for the reader to follow the argument.

Joint Reasoning

Joint reasoning involves combining multiple reasons that collectively support a conclusion. Unlike side-by-side reasoning, where each reason independently supports the conclusion, joint reasoning requires that the reasons work together to form a cohesive argument. This pattern is useful when the reasons are interdependent and need to be considered together to fully understand the argument. For example, to argue that a teaching method is effective, one might combine evidence that the method improves student engagement, understanding, and test scores. Each piece of evidence contributes to the overall argument, and the conclusion is supported by the combined weight of all the reasons. Joint reasoning provides a holistic view of the evidence, making the argument more comprehensive and persuasive.

In summary, Machi and McEvoy’s (2009) reasoning patterns offer different strategies for organizing and presenting arguments in a literature review. One-on-one reasoning provides simplicity, side-by-side reasoning offers robustness, chain reasoning ensures logical progression, and joint reasoning delivers a comprehensive view. Understanding and applying these patterns can help researchers construct clear, logical, and persuasive arguments in their literature reviews.

Examples

One-on-One Reasoning

1. Example 1: A study finds that students who practice speaking a second language daily show significant improvement in fluency. Therefore, daily speaking practice is effective for improving fluency in a second language.

2. Example 2: Research indicates that children who are exposed to a second language before the age of five have better pronunciation. Hence, early exposure to a second language leads to better pronunciation.

3. Example 3: A survey reveals that learners who use language learning apps regularly score higher on vocabulary tests. Thus, using language learning apps enhances vocabulary acquisition.

Side-by-Side Reasoning

1. Example 1: Multiple studies show that:

   • Students who engage in immersive language experiences improve their listening skills.

   • Learners who participate in language exchange programs enhance their speaking abilities.

   • Those who read extensively in the second language develop better reading comprehension. Together, these studies support the conclusion that immersive experiences, language exchanges, and extensive reading all contribute to overall language proficiency.

2. Example 2: Research findings indicate that:

   • Visual aids help learners remember new vocabulary.

   • Audio recordings improve pronunciation accuracy.

   • Interactive exercises increase grammatical understanding. Collectively, these findings suggest that using visual aids, audio recordings, and interactive exercises enhances second language acquisition.

3. Example 3: Evidence shows that:

   • Bilingual education programs improve cognitive flexibility.

   • Learning a second language enhances problem-solving skills.

   • Multilingual individuals have better multitasking abilities. These pieces of evidence together support the conclusion that second language acquisition has cognitive benefits.

Chain Reasoning

1. Example 1:

   • Learning a second language increases cultural awareness (R1).

   • Increased cultural awareness leads to greater empathy (R2).

   • Greater empathy improves communication skills (R3). Therefore, learning a second language improves communication skills through increased cultural awareness and empathy.

2. Example 2:

   • Regular practice in a second language improves listening comprehension (R1).

   • Improved listening comprehension enhances speaking fluency (R2).

   • Enhanced speaking fluency boosts overall language confidence (R3). Thus, regular practice in a second language boosts overall language confidence through improved listening comprehension and speaking fluency.

3. Example 3:

   • Exposure to a second language at an early age enhances neural plasticity (R1).

   • Enhanced neural plasticity facilitates easier learning of additional languages (R2).

   • Easier learning of additional languages promotes lifelong language learning (R3). Consequently, early exposure to a second language promotes lifelong language learning through enhanced neural plasticity.

Joint Reasoning

1. Example 1:

   • Studies show that interactive language games improve vocabulary retention.

   • Research indicates that group discussions enhance speaking skills.

   • Evidence suggests that writing exercises improve grammatical accuracy. Together, these findings support the conclusion that interactive games, group discussions, and writing exercises collectively enhance second language acquisition.

2. Example 2:

   • Immersive language environments increase exposure to native speakers.

   • Regular feedback from instructors improves language accuracy.

   • Consistent practice sessions build language fluency. Combined, these factors support the conclusion that immersive environments, regular feedback, and consistent practice collectively improve second language proficiency.

3. Example 3:

   • Using multimedia resources makes learning more engaging.

   • Incorporating cultural content increases motivation.

   • Providing personalized learning paths addresses individual needs. Together, these strategies support the conclusion that multimedia resources, cultural content, and personalized learning paths collectively enhance the effectiveness of second language acquisition.
