Effective Writing for English Academic Papers: The CARS Model


As an English academic writing professor, my goal is to help students improve their writing skills and produce compelling and informative academic papers. One crucial aspect of academic writing is understanding the CARS (Creating a Research Space) model, which consists of three moves: Move 1 – establishing a research territory, Move 2 – establishing a niche, and Move 3 – occupying the niche. In this article, we will examine a hydrogel-based material for oral drug delivery as an example of the CARS model in action.

Move 1 – Establishing a Research Territory

The first move in the CARS model is to establish a research territory. This move provides background information to the reader about the topic being studied. In the example of hydrogel-based material for oral drug delivery, the author begins by discussing oral delivery as the most commonly used method for drug delivery. The author briefly mentions the advantages of oral delivery before addressing the drawbacks and limitations. This discussion prepares the reader for Move 2, where the author will examine the current state of research in the field.

Move 2 – Establishing a Niche

The second move in the CARS model is to establish a niche. This move examines the current state of research in the field and highlights the need for further study. In the example of hydrogel-based material for oral drug delivery, the author uses references to previous research to describe the challenges and difficulties of using oral delivery. The author then proposes a new method to address these issues and overcome the limitations of oral delivery. This move highlights the significance of the current research and establishes its importance in the field.

Move 3 – Occupying the Niche

The third and final move in the CARS model is to occupy the niche. This move explains the new method proposed by the author and how it addresses the identified problem. In the example of hydrogel-based material for oral drug delivery, the author proposes the use of hydrogel as an ideal material for drug delivery due to its sensitivity to pH value. The author convincingly argues why hydrophilic pH-sensitive hydrogel is an ideal material for oral administration of drugs.


In conclusion, understanding the CARS model is crucial to producing a logical and compelling academic paper. By establishing a research territory, examining the current state of research in the field, and proposing a new method to address the identified problem, writers can create a well-supported and convincing argument. In addition to the CARS model, writers should also follow the G-S pattern of writing, starting with general information and gradually narrowing down to specific details. With these tools, writers can produce academic papers that are informative, engaging, and well-structured.
