This paper examines two influential articles in the field of adult learning: Stephen Lieb's "Adults as Learners," which outlines the core principles of andragogy as advanced by Malcolm Knowles, and Stephen Brookfield's "Issues in Understanding Adult Learning," which critically challenges several foundational assumptions of adult learning theory. The paper summarizes each article's key arguments, compares their perspectives on self-direction, motivation, critical reflection, and experiential learning, and concludes by discussing the combined impact of both works on training and development practice. Together, the articles offer both practical guidance for instructors and important cautions for researchers in the field.
The paper demonstrates comparative analysis of secondary sources. Rather than simply summarizing two articles, it places them in dialogue with each other, identifying where their assumptions align and where they conflict—particularly on self-directed learning, the value of experience, and critical reflection. This technique is fundamental in literature review and analytical writing at the undergraduate level.
The paper opens with a definition of andragogy and its distinguishing assumptions. It then devotes a section each to Lieb and Brookfield, covering their main arguments in depth. A brief comparative section synthesizes the two views, followed by a discussion of practical implications for training and development professionals. A short conclusion gestures toward future research needs. The structure is straightforward and appropriate for a comparative essay of this scope.
Andragogy is the term used for the theory of adult learning. The theory was developed because experts in the field of learning recognized that educating young students produces an entirely different set of circumstances and needs than educating adults does. Students who are not yet adults bring very little to the table by way of life experience, and the education path is significantly more instructor-driven than adult learning situations tend to be (Noe, 2004). For this reason, the adult learning theory was created.
The theory provides several assumptions that differ from the majority of educational theories, including the belief that adults have a need to understand why they need to learn the material presented to them, that adults have a need and desire to self-direct in the learning process, that adults often bring work-related experience to the learning environment, and that both extrinsic and intrinsic motivation come into play with regard to adult learning (Noe, 2004).
The importance of understanding adult learning theory cannot be overstated with regard to training and development, as this understanding helps educators develop programs conducive to the adult learning process.
In the article "Adults as Learners," Stephen Lieb takes the reader through a discussion of how adults seem to learn most effectively. Lieb provides characteristics of adult learners that he attributes to one of the pioneers of adult learning theory, Malcolm Knowles. These characteristics include the following:
Adults are autonomous and self-directed. They need to be free to direct themselves. Their teachers must actively involve adult participants in the learning process and serve as facilitators rather than lecturers. Specifically, instructors must seek participants' perspectives about what topics to cover and allow them to work on projects that reflect their interests. Instructors should allow participants to assume responsibility for presentations and group leadership, and they must act as facilitators, guiding participants toward their own knowledge rather than simply supplying them with facts. Finally, instructors must show participants how the course will help them reach their personal goals (Lieb, 1991).
Lieb points out that adults have had a lifetime of experiences that have helped shape who they are, and that these experiences are often varied, encompassing work-related situations, family responsibilities, and prior educational achievements. Because of the many and varied experiences adults bring to the learning environment, Lieb believes it is important for them to be able to connect new learning back to previous experiences and to understand how new learning will affect future situations.
Lieb also argues that research has demonstrated that adults are goal-oriented, relevancy-oriented, and practical, as compared to younger learners. He identifies motivation as a key factor in adult learning theory and lists six different sources of motivation: external expectations, social welfare, personal advancement, escape or stimulation, and cognitive interests.
While children have a single-minded obligation to absorb what they are being taught, Lieb notes that adults are constantly bombarded with outside responsibilities that compete for their attention and can interfere with the learning process. He argues that the best way to motivate adult learners is to enhance their reasons for enrolling and to decrease the barriers to learning. Instructors must understand why their students have enrolled, discover what obstacles prevent them from learning, and then plan motivating strategies accordingly. A successful strategy, for example, includes showing adult learners the relationship between a training program and an expected promotion (Lieb, 1991).
Lieb also provides practical tips for instructors of adults regarding motivation and retention, with the goal of helping learners retain new information more effectively. Another important concept he addresses is transference — the ability to apply information learned in a course to a new setting. As with reinforcement, Lieb identifies two types of transfer: positive and negative (Lieb, 1991).
In his article "Issues in Understanding Adult Learning," Stephen Brookfield challenges the concept that adults have a radically different pattern, style, and willingness to learn compared to the way children and adolescents learn. Brookfield argues that believing there is such a significant difference between adult and child learning is a "grave" error on the part of the education field, and that educators would be better served by focusing on individual learning styles, cultures, and personalities (Brookfield, n.d.).
Brookfield provides evidence that self-directed learning as an adult preference was, for a time, being advanced without critical scrutiny, which he argues dilutes its credibility as a science-based fact. Eventually, self-directed learning was separated from broader pedagogical discussions in adult learning theory development. Brookfield cautions: "More longitudinal and life history research is needed to understand how periods of self-directedness alternate with more traditional forms of educational participation in adults' autobiographies as learners. The extent to which a disposition to self-directedness is culturally learned, or is tied to personality, is an open issue" (Brookfield, n.d.).
Brookfield also critically targets the term critical reflection as it pertains to adult learning, calling it the "idea of the decade" in his article. He suggests that educators adopted the term in order to attribute a specific form of learning to adulthood, thereby providing justification for a separate adult learning theory. He states that "many tasks remain for researchers of critical reflection as a dimension of adult learning. A language needs to be found to describe this process to educators which is more accessible than the psychoanalytic and critical theory terminology currently employed" (Brookfield, n.d.).
Brookfield also addresses the notion of experiential learning as it evolves into music, games, and other methods for teaching curriculum to adults. He acknowledges the theory's belief that the longer one has lived, the more experiences one accumulates and the more those experiences can be applied to learning new material. However, he reminds the reader that a single experience can be every bit as valuable as thirty years of experience when it comes to applying prior knowledge to new learning (Brookfield, n.d.).
In summarizing his position, Brookfield calls for further, more in-depth research in the field of adult learning. He also insists that a more narrowly defined set of terms must be established for adult learning studies so that the ideas emerging from research can be critically evaluated with consistency (Brookfield, n.d.).
Applying Lieb's guidelines — such as involving adult participants in goal-setting, connecting new content to existing experience, and reducing barriers to motivation — can lead to more effective workplace training outcomes. At the same time, heeding Brookfield's call for more rigorous research and standardized terminology can help the field mature into a more scientifically credible discipline.
As adult education continues to expand through online platforms, classroom learning, and on-site instruction at the workplace, understanding how adults process information will remain critically important. Applying the practical guidance offered by Lieb can help instructors deliver new material more effectively to adult learners. At the same time, taking Brookfield's concerns seriously and subjecting adult learning assumptions to ongoing scrutiny will be equally valuable.
It will be important to determine which of these perspectives proves most accurate as future adult education programs continue to develop and the demand for learning expands to a global scale.
