Discovery-Based Instruction Enhance Learning? Allusions

¶ … discovery-Based instruction enhance learning? Allusions to the Virtue of Guided Discovery-Based Learning The merits of discovery-based learning have been debated for nearly as long as this approach towards learning has been popularized. A number of specific research studies have been conducted to validate the efficaciousness of discovery-based learning, including that authored by Louis Alfieri et al.

entitled "Does discovery-based instruction enhance learning?." In order to properly analyze the research and findings conducted within this article via a synthesis of other articles that either corroborate or disprove its conclusions, it is necessary to provide a brief overview of the history and attempts of discovery-based learning. This educational technique was widely pioneered in the middle part of the 20th century, and was based upon the notion that unstructured learning via individual (and perhaps even small group) discoveries would positively impact the process and retention of obtaining knowledge.

Discovery-based instruction places a greater emphasis on the role of the student for the responsibility of facilitating his or her own knowledge, through a process which was believed to be as valuable as that of the actual results of obtaining knowledge. The true value of relying upon limited instruction while facilitating instruction for students has been questioned via the traditional methods of instructor-based learning. The research conducted by Alfieri et al.

was stratified into a pair of meta-analyses, the first of which compared the results of unassisted discovery learning with the results of conventional instructional learning. The second meta analyses compared the results of two different types of discovery-based learning, one of which was unstructured and the other of which was significantly more structured.

The results of the research provided within this article, as well as those from other articles elucidating the merits of discovery-based learning, indicate that instruction and guidance plays an integral role in effective learning for students at most levels. Objective Measurable Analyses The most logical place to begin examining the empirical evidence for the veracity of the proclivity to employ discovery-based learning due to its efficaciousness is via the data compiled by Alfieri et al.'s report.

For the first meta analyses, there were 108 studies that yielded 580 comparisons that demonstrated that instructional teaching methods are more beneficial to learners than discovery-based methods that are unassisted. Significantly, the data in this article also indicated that 56 studies yielding a total of 360 comparisons demonstrated that guidance methods of discovery were more effective for learning than unassisted discovery-based learning. The implications of these findings are fairly significant. These findings imply that students actually benefit more from pedagogical methods with instruction more than those that rely less upon instruction.

An analyses of the empirical data from a study conducted by Flores and Kaylor supports this viewpoint. In this particular study, the researchers compared a basal method of teaching vs. An instructional-based method on seventh graders who could not pass a state required math course. The research method utilized within this study involved administering a pretest and a posttest to 30 such students -- with the assumption being that when students took the pretest, they were utilizing the knowledge they had learned via the basal method.

The basal method of instruction incorporates some elements of discovery learning, as students have a fair amount of autonomy with certain assignments and license to learn on their own. The posttest was administered after students had engaged in eight weeks of rigorous instruction-based learning pedagogy. The results of the data, which issued a 16.224 t-test score at the .005 level, largely demonstrated that students significantly improved through the usage of the instruction-based learning.

Although discovery-based learning was not explicitly compared by this study, the merits of instruction-based learning are fairly apparent and suggest that they are more beneficial to students than discovery-based pedagogy. What is perhaps most important to denote regarding the research performed by Alfieri et al. is that there is actually a distinction between types of discovery-based learning.

These two stratifications include unadulterated discovery learning, in which students are given minimal input via an instructor, and guided discovery learning in which pedagogues do not provide answers, but provide all of the cognitive tools and methods required for students to find the answers on their own. As previously denoted, the latter form of discovery-based learning was supported by statistical evidence in "Does discovery-based instruction enhance learning" as being of greater use to students than unstructured discovery-based learning.

There is a plethora of research corroborated by empirical evidence that suggests that guided discovery-based learning is one of the preferred methods of pedagogy, for the simple fact that it incorporates the best practices of traditional instruction-based learning and of the constructionist tendencies of discovery-based instruction. Ali Gunay Balim's journal article, "The effects of discovery learning on students' success and inquiry learning skills" provides empirical evidence that attest to the virtue of guided discovery learning.

The research performed in this article divided 57 seventh graders into science classes in which one group was taught using guided discovery learning techniques and the other was taught using conventional methods for instruction. The primary basis for the data was the usage of a pretest and a post-test; each group took the pretest without having any exposure to guided discovery learning. During the posttest, the control group still had no experience with this method of instruction, whereas the other group had four weeks' worth of this type of instruction.

The statistical data overwhelmingly supported the virtues of guided discovery-based instruction. With a t-value of 9.76, the experimental group -- taught using discovery instruction that was guided -- consistently performed higher at a median score of 14.84, versus that of the control which had a median score of 9.95. Accordingly, there was a "significant difference between the control and the experimental groups and the activities, which are prepared consistently with the discovery learning method, and have positive effects upon the success of students" (Balim, 2009, p. 9).

It is fairly noteworthy to point out what exactly it is about guided discovery-based instruction that renders it more beneficial than unstructured discovery learning, and which is alluded to in the statistical evidence that places conventional instruction-based learning as more beneficial than unstructured discovery-based learning in the first of the two meta-analyses in the article by Alfieri et al.

Due to the level of autonomy that students have during unstructured discovery learning, there is a higher likelihood of students erroneously reaching conclusions due to methods which are not supported by solid facts (Alfieri et al., 2011). The boon of this pedagogical methodology is that students are allowed to feel some of the joy of discovery. However, there is also a very real possibility that students may experience other feelings related to wrong answers or lack of progress including confusion, frustration, or what may be even worse -- reaching incorrect answers.

Moreover, the very basis of discovery learning is intrinsically rooted within conventional instruction or within guided discovery learning. Even in unstructured discovery-based learning, teachers give students some form of an example which they are usually told to discover the principles of themselves. Without any instruction whatsoever, students would not have a place to begin. This concept is.
