Running head: WHY MINIMALLY GUIDED INSTRUCTION DOES NOT WORK Why Minimal Guidance during Instruction Does Not Work: An Analysis of the Failure of Constructivist, Discovery, Problem-Based, Experiential, and Inquiry-Based Teaching

Evidence for the superiority of guided instruction is explained in the context of our knowledge of human cognitive architecture, expert–novice differences, and cognitive load. Although unguided or minimally guided instructional approaches are very popular and intuitively appealing, the point is made that these approaches ignore both the structures that constitute human cognitive architecture and evidence from empirical studies over the past half-century that consistently indicate that minimally guided instruction is less effective and less efficient than instructional approaches that place a strong emphasis on guidance of the student learning process. The advantage of guidance begins to recede only when learners have sufficiently high prior knowledge to provide "internal" guidance. Recent developments in instructional research and instructional design models that support guidance during instruction are briefly described.

Why Minimal Guidance During Instruction Does Not Work: An Analysis of the Failure of Constructivist, Discovery, Problem-Based, Experiential, and Inquiry-Based Teaching

Cognitive load theory has been designed to provide guidelines intended to assist in the presentation of information in a manner that encourages learner activities that optimize intellectual performance. The theory assumes a limited capacity working memory that includes partially independent subcomponents to deal with auditory/verbal material and visual/2- or 3-dimensional information as well as an effectively unlimited long-term memory, holding schemas that vary in their degree of automation. These structures and functions of human cognitive architecture have been used to design a variety of novel instructional procedures based on the assumption that working memory load should be reduced and schema construction encouraged. This paper reviews the theory and the instructional designs generated by it.

Cognitive Architecture and Instructional Design

Established in 2006, TATA Africa Services (Nigeria) Limited operates as the nodal point for Tata businesses in West Africa. TATA Africa Services (Nigeria) Limited has a strong presence in Nigeria with investments exceeding USD 10 million. The company was established in Lagos, Nigeria as a subsidiary of TATA Africa Holdings (SA) (Pty) Limited, South Africa and serves as the hub of Tata’s operations in Nigeria and the rest of West Africa.

What About Us

Cognitive load theory suggests that effective instructional material facilitates learning by directing cognitive resources toward activities that are relevant to learning rather than toward preliminaries to learning. One example of ineffective instruction occurs if learners unnecessarily are required to mentally integrate disparate sources of mutually referring information such as separate text and diagrams. Such split-source information may generate a heavy cognitive load, because material must be mentally integrated before learning can commence. This article reports findings from six experiments testing the consequences of split-source and integrated information using electrical engineering and biology instructional materials. Experiment 1 was designed to compare conventional instructions with integrated instructions over a period of several months in an industrial training setting. The materials chosen were unintelligible without mental integration. Results favored integrated instructions throughout th...

Cognitive Load Theory and the Format of Instruction

The expertise reversal effect was initially predicted by cognitive load theory as a form of the redundancy effect (see Chapter 11) that occurs when information beneficial to novice learners becomes redundant to those more knowledgeable. It is one of several cognitive load effects that rely on an interaction between a basic cognitive load effect, in this case the redundancy effect, and other factors, in this case levels of expertise. As an example of the expertise reversal effect, detailed textual explanations, especially if they are embedded into diagrams thus reducing the possibility of ignoring them, may be essential for novices but redundant for experts.

The Expertise Reversal Effect

The experiments reported in this article flow from the following assumptions concerning our cognitive processes: (a) Schema acquisition and automation are major learning mechanisms when dealing with higher cognitive activities and are designed to circumvent our limited working memories and emphasize our highly effective long-term memories. (b) A limited working memory makes it difficult to assimilate multiple elements of information simultaneously. (c) Under conditions where multiple elements of information interact, they must be assimilated simultaneously. (d) As a consequence, a heavy cognitive load is imposed when dealing with material that has a high level of element interactivity. (e) High levels of element interactivity and their associated cognitive loads may be caused both by intrinsic nature of the material being learned and by the method of presentation. (f) If the intrinsic element interactivity and consequent cognitive load are low, the extraneous cognitive load is critical when dealing with i...

Why Some Material Is Difficult to Learn

Two experiments investigated alternatives to split-attention instructional designs. It was assumed that because a learner has a limited working memory capacity, any increase in cognitive resources required to process split-attention materials decreases resources available for learning. Using computer-based instructional material consisting of diagrams and text, Experiment 1 attempted to ameliorate split-attention effects by increasing effective working memory size by presenting the text in auditory form. Auditory presentation of text proved superior to visual-only presentation but not when the text was presented in both auditory and visual forms. In that case, the visual form was redundant and imposed a cognitive load that interfered with learning. Experiment 2 ameliorated split-attention effects by using colour coding to reduce cognitive load inducing search for diagrammatic referents in the text. Mental load rating scales provided evidence in both experiments that alternatives to split-attention instructional designs were effective due to reductions in cognitive load.

Managing split-attention and redundancy in multimedia instruction

SUMMARY. Cognitive load theory suggests that many conventional inStructional formats are ineffective as they involve extraneous cognitive activities, which interfere with learning. The split­ attention effect provides one example of the consequences of inappropriate cognitive activities. caused by poor instructional design. Learners are often forced to split their attention between and mentally integrate disparate sources of information (e.g., text and diagrams) before the instruc­ tional material can be rendered intelligible. This preliminary process of mental integration, while :m esse~tial precursor to.l~arning, is likely to impose a heavy extrane,?~s cognitive load. Physical IntegratIOn (e.g., combInIng text and dlagrams) may reduce cognItlve load and so facilitate learning. This study reports findings from two experiments investigating the split-attention effect. Using an engineering programming language (Numerical Control programming), the first experiment investigated the possible advantage of physically integrating text and diagrams. In a normal training environment, the integrated instructions group outperformed the conventional group. Experiment 2 was designed to see if the split-~ttention effect would generalise to an area where mutually referring segments of text are conventIOnally separated, namely, empirical reports in psychology and education. In a laboratory study, Experiment 2 showed that students in an integrated group spent less time processing instructions yet still outperformed students in a conventional group on test questions. The consequences of these results for cognitive load theory and for instruction design are discussed.
