This indicates that our intervention was efficient in helping students arrive at correct answers with relatively low mental effort (Kalyuga & Sweller
CLT research suggests novice examiners require substantial instructional support, time, effort, and deliberate practice before they can construct new schemas to function as expert examiners who are able to administer tests without errors (Kalyuga & Sweller
When it comes to instructional design, with or without the use of technology, educators at every level should carefully consider the ease with which students' working memories and capacity for cognitive load can be overwhelmed (Chandler & Sweller
, 1991; Mayer, 2009).
e Tuovinen & Sweller
, 1999), extraneous cognitive load is reduced by having learners complete small parts of worked-out examples, then progressively complete larger parts of additional worked-out examples until the target task is accomplished.
Oral narration Concurrent with visual Sweller

, van Merrienboer, and Paas (1998, 259) propose that "appropriate instructional designs decrease extraneous cognitive load but increase germane cognitive load.
Fortunately, Ruth Clark, Frank Ngygen, and John Sweller
have come to the rescue with a practical and effective solution in their book Efficiency in Learning: Evidence-Based Guidelines to Manage Cognitive Load.
Compared to textual annotations, audio information avoids a split-attention effect which occurs when switching the attention between two visual information sources (Chandler & Sweller
, 1991; Mayer & Moreno, 2001).
The static nature of the compare problem makes it the most difficult type of addition/subtraction word problem to solve (see Carpenter, Fennema, Franke, Levi, & Empson, 1999; Fuson, Carroll, & Landis, 1996; LeBlanc & Weber-Russell, 1996; Mwangi & Sweller
, 1998; Okamoto, 1996; Pape, 2003; Riley & Greeno, 1988).
Additionally, research suggests that worked examples are more appropriate for inexperienced learners while problem-solving practice is more appropriate for experienced students (Kalyuga, Chandler, Tuovinen, & Sweller
Studies have shown that learning technologies, such as multimedia, can enhance cognitive learning and make students better learners (Baker, 2001; Mayer & Anderson, 1991; Mousavi, Low, & Sweller
, 1995; Moreno & Mayer, 1999).
The causes for such a defect are incompatibility of the solvent sweller
and resin, overaggressive attack by the alkaline permanganate solution, improper resin flow and encapsulation, drilling issues and incomplete resin cure.
For example, instructional materials that use a dual-mode presentation technique--such as auditory text combined with visual diagrams--may result in superior learning and memory performance compared to single-modality formats--such as visual text and visual diagrams (Tindall-Ford, Chandler, & Sweller
, professor, School of Education, University of New South Wales
The need for providing these supports is based on cognitive load theory (Chandler & Sweller
, 1991; Sweller
, 1988), which in its simplest form suggests all learners have limited working memory and learning tasks should be structured so as not to overload it.
