Research Hypotheses
Problem Solving
– Hypothesis 1: Participants who use a navigation map (the treatment group) will
exhibit significantly greater content understanding than participants who do not use
a navigation map (the control group).
– Hypothesis 2: Participants who use a navigation map (the treatment group) will
exhibit greater problem solving strategy retention than participants who do not use
a navigation map (the control group).
– Hypothesis 3: Participants who use a navigation map (the treatment group) will
exhibit greater problem solving strategy transfer than participants who do not use a
navigation map (the control group).
– Hypothesis 4: There will be no significant difference in self-regulation between the
navigation map group (the treatment group) and the control group. However, it is
expected that higher levels of self-regulation will be associated with better
performance.
Motivation
– Hypothesis 5: Participants who use a navigation map (the treatment group) will
exhibit a greater amount of continuing motivation, as indicated by continued
optional game play, than participants who do not use a navigation map (the control
group).

Cognitive Load Theory
• Cognitive Architecture
– Auditory/Verbal and Visual/Spatial Channels/Memory
(Baddeley,1986; Mayer & Moreno, 2003)
– Limited Working Memory (Brunken et al., 2003)
• 7 +/- 2 (Miller, 1956)
• Possibly only 2 or 3 novel elements (Paas et al., 2003)
– Unlimited Long-Term Memory (Mousavi et al., 1995)
• Cognitive Load = mental capacity imposed on working memory
(Sweller & Chandler, 1994)
– Controlled by schema development & Automation
– Intrinsic Cognitive Load: Necessary (Brunken et al., 2003; Paas et al., 2003).
– Germane Cognitive Load: Required to process intrinsic load (Renkl &
Atkinson, 2003).
– Extraneous Cognitive Load: Unnecessary stimuli (Brunken et al. 2003).
• Seductive Details (Mayer et al., 2001; Schraw, 1998).

Scaffolding
(including Graphical Scaffolding)
• Instructional methods
– Should keep cognitive load low (Clark, 2003)
– External methods which replace internal processes (Clark, 2001)
• Scaffolding is an instructional method
• Scaffolding provides support during learning
(Allen, 1997; Chalmers, 2003; van Merrienboer et al., 2002, 2003)
• Graphical Scaffolding
– Includes maps and menus as advance organizers (Jones et al., 1995)
– Maps supported by researchers as visual aids and organizers
(Benbasat & Todd, 1993; Chou & Lin, 1998; Ruddle et al., 1999)
– Should be used for visual tasks (Mayer et al., 2002)

Navigation Maps
• Navigation: Tracking one’s position in an environment to arrive
at a destination (Cutmore et al., 2000)
• Occlusion: when a path is blocked visually (Cutmore et al., 2000)
• Navigation maps effective for occluded 3-D navigation
(Cutmore et al. 2000; Dempsey, 2002)
• Navigation maps effective in 2-D environments with complex
problem solving tasks (Baylor, 2001; Chou & Lin, 1998; Chou et al., 2000)
• Navigation maps effective in 3-D occluded environments with
simple problem solving tasks (Galimberti, 2001)

associated with better performance.
– PARTIALLY SUPPORTED

and problem solving retention improvement
• Control Group: Negative correlation between planning and problem
solving transfer improvement

Discussion
• Reduction of performance for treatment group
offsetting effect of navigation map
– Contiguity Effect (Mayer et al., 1999; Mayer & Moreno, 2003; Mayer & Sims,
1994; Moreno & Mayer, 1999)
• Spatial and temporal
• Results in Split Attention Effect (Atkinson et al., 2000; Mayer, 2001;
Tarmizi & Sweller, 1998)
– Cognitive strain during integration of information
– Extraneous Load (Harp & Mayer, 1998; Mayer, Heiser, & Lonn, 2001; Moreno &
Mayer, 2000; Renkl & Atkinson, 2003; Schraw, 1998)
• Seductive Details (Mayer et al., 2001; Schraw, 1998)
– Affects retention and transfer (Moreno & Mayer, 2000)
• Navigation Map?

Slide 12 of 14
Discussion (cont’d)
• Increase in performance for both groups, offsetting
effect of navigation map
– Strategy Priming
• Ready mind to allow or engage particular relevant schema
(http://filebox.vt.edu/8080/users/dereese2/module8/module08bkup/IDProjectWebpage/lesson4.htm)
• Repetition closely aligned with skill acquisition (Dennis & Schmidt,
2003)
– Lack of priming reduces process of selecting (Moreno & Mayer, 2005)
• Primed during:
– Knowledge map training and SafeCracker training
– During navigation map and basic navigation training
– Start of each game

Implications
• Navigation maps do not guarantee improved
performance
• Further studies are suggested
– Manipulation of contiguity effect
• Integrated versus separated map
– Manipulation of extraneous details
• Low versus high levels of environmental fidelity (both with map use)
• Small versus large environment (both with map use)

Problem Solving Assessment
• Based on O’Neil’s (1999) Problem Solving Model
– Requires content understanding, problem solving strategies, selfregulation
• Transfer questions are alternative to transfer tasks (Moreno & Mayer, 1998)
• Declarative knowledge measured by retention (Day et al., 2001)
• Knowledge map: concepts and links (Schau & Mattern, 1997)
– Reflects the organization of knowledge (Day et al., 2001)
– Reliable and efficient measure of Content Understanding
(Herl et al., 1999; O’Neil, 1999; Ruiz-Primo et al., 1997; Schacter et al., 1999)
Predictive of both retention and transfer (Day et al., 2001)
–
– Reliable measure of Problem Solving Strategies (Baker & Mayer, 1999)
Richard Wainess Dissertation v.4
Presented 12/09/05
Slide 16
Problem Solving Assessment (cont’d)
• Measuring Problem Solving Strategies
– Domain general and specific (Alexander, 1992; Bruning et al., 1999)
– Knowledge Mapping (Baker & Mayer, 1999)
– Problem solving questions
• Positively correlated with retention and transfer (Mayer & Baker, 1998)
• Measuring Self-Regulation
– Includes Metacognition & Self-efficacy (O’Neil, 1999)
• Metacognition: planning & self-checking (Pintrich & DeGroot, 1990)
• Self-efficacy: mental effort and self-efficacy (Zimmerman, 1994, 2000)
– Trait self-regulation questionnaire (Hong & O’Neil, 2001)
• Includes planning, self-checking, mental effort, and self-efficacy
• 32 questions: 8 for each of the four sub-categories

Slide 17
Games and Simulations
• Games: rules, constraints/privileges, imaginative, linear (Gredler, 1996)
• Simulation-Games: combination of games and simulations (Gredler, 1996)
• Motivation in games: fantasy, control & manipulation, challenge & complexity,
curiosity, competition, feedback, fun
• Positive outcomes:
– Numerous knowledge outcomes attributed to games and simulations
• Warning about anecdotal and descriptive evaluations (Leemkuil et al., 2003; Wolfe, 1997)
– Generalizable skills outcomes
(Day et al. 2001; Green & Bavelier, 2003; Greenfield et al., 1994)
• Negative or null outcomes:
– Reviews and meta-analyses cite mixed or negative reviews
(Dekkers & Donatti, 1981; Druckman, 1995)
– Positive attitude toward games doesn’t necessarily equal learning
(Brougere, 1999; Salas et al., 1998; Salomon, 1984)
• Outcomes related to Instructional Design, not games/simulations
(de Jong & van Joolingen, 1998; Garris et al., 2002; Gredler, 1996; Leemkuil et al., 2003; Thiagarajan, 1998)

transfer, trait self-regulation, number of safes opened, and
continuing motivation.
• Mixed Group, Repeated Measures Factorial ANOVA:
Examine effect of use/non-use of navigation map on content
understanding, problem solving strategy retention and transfer,
and number of safes opened.
• Correlations: between self-regulation components (planning,
monitoring, effort, self-efficacy) and content understanding,
problem solving strategy retention and transfer, and number of
safes opened for each group and both groups combined.
