• Energy is a Core disciplinary idea of Next Generation Science Standards (NGSS Lead States, 2013)
• Research on students’ conceptions about heat have revealed that everyday experiences prevail over scientific explanations (across age groups) (Erickson, 1979; Kesidou & Duit, 1993; Schnittka & Bell, 2009)
• Heat is hot or warm
• Heat is a “mysterious entity with the essential property of hotness that can propagate through” (Wiser & Amin, 2001, p. 335)
• Temperature is a degree of hotness
WHY HEAT?

CONCEPTUAL FRAMEWORK
An imagistic mental model in which the student visualizes the interactions of unobservable elements such as molecules to explain why observable phenomena happen (Ahn, Kalish, Medi, & Gelman, 1995; Brown, 1993; Cheng & Brown, 2015)

CONCEPTUAL FRAMEWORK
Movement of the arms and hands closely synchronized with the flow of speech(McNiel, 1992)
Gestures are evidence that knowledge itself is embodied (Alibali & Nathan, 2012; Goldin-Meadow, 2011; Roth, 2001)

CONCEPTUAL FRAMEWORK
Computer generated, dynamic model of the real world and its processes (Smetana & Bell, 2012)
Simulations are flexible, adaptable and simplistically represent complex and abstract phenomena (Hilton &
Honey, 2011; Smetana & Bell, 2012)

FINDINGS
While coding the interviews, a consistent set of explanatory ideas emerged
1. Steam heats the handle of the spoon2. Metal is a good conductor3. Heat is an entity that goes through the spoon4. Heat moves like a wave through the molecules of the spoon5. Heat is caused by friction between molecules
Some students verbally stated these ideas, but in many cases, attending to gestures provided further insight into these conceptions

FINDINGS

FINDINGS
Other interactions with explanation:
When we noticed student’s using gestures while explaining, we asked them to use their hands while they explained

FINDINGS
• Andrew’s growth in understanding is made visible through his representational gestures
• Explicit requests to “show” gestures reveal nuances of understanding not mentioned before
• Drawing attention to conceptually-grounded gestures may make them more salient to the learner

IMPLICATIONS
• Representational gestures can reveal deeper conceptual ideas• Attending to gestures (as teacher and learner) can make abstract
interactions more salient to the learner.• Simulations taking gestural feedback may be a helpful resource for
developing mechanistic explanations in science.
