Bayesian Knowledge Tracing (BKT) is a commonly used approach for student modeling, and Long Short Term Memory (LSTM) is a versatile model that can be applied to a wide range of tasks, such as language translation. In this work, we directly compared three models: BKT, its variant Intervention-BKT (IBKT), and LSTM, on two types of student modeling…

Cognitive load theory (CLT) (Sweller 1988, 1998, 2010) provides us a guiding framework for designing instructional materials. CLT differentiates three subtypes of cognitive load: intrinsic, extraneous, and germane cognitive load. The three cognitive loads are theorized based on the number of simultaneously processed elements in working memory.…

Abstraction is one of the methods for learning knowledge with using mental processes that cannot be obtained through experiment and observation. RBC model that is based on abstraction in the process of creating knowledge is directly related to mental processes. In this study, the RBC model is used for the high school students' processes of…

Student understanding of the equilibrium coexistence of a liquid and its vapor was the subject of an extended investigation. Written assessment questions were administered to undergraduates enrolled in introductory physics and chemistry courses. Responses have been analyzed to document conceptual and reasoning difficulties in sufficient detail to…

Cognitive science principles should have implications for the design of effective learning environments. The self-explanation principle was chosen for the current work because it has developed significantly over the last 20 years. Early formulations hypothesized that self-explanation facilitated inference generation to supply missing information…

This study first used a new approach, combining students' ontological beliefs and process explanations, to represent students' mental models of heat conduction and then examined the relationships between their mental models and their predictions. Clinical interviews were conducted to probe 30 undergraduate physics students' mental models and their…

Making assumptions is an important step in solving many real-world problems. This study investigated whether participants who could solve well-defined physics problems could also solve a real-world physics problem that involved the need to make assumptions. The participants, who all had at least a BA in physics, were videotaped "thinking aloud"…

Discusses the results of a study that explored first year university students' ideas about measurement in the physics laboratory. Uses the 'point' and 'set' paradigms as a model to analyze responses to written probes. (Contains 21 references.) (DDR)

Presents the epistemology of scientific concepts from a schematic modeling perspective. Discusses students' initial cognitive states based on the level of commensurability between students' own concepts and their scientific counterparts. Contains 87 references. (DDR)

Examines third year university physics students' use of models when explaining familiar phenomena involving interaction between metals and electromagnetic radiation. Concludes that few students use a single model consistently. (Contains 27 references.) (DDR)

Reports on research designed to discover whether certain conceptual difficulties experienced by present day students in the realm of action at a distance are parallel to the experiences of scientists in previous generations. Contains 60 references. (DDR)

Explores high school students' collaborative efforts in solving qualitative physics problems and investigates how and whether confronting students with varying views improves problem solving skills. (Contains 22 references.) (DDR)

Results of a case study (one graduate physics tutor) demonstrate that a person's conceptions, which include metaphysical commitments, play a significant role in the way s/he understands complex subject matter such as Einstein's Special Theory of Relativity. (Author/SK)

Presents a series of standard demonstrations as examples of activities that can be used to introduce multiple concepts and tie different sections of an introductory physics course together. Contributes to changes in classroom dynamics by stimulating student engagement and encouraging inclusivity. (Contains 23 references.) (DDR)

Identifies middle school and college students' prior ideas about electrostatic induction. Presented students with observational evidence that supported or refuted their own prior ideas in an interview format. Concludes that the Lakatosian rather than the Popperian view is more acceptable in understanding students' responses to conflicting…
