This paper demonstrated how to apply Machine Learning (ML) techniques to analyze student interaction data collected in an online mathematics game. Using a data-driven approach, we examined 1) how different ML algorithms influenced the precision of middle-school students' (N = 359) performance (i.e. posttest math knowledge scores) prediction and 2)…

This paper demonstrates how to apply Machine Learning (ML) techniques to analyze student interaction data collected in an online mathematics game. We examined: (1) how different ML algorithms influenced the precision of middle-school students' (N = 359) performance prediction; and (2) what types of in-game features were associated with student…

In this article, I analyze teachers' use of students' everyday knowledge and experiences as resources for learning in educational dialogues. By analyzing video data of teachers' attempts to contextualize instruction in naturalistic settings in a lower secondary school, I examine how teachers use such resources to support and guide student…

Regarding constructivism as a learning philosophy and/or a model of knowing, a person (learner or mentor) based on her/his preconceptions and on personal knowings could actively participate in an interaction with another person (learner or mentor) in order to construct her/his personal knowledge. In this research I will analyse "meaning…

This paper describes how early childhood teachers' incorporation of pauses raises the quality of talk-in-interaction during play-based mathematics activities. Responses of both children and teachers are shown to be more contingent and expansive when conversations include protracted pauses than during interactions in which pauses are largely…

Changing practices in schools is a very complex endeavor. This paper is about new practices we prompted to foster collaboration and critical reasoning in science classrooms: the presentation of pictures representing different perspectives, small group synchronous argumentation, and moderation of synchronous argumentation. A CSCL tool helped in…

Tutorial dialogues can be analyzed as an interaction in which a tutor "debugs" a student's knowledge representation by diagnosing and correcting conceptual misunderstandings. Some tentative steps toward a theory which describes tutorial interactions are outlined. The goal structure of a tutor, types of conceptual bugs that students have…

A total of 100 second graders were pretested for conservation of length and weight. Fifty pairs were then formed, each pair consisting of one conserver and one nonconserver. During the second session, the children attempted to resolve their opposed answers on the conservation tasks and on two control questions as well. On both length and weight,…

Statistical interactions between two instructional methods and five cognitive aptitudes were examined to determine whether the methods are most effective among different learners. Sixth grade students (n=275) were randomly assigned to eight periods of rule-example (ruleg) or example-rule (egrule) programmed instruction in critical thinking.…

Reports the results of an investigation into factors associated with variations in students' ability to achieve conceptual learning gains in a physics course that employs interactive-engagement methods. Explores the correlation between students' normalized learning gains and their initial level of physics concept knowledge, pre-instruction…

A study was conducted on the relationships between information seeking and individual cognitive structures (both individual cognitive complexity and the constructs used to understand others). Specifically, the study sought to determine how people use questions to reduce the uncertainty of meeting new people in impression-formation interviews. The…

Three related studies clarify and extend the meaning of interaction involvement: (1) examines the factor structure of the Interaction Involvement Scale; (2) reports a correlation of analysis of newly interpreted involvement factors, including neuroticism, extraversion, communication competence, etc.; and (3) reports initial findings of the…

To investigate whether problem-based learning leads to conceptual change, the cognitive and metacognitive processes of a group of medical students were studied during the problem analysis phase, and their verbal communication and thinking processes were analyzed. Stimulated recall of the thinking process during the discussion detected a conceptual…

This study investigated the flexibility of 16 supervisors in implementing a developmental approach to supervisor-supervisee interaction during the postobservation conference. Specific objectives included determining: (1) if supervisors' diagnoses of supervisees' conceptual levels (CL) agreed with the Paragraph Completion Method (PCM) measurement…
