Conversational agents have been widely used in education to support student learning. There have been recent attempts to design and use conversational agents to conduct assessments (i.e., conversation-based assessments: CBA). In this study, we developed CBA with constructed and selected-response tests using Rasa--an artificial intelligence-based…

The focus of biology education has shifted from memorization to conceptual understanding of core biological concepts such as matter and energy relationships. To examine undergraduate learning about matter and energy, we incorporated constructed-response (CR) questions into an interactive computer-based tutorial. The objective of this tutorial is…

In this paper we report the results of an experiment designed to test the hypothesis that when faced with a question involving the inverse direction of a reversible mathematical process, students solve a multiple-choice version by verifying the answers presented to them by the direct method, not by undertaking the actual inverse calculation.…

Automated writing evaluation (AWE) systems can provide immediate computer-generated quantitative assessments and qualitative diagnostic feedback on an enormous number of submitted essays. However, limited research attention has been paid to locally designed AWE systems used in English as a foreign language (EFL) classroom contexts. This study…

Recent studies show that a new strategy called differential-associative processing is effective for learning related concepts; however, our knowledge about differential-associative processing is still limited. Therefore the goals of the present study are to assess the duration of knowledge that is acquired from using differential-associative…

Educational researchers have "rarely" addressed the problem of how to provide feedback on constructed responses. All participants (N = 76) read a story and completed short-answer questions based on the text, with some receiving feedback consisting of the exact material on which the questions were based. During feedback, two groups receiving…

Research with 38 undergraduates studied a technique for assessing conformity on a ratio scale and variables used to analyze normative and information factors. Computer presentation of the statistics and storage of responses allows assessment of discrepancies between actual line length and length of the reproductions made with/without peer…

Two experiments reproduced in a simulated computerized test-taking situation the effect of two of the main determinants in answering an item in a test: the difficulty of the item and the time available to answer it. A model is proposed for the time to respond or abandon an item and for the probability of abandoning it or answering it correctly. In…

In a counterbalanced, within subjects, repeated measures design, 130 undergraduates were administered the Computer-Assisted Hypnosis Scale (CAHS) and the Stanford Hypnotic Susceptibility Scale and were hypnotized. The CAHS was shown to be a psychometrically sound instrument for measuring hypnotic ability. (SLD)
