Purposive Learning01:22

Purposive Learning

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a bonus...
Problem-Solving01:29

Problem-Solving

Effective problem-solving consists of two steps: 1. identifying the problem and 2. selecting the appropriate problem-solving strategy (i.e., a plan of action used to find a solution). Humans use four problem-solving strategies:
Cognitive Learning01:21

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...
Machines: Problem Solving I01:22

Machines: Problem Solving I

A toggle clamp is a mechanical device commonly used for holding and clamping objects in various applications, such as woodworking, metalworking, and assembly operations. Consider a toggle clamp subjected to a force of 200 N at the handle. The vertical clamping force can be calculated, provided the dimensions of the toggle clamp are known.
The toggle clamp system is a machine structure consisting of movable, pin-connected multi-force members that form a stabilized system to transmit forces. The...
Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...

Area of Science:

  • Medical Education
  • Linguistics
  • Cognitive Science

Background:

  • Problem-based learning (PBL) is widely researched, but its internal discourse processes are less understood.
  • Key differences in PBL include extensive student talk (3-5 hours/week), with limited analysis of vocabulary and cognitive processes during discussions.
  • Previous research has not deeply explored the linguistic and cognitive mechanisms underlying PBL's effectiveness.

Purpose of the Study:

  • To analyze the linguistic and cognitive processes within problem-based learning (PBL) discussions.
  • To quantify the use of technical vocabulary and identify reasoning, questioning, and explaining episodes in PBL.
  • To explore the utility of corpus analysis for understanding student discourse in medical education.

Main Methods:

  • Professionally transcribed recordings of a PBL case involving a facilitator and seven students across three sessions.
  • Utilized Wmatrix2 software for corpus linguistic analysis of the transcribed text.
  • Quantified inter-sessional use of technical vocabulary, reasoning, questioning, and explaining episodes.

Main Results:

  • Compared the frequency of technical words and discourse episodes (reasoning, explaining, questioning) across PBL sessions.
  • Related linguistic variations to the specific focus of each session.
  • Generated concordances to identify and monitor instances of questioning, explaining, and reasoning within the discourse.

Conclusions:

  • Corpus analysis is a valuable tool for analyzing PBL transcriptions in medical education.
  • This methodology can monitor the development of technical vocabulary and scientific/clinical reasoning skills.
  • Proposes corpus analysis as a powerful approach to explore cognitive and linguistic developments in PBL discourse.
