tandfonline.com – International comparisons of school-level geoscience education– the UNESCO/IGEO expert opinion survey

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT An international survey of geoscience education has been carried out jointly by UNESCO and the International Geoscience Education Organisation (IGEO) to address the question of ‘How does school-level Earth science education compare across the globe? The survey gathered data from experts in 51 countries, comprising more than half the global population. Most countries (75%) had national standards covering Earth science but these were not followed or are absent in more than half the countries surveyed. Only around 25% of the countries with standardised assessments have Earth science-specific questions. Most teachers of Earth science are non-specialist teachers, whilst support of these teachers through courses and professional development is generally low, with very little financial support provided. Earth science teaching… Continue Reading

Eric.ed.gov – Generalizing Expert Misconception Diagnoses through Common Wrong Answer Embedding

eric.ed.gov har udgivet: Misconceptions have been an important area of study in STEM education towards improving our understanding of learners’ construction of knowledge. The advent of largescale tutoring systems has given rise to an abundance of data in the form of learner question-answer logs in which signatures of misconceptions can be mined. In this work, we explore the extent to which collected expert misconception diagnoses can be generalized to held-out questions to add misconception semantics. We attempt this generalization by way of a question-answer neural embedding trained on chronological sequences of learner answers. As part of our study, we collect natural language misconception diagnoses from math educators for a sampling of student answers to questions within four topics on Khan Academy. Drawing inspiration from machine translation, we use a multinomial… Continue Reading

Eric.ed.gov – Routines in Expert Math Teachers’ Thoughts and Actions.

eric.ed.gov har udgivet: This research was designed to elucidate the activity structures and routines of elementary mathematics teachers by describing what they are, analyzing their frequency and duration, analyzing the functions that routines serve for the cognitive processes of teachers, and beginning to model the chains of routines and their fit with planned or spontaneous actions that make up a lesson. Five “expert” teachers and four novice student teachers, along with their classes, comprised the sample. They were observed over a 3-1/2 month period, with note-taking, videotapes and transcribed interviews providing data. For each teacher, transcribed notes and interviews were analyzed and broken down into action records giving duration, action of student, action of teacher, and a name for the action. For two experts and one novice teacher, a more… Continue Reading

Eric.ed.gov – The Dark Side of CML: A Look at Expert Systems.

eric.ed.gov har udgivet: The paper examines implications of the application of computer expert systems in the field of education, particularly special education. The development of expert systems in general is reviewed as are its applications in education as intelligent tutoring systems and in special education in the areas of student classification, teacher education, math teaching consultancy, and language teaching consultancy. The literature on the role of artificial intelligence is then reviewed noting concerns with increasing reliance on technology, the increasing tendency toward technological elitism, possible reductions in human creativity, and the need for man to control technology and not be controlled by it. While noting the contributions of computer managed learning to special education in individualizing learning and recordkeeping, the paper raises questions concerning effects of future more extensive use… Continue Reading
