Learning Based Technology in Education : Learning Based Technology in Education PRED 213- Educational Technology 1 Overview of Computer Based Education : Overview of Computer Based Education Computer Based Instruction (CBI) The broadest terms and can refer to virtually any kind of computer use in educational settings, including drill-and-practice, tutorials, simulations, instructional management, supplementary exercises, programming, database development, writing using word processors, and other applications. Overview of Computer Based Education : Overview of Computer Based Education Computer Managed Instruction (CMI) It can refer either to use of computers by school staff to organize school data and make instructional decisions or to activities in which the computer evaluates students’ test performance, guides them to appropriate instructional resources, and keeps records of their progress. Overview of Computer Based Education : Overview of Computer Based Education Computer Enriched Instruction (CEI) It is defined as learning activities in which computers Generate data as students’ request to illustrate relationships in models of social or physical reality. Execute programs developed by the students. Provide general enrichment in relatively unstructured exercises designed to stimulate and motivates students. Overview of Computer Based Education : Overview of Computer Based Education Computer Assisted Instruction (CAI) It is a narrower term and most often refers to drill-and-practice, tutorial or simulation activities offered either by themselves or as supplements to traditional, teacher directed instruction. It refers to instruction or remediation presented on a computer. It involves using the computer in a classroom teaching role. It is a software that includes tests and activities for individualized instruction and the performance of the students are programmed by the system. Also called educational software. Concepts of Computer Assisted Instruction (CAI) : Concepts of Computer Assisted Instruction (CAI) Characteristics of CAI Types of CAI Software Advantages and Disadvantages Characteristics of CAI : Characteristics of CAI It has the capacity to initiate flexible interactions with the student which is not possible in the teaching machines. The computer is able to record and store all the responses of the students. It can use the information in deciding what information to give the student next. It can branch not just in terms of one answer but also in terms of a whole series of previous answers. It can also record the time taken to answer a question and the degree of correctness of the student’s response. It uses information in planning to determine which branch to take. Types of CAI Software : Types of CAI Software Drill and Practice Software Tutorial Software Simulation Software Information Software Drill-and-Practice Software : Drill-and-Practice Software Drill and practice software is one of the earliest types of educational software, and many educators today believe it to have little value in the classroom, referring to it as "drill and kill" because it can lead to boredom through repetition. However, drill and practice software does have some benefits. It provides the student with individualized practice; the student must answer every question. Purpose of Drill-and-Practice Software : Purpose of Drill-and-Practice Software The purpose of drill and practice software is to have the learner memorize information. It does not act as the teacher, but as a kind of automated flash card. The program presents a question to the learner, the learner responds, and the software then gives feedback as to whether the answer is correct or incorrect. Most drill and practice software will accept two incorrect answers, and then provide the correct answer so that the learner is not stuck on a particular item for a long period of time. Purpose of Drill-and-Practice Software : Purpose of Drill-and-Practice Software Assists students in reviewing, rehearsing, reinforcing, and practicing concepts to which they have already been introduced. It does not introduce new concepts Provides immediate and relevant feedback to students. It prevents students from learning something incorrectly. Can focus on concepts, problems, etc. that a student needs to work on. It does not force students to go over topics that they already know. Can identify mastery. Mastery is often indicated when students can complete ten problems in a row without making any mistakes Tutorial Software : Tutorial Software Unlike Drill and Practice software, Tutorial software is intended to introduce new concepts. It does not emphasize practice or reinforcement, but focuses on the presentation of new material in a format that captures the attention of a student, and keeps him/her focused on the most important aspects of the new topics. Constant or periodic interaction with the student may be provided to prevent the student’s attention from wandering and to evaluate his/her grasp of the new material. Tutorial Software : Tutorial Software Tutorial software has value to the learner in that it allows the learner to answer every question, proceed at her/his own pace, and provides privacy of feedback. If the tutorial is branching rather than linear, it is more useful educationally. Linear tutorials allow the learner to take only one path, following it from beginning to end. Branching tutorials, on the other hand, allow the learner to decide which part of the software to use at a particular time. This means that if a student already knows some of the material, s/he can proceed to new, unfamiliar material. Purpose of Tutorial Software : Purpose of Tutorial Software The purpose of tutorial software is to instruct the learner. This type of software may include some practice, but it is primarily used in a teaching capacity. Tutorial software usually assesses the learner's skill, then presents new instruction, gives practice, asks a question and, depending on the learner's response, either remediate by re-teaching, or moves on to the next level. Presents new topics or concepts to students, usually in an entertaining, multimedia format. Purpose of Tutorial Software : Purpose of Tutorial Software Can stimulate student interaction with the new material by providing problems, games, and interactive graphics that focus on the new topics. Can provide short quizzes at critical points so that students know whether or not they are grasping the material. Can provide alternative presentations for students with different learning styles. Simulation Software : Simulation Software Simulation software provides learners with an opportunity to work cooperatively, solve problems, and speculate "what if". This type of software is time effective, cost effective, and safer than experiencing the situation first hand. These are condensed learning exercises specifically designed to represent vital real-life activities by providing learners with the essence or essential elements of the real situation without its hazards, cost or time constraints. Purpose of Simulation Software : Purpose of Simulation Software The purpose of simulation software is to provide approximate computer representations of real-world phenomena or situations. If a simulation program is designed correctly, students who use it may have experiences roughly equivalent to what they might encounter in similar real-world situations. For example, they might be able to study causality by investigating alternate chains of events, or to make choices and explore consequences of their decisions. Reasons to Use Simulations : Reasons to Use Simulations The real-world phenomenon may operate in a time frame that is too long to investigate in the classroom. The real-world phenomenon may be too expensive to simulate in the classroom. Effective simulations can allow the students to gain important insights from the experiments without the expense of actually conducting them. The real world phenomenon may occur only at locations that are remote from the classroom. The students may need to be involved in a role-playing environment that would be impossible for them to realize in the real world at their age. Many real-world situations are simply too dangerous to undertake in the classroom. Types of Simulation : Types of Simulation Procedural simulations These types of simulations are used to give training to students in very specific areas. Situational simulations These types of simulations are often associated with role-playing and exploring consequences of generalized decisions. Physical simulations These types are often associated with science or mathematics. They allow students to conduct experiments and investigate the results, to extract general principles from individual observations or empirical trials, and to quantify and predict results. Special Forms of Simulation : Special Forms of Simulation Discovery Learning Software Problem Solving Softwares Discovery Learning Software : Discovery Learning Software Discovery learning software provides a large database of information specific to a course or content area and challenges the learner to analyze, compare, infer and evaluate based on their explorations of the data. It provides a structured, simulated environment that directs a student's attention toward a topic of interest. It also provides ways for students to manipulate facets of that environment to discover important concepts. Problem-solving Software : Problem-solving Software Problem-solving software is used to aid students in developing high-level problem-solving skills and strategies. In many ways it is like simulation software. Students make decisions by specifying values for variables and then observe the consequences of their decisions. Problem-solving software usually requires a great deal of student input and presents the student with a lot of feedback. Problem-solving Software : Problem-solving Software Some of the skills and strategies that can be fostered by problem-solving software include the following. Classifying things Establishing hierarchies Identifying trends Identifying sequences Breaking a problem into parts Identifying relevant and irrelevant information Working backwards to justify conclusions Eliminating personal biases Making and testing hypotheses Graphing data and interpreting the graphs Using arithmetic and mathematics to calculate or estimate values Information Handling Software : Information Handling Software There is a large amount of software on the market that provides access to convenient and extensive sources of information. Most of this software is packaged on CD-ROMs or DVDs and is organized like an encyclopedia. Unlike written encyclopedias, however, the computer variety includes color images, sound clips, videos, and animations in addition to the text. These features can usually be activated from the text page or from a toolbar menu by clicking on an icon. CD-ROMs and DVDs : CD-ROMs and DVDs CD-ROM encyclopedias are usually organized as individual articles about each of the included topics. Each article can be accessed via a searchable index or from a hierarchical diagram of topics. In addition, hypertext links allow the reader to jump from one article to other related ones. Some information software can automatically access the Internet to search for the latest information on a given topic. Many of the newest offerings are on DVD instead of CD ROM. The much large capacities of DVDs offer huge repositories of information. CD- ROMs and DVDs : CD- ROMs and DVDs The following list shows some examples of CD ROM information sources. Compton's Interactive Encyclopedia Grolier Multimedia Encyclopedia Encyclopedia Britannica World Book Encyclopedia McGraw-Hill Encyclopedia of Science and Technology Moseby's Medical Encyclopedia National Geographic's Picture Atlas of the World Advantages of CAI : Advantages of CAI It helps to determine subsequent activities in the learning situations. The large amount of information stored in the computer is made available to the learner more rapidly than any other medium. The dynamic interaction between the student and instructional programme is not possible to be secured by other medium It can completely individualize materials It can dramatically increase student's access to information. It often engage the interest of students, motivating them to learn and increasing independence and personal responsibility for education Disadvantages of CAI : Disadvantages of CAI Poorly designed CAI systems can dehumanize or regiment the educational experiences and thereby diminish student’s interest and motivation. All individualized instruction and CAI instruct the students in such a way, that all will achieve the same level of competency. Other disadvantages of CAI stem from the difficulty and expense of implementing and maintaining the necessary computer systems. References: : References: Presented By: ED21FA1 Laroco, Sandra R.
