Using a computer simulation to teach attitude surveying

An interactive computer program that simulates, for teaching purposes, the procedures involved in carrying out an attitude survey is described. Students make decisions about the content and length of an attitude questionnaire, as well as about the procedures to be used to sample the population. Students’ inferences about the population characteristics can be compared with the actual characteristics (predetermined by the instructor) to provide students with an indication of the merits of the alternatives they chose.     

How to teach a pigeon to maximize overall reinforcement rate

In two experiments deviations from matching earned higher overall reinforcement rates than did matching. In Experiment 1 response proportions were calculated over a 360-response moving average, updated with each response. Response proportions that differed from the nominal reinforcement proportions, by a criterion that was gradually increased, were eligible for reinforcement. Response proportions that did not differ from matching were not eligible for reinforcement. When the deviation requirement was relatively small, the contingency proved to be effective. However, there was a limit as to how far response proportions could be pushed from matching. Consequently, when the deviation requirement was large, overall reinforcement rate decreased and pecking was eventually extinguished. In Experiment 2 a discriminative stimulus was added to the procedure. The houselight was correlated with the relationship between response proportions and the nominal (programmed) reinforcement proportions. When the difference between response and reinforcement proportions met the deviation requirement, the light was white and responses were eligible for reinforcement. When the difference between response and reinforcement proportions failed to exceed the deviation requirement, the light was blue and responses were not eligible for reinforcement. With the addition of the light, it proved to be possible to shape deviations from matching without any apparent limit. Thus, in Experiment 2 overall reinforcement rate predicted choice proportions and relative reinforcement rate did not. In contrast, in previous experiments on the relationship between matching and overall reinforcement maximization, relative reinforcement rate was usually the better predictor of responding. The results show that whether overall or relative reinforcement rate better predicts choice proportions may in part be determined by stimulus conditions.     

Using a personal robot to teach young children.

Seventy-five preschool children were instructed about birds by a human teacher, a moving personal robot, a stationary personal robot, and a tape recorder. How much the children learned and how much attention the children paid were compared for each type of instruction. The children learned when they were taught by the human teacher and when they were taught by the animated and the stationary robots. The children paid more attention to the live teacher and to the moving robot than they did to the stationary robot or to the tape recorder. The difference between the amount of attention the children paid to the animated robot and the amount of attention they paid to the human teacher was not statistically significant.     

Using a combined blocking procedure to teach color discrimination to a child with autism

A combined blocking procedure was used to teach a child with autism to select two colors on request. First, two color cards were placed at fixed locations on a table and the experimenter repeatedly requested the child to touch one of the colors. After 10 consecutive correct selections, the child was asked to touch the other color. Blocks of trials with each color were systematically thinned until requests were presented randomly with few errors. Subsequently, the location of the selection cards was systematically alternated until the child was able to touch the correct card when both requests and card positions were presented in random fashion.     

Interactive computer training to teach discrete‐trial instruction to undergraduates and special educators in Brazil: A replication and extension

Discrete‐trial instruction (DTI) is a behavioral method of teaching young children with autism spectrum disorders (ASD) that has received a significant amount of research support. Because of a lack of qualified trainers in many areas of the world, researchers have recently begun to investigate alternative methods of training professionals to implement behavioral teaching procedures. One promising training method is interactive computer training, in which slides with recorded narration, video modeling, and embedded evaluation of content knowledge are used to teach a skill. In the present study, the effectiveness of interactive computer training developed by Pollard, Higbee, Akers, and Brodhead (2014), translated into Brazilian Portuguese, was evaluated with 4 university students (Study 1) and 4 special education teachers (Study 2). We evaluated the effectiveness of training on DTI skills during role‐plays with research assistants (Study 1) and during DTI sessions with young children with ASD (Studies 1 and 2) using a multiple baseline design. All participants acquired DTI skills after interactive computer training, although 5 of 8 participants required some form of feedback to reach proficiency. Responding generalized to untaught teaching programs for all participants. We evaluated maintenance with the teachers in Study 2, and DTI skills were maintained with 3 of 4 participants.     

Using computers to teach behavior analysis

When it is impractical to provide behavior analysis students with extensive laboratory experience using real organisms, computers can provide effective demonstrations, simulations, and experiments. Furthermore, such computer programs can establish contingency-shaped behavior even in lecture classes, which usually are limited to establishing rule-governed behavior. We describe the development of computerized shaping simulations and the development of software that teaches students to discriminate among reinforcement schedules on the basis of cumulative records.     

An instructional package to teach communication behaviors in a classroom setting

An instructional package consisting of modeling, written and behavioral rehearsal, and feedback was used to teach communication behaviors (simple sentence responses, information responses, and eye contact) to 17 emotionally handicapped students, ages ranging between 11 and 17 years. A multiple baseline analysis indicated that the communication behaviors targeted for training increased significantly following implementation of the instructional package. These behaviors also generalized across settings and nontrained questions and were maintained across time. Finally, the average amount of training time required for each subject was 2 hours, indicating that the use of the instructional package in a classroom setting was economical. These results show that communication behaviors can be delivered effectively and economically in a classroom setting.     

Using computer conferencing to formulate a computer simulation of transitive behavior

The activities of a group engaged in simulation modeling via computer conferencing are described, and the model which resulted from those activities is briefly outlined. The phenomena which were modeled were initially described in a series of studies by Trabasso and his colleagues. These studies centered upon exhibition of transitive choices by children and adults, and supported the hypothesis that the choices were guided by formation of “linear arrays“ of the choice objects.     

How to check a computer program

The usual ways of checking computer programs have important flaws. A better way to check a program you have written is to have someone else write a program that does the same thing and then compare the output of the two programs over a wide range of input. Two examples are described.     

Using artificial life to teach evolutionary biology

This paper presents a pilot study on the use of artificial life software in an educational setting. Two groups of high school students received a standard lesson in evolutionary biology followed by a software session. The experimental group used the suite of artificial life software presented in this paper; the control group used a commercial multimedia hypertext. At the end of the software session both groups were asked to fill in a simple multiple-choice questionnaire testing the students knowledge of various aspects of evolutionary biology. The results show that the group using the artificial life software performed significantly better than the control group. We argue that the experimental group may learn more effectively because the artificial life makes it possible for students to perform experiments, a possibility not available to the control group.

Using multiple-exemplar training to teach a generalized repertoire of sharing to children with autism

The current study examined the utility of multiple-exemplar training to teach children with autism to share. Stimuli from 3 of 4 categories were trained using a treatment package of video modeling, prompting, and reinforcement. Offers to share increased for all 3 children following the introduction of treatment, with evidence of skill maintenance. In addition, within-stimulus-category generalization of sharing was evident for all participants, although only 1 participant demonstrated across-category generalization of sharing. Offers to share occurred in a novel setting, with familiar and novel stimuli, and in the presence of novel adults and peers for all participants during posttreatment probes.     

A taxonomy of approaches to teach spelling

This paper presents a comprehensive taxonomy for classifying major approaches to teach spelling. The Traditional Approach is based on linguistic theory, and is predicated on the assumption that there is regularity to the spelling of words in the English language. Many commercially-based spelling programs use the Traditional Approach. The Remedial Approach can be divided into four subcategories, two of which employ multisensory methods. Horn's remedial method combines elements of visualization, pronunciation, and spelling recall, whereas the phonovisual method is phonetically based, and stresses visual and auditory discrimination of letter sounds. Methods under the Specialized Approach can be considered discrete spelling interventions based on applied behavior analysis, direct instruction, spelling rules, cognitive behavior modification, peer tutoring, or computer applications. The authors' position is that the Specialized Approach offers the optimum combination of instructional efficiency and effectiveness consistent with the concept of the least restrictive alternative. We believe that self-correction is the best exemplar of this approach.     

Using stimulus equivalence technology to teach statistical inference in a group setting

Computerized lessons employing stimulus equivalence technology, used previously under laboratory conditions to teach inferential statistics concepts to college students, were employed in a group setting for the first time. Students showed the same directly taught and emergent learning gains as in laboratory studies. A brief paper-and-pencil examination, suitable for classroom use, captured effects demonstrated previously through laboratory tests. The results support the extension of the lessons to more naturalistic settings.     

Using a modified constant prompt-delay procedure to teach spelling to students with physical disabilities

Current research suggests that constant delay is an effective means of teaching students through near-errorless learning. The current study examined how procedures used in previous research may be modified so that constant delay can be implemented with students who have physical disabilities that prevent them from engaging in fluent academic responding. A multiple baseline design with probes was used to assess the effectiveness of a modified constant-delay procedure in teaching spelling to students with physical disabilities. This procedure was found to be effective for all 3 students.     

Comparing mand training and other instructional methods to teach a foreign language

The purpose of the current study was to examine the effects of mand, tact, and native‐to‐foreign (NFI) and foreign‐to‐native (FNI) intraverbal training on the acquisition of a foreign language. We used a multiple‐baseline design across participants with an embedded adapted alternating treatments design to compare the effects of mand training, tact training, NFI training, and FNI training on the acquisition rate of Chinese words in four typically developing adults. We also examined the emergence of untrained foreign language responses for each training condition. Data for 3 out of the 4 participants suggest that mand training was the most efficient training procedure with respect to acquisition rate. The greatest amount of emergent responding was observed for the mand and tact training conditions.     

Using equivalence-based instruction to teach piano skills to children

The purpose of the current study was to evaluate the effects of equivalence-based instruction (EBI) on learning to play individual notes and simple songs on the piano. Participants were 4 typically developing children and 4 children with a diagnosis of autism spectrum disorder (ASD). They were exposed to a series of auditory–visual matching-to-sample procedures using musical stimuli. Following training, participants were tested on the emergence of novel untrained relations and generalization in the form of playing two songs on a keyboard. Results suggest that the EBI was effective in teaching piano playing skills with both typically developing children and children with ASD. The success of this procedure is indicative of the wide-ranging applications of EBI to novel and creative domains.
