Two experiments examined the effects of a multimedia technology referred to as "Time Compressed Animated Delivery" (TCAD), on student learning in a junior-level reproductive physiology course. In experiment 1, participating students received one of two presentations of the same instructional material: TCAD and a lecture captured on video. At the…

An increasing number of K-12 school teachers have been using handheld, or palmtop, computers in the classroom as an integral means of facilitating education due to the flexibility, mobility, interactive learning capability, and comparatively inexpensive cost. This study involved two experiments in handheld computers: (a) a comparison of the…

In this study, we compared a traditional teaching sequence (four distinct lessons) with a block schedule dealing with the ecological adaptations of the water lily. The educational unit contained original plant material and both experimental groups received the same tasks and working sheets. Pupils worked together in groups of three to four pupils…

This paper reports experiment results of teaching large classes of introductory economics with modern learning technology such as MyEconLab or Aplia. This new technology emerges partially in response to the enrollment pressure currently facing many institutions of higher education. Among other things, the technology provides an integrated online…

In this paper the augmentation of worked examples with animations for teaching problem-solving skills in mathematics is advocated as an effective instructional method. First, in a cognitive task analysis different knowledge prerequisites are identified for solving mathematical word problems. Second, it is argued that so called hybrid animations…

Introduction to American Government classes can benefit from the addition of examples from comparative politics. Presenting students with examples of other democratic systems encourages them to confront the costs and benefits of choices made in the American context. Dealing with these "cognitive conflict" tasks facilitates higher level learning on…

This research demonstrates the design of a Joyful Classroom Learning System (JCLS) with flexible, mobile and joyful features. The theoretical foundations of this research include the experiential learning theory, constructivist learning theory and joyful learning. The developed JCLS consists of the robot learning companion (RLC), sensing input…

Analytical competency in classroom situations can be seen as a crucial aspect of teachers' professional competency. While case-based learning is considered to have great potential for teacher education, particularly with respect to the promotion of teachers' analytical skills, there have been very few attempts to investigate the effects of…

We present an inference algorithm for perturbation models based on Poisson regression. The algorithm is designed to handle unclassified input with multiple errors described by independent mal-rules. This knowledge representation provides an intelligent tutoring system with local and global information about a student, such as error classification…

What and how much can children learn without subject teachers? In an attempt to find a limit to self organized learning, we explored the capacity of 10-14 year old Tamil-speaking children in a remote Indian village to learn basic molecular biology, initially on their own with a Hole-in-the-Wall public computer facility, and later with the help of…

The planning of adequate control groups is a central aspect of educational research. Didactical studies, however, are often field studies encountering many problems of everyday classroom teaching? Recent research has indicated that teachers and their beliefs have an enormous influence on learning and retention. Taking this line of evidence…

The effectiveness of four methods of speech instruction with third and fourth grade culturally deprived boys and girls was compared. The methods of instruction varied in regard to the manner in which they were developed and in sophistication from simple instructions on the operation of audiovisual equipment and materials to a commercially…

This dissertation study employed quantitative methods to investigate the impact of adult questioning styles on children's novel vocabulary acquisition during shared storybook reading. In an effort to examine adult qualitative variations in shared storybook readings, two experiments were conducted to assess the effect of noneliciting questions…

In recent years, propensity score matching (PSM) has gained attention as a potential method for estimating the impact of public policy programs in the absence of experimental evaluations. In this study, we evaluate the usefulness of PSM for estimating the impact of a program change in an educational context (Tennessee's Student Teacher Achievement…

HIGH SCHOOL TYPISTS AT FOUR STAGES OF TRAINING PARTICIPATED IN AN INVESTIGATION OF THE RELATIVE EFFECTS OF EXTERNALLY-PACED VERSUS SELF-PACED PRACTICE ON SPEED AND ACCURACY IN ORDINARY TYPEWRITER COPY WORK. TWO TEACHERS IN EACH OF FOUR SCHOOLS TAUGHT BOTH AN EXTERNALLY-PACED AND A SELF-PACED CLASS TO A TOTAL OF 120 STUDENTS PER TREATMENT IN 16…
