Improving teachers' content knowledge in mathematics is one way to address the ongoing national concern of poor performance in math. The purpose of this study was to investigate the impact of self-regulated online professional development for teachers' knowledge of fractions, decimals, and percentages, as well as factors prompting that impact.…

In 1968 the New York City Board of Education initiated a large scale test of a computer assisted instruction (CAI) program for drill and practice in elementary arithmetic. The program was a modified version of one developed by Dr. Patrick Suppes of Stanford University. An RCA Spectra 70/45 computer and 192 terminals located in elementary schools…

DISTAR programs were used in learning assistance classes at five Vancouver schools during 1971-72. Those pupils who were taught with the DISTAR Arithmetic program made sizable gains in scores on the Arithmetic subtest of the Metropolitan Achievement Test, but the difference between the gains made by experimental and control groups in arithmetic…

Six classes received problem-centered mathematics instruction for two years in second and third grade. Results indicate that students in these classes scored significantly higher than students in traditional classes on standardized measures of computational proficiency and conceptual understanding.

The efficacy of an early mathematics program aimed at developing number sense and built entirely on children's invented procedures and on their informally acquired quantitative knowledge was studied. To socialize children to think of themselves as reasoners about numbers, the classroom program routinely provided daily conversation about numbers…

The Radio Mathematics Project was established to design, implement, and evaluate a prototype system of teaching elementary mathematics using radio as the major medium of instruction. Daily mathematics lessons were presented to first and second graders in rural and urban primary schools in Nicaragua. Lessons had a radio and a postbroadcast portion,…

The Formative Evaluation and Heuristic Research (FEHR) PRACTICUM, a computerized game, gives practical experience in such program evaluation tasks as problem definition, operationalizing objectives, field study, budgeting, proposal writing, data analysis, and interpretation--without the expense and time commitments required by most research. The…

A review of the possibilities and challenges of computer-assisted instruction (CAI), and a brief history of CAI projects at Stanford serve to give the reader the context of the particular program described and analyzed in this book. The 1965-66 arithmetic drill-and-practice program is described, summarizing the curriculum and project operation. An…

Compared project (n=79) and nonproject (n=111) third-grade students on their conceptual development in arithmetic, their personal goals in mathematics, and their beliefs about reasons for success in mathematics. Project students attained more advanced levels of conceptual understanding and held stronger beliefs about the importance of working…
