This study aims to produce a mathematics enrichment book to facilitate problem-solving ability based on the aspects of validity, practicality, and effectiveness. The research method used is research and development using the ADDIE model which includes the analysis, design, development, implementation, and evaluation stages. The research instruments used consisted of validation sheets, practicality assessment sheets, and test questions for mathematical problem-solving abilities. Validity and practicality data analysis was carried out by converting the total score of quantitative data obtained into five-scale qualitative data. Effectiveness of data analysis is done by determining the percentage of the number of accomplished students and the average test scores of mathematical problem-solving ability. The result of the research is a valid, practical, and effective mathematics enrichment book to facilitate problem-solving ability. The mathematics enrichment book developed has met validity criteria based on the validators’ assessment with the average score in the high category, fulfills the practicality criteria based on the teachers’ assessment with the excellent category, and meets the effective criteria based on the results of the mathematical problem-solving ability with the percentage of students accomplishment of 79.5% and the average score of the test results of 79.

24 students, who participated in a summer session mathematics enrichment program, viewed subliminally presented messages. Prior to each class, the experimental group of 16 viewed a subliminally presented psychoanalytic merging message and the control group of 8 viewed a neutral message. After 20 sessions students were retested. Experimental students had higher mathematics scores than controls. These data are compared with results obtained by other investigators.

Graph or network theory has its traditional applications in such diverse areas as communications, routing and queuing, transportation, environmental network webbing, and PERT (Performance Evaluation and Review Technique) in business and government, It can also be used to trace the spread of information, rumors, and disease in search of an original source. An exercise in the latter was offered to a group of seventh graders taking a mathematics enrichment section in a local community college. It proved both diverse and entertaining.
