Problem statement:The purpose of this study was to determine the effect of cooperative learning on mathematics achievement and attitude towards mathematics. Approach: This quasiexperimental study was carried out on two form one classes in Miri, Sarawak. One class (n = 44) was assigned as an experimental group and the other (n = 38) was assigned as a control group. The two groups were pre-tested prior the implementation. At the end of the study, post test was given, while daily quiz was used as a tool for formative testing. Teaching and learning process was carried out for two weeks. Data were analyzed using the t-test to determine performance by comparing the mean of the post test for treatment and control group. Results: The results of this study showed that cooperative learning methods improve students' achievement in mathematics and attitude towards mathematics. Conclusion:The researchers concluded that cooperative learning is an effective approach, which mathematics teachers need to incorporate in their teaching.

Objective  To investigate the effect of location of the testis on both testicular development and fertility in unilateral cryptorchidism. Material and methods  Forty‐nine Wistar King A newborn male rats were divided into three groups. In group 1 (15 rats) intra‐abdominal unilateral cryptorchidism were created by the intra‐abdominal fixation of the testis in the neonatal period. In group 2 (16 rats) extra‐abdominal unilateral cryptorchidism was created by extra‐abdominal fixation of the gubernaculum in the neonatal period. In group 3, 18 rats underwent a sham operation as controls. At 90 days of age, fertility was then assessed in each rat by housing it with two mature virgin females for 2 weeks. Thereafter, at 115–120 days of age, the rats were killed and their testes removed for histological examination. Results  There was no significant difference in the pregnancy rate between females coupled with rats from any group, but the mean number of offspring was significantly lower in females coupled with rats in group 1 than in group 2. Furthermore, histological examination of both the cryptorchid and contralateral scrotal testes showed more severe changes in the intra‐abdominal than the extra‐abdominal testes. Conclusion  These results suggest that intra‐abdominal cryptorchid testes are significantly more impaired than extra‐abdominal cryptorchid testes, and that such impairment might be caused by exposure of the testis to a higher temperature. The more severely impaired undescended testes may thus induce the degeneration of the contralateral scrotal testis and thereby cause subfertility in the intra‐abdominal unilateral cryptorchid rat model.
