This research was a survey research. Sampling was selected through a progressive random sampling technique with stratification. The research samples were four junior high schools, they are: JHS 4 Makassar, JHS 26 Makassar, JHS 2 Maros, and JHS 4 Sinjai with the total samples were 235 students. Each school was represented by 2 classes. The results of research showed that the students of junior high school who were able to understand the inquiry method that leads to scientific knowledge as much as 17.02%, and ability to organize, analyse, and interpret the quantitative data and scientific information as much as 36.23%. Overall, the conclusion of this study was the scientific literacy of junior high school students in biology teaching was still low. The constructivist learning method should be used by the teacher, such us using inquiry method and completed by an innovative media and learning resources to enhance students' scientific literacy.

Work stealing is an effective load balancing strategy for parallel computing. In this paper, we present dynamic work stealing strategies in a lazy-task creation technique for efficient fine-grain task scheduling. The basic idea is to control load balancing granularity depending on the number of task parents in a stack. The dynamic-length strategy of work stealing uses run-time information, which is information on the load of the victim, to determine the number of tasks that a thief is allowed to steal. We compare it with the bottommost first work stealing strategy used in StackThread/MP, and the fixed-length strategy of work stealing, where a thief requests to steal a fixed number of tasks, as well as other multithreaded frameworks such as Cilk and OpenMP task implementations. The experiments show that the dynamic-length strategy of work stealing performs well in irregular workloads such as in UTS benchmarks, as well as in regular workloads such as Fibonacci, Strassen's matrix multiplication, FFT, and Sparse-LU factorization. The dynamic-length strategy works better than the fixed-length strategy because it is more flexible than the latter; this strategy can avoid load imbalance due to overstealing.
