Abstract
Science educators define a learning environment in which the problem drives the learning as problem based learning (PBL). Problem based learning can be a learning methodology/process or a curriculum based on its application by the teacher. This paper discusses the basic premise of Problem base learning and successful applications of such learning. PBL enables students to develop skills, and inquiry methodology to solve problems for the future. This important teaching application will better prepare our students to meet a global future. 1. Improve Science Learning with Problem-Based Learning Science educators define a learning environment in which the problem drives the learning as problem based learning (PBL). PBL is used in multiple domains, i.e.: medical education (dentists, nurses, paramedics, radiologists, etc.) and in content domains as diverse as MBA (Bridges, E.M and Hallinger, P., 1996.; Stinson, J. E., & Milter, R. G., 1996.; Kingsland, A.J. 1998), and pre-service teacher education (Hemlo-Silver, 2004). This list is by no means exhaustive, but is illustrative of the multiple contexts in which the PBL instructional approach is utilized (Savery, 2006). The origin of PBL education as it is practice today evolved from an innovative health sciences curriculum created at McMaster University in Canada. The program structures an entire curriculum promoting studentcentered, multidisciplinary education and lifelong learning in professional practices.(Barrows, H.S. and Tamblyn, R.M. 1980; Savery, 2006) In education, this process is adapted and transformed so that the assignment is planned so that the students discover that they need to learn new scientific knowledge to solve the assigned problem. Problems can be assigned from the textbook as extension assignments or student initiated problems. PBL methodology does not require textbooks and encourage students to think out of the ordinary. 2. A Curriculum or Process? The debate on the topic of PBL is a curriculum or process, is dependent on how the teacher uses it in the classroom. If it is the strategy of the teacher is to dedicate, the course to a series of selected and designed problems that demand the learner acquire critical knowledge throughout the course, PBL can be a curriculum and meet the standards set forth by schools and other governing bodies. The Illinois Mathematics and Science Academy (http:// www.imsa.edu/center/) has been providing high school students with a complete PBL curriculum since 1985 and serves thousands of students and teachers as a center for research on problem-based learning. The Problem-based Learning Institute (PBLI) (http://www.pbli. org/) has developed curricular materials (i.e., problems) and teachertraining programs in PBL for all core disciplines in high school (Barrows, H.S. and Kelson, A., 1993; Savery, 2006). If the teacher chose to use PBL as one of several methods to integrate student inquiry with their current teaching methodology, then PBL is a process. The widespread adoption of the PBL instructional approach by different disciplines, for different age levels, and in different content domains has produced some misapplications in addition, misconceptions of PBL(Mansley,G., 1999). • Confusing PBL as an approach to curriculum design with the teaching of Certain practices that are called PBL may fail to achieve the anticipated learning outcomes for a variety of reasons. Boud and Feletti (1997), and Savery (2006) described several possible sources for the confusion:

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
