The purposes of this research study were to develop solving-problems in science learning approach with the Problem-Based Learning (PBL) instructional lesson plans to enhance students’ learning achievements and their solving-problem abilities in science with the efficiency of the processing performances and the performance results (E1/E2) at the determining criteria as 80/80, students’ learning achievements of their post assessing test and the criteria learning outcomes at 80% with the PBL, and students’ solving-problem abilities and the criteria learning outcomes at 80% with the PBL toward science were compared, and to associate between students’ learning achievements and their solving-problem abilities with the PBL was analyzed. Administrations with a sample size which consisted of 48 lower secondary educational students at the 9th grade The aims of this research study were 1) to develop activity-based learning conceptual approach with the STEM Education instructional method on the Less
