Prudente 2 Education Department, Bicol University Tabaco Campus, Tabaco City, Philippines Science Education Department, De La Salle University Manila, Manila City, Philippines The Peer Led Team Learning (PLTL) and 7E approaches are proven strategies in developing concepts, spatial ability, self-concept, group interaction and problem-solving skill but very few studies assessed its combined effects. The combined pedagogical approach - cognitive, psychomotor, and affective nexus needs to be assessed to support the improvement in the teaching practice of chemical bonding. Students independent variables include sex, Senior High School (SHS) track, and college entrance test science score (SS). Adapted instruments measured the dependent variables: conceptual understanding (CU), spatial ability (SA), self-concept (SC), group interaction (GI) and problem-solving approach (PSA). The score from the chemical bonding worksheet (CBW) was gathered as well. From the set of independent and dependent variables, the present study determined the relationship of sex, SHS track, SS, CU, SA, SC, GI, PSA and CBW scores. Action research paradigm was employed to 71 preservice science teachers that were divided into 10 peer groups that experienced the 30 hours activities of the CBW. The variables were tested by Pearson Correlation to show significant relationships. Results showed significant relationship between SHS track and CU, SA, SC, SS, CBW, GI and PSA. CU to SA, CBW to SA and GI, and SS to SC. Differing from most study sex was not significantly related to SA and SC. Implications of the findings to improving the CBW and teaching of chemical bonding were explained. http://pubs.sciepub.com/education/8/6/1/education-8-6-1.pdf peer led team learning 7E chemical bonding worksheets conceptual understanding spatial ability self-concept group interaction problem-solving approach
