Abstract

Although a huge number of studies enhancing pro-environmental behavior (PEB), the environmental quality is still in poor condition. Enhancing PEB needs to consider some aspects, such as the value and location. Pre-service physics teachers have a role in shaping students’ PEB because environmental issues are part of the high school physics curriculum. This study aimed to investigate the link between the location, and values (biospheric, altruistic, egoistic, and hedonic), from two different locations in Indonesia. The modified and translated 2-MEV, and E-PVQ scales were used. This study concluded that the values in both locations are in the very high category, in which the values are correlated to PEB. The strongest correlated value is an egoistic value that is related to the self-enhancement indicating the need for self-enhance approaches in the class to promote PEB. The different locations which are in the same country didn’t show a significant difference in both values and PEB. Thus, future study could conduct their research in a larger area with a different culture to explore the relationship between PEB with location or other demographic aspects, and the development of activities to enhance PEB need to consider the strong relationship between PEB with egoistic value.

Abstract

The development of this LKPD is not based on a survey or applied directly in schools, but is based on pure research results that are implemented in the field of education as one of the requirements in the preparation of the thesis. The LKPD development process in this implementation uses the ADD (analysis, design, development) stages. This LKPD uses the 2013 curriculum with KD 3.6 and 4.6. to find out the eligibility criteria for LKPD and can be accepted as valid if used in direct learning at school, it must be validated by a validator (Material and Media Expert). The final result of validation by material and media experts with a value of 72 and after being accumulated using the formula determined by the eligibility criteria, it is obtained "sufficient" on condition that the aspects that are still less than perfect are perfected.

Abstract

The purpose of this study is to determine the comparative effectiveness of the use of concept map and mind map graphic organizers on students’ learning outcomes in organic chemistry. This research adopted a quasi-experimental design involving a 3X2 pre-test post-test non-randomized and non-equivalent control group design. The study is premised on the dual coding theory of cognition, and involved 183 respondents whom were purposively selected from three intact classes. Data for the study was gathered through an organic chemistry achievement test whose reliability was determined through a test retest method and a reliability index of 0.74 was obtained. Data was analyzed using t-test and Analysis of Covariance. Findings show that there was a significant difference between the achievement of students taught organic chemistry using concept map graphic organizers and those taught with the mind map graphic organizer (F(1,118)= 7.04, p<.05). Using t-test statistics, findings also indicated that there was no significant difference in the achievement of male and female students when exposed to either concept map (t(75)= .47, p = .63) or mind map graphic organizer (t(42)= .64, p = .52). Hence, it was concluded that mind map is a more effective tool for learning organic chemistry when compared to the concept map. Irrespective of students’ gender, either of concept map or a mind map can help improve students’ achievement in organic chemistry.
