The objectives of this study were to analyze the validity, practicality, and effectiveness of South Kalimantan local wisdom-based biology learning and its effect on student learning outcomes. The research method used is research and development. This research was in a Develop stage of Thiagarajan’s Model. This development has produced learning models (lesson plans, student’s worksheet, learning achievement test questions, teacher activity sheets, student activity sheets, and student response sheets). The local wisdom-based learning model were designed with seven stages using Banjar language (regional language of South Kalimantan). Model that have been developed were tested for the level of validity, practicality, effectiveness, and its effect in learning. The level of validity is determined based on the assessment and review of the four validators. To find out the effectiveness and the effect of the learning model, quasi-experimental design was applied by involving two classes at SMAN 7 Banjarmasin-Indonesia. Data were collected using a variety of instruments, namely the validity assessment sheet, the student’s worksheet and lesson plan sheets, student achievement test questions, and student response sheets. Data analysis was implemented to measure the effectiveness and the effect of learning by calculating n-Gain and ANCOVA, respectively. The results, the learning tools met the "valid" criteria so that it can be implemented. Learning also concluded having good practicality criteria. Moreover, it can be seen that the application of local wisdom-based learning model and tools was quite effective in improving student learning outcomes, in contrast to learning in the control class. Furthermore, ANCOVA test concluded that there were significant differences in learning outcomes between students in the experimental and the control class.

This study was intended to display the role of eco-school program (Adiwiyata) towards environtmental literacy (EL) of high school students by analyzing, (a) EL of students in Adiwiyata and non-Adiwiyata high schools, and (b) EL of students in Grade X and XI, Adiwiya and non-Adiwiyata high schools in Malang-East Java, Indonesia. The survey involved 275 students. The respondents were from four state high school i.e. SMAN 1, SMAN 3, SMAN 4, and SMAN 7. Data were taken via MSELS questionnaire that was modified and filled online. Aspects of EL include ecological knowledge, environmental affect, cognitive skills, and behavior. The results of multivariate analysis showed that the level of students’ EL was significantly influenced by school type and grade. However, the interaction both of them had no significant effect on their EL. Univariate results on school type factor informed that significant differences occured in all aspects of EL, where the lower identified level of students in Adiwiyata schools compared to Non-Adiwiyata was only in the environmental affect. On the other hand, the significant influence of grade level only occurred in cognitive skills aspect. Broadly speaking, all data analyzes concluded that the application of the Adiwiyata program was able to bring a positive impact on the level of students’ EL. There was also a tendency that the higher the student's grade, the better their EL level.

The pandemic case has shifted away from face-to-face teaching to online blended learning. This phenomenon certainly causes various problems in the world of education. The online blended learning is good when applied with good internet connections and complete facilities. However, it differs from Indonesian coastal students who do not have supporting facilities. Therefore, this research aims to analyze the experience and readiness of Indonesian coastal students. It determines the facilities of the process using qualitative research with a phenomenological approach. Purposive sampling was used to collect data from 25 students living in coastal areas in Aceh, Indonesia. Furthermore, in-depth interviews were used to obtain instruments and techniques for data collection, observations, field notes, and audio-visuals. Data analysis was carried out qualitatively by reducing, displaying, drawing conclusions, and verifying data. The data processing was conducted using NVivo 12 plus software. The kappa coefficient is used to check the accuracy of the data since there was no bias during coding. The analysis results show that Indonesian coastal students are not ready to conduct the online blended learning process. Furthermore, it is recommended that future research focus on coastal students’ development. A Hypothetical Learning Trajectory design should be created to assist in independent learning and lessen their readiness.
