Abstract
Geoscience is a study of earth, it is easy to find around everyday student’s ;ife. The aim of this research is to develop Geoscience Students Worksheets based on scientific work to enhance students scientific work and conceptual mastery also to test the validity of the Geoscience Students Wroksheets through experts appraisal and students response. This reasearch is R & D research using 4D model until Develop stage. Data collection techniques including survey and interview technique. The question in the questionnaire consists on closed ended and open ended, the close ended question it to measure the validity and students response while open ended question for obtaining suggestions from all experts and students. Moreover, interview conducted during preliminary study. There are two validators in this research, they are content and learning media expert with Science Education educational background. In addition, ten students respondents in this research are already took the Geoscience Course last year. Quantitative data was analyzed by comparing the score with certain criteria and qualitative data was analyzed with finding common topics. Validation result and students respon results show that Geoscience Students Worksheets is very valid with score from content expert, learning media expert, and students consecutively 90,01%, 85,70%, and 89,4%.
Highlights
Geoscience is the scientific study of earth, including geology, geochemist, geophysics, paleontology, and other disciplines to earth's condition in the past, present, and future
Some weaknesses in geoscience teaching and learning are the unclear purpose of the study (Neenan, 2016), class basedlearning (Waldron et al, 2016), the lack of industrial demand skills (Mikes, 2015), and it is for students to gain misconceptions (King 2008)
Some problems were found in this part of the research namely: the lack of student interest and scientific work during Geosains classes
Summary
Geoscience is the scientific study of earth, including geology, geochemist, geophysics, paleontology, and other disciplines to earth's condition in the past, present, and future. This point of view is based on the dynamic climate condition (King, 2019). It still becomes an interesting discussion topic regarding recent research findings suggest implement a different way of teaching it. This suggestion appears because previous learning activities are not relevant to the job demand nowadays (Mikes, 2015; Neenan, 2016). The finding from the preliminary study students tends to memorize than understanding, even though they know that basic process will guide to advance mastery of every subject
