Background: This study aims to develop and produce a diagnostic tool capable of detecting student misconceptions on the concept of ecosystems. Methods: This study used a research and development method with a modified 4D design (Define, Design, Develop and Disseminate) without disseminating or spreading. Data collection methods used in this research and development are observation, literature review, documentation, questionnaires, interviews and tests. Results: The results showed that the instruments developed were valid by validating 3 experts, namely material experts, evaluation and assessment experts, and linguists with an average percentage of each feasibility of 90% material expert judgment, 82% assessment expert assessment and evaluation. and 80% linguist assessment. Meanwhile, the instrument readability test showed a percentage of 63% in good category. The validity value of the instrument in general was 0.70 with the valid or high validity category, while the instrument reliability value was 0.82 with the very high category of reliability. The overall results of students' misconceptions on ecosystem material showed 23% of students experienced low-category miconceptions, 8% of students experienced no conceptual understanding, 17% of students experienced conceptual understanding, and 52% of students experienced partial understanding. Conclusion: Based on these results it can be said that the four-tier test instrument developed is feasible and can diagnose misconceptions in students

Kata Kunci: Software Anti Mischem, Reduksi Miskonsepsi, Hidrolisis Garam, Conceptual Change Text. Abstract Research development aims to determine the feasibility of developing anti- mischem software as a medium to reduce students misconceptions in hydrolysis of salt with conceptual change text strategies. Feasibility anti-mischem software in terms of three aspects that is: (1) content validity and construct validity of antimischem software from the results of validation by the validator, (2) practicability of anti-mischem software determined by the outcome of student response and supported by observation result of students’ activities, (3) the effectiveness of anti-mischem software is determined from the shift in students’ understanding of concepts from misconceptions to understanding concepts. This study using a method of Research and Development (R&D). Research subject used were 15 students 11th grade science at SMAN 1 Krembung Sidoarjo. The results of the research that have been done, obtained an average percentage of the results of content validation of 84,44% and construct validation of 82,74% which fall into the very valid criteria. The results of the average percentange of students responses of 92,59% and observations of student activities of 92,50% which fall into very practical criteria. The results of the shift in understanding the concept of students obtained an average of 83,65% which is included in the criteria very effective, so it can be concluded that anti-mischem software that has been developed can be declared as a medium to reduce the student misconceptions on hydrolysis of salt using conceptual change text strategy.

The Relationship

In chemistry, an abstract material consists of three levels of representations that are macroscopic, sub-microscopic, and symbolic. However, many students have misconceptions due to the difficulty in understanding the relationship between the three levels representations. Misconceptions should be reduced or prevented as early as possible because it is resistant and difficult to change. Stoichiometry represents one example of chemistry material which consists of abstract concepts that usually lead to student misconceptions. The misconception in this material can be reduced if the wrong concept has already detected. Therefore it needed the tool that can detect and reduce these misconceptions. Software can be used as the tool to detect and reduce misconception because it has two functions as assessment and learning tool. Software must be said effective before it is used by student. So that this study aim is knowing the effectiveness of software to detect and reduce misconceptions in stoichiometry material. This study used Research and Development method. The result of this study shows that software is effective to detect and reduce misconceptions. It is proved by the average percentage of misconception shift to understand the concept about 80,13% which is categorized as effective.

There are limited studies on the diagnosis of heat and temperature misconceptions using a four-tier instrument diagnostic test. Therefore, this study aims to identify misconceptions in heat and temperature material. The survey research was conducted on 164 students at SMAN 2 Bantul. Students were selected using a convenience sampling technique. Identification of student misconceptions using the Four Tier Heat and Temperature Diagnostic Test (4T-HTDT). Students' conceptual understanding is calculated using the percentage technique. The results of this study indicate that there are still many students who have misconceptions on the concept of "heat-temperature as an extensive quantity" and "heat-temperature depends on material objects". The findings are expected to be a strategic step for designing appropriate remedial teaching.

Learner Worksheet (LKPD) of reaction rates based structured inquiry in class XI SMA had been dertemine validity and practicality. The type of research used is Research and Development (RD). The development model was a 4-D model consisting of 4 stages, namely (1) Define, (2) Design, (3) Develop, (4) Desseminate. The disseminate stage was not carried out due to time and cost constraints. The research instrument used was a questionnaire validation and practicality questionnaire. The validation questionnaire was filled by 3 chemistry lecturers from FMIPA UNP and 2 chemistry teachers from SMAN 2 Lubuk Basung. Practicality questionnaire was filled by 2 chemistry teachers and 30 students of class XII MIPA 3 SMAN 2 Lubuk Basung. Data were analyzed using kappa moments. The average kappa moment of validity test was 0.87 with a very high validity category. The average kappa moment of teacher were 0,88 with a very high practicality category. The average kappa moment of student were 0,87 with a very high practicality category. Thus, it was concluded that reaction rates LKPD based on structured inquiry was valid and practice.
