The design of this study was quasi-experimental with the nonequivalent control group. The samples consisted of the students of VII A (experimental class) and VII B (control class) selected using a purposive sampling technique. Data were collected through observation and tests. The results showed that the value of the correlation coefficient obtained based on the posttest of students' problem-solving skills was r = 0.728. Moreover, the t-test analysis on the value of the correlation coefficient of problem solving skill scored t count = 6.58, which indicated the existence of a dependent influence or relationship. The significance of the effect was seen from the coefficient of determination score of 56.25%. Besides, there were 75% of the students gave a positive response to the learning process. Thus, it concludes that the PBL on heat and its transfer topic has affected the students' problem-solving skills.","PeriodicalId":30735,"journal":{"name":"USEJ Unnes Science Education Journal","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75379274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of this study revealed that teachers’ undesrtanding has limited description of the components of inquiry based instruction to only posing and answering the questions in science classroom. They failed to decribe all components of inquiry based instruction as listed in competence based curriculum as the vehicle of the entire learning and teaching process which lead to insufficient understanding of inquiry based instruction. Their self-efficacy for inquiry based instruction is high and their actual implementation is at lowest level, none of the components of inquiry science classroom has implemented by participating teachers.

The results of observation at SMP N 2 Sukolilo showed that there was no task or question which was specifically used to measure HOTS of the students. The aim of this study is to analyze the characteristics of two-tier multiple choice assessment instrument and HOTS ability of the students. This research was conducted by using Research and Development (R&D) method. Samples were taken by random sampling technique from the population of class IX students of SMP N 2 Sukolilo in the academic year 2019/2020, then class IX C was selected for small-scale trial, class IX B was selected for large-scale trial, and class IX A was selected for trial use. Data was taken by some methods such as test, questionnaire, and documentation. The characteristics of two-tier multiple choice assessment instrument was analyzed by expert judgment and empirical testing. Whereas, HOTS level of the students was analyzed using the HOTS Category Scale. The results of the analysis of the characteristics of two-tier multiple choice assessment instrument indicated that the developed instrument had fulfilled the requirement as a good instrument, namely (1) valid, with the result of expert validation as many as 79% (feasible) and the results of the item analysis was 0.49 (sufficient ); (2) reliable, with the reliability result was 0.40 (reliable); (3) relevant, representative, practical, and specific as indicated by the results of the teacher's questionnaire responses with the percentage 75% (good); (4) discriminatory power, with the average of analysis result was 0.36 (good); and (5) proportional / difficulty level, with the analysis result of most questions in the moderate category. Furthermore, the analysis results of HOTS level of the students showed that the students on the large-scale trial were mostly in the moderate category (67%) and some of them in a small portion were in the low category (33%). While, HOTS level of the students on the trial use showed that most of the students were in the moderate category (50%), some of them were in the low category (30%), and a small portion of them were in the high category (20%).
