<p>This research aims to apply and find out the characteristics of Problem-Based Instrumental Analysis of Chemistry Lab Work Learning Model (IACLLM) which is able to build the characters, improve the conceptual mastery and the ability of problem solving. The research using experimental quasy with 2 student groups of pre service chemistry teachers as the subjects of the research applied the treatment of problem-based IACLLM for the experimental class and lab work learning with standard lab work procedure in control class. Conceptual mastery was measured using essay test; problem solving skills were measured using assessment of problem solving reports, presentation of the results, and kit making products; whereas the emerged characters were observed during the learning process. The result of this research showed that problem-based IACLLM had open-ended problem characteristic, had produced local material kit, and characters were observed in every stage of problem-based learning model. The implementation of the model could improve the spectrometric and electrometric conceptual mastery, the problem solving skills on a very good level and also some characters were developing during learning process, including religious, discipline, honest, curious, creative, critical, cooperative, communicative, independent, and able to appreciate other people’s opinions and achievements, leadership, democracy, and able to be thorough and careful, and hardworking.<br /><br /></p>

The environmental education course currently does not integrate problem-solving problem skills. The purpose of this study was analyzing the results of applying integration on problem-based learning with the RMS (reading, mind mapping, and sharing) learning model. The research method was a quasi-experimental with pre-test-post-test control group design. The study was conducted on 56 students who took an environmental education course in Natural Science Education Universitas Tidar. Data analysis used an Anacova test with a pretest as its covariate. The study results stated that 1) developed learning model integrates PBL with RMS learning model consisting of identifying problems, finding relevant information about problems through reading activities, analyzing problem: group discussion through mind mapping, providing solutions, and sharing results of mind mapping. 2) The integration of PBL with the RMS learning model indicated by an average score of post-test in the integration of PBL with the RMS learning model class of 68.46, and the traditional class of 48.92. 3) the learning process that occurs in the integration of PBL with the RMS learning model class shows that learning is run well, which is indicated by students' average evaluation score of the lecturer learning process. The integration of PBL and RMS model can be utilized by teachers and lecturers in Biology learning to have thinking skills and solve daily problems.

This research aims to improve senior high school students’ physics problem-solving skills through learning used IBMR learning model. This research was a pre-an experimental study with a one-group pre-test and post-test design. The Methods of data collection used validation and test. The materials used to teach were valid category by two experts and can be used to practice physics problem-solving skills. The average post-test score physics problem-solving ability was 73.24 with an N-gain of 0.59 was classified as moderate. The success of IBMR learning model-based devices in practicing problem-solving abilities can be seen in the increase in the average score in each indicator of problem-solving abilities. The indicator of understanding the problem had the highest post-test average score of 94.58 with an N-gain of 0.89 in the high category. The problem-solving indicator had the lowest posttest average score was 58.22 with N-gain 0.39 and mean that it was the moderate category. Based on the results study, it can be concluded that the learning used by IBMR learning model can practice the ability to solve physics problems on heat material and its displacement. Learning with the IBMR learning model was expected to train students in solving physics problems. The stages in the IBMR learning model can help students

Aim/Purpose: Within higher education, graduating students who are able to solve ill-structured, complex, open-ended, and collaborative, workplace problems is recognized as paramount. Because of this, there is a need to assess this skill across the curriculum. Background: This paper addresses this issue by assessing problem-solving across a computing curriculum using an assessment instrument shown to be reliable and valid. Methodology: The method is based upon the implementation of the assessment instrument that uses a scenario-based asynchronous discussion board measuring the ability of student groups to solve workplace problems. The sample are computing students from the 2nd, 3rd, 4th year, and master’s levels at a UAE university. Contribution: This paper shows the problem-solving skills of students over four years of study across a computing curriculum and demonstrates the effectiveness of the instrument. Findings: There was a general increase in student problem-solving performance from the 2nd, 3rd, 4th year, and master’s levels, but students often failed to meet the expected level of performance for their year of study. In addition, the instrument was effective in assessing problem-solving. Recommendations for Practitioners: This assessment instrument, or one similar, that uses a scenario-based asynchronous discussion board can be used to measure the ability of student groups to solve workplace problems. Impact on Society: Students must be prepared to solve workplace problems to meet the needs of 21st century employment. Future Research: Further research should be conducted with this assessment instrument, or one similar, outside of this fairly unique UAE- based context.
