Abstract

This study aims to compare the effectiveness of guided inquiry, open inquiry, and tiered inquiry in biochemistry learning. The effectiveness is seen from the product-process perspective, i.e., by looking at critical thinking scores and responses of lecturers' teaching activities. This study involved three groups treated with guided inquiry (level 1), open inquiry (level 2), and tiered inquiry (level 1 to level 2). The number of respondents was 72 students spread over the three groups. Before being given treatment, the three groups were tested for prior knowledge, and it was obtained that the three groups had the same initial ability. The research instrument used was critical thinking questions and a questionnaire of responses to the learning process. The results showed that the group with tiered inquiry treatment had the highest critical thinking score, while open inquiry had the lowest score. It is in line with the respondents' responses related to the learning process. Students feel easier and more comfortable in the tiered inquiry process than the guided and open inquiries. The results of the Mann-Whitney U test analysis on the three treatments showed that the three groups had significantly different critical thinking scores. It can be concluded that tiered inquiry is more effective in Biochemistry learning than guided and open inquiries.

Abstract

The COVID-19 pandemic has changed the face-to-face learning process to online learning. It requires learning innovations that can make students more independent in exploring concepts. Case-based learning can be an alternative in the online learning process. This study aims to develop a case-based learning model in online biochemistry learning. This study uses six stages to modify the stages of development research. The results showed that the learning model developed consisted of five phases which became the syntax of the learning model developed, namely (1) Planning; (2) Orientation; (3) Organization; (4) Implementation; and (5) an evaluation developed following the results of the needs analysis. The developed syntax is described in model implementation guidelines and is equipped with learning tools. The validator's assessment shows that the model and device instructions have an index value of the expert agreement with a valid category. The test results on students showed that all the stages described in the guidelines could be implemented properly. Students gave a positive response to the implementation of case-based learning. Thus, case-based learning can be recommended for further learning.

Abstract

Corrosion inhibitors of 2-isopropyl-5-methylphenol and its derivatives has been elucidated by means of density functional theory at B3LYP/6-31G(d) level of theory. Effect of electron donating and withdrawing groups such as NH2, SH, CHCH2, CH3, OH, CHO, COOH, F and NO2 on the corrosion inhibitor of 2-isopropyl-5-methylphenol derivatives also have been studied. The quantum chemical parameters such as the frontier orbital energies (EHOMO), ionization potential (I), electron affinity (A) and electronegativity (χ) are closely related to the corrosion inhibition efficiency (IE %) of 2-isopropyl-5-methylphenol derivatives. The presence of electron donating groups increase IE % values meanwhile electron with drawing groups reduce IE % values. The enhancement of IE % follows NO2 < CHO < COOH < SH < F < CH3 < CHCH2 < OH < NH2. Electron donating NH2 group gives 96.38 % of IE %, pure 2-isopropyl-5-methylphenol IE % = 82.70 %. In contrast, electron withdrawing NO2 group gives IE % only 68.66 %. This theoretical study would have a significantly contribution for accelerating corrosion inhibitor experimental to gain optimum results.
