TL;DR: The variations of antioxidant enzyme activities and lipid peroxidation (LPO) levels were investigated in all Mentha pulegium organs grown in the excess and absence of Ca2+, Mg2+ as macronutrients; Cu2+, Zn2+ and Mn2- as micronutrient and control conditions.

TL;DR: In this paper, the effectiveness of instruction via newly developed teaching materials based on cooperative learning when compared to a traditional approach, on ninth grade students' understanding of metallic bonding was investigated, where the same teacher taught metallic bonding with cooperative learning to an experimental group and with a traditional teacher centred approach to a control group (N = 29).

TL;DR: The effect of diets containing antioxidant vitamins and trace elements on chicken tissue activities of SOD, CAT, GSH‐Px and of LPO levels was investigated.

TL;DR: In this paper, the authors investigated the degree of effectiveness of cooperative learning instruction over a traditional approach on 11th grade students' understanding of electrochemistry and found that instruction for the cooperative group was more successful in remediation of the predetermined misconceptions.

TL;DR: In this article, the effects of inquiry-based laboratory activities on high school students' understanding of electrochemistry and attitudes towards chemistry and laboratory work were investigated, and the results indicated that instruction based on Inquiry-Based Laboratory Activities (IBLA) caused a significantly better acquisition of scientific concepts related to Electrochemistry, and produced significantly higher positive attitudes towards Chemistry and laboratory.
