Forty-eight balanced low and high difficulty problems were designed. Fifteen undergraduate students majoring in chemistry (8 females and 7 males) participated in the study. Results demonstrated significantly increased reaction time, significantly decreased accuracy, and highly significantly elevated subjective effort as task difficulty intensified. ERP analysis revealed significant differences in N200, P300, and N400 amplitudes between easy and difficult problems, indicating increased demands on control, working memory, and in-depth processing under high load. The study provided physiological evidence supporting cognitive load theory and offered implications for optimizing oxidation-reduction reaction teaching. The findings bridged the gap between cognition and education, suggesting potential avenues for improving chemistry education through cognitive load management.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">92-104</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Fayadh Hamed Alanazi</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">BRAIN-BASED LEARNING AS PERCEIVED BY SAUDI TEACHERS AND ITS EFFECT ON CHEMISTRY ACHIEVEMENT OF 7TH GRADERS</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Baltic Science Education</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">brain-based learning</style></keyword><keyword><style  face="normal" font="default" size="100%">chemistry learning</style></keyword><keyword><style  face="normal" font="default" size="100%">chemistry teaching</style></keyword><keyword><style  face="normal" font="default" size="100%">grade 7</style></keyword><keyword><style  face="normal" font="default" size="100%">SCIENCE teachers</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2020</style></year><pub-dates><date><style  face="normal" font="default" size="100%">December/2020</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2020/987-1606572205.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">19</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This research explored science teachers’ perceptions of BBL. Data was collected from 105 Saudi Arabian science teachers via a questionnaire survey, establishing how BBL is viewed and applied, and whether this interrelates with teachers’ years of professional experience or qualification level. Furthermore, in a quasi-experiment comprising a single experimental group, a chemistry learning unit was designed using BBL methods and approaches and was delivered to 26 Saudi Arabian Grade 7 students. Pre- and post-lesson measurements of knowledge and achievement were conducted. The findings confirm the arguments in the BBL literature and show that BBL awareness is relatively high and BBL is viewed very positively. The results of the quasi-experimental component show that BBL methods are likely to improve student learning and outcomes. Teacher qualifications and years of experience were unrelated with BBL perceptions.</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">864-874</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Špela Hrast</style></author><author><style face="normal" font="default" size="100%">Ferk Savec, V.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">INFORMATIONAL VALUE OF SUBMICROSCOPIC REPRESENTATIONS IN SLOVENIAN CHEMISTRY TEXTBOOK SETS</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Baltic Science Education</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">chemistry learning</style></keyword><keyword><style  face="normal" font="default" size="100%">chemistry textbook sets</style></keyword><keyword><style  face="normal" font="default" size="100%">informational value</style></keyword><keyword><style  face="normal" font="default" size="100%">submicroscopic representations</style></keyword><keyword><style  face="normal" font="default" size="100%">textbook analysis</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2017</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2017</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2017/987-1509213895.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">16</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This research focuses on the informational value of submicroscopic representations (SMRs) in chemistry textbook sets for Slovenian primary schools (Grade 8 and Grade 9, students’ age 13-15 years). For the purpose of analysis a holistic criteria related to the accompanying descriptors of SMRs in textbook sets was developed. The research revealed four main holistic descriptors accompanying SMRs, i.e. direct descriptor (D), indirect descriptor (I), combined descriptor (C), and SMRs without descriptors (W), which support learners’ recognition of SMRs’ informational value on different levels by providing different accompanying add-ons of SMRs. In-depth analysis identified 14 main categories of the underlying representational types of SMR add-ons. The significance of the research is in initiating a discussion about the holistic criteria for the description of SMRs integrated in the textbook sets, because in practice the learner perceives each SMR as a whole.</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">694-705</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Kamisah Osman</style></author><author><style face="normal" font="default" size="100%">Wahidin</style></author><author><style face="normal" font="default" size="100%">Subahan Mohd   Meerah</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">CONCEPT MAPPING IN CHEMISTRY LESSONS: TOOLS FOR INCULCATING THINKING SKILLS IN CHEMISTRY LEARNING</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Baltic Science Education</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">chemistry learning</style></keyword><keyword><style  face="normal" font="default" size="100%">concept mapping</style></keyword><keyword><style  face="normal" font="default" size="100%">scientific thinking skills</style></keyword><keyword><style  face="normal" font="default" size="100%">vee diagram</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2013</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2015/987-1425810723.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">12</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The aim of this study is to investigate the combination effect of concept mapping and vee diagrams as thinking tools in Chemistry among some 360 secondary students in Indonesia. This study employed a quasi-experimental approach whereby students were segregated into three intervention groups: concept mapping, vee diagram and thinking skills embedded throughout the lesson (E1), concept mapping (E2) and a conventional approach (E3). Students were also characterized in terms of their ability: High (H), Moderate (M) and Low (L). Students’ thinking skills were measured using a modified version of the Test of Integrated Process Skills (TIPS), which has beed systematically justified in terms of reliability and validity. Analysis of findings reveal that the EI approach is the most effective technique in inculcating students’ thinking skills. A series of follow-up analyses also demonstrate that the E1 approach is best suited for the high ability (H) students as compared to their moderate (M) and low (L) ability counterparts. </style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">666-681</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Almeda Kuriene</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE ESTIMATE OF LEARNING OF PARTICIPANTS OF CHEMISTRY OLYMPIADS</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Baltic Science Education</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">chemistry learning</style></keyword><keyword><style  face="normal" font="default" size="100%">participants of olympiads</style></keyword><keyword><style  face="normal" font="default" size="100%">senior students motivation</style></keyword><keyword><style  face="normal" font="default" size="100%">students’ progress</style></keyword><keyword><style  face="normal" font="default" size="100%">teaching subjects</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2002</style></year><pub-dates><date><style  face="normal" font="default" size="100%">March/2002</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2017/987-1504180449.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">1</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The aim of this paper is to evaluate the progress and to attitude the chemistry learning of Olympiads participants.

 

The research was conducted among the participants of 38th, 39th Lithuanian Pupils’ Olympiad of Chemistry which took place in 2000, 2001.

 

On the basis of this research it can be concluded that the knowledge in principal subjects (mathematics, physics, foreign language and Lithuanian) of 69,5% of participants is graded in 8-10 points. Chemistry results of the second trimester by 83,1% of respondents is graded in 10 point, by 14,1% – in 9 point. 97,7% of participants consider chemistry to be their favourite subjective and exact and natural sciences to be more interesting than humanitarian.
