The Impact of Motivational and Cognitive Variables on Multiple-Choice Algorithmic Chemistry Problem Solving: Achievement Goal, Perceived Ability, Learning Strategy, and Self-Regulation
Jeon, Kyung-Moon ; Park, Hyun-Ju ; Noh, Tae-Hee ;
Journal of The Korean Association For Science Education, volume 26, issue 1, 2006, Pages 1~8
This study investigated the causal relationships between high school student multiple-choice algorithmic chemistry problem solving and 1) the motivational variables of achievement goal (task goal/performance goal/performance-avoidance) and perceived ability, and 2) the cognitive variables of learning strategy (deep learning/surface learning) and self-regulation. Path analysis supported a causal model in which perceived ability and task goal were found to positively influence algorithmic chemistry problem-solving ability via self-regulation. In particular it was found that perceived ability directly influenced algorithmic chemistry problem-solving ability. Moreover, deep learning was found to have been influenced by perceived ability and task goal, while surface learning was influenced by performance-avoidance goal. Lastly, there did not appear to be any causal relationship between learning strategy and algorithmic chemistry problem-solving ability.

Students have often experienced difficulties in understanding the concept of the particulate nature of matter despite its importance in chemistry. Although various instructional methods have been suggested for teaching this concept, systematic studies have been rarely conducted. Therefore, this study investigated the effects of drawing and analyzing pictures. Three classes of 7th graders at a coed middle school in Seoul were assigned to the control group, the drawing group, and the analyzing group, respectively. Students were taught about the three states of matter and the motion of molecules for 8 class periods. The instructional effects on student conception, achievement, and science learning motivation were investigated by student visual learning styles. Results revealed that the scores of a conceptions test and a science learning motivation test for both the drawing group and the analyzing group were higher than those for the control group. Additionally, the scores of the science learning motivation test were also found to be higher for students with a more visual learning style than their counterparts.

The purpose of this study was to compare student-student verbal interaction from two type's experiments; problem-solving and task-solving. For this study, five 3rd grade middle school students were selected and their verbal interactions recorded via voice and video; and later transcribed. The student-student verbal interactions were classified as questions, explanations, thoughts, or metacognition fields, which were separated into deep versus surface learning approaches. For the problem-solving experiment, findings revealed that the number of verbal interactions is more than doubled and in particular, the number of verbal interactions using deep-approach is more than quadrupled from the point of problem-recognition to problem-solution. As for the task-solving experiment, findings showed that verbal interactions remained evenly distributed throughout the entire experiment. Finally, it was also discovered that students relied upon a more deep learning approach during the problem-solving experiment than the task-solving experiment.

Most student misconceptions about evolution are similar to misconceptions and disputes which early scientists had in science history. The aim of this study was to analyze student evolution conceptions based on science history, there by revealing for effectively teaching strategies on evolution. A test was developed according to Lee's three dimensional framework (2004) on evolution concept changes. Lee's framework had been constructed according to 4 stages of evolution concept changes in history in three-dimensional aspects such as mechanism, time, and subject: before Lamarck (stage 1), Lamarck (stage 2), Darwin (stage 3), and after Darwin (stage 4). Major results were as follows. First, the evolution conceptions of students appeared fixed to stage 2 regardless of grade. Moreover, students usually possessed Lamarckian thought and did not show consistency in evolution concepts among the three dimensional aspects of mechanism, time, and subject. Therefore, students were found to apply different conceptions of evolution to each different situation.

The purpose of this study was to investigate 6th grade pupil's thoughts during classification activities. Two suitable tools in classification activity achievement were developed to achieve this purpose. The first was an artificial stimulus card in which the attribute was prominent; and the other a natural stimulus card in which the attribute was less prominent. Participants of the study were 8 6th grade pupils from D elementary school in Yeongdeungpo-gu, Seoul. Data were collected from interviews with the pupils, the pupil's recordings of classification, the investigator's observation of pupil's actions, and video recordings of the pupil's subject classification process. Results found in this study were as following. First, when doing classification 6th grade pupils considered attribute observation, attribute estimation, preliminary inspection, criteria selection, and sample identification. Second, 6th grade pupil classification thought process was found to be repetitive, passing through the steps of attribute observation, attribute estimation, preliminary inspection, criteria selection, and lastly, sample identification. Third, 6th grade pupils took advantage of cognitive economic efficiency. Study findings also revealed guidance for the teaching and learning of scientific classification. First, once teachers understand the classification thought process of students, more effective classification guidance will be possible. Second, it is necessary that guidance fit each step of the classification thought process.

Line graphs are powerful tools in conveying complicated relationships and ideas because they show the relationship that exists between two continuous variables. Also, they can show readers the variations in variables and correlate two variables in a two dimensional space, and therefore, line graphs have a significant role in physics, especially kinematics. One of the purposes of the Test of Understanding Graphs in Kinematics (TUG-K) was to uncover student problems with interpreting kinematics. The TUG-K was given to Korean college students in 2004. To what extent are Korean college students able to understand such important line graphs? Analysis of the results of the TUG-K showed in which objectives students' strengths and weaknesses are found. This study investigates Korean college students' interpretation skills of kinematics graphs and the results of the study will be used to help instructors teach kinematics graphs more effectively.

Student understanding of the nature of science is necessary not only because it is helpful for solving everyday problems with growing science literacy, but also because it influences students' science learning. Therefore, it was necessary to investigate student views on the nature of science under the 7th national curriculum and compare with those before the 7th national curriculum in order to probe the elements which contribute to changes in student views on the nature of science. A significant number of differences were found between subdimensions of views on the nature of science through the comparison. High school students under the 7th national curriculum had more relativistic, instrumental, and deductive but less process-oriented views than high school students before the 7th national curriculum. The differences between mean values which showed high school student views on the nature of science under and before the 7th national curriculum were significant, except for the subdimension of instrumentanlism/realism. In particular, high school students under the 7th national curriculum possessed a contextual view, whereas those before the 7th national curriculum possessed a decontextual view. Although other factors might be the cause for differences found in this study, we argued by discussion that differences among textbook contents seemed to be the major factor.

Oh, Jun-Young ; Kim, Yoo-Shin ;
Journal of The Korean Association For Science Education, volume 26, issue 1, 2006, Pages 68~87
The aim of this study was to understand the components that influence the mental models of preservice elementary teachers on the astronomical phenomena of seasons of the year and lunar phases of the month. For this, participants were selected from a university of education. Data was collected from a paper-pencil test and individual interviews with the participants. The results of this study showed that the preservice teachers had apparent synthetic mental models, and that the 'Distance Theory' and 'Occlusion Theory' had the greatest effect on their mental models. Furthermore, it was found that preservice elementary teachers' initial mental models of 'astronomical phenomenon' had their origin in personal belief sets (specific theory) related to 'astronomical phenomenon'. It was on these belief sets that they interpreted their observations and cultural information with the constraints of a naive framework of physics. The structures and possible sources for overcoming these synthetic mental models were also discussed in this paper. Lastly, implications for preservice elementary teacher education were presented.

The purpose of this study was to analyze the process of scientists' science knowledge generation by employing four creative scientists as participants. Raw protocols were collected by an intensive interview method and then analyzed by a psychological modelling procedure. The present study showed that the process of knowledge generation divided into the processes of inductive, abductive, and deductive thinking. Furthermore, the inductive process in simple and operative observation was involved in the processes of generating a question, conjecture/prediction, designing an operational method, operation, and simple observation. Also, the abductive process had two components; question generation, and hypothesis generation which consisted of analyzing questions, searching explicans, and constructing hypothesis. Finally, the deductive process involved inventing abstract test methods, inventing abstract criteria, inventing concrete test methods, inventing concrete criteria, collecting results, and evaluating hypotheses and stating conclusions.

In this study, Korean middle school student science achievement results in the "Trends in International Mathematics and Science Study" (TIMSS 2003) were analyzed according to international benchmarks, content area, gender and student attitudes toward science. Overall Korea ranked the third internationally and had a mean score of 558. Korean students achieved top ranking in physics, but fell to the ninth place in chemistry. Unliked their counter parts in similar countries such as Singapore and Chinese Taipei, Korean students did not reach the highest benchmark. Compared to previous assessment, Korean girls showed improved performance; however, significant gender differences still exist in Korea; apparent from the better performance of boys than girls in the study. It is also noteworthy that Korean students were found to have the lowest self-confidence in learning science, a lower valuing science, and less enjoying learning science even though they produced high achievement scores.
