Abstract This research aimed to describe undergraduate students’ misconception about projectile motion after learning physics during the Covid-19 pandemic era. This research was qualitative research with a descriptive method. The subjects were 52 first-year undergraduate students who took physics courses. Data collecting methods used in this research were a test, questionnaires, and interviews. The test was taken from Physics by Giancoli with an additional question about certainty of response index (CRI). Data from the test were analyzed by categorizing it into lack of knowledge, knowledge of correct concepts, and misconception while open-ended questionnaires and interviews were used to help to clarify the condition. The test results indicated that 5.13% of students in lack knowledge, 28.85% the knowledge of correct concepts, and 66.02% in misconception. The questionnaire responses showed that students learned physics via online meeting with direct instruction model and ask-answer method, exercised with only applied problem (C3), and virtual practicum. The interviews showed that only a few of the students learned physics and responded to the lecturer during the online meeting. The results are that the majority of first-year undergraduate students are in misconception after learning physics during the Covid-19 pandemic era and need remedial learning about projectile motion.

Biological Phenomena

Research in developmental psychology has shown that deeply-rooted, intuitive ways of thinking, such as design teleology and psychological essentialism, impact children’s scientific explanations about natural phenomena. Similarly, biology education researchers have found that students often hold inaccurate conceptions about natural phenomena, which often relate to these intuitions. In order to further investigate the relation between students’ conceptions and intuitions, we conducted a study with 93 first year undergraduate students in biology. They were asked to express their level of agreement or disagreement with six misconception statements and to explain their choices in a two-tier test. Results showed a tendency for students to agree with teleological and essentialist misconceptions. However, no association was found between students’ teleological and essentialist conceptions as expressed in their agreement or disagreement with the various misconception statements. Moreover, we found evidence of a variable consistency across students’ answers depending on the misconception considered, which indicates that item features and contexts may have an effect on students’ answers. All together, these findings provide evidence for considerable persistence of teleological and essentialist misconceptions among students. We suggest future directions for thinking, studying, and analyzing students’ conceptions about biological phenomena.

Abstract Undergraduate students majoring in mathematics often face difficulties in comprehending mathematical proofs. Inspired by a number of studies related to students’ proof comprehension, and Mejia-Ramos et al.’s study in particular, a test was designed in relation to the proof comprehension of the Cauchy Generalized Mean Value Theorem (CGMVT). The test mainly focused on (a.) investigating students’ understanding of relations between the statements within the CGMVT proof and (b.) the relations between the CGMVT and other theorems. Thirty-five first-year university students voluntarily participated in this study. In addition, 10 of these students were subsequently interviewed to seek their opinion about the test. Test results indicated that most of the students lacked an understanding of the relations between the mathematical statements within the CGMVT proof, and the relations between the CGMVT and other theorems. The results of interviews showed that this type of assessment was new to students and helped them to improve their insights into mathematical proofs. The findings suggested such a test design could be used more frequently in assessments to aid instructors’ understanding of students’ proof comprehension and to teach students how mathematical proofs should be learned.

This research applied qualitative research which used descriptive method in order to analyze the use of intuition physics of students in solving physics problems. This research was conducted at SMA Al Azhar Palu. The subjects of this research are nine students, they are divided by three categories which are the high, middle and low categories. The average value obtained from the respondents' test results was 43,46 and the standard deviation was 21,71. Respondents with a high category are respondents who are above the value of 65,17. The instruments of the research used are the respondent selection test, analyzing the use of intuition physics and interview guidance. Data were collected through thinking-aloud activities, which of respondents do a test then write the answers on a paper while expressing matters related to what was written and recorded that using a handycame. Interviews were conducted as supporting data in analyzing the results of thinking-aloud. Based on the analysis of data, it is obtained by the model of intuitions physics which contains the p-prims. It consists of cuing priority, reliability priority and the conclusion.The use of appropriate physics intuition is useful to help students apply their mathematical skills in solving physics problems. The proper physics intuition model is through all stages of the p-prims elements obtained through student learning experiences related to physics. It is necessary to develop learning that considers the importance of using physics intuition as a performance framework for evaluating the progress of students' problem solving processes better and more productively.

This study examined whether the modality principle occurs or not in the learning of C++ computer programming using screencasting. According to Mayer and Clark (2011), the modality principle is defined as presenting words as speech rather than on-screen text is more effective in learning. In other words, the learning process will be more effective when information is explained by audio narrations rather than on-screen text. A true experimental pre-test and post-test research design was conducted to determine the modality effects. The experiment consisted of 65 first-year undergraduate students (aged 19-22) who have never attended any formal computer programming course prior to the study. The sample were randomly assigned to two groups: the first group received the screencasting and narration (SN) mode whereas the second group received the screencasting, text, and narration (STN) mode. After that, pre-test was conducted to ascertain their score before being exposed to the treatments. The pre-test results were used as covariate in the two-way ANCOVA analysis. Results showed that the SN mode students outperformed the STN mode students in the post-test. The significant outcome of the result might be due to the effectiveness of the SN mode that supported the Modality Principle.

Extra tutorial sessions on the use of pictorial mnemonics to facilitate memorization of Japanese hiragana and katakana script characters, as well as vocabulary words and kanji characters, were offered to university first year undergraduate students taking a beginners’ Japanese language course. 27 students, most of whom were experiencing some difficulties with the course, volunteered to attend. Although the improvement in actual marks that the students evidenced subsequent to attending the sessions did not prove to be statistically significant, a significant improvement in pass rate was found. Furthermore, the students rated the sessions highly in terms of their helpfulness, and the majority indicated that they believed the sessions helped their performance in the course assessments. It is concluded that mnemonic strategies can effectively be employed in facilitating retention of the script of a foreign, non-alphabetic language within a real educational setting. 初心者対象の日本語コースを取っている大学１年生に、日本語のひらがなとカタカナ、及び語彙と漢字の記憶を促進するため、絵を用いた連想法を使った追加授業が提出された。２７名（そのうちのほとんどは、コースにおいて何らかの困難に直面している）が自主的に追加授業に出席した。追加授業出席後、学生の実際の小テストの点の向上には有意差は認められなかったものの、合格率の向上においては有意差は確認された。さらに、追加授業に出席した学生は授業が役立ったと高く評価し、大多数が追加授業がコースの成績の成果に貢献したと思うと述べた。本論は、実際の教育現場で英語のアルファベットを用いない外国語の文字を教える際、連想法を効果的に使用することができると結論づけた。
