Abstract

Misconceptions are one of the causes of students learning difficulties. One of the misconceptions about chemistry is the atomic structure. In general, chemistry subjects are abstract and difficult to visualize. It causes students to find it difficult to understand chemical concepts correctly. Misconceptions that occur in students will have an impact on understanding further material. Therefore, it is necessary to do an analysis to identify students who experience misconceptions so that efforts can be made to prevent and correct them. Misconceptions experienced by students can be identified through diagnostic tests, one of which is the five-tier diagnostic test. Most of the five-tier diagnostic tests used are narrative-based, which triggers student saturation. Therefore, this study uses a five-tier diagnostic test combined with a pictorial test. This research is to find out students misconceptions experienced by X-class SMA in the matter of atomic structure. This study uses a quantitative descriptive method. The instrument used in this study was a pictorial-based, five-tier diagnostic test consisting of 24 items. The results showed that students experienced misconceptions about atomic structure material with an average percentage of 20%. Students experience misconceptions about the concept of the development of atomic theory (18%), atomic constituent particles (23%), isotones, isobars, and isotopes (21%), and electron configurations (20%). Factors that cause misconceptions experienced by students include their prior knowledge, their interest in studying atomic structure material, the sources of their personal thoughts, their low ability and reasoning in understanding atomic structure material, and their lack of instilling concepts in them.

Abstract

Curriculum, learning, and assessment are the main keys to educational success. Formative assessment is an interactive strategy to identify what must be learned and how teaching is formulated according to educational needs. The questionnaire results show that chemistry teachers in schools still do not utilize formative assessments to measure the progress of the educational process. This research aims to collect information regarding the need for developing formative assessments for problem-based learning to improve students' critical thinking skills in the sub-material of vapor pressure reduction. A qualitative method was used in this research, involving 40 chemistry teacher participants in the province of North Sumatra, Indonesia. Participants were asked questions regarding their views on the need for assessment development through a questionnaire. Several of them were interviewed semi-structured to gain more in-depth information from the questionnaire answers. Data were analyzed using the Miles and Huberman model which consists of the steps: collection, reduction, display, and conclusion. The research results show that teachers agree that PBL-based formative assessments are needed to measure students' critical thinking skills. They suggest researchers choose Ennis's version of critical thinking indicators because they have good detail and warn researchers to practice Problem-Based Learning syntax correctly. Apart from that, it is hoped that successful learning in the classroom can be achieved through the use of products from the development of this formative assessment, namely test instruments and observation sheets.
