Colligative Properties

The research aimed to need analysis of developing Basic Chemistry learning tools based on inquiry. This was descriptive research. The subjects were a syllabus, two lectures, and 43 students of the Third Semester in Academic Year 2018/2019 on Science Education Study Program, Ganesha University of Education. The object was Basic Chemistry topics, the materials that are difficult for the students and their cause, lectures constraint in learning, and lectures view about learning based on inquiry. Data were collected by questionnaire and documentation. Data were analyzed by descriptively. The result showed that the Basic Chemistry topics include: material and its' change, atomic structure, periodic system of elements, chemical bonding and molecular structure, stoichiometry, thermochemistry, chemical kinetics, chemical equilibrium, acid and base, hydrolysis, buffer, colligative properties, colloid, redox and electrochemistry, elemental chemistry, and organics chemistry. All of the topics were considered difficult by a certain number of students. Most of student difficulties were found in the topics: stoichiometry, chemical kinetics, and colligative properties (58.14%), but the smallest in the topics: material and its' change, and atomic structure (13.95%). The students’ difficulties are caused by the abstract materials (23.26%), low of mathematics ability of students (34.88%), the students learning only for doing task/test (59.53%), low students’ prior-knowledge (46,51%), the students, habit to memorizing learning (51,16%), the students did not reflect their learning (53,48%), and the students easily forget the concepts learned (65,12). The lectures constraint in learning comprises designing and implementing of learning and assessment. The lectures said that the Basic Chemistry learning tools based on inquiry are important to be developed to facilitate the students in constructing the knowledge.

Colligative Properties

Guided discovery learning based E-module is a teaching material in electronic to support independent learning that follow the stages of guided discovery learning model. The development research was conducted to develop and analyse the validity and practicality of this e-module on colligative properties of solution material for class XII high school chemistry learning. The type of research is educational design research using the Plomp development model consisting of (1) preliminary research, (2) prototyping stage, (3) assessment phase. The e-module was validated by eight validators who are four UNP chemistry lecturers and four chemistry teachers using an instrument in the form of validity questionnaire, while the practicality test was carried out at SMA N 8 Padang by 27 students and three teachers with an instrument in the form of a practicality questionnaire. The questionnaire analysis was performed using the Content Validity Ratio (CVR) for content validation and Aiken V formula for construct validation and practicality. From the results, the data indicate that the solution based colligative properties e-module based on guided discovery learning for chemistry learning in class XII senior high school has valid and practical values.
