Implementation of Innovative Chemistry Learning Material With Guided Tasks to Improve Students’ Competence

Abstract

This research aimed to provide an innovative chemistry learning material with guided tasks to improve students’ competence in Chemistry. It involved 180 students enrolled in the Analytical Chemistry course at State University of Medan in academic year of 2016/2017. The samples were purposively selected and divided into two groups. The research consisted of several steps including enrichment, innovation and standardization of learning material, followed by implementation of the developed learning material in class. A set of good quality learning material equipped with the guided task for Gravimetry topic has been provided. It contained relevant contextual examples, laboratory works, students’ activities, multimedia, and hyperlink to trustworthy websites. Implementation of innovative learning material has been conducted by using a set of developed learning material in the experimental class while the existing textbook was used in the control class. The research findings highlighted several points: (1) well-implemented innovative learning material was effective to improve the students’ competence; (2) learning outcome in experimental class was found higher than that in control class; (3) the guided task in the learning package facilitated the students to learn the selected chemistry topic independently which in turn shifted student learning style from lecturer-oriented to student-oriented; (4) the guided task not only made the students be familiar with searching for scientific documents to complete the given tasks but also improved the students’ ability to write and organize their assignments; (5) students’ academic attitudes, observed during the learning activities, were categorized as very good. Keyword: innovative learning material, guided tasks, independent learning, students’ competence.

Effectiveness of Guided Discovery Based Thermochemistry Module to Train Critical Thinking Skills Based on Gender Differences

“…In addition, female students are better at processing textual information (Yang, 2016). Male students generally have more complex problems in learning, especially in chemistry, than female students (Dori et al, 2018;Situmorang et al, 2018).…”

The Development of Project-Based Innovative Learning Resources for Teaching Organic Analytical Chemistry

“…Project-based innovative learning resources are very effective when equipped with project examples in the form of videos that make it easier for students to learn independently. The learning resource package that is prepared in accordance with the KKNI is in accordance with the needs of students as prospective chemists [19,20]. Standard innovative learning resource packages are very effective in helping students learn Organic Analytical Chemistry.…”

The Development of Innovative Learning Resources with Multimedia to Support Online Learning in Teaching Industrial Management

“…The combination of teaching materials with multimedia available in the learning resources makes it easier for students to understand the concept of industrial management. Assignments that have been designed in this lecture have enriched students with learning experiences, while increasing knowledge in the material being studied [25]. Examples of tasks that are integrated into learning resources have succeeded in making student learning activities more meaningful, motivating students to spend more time studying online [26,27].…”
