3.1. Assessment Form
The form of assessment that is most often carried out by lecturers in the natural field of science is 92.04% stating that the assessment most often carried out is a combination of test and non-test assessments. Meanwhile 8.64% only carry out the test. Meanwhile, in the field of social science, 84.57% stated that the most frequent assessments were a combination of test and non-test assessments. Meanwhile 8.64% only carried out the test and 6.79% only carried out the Nontest assessment (
Figure 1). So, the form of assessment carried out by the majority of lecturers at this time is a mixture of tests and non-tests. But the visible difference between the form of assessment in the social sciences and the natural field lies in the use of the non-test form only just found in the social sciences.
Meanwhile, test form in the field of natural sciences, most often carried out according to natural science lecturers are written tests of 45.95%, performance tests (performance) 37.39%, oral tests (interviews) 16.67%. Meanwhile, for social science lecturers, according to the lecturers, the form of tests that are most often carried out are written tests by 21.22%, performance tests (performance) 54.69%, oral tests (interviews) 24.08% (
Figure 2). The real difference seen in these two fields of science is that the use of written tests is mostly carried out by lecturers in the natural field, in contrast to lecturers in the social field who do more performance tests. This indicates a good implementation. Performance appraisal, portfolio assessment, and project appraisal are good authentic assessments to carry out. So, the implementation of the performance assessment has been carried out and needs to be supplemented with various other tests such as portfolio assessment and project assessment [
24]. The data above were corroborated by the previous research of [
25] that stated that to improve the effectiveness of mathematics learning, collaborative problem-based learning model with authentic assessment model could be considered as one of the learning models in the classroom. The benefit of authentic assessment is that students learn to develop and use self-regulated skills to achieve high learning goals [
26].
Difficulty level: The tests carried out according to the natural lecturer are 24% higher order thinking, case or analysis questions 29%, application questions 26%, easy questions 11%, reviews 11%. While social lecturers are 21% of difficult questions (Higher Order Thinking), 36% case or analysis questions, 27% application questions, 7% easy questions, 9% reviews/reviews. Some lecturers have different views with high-complexity questions not just HOTS, no written tests, a mixture of difficult and easy questions, multiple choice to not using tests at all.
The forms of non-test assessment that are most often carried out according to natural lecturers are activeness in conducting discussions 24%, mastery of material in discussions 25%, independent tasks 28%, group assignments 23%. While social lecturers are active in conducting discussions 25%, mastery of material in discussions 24%, independent assignments 27%, group assignments 24%, and the rest the level of attendance in class, self-reflection, projects, individual assignments, peer assessment, ethics, discipline, attitude, etc.
Meanwhile, for the written test, the level of implementation of the questions given are 56.6% higher order thinking questions, 82.7% case or analysis questions, 66.1% application questions, questions are classified as easy 24.7%, reviews/reviews 0.3%. Higher order thinking skills (HOTS) are an important aspect in the education system and are very good if they can be applied in authentic assessment [
27,
28]. Unfortunately, only 56.6% of lecturers have used questions with the HOTS difficulty level, the rest are mostly applied and analyzed. Meanwhile, the types of non-test assessments that are often carried out by lecturers are activeness assessments and discussions. Changing the testing and assessment practices is a long process that requires enormous effort from lecturers. The courage to try something new and to actively change their behavior and beliefs could be done; they are well motivated if there is a clearly defined theoretical basis [
29].
The form of the assessment carried out by the Lecturer of the State University of Malang turned out to have a difference between the natural sciences and the social sciences. The implementation of the form of test assessment is mostly carried out by the natural sciences field, while the social science field mostly conducts non-test assessments. As seen in
Table 3, there is a significant difference between natural sciences and social sciences in the form of non-test assessments.
In addition, the application of the high order thinking question has a difference. Natural science applies more questions to high order thinking than in the field of social science. As seen in
Table 4.
3.2. Assessment Technique
The assignments given by the lecturers consist of individual assignments and group assignments. The individual assignments that are most often carried out according to lecturers are making 48% summaries, making 55.4% papers, making 51.7% articles, doing 53% questions, 8.4% making books, and the others are reviews, product design, case analysis, making applied examples, essay projects, making presentations, making modules and learning media, case studies, answering questions, analysis/case studies, analyzing cases, making vlogs or video programs, practicing maps, preparing presentations, analyzing articles, making research proposals, making videos, compiling mind maps related to the material, and reporting reading results.
Table 5 shows that individual assignments in the form of writing articles have a real difference between social sciences and natural sciences. The field of social sciences gives more individual assignments in the form of making articles when compared to the field of natural sciences.
Meanwhile, the group assignments that are most often done according to natural science lecturers make 24% summaries, 76.6% papers, 41.4% articles, 27.8% project books, 11.9% reading reports, and so on. The assignments are group analysis, working on a project, review and presentation, working on a group project, social service projects and case studies, field measurements, discussions and performance observations/field visits, and project analysis/case studies.
From several assignment techniques that have been carried out by lecturers, the forms of assessment that can provide real experience to students according to lecturers are project assignments 78%, portfolio assignments 42%, case study assignments 72.6%. Other assignments that are considered to provide real experience to students are writing reflection textbooks, teaching skills tests, and observations.
In addition, in implementing the assessment, as many as 54.41% of respondents from natural science lecturers have carried out assignments that can assist students in obtaining, changing or developing skills, attitudes, ideals, appreciations, and knowledge. Meanwhile 41.18% rarely, 4.41% sometimes, and 0% never. Meanwhile, social science lecturers have carried out assignments that can assist students in obtaining, changing, or developing skills, attitudes, ideals (aspirations), appreciations (awards), and knowledge (knowledge) by 63.74%. Meanwhile 41.18% rarely, 4.41% sometimes, and 0% never (
Figure 3). There is no difference in the application of the assessment in the two fields of science.
3.4. Post-Assesment
The post-assessment process that has been carried out shows that as many as 45.90% of respondents lecturers of natural science provide feedback (discuss) on the results of the assessments that have been carried out, while 49.18% rarely, 4.92% sometimes, and 0% never. While the social sciences lecturer gave feedback (discussed) on the results of the assessment that had been done as much as 43.24%, while 50.00% rarely, 5.41% sometimes, and 1.34% never (
Figure 4).
The follow-ups that were carried out were discussion by lecturers (one way) for 46.6%, joint discussion (FGD) for 72.6%, 33.4% of enrichment assignments, personal comment, in-class discussion, review, self-assessment, improvement of results using new assignments with higher level, discussion and questions and answers.
In the post-assessment, the majority of lecturers rarely provide feedback to students. If any, the form of follow-up that was performed would be collective discussion, one-way discussion by lecturers, and provision of enrichment. This situation should be a concern and evaluation material following the implementation scale as stipulated in the Regulation of the Minister of National Education No. 35 of 2010, a scale below 40% indicates that implementation is still not maximal [
8]. The development of educational material that could be initiated through the students’ opinions during the feedback process [
29]. In relations to the three factors of problem-based learning, authentic assessment, and meaningful systems that are a combination of powerful tools in online learning, can provide education to students in effective digital learning [
26].
Through the collected data, it can be seen that almost all aspects of authentic assessment between the natural and social sciences had no differences. In relation with the opinion that stated that social objects are not the same as natural objects; however, it should not leave us with the view that reality interacts with constructs in certain domains and specific sciences [
14,
30]. The only differences are in the form of assessment and individual assignment techniques, as shown in
Table 6. Social science conducts more non-test assessments than natural science. This is understandable because sometimes, social objects are not definite and not measurable things so that a test assessment that contains specific parameters cannot be used in some areas of social science. Humanities and social sciences, in this respect, appear to be more complicated than chemistry and physics [
31]. Actually, in both the social and natural sciences, there are seven steps for optimal use of portfolio assessment: (1) planning, (2) preparation for the study, (3) collecting evidence, (4) monitoring progress, (5) improving performance, (6) reflection, and (7) displaying works [
32,
33].
Measured tests are more widely used in the field of natural science using higher-order thinking skill questions. The use of HOTS questions in several previous studies had a significant effect on students’ learning, competence, and science process skills [
28,
34]. Individual assignments in the form of writing articles are more widely used in social science concerning the learning outcome demands of multiple portfolios [
35,
36]. Both methods of assessment can be used, although not all problems in the natural and social sciences can be generalized. In practice, it would be better if an interdisciplinary approach is used [
37,
38], and a mixed assessment form could be used in this model.
The contextual nature of critical thinking is a concept, its complex interactions with disciplinary knowledge approaches, and diverse and complex epistemologies, for assessors of critical thinking for pedagogy, curriculum, and assessment [
39,
40]. All scientific fields can ultimately use the implementation of authentic assessment, but it must be adapted to the epistemology and conform the learning outcomes in its application.
Figure 5 shows the proposed authentic assessment model for natural science. The abbreviation AF refers to authentic form, and PA refers to post-assessment. Based on the model, the assessments are performed sequentially. However, the instructor has an option if the next section is not required, then it can skip to the next one. It aims to make an assessment quickly and efficiently.
Figure 6 illustrates the proposed authentic assessment model for social science. The illustration represents that the assessment in social science tends to be more flexible. In other words, the instructor has free control to perform a first assessment that relates and is suitable to learning conditions. Moreover, 20 lecturers from each field study have validated these two models so that it can be implemented in the learning activities.
The results of this study are useful for academia because they can provide an overview of how lecturers in the social and natural science fields translate learning goals that might be achieved in teaching students using the PBK approach, what authentic tasks they choose to teach, how to use them to improve the quality of the process and subsequent learning outcomes, and what follow-up was provided regarding each of the authentic assessments used. The results of this study are useful for the professional world because they can provide a foundation and inspiration to conduct more in-depth research in their respective fields, according to existing interests and needs.
The contribution of research results to the academic world related to authentic assessments include: (1) the process of seeking and finding information in the learning process, (2) the basis for making judgments, decisions, conclusions from an evaluation, (3) providing direct meaning in the educational process, for example real in biology learning that uses a process approach, while the contribution of research results to the professional world related to authentic assessments include: (1) authentic assessment known as performance assessment is a form of assessment that emphasizes professional performance related to the actual situation, (2) can know the attitude of professionals as expected, (3) allow to measure professional skills in a complex manner, and (4) enable the professionals being assessed to demonstrate their abilities in a real context.
The comparison between authentic assessments used in the social and natural science fields is useful as a source of information regarding various kinds of authentic assessments that can be used by each field of science. However, the use of this authentic assessment must still be adjusted to the learning objectives and the type of task chosen in achieving the goals to be achieved.
The benefits of authentic assessment research for other researchers are (1) it can be used as an effort to develop assessments that aim to assess individual abilities through certain tasks, determine learning needs, help and encourage students and educators (teachers) to become better at determining learning strategies, institutional accountability, and improving the quality of learning, while further research is required in (1) finding obstacles in conducting comprehensive, holistic, and consistent assessments, and (2) finding solutions in overcoming difficulties in improvising/developing valid and reliable research instruments.
